Thermal management system and thermal management method of base station

The invention discloses a thermal management system and thermal management method of a base station. In the thermal management system of the base station, all base station equipment containing batteries are arranged in an equipment cabinet to fabricate an integrated structure, a few amount of gas in the equipment cabinet is only needed to be refrigerated by an air conditioner during normal working, and electric energy is saved; the system can switch among three modes according to different working conditions, a phenomenon that the air conditioner continuously runs for all year round is prevented, relevant equipment of the air conditioner is difficult to damage, and the manual cost required for maintenance on a part is greatly reduced; a temperature control device is arranged in a battery cabinet, auxiliary temperature regulation can be performed according to application requirement of the batteries, and the batteries are enabled to normally run; and the temperature control device in the equipment cabinet can
