METALLIC POROUS BODY INCORPORATED BY CASTING INTO A HEAT EXCHANGER

摘要

The present invention relates to a co-cast heat exchanger element intended for a central heating boiler, which heat exchanger element is made from substantially aluminum, the heat exchanger element being provided with walls which enclose a water carrying channel, and with at least one wall which encloses at least one flue gas draft to which a burner can be connected, at least one wall which encloses the at least one flue gas draft being water-cooled in that it also forms a boundary of the water-carrying channel, while one of the water-cooled walls is provided with heat exchanging surface enlarging pins and/or fins which extend in the respective flue gas draft and is also provided with other heat exchanging surface enlarging metallic porous structures.
