Title: HEAT EXCHANGER
Abstract:
A heat exchanger comprises a heat exchanger body made of light metal or light metal alloy. The body comprises a combustion chamber and a flue gas duct. The flue gas duct is provided for the flow of flue gas generated in the combustion chamber. The body comprises two walls at opposing sides of the flue gas duct. Each of the two walls comprises at least one flow channel for a liquid to be heated via heat transfer from the flue gas. Each of the two walls comprises pins, fins or ribs extending into the flue gas duct. The heat exchanger comprises an insert object provided in the flue gas duct. The insert object is an elongated object. The insert object makes contact with pins, fins or ribs of each of the two walls at opposing sides of the flue gas duct. The insert object comprises a part with a V- or wedge shaped cross section, with the bottom of the V- or wedge shape oriented in the average flue gas flow direction of the flue gas duct..
