PROCESS FOR MANUFACTURE OF A HEAT EXCHANGER CORE

摘要

The present invention relates to a process for manufacture of a core (1) of a heat exchanger (10) that comprises the steps of arranging a plurality of spacers (2, 20, 200) between planar plates (3, 30, 300); stacking, in an ordered manner, a set of planar plates (3, 30, 300) with spacers (2, 20, 200) between the planar plates in such a manner as to form an exchanger block; and applying a welding process to the formed block. In an alternative embodiment of the present invention, the process dispenses with the use of the planar plates (3, 30, 300), using the surface of the hollow spacers (2) as separation surface.
