Title:
CORROSION DETECTION SENSOR, COOLING APPARATUS, COOLING SYSTEM, AND VEHICLE POWER SUPPLY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/158830
Kind Code:
A1
Abstract:
The corrosion detection sensor 7 according to the present invention is used in a heat exchange apparatus in which a portion of a channel through which a heat transfer medium flows is sealed with a seal member 22. The corrosion detection sensor 7 according to the present invention is provided with: a sensor portion having a sensing electrode 10 and a counter electrode 11 each of which is in contact with the heat transfer medium through the seal member 22, and an alternating-current power supply 12 that applies an alternating-current voltage between the sensing electrode 10 and the counter electrode 11; and a control unit that detects corrosion in the channel on the basis of a change in impedance that occurs when the alternating-current voltage is applied between the sensing electrode 10 and the counter electrode 11. The corrosion detection sensor 7 according to the present invention is able to detect corrosion of a part that may lead to leakage of the heat transfer medium accurately and at an early stage to prevent leakage of the heat transfer medium, without the need to increase the size of the heat exchange apparatus or to introduce a complicated design.
