High pressure port peninsula

Abstract

A brazed plate heal exchanger ( 400 ) for exchanging heat between at least two media, wherein at least one of the media could have a working pressure of at least 50 bars, comprises a number of heat exchanger plates ( 100; 200 ) comprising a pressed pattern of ridges and grooves. Those are adapted to form flow channels for media to exchange heat flowing through said flow channels. The plates ( 100; 200 ) further comprises port openings ( 120, 130; 220; 300, 310 ) arranged to allow fluid communication with said flow channels and a skirt ( 140 ) extending around the periphery of the heat exchanger plates ( 100; 200 ). Skirts ( 140 ) of neighboring plates ( 100; 200 ) are arranged to contact one another in an overlapping manner in order to obtain a connection sealing the flow channels. At least one of said port openings ( 120, 130; 220; 300, 310 ) is placed on a peninsula ( 150 ) surrounded by the skirt ( 140 ) over at least 100 degrees.

1 . A brazed plate heat exchanger for exchanging heat between at least two media, wherein at least one of the media could have a working pressure of at least 50 bars, the heat exchanger comprising a number of heat exchanger plates comprising a pressed pattern of ridges and grooves adapted to form flow channels for media to exchange heat flowing through said flow channels, the plates further comprising port openings arranged to allow fluid communication with said flow channels and a skirt extending around the periphery of the heat exchanger plates, skirts of neighboring plates being arranged to contact one another in an overlapping manner in order to obtain a connection sealing the flow channels, wherein at least one of said port openings is placed on a peninsula surrounded by the skirt over at least 100 degrees. 
     
     
         2 . The brazed plate heat exchanger of  claim 1 , wherein the skirt surrounds the at least one port opening provided on the peninsula over at least 120 degrees.
