  • Method for the manufacture of a heat-exchanger having at least one curved tube of flat cross-section
    Patent number: 4505419
    Abstract: A method for manufacturing a heat exchanger using a non-eutectic solder which melts over a melting range is disclosed. The soldering is carried out in two successive soldering steps, first at a soldering temperature which is at the lower end of the melting range, and then at a higher soldering temperature within the same range. Flat plates and straight-edge strips are used for the first soldering step. The straight tube of flat cross section produced in this manner is then curved in the desired fashion and soldered in final manner by the second soldering step.
