Description

Heat abstractor, light source controller and camera system

Technical Field

Background

In high power consumption devices, such as light source controllers and cameras, they often require efficient heat dissipation solutions to maintain optimal operation. These devices often use thermoelectric coolers (also known as heat sinks made by the thermo-electric effect, which use the peltier effect) to cool and dissipate heat.

The working principle of the thermoelectric refrigerator is that when two different metals are connected through a conductor and direct current is introduced, the temperature of one side is reduced to form a cold surface, and the temperature of the other side is increased to form a hot surface. However, when the cold side temperature of the thermoelectric cooler is about 10 ℃ below ambient temperature, water vapor in the air may liquefy upon cooling, thereby producing condensed water.

The creation of such condensed water is a serious threat to electronic equipment. If condensed water flows into the inside of the equipment, problems such as rust, short circuit and pollution can be caused, and the performance and the service life of the equipment are seriously affected.

Therefore, how to reduce cold side condensate generation and effectively collect and process cold side condensate while cooling and dissipating heat using a thermoelectric cooler is a urgent problem to be solved by those skilled in the art.

Detailed Description

Embodiments of the present utility model are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The examples in the embodiments are intended to illustrate the present utility model and are not to be construed as limiting the present utility model.

Reference in the specification to "one embodiment" or "an example" means that a particular feature, structure, or characteristic described in connection with the embodiment itself can be included in at least one embodiment of the disclosure. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment.

In order to cope with the problem of condensed water generated on the cold side of thermoelectric coolers, several solutions have been proposed in the industry. One such method is to use hermetic isolation, which involves enclosing the thermoelectric cooler and the modules to be cooled, the soaking copper plate and its connecting cables, etc. all in a highly protected hermetic cavity, meeting the protection class of IP 68. To prevent the ingress of water vapor, it is necessary to assemble in a vacuum box or dry environment and place a desiccant in the cavity to absorb moisture. While this approach can effectively isolate moisture, it also presents design and cost challenges, including complex design, high cost, and inefficient assembly processes.

Another approach is to use a temperature sensor to monitor the difference between the cold side of the thermoelectric cooler and the ambient temperature through software control and to automatically shut down the device through background logic when the temperature difference is too large to prevent condensation. Although the method is direct, the potential failure risk exists, and the operation of the equipment is directly interrupted when the equipment is overheated, so that the performance of the equipment is influenced, the resource waste is possibly caused, and the user experience is influenced.

In view of these limitations of the existing solutions, the present solution provides in a first aspect a heat sink.

As shown in fig. 1, 2 and 3, the heat sink includes an air-cooled heat sink 20 and a refrigeration assembly 10. The refrigeration assembly 10 includes a thermoelectric refrigerator 200 and a condensed water absorber 400. The condensed water absorbing member 400 is formed with an opening, the thermoelectric refrigerator 200 is disposed in the opening, so that the periphery of the cold face of the thermoelectric refrigerator 200 can be completely wrapped, direct contact with the outside of air is avoided, and only the surface of the cold end of the refrigeration assembly 10 faces the outside of the opening, so that heat exchange is performed by being closely attached to a heat source, and an efficient heat dissipation function is realized. The housing 21 of the air-cooled radiator 20 is formed with a mounting hole 25 communicating with the inner cavity of the air-cooled radiator 20, and the condensed water absorbing member 400 is disposed on the mounting hole 25.

The condensed water absorbing member 400 has a microporous structure on both the surface and the inside thereof, which can effectively delay the contact of water vapor in the outside air with the cold side of the thermoelectric cooler 200.

In addition, the micropore structure also has the energy storage capability, and water vapor passes through the micropores and is condensed into liquid water in a low-temperature area, and the micropores can also effectively store the water vapor so as to prevent the condensed water from overflowing. When the micropores are sufficiently small in diameter, they also create capillary action, effectively transporting condensed water to other areas of the absorbent member, making the moisture distribution uniform and accelerating the removal of water by increasing the evaporation area. Particularly, as the condensed water absorbing member 400 is positioned on the mounting hole 25 communicated with the inner cavity of the air-cooled radiator 20, warm air flow generated during the operation of the air-cooled radiator 20 can dry the condensed water absorbing member 400 through the mounting hole and simultaneously quickly take away water vapor evaporated by the condensed water.

The heat dissipation device has the advantages of simple structure, low cost, easiness in processing and manufacturing, remarkable delay of the formation of condensed water, and high-efficiency collection and treatment of the generated condensed water, and avoids pollution of water drops to equipment, so that stable operation and long-term performance of the equipment are ensured.

