Title:
HEAT EXCHANGER AND PROCESSING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/024743
Kind Code:
A1
Abstract:
The present application provides a processing method for a heat exchanger and a heat exchanger. The processing method for a heat exchanger comprises the following steps: providing a heat exchanger, the heat exchanger comprising a manifold, a fin and a plurality of heat exchange pipes fixed together, inner cavities of the heat exchange pipes communicating with an inner cavity of the manifold, and the fin being fixedly connected between two adjacent heat exchange pipes; and performing sandblasting on the heat exchanger, so that a rough surface is formed on at least a part of an outer surface of a metal substrate corresponding to at least one among the manifold, the fin, or the heat exchange pipes. Sandblasting is beneficial for removing attached impurities on the outer surface of the metal substrate and reducing the dangerousness and pollution of the process; meanwhile, the rough surface formed after passing through sandblasting is beneficial for improving the adhesive ability of the metal substrate of the heat exchanger to bind with other coating materials.
