Abstract (en)
Process for making a heat exchanger unit comprising a number of parallel tubes (4), enclosing channels for one of the heat exchanging fluidums and a heat conductive plate, the tubes being integrated in the plate (1). The process comprises the extrusion of a suitable metal, preferably aluminium, whereby the plate (1) and the tubes (4) are formed in one step. Preferably the plate (1) is extruded in a nearly circular fashion, and after extrusion, the plate (1) is reshaped into the required form. <IMAGE>
