<p>The present invention relates to a method for brazing pipes of an evaporator for the refrigeration. The linear both ends of the pipes in which a heat radiation pin is brazed in an outer periphery is brazed with a U band and a coupling end part is formed on the both side of the pipes. The U band is fixated by the pipes and a metal filler by being inserted to the coupling end part with the metal filler. In addition, the U band is brazed by melting brazing flux to be applied to the pipe in the nitrogen atmosphere, thereby enabling to braze the U band on the pipe easily and firmly.</p> |
