Description

Technical Field

[0001] This utility model relates to the field of battery pack heat transfer technology, and more specifically, to a heat transfer device for high-power silicon-carbon supercapacitive battery packs. Background Technology

[0002] Silicon-carbon batteries, as an emerging energy storage technology, have attracted much attention. Moreover, silicon-carbon batteries are a high-energy-density battery technology based on silicon and carbon materials. High-power silicon-carbon supercapacitor battery packs are battery packs composed of multiple individual silicon-carbon batteries. Battery pack failures, such as those caused by mechanical stress or short circuits within the battery pack, can lead to overheating. External heating, overcharging of the battery pack, exceeding the allowable battery voltage, or deep discharge of the battery pack can also cause overheating. After the battery heats up, heat transfer is often required to dissipate the heat of the battery pack and achieve heat dissipation and cooling.

[0003] Existing battery heat transfer methods involve placing phase change material separators on both sides of individual cells to transfer heat. However, with the accumulation of time and space limitations, the heat transfer effect of the separators with phase change materials gradually decreases, resulting in the inability to transfer and dissipate heat. This leads to a gradual increase in the overall battery temperature. When the temperature exceeds the normal operating temperature range of the battery, thermal runaway is likely to occur, affecting the safety of the entire battery pack. Therefore, a heat transfer device for high-power silicon-carbon supercapacitive battery packs is proposed. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a heat transfer device for high-power silicon-carbon supercapacitive battery packs to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a heat transfer device for a high-power silicon-carbon supercapacitive battery pack, comprising a supporting base box, a heat-conducting plate provided on the top wall of the supporting base box, multiple first through holes provided on both the heat-conducting plate and the bottom wall of the supporting base box, multiple heat-conducting rings fixedly connected to the middle of the supporting base box, and partition plates symmetrically fixedly connected to both sides of the inner cavity of the supporting base box, with second through holes provided on the surface of the partition plates;

[0006] The support base is connected to an inlet pipe and an outlet pipe on both sides, and a high-power silicon-carbon supercapacitor battery is installed on the top of the support base. Both sides of the high-power silicon-carbon supercapacitor battery are equipped with partitions. Multiple positioning plates are fixedly connected to the bottom of the partitions, and connecting ears are fixedly connected to the top of the partitions.

[0007] Preferably, the inlet pipe and outlet pipe are respectively located on opposite sides of the two partition plates, and the plurality of heat-conducting rings are located between the two partition plates.

[0008] Preferably, the first through hole and the heat-conducting ring correspond one-to-one, the cross-sectional shape of the heat-conducting ring is the same as that of the first through hole, and the top wall of the heat-conducting ring is fixedly connected to the bottom wall of the heat-conducting plate.

[0009] Preferably, the size of the first through hole is adapted to the positioning insert plate, the first through hole and the positioning insert plate correspond to each other, and the positioning insert plate passes through the middle of the first through hole and the heat-conducting ring and fits against the inner cavity wall of the first through hole and the heat-conducting ring.

[0010] Preferably, the high-power silicon-carbon supercapacitive battery and the separator are bonded together, and the separator, the positioning insert, and the connecting ear are made of the same material.

[0011] Preferably, the bottom wall of the high-power silicon-carbon supercapacitive battery is attached to the top wall of the heat-conducting plate, and the interior of the supporting base box is provided with coolant.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model first uses a partition to transfer and absorb the heat of the high-power silicon-carbon supercapacitor battery and introduce it into the middle of the positioning plate, thereby transferring it to the middle of the heat-conducting ring. Coolant is injected into the bottom box through the water inlet pipe, allowing the coolant to transfer heat with the heat-conducting ring. The coolant is then discharged to achieve the circulation of coolant, which can realize the heat transfer and dissipation, thus making the heat transfer more uniform. The heat-conducting plate transfers heat to the bottom of the high-power silicon-carbon supercapacitor battery, improving the heat transfer effect, thereby reducing the risk of thermal runaway and improving the overall safety.

[0014] 2. This utility model also allows for the uniform distribution of coolant entering the support base box and the uniform distribution of discharged coolant by setting up a partition plate and a second through hole, thereby improving the coolant's performance. Furthermore, by inserting a positioning plate into the first through hole, the installation position of the partition plate and the position of the high-power silicon-carbon supercapacitor battery can be further limited, thus improving the performance.

[0015] In summary, through the interaction of the above-mentioned multiple effects, the heat generated by high-power silicon-carbon supercapacitor batteries can be uniformly transferred and dissipated, improving the heat transfer effect, thereby reducing the risk of thermal runaway and improving overall safety.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] As attached Figure 1-3 The heat transfer device for the high-power silicon-carbon supercapacitor battery pack shown includes a supporting base box 1. A heat-conducting plate 2 is provided on the top wall of the supporting base box 1. The supporting base box 1 and the heat-conducting plate 2 support the battery pack composed of high-power silicon-carbon supercapacitor batteries 9 at the top. At the same time, the heat generated by the high-power silicon-carbon supercapacitor batteries 9 is absorbed and transferred to the middle of the supporting base box 1 through the heat-conducting plate 2, thereby realizing heat transfer. Multiple first through holes 3 are opened on the bottom wall of the heat-conducting plate 2 and the supporting base box 1. Multiple heat-conducting rings 4 are fixedly connected to the middle of the supporting base box 1. The partition plates 10 on both sides of the high-power silicon-carbon supercapacitor batteries 9 can be conveniently positioned through the first through holes 3 and the heat-conducting rings 4, and the heat of the partition plates 10 can be absorbed and transferred through the heat-conducting rings 4. The partition plates 5 are symmetrically fixedly connected to both sides of the inner cavity of the supporting base box 1. The surface of the partition plates 5 is opened with second through holes 6. The coolant entering the supporting base box 1 can be evenly distributed to the middle of the supporting base box 1 through the partition plates 5 and the second through holes 6.

