Heat exchanger for heat transfer between two circulation systems, e.g. from heating system to service water, with first circulation system form from tubing network and second circulation system formed from rolled up plate

摘要

The first circulation system (10) is made from a tubing network (11), whereby the primary medium flows in the inner network. The second circulation system (20) is formed from a plate (21), which is spirally rolled up, whereby the secondary medium flows between the plate coil parallel to the spiral axle. The tubing network is thermally connected to the rolled up plate at one side, and is jointly rolled up with the plate.
