Battery temperature control device

The invention belongs to the field of temperature control devices, and particularly relates to a battery temperature control device which comprises a shell and a device main body. The device main body is arranged in the shell, and a heat dissipation mechanism is arranged at the bottom end of the shell; the heat dissipation mechanism comprises heat dissipation fins, heat conduction blocks, limiting cavities, limiting springs, limiting blocks and fixing assemblies, the heat dissipation fins are tightly attached to the bottom end of the shell, the heat conduction blocks are arranged at the top ends of the heat dissipation fins, the limiting cavities are formed in the two sides of the bottom end of the shell, the limiting springs are arranged in the limiting cavities, one sides of the limiting blocks are arranged in the limiting springs in a sleeved mode, and the fixing assemblies are arranged in the limiting blocks. And through the heat dissipation mechanism, the heat dissipation capability of the device is enha
