<p>A battery cooling system for use with a vehicle 14 is disclosed including several batteries or battery modules 16 to 38 which provide power to the vehicle 12. The system includes a refrigerant gas channelling or conduit system which is effective to store, compress, expand and circulate refrigerant gas through the battery pack 12 and the system. A first "high pressure" conduit system, having several tubes or conduits that are disposed throughout the vehicle 14, is used to selectively carry and transport pressurized or compressed refrigerant gas to the battery pack 12 and includes a pump 42, a heat exchanger 44, expansion valves 46 - 52, and conduits 54, 56, 58, 60 and 62. A second "low pressure" conduit system is used to circulate the "expanded" or decompressed refrigerant gas throughout the battery pack 12 and to return the refrigerant gas to pump 42 for recompression. The low pressure conduit system includes conduits 64 to 78 which are in contact with one or more sides of the various battery modules 16 to 38 and which absorb and/or dissipate heat from battery modules 16 to 38, and conduits 80 to 84 which return the circulated refrigerant gas to pump 42.</p> |
