Background technique

Electronic products need to be powered by a battery device to operate. However, when the battery device outputs electric energy, it will also generate heat energy. If the heat energy is not effectively removed and accumulated in the battery device, the performance of the battery device may be reduced. Therefore, an effective heat dissipation method is very important for the operation and service life of the battery device.

The conventional solution to the heat dissipation problem of the battery device is mostly to install a plurality of heat sinks on the battery device, and use the convection between the heat sink and the air to dissipate the heat energy of the battery device.

Even if a plurality of fans are further installed near the heat sink to blow towards the heat sink, the improvement of the heat dissipation effect is also limited, but the cost of the battery device and the space it occupies are relatively low. will increase.

Therefore, some people propose to use water cooling to solve the heat dissipation problem of the battery device, such as disclosed in US Patent Publication No. US2009/0258288, which uses a water cooling plate to remove the heat energy of the battery. Although the water cooling plate can quickly dissipate heat energy, due to its geometric shape, the thickness of the battery device is greatly increased.

To sum up, how to improve the heat dissipation efficiency of the battery device without greatly increasing the thickness of the battery device is an urgent goal for the industry.

Detailed ways

Please refer to FIG. 1 to FIG. 3 , which are respectively an exploded perspective view, an assembled perspective view and a side view of a battery device 1 according to a first embodiment of the present invention. The battery device 1 includes a fixing frame 11 , at least one battery body 12 , a heat dissipation structure 13 and two sealing rings 14 ; the technical content of each component will be described in sequence below.

The fixing frame 11 is used to carry and fix the battery body 12, and is roughly in the shape of a rectangular plate, and may have a first side 111, a second side 112, a third side 113 and a fourth side 114; One side 111 is separated from the second side 112, the third side 113 is separated from the fourth side 114, the third side 113 is connected to the first side 111 and the second side 112, and the fourth side 114 is also connected to the first side 111 and second side 112 .

In this embodiment, the first side 111 is the rear side of the fixed frame 11, the second side 112 is the front side of the fixed frame 11, the third side 113 is the right side of the fixed frame 11, and the fourth side 114 is the fixed frame 11 on the left side.

In addition, an accommodating space 115 is formed between the first side 111 and the second side 112 ; in other words, the accommodating space 115 is recessed on the first side 111 and extends to the second side 112 .

The battery body 12 can be used to store and release electric energy, and is roughly in the shape of a rectangular plate. The battery body 12 can be disposed in the accommodating space 115 of the fixing frame 11 , and at least one side (such as a rear side) of the battery body 12 exposes the fixing frame 11 . In this embodiment, both the front side and the rear side of the battery body 12 expose the fixing frame 11, so the rear side and the front side of the battery body 12 can be observed from the first side 111 and the second side 112 of the fixing frame 11, respectively. .

It should be noted that there are two battery bodies 12 in this embodiment, and they are arranged side by side in the accommodating space 115 . However, for those skilled in the art, the number of battery bodies 12 can be easily increased or decreased according to power supply requirements, and the size and shape of the accommodating space 115 of the fixing frame 11 can be adjusted according to the number of battery bodies 12 .

The heat dissipation structure 13 is used to dissipate the heat energy of the battery body 12 , and it can be made of a material with a high thermal conductivity, such as aluminum, copper or ceramics. The heat dissipation structure 13 may include a plate body 131 and two blocks 132 , and the plate body 131 is connected to the two blocks 132 , and the two blocks 132 are respectively disposed on the left and right sides of the plate body 131 . In addition, the plate body 131 is thinner than the block body 132 , and the plate body 131 and the block body 132 are integrally formed. Each block 132 has a first input hole 1321 and a first output hole 1322 spaced apart from each other, which can respectively allow liquid to flow therethrough.

When assembling with the fixed frame 11 and the battery body 12, the plate body 131 is arranged on the first side 111 of the fixed frame 11, which means that the plate body 131 can fit the first side 111, sink into the first side 111, or be in contact with the first side. 111 maintains a gap; the state of this embodiment is that the plate body 131 leans against the first side 111 . The plate body 131 is further in contact with the battery body 12 , in detail, since the rear side of the battery body 12 partially exposes the fixing frame 11 , the plate body 131 can contact the rear side of the battery body 12 .

The two blocks 132 are respectively arranged on the third side 113 and the fourth side 114 of the fixed frame 11, which means that the block 132 can be combined with the third side 113 (the fourth side 114) and sink into the third side 113 (the fourth side 114). 114), or maintain a distance from the third side 113 (the fourth side 114); in this embodiment, the block 132 maintains a distance from the third side 113 (the fourth side 114).

In addition, the block body 132 can be located between the first side 111 and the second side 112 of the fixed frame 11, and will not protrude from the first side 111 and the second side 112; in other words, the thickness of the block 132 will not be greater than that of the fixed frame. 11 (meaning the shortest distance from the first side 111 to the second side 112). Therefore, the overall thickness of the battery device 1 will not greatly increase due to the arrangement of the block body 132 .

