Abstract
A method for producing a heat exchanger in which the heat exchanger has a plurality of identically embodied guide baffles which form a helical guide for the composition and which are penetrated by heat exchanger tubes. For making through openings in the guide baffles for the heat exchanger tubes, a mounting device cooperates with a laser beam device. By making the through openings in the guide baffles that have already been provided with their final slope, the through openings can be adapted very precisely to the heat exchanger tubes. As a result, losses from overflow of the composition at the guide baffles are reduced, and the efficiency of the heat exchanger is increased.
Claims20
A method for producing a heat exchanger which in a hollow-cylindrical housing jacket is closed off by end pieces and has a plurality of tubes for a heating medium, located parallel to one another, which extend parallel to the longitudinal axis of the housing jacket, and having a helical guide, located in the housing jacket, for the composition to be heated and cooled, the guide including a plurality of identically embodied guide elements that in at least some regions have portions, extending obliquely to the longitudinal axis of the housing jacket, in which portions through openings through which the tubes extend are embodied, the method comprising the steps of preshaping the guide elements in their at least nearly final form before the through openings are made and installing the preshaped guide elements in a mounting device, which cooperates with a device for creating the through openings.
