Heat exchange assembly

A heat exchange assembly comprising:

• a plurality of plates disposed in a spaced-apart arrangement, each of said plurality of plates includes a plurality of passages extending internally from a first end to a second end for directing flow of a heat transfer fluid in a first plane;
• a plurality of first end-piece members equaling the number of plates and a plurality of second end-piece members also equaling the number of plates, each of said first and second end-piece members including a recessed region adapted to fluidly connect and couple with the first and second ends of said plate, respectively, and further adapted to be affixed to respective adjacent first and second end-piece members in a stacked formation, wherein the depth of the recessed region is greater than the thickness of the plate, and the opposed surface from the recessed region of the corresponding first and second end-piece members includes a raised portion adapted for fitting into the recessed region of an adjacent end-piece member in conjunction with the end portion of the adjacent plate, and each of said first and second end-piece members further including at least one cavity for enabling entry of said heat transfer fluid into the plate, exit of said heat transfer fluid from said plate, or 180° turning of said fluid within the plate to create a fluid flow path between points of entry and exit of said fluid;
• and
• at least two fluid conduits extending through the stacked plurality of first and second end-piece members for providing first fluid connections between the parallel fluid entry points of adjacent plates and a fluid supply inlet, and second fluid connections between the parallel fluid exit points of adjacent plates and a fluid discharge outlet so that the heat transfer fluid travels in parallel paths through each respective plate.
