Abstract (en)
A heat exchanger, manufactured from light metal by means of casting technique, comprising at least a water duct, a burner space and elements increasing the heat-transferring area, wherein the heat exchanger (1) comprises a closed, polygonal or bent inner wall (2), wherein the water duct (5) extends spiral-wise along the outside of the inner wall (2) and the burner space (11) extends inside the inner wall (2), wherein at least in a portion of the heat exchanger on the inside, the elements (6) increasing the heat-transferring area such as projections and/or partitions extend from the inner wall (2), preferably in at least two directions that include an angle relative to each other. <IMAGE>
