Abstract
A cooling device is proposed that can be produced by the diecasting process, and which has a heat-transfer unit surrounded by an outer shell, wherein a jacket through which coolant flows is formed between the heat-transfer unit and the outer shell, said jacket is subdivided by webs in such a way that a passage through which coolant flows is formed between the outer shell and the outer casing of the heat-transfer unit. To this end, the webs are arranged in such a way that this circulating flow is effected in a meander shape. Compared with a spiral flow, this results in degrees of freedom with regard to the arrangement of the coolant inlets and coolant outlets. Furthermore, such cooling devices can be produced and assembled in a cost-effective manner and have a high efficiency.
