Description

A Cooler for Display Device

The present invention relates to a display cooling apparatus.

Liquid crystal displays (LCDs) and organic light emitting diodes (OLEDs), which are widely used as displays, can be manufactured in a flat plate shape and are becoming larger in size. If the temperature of the display rises, a malfunction may occur and an error such as failure to display the screen may occur. Therefore, during the operation of the display, cooling is also performed.

The causes of the display temperature rise include the temperature of the surrounding environment, direct sunlight, heat generated by brightening the display and brightening the display. Especially as the display becomes larger, efficient cooling of the display is more urgently required.

In consideration of this point, conventionally, a cooling structure for circulating air circulating through the front and rear surfaces of the display and discharging heat to the outside is applied. The circulating air discharges heat to the outside through a heat exchanger that discharges heat to the outside.

Since the circulating air passes through the front face of the display, if the circulating air is mixed with the outside air in the course of cooling, foreign matter enters the front of the display. Therefore, the above-mentioned circulating air is designed to circulate in an isolated state so as not to mix with outside air. In order to prevent the circulating air from mixing with the outside air, the heat is discharged from the heat exchanger through the heat conduction. Conventionally, the air in the closed circulation path circulating around the display module has a path circulating on the front, side, and rear sides of the display module.

The inside of the enclosure surrounding the periphery of the display module is likely to change into a high temperature environment by various heat sources. For example, the backlight unit of the display is illuminated so brightly when the surrounding environment is bright, so the amount of heat generated is not constant and varies depending on the surrounding environment. Also, when direct sunlight shines on the front face of the display, the internal temperature of the enclosure containing the display module is forced to rise to a high temperature.

However, in the case of the closed circulation path circulating around the conventional display module, the space inside the enclosure can not be partially cooled, and it has to be operated with a structure for cooling the entire space inside the enclosure. For example, when the amount of heat generated by the backlight unit is large in a state in which the amount of heat generated by other components in the housing is not large, the air in the closed circulation path described above may transmit the heat of the backlight unit to the entire interior of the enclosure.

Further, even when the display is exposed to direct sunlight and the inner space of the enclosure corresponding to the front surface of the display module is heated, the air in the closed circulation path transmits such heat to the inner space of the enclosure corresponding to the back surface of the display module.

SUMMARY OF THE INVENTION The present invention has been conceived to solve the above-described problems, and it is an object of the present invention to provide a refrigerator which circulates air circulating around a display independently in a space corresponding to a front surface and a rear surface, respectively, And an object thereof is to provide a display cooling apparatus which can control the display apparatus.

[Display Module]

A display module 10 applied to a display according to the present invention includes a front surface 11 on which a screen is provided, a rear surface 12 opposed to the front surface 11, And has a slender rectangular parallelepiped shape including a side connecting the front surface and the rear surface.

The side surface of the display module 10 includes two long sides and two short sides. An LED array constituting a part of the backlight unit 15 is disposed at the two long sides. Hereinafter, the two short sides are referred to as a first side and the second side, and the two long sides are referred to as a third side and a fourth side.

The LED array of the backlight unit 15 is fixed to the display module 10 by the housing 16. Further, the housing 16 further secures the rigidity of the display module 10 as a whole.

[Hull]

The housing 30 may have a hollow rectangular parallelepiped shape having a larger volume than the display module 10 and incorporating the display module 10. [ The enclosure (30) isolates the air circulating around the display module (10) from the outside of the enclosure inside the enclosure. Therefore, the air inside the enclosure is not mixed with the air outside the enclosure, thereby preventing foreign matter from entering the enclosure.

The front surface 35 of the housing 30 includes a glass as a transmitting surface for viewing the screen 11 of the display module housed inside the housing from outside the housing. The front surface 35 of the housing 30 and the front surface 11 of the display module 10 are slightly spaced. The rear surface 36 of the housing 30 is spaced apart from the rear surface 12 of the display module 10 and a PCB or the like for controlling and powering the display module 10 is disposed in this space.

