Abstract

A heat transfer plate ( 10 ) for a plate heat exchanger ( 100 ) includes: a plate body ( 11 ) which has a gasket groove ( 12 ) with a groove wall ( 13, 14 ), the groove wall ( 13, 14 ) having a groove wall body ( 130, 140 ); and a ridge ( 20 ) disposed on the groove wall body ( 130, 140 ) of a segment ( 120 ) of the gasket groove ( 12 ) in a length direction of the gasket groove ( 12 ).

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A heat transfer plate for a plate heat exchanger, the heat transfer plate comprising:
 a plate body which has a gasket groove with a groove wall, the groove wall having a groove wall body; and   a ridge disposed on the groove wall body of a segment of the gasket groove in a length direction of the gasket groove.   
     
     
         2 . The heat transfer plate of  claim 1 , wherein:
 the groove wall comprises two side walls and a bottom wall, each of the two side walls having a side wall body, the bottom wall having a bottom wall body, and the groove wall body comprising the side wall bodes and the bottom wall body; and   the ridge is disposed on at least one of the bottom wall body and the side wall bodies of the segment of the gasket groove in the length direction of the gasket groove.   
     
     
         3 . The heat transfer plate of  claim 1 , wherein:
 the ridge is projected from the groove wall body in a direction from an outside of the gasket groove toward an inside of the gasket groove.   
     
     
         4 . The heat transfer plate of  claim 1 , wherein:
 the ridge is projected from the groove wall body in a direction from an inside of the gasket groove toward an outside of the gasket groove.   
     
     
         5 . The heat transfer plate of  claim 2 , wherein:
 the ridge is projected from the at least one of the bottom wall body and the side wall bodies in a direction from an outside of the gasket groove toward an inside of the gasket groove.   
     
     
         6 . The heat transfer plate of  claim 2 , wherein:
 the ridge is projected from the at least one of the bottom wall body and the side wall bodies in a direction from an inside of the gasket groove toward an outside of the gasket groove.   
     
     
         7 . The heat transfer plate of  claim 2 , further comprising:
 a heat exchanging area surrounded by the gasket groove,   wherein the ridge is disposed on one of the side wall bodies facing towards the heat exchanging area.   
     
     
         8 . The heat transfer plate of  claim 2 , further comprising:
 a heat exchanging area surrounded by the gasket groove,   wherein the ridge is disposed on one of the side wall bodies facing away from the heat exchanging area.   
     
     
         9 . The heat transfer plate of  claim 2 , wherein:
 the ridge is disposed on at least one of the side wall bodies, and is closer to the bottom wall body than to the plate body.   
     
     
         10 . The heat transfer plate of  claim 2 , wherein:
 the ridge is disposed on a middle portion of the bottom wall body in a width direction of the bottom wall body.   
     
     
         11 . The heat transfer plate of  claim 2 , further comprising:
 a heat exchanging area surrounded by the gasket groove,   wherein the ridge is disposed on a side of the bottom wall body facing towards the heat exchanging area in a width direction of the bottom wall body.   
     
     
         12 . The heat transfer plate of  claim 2 , further comprising:
 a heat exchanging area surrounded by the gasket groove,   wherein the ridge is disposed on a side of the bottom wall body facing away from the heat exchanging area in a width direction of the bottom wall body.   
     
     
         13 . The heat transfer plate of  claim 1 , wherein:
 the segment of the gasket groove extends essentially parallel to an edge of the plate body.   
     
     
         14 . The heat transfer plate of  claim 1 , wherein:
 the segment of the gasket groove extends essentially parallel to a length direction of the plate body.   
     
     
         15 . A plate heat exchanger, comprising:
 a plurality of heat transfer plates of  claim 1 , which are stacked on top of each other; and   gaskets disposed in the gasket grooves of some of the plurality of heat transfer plates.   
     
     
         16 . The heat transfer plate of  claim 5 , further comprising:
 a heat exchanging area surrounded by the gasket groove,   wherein the ridge is disposed on one of the side wall bodies facing towards the heat exchanging area.   
     
     
         17 . The heat transfer plate of  claim 6 , further comprising:
 a heat exchanging area surrounded by the gasket groove,   wherein the ridge is disposed on one of the side wall bodies facing towards the heat exchanging area.   
     
     
         18 . The heat transfer plate of  claim 5 , further comprising:
 a heat exchanging area surrounded by the gasket groove,   wherein the ridge is disposed on one of the side wall bodies facing away from the heat exchanging area.   
     
     
         19 . The heat transfer plate of  claim 6 , further comprising:
 a heat exchanging area surrounded by the gasket groove,   wherein the ridge is disposed on one of the side wall bodies facing away from the heat exchanging area.   
     
     
         20 . The heat transfer plate of  claim 5 , wherein:
 the ridge is disposed on at least one of the side wall bodies, and is closer to the bottom wall body than to the plate body.
