Abstract
A monolithic, block-type heat exchange element having a series of fluid channels is manufactured by making use of extrusion molding. Extrudable molding material is extruded to form a continuous molding having opposed first and second surfaces. The extruded molding is provided with a series of discrete first passages and another series of discrete second passages both extending along the direction of extrusion and between the first and second surfaces. The molding is transversely cut into sections. At least parts of the molding section are then cut out along the first and second surfaces until the first passages are opened into the first and second surfaces. The openings of the first passages opened into the third and fourth surfaces extending perpendicular to the direction of extrusion are closed by suitable closure material to form a series of first fluid channels for a first heat exchange medium. The second passages extend throughout the molding section in the direction of extrusion and thus serve to form a series of second fluid channels for a second heat exchange medium.