The side surface of the housing 30 has a first side surface 31, a second side surface 32 facing the first side surface, a third side surface 33 facing the first side surface and the second side surface, And a fourth side 34. The first side 31 and the second side 32 may be short sides and the third side 33 and the fourth side 34 may be long sides.

The first side surface 31 and the second side surface 32 of the housing 30 may be disposed corresponding to the first side surface and the second side surface of the display module. The third side surface 33 and the fourth side surface 34, which are the long sides of the housing, may be disposed corresponding to the third side surface and the fourth side surface, which are long sides of the display module.

According to the present invention, the air circulates through the first closed circuit path 50 provided in the space between the front surface 35 of the housing 30 and the front surface 11 of the display module 10, The air circulates through the second closed loop path 60 provided in the spacing space between the display 36 and the rear surface of the display module 10. In the enclosure (30), the first closed circuit (50) and the second closed circuit (60) are separately provided. That is, the first closed loop path 50 and the second closed loop path 60 are not connected to each other.

Therefore, the side surface of the housing 30 and the side surface of the display module 10 do not necessarily have to be spaced apart to form a closed loop path.

However, since the first closed loop path 50 performs heat exchange with the air outside the enclosure at the side of the enclosure, the first closed loop path may have a section that flows along the inner side of the enclosure. This is also true for the second closed circuit. In this regard, the sides of the housing 30 and the side of the display module 10 may be spaced apart. However, the separation of the side surfaces of the housing 30 and the display module 10 is not intended to constitute a closed loop circulating the front, side, and rear of the display module in the housing.

Of course, the air in the first closed circulation path and the air in the second closed circulation path do not have to be completely sealed with each other, and even if some of them are mixed, the function or operation of the display cooling apparatus of the present invention is not affected.

[First Embodiment]

1 to 3, a first embodiment of a display to which a cooling device according to the present invention is applied will be described.

The display module 10 is installed inside the housing 30. The front surface 11 and the rear surface 12 of the display module 10 are spaced apart from the front surface 35 and the rear surface 36 of the housing 30, respectively.

In the space between the front face 35 of the housing and the front face 11 of the display module, the first closed circuit 50 of air is formed by the first fan 51. [ The first fan is provided at corner portions opposed to each other in a rectangular parallelepiped space between the front surface 35 of the housing and the front surface 11 of the display module and presses the air in mutually opposite directions. Therefore, the first closed loop path 50 circulates in the space provided in front of the display module 10 along the first side which is the short side, the third side which is the long side, the second side which is the short side, and the fourth side which is the long side Closed loop path. The circulating air travels along the illustrated closed loop path 50 and receives heat generated from the front surface 11 of the display.

Likewise, in the space between the rear face 36 of the enclosure and the rear face 12 of the display module, a second closed circuit 60 of air is formed by the second fan 52. The second fan is provided at the corner portions opposed to each other in the space of the rectangular parallelepiped body between the rear surface 36 of the housing and the rear surface 12 of the display module and presses the air in mutually opposite directions. Therefore, the second closed loop path 60 circulates along the first side which is a short side, the third side which is a long side, the second side which is a short side, and the fourth side which is a long side in a space provided behind the display module 10 Closed loop path. The circulating air travels along the illustrated closed-loop path 60 and receives heat generated at the rear surface 12 of the display.

2 and 3 illustrate that the first closed circuit and the second closed circuit path move in the anteroposterior direction of the display, And are spaced apart in the forward and backward directions. That is, the exact path of the first closed loop path and the second closed loop path can be understood with reference to the paths 50 and 60 shown in FIG.

A side heat exchanger (40) for receiving heat of air flowing along the closed circulation paths (50, 60) and discharging the heat to the outside of the enclosure is provided on a side surface of the enclosure (30). The side heat exchanger (40) has a second pin (44) protruding toward a space inside the housing and a first pin (43) protruding toward a space outside the housing. The first pin 43 and the second pin 44 share a pin base 46 disposed on the side surfaces 33 and 34 that separate the inner space and the outer space of the housing 30.

The second pin (44) extends in the longitudinal direction of the side of the display. The side heat exchanger 40 also includes a duct for guiding air in the closed circulation path 50, 60 surrounding the second fin 44 and flowing around the second fin. That is, the second pin 44 may be provided inside the duct (although the structure in which the first pin and the second pin are exposed to the outside and the inside of the housing, respectively, without a duct, is also applicable).

