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.

[0019] A battery temperature control device, as described above Figure 1 and Figure 3 The system includes a housing 1, a sealing block 2 on its side wall, and a square groove 11 formed on the side wall of the housing 1 at the corresponding position of the sealing block 2. Simultaneously, a through groove 13 is formed on the outer side wall of the sealing block 2, and the sealing block 2 has a hollow interior forming an installation groove 12. This installation groove 12 communicates with the internal area through the square groove 11 and with the external area through the through groove 13. (Continuing with...) Figure 3 and combined Figure 5 A crossbar 18 is fixedly mounted on the inner wall of the mounting groove 12. The crossbar 18 extends along the length direction of the mounting groove 12 (i.e., the length direction of the housing 1), and a return spring 19 is sleeved on the outer wall of the crossbar 18. The outer wall of the return spring 19 abuts against a connecting frame 23. The connecting frame 23 is provided with a through hole for the crossbar 18 to pass through and slide. (Refer to...) Figure 5 A connecting rod 22 is fixedly mounted on the outer wall of the connecting frame 23. A sealing plug 9 is fixedly mounted on the end of the connecting rod 22 away from the connecting frame 23. An electrode rod 20 is fixedly mounted on the top wall of the sealing plug 9. An electrode rod 21 is fixedly mounted on the top wall of the through groove 13.

[0020] Reference Figure 2 and Figure 4The top of the aforementioned housing 1 is fixedly fitted with a box body 3. The box body 3 is provided with a partition 16 extending along the cross section. The partition 16 divides the internal section of the box body 3 in the length direction, and correspondingly forms a cooling water chamber containing cooling water and a cooling liquid chamber containing coolant. Further, the cooling liquid chamber is provided with a plurality of copper plates 24 extending along the cross section of the box body 3, and the plurality of copper plates 24 are spaced apart along the length direction of the box body 3. At the same time, the cooling water chamber is provided with a water pump 15. The output port of the water pump 15 is fixedly sleeved with a copper pipe 10. The end of the copper pipe 10 away from the water pump 15 passes through the cooling liquid chamber and enters the cooling water chamber. The outer wall of the copper pipe 10 overlaps with the battery body 17.

[0021] Reference Figure 4 The top of the aforementioned housing 3 is fixedly fitted with a protective box 5, the outer wall of the protective box 5 is fixedly fitted with a storage battery 4, the outer wall of the protective box 5 is penetrated by an air supply pipe 6, the end of the air supply pipe 6 is equipped with a thermal generator 14, the top of the housing 1 is equipped with a fan 7, the outer wall of the housing 1 is rotatably connected with a power supply door 8, and the outer wall of the housing 1 is fixedly fitted with a controller 25.

[0022] In the above structure, the housing 1, sealing block 2, box 3, square groove 11, mounting groove 12, through groove 13, electrode rod 1 20, electrode rod 21, connecting rod 22, and connecting frame 23 are designed so that during use, when the battery body 17 heats up due to prolonged operation, the internal temperature of the housing 1 rises rapidly, causing the air to expand and increase in temperature. At this high temperature, electrode rod 1 20 will contact electrode rod 21, causing the controller 25 to automatically operate the water pump 15. This, in conjunction with the fan 7, provides both water and air cooling to the battery body 17, reducing the risk of the battery body 17 burning out or even exploding due to overheating. Furthermore, the controller 25 automatically operates the water pump based on whether electrode rod 1 20 contacts electrode rod 21, achieving simultaneous cooling of the battery body through both water and air methods. This improves the temperature control performance of the device, and the automatic operation eliminates the need for manual operation, enhancing the device's automation and intelligence.

[0023] In a preferred embodiment: the interior of the housing 3 is connected to the interior of the protective housing 5 through the air supply pipe 6, and one end of the air supply pipe 6 located on the inner wall of the housing 3 is 2cm above the coolant. The thermal generator 14 is electrically connected to the battery 4.

