[0023] like Figure 1-3 As shown, the utility model provides a heat dissipation device for battery cell detection, including a heat conducting plate 1, a shell 2 is provided on the lower surface of the heat conducting plate 1, air outlets 201 are symmetrically opened on both sides of the shell 2, and a first heat dissipation component 4 is provided inside the shell 2;

[0024] The first heat dissipation component 4 includes a heat conducting sheet A403 connected to the bottom surface of the heat conducting plate 1, a heat dissipation fin 402 is arranged on the bottom surface of the heat conducting sheet A403, and a heat conducting sheet B404 is connected to the bottom surface of the heat dissipation fin 402, a semiconductor cooling sheet 405 is arranged on the bottom surface of the heat conducting sheet B404, and the cooling end of the semiconductor cooling sheet 405 is in contact with the bottom surface of the heat conducting sheet B404, a liquid storage tank 401 is arranged at the bottom of the shell 2, and flow guide pipes 406 are connected to both sides of the liquid storage tank 401, and the flow guide pipes 406 are arranged to penetrate the heat dissipation fins 402, and the part of the flow guide pipe 406 located in the heat dissipation fins 402 is arranged in an S shape;

[0025] The heat dissipation end of the semiconductor refrigeration sheet 405 is provided with a second heat dissipation component 3, and the effect is that when in use, the heat conduction plate 1 of the device is connected to the heating end of the battery cell detection equipment. When the battery cell detection equipment generates heat, the heat is transferred to the heat conduction sheet A403 through the heat plate, and the heat conduction sheet A403 transfers the heat to the heat dissipation fin 402, and the heat dissipation fin 402 transfers the heat to the heat conduction sheet B404. Then the semiconductor refrigeration sheet 405 is controlled to work, so that the cooling end of the semiconductor refrigeration sheet 405 cools and dissipates heat for the heat conduction sheet B404, and at the same time, the circulation of the coolant in the liquid storage tank 401 is controlled, so that the coolant circulates along the guide tube 406, thereby further dissipating the heat for the heat dissipation fin 402. By setting the first heat dissipation component 4, the heat dissipation area of ​​the device can be increased, the heat transfer rate can be improved, and the temperature of the heat dissipation fin 402 can be further reduced by setting the semiconductor refrigeration sheet 405, thereby improving the heat dissipation efficiency.

[0026] The second heat dissipation component 3 includes a fan A301 arranged below the heat dissipation end of the semiconductor cooling plate 405, and an air duct 302 is connected below the fan A301. The air duct 302 has two air outlet ends, and the air outlet ends of the air duct 302 are correspondingly connected to the air outlet 201. The side wall of the shell 2 is located at the position of the air outlet 201 and is provided with a fan B303. When in use, start the fan A301, and the airflow generated by the fan A301 drives the heat generated by the heat dissipation end of the semiconductor cooling plate 405 to flow. At the same time, start the fan B303, and the fan B303 accelerates the discharge of the hot air in the air duct 302 to the outside. Through the second heat dissipation component 3, the heat emitted by the semiconductor cooling plate 405 can be quickly discharged, thereby accelerating the heat dissipation process and improving the cooling efficiency.

[0027] A guide block 5 is arranged at the center of the inner bottom surface of the air guide duct 302, and the guide block 5 is an acute triangle. The guide block 5 is arranged to effectively guide and control the air flow direction, so that the hot air exhausted by the fan A301 can flow outward from the two air outlets 201 evenly, thereby accelerating the dissipation of heat and improving the heat dissipation effect.

[0028] A filter A304 is provided at the top of the air duct 302, and a filter B305 is provided on the outside of the fan B303 at the air outlet 201. The filter A304 and the filter B305 are provided to reduce dust from entering the fan, avoid clogging the air duct, and improve the heat dissipation efficiency and stability of the fan.

[0030] A liquid filling port 407 is provided on one side of the liquid storage tank 401 , and the cooling liquid inside the liquid storage tank 401 can be easily replaced through the provided liquid filling port 407 , thereby ensuring that the cooling liquid effectively dissipates heat for the device.

[0031] Working principle: When in use, connect the heat conducting plate 1 of the device to the heating end of the battery cell detection device. When the battery cell detection device generates heat, the heat is transferred to the heat conducting sheet A403 through the heat conducting plate 1. The heat conducting sheet A403 transfers the heat to the heat dissipating fin 402. The heat dissipating fin 402 transfers the heat to the heat conducting sheet B404. Then, the semiconductor refrigeration sheet 405 is controlled to work, so that the cooling end of the semiconductor refrigeration sheet 405 cools down and dissipates the heat of the heat conducting sheet B404. At the same time, the circulation of the coolant in the liquid storage tank 401 is controlled, so that the coolant circulates along the guide pipe 406, thereby further radiating the heat to the heat dissipating fin 402. In the first step of heat dissipation, fan A301 is started at the same time. The airflow generated by fan A301 drives the heat generated at the heat dissipation end of the semiconductor refrigeration plate 405 to flow. Under the diversion effect of the guide block 5, the air in the air duct 302 flows to the air outlets 201 at both ends. Then fan B303 is started. Fan B303 accelerates the hot air in the air duct 302 to be discharged outward from the air outlet 201. The combined heat dissipation of the first heat dissipation component 4 and the second heat dissipation component 3 increases the heat dissipation area of ​​the device, improves the heat transfer rate, and thus improves the heat dissipation efficiency of the device to the battery cell detection equipment, thereby ensuring the detection effect of the battery cell detection equipment.
