Patent ID: 8544529

Claim:
Heat exchanger comprising a set of plates defining circuits between the plates for a fluid flowing alternately via seals mounted between each pair of two adjacent plates, each plate including at least one guiding cut formed at least at one of ends of the plate for guiding each plate inside a frame, and further including, between each pair of two adjacent plates, and in proximity to the at least one guiding cut, at least one strut to be compressed and in contact with the two adjacent plates, each strut having, before compression, a thickness at least equal to a thickness of the seal, wherein an upper face of the at least one strut is first to come into contact with an upper plate of the two adjacent plates when the plates are positioned opposite one another in the frame, and wherein the at least one strut orients the two adjacent plates parallel to each other before the seal is acted upon by tightening of the plates.
