Abstract
A heat exchanger, a processing method of a heat exchanger and a composite material, wherein the heat exchanger includes a collecting pipe, a fin and a number of heat exchange tubes. Each of the heat exchange tubes is fixed to the collecting pipe, and an inner cavity of the heat exchange tube is communicated with an inner cavity of the collecting pipe. The fin is retained between two adjacent heat exchange tubes. The heat exchanger further includes a coating layer which is coated on an outer surface of at least one of the collecting pipe, the heat exchange tube and the fin. The coating layer includes micro-nano particles and a polymer obtained by polymerizing monomers including allylic monomers with hydrophilic groups. The micro-nano particles include silicon dioxide and/or titanium dioxide. The coating layer of the heat exchanger has excellent hydrophilic durability.
