Air cooling device for motor vehicle, has additional cooling circuit including conduits and pump to circulate water received in reservoir via heat exchanger, and spray line extending closer to lower end of evaporator of main cooling circuit

摘要

The device has a main cooling circuit (2) in which a refrigerant circulates in a closed loop and including an evaporator (4) cooling a pulsated air. An additional cooling circuit (12) has conduits (16, 18) and a pump (20) for circulating the water received in a reservoir (6) through a heat exchanger (14). A spray line (22) of the circuit (12) extends closer to a lower end of the evaporator.
