Heat exchanger plate and sealing gasket having a rotatable lock extending across the edge of the heat exchanger plates

摘要

A combination of a plurality of heat exchange plates 412, 416 and sealing gaskets 420 therefor, for use in a heat exchanger arrangement, each heat exchange plate having first and second sides, an edge, and a groove formed in the upper side thereof, extending along and spaced from the edge, and each sealing gasket having an elongate main portion 418, for seating in the groove of a first heat exchange plate, and for sealing between the first heat exchange plate and a second of the heat exchange plates when the second heat exchange plate is retained in compressive association therewith. A plurality of plate gripping portions 430 located in spaced arrangement along the length of the main portion, formed integrally therewith, and extending transversely away therefrom, for gripping predetermined portions of the plate so as to attach the gasket thereto, wherein the plate gripping portions are formed so as to provide to an assembler a visual indication as to whether the plate gripping portions and the plate are properly fastened together, at each predetermined portion of the plate
