Title:
HEAT EXCHANGER AND METHOD FOR HYDROPHILIZING HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2018/101355
Kind Code:
A1
Abstract:
The present invention provides a heat exchanger which is imparted with high deodorizing properties in terms of cigarettes. A heat exchanger which has a hydrophilic coating film on the surface of a substrate that is formed from aluminum, and wherein the hydrophilic coating film is formed using a hydrophilizing agent that contains 0.8-1.8% by mass of a vanadium compound (E) in terms of elemental vanadium, while containing 90% by mass or more of a resin (D) which contains 38-40% by mass of a polyvinyl alcohol (A) having an ethylene chain, 22-24% by mass of a radically polymerizable monomer (B1) having a carboxylic acid, 15-17% by mass of a radically polymerizable monomer (B2) represented by general formula (1) and 22-24% by mass of a polyethylene glycol (C).
