Abstract (en)
[origin: DE102004061354B3] The method involves arranging a helical duct (25) within a housing (11), which is closed by end pieces (14, 15). Through-holes (28) are drilled in guide plates (26) using laser beams emitted from a laser device. The plates for guiding the mass to be heated or cooled are supported in the duct by a supporting unit (21). Pipes (23) for heat medium are inserted into the holes and are arranged parallel to a longitudinal axis of the housing. An independent claim is also included for a device for manufacturing a heat exchanger.