In some embodiments, as shown in fig. 1, 2 and 3, the refrigeration assembly 10 includes a thermoelectric cooler 200 and a thermally conductive plate 100. The thermoelectric cooler has oppositely disposed cooling and heating surfaces. The thermally conductive plate 100 is disposed on a cooling surface of the thermoelectric cooler 200, and a surface of the thermally conductive plate 100 facing away from the cooling surface forms a surface of a cold side of the refrigeration assembly 10. The heat conductive plate 100 has excellent heat conductive properties, and copper is generally selected as a material because the copper heat conductive plate 100 has extremely high heat conductivity. The dimensions and thickness of the heat-conducting plate 100 are carefully designed to accommodate the heat dissipation requirements of different sized heat sources. The design principle ensures that heat can be effectively absorbed and transferred so as to meet the performance requirements in various heat dissipation scenes.

In some embodiments, as shown in fig. 1, 2, 4a and 4b, the condensed water absorbing member 400 includes a sleeve body 410 and at least one stepped portion 420 provided on an inner surface of the sleeve body 410. For example, when the heat conductive plate 100 and the thermoelectric cooler 200 have a circular shape, the stepped portion 420 in the case body 410 has a ring shape.

The opening is located on the sleeve body 410, and the step 420 is spaced from the opening. The heat conductive plate 100 is disposed in the sleeve body 410 between the stepped portion 420 and the opening, and a portion of the heat conductive plate 100 is disposed on the stepped portion 420. The thermoelectric refrigerator 200 is disposed in a defined space of the condensed water absorber 400 corresponding to the stepped portion 420.

In order to match the shapes and sizes of the heat conductive plate 100 and the thermoelectric cooler 200, the opening of the sleeve body 410 is precisely designed to ensure that the heat conductive plate 100 can be relatively precisely embedded therein, achieving a seamless connection, and preventing the generation of a large gap. The provision of the stepped portion 420 not only ensures a close fit with the edge of the heat conductive plate 100, but in some cases, the height of the stepped portion 420 is also designed to exceed the thickness of the thermoelectric cooler 200, considering that the condensate water absorbing member 400 may employ a deformable material such as a water absorbing sponge. Such a height difference allows a space for deformation of the material, and when the heat conductive plate 100 is closely attached to the thermoelectric cooler 200, the stepped portion 420 can be properly compressed, enhancing the connection strength of the contact surface, further ensuring tight coupling between the structures.

In some embodiments, as shown in fig. 4a and 4b, the sleeve body 410 includes two opposite first sidewalls and two opposite second sidewalls, and the two first sidewalls are located between and respectively connect the two second sidewalls. The step 420 is provided on an inner surface of the first sidewall.

In some embodiments, as shown in fig. 4a and 4b, a condensate water absorber 400 designed for a rectangular-shaped heat conducting plate 100 and thermoelectric cooler 200 is shown. The absorber includes two opposing steps 420 disposed on the inner surfaces of the two first sidewalls, respectively, which ensures perfect engagement with the rectangular heat-conducting plate 100 and the thermoelectric cooler 200, thereby providing an accurate and stable support surface, optimizing the heat transfer efficiency and sealing of the overall heat sink.

In some embodiments, as shown in fig. 2, the outside surface of the sleeve body 410 is in close contact with the inside surface of the mounting hole 25. This elaborate interface ensures continuity and tightness of the overall structure, enabling the heat sink to effectively collect condensed water during operation while preventing the ingress of external contaminants and moisture, thereby protecting the equipment from potential damage.

In some embodiments, as shown in fig. 3, the distance between the refrigeration assembly 10 and the first wall 22 of the housing 21 of the air-cooled radiator 20 is greater than the distance between the refrigeration assembly 10 and the second wall 23 of the housing 21 of the air-cooled radiator 20. The first and second housing walls 23 are here oppositely arranged, meaning that the refrigeration assembly 10 is not centrally placed in the housing 21 of the air-cooled radiator 20, but rather is more biased to the side closer to the second housing wall 23. To accommodate this asymmetric design, the location of the mounting holes 25 in the housing 21 of the air-cooled radiator 20 is also adjusted accordingly.

