HEAT SINK OF BATTERY CELL FOR ELECTRIC VEHICLES AND BATTERY CELL MODULE USING THE SAME

摘要

A heat sink of a battery cell for electric vehicles and a battery cell module using the heat sink are provided to prevent deterioration of battery cells by effectively emitting heat generated from the battery cells. The battery cells are arranged at predetermined intervals and connected in parallel or series to each other. Each of the heat sinks is arranged between the battery cells and radiates heat generated from the battery cells. Each heat sink includes a heat-radiating case attached to at least one side of each battery cell and filled with a first refrigerant, and a second refrigerant circulating pipe arranged in the heat-radiating case and configured to circulate a second refrigerant for cooling the first refrigerant. A first refrigerant filled in the heat-radiating case may also be circulated for a heat exchange.