Next, the heat dissipation mechanism of the heat dissipation structure 13 will be described. When the battery body 12 outputs electric energy, it also generates heat energy. Since the plate body 131 of the heat dissipation structure 13 is in contact with the battery body 12 , the heat energy of the battery body 12 can be transferred to the plate body 131 through a heat conduction mechanism; the heat energy transferred to the plate body 131 will be further transferred to the block body 132 . Since the lower temperature liquid continuously flows through the first input hole 1321 and the first output hole 1322 of the block 132 , heat energy of the block 132 can be taken away by the liquid. In this way, heat energy is not easily stored in the battery body 12 and the heat dissipation structure 13 , so that the temperature of the battery body 12 will not rise too much.

It should be noted that the number of blocks 132 in this embodiment is two, which is to increase the heat dissipation effect of the heat dissipation structure 13 . However, the user can also reduce the number of blocks 132 to one (not shown in the figure) according to the actual heat dissipation requirement. In addition, the number of the first input hole 1321 and the first output hole 1322 of the block body 132 is not limited to one, and there may be more than one, so as to increase the flow rate of the liquid flowing through the block body 132 .

Next, the seal ring 14 will be described. Each sealing ring 14 can be provided with the first input hole 1321 and the first output hole 1322 of one of the blocks 132, or in other words, the openings of the first input hole 1321 and the first output hole 1322 are located in the sealing ring 14, and are The sealing ring 14 surrounds; thus, when the block 132 is stacked with the block 132 of another battery device 1 (see FIG. 4 ), the gap between the stacked two blocks 132 can be filled by the sealing ring 14, so that The liquid flowing in the first input hole 1321 or the first output hole 1322 will not leak from the gap.

It should be noted that the number of sealing rings 14 corresponds to the number of blocks 132 , so if the number of blocks 132 is reduced to one, the number of sealing rings 14 will also be reduced to one.

The above is the description of the battery device 1 of the first embodiment.

Please refer to FIG. 4 to FIG. 6 , which are respectively an exploded perspective view, an assembled perspective view and a perspective cross-sectional view of the battery device module 2 according to the second embodiment of the present invention.

After stacking, the plate body 131 of the heat dissipation structure 13 of these battery devices 1 is not only in contact with its own battery body 12, but also in contact with the battery body 12 of the adjacent battery device 1; in other words, the plate body 131 of each heat dissipation structure 13 The body 131 will be sandwiched between the two battery bodies 12 .

In addition, after stacking, the first input holes 1321 of the battery devices 1 are connected, and the first output holes 1322 of the battery devices 1 are also connected, so that the liquid can continuously flow through the first holes 1322 of the battery devices 1 . The input hole 1321 or the first output hole 1322 . And each sealing ring 14 is clamped between two blocks 132 , so that the liquid flowing in the first input hole 1321 or the first output hole 1322 will not leak from the gap between the blocks 132 .

Next, the fixing device 21 will be described. The fixing device 21 is used to provide a clamping force on the battery devices 1 so that the battery devices 1 can be kept stacked without being separated. The fixing device 21 includes a plurality of screws 211 , two first pressing blocks 212 and two second pressing blocks 213 .

The first pressing block 212 abuts against the block 132 of the first battery device 1 , and the second pressing block 213 abuts against the block 132 of the last battery device 1 , in other words, the blocks 132 of the heat dissipation structures 13 Clamped between the first pressing block 212 and the second pressing block 213 .

The groove 2132 communicates with the first input holes 1321 and the first output holes 1322 . In this way, the liquid can flow from the third input hole 2121 into the first input holes 1321 , then flow into the first output holes 1322 through the groove 2132 , and then flow out from the third output hole 2122 .

The screws 211 are connected to the first pressing block 212 and the second pressing block 213, and pass through the heat dissipation structure 13 of the battery device 1; in detail, the heads of the screws 211 can be pressed against the first pressing block 212 , and the threaded ends of the screws 211 can be screwed into the threaded holes of the second pressing block 213 . By increasing the feed rate of the screw 211, the distance between the first pressing block 212 and the second pressing block 213 will be shortened, causing the heat dissipation structures 13 to be pressed by the first pressing block 212 and the second pressing block 213 to be tightly stacked. .

These joints 22 can be respectively connected to the third input hole 2121 and the third output hole 2122 of the first pressing block, so as to facilitate the connection of water pipes (not shown). In this way, the liquid can be injected into the third input hole 212 through the water pipe, and then flow out from the third output hole 2122 into the water pipe. The connector 22 can be a quick connector or the like.

The battery device module 2 of this embodiment also utilizes the flow of liquid to rapidly remove the heat energy generated by the battery body 12 . In detail, the heat energy generated by the battery body 12 is first transferred to the heat dissipation structure 13, and then the liquid flowing through the first input hole 1321 and the first output hole 1322 of the heat dissipation structure 13 will continuously take away the heat energy, so that the heat energy is not easy to accumulate in the heat dissipation structure 13. In the battery body 12 and the heat dissipation structure 13 , the temperature of the battery body 12 will not rise too much.

The above is the description of the battery device 2 of the second embodiment. According to the aforementioned first and second embodiments, those skilled in the art can also deduce other similar implementations, such as the following.
