Title:
HEAT EXCHANGER AND METHOD FOR PRODUCING HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2011/136055
Kind Code:
A1
Abstract:
Disclosed is a heat exchanger that can maintain adhesion of a fin and a heat exchange pipe while ensuring the corrosion resistance of the heat exchange pipe. Further disclosed is a method for producing the heat exchanger. The heat exchanger is provided with a heat exchange pipe (4) and a plate-shaped fin (5) having a through-hole (5a) that the heat exchange pipe (4) penetrates; the plate-shaped fin (5) has a three-layered structure comprising: a core material layer (52) formed from an Al-Mn alloy; a brazing material layer (51) that configures one end surface and that is formed from an Al-Si alloy; and a sacrificial corrosion layer (53) that configures the other end surface and that is formed from an Al-Zn-Mg alloy; and the plate-shaped fin (5) is provided with a tubular section (5b) that rises at the periphery of the through-hole (5a) and that is the inner peripheral surface of the brazing material layer (51). Also, a plurality of plate-shaped fins (5) layered to the heat exchange pipe (4) are bonded to the heat exchange pipe (4) by brazing by means of the melting of the brazing material layer (51).
