Abstract
A plurality of baffles for adjacent finned tubes of a heat exchanger wherein a first fluid flows in the finned tubes and a second fluid of a different temperature flows past the finned tubes in heat transfer relationship therewith, include a baffle for each adjacent pair of finned tubes. A first flow path for second fluid extends in between baffles at one of the finned tubes, and a second flow path for second fluid extends in between baffles at an adjacent other of the finned tubes. The second flow path is larger between baffles at the other finned tube than the first flow path between baffles at the one finned tubes, and the second flow path is longer along baffles at the other finned tube than the first flow path along baffles at the one finned tube.
Claims20
A method of providing a plurality of baffles for adjacent finned tubes of a heat exchanger wherein a first fluid flows in said finned tubes and a second fluid of a different temperature flows past said finned tubes in heat transfer relationship therewith, comprising in combination the steps of:
- providing a baffle for each adjacent pair of finned tubes;
- providing a first flow path for second fluid in between baffles at one of said finned tubes;
- providing a second flow path for second fluid in between baffles at an adjacent other of said finned tubes;
- making said second flow path larger between baffles at said other finned tube than said first flow path between baffles at said one finned tube;
- and
- making said second flow path longer along baffles at said other finned tube than said first flow path along baffles at said one finned tube.
A method of providing a baffle for an adjacent pair of elongate finned tubes of a heat exchanger, wherein each of said tubes has an annular heat-exchange fin structure thereabout, comprising in combination the steps of:
- providing said baffle with two elongate sections at an obtuse angle for accommodating one of said heat-exchange fin structures;
- and
- providing said baffle with a third elongate section at an acute angle to one of said two elongate sections for accommodating the heat-exchange fin structures of both of said pair of elongate finned tubes at said acute angle.
A heat exchanger including a plurality of adjacent finned tubes, wherein a first fluid flows in said finned tubes and a second fluid of a different temperature flows past said finned tubes in heat transfer relationship therewith, comprising in combination:
- a baffle for each adjacent pair of finned tubes;
- a first flow path for second fluid in between baffles at one of said finned tubes;
- and
- a second flow path for second fluid in between baffles at an adjacent other of said finned tubes;
- said second flow path being larger between baffles at said other finned tube than said first flow path between baffles at said one finned tube;
- and
- said second flow path being longer along baffles at said other finned tube than said first flow path along baffles at said one finned tube.
A heat exchanger including a baffle for an adjacent pair of elongate finned tubes of the heat exchanger, wherein each of said tubes has an annular heat-exchange fin structure thereabout, comprising in combination:
- two elongate sections extending at an obtuse angle to each other so as to accommodate one of said heat-exchange fin structures;
- and
- a third elongate section extending at an acute angle to one of said two elongate sections so as to accommodate the heat-exchange fin structures of both of said pair of elongate finned tubes.
