Abstract
A method for manufacturing a cooling element comprising a housing part and ceramic lining elements arranged on the housing part surface. The ceramic lining elements (2) are connected to the element housing part (1) by using in the joint between the lining elements and the housing part a soldering/brazing agent, wherein at least the junction area is heated at least up to the melting temperature of the soldering/brazing agent, so that there is created a joint with a good thermal contact with the element housing part (1) and a ceramic lining element (2). The invention also relates to a cooling element.

A method for manufacturing a cooling element comprising a housing part and ceramic lining elements arranged on the housing part surface, the method comprising connecting the ceramic lining elements to the element housing part, mainly made of copper, by using in the joint between the lining elements and the housing part a soldering agent, heating at least the junction area at least up to the melting temperature of the soldering agent, so that there is created a joint with a good thermal contact with the element housing part and a ceramic lining element and providing the surface of the cooling element housing part with grooves, in which the ceramic lining elements are fitted.
A cooling element comprising a housing part provided with a channel system for the cooling water circulation, and a lining made of ceramic elements in at least part of the housing part surface, comprising the ceramic lining elements being connected to the housing part, mainly made of copper, by means of a soldering agent having a melting temperature between 400° C. and 700° C. in a way that results in a good thermal contact between the ceramic element and the housing part, the surface of the cooling element housing part having grooves therein, in which the ceramic lining elements are arranged to be fitted.
