Title:
CORROSION DETECTOR
Document Type and Number:
Japanese Patent JP2023131591
Kind Code:
A
Abstract:
To provide a corrosion detector capable of improving the corrosion detection accuracy of a heat exchanger.SOLUTION: A corrosion detector 30 detects corrosion of a heat exchanger 10 having a refrigerant flow tube composed of a metal material having aluminum or aluminum alloy as a base material. On the outer surface of the metal material, a sacrificial anticorrosion layer composed of zinc or an alloy containing zinc and aluminum is formed. The corrosion detector 30 includes a light emitting part 32, a light receiving part 33 and a determination part 34 which are detection parts for detecting corrosion products peeled from the surface of the refrigerant flow tube.SELECTED DRAWING: Figure 5
