HEAT EXCHANGER
Document Type and Number:
Japanese Patent JP2016125698
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a heat exchanger capable of expressing at least one drug effect out of an anti-mold effect and an antibacterial effect effectively and persistently for a long period of time.SOLUTION: A heat exchanger comprises: a plurality of heat exchange fins (10); and heat transfer tubes assembled with the plurality of heat exchange fins (10). The heat exchange fins (10) are each provided with a base material (21) and a hydrophilic coat (23) formed on the base material (21). The hydrophilic coat (23) has at least one drug effect out of an anti-mold effect and an antibacterial effect, and includes a plurality of types of drug particles (30, 31, 32) different in the timing of expressing the drug effect. At least one type of the drug particle (31, 32) out of the plurality of types of the drug particles (30, 31, 32) is a drug particle (31, 32) having a surface covered with a capsule material (42, 43) that is slowly soluble in water.SELECTED DRAWING: Figure 2
