In a heat exchanger () for transferring heat from a first fluid to a second fluid, which heat exchanger () comprises one or more flow passages () for a first fluid, the outer wall () of these passages is in heat-transferring contact with a flow body () made from metal foam for a second fluid. This metal foam has a gradient of the volume density of the metal, so that it is possible to achieve a favorable equilibrium between heat transfer and conduction, on the one hand, and flow resistance, on the other hand.

Methods for the production of a board () with printed circuit () shielded against interfering radiation and having electronic components () comprise the steps of positioning of the electronic components () on contact points () designed for them, and the application of a shield (), comprising a preformed metallized plastic film () over the top of the electronic components () and in electrical contact with the earth () on the board () with printed circuit (), and also fixing the electronic components () on the board () with printed circuit () by means of an electrically conducting fixing agent (); and fixing of the shield () on the board () with printed circuit ().

Methods of manufacturing a printed circuit board shielded against interfering radiation

A gasket which shields against interfering radiation and comprises a metallized plastic foam has a network of open cells which are in communication with one another and is used, for example, to seal any gap between an earth wire on a PCB and cover which shields against interfering radiation. According to one aspect, the cells () are oriented in the height direction of the gasket in such a manner that the elastic compressibility of the gasket is at least 80% in the height direction.
