Brazing process for sealing strip type radiator

The invention relates to a brazing process for a sealing strip type radiator. The brazing process comprises the following steps that 1) core body parts are cleaned by using ultrasonic waves, and then are assembled into a core body; 2) welding flux powder and purified water are blended according to the proportion that the concentration of a welding flux is 16%-18% to obtain the welding flux; 3) the assembled core body is soaked in the prepared welding flux for 3 minutes, and it is guaranteed that all inner fins and outer fins have the welding flux; (4) the core body is taken out to blow off redundant welding flux on the surface of the core body; and (5) tunnel furnace brazing is carried out, no welding flux is left on the surface of the core body after brazing, and the appearance requirement the same as that of vacuum furnace brazing is met. According to the brazing process for the sealing strip type radiator, through the process improvement, the welding flux left on the surface of the tunnel furnace brazing s
