Method For Manufacturing A Disassembleable Core Heat Exchanger
View pageUS Patent:
46074236, Aug 26, 1986
Filed:
Nov 21, 1984
Appl. No.:
6/673680
Inventors:
Robert E. Sleep - Tampa FL
International Classification:
B21D 5302
B23P 600
B23P 600
US Classification:
291573R
Abstract:
A method of making the heat exchanger is also disclosed which includes a ring which is slipped over the periphery of the second tube retaining plate and brazed thereto and a gasket which is slipped over the tube core to form a seal between the first end portion and the elongated housing. An O-ring is slipped over the ring after the replacement of the core tubes within the housing. The O-ring seal forms a seal between the ring and the housing when the two end portions are moved towards each other by adjustable tie rods. An alternative embodiment of the invention includes an annular ledge defined by a ring or seal seat encircling the tube retaining plate and an annular shoulder extending between a bore and a counterbore of the elongated housing. The ledge and the shoulder are coplanar such that an O-ring pressed against a washer seated against the ledge and shoulder seals the annular groove between the tube retaining plate and the housing. A method for converting a flangeless-type heat exchanger into a disassembleable core heat exchanger is disclosed, also.
Disassembleable Core Heat Exchanger
View pageUS Patent:
47734752, Sep 27, 1988
Filed:
Mar 24, 1987
Appl. No.:
7/030251
Inventors:
Robert E. Sleep - Tampa FL
International Classification:
F28F 700
US Classification:
165 76
Abstract:
A disassembleable core heat exchanger is disclosed. The heat exchanger includes an elongated housing which defines a first passageway. A first end portion defines a second passageway which registers with the "passageway". A first tube retaining plate is metallurgically sealed within the first opening and a plurality of core tubes extend through and are sealingly engaged to the first tube retaining plate. The core tubes slidably extend through the passageway to a second tube retaining plate which is disposed remote from the first tube retaining plate. A first seal is disposed between the first end portion and the elongated housing. A second seal is disposed between a second end portion and the passageway. The second end portion cooperates with the second tube retaining plate. The two end portions are adjustably clamped relative each other to seal the second tube retaining plate relative to the elongated housing.
Indicator Device For A Heat Exchanger
View pageUS Patent:
46826475, Jul 28, 1987
Filed:
Feb 7, 1986
Appl. No.:
6/827258
Inventors:
Robert Sleep - Tampa FL
International Classification:
F28F 700
US Classification:
165 111
Abstract:
An indicator device is disclosed for indicating that a heat exchanger has been disassembled, cleaned, inspected, reconditioned and subsequently reassembled and rebrazed. The device includes an elongate housing which defines an inlet and an outlet port. A first and a second tube plate are spaced axially within the housing and a plurality of heat exchange tubes extend through and between the plates. A first seal is disposed between the plates and the tubes for sealing the tubes relative to the plates and a second seal is disposed between the tube plates and the housing for sealing the tube plates within the housing. An elongate flexible metallic strip having a first and a second end is threaded through one port and around at least one of the tubes and back through the same or opposite port and an indicator seal extends around the first and second ends of the flexible strip for sealingly connecting together the ends of the flexible strip for indicating that the heat exchanger has been disassembled, cleaned, inspected, reconditioned and subsequently reassembled and rebrazed.
