HEAT EXCHANGER FIN AND HEAT EXCHANGER USING HEAT EXCHANGER FIN

WIPO Patent Application WO/2015/058452

A1

A heat exchanger fin comprises several cooling fin units (402). Each of the cooling fin units (402) comprises a windward plate (410), a leeward plate (430), and a middle plate (420) located between the windward plate (410) and the leeward plate (430). On the heat exchanger fin, a first segment pitch boss (412) used for limiting a gap between the windward plates is bent and extends out. Projection of the first segment pitch boss (412) on a plane on which the windward plate (410) is located crosses a connection line of the windward plate and the middle plate or is located at one side of the connection line and adjacent to the connection line, so as to keep a predetermined distance between the heat exchanger fins to prevent the windward plates from bonding together when the heat exchanger is welded in a brazing furnace, and apply uniform force to each first segment pitch boss during bending of the heat exchanger, so as to reduce a situation that the first segment pitch boss is detached from the corresponding heat exchanger fin, so that gaps between the windward plates of the heat exchanger fin after the bending of the heat exchanger are uniform.
