Heat exchanger plate and such a plate with a gasket
View Patent ↗A heat exchanger plate includes a gasket groove that extends through a portion of the plate proximate to the periphery of the plate. The groove includes spaced expanded portions disposed to receive a plurality of coupling elements formed on an associated gasket. The expanded portions include tongue-like ridged portions with openings substantially perpendicular to the longitudinal direction of the gasket groove that are configured to receive the gasket coupling elements.
1. A heat exchanger plate for use in combination with a gasket in a plate-type heat exchanger, said plate comprising a gasket groove formed by an indentation that extends through at least portion of the heat exchanger plate spaced from the periphery of the plate, a plurality of expanded groove portions disposed in substantially the same plane as said gasket groove at spaced intervals, a first ridged, tongue-like portion disposed in each of the expanded groove portions extending upwardly from the gasket groove, said first tongue-like portion formed by cutting and ridging of the heat exchanger plate to expose first and second openings on the respective sides of said first tongue-like portion substantially perpendicular to the longitudinal direction of the gasket groove, said gasket including a plurality of coupling elements, each of said coupling elements configured to be received in a respective one of said expanded groove portions and engaged by said first tongue-like portion.
2. A heat exchanger plate according to claim 1 , further comprising a second ridged, tongue-like portions disposed at a distance from said first tongue-like portion in each of the expanded groove portions.
3. A heat exchanger plate according to claim 1 , wherein said first tongue-like portion is provided centrally in each of the expanded portions; and wherein each of the coupling elements of the gasket comprises two protruding flaps configured for engagement within the first and second openings.
4. A heat exchanger plate according to claim 3 , wherein the flaps on each of the coupling elements of the gasket extend partially into the first and second openings.
5. A heat exchanger plate according to claim 3 , wherein the flaps on each of the coupling elements of the gasket extend marginally into the first and second openings.
6. A heat exchanger plate according to claim 3 , wherein each of the coupling elements of the gasket is provided with a superjacent pressure element.
7. A heat exchanger plate according to claim 1 , further comprising a second ridged, tongue-like portions spaced from said first tongue-like portion in each of the expanded groove portions, said second ridged tongue-like portion formed by cutting and ridging of the heat exchanger plate to expose third and fourth openings on the respective sides of said second tongue-like portion, said first opening and said third opening defining proximal, mutually facing openings; and wherein each of the coupling elements of the gasket comprises a protruding flap configured for engagement within the proximal, mutually facing openings.
8. A heat exchanger plate according to claim 7 , wherein the flaps on the each of coupling elements of the gasket extend partially into the proximal, mutually facing openings.
9. A heat exchanger plate according to claim 7 , wherein the flaps on each of the coupling elements of the gasket extend marginally into the proximal, mutually facing openings.
10. A heat exchanger plate according to claim 7 , wherein the coupling element of the gasket is provided with a superjacent pressure element.
11. A heat exchanger plate according to claim 1 , further comprising a second ridged, tongue-like portions spaced from said first tongue-like portion in each of the expanded groove portions, said second ridged tongue-like portion formed by cutting and ridging of the heat exchanger plate to expose third and fourth openings on the respective sides of said second tongue-like portion, said second openings and said fourth opening defining opposed, distal openings; and wherein each of the coupling elements of the gasket comprises two outwardly protruding flaps that are configured for engagement within the opposed distal openings.
12. A heat exchanger plate according to claim 11 , wherein the flaps on each of the coupling elements of the gasket extend partially into the opposed distal openings.
13. A heat exchanger plate according to claim 11 , wherein the flaps on each of the coupling elements of the gasket extend marginally into the opposed distal openings.
14. A heat exchanger plate according to claim 11 , wherein each of the coupling elements of the gasket is provided with a superjacent pressure element.
15. A heat exchanger plate according to claim 1 , wherein each of the coupling elements of the gasket is provided with a superjacent pressure element.
16. A heat exchanger plate for use in combination with a gasket in a plate-type heat exchanger, said plate comprising a gasket groove formed by an indentation that extends through at least portion of the heat exchanger plate spaced from the periphery of the plate, a plurality of expanded groove portions disposed in substantially the same plane as said gasket groove at spaced intervals, a first ridged, tongue-like portion disposed in each of the expanded groove portions extending upwardly from the gasket groove, said first tongue-like portion formed by cutting and ridging of the heat exchanger plate to expose first and second openings on the respective sides of said first tongue-like portion substantially perpendicular to the longitudinal direction of the gasket groove, said gasket including a plurality of coupling elements, each of said coupling elements configured to be received in a respective one of said expanded groove portions and including protruding flaps that are engaged within said first and second openings by said first tongue-like portion.
17. A heat exchanger plate according to claim 16 , wherein the flaps on the coupling element of the gasket extend partially into the first and second openings.
18. A heat exchanger plate according to claim 17 , wherein each of the coupling elements of the gasket is provided with a superjacent pressure element.
19. A heat exchanger plate according to claim 16 , wherein the flaps on each of the coupling elements of the gasket extend marginally into the first and second openings.
20. A heat exchanger plate according to claim 19 , wherein each of the coupling elements of the gasket is provided with a superjacent pressure element.