The refrigeration assembly 10 further comprises a soaking plate 300, wherein the soaking plate 300 is arranged on one side of the thermoelectric refrigerator 200, which is away from the heat conducting plate 100, and one side edge of the soaking plate 300 protrudes out of the thermoelectric refrigerator 200 and the protruding side is close to the second shell wall 23, that is, the extending direction of the protruding part of the edge of the soaking plate 300 extends from the mounting hole to the second shell wall 23, so that heat is conducted to the area between the first shell wall 22 and the second shell wall 23 of the shell 21 of the air-cooled radiator 20 as uniformly as possible. Similarly, the soaking plate 300 may be made of a material with a high thermal conductivity, such as a copper soaking plate 300.

In some embodiments, as shown in fig. 1 and 6, the soaking plate 300 is composed of two parts, a hole inner part 310 and a hole outer part 320. The bore interior 310 is located within the mounting bore 25 and the bore exterior 320 extends beyond the mounting bore 25. Structurally, the side wall of the hole interior 310 is kept spaced from the inner wall of the mounting hole 25, and a part of the condensed water absorbing member 400 is disposed in this space.

For soaking, the hole outer portion 320 is designed to closely match the surface of the area of the housing 21 of the air-cooled radiator 20 outside the mounting hole 25 for improving the heat radiation efficiency.

Further, the condensed water absorbing member 400 is provided with a relief notch 411 at one end near the mounting hole 25. The relief notch 411 enables the connection between the hole interior 310 and the hole exterior 320 to be in close contact with its surface, such an arrangement being intended to ensure structural consistency and optimization of the heat exchange effect.

In some embodiments, to fix the soaking plate 300, the housing extends out of an extension portion 25a in the mounting opening near the inner wall of the second housing wall, and the extension portion 25a extends toward the first housing wall, and the extension portion is integrally formed with the housing to provide a supporting surface for the soaking plate. Most areas of the extension parts are located in the coverage area of the vapor chamber so as to reduce occupation of the mounting holes.

In some embodiments, the hole outer portion 320 may be fastened to the case 21 of the air-cooled radiator 20 by a fastener on the one hand, and the heat conductive plate 100 may be fixed to the hole inner portion 310 by a fastener on the other hand, while pressing the thermoelectric cooler 200. Further, fasteners may also be provided on the extension 25 a.

Furthermore, in some embodiments, the refrigeration assembly 10 may be disposed on the air-cooled radiator 20 in a centered manner, that is, the mounting hole 25 is disposed in a centered position of the connection plate 24, the vapor chamber 300 is disposed in the middle of the mounting hole, and the periphery of the vapor chamber and the inner wall of the mounting hole form an annular space, which may be one or a plurality of continuous or discontinuous spaces, and the condensed water absorbing member 400 is disposed in the space and fills the space. The vapor chamber is fixed with the fins or connected with the area outside the mounting holes through a plurality of discontinuous connecting sections among the intervals. The arrangement of the refrigeration assembly 10 on the air-cooled radiator 20 can be flexibly set by a person skilled in the art according to the situation, and is not limited.

In some embodiments, in order to increase the heat transfer efficiency, a heat transfer medium may be disposed between the thermoelectric cooler 200 and the heat transfer plate 100, and/or between the thermoelectric cooler 200 and the soaking plate 300, and/or between the hole outer portion 320 of the soaking plate 300 and the surface of the case 21 of the air-cooled radiator 20. The heat conducting medium may be a material with high heat conductivity, such as heat conducting paste, heat conducting silicone grease, heat conducting pad or other type of heat interface material, which is used to fill up tiny uneven surface, thereby reducing air gap and improving heat energy transfer efficiency. In practical applications, the selection of a suitable heat-conducting medium needs to take into consideration compatibility, temperature resistance, heat-conducting property, long-term stability and other factors, so as to ensure that the heat-dissipating system can reliably operate.

In some embodiments, the condensate water absorbing element 400 may be constructed of one or more materials, including a water absorbing sponge, porous metal, microporous ceramic, porous membrane, and the like. These materials all have the ability to absorb and store moisture, thereby effectively managing condensed water caused by temperature differences during heat dissipation. The water-absorbing sponge can absorb and retain water through capillary action, and Polyurethane (PU) or polyvinyl alcohol (PVA) can be used as raw materials for manufacturing the sponge in material selection, and the materials have good water-absorbing performance and water storage capacity. Porous metals combine good thermal conductivity and moisture management, microporous ceramics are known for their micro and interconnected pore structure to adsorb and store moisture, and porous membranes generally have selective moisture permeability to effectively separate and manage water vapor. Which material is selected depends on the specific heat dissipation requirements, cost effectiveness, and application environment to ensure that the performance and reliability of the heat sink is optimized.

In some embodiments, as shown in FIGS. 1 and 5, the air-cooled heat sink 20 is formed of multiple components including a housing 21, at least one cooling fan 26, and a plurality of cooling fins 27.

