Zusammenfassung:	PCT No. PCT/EP91/00925 Sec. 371 Date Nov. 6, 1992 Sec. 102(e) Date Nov. 6, 1992 PCT Filed May 17, 1991 PCT Pub. No. WO91/18759 PCT Pub. Date Dec. 12, 1991.A motor vehicle battery cooling arrangement wherein the battery is enclosed by a housing which includes an air inlet port connected to an air guide disposed in front of the vehicle's radiator and cooling fan and an air outlet port connected to the outside. When the vehicle is moving, air impacting at the air guide enters the air inlet port and exits the air outlet port thus cooling the battery. When the vehicle is stationary or when it is very hot and the fan is turned on, the direction of air flow through the battery housing is reversed as the fan induced air flow at the air guide produces a partial vacuum which sucks hot air away from the battery housing through the air inlet port. Cooler fresh air is drawn into the battery housing through the air outlet port. In an alternate embodiment, the air inlet port is connected to the front portion of the engine compartment and the air outlet port is connected to the scoop or shroud housing for the cooling fan located behind the radiator. During fan operation, the partial vacuum which forms in the fan scoop draws hot air out from the battery housing via the air outlet port. In normal driving conditions, when the fan is not working, the normal flow of air impacts the front of the vehicle and forces air through the air inlet port to the battery housing and the air flow then exits through the air outlet port to the fan scoop and from there again reaches the outside.