[0024] The support base box 1 is connected to an inlet pipe 7 and an outlet pipe 8 on both sides. A high-power silicon-carbon supercapacitor battery 9 is installed on the top of the support base box 1. A partition 10 is installed on both sides of the high-power silicon-carbon supercapacitor battery 9. Multiple positioning plates 11 are fixedly connected to the bottom of the partition 10, and a connecting ear 12 is fixedly connected to the top of the partition 10. Coolant can be easily injected into the middle of the support base box 1 through the inlet pipe 7 and the outlet pipe 8, and can be easily discharged to realize the circulation of coolant and transfer heat to the battery pack at the top of the support base box 1 to achieve heat dissipation. The partition 10 separates the high-power silicon-carbon supercapacitor battery 9 and can transfer and cool the heat in the middle of the high-power silicon-carbon supercapacitor battery 9. The positioning plates 11 are inserted into the middle of the first through hole 3 and the heat conduction ring 4 to facilitate heat transfer to the partition 10 and to facilitate the positioning of the partition 10.

[0025] As attached Figure 1 , 2 As shown in Figure 5, the inlet pipe 7 and the outlet pipe 8 are respectively set on opposite sides of the two partition plates 5. Multiple heat-conducting rings 4 are set between the two partition plates 5. Coolant is injected into the interior of the support base box 1 through the inlet pipe 7 and temporarily stored through the partition plate 5. Then, it enters the middle of the support base box 1 evenly through the second through hole 6, so that the coolant is in contact with multiple heat-conducting rings 4, which facilitates heat transfer and makes the coolant discharge more even.

[0026] As attached Figure 2 , 3 As shown in Figures 4 and 5, the first through hole 3 and the heat-conducting ring 4 correspond one-to-one. The cross-sectional shape of the heat-conducting ring 4 is the same as that of the first through hole 3. The top wall of the heat-conducting ring 4 is fixedly connected to the bottom wall of the heat-conducting plate 2. The positioning insert 11 inserted into the middle of the first through hole 3 can penetrate the middle of the heat-conducting ring 4, and prevent the coolant from being discharged through the first through hole 3, thereby improving the performance.

[0027] As attached Figure 2 , 3 As shown in Figure 4, the size of the first through hole 3 is adapted to the positioning plate 11. The first through hole 3 and the positioning plate 11 correspond to each other. The positioning plate 11 passes through the middle of the first through hole 3 and the heat-conducting ring 4 and fits against the inner wall of the first through hole 3 and the heat-conducting ring 4. By passing through the middle of the first through hole 3 and the heat-conducting ring 4, the coolant can cool the positioning plate 11 when cooling the heat-conducting ring 4, thereby transferring the heat of the separator 10, cooling the high-power silicon-carbon supercapacitor battery 9, and simultaneously limiting the position of the separator 10.

[0028] As attached Figure 1 , 2As shown, the high-power silicon-carbon supercapacitor battery 9 and the separator 10 are attached together. The separator 10, the positioning insert 11 and the connecting ear 12 are made of the same material. The heat generated by the high-power silicon-carbon supercapacitor battery 9 is transferred through the separator 10 and is located in the middle of the positioning insert 11.

[0029] As attached Figure 1 , 2 As shown, the bottom wall of the high-power silicon-carbon supercapacitor battery 9 is attached to the top wall of the heat-conducting plate 2. The interior of the supporting base box 1 is filled with coolant. Through the attachment of the high-power silicon-carbon supercapacitor battery 9 and the heat-conducting plate 2, the heat generated by the high-power silicon-carbon supercapacitor battery 9 can be transferred through the bottom via the heat-conducting plate 2, thereby improving the performance.

[0030] The working principle of this utility model is as follows: When in use, the high-power silicon-carbon supercapacitor battery 9 is placed on the top of the support base box 1, and the separator 10 is located on both sides of the high-power silicon-carbon supercapacitor battery 9 and is in contact with the high-power silicon-carbon supercapacitor battery 9. At the same time, the positioning insert 11 at the bottom of the separator 10 is inserted into the middle of the first through hole 3 and is in contact with the wall of the first through hole 3 and the heat conduction ring 4.

[0031] Coolant is injected into the interior of the support base box 1 through the inlet pipe 7 and evenly enters the middle of the support base box 1 through the second through hole 6, and then discharged through the outlet pipe 8 on the other side, so that the coolant comes into contact with multiple heat-conducting rings 4.

[0032] When the high-power silicon-carbon supercapacitor battery 9 generates heat, the heat is transferred through the separator 10 and through the positioning insert 11 and the heat-conducting ring 4. The coolant transfers heat to the heat-conducting ring 4, thereby transferring the heat generated by the high-power silicon-carbon supercapacitor battery 9 to the middle of the coolant in the middle of the supporting base box 1, and then discharging it through the water outlet pipe 8, thus improving the performance.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