The structure of the housing 21 is composed of a first housing wall 22 and a second housing wall 23 which are arranged oppositely and are connected by a connecting plate 24. The first and second housing walls 22, 23 stand parallel on a bottom wall of the device, for example on a bottom plate 34 of the housing of the light source controller. The connection plate 24 is opposite the bottom wall of the device, both of which are horizontally disposed.

These heat radiating fins 27 are arranged between the first and second case walls 23, spaced apart from each other to form an air passage for ventilation, thereby enhancing heat radiating effect. A cooling fan 26 is disposed at one end of the air ducts and serves to drive the air flow and accelerate the heat transfer process. Further, mounting holes 25 are provided on the connection plate 24 for fixing and connecting other components. The connection plate 24 of the air-cooled radiator 20 is designed to be placed horizontally so that the bottom of the condensate water absorbing member 400 is exposed to the bottom of the mounting hole 25 and serves as an air-receiving surface. The condensed water absorbing member 400 has a cavity structure for accommodating components of the thermoelectric cooler 200, the heat conductive plate 100, and the heat source, etc., which are extremely liable to generate condensed water on the surfaces thereof during operation. To ensure effective contact and fixation of these elements, the condensate water absorbing member 400 is tightly packed.

When the thermoelectric cooler 200 is operated and cooled, condensed water may be formed on the surface thereof if the surface temperature thereof is lower than the surrounding environment by 10 degrees or more. At this time, the upper stepped surface and the peripheral sidewall of the condensed water absorbing member 400 absorb the water by capillary action and gradually guide the water to the bottom of the absorbing member by gravity. Meanwhile, the operation of the radiator fan causes air to be blown toward the bottom of the condensed water absorbing member 400, and such a wind flow can promote evaporation of moisture in the water absorbing sponge, thereby effectively achieving dehumidification and maintaining dryness.

In some embodiments, one end of the condensed water absorbing member 400 passes through the mounting hole 25 and directly contacts on the heat radiating fin 27. This design enables the condensed water absorbing member 400 to be closely attached to the heat radiating fins 27, effectively absorbing and managing condensed water due to a temperature difference, preventing accumulation thereof and possibly adversely affecting the apparatus.

In addition, in a second aspect, the present disclosure also proposes a light source controller, as shown in fig. 1 and 7, where the light source controller includes a housing 31, at least one laser generator 39, a driving board 40 electrically connected to the laser generator 39, and a heat dissipating device as described above.

The cold end of the refrigeration assembly 10 is in close proximity to the heat exchanging surface of the laser generator 39 to effectively conduct heat away from the laser generator 39.

In some embodiments, the light source controller further comprises an optical fiber assembly 41, the housing 31 comprises a display operation panel assembly 32, an outgoing line panel 33 opposite to the display operation panel assembly 32, a bottom plate 34 and an upper cover 35 positioned between the display operation panel assembly 32 and the outgoing line panel 33, and the upper cover 35 is provided with three surfaces which are connected with the bottom plate 34 to form a rectangular cylindrical structure, wherein the display operation panel assembly 32 and the outgoing line panel 33 are respectively positioned at cylinder mouth positions at two ends of the cylindrical structure. The outlet panel 33 is provided with a special fiber outlet 36 for guiding one end of the fiber optic assembly 41 into connection with the laser generator 39 and allowing the other end of the fiber optic assembly 41 to protrude outside the housing 31 through the fiber outlet 36 for light source transmission.

In some embodiments, the design of the housing 31 further allows for improved heat dissipation efficiency, thus incorporating the vent 37, and a vent fan 38 mounted at the vent 37. Specifically, the vent 37 is provided on the upper cover 35 at a position close to the display operation panel assembly 32 side. The function of the ventilation fan 38 is to blow air into the interior of the outer case 31 or to discharge the hot air from the interior through the ventilation opening 37 to promote ventilation of the interior.

The utility model also provides a camera system, such as a linear array camera system and an area array camera system, which mainly comprises a camera and a light source controller as detailed in the second aspect. The light source controller provides the necessary light source for the camera through the built-in optical fiber assembly 41, so as to ensure that the camera has uniform and stable illumination support in the image capturing process.

Furthermore, since the light source controller incorporates the heat sink mentioned in the first aspect, it has an efficient thermal management function, and can maintain stability of the device under different operating environments. The design remarkably improves the reliability and performance of the camera system in a long-time running or changeable environment, ensures high efficiency and high precision of the image capturing process, and meets diversified application requirements.
