Document Type and Number:
Japanese Patent JP2012092735
Kind Code:
A
Abstract:

To provide an auxiliary device for an in-vehicle heat exchanger capable of satisfactorily alleviating fuel consumption caused by a generator load by improving efficiency of a heat exchanger.

The auxiliary device 1 for an in-vehicle heat exchanger includes: a switching valve 12 (switching means) provided halfway along a rainwater drainage path 11; a windshield wiper SW31 and rain sensor 32 (rainfall sensing means) for sensing rainfall; a pump 15 (spraying means) for spraying rainwater stored in a water storage tank 13 toward a radiator 2 and intercooler 3 (heat exchanger); and a microcomputer 25 (vehicle condition information acquiring means, switch control means, spray control means). The microcomputer 25 turns the switching valve 12 from a switching position for drainage to a switching position for water supply when rainfall is sensed by the windshield wiper SW31, etc. Further, the microcomputer 25 drives the pump 15 according to the acquired vehicle condition information.