Air in a section passing through the third side surface and the fourth side surface portion of the first closed loop path (50) and the second closed circulation path (60) provided with the side heat exchanger can flow inside the duct. The duct or the second fin 44 that receives the second pin 44 contacts the side surface of the display module 10 on the side surface of the housing 30.

Therefore, in the path of the air of the first closed circulation path (50) among the second fins (44) provided in the duct, the second fin in contact with the air of the first closed circulation path flows from the air of the first closed circulation path Receives heat and cools the air in the first closed loop path.

And a second fin in contact with the air of the second closed circuit path in a path of the air of the second closed circuit path (60) among the second fins (44) provided in the duct is opened from the air of the second closed circuit path And cools the air in the second closed loop path.

The second pin of the second pin (44) provided in the duct is in contact with the side surface of the display module and receives heat from the backlight unit (15) and the housing (16) provided on the side of the display module, The unit 15 is cooled.

The heat transmitted to the second pin 44 is transmitted to the first pin 43 via the pin base 46.

The first pin 43 is exposed to the outside of the housing 30 and the first open flow path 70 is provided at the exposed portion of the first fin 43. The first open flow path 70 may be in the form of a duct surrounding the first pin 43. A third fan (not shown) is installed at both the inlet and the outlet, or both the inlet and the outlet of the duct, so as to pressurize the air so that the external air can move at a high flow rate within the duct. The third fan can be installed at the inlet of the duct and forcedly blowing the outside air into the duct. Also, the third fan may be installed at the exit of the duct to forcefully exhaust the air inside the duct to the outside of the duct.

The first open flow path (70) is shaped to extend along the longitudinal direction at the side of the housing (30). The first pin 43 also has a plurality of protrusions extending along the longitudinal direction of the side surface of the housing 30, like the second pin. Referring to FIG. 1, the first pin 43 protrudes from the side surface of the housing 30 and may reach the opposite surface of the duct opposite to the side surface of the housing to form a channel.

According to the above-described structure, the first pin and the second pin extend in directions parallel to each other. The first closed circuit path 50 and the second closed circuit path 60 and the first open flow path 70 include a flow along the side edge of the enclosure 30 and the side heat exchanger 40 The air flow of the first closed circulation path 50 and the air flow of the first open flow path 70 are parallel to each other and the second closed circulation path 60 performing heat exchange in the side heat exchanger 40, And the air flow of the first open flow path 70 are parallel to each other.

The first closed circuit path 50 and the second closed circuit path 60 are disposed closer to the display module 10 than the first open flow path 70 on the side of the housing 30.

In the first embodiment, the side heat exchanger is provided at a long side portion. However, the side heat exchanger is not necessarily installed at the long side, but may be provided at the short side or both the long side and the short side.

The first fan (51) and the second fan (62) circulate air in the front space and the space behind the display module, respectively, in the housing. The air in the first closed circuit path generated by the first fan 51 cools the heat generated on the screen of the display and when direct sunlight heats the inside of the enclosure through the front surface 35 of the enclosure, . The air in the second closed circuit path generated by the second fan 62 cools the heat generated in the substrate or the electronic device disposed on the rear side of the display module.

Accordingly, the operation control of the first fan and the second fan can be independently controlled according to the necessity of cooling the front space of the display module and the necessity of cooling the rear space. For example, when the direct sunlight is irradiated strongly, the first fan rapidly rotates independently of the second fan, so that the front space of the display module can be further cooled.

On the other hand, the LED array 15 of the backlight unit provided on the side of the display module 10 is a central heating region. Accordingly, in the present invention, the heat generated at the heat generating portion is directly cooled by the side heat exchanger (40). That is, the backlight unit 15 can be cooled separately from the cooling method passing through the closed loop paths 50 and 60.

