Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
114 words
A method of mounting a heat exchanger core, having opposed inlet and outlet faces, between an inlet duct and an outlet duct, said method comprising the steps of: providing a first resilient gasket around the periphery of the inlet face of the heat exchanger core and a second resilient gasket around the periphery of the opposed outlet face of the heat exchanger core; disposing the heat exchanger core with the resilient gaskets between an inlet duct and an structurally joining the inlet duct to the outlet duct around the heat exchanger core to at least partially compress the resilient gaskets between the inlet and outlet ducts and the opposed inlet and outlet faces respectively.
Claim 2
Independent Claim
114 words
A method of mounting a heat exchanger core, having opposed inlet and outlet faces, between an inlet duct and an outlet duct, said method comprising the steps of: providing a first resilient gasket around the periphery of the inlet face of the heat exchanger core and a second resilient gasket around the periphery of the opposed outlet face of the heat exchanger core; disposing the heat exchanger core with the resilient gaskets between an inlet duct and an structurally joining the inlet duct to the outlet duct around the heat exchanger core to at least partially compress the resilient gaskets between the inlet and outlet ducts and the opposed inlet and outlet faces respectively.
Claim 3
Independent Claim
191 words
A method of mounting a plate fin heat exchanger core, having a high pressure inlet face and an opposed high pressure outlet face, between an inlet duct and an outlet duct, said method comprising the steps of: bonding a first resilient gasket around the periphery of the high pressure inlet face of the plate fin heat exchanger core; bonding a second resilient gasket around the periphery of the opposed high pressure outlet face of the plate fin heat exchanger core; providing an inlet duct to deliver high pressure fluid to the high pressure inlet face of the heat exchanger core; providing an outlet duct to receive high pressure fluid from the high pressure outlet face of the heat exchanger core; disposing the heat exchanger core between the inlet and outlet ducts; and structurally joining the inlet duct to the outlet duct around the heat exchanger core to at least partially compress the first resilient gasket between the inlet duct and the inlet face of the heat exchanger core and to at least partially compress the second resilient gasket between the outlet duct and the outlet face of the heat exchanger core.
Claim 4
Independent Claim
191 words
A method of mounting a plate fin heat exchanger core, having a high pressure inlet face and an opposed high pressure outlet face, between an inlet duct and an outlet duct, said method comprising the steps of: bonding a first resilient gasket around the periphery of the high pressure inlet face of the plate fin heat exchanger core; bonding a second resilient gasket around the periphery of the opposed high pressure outlet face of the plate fin heat exchanger core; providing an inlet duct to deliver high pressure fluid to the high pressure inlet face of the heat exchanger core; providing an outlet duct to receive high pressure fluid from the high pressure outlet face of the heat exchanger core; disposing the heat exchanger core between the inlet and outlet ducts; and structurally joining the inlet duct to the outlet duct around the heat exchanger core to at least partially compress the first resilient gasket between the inlet duct and the inlet face of the heat exchanger core and to at least partially compress the second resilient gasket between the outlet duct and the outlet face of the heat exchanger core.
Claim 5
Independent Claim
176 words
A method of mounting a plate fin heat exchanger core, having opposed high pressure inlet and outlet faces, between a high pressure inlet duct and a high pressure outlet duct, said method comprising the steps of: providing resilient gaskets around the periphery of the high pressure inlet face and the opposed high pressure outlet face of the heat exchanger core; disposing the heat exchanger core with the resilient gaskets between the high pressure inlet duct and the high pressure outlet duct, the high preSsure inlet face resilient gasket disposed between the high pressure inlet face and the high pressure inlet duct and the high pressure outlet face resilient gasket disposed between the high pressure outlet face and the high pressure outlet duct; and structurally joining the inlet duct directly to the outlet duct around the heat exchanger core to at least partially compress the resilient gaskets between the high pressure inlet and outlet ducts and the high pressure inlet and outlet faces respectively to structurally isolate the heat exchanger core from the inlet and outlet ducts.
Claim 6
Independent Claim
176 words
A method of mounting a plate fin heat exchanger core, having opposed high pressure inlet and outlet faces, between a high pressure inlet duct and a high pressure outlet duct, said method comprising the steps of: providing resilient gaskets around the periphery of the high pressure inlet face and the opposed high pressure outlet face of the heat exchanger core; disposing the heat exchanger core with the resilient gaskets between the high pressure inlet duct and the high pressure outlet duct, the high preSsure inlet face resilient gasket disposed between the high pressure inlet face and the high pressure inlet duct and the high pressure outlet face resilient gasket disposed between the high pressure outlet face and the high pressure outlet duct; and structurally joining the inlet duct directly to the outlet duct around the heat exchanger core to at least partially compress the resilient gaskets between the high pressure inlet and outlet ducts and the high pressure inlet and outlet faces respectively to structurally isolate the heat exchanger core from the inlet and outlet ducts.
Claim 7
Independent Claim
198 words
A method of mounting a heat exchanger core, having a high pressure inlet face and an opposed high pressure outlet face, between an inlet duct and an outlet duct, said method comprising the steps of: bonding a first resilient gasket around the periphery of the high pressure inlet face of the heat exchanger core; bonding a second resilient gasket around the periphery of the opposed high pressure outlet face of the heat exchanger core; providing an inlet duct to deliver high pressure fluid to the high pressure inlet face of the heat exchanger core; providing an outlet duct to receive high pressure fluid from the high pressure outlet face of the heat exchanger core; disposing the heat exchanger core between the inlet and outlet ducts; and structurally joining the inlet duct to the outlet duct around the heat exchanger core to at least partially compress the first resilient gasket between the inlet duct and the inlet face of the heat exchanger core and to at least partially compress the second resilient gasket between the outlet duct and the outlet face of the heat exchanger core, without structurally joining the heat exchanger core to the inlet and outlet ducts.
Claim 8
Independent Claim
198 words
A method of mounting a heat exchanger core, having a high pressure inlet face and an opposed high pressure outlet face, between an inlet duct and an outlet duct, said method comprising the steps of: bonding a first resilient gasket around the periphery of the high pressure inlet face of the heat exchanger core; bonding a second resilient gasket around the periphery of the opposed high pressure outlet face of the heat exchanger core; providing an inlet duct to deliver high pressure fluid to the high pressure inlet face of the heat exchanger core; providing an outlet duct to receive high pressure fluid from the high pressure outlet face of the heat exchanger core; disposing the heat exchanger core between the inlet and outlet ducts; and structurally joining the inlet duct to the outlet duct around the heat exchanger core to at least partially compress the first resilient gasket between the inlet duct and the inlet face of the heat exchanger core and to at least partially compress the second resilient gasket between the outlet duct and the outlet face of the heat exchanger core, without structurally joining the heat exchanger core to the inlet and outlet ducts.
