Abstract
A processing method of a heat exchanger and a heat exchanger are provided. The processing method includes following steps. A heat exchanger and a composite material is provided, where the heat exchanger includes a collecting pipe, a fin and a heat exchange tubes. The heat exchange tube is fixed to the collecting pipe. An inner cavity of the heat exchange tube is communicated with an inner cavity of the collecting pipe. At least part of the fin is retained between two adjacent heat exchange tubes. The composite material includes a solvent and an organosilane-based modified material with low surface energy. The composite material is coated on at least part of an outer surface of at least one of the collecting pipe, the heat exchange tube and the fin, and the composite material is cured. The heat exchanger obtained according to the present disclosure shows better hydrophobic performance.