Conventionally, since the heat generated in the backlight unit 15 is cooled by the circulating circulation path circulating around the front and rear sides of the display module, heat generated in the backlight unit tends to spread to all the spaces around the display module. However, according to the present invention, the heat generated in the backlight unit 15 can be immediately discharged to the outside of the housing through the side heat exchanger 40 disposed adjacent thereto.

The display module 10 is provided with a housing 16 which contacts the LED array and supports the outer shape of the display module 10. The housing 16 is structured to support stiffness of the display module 10, and is preferably made of a metal material. The metal housing 16 may be made of a material having an excellent thermal conductivity. Therefore, in the present invention, the housing 16 can enclose the side and rear portions of the display module 10 to secure the rigidity of the display module 10. At the same time, a portion of the side heat exchanger (40) is installed to abut the housing portion disposed on the side of the display module (10). Accordingly, the housing portion may be a heat transfer path for allowing the heat of the LED array to be rapidly transferred to the side heat exchanger.

Referring to FIG. 3, among the channels of the duct accommodating the second fin 44, the air flowing in the first closed loop path 50 flows to the channels disposed in contact with the side surface of the display module 10 Or the air of the second closed circuit path 60 may flow and the air of the first open flow path 70 may flow.

On the other hand, a rear heat exchanger (20) is provided on the rear surface of the housing (30) so that heat can be exchanged between the air in the second open flow path (80) outside the enclosure and the air in the second closed circuit path . The second open flow path 80 may be a path through which air is forced to flow by a fourth fan (not shown). When the second open flow path 80 is formed in such a manner that air is forced to flow by the fourth fan, the second open flow path 80 in the rear heat exchanger corresponds to the second open flow path 80 as shown in FIGS. So that the portion of the duct can have a duct shape.

Of course, the second open flow path 80 may be formed by natural air flow. In this case, in order to smoothly form the natural air flow, unlike the one shown in FIG. 1 to FIG. 3, the rear surface of the housing 30 is not exposed to the outside air It might be.

That is, the rear heat exchanger 20 shown in FIG. 3 may be additionally provided. Even if the rear heat exchanger 20 is omitted, as shown in FIG. 4, The air outside the enclosure 30 and the air inside the enclosure 30 are opposed to the rear surface 36 of the enclosure 30 so that heat exchange can be carried out through the rear surface of the enclosure 30 between them.

The second open flow path 80 of outside air flowing through the rear heat exchanger 20 is connected to the display module 10 via a second closed circuit path 60 flowing in contact with the back surface heat exchanger 20 or the rear surface of the enclosure. 10). ≪ / RTI >

 [Second Embodiment]

Hereinafter, a second embodiment of the present invention will be described with reference to FIG. The description of the contents overlapping with the embodiment described above will be omitted.

The main difference of the second embodiment with respect to the first embodiment is that the structure of the side heat exchanger 40 is different.

The side heat exchanger 40 in the second embodiment is installed on the side surface of the housing 30 as shown and includes a plurality of first ducts 41. The plurality of first ducts 41 constitute a plurality of channels through which the air of the first open flow path 70 flows. The first duct 41 extends along the longitudinal direction of the side surface of the housing.

The air in the first closed circulation path 50 flows in contact with the first duct 41 in the housing 30 and discharges heat to the air in the first open flow path 70 flowing in the first duct do.

The air in the second closed circulation path 60 also flows in the air of the first open flow path 70 flowing in contact with the first duct 41 in the housing 30 and flowing in the first duct, Release.

Since the backlight unit 15 provided on the side of the display module also contacts the first duct 41 through the housing 16, the air is blown into the air of the first open flow path 70 flowing in the first duct Releases heat.

[Third Embodiment]

A third embodiment of the present invention will be described below with reference to FIG. The description of the contents overlapping with the above-described embodiments will be omitted.

The air in the first closed circulation path 50 and the air in the second closed circulation path 60 are introduced into the side of the first duct 41 of the side heat exchanger 40 in the third embodiment, And the second duct 42 is further provided. That is, the second duct 42 is disposed closer to the display module 10 than the first duct 41. The second duct 42 may be disposed inside the enclosure 30 and the first duct 41 may be disposed outside the enclosure 30. [

Thus, if the closed loop paths 50 and 60 form a flow channel that exchanges heat with the first open flow path 70, the heat exchange efficiency can be higher.

