[0002] The battery discharge instrument is a device specially used for power, telecommunications, railways, battery production enterprises or other industries to maintain, detect the capacity and test the load capacity of direct current power supply of the battery pack. A large amount of heat is generated in the working process of the battery discharge instrument, so effective heat dissipation measures are needed to ensure the normal operation and safety of the device.

[0003] In the working process of the battery discharge instrument, the performance of the battery is tested through the discharge process. In this process, the current passes through the discharge instrument and the battery, and generates a certain amount of heat. Since the battery discharge instrument body is generally installed in the shell for protection, the shell is usually provided with a heat dissipation hole. However, the heat dissipation capacity of the heat dissipation hole is limited, especially in a high temperature environment, the internal heat may not be discharged in time and effectively through the heat dissipation hole only, which will cause the internal temperature of the device to gradually rise, affecting the normal operation and performance of the device, and the dust particles in the environment will also enter the shell through the heat dissipation hole, causing damage to the internal equipment.

[0004] Therefore, it is necessary to provide a portable battery discharge test device to solve the above technical problems. SUMMARY
