摘要:
The invention provides a fluid cooling system comprising a heat exchanger (1) with an outer wall (2) forming a chamber with an inlet (3) and an outlet (4) for circulating a heat exchange medium in the chamber. The chamber has an opening towards the component which is to be cooled, and to protect the component, the opening is closed by a flexible wall (5) which is attached to the outer wall. To protect the cover and the component against overload, the flexible wall (5) is attached to an inner wall (7) inside the chamber. The cooling system could be applied to electronic systems, e.g. for cooling a DCB substrate or similar electronic components.

摘要:
A power semiconductor contact structure for power semiconductor modules, which has at least one substrate (1) and a metal moulded body (2) as an electrode, which are sintered one on top of the other by means of a substantially uninterrupted sintering layer (3a) with regions of varying thickness. The metal moulded body (2) takes the form here of a flexible contacting film (5) of such a thickness that this contacting film is sintered with its side (4) facing the sintering layer (3a) onto the regions of varying thickness of the sintering layer substantially over the full surface area. A description is also given of a method for forming a power semiconductor contact structure in a power semiconductor module that has a substrate and a metal moulded body. The forming of the power semiconductor contact structure is performed firstly by applying a layer of sintering material of locally varying thickness to either the metal moulded body (2) or the substrate, followed by sintering together the contacting film (5) with the substrate (1) by using the properties of the layer of sintering material that are conductive to connection, the contacting film (5) being made to develop its distinct form to correspond to the varying thickness of the layer of sintering material (3a).
