Abstract
PURPOSE: To improve the corrosion resistance of a heat exchanger made of Al alloys by using an Al-Zn alloy for either one or both of pipe material and fin materials, and subjecting the same to Zn diffusion heat treatment after brazing by using Al-Si type brazing filler metals, in manufacturing said heat exchanger.
CONSTITUTION: Al or an Al alloy such as Al-Mn or an Al alloy contg. 0.2W2.0% Zn for the purpose of imparting pitting resistance is used as a pipe material. A clad material of a core material of Al, or an Al alloy such as Al-Mn, or an Al alloy contg. 0.5W3.0% Zn for the purpose of giving sacrifice anode effect and a brazing filler metal of an Al-Si type alloy is used as a fin material. Namely, the heat exchanger made by using the Zn-contg. Al alloy for either one or both of the pipe material and fin materials and brazing these at 580W650°C in a vacuum of 10-3W 10-6 torr is heated and held at 300W570°C in the atmosphere or an inert gas atmosphere of 10-1W1atm, whereby it is subjected to Zn diffusion heat treatment.
