摘要:
A heat exchanger includes a plurality of tubes, a collection tank having an inlet port and an internal chamber in fluid communication with the plurality of tubes, a header coupled to the collection tank and having a plurality of apertures each dimensioned to receive a corresponding tube, a gasket separating the header from the collection tank and sealing a gap between the header and the collection tank, and a reinforcement retaining the gasket in position between the header and the collection tank. The reinforcement includes a first web extending across the internal chamber and a second web spaced apart from the first web and extending across the internal chamber. The heat exchanger also includes a baffle coupled to and extending between the first web and the second web. The baffle extends across at least a portion of the internal chamber between the inlet port and the plurality of tubes.

摘要:
A heat exchanger having a collection tank having an internal chamber and a header connected to the collection tank and receiving a number of flat tubes through apertures in the header. A reinforcing member received within the collection tank and/or the header functions to reinforce the header and/or the collection tank in applications where these elements are subject to internal pressures that would otherwise deform the header and/or collection tank to an unacceptable extent. The heat exchanger may include a curved gasket on each flat tube to match the shape of the flat tubes and a curved header. Also, another gasket can be located between a metal or plastic collection tank and a plastic or metal header, respectively, to prevent leakage therebetween.
摘要:
Various embodiments of the present invention provide a heat exchanger having a collection tank having an internal chamber, and a header connected to the collection tank and receiving a number of flat tubes through apertures in the header. In some embodiments, a reinforcing member received within the collection tank and/or the header functions to reinforce the header and/or the collection tank in applications where these elements are subject to internal pressures that would otherwise deform the header and/or collection tank to an unacceptable extent. Also, some heat exchanger embodiments utilized a curved gasket on each flat tube to match the shape of the flat tubes and a curved header. Also, another gasket can be located between a metal or plastic collection tank and a plastic or metal header, respectively, to prevent leakage therebetween.
摘要:
A housing for transporting a generally cylindrical canister configured to store at least one of a pressurized gas and a pressurized liquid. The housing includes a first housing section and a second housing section that is movable with respect to the first housing section from a first operating condition to a second operating condition. A heat transfer element is coupled to at least one of the first and the second housing sections to define at least a portion of a boundary of a generally cylindrical volume. The canister is generally fixed from movement with respect to the first and the second housing sections when the second housing section is in the first operating condition, and the canister is movable with respect to the first and the second housing sections and configured to be removed from the generally cylindrical volume when the second housing section is in the second operating condition.

摘要:
A reduction in tube to header joint failures in a heat exchanger having spaced headers (12,14), elongated, side-by-side parallel spaced tube slots (22) in the headers (12,14) along the length thereof and a plurality of flattened tubes (26) having ends (24) received in the tube slots (22) and metallurgically bonded to the header (12,14) thereat was achieved through the use of a reinforcing structure (38) having at least two projections (40) having a cross sectional shape complimentary to at least a part of the surface of the tubes (26) at their ends (24) and a length sufficient to extend along the tube ends (24) to a location past the metallurgical bonds between the tube ends (24) and a header (12,14), and a spine (44) extending transverse to the projection. Also disclosed is a reinforcing structure (38) and a method of reinforcing the tube to header joints in a heat exchanger.
摘要:
A header plate for a heat exchanger includes a first side flange, a second side flange spaced apart from and opposing the first flange, and a generally planar surface located between and connecting the first and second flanges. The generally planar surface and the first and second side flanges together at least partially define an internal volume of the heat exchanger. The header plate also includes a bead formed into the generally planar surface to locally deform the surface in a direction away from the internal volume, the bead extending to and blending into the first side flange. The header plate also includes a tube receiving opening extending through the generally planar surface into the internal volume, the tube receiving opening extending through the bead.

摘要:
A tube for use in a heat exchanger tube assembly is made by forming a round tube, reducing the diameter of an end section of the round tube, and flattening another section of the round tube. A transition zone is partially created by reducing of the diameter, and is further created by flattening the tube.
