Abstract

PURPOSE:To improve the corrosion resistance by preventing the Zn evaporation of the bending part of a porous pipe in brazing the both after inserting a fin between Al alloy made meandering porous pipes by coating Zn thereon. CONSTITUTION:A porous pipe 3 is made by extruding an Al alloy made billet, the thermal spray of Zn or Al-Zn alloy is executed immediately after the extrusion of the porous pipe 3 and a coating layer is provided on the porous pipe 3 surface. Thereafter this porous pipe 3 is meanderingly bent and the fin 8 consisting of the material of lower potential than that of the porous pipe 3 material and to which a brazing filler metal is claded is inserted between the bent porous pipes 3. The material to be coated evaporation preventing plate 9 in the shape corresponding to the bending part and made of a stainless steel thin plate is superposed on the bending part. And these assembly bodies are held under the specified vacuum at the specific temp. and for specified time and the porous pipe 3 and fin 8 are joined to make the heat exchanger.
