Description

Technical Field

[0002] A battery refers to a part of a cup, tank or other container or composite container that contains an electrolyte solution and metal electrodes to generate current, and is a device that can convert chemical energy into electrical energy, which has positive and negative electrodes. With the progress of technology, a battery generally refers to a small device that can generate electrical energy.

[0003] When a battery is in use, heat will be generated, and this part of heat usually needs to be discharged in time. If it cannot be discharged normally, it will lead to a reduction in the service life of the battery, and even spontaneous combustion may occur. Therefore, in order to control the temperature of the battery during operation, a temperature control system is usually used for temperature regulation. The temperature control system generally includes structures such as a temperature sensor, a controller, and a refrigeration module. The temperature is monitored by the temperature sensor, and if the temperature is too high, the refrigeration module is controlled to refrigerate and cool down;

[0004] Common refrigeration modules include thermoelectric refrigeration modules. A thermoelectric refrigeration module generally consists of a thermoelectric cooler, a heat exchange base (with heat exchange fins arranged on the surface), and a cooling fan. The traditional heat exchange base only increases the heat exchange area through the heat exchange fins to obtain a better heat exchange effect. Although this method can increase the heat exchange effect to a certain extent, the heat exchange efficiency is still insufficient. Therefore, a battery temperature control refrigeration module is proposed to solve the above-mentioned problems. Summary of the Utility Model

[0005] Based on the above description, the utility model provides a battery temperature control refrigeration module to solve the problem of insufficient heat exchange efficiency of the existing thermoelectric refrigeration module.

[0006] The technical solution of the utility model to solve the above technical problems is as follows: A battery temperature control refrigeration module includes: a base, the base includes a top plate, an intermediate member, a mounting bottom block, and a fixing frame arranged in sequence from top to bottom. The mounting bottom block includes a mounting cylinder, a communication hole, and a mounting groove. The cooling fan is arranged inside the mounting groove through a cover plate. Tesla valves are respectively arranged between the mounting bottom block and the intermediate member, between two adjacent intermediate members, and between the intermediate member and the top plate. The thermoelectric cooler is arranged between the mounting bottom block and the fixing frame.

[0007] On the basis of the above technical solution, the utility model can be further improved as follows.

[0008] Further, the mounting bottom block includes a U-shaped bottom plate. The upper surface of the U-shaped bottom plate is provided with a mounting cylinder and a first card slot. The top end of the mounting cylinder is provided with a mounting groove.

[0009] Further, a communication hole is provided on the side wall of the installation cylinder, and the communication holes respectively correspond to the gaps between the installation bottom block and the intermediate piece, between adjacent intermediate pieces, and between the intermediate piece and the top plate.

[0010] Further, the intermediate piece includes a U-shaped plate, and second card slots are provided on both the upper and lower surfaces of the U-shaped plate, and the second card slots correspond to the first card slots.

[0011] Further, a first positioning opening is provided on the upper surface of the U-shaped plate, and the size of the first positioning opening is greater than or equal to the size of the installation cylinder.

[0012] Further, the top plate includes a main body plate, and a third card slot and a second positioning opening are provided on the lower surface of the main body plate. The size of the second positioning opening is equal to the size of the first positioning opening, and the third card slot corresponds to the second card slot.

[0013] Further, the fixing frame includes a frame main body, and a placement groove and a communication port are sequentially provided on the upper surface of the frame main body from top to bottom. A wire passing hole is provided on the side wall of the frame main body, and a semiconductor refrigeration sheet is provided inside the placement groove.

[0014] Further, the Tesla valve includes a valve body and a valve cover. A positioning blind hole is provided on one side of the valve body close to the valve cover, and a positioning post is provided on one side of the valve cover close to the valve body. The positioning post extends into the interior of the positioning blind hole.

[0015] Further, the Tesla valves are respectively arranged between the first card slot and the second card slot, between adjacent second card slots, and between the second card slot and the third card slot.

[0016] Compared with the prior art, the technical solution of the present application has the following beneficial technical effects:

[0017] 1. By arranging components such as a base, a Tesla valve, and a cooling fan, through the cooperation relationship between the cooling fan and the base, the air on both sides of the base can be inhaled into the interior of the installation cylinder under the action of the cooling fan and discharged from the top of the installation cylinder. During this process, the Tesla valve exchanges heat with the air, thereby achieving the effect of accelerating the heat dissipation of the semiconductor refrigeration sheet;

[0018] 2. By setting the Tesla valve, the effect of increasing the heat dissipation capacity is achieved. When air is inhaled from the gap between the Tesla valves, heat exchange occurs between the air and the outer surface of the Tesla valve. When air flows inside the Tesla valve, the air moves from the direction away from the installation cylinder towards the direction close to the installation cylinder. At this time, the air flow rate inside the Tesla valve increases. After the flow rate increases, the heated air after heat exchange is more easily discharged. Moreover, the internal structure of the Tesla valve is set to increase the heat exchange area, further enhancing the heat dissipation effect. Brief Description of the Drawings

The terms used in the specification of this application herein are only for the purpose of describing specific embodiments and are not intended to limit this application.

It should also be understood that the terms "comprising" or "having" etc. specify the presence of the stated features, wholes, steps, operations, components, parts or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0034] Please refer to Figure 1 、 Figure 2 and Figure 4 , the installation bottom block 1 includes a U-shaped bottom plate 11, an installation cylinder 13 and a first card slot 12 are provided on the upper surface of the U-shaped bottom plate 11, an installation groove 15 is provided at the top end of the installation cylinder 13, and a communication hole 14 is provided on the side wall of the installation cylinder 13. The communication holes 14 respectively correspond to the gaps between the installation bottom block 1 and the middleware 2, between adjacent two middleware 2, and between the middleware 2 and the top plate 3;

[0035] Based on the above, the setting of the first card slot 12 plays a role in positioning the Tesla valve 8, and the installation cylinder 13 plays a role in fixing the cooling fan 4. When the cooling fan 4 works, it can suck the external air into the interior of the installation cylinder 13 to achieve the effect of directional air flow.

