IMPROVED HEAT EXCHANGER HEADER STRUCTURE

摘要

A heat exchanger assembly comprising a stacked array of thin-walled heat exchange channel elements, having first fluid entrance and exit faces at opposite ends of the array. The improved headering arrangement includes a resilient gasket disposed around the perimeter of each face against the wall portion ends thereof and header tank means enclosing each face of the array, arranged to bear compressively against the resilient gasket and form a fluid-tight seal between the header tank and the stacked array.
