Heat transfer plate for a plate-and-shell heat exchanger

Abstract

A heat transfer plate configured to be arranged in a plate-and-shell type plate heat exchanger. The heat transfer plate comprises an inlet port and an outlet port. The inlet port has a first inlet section that faces the outlet port and comprises a first fluid blocker, for distribution of at least a part of a flow of fluid over a second inlet section of the inlet port. The outlet port has a first outlet section that faces the inlet port and comprises a second fluid blocker, for distribution of at least a part of the flow of fluid over a second outlet section of the outlet port. Corrugations are arranged intermediate the inlet port and the outlet port.

1 . A heat transfer plate configured to be arranged in a plate-and-shell heat exchanger, the heat transfer plate comprising an inlet port and an outlet port arranged at a distance from the inlet port,
 the inlet port having a first inlet section that faces the outlet port and comprises a first fluid blocker, for distribution of at least a part of a flow of fluid over a second inlet section of the inlet port,   the outlet port having a first outlet section that faces the inlet port and comprises a second fluid blocker, for distribution of at least a part of the flow of fluid over a second outlet section of the outlet port, wherein   a first abutment section is arranged around a periphery of a first side of the heat transfer plate,   a second abutment section is arranged around the inlet port and a third abutment section is arranged around the outlet port, at a second side of the heat transfer plate that is opposite the first side,   the first abutment section is configured to be joined by welding with a corresponding abutment section of a first, similar heat transfer plate that is arranged at the first side, and   the second and third abutment sections are configured to be joined by welding with corresponding abutment sections of a second, similar heat transfer plate at the second side, wherein   the heat transfer plate comprises corrugations arranged intermediate the inlet port and the outlet port, and wherein   the heat transfer plate is configured to distribute the flow of fluid at a pressure of at least 80 bars.   
     
     
         2 . A heat transfer plate according to  claim 1 , wherein the corrugations comprise elongated ridges and grooves that are parallel to a first axis that is inclined by an angle (α) of 15-75° in relation to a second axis that extends through a centre of the inlet port and through a centre of the outlet port. 
     
     
         3 . A heat transfer plate according to  claim 2 , wherein all ridges and grooves of the corrugations are parallel to the first axis. 
     
     
         4 . A heat transfer plate according to  claim 1 , wherein the corrugations surround the inlet port and the outlet port. 
     
     
         5 . A heat transfer plate according to  claim 1 , wherein the first and the second fluid blockers are arranged on the first side of the heat transfer plate. 
     
     
         6 . A heat transfer plate according to  claim 1 , wherein the heat transfer plate, the inlet port and the outlet port have circular shapes, and the fluid blockers have the shape of circular arcs. 
     
     
         7 . A heat transfer plate according to  claim 1 , wherein at least one of the fluid blockers comprises openings such that an amount of fluid may flow through the fluid blocker. 
     
     
         8 . A heat transfer plate according to  claim 1 , wherein the fluid blockers are pressed into the heat transfer plate, such they form a respective fluid-blocking ridge. 
     
     
         9 . A heat transfer plate according to  claim 1 , wherein the inlet port is positioned at least 4 cm from a peripheral edge of the heat transfer plate. 
     
     
         10 . A stack of heat transfer plates comprising a number of heat transfer plates according to  claim 1 . 
     
     
         11 . A plate-and-shell heat exchanger comprising a number of heat transfer plates according to  claim 1 .
