Patent ID: 8646517

Claim:
A heat exchanger plate for a plate heat exchanger, wherein the plate comprises: first and second ports positioned on opposite sides of a longitudinal centerline of the heat exchanger plate; a plurality of regions, including a distribution region, a heat transfer region, and adiabatic regions comprising a first adiabatic region and a second adiabatic region; an edge area that extends outside the ports and the regions; a first gasket groove extending in the edge area outside the regions and around the ports, wherein a first portion of the first gasket groove: (i) borders an entire edge of the first adiabatic region positioned farthest from the longitudinal centerline, and (ii) is nearer to the longitudinal centerline than an entirety of a second portion of the first gasket groove bordering the heat transfer region; and a second gasket groove positioned between the second adiabatic region and the distribution region, wherein the first gasket groove and the second gasket groove are connected together to accommodate a gasket for sealing abutment against an adjacent heat exchanger plate in the plate heat exchanger.