[0024] In the above structure, through the air supply pipe 6, when the copper pipe 10 circulates the cooling water, the contact between the copper pipe 10 and the copper plate 24 causes the coolant inside the box 3 to be heated and evaporated, thereby generating heat energy. The air supply pipe 6 can then conduct the heat energy to the heat generator 14, thereby achieving the effect of generating power through the heat generator 14, thus playing the role of heat energy recovery and power generation, and improving the energy utilization rate of the device.

[0025] In the above structure, through the copper pipe 10 and copper plate 24, when the copper pipe 10 circulates to accelerate the heat dissipation of the battery body 17, the copper pipe 10 can fully contact the copper plate 24, so that the heat in the cooling water can be dissipated in time, and the coolant evaporates to form a condensation effect. This can not only achieve the effect of heat dissipation of the cooling water, but also ensure that the thermal generator 14 has sufficient thermal energy for power generation.

[0026] In a preferred embodiment, electrode rod 20 and electrode rod 21 are electrically connected to battery 4 and controller 25, respectively, and controller 25 is electrically connected to battery 4.

[0027] In the above structure, the battery 4 and controller 25 are configured to store the generated electrical energy when the thermal generator 14 is working, thereby providing energy to the internal electronic components of the device and ensuring the normal operation of the device. The controller 25 can automatically control the water pump 15 to operate after the electrode rod 1 20 and the electrode rod 21 come into contact, ensuring that the internal temperature environment of the device can be adjusted in a timely manner, thereby improving the heat dissipation effect of the device on the battery body 17.

[0028] In a preferred embodiment: the outer wall of the sealing block 2 is fixedly assembled with the inner wall of the square groove 11, and the inner wall of the mounting groove 12 is slidably connected with the outer wall of the connecting frame 23.

[0029] In the above structure, through the sealing block 2 and the mounting groove 12, when the internal temperature of the housing 1 rises and causes the gas to expand and contract due to thermal expansion and contraction, the sealing plug 9 can slide along the inner wall of the through groove 13, thereby allowing the inside of the housing 1 to communicate with the outside through the sealing block 2. This ensures that the hot air inside the housing 1 can be discharged to the outside of the housing 1 through the sealing block 2, thus avoiding the risk of excessive heat accumulation leading to an explosion of the battery body 17 and the device, and improving the safety of the device during use.

[0030] In a preferred embodiment, the sealing plug 9 is made of rubber, and the outer wall of the sealing plug 9 is in close contact with the inner wall of the through groove 13.

[0031] In the above structure, the rubber material has the characteristics of elasticity and wear resistance, which can effectively reduce the wear of the sealing plug 9 during operation, thereby extending the service life of the sealing plug 9. The elasticity of the material can effectively ensure the sealing effect of the sealing plug 9 on the sealing block 2 and the shell 1, thereby avoiding the situation where high temperature air leakage prevents the electrode rod 20 and the electrode rod 21 from contacting, thus ensuring that the device can operate normally.

[0032] Working principle: After the user installs the device, the battery body 17 will generate heat during operation. At this time, the fan 7 can be used to assist in heat dissipation. After long-term operation, the heat gradually increases, causing the sealing plug 9 to be moved by the hot air. This allows the electrode rod 1 20 to contact the electrode rod 21. The controller 25 automatically controls the water pump 15 to operate, thereby realizing both air cooling and water cooling to accelerate the heat dissipation of the battery body 17. At the same time, during the circulation of cooling water inside the copper pipe 10, the contact between the copper pipe 10 and the copper plate 24 will allow the copper plate 24 to quickly absorb heat, thereby causing the coolant to evaporate and form condensation, thus generating high-temperature air. The high-temperature air is sent to the heat generator 14 through the air supply pipe 6, thereby realizing the effect of the heat generator 14 generating electricity through heat, improving the energy utilization rate of the device.
