A heat exchanger device and method of making same disclosed has a heat exchanger core and a stack of inner plates with alternating hot and cold flow fluid passages producing diagonal flow therethrough. One embodiment adds a pair of core retaining plates with end portions extending beyond the core with apertures at precise locations to connect with connectors of equipment to which it is coupled and the other embodiment has end connectors that weld to the core to provide straight in line fluid flow.

[ What is claimed is:] [1.] A heat exchanger device comprising:a separately constructed, leak tested heat exchanger core having flat opposed first and second outer core plates, a stack of parallel spaced inner core plates between said first and second outer core plates, said outer core plates being constructed of a thickness or material having a greater ability to resist pressure than said inner core plates with spaces between said inner core plates defining alternate flow passages for hot and cold fluids, said outer core plates extending parallel to said inner core plates,an attachable first core retaining plate affixed to one face of said core and extending parallel to said first outer core plate having opposed first and second end portions extending beyond the ends of said core and having a first pair of flow apertures at preselected precise positions in relation to flow line connectors to which the device is connected,an attachable second core retaining plate affixed to an opposite face of said core and extending parallel to said second outer core plate having opposed first and second end portions extending beyond the ends of said core with a second pair of apertures at preselected precise positions in relation to flow line connectors to which the device is connected for fluid flow,attachable first end wall portions connected to said first and second core retaining plates at one end of said core forming first flow compartments to pass fluid toward and away from said core and through one each of said first and second pairs of apertures, andattachable second end wall portions connected to said top and bottom core retaining plates at an opposite end of said core forming second flow compartments to pass fluid toward and away from said core and through one each of said other of said first and second pairs of apertures.
