Abstract
A catalyst coating 5 for decomposing ozone in the air is applied to an outer surface of cooling pipes 3 and radiating fins 4 of a radiator 2. A peel sensor 2 is provided on the catalyst coating 5 of the radiator 2 to detect a loss (remaining amount) of the catalyst coating 5. The position of detection of the peel sensor 2 is determined according to a temperature characteristic of the radiator 2, and a flow rate of the air passing through the radiator 2. The position of detection of the peel sensor 2 can be determined easily and appropriately, such that loss and deterioration of the catalyst coating 5 can be detected with high precision.
Claims5
A detector for a vehicle equipped with a heat exchanger, in which a catalyst coating provided in the heat exchanger decomposes a chemical substance in air passing through the heat exchanger, the detector comprising:
- a sensor that detects a remaining amount of the catalyst coating;
- and
- a control unit that generates an alarm based upon detection of the sensor, wherein a position of detection of the sensor is determined according to a temperature characteristic of the heat exchanger.
