METHOD FOR PLUGGING A HOLE AND A COOLING ELEMENT MANUFACTURED BY SAID METHOD

摘要

A method for plugging a hole, particularly a hole provided in a cooling element, in which method in a hole (9) formed in a piece essentially made of mainly copper, for instance in the housing element (2) of a cooling element (1), there is arranged a plug (8) mainly made of copper. Between the side surface (11) of the plug (8) and the inner surface (13) of the hole, there is arranged brazing agent (10) with a melting temperature lower than that of the pieces to be joined together, and the junction area between the plug (8) and the piece, such as the housing element (2) of the cooling element, is heated at least up to the melting temperature of the brazing agent or to the vicinity thereof, whereafter the junction area is cooled. The invention also relates to a cooling element manufactured according to said method.
