POWER BATTERY PACK HAVING HEAT SUPERCONDUCTING HEAT EXCHANGER AND POWER BATTERY PACK SYSTEM

摘要

The present invention provides a power battery pack having a heat superconducting heat exchanger and a power battery pack system. The power battery pack comprises a heat superconducting heat exchanger and a plurality of battery cells. The heat superconducting heat exchanger comprises a heat radiator, a heater, and a plurality of heat superconducting plates arranged at intervals in parallel. The heater is located at one side of the heat radiator. The heat superconducting plates are located between the heat radiator and the heater, a heat superconducting pipeline is formed inside each heat superconducting plate, each heat superconducting pipeline is a closed pipeline, and each heat superconducting pipeline is filled with a heat transfer medium. The battery cells are located between the heat radiator and the heater, and each battery cell is in contact with the corresponding heat superconducting plate. According to the present invention, the battery cells can be quickly heated when the temperature of the battery cells is relatively low, so as to shorten the heating starting time of the battery cells at low temperature; in addition, the battery cells can be quickly cooled when the temperature of the battery cells is relatively high.
