Abstract: A condenser has an outlet side region close to an outlet for discharging refrigerant from the condenser. The outlet side region does not face auxiliary radiator, which is disposed on a cooling air upstream side of the condenser. Accordingly, low temperature cooling air that does not pass through the auxiliary radiator can flow into the outlet side region of the condenser in which the refrigerant is lowered most. As a result, a difference in temperature between the refrigerant and the cooling air at the outlet side region becomes large. This prevents deterioration of cooling capacity of the condenser.

Abstract: A vehicle-use battery cooling system for cooling a battery mounted in a vehicle whose vehicle compartment is air conditioned by an air conditioner, so as to maintain the battery in a predetermined temperature range, includes: a battery chamber for accommodating the battery; a cooling device having a cooling fan and adapted to cool the battery by supplying air in the vehicle compartment to an interior of the battery chamber by the cooling fan; a cooling-air circulating device for circulating air used in cooling the battery between the battery chamber and the vehicle compartment by guiding the air into the vehicle compartment; an exhausting device for exhausting the air used in cooling the battery to outside the vehicle; a changeover device for effecting a changeover between the cooling-air circulating device and the exhausting device; a temperature detecting device for detecting at least one of a temperature of the interior of the battery chamber and a temperature of the battery; and a changeover controlling d

Abstract: An automotive vehicle engine having a coolant circulation system with a radiator, a fan, and a thermostatic valve for controlling coolant flow through the radiator. This thermostatic valve starts to open at a first temperature, is fully opened at a second temperature, and is partly opened at an intermediate third temperature. A system for coupling the fan to a rotation engine member includes: a first member rotationally coupled to the rotating member; a second member rotationally coupled to the fan; and a mechanism for providing rotational coupling between the first and second members. The degree of rotational coupling is lower when a first control valve is closed than opened, and is lower when a second control valve is closed than opened.
