Heat exchanger, comprising a heat exchanger body made of light metal or light metal alloy, wherein the body comprises at least a flue duct and a flame receiving space, wherein the body comprises two parts at opposite sides of the flue duct and flame receiving space, said two parts substantially defining said flue duct and flame receiving space, wherein the flue duct and flame receiving space define a main flow direction for flue gas between an entry side of the flame receiving space and an outlet of the flue duct, wherein each of said parts comprises a first series of ribs extending into the space between said two parts and having a length direction substantially perpendicular to the main flow direction for flue gas, thus defining a meandering flow path of flue gasses between said flame receiving space and said outlet and a second series of ribs extending in said flame receiving space, wherein between the ribs of said second series of opposite parts an open space is provided.
Heat exchanger, comprising a heat exchanger body made of light metal or light metal alloy, wherein the body comprises at least a flue duct and a flame receiving space, wherein the body comprises two parts at opposite sides of the flue duct and flame receiving space, said two parts substantially defining said flue duct and flame receiving space, wherein the flue duct and flame receiving space define a main flow direction for flue gas between an entry side of the flame receiving space and an outlet of the flue duct, wherein each of said parts comprises a first series of ribs extending into the space between said two parts and having a length direction substantially perpendicular to the main flow direction for flue gas, thus defining a meandering flow path of flue gasses between said flame receiving space and said outlet and a second series of ribs extending in said flame receiving space, wherein between the ribs of said second series of opposite parts an open space is provided.
Method for forming a heat exchanger body, wherein two parts are formed by extrusion, each having an inner wall from which parallel ribs extend, which parts are positioned with the inner surfaces facing each other and are connected by end parts, such that said two parts substantially define a flue duct and a flame receiving space opening into said flue duct, wherein the flue duct and flame receiving space define a main flow direction for flue gas between an entry side of the flame receiving space and an outlet of the flue duct substantially perpendicular to an extrusion direction of the parts, preferably such that the ribs define a meandering flow path of flue gasses between said flame receiving space and said outlet, and wherein between the ribs of said opposite parts in the flame receiving space an open space is provided.
