Internally mounted radial flow, high pressure, intercooler for a rotary compressor machine

摘要

A header construction intended for use in a heat exchanger ( 36 ) employed in a relatively high pressure application includes an array of generally parallel tube runs ( 84 ) with fins ( 82 ) extending between adjacent ones of the tube runs. At least one relatively flat header plate ( 86 ) has a plurality of tube slots ( 88 ) for receiving ends ( 90 ) of the tubes ( 84 ) and a tank ( 94 ) is mounted to and sealed to the header plate ( 86 ). Peripheral flanges ( 112 ) are located about tube slots ( 86 ) in the headers and a header reinforcing plate ( 114 ) is bonded to the header plate ( 86 ) oppositely of the tank ( 94 ). Stiffening beads in the form of flanges ( 120 ) are located on the header reinforcing plate ( 114 ) between openings ( 118 ) therein through which the tubes ( 84 ) pass and extend away from the header plate ( 86 ).