[0036] As Figure 1 , Figure 2 , Figures 5 - 7 shown, the middleware 2 includes a U-shaped plate 21. Second card slots 22 are provided on both the upper and lower surfaces of the U-shaped plate 21. The second card slots 22 correspond to the first card slots 12. A first positioning opening 23 is provided on the upper surface of the U-shaped plate 21. The size of the first positioning opening 23 is greater than or equal to the size of the mounting cylinder 13;

[0037] The top plate 3 includes a main body plate 31. A third card slot 32 and a second positioning opening 33 are provided on the lower surface of the main body plate 31. The size of the second positioning opening 33 is equal to the size of the first positioning opening 23. The third card slot 32 corresponds to the second card slot 22;

[0038] Based on the above, the middleware 2 cooperates with the top plate 3 and the mounting bottom block 1 respectively to form a complete housing. This housing can fix the Tesla valve 8 and cooperate with the Tesla valve 8 to make the air flow direction fixed, that is, to move from the direction away from the mounting cylinder 13 towards the direction close to the mounting cylinder 13.

[0039] As Figures 1 - 3 shown, the cooling fan 4 is arranged inside the mounting groove 15 through a cover plate 5;

[0040] Based on the above, the cooling fan 4 plays a role in driving air flow. When the cooling fan 4 is powered on and working, the air inside the mounting cylinder 13 is pumped out, and then the air on the side of the mounting cylinder 13 is sucked into it.

[0041] As Figure 2 , Figure 3 , Figure 9 and Figure 10 shown, the Tesla valve 8 is respectively arranged between the mounting bottom block 1 and the middleware 2, between two adjacent middleware 2, and between the middleware 2 and the top plate 3;

[0042] The Tesla valve 8 includes a valve body 81 and a valve cover 83. A positioning blind hole 82 is provided on one side of the valve body 81 close to the valve cover 83. A positioning post 84 is provided on one side of the valve cover 83 close to the valve body 81. The positioning post 84 extends into the interior of the positioning blind hole 82. The Tesla valve 8 is respectively arranged between the first card slots 12 and the second card slots 22, between two adjacent second card slots 22, and between the second card slots 22 and the third card slots 32;

[0043] Based on the above, on the one hand, the Tesla valve 8 has the effect of increasing the heat exchange area. When the air flow is inhaled into the interior of the installation cylinder 13 along the Tesla valve 8, the heating end of the thermoelectric cooler 7 is in contact with the installation bottom block 1. At this time, heat is transferred to the Tesla valve 8, the intermediate member 2, and the top plate 3. When the air flows, the cold air from the outside can absorb and discharge the heat. The setting of the Tesla valve 8 makes the heat exchange area larger and the heat exchange operation easier. On the other hand, the special structure of the Tesla valve 8 plays a role in accelerating the air flow, making the air flow faster when flowing inside the Tesla valve 8. The faster flow rate will not only accelerate the heat transfer, making the heat inside the device follow the air and be discharged faster, but also the accelerated air flow can drive the air flow in other positions to move together, making the air flow rate in other positions increase together.

[0044] As Figures 1 - 3 and Figure 8 shown, the thermoelectric cooler 7 is arranged between the installation bottom block 1 and the fixing frame 6. The fixing frame 6 includes a frame main body 61. A placement groove 62 and a communication port 63 are sequentially arranged on the upper surface of the frame main body 61 from top to bottom. A wire routing hole 64 is arranged on the side wall of the frame main body 61. The thermoelectric cooler 7 is arranged inside the placement groove 62;

[0045] Based on the above, the thermoelectric cooler 7 is arranged inside the placement groove 62. At this time, the heating end of the thermoelectric cooler 7 is in contact with the lower surface of the installation bottom block 1, and the cooling end of the thermoelectric cooler 7 can be in contact with the battery through the communication port 63.

[0046] In actual use of this embodiment, through the setting of the communication port 63, the cooling end of the thermoelectric cooler 7 can be in contact with the battery when the refrigeration module is working, playing a role in cooling;

[0047] The heating end of the thermoelectric cooler 7 is in contact with the installation bottom block 1, so that heat can be transferred to the installation bottom block 1, the intermediate member 2, the top plate 3, and the Tesla valve 8. At this time, the installation bottom block 1, the intermediate member 2, the top plate 3, and the Tesla valve 8 all exchange heat with the air, so that the heat can flow and be discharged together with the air. When the cooling fan 4 is powered on and works, the air on both sides of the base is inhaled. The inhaled air is divided into two parts. One part is in contact with the outer surface of the Tesla valve 8, and the air flow speed of this part is slower. The other part enters the interior of the Tesla valve 8 and flows. After the action of the Tesla valve 8, the air flow speed of this part is faster. And when the air flow flows inside the Tesla valve 8, it can exchange heat together. And the air with a faster flow rate can take away the hot air faster, playing a better heat dissipation effect. And the air flow accelerated by the Tesla valve 8 can drive the air flow with a slower flow rate to move;

[0048] By setting up structures such as the top plate 3, the middle piece 2, and the mounting bottom block 1, the heat exchange area is increased, enabling the module to exchange more heat with the air. Through the setting of the Tesla valve 8, the air flow is faster, which not only increases the heat dissipation area, but also the faster air flow rate can dissipate heat more quickly, achieving a better heat dissipation effect and thus higher heat dissipation efficiency.

[0049] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