In the third embodiment, the closed circulation paths 50 and 60 and the first open flow path 70 pass through the second duct 42 and the first duct 41, respectively, in the first embodiment, 50 and 60 and the first open flow path 70 pass through a duct accommodating the second fin 44 and a duct accommodating the first fin 43 respectively It has already been described that the first pin and the second pin are not accommodated in the duct, that is, the structure in which the duct is omitted).

[Fourth Embodiment]

Hereinafter, a fourth embodiment of the present invention will be described with reference to FIGS. 7 to 9. FIG. The description of the contents overlapping with the above-described embodiments will be omitted.

Unlike the first to third embodiments, in the fourth embodiment, the side surface of the display module 10 is separated from the side surface of the enclosure 30, and the first duct 41 constituting the open flow path 70 There is a first difference in that it passes through the housing 30 and contacts the side surface of the display module 10. [

In the fourth embodiment, the second duct 42 through which the air in the closed circulation path 50 flows is disposed farther from the display module 10 than the first duct 41. That is, the first duct 41 and the second duct 42 are installed in a space separated between a side surface of the display module 10 and a side surface of the enclosure 30.

In the vicinity of both ends of the first duct 41, a through space 45 communicating a space in front of the display module 10 and a space of the second duct 42 is provided. The air in the first open flow path flowing in the first duct 41 and the air in the first closed circulation path flowing in the penetration portion 45 do not mix with each other.

Next, the fourth embodiment differs from the above-described embodiments in a second point in that the first closed loop path 50 includes two circulation paths.

Air is introduced from the first side 31 of the enclosure toward the second side 32 of the enclosure by the first fan 51 in a space provided in front of the front surface 11 of the display module 10 in the enclosure 30 . Air moving in contact with the front portion of the display module 10 by the first fan 51 is diverted to the second side 32 and then to the third side 33 and the fourth side 34, And then flows toward the first side 31 along the second duct 42 provided on the third side 33 and the third side 34, respectively. Thus, the first closed loop path 50 includes the first-first closed loop path 50-1 and the first-second closed loop path 50-2.

If the first closed loop path 50 includes the first-first closed loop path 50-1 and the first-second closed loop path 50-2 as described above, the air circulating through the first closed loop path 50 is displayed on the display (A so-called dead zone) does not occur in the screen portion of the display module 10 because the entire area of the front surface 11 of the module 10 is in contact with the whole area.

9, in the fourth embodiment, both side surfaces of the display module 10 are in contact with the side heat exchanger 40, and the second closed circuit path 60 is in contact with the side heat exchanger 40, The side heat exchanger 40 and the rear heat exchanger 20 from the rear side of the housing.

[Fifth Embodiment]

Hereinafter, a fifth embodiment of the present invention will be described with reference to FIG. The description of the contents overlapping with the above-described embodiments will be omitted.

The fifth embodiment differs from the fourth embodiment in that the second duct is in a further extended form to the side portion of the display module 10. In the fourth embodiment, only the first duct 41 is provided on the side surface of the display module 10, and the second duct 42 is provided on the side of the space on the front surface 11 of the display module 10, (See Fig. 9).

According to the structure of the fifth embodiment, since the flow cross-sectional area of the second duct 42 is wider, compared with the second duct 42 of the fourth embodiment in which the flow cross-sectional area is relatively narrow, the flow rate of air flowing through the second duct And it is also possible to circulate air circulating through the first-first pulmonary path and the first-second pulmonary path more smoothly.

In the above-described embodiments, the closed loop paths 50, 50-1, 50-2, and 60 and the open flow paths 70 and 80 are adjacent to each other and flow in parallel or cross flow and mutual heat exchange is performed. In the heat exchangers 40 and 20 described above, the two paths can flow adjacent to each other.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the scope of the invention is not limited to the disclosed exemplary embodiments. It is obvious that a transformation can be made. Although the embodiments of the present invention have been described in detail above, the effects of the present invention are not explicitly described and described, but it is needless to say that the effects that can be predicted by the configurations should also be recognized.
