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, substantially cylindrical inner wall 2, wherein the water duct 5 extends along the outside of the inner wall 2 and the burner space 11 extends inside the inner wall 2, wherein, on the inside, the elements 6 increasing the heat-transferring area such as projections and/or partitions extend from the inner wall 2 in at least two directions which include an angle relative to each other, wherein the heat exchanger 1 has a substantially circular cross section and the elements 6 increasing the heat-transferring area are distributed over almost the entire inner circumference of the inner wall 2 in at least a part of the heat exchanger 1. <IMAGE>
