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

A method for plugging a hole, particularly a hole provided in a cooling element, in which method a hole formed in a piece essentially made of mainly copper, for instance in the housing element of a cooling element, there is arranged a plug mainly made of copper. Between the side surface of the plug...

Zusammenfassung:	A method for plugging a hole, particularly a hole provided in a cooling element, in which method a hole formed in a piece essentially made of mainly copper, for instance in the housing element of a cooling element, there is arranged a plug mainly made of copper. Between the side surface of the plug and the inner surface of the hole, there is arranged brazing agent with a melting temperature lower than that of the pieces to be joined together, and the junction area between the plug and the piece, such as the housing element 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.
