Abstract
There is provided a gas heat exchanger 101 comprising a coolant conduit 102 having a coolant inlet 103 and a coolant outlet 104, a gas cooling conduit 201, and a gas bypass conduit 203. At least a portion of the gas cooling conduit 201 is disposed between at least a portion of the coolant conduit 102 and a portion of the bypass conduit 203. During a first mode of operation, the gas cooling conduit 201 is configured to carry gas. During a second mode of operation, the bypass conduit 203 is configured to carry gas and the gas cooling conduit 201 is configured to reduce a heat exchange between the coolant conduit 102 and the bypass conduit 203.
Claims25
A method of manufacturing a gas heat exchanger comprising the steps of:
- providing a coolant conduit;
- providing a gas cooling conduit;
- providing a gas by-pass conduit;
- disposing at least a portion of said gas cooling conduit between at least a portion of said coolant conduit and at least a portion of said gas bypass conduit such that said gas cooling conduit is configured to provide a thermal barrier between said coolant conduit and said gas by-pass conduit;
- and further comprising the steps of
- disposing said gas by-pass conduit substantially within said gas cooling conduit, such that said gas by-pass conduit and said gas cooling conduit are substantially concentric;
- disposing at least one first spacer between said gas by-pass conduit and said gas cooling conduit such that said first spacer maintains said gas by-pass conduit and said gas cooling conduit in a substantially concentric position;
- disposing said gas cooling conduit substantially within said coolant conduit, such that said gas cooling conduit and said coolant conduit are substantially concentric;
- disposing at least one second spacer between said gas cooling conduit and said coolant conduit such that said second spacer maintains said gas cooling conduit and said coolant conduit in a substantially concentric position;
- and
- affixing said coolant conduit, said gas cooling conduit and said gas bypass conduit together at at least one end.
A method of manufacturing a gas heat exchanger comprising the steps of:
- providing a coolant conduit;
- providing a gas cooling conduit;
- providing a gas by-pass conduit;
- disposing at least a portion of said gas cooling conduit between at least a portion of said coolant conduit and at least a portion of said gas bypass conduit such that said gas cooling conduit is configured to provide a thermal barrier between said coolant conduit and said gas by-pass conduit;
- and further comprising the steps of
- forming a first spacer between said gas by-pass conduit and said gas cooling conduit by pressing a depression in a surface of said gas cooling conduit;
- and
- forming a second spacer between said gas cooling conduit and said coolant conduit by pressing a depression in a surface of said coolant conduit.
A method of manufacturing a gas heat exchanger comprising:
- providing a coolant conduit;
- providing a gas cooling conduit;
- providing a gas by-pass conduit;
- disposing at least a portion of said gas cooling conduit between at least a portion of said coolant conduit and at least a portion of said gas bypass conduit such that said gas cooling conduit is configured to provide a thermal barrier between said coolant conduit and said gas by-pass conduit.
A gas heat exchanger comprising:
- a coolant conduit;
- a gas cooling conduit;
- and
- a gas by-pass conduit;
- wherein at least a portion of said gas cooling conduit is disposed between at least a portion of said coolant conduit and at least a portion of said gas by-pass conduit, wherein said gas cooling conduit is configured to provide a thermal barrier between said coolant conduit and said gas by-pass conduit;
- wherein said coolant conduit comprises an outer tube;
- and
- said gas cooling conduit comprises a first inner tube, said first inner tube being disposed substantially within said outer tube;
- and
- said gas by-pass conduit comprises a second inner tube, said second inner tube being substantially disposed within said first inner tube.
A gas heat exchanger comprising:
- a coolant conduit;
- a gas cooling conduit;
- a gas by-pass conduit;
- wherein at least a portion of said gas cooling conduit is disposed between at least a portion of said coolant conduit and at least a portion of said gas by-pass conduit, wherein said gas cooling conduit is configured to provide a thermal barrier between said coolant conduit and said gas by-pass conduit.
