[0037] like Figures 1 to 8 As shown, this embodiment provides a commercial vehicle battery temperature control system, which includes: a shell 1, a support frame 2 and several heat-conducting components. The shell 1 is provided with a accommodating cavity, and the support frame 2 is placed in the accommodating cavity. The support frame 2 includes several carrying units arranged in a vertical direction, each carrying unit is used to accommodate a battery pack 3, and the several heat-conducting components are arranged in a one-to-one correspondence with the several carrying units. The heat-conducting components include multiple heat-conducting pipes 4, and the multiple heat-conducting pipes 4 are arranged at intervals and supported on the carrying units. The outer side of the battery pack 3 is covered with a first thermal insulation layer 5, and the multiple heat-conducting pipes 4 are arranged between the first thermal insulation layer 5 and the bottom of the battery pack 3. The heat-conducting pipes 4 have ventilation holes 6 connected to the outside air at both ends along their own length direction, and a removable cover 7 is provided at the ventilation hole 6. With this arrangement, when the ambient temperature is high, the blocking cover 7 can be removed to open the ventilation hole 6, and the heat pipe 4 is in direct contact with the battery pack 3, absorbing the heat from the outer surface of the battery pack 3 and transferring it to the tube wall of the heat pipe 4, and radiating the heat to the external air through the ventilation airflow for rapid heat exchange, thereby achieving dynamic thermal regulation. When the ambient temperature is low, the blocking cover 7 can be fastened to close the ventilation hole 6, blocking the ventilation of the heat pipe 4 from the outside, and cooperating with the covering of the first thermal insulation layer 5 to reduce the heat conduction of the battery pack 3 to the external environment, thereby achieving sealing and insulation of the battery. It can adjust the temperature of the battery pack 3 in real time according to the ambient temperature and the status of the battery pack 3, ensuring that the battery pack 3 is always within the optimal operating temperature range, thereby improving the performance of the battery pack 3, extending the cruising range, and ensuring the safety and reliability of the vehicle.

Both the first flange 13 and the second flange 14 are fan-shaped, and the inner sides of the first flange 13 and the inner sides of the second flange 14 can be in contact with the outer wall of the housing 1.
