METHOD FOR PRODUCING A COOLING ELEMENT, AND A COOLING ELEMENT

摘要

A method for manufacturing cooling elements for power electronic components and other cooling devices for electric appliances, wherein molten metal is fed into a closed mould comprising a core part (10) and a mould part, the metal being allowed to become solid whereafter the finished casting is removed from the mould. An insert package (2) is assembled of lamellas (5) made from a material which at least essentially corresponds to the casting material by pressing together several lamellas (5) arranged next to one another such that an air slot remains between the lamellas. This insert package (2) is machined such that it fits into a recess (11) in the core part (10) and at least one machined surface of the package (2) forms a sealed joint between the core part (10) and the insert and the insert package (2) is placed in the recess (11) in the core part before closing the mould, whereby the package is fastened to the casting once the mould has been filled.
