Title:

FIN HEAT EXCHANGER FOR CLOTHES WASHING MACHINE OR CLOTHES DRYER, AND METHOD FOR MANUFACTURING SAME

Document Type and Number:

WIPO Patent Application WO/2017/129062

Kind Code:

A1

Abstract:

Provided are a fin heat exchanger for a clothes washing machine or a clothes dryer, and a method for manufacturing same, said fin heat exchanger (100) comprising a set of fins (101), and a heat exchange tube (102) interpenetrating the set of fins (101); a metal tube is bent multiple times and then folded at least once to form at least two columns of bent tubing, then the heat exchange tube (102) is inserted as a whole into the set of fins. In the heat exchanger, no damage resulting from a need for welding is caused to the heat exchange tube, thus the integrity of the heat exchange tube is protected; when a heat-exchange fluid flows through an integrated heat exchange tube, no impact damage is caused to the heat exchange tube as a result of a large fluid impact force, and no leaking of the fluid medium is caused by high-temperature fluid flowing into the heat exchange tube; the heat exchange performance of the heat exchange tube is guaranteed, and there is no problem of unevenness of the inside walls between the welded tube connection ends obstructing the flow of the fluid medium and thereby causing the heat exchanger to have low performance.
