Liquid cooler for power semiconductor components

摘要

Each pipe (2) contains a torsionally fixed spiral (3) whose outer dimension of turns is the same as the inner contour of the pipes. Each spiral is longer than the pipes formed in the cooler body (1). The spiral is made of wire of the same material as the cooler body, with wire thickness amounting to 20 to 30 per cent of the spiral diameter. The spiral turns are equidistant with spacing equaling to the spiral diameter.
