ABSTRACT:
A catalyst coating5for decomposing ozone in the air is applied to an outer surface of cooling pipes3and radiating fins4of a radiator2. A peel sensor2is provided on the catalyst coating5of the radiator2to detect a loss (remaining amount) of the catalyst coating5. The position of detection of the peel sensor2is determined according to a temperature characteristic of the radiator2, and a flow rate of the air passing through the radiator2. The position of detection of the peel sensor2can be determined easily and appropriately, such that loss and deterioration of the catalyst coating5can be detected with high precision.
