Document Type and Number:
Japanese Patent JP2017009246
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a corrosion detection device of a heat exchanger capable of detecting the progress of corrosion of the heat exchanger.SOLUTION: A heat exchanger 6 includes a plurality of laminated fins 8, and a heat transfer tube 9 penetrating through the fins and composed of a metallic material of a kind different from the fins. The heat exchanger further includes metallic materials 20, 40 for electrically connecting the plurality of fins to each other, and a corrosion detection device 30 detecting a resistance value between at least any one of the fins and the metallic materials and the heat transfer tube, and detecting the progress of corrosion in the heat exchanger composed of the plurality of fins on the basis of the detected resistance value.SELECTED DRAWING: Figure 1
