LM Radiator, Inc. - Hibbing MN
International Classification:
F28F 900
US Classification:
165 67, 165162, 122510

Removable Tube Heat Exchanger And Header Plate

View page
US Patent:
6964297, Nov 15, 2005
Filed:
Jul 14, 1999
Appl. No.:
09/357356
Inventors:
Robert Janezich - Hibbing MN, US

Assignee:
L & M Radiator, Inc. - Hibbing MN
International Classification:
F28F009/04
US Classification:
165178, 165 76, 165173, 285 19, 285231
Abstract:
A heat exchanger design is described which includes header plates, apertures, seals and flow tubes. A plurality of apertures in at least one header plate are configured to allow a flow tube to be inserted into or removed from the aperture as a whole at an angle. A seal is included within the aperture and is supported by differing diameters of the aperture wall. The seal engages the flow tube in a manner to allow high pressure operation of the heat exchanger when the flow tube is perpendicular to the header plate.

Removable Tube Heat Exchanger With Retaining Assembly

View page
US Patent:
8251134, Aug 28, 2012
Filed:
Nov 18, 2008
Appl. No.:
12/272880

International Classification:
F28F 9/02
F28F 9/04
US Classification:
165173, 165158
Abstract:
A header plate assembly for a heat exchanger includes a plate having a tube side and a tank side. A plurality of apertures extends through the plate. Each aperture has a first portion on the tube side of the plate, the first portion having a first cross-dimension, and a second portion adjacent the first portion and having a second cross-dimension that is smaller than the first cross-dimension, with a first shoulder being formed between the first and second portions. Each of a plurality of collars has an aperture extending therethrough, with a portion of each collar being received in the first portion of one of the apertures in the plate. A seal is positioned in each of the first portions of the apertures and between one of the collars and one of the first shoulders. A plurality of fasteners secures the collars to the plate.

US Patent:
20020036078, Mar 28, 2002
Filed:
Sep 28, 2001
Appl. No.:
09/965943
Inventors:
Robert Janezich - Hibbing MN, US
James Comstock - Goodland MN, US
International Classification:
F28D007/02
US Classification:
165/164000
Abstract:
A heat exchanger includes a heat exchanger shell having an inlet and outlet. A header plate including an inner member and an outer member defining a leak detection chamber therebetween is provided at each end of the heat exchanger shell. A plurality of heat exchanger tubes is positioned in the heat exchanger shell. Each tube extends through an aperture formed in an inner member and an aperture formed in an outer member of each of the header plates. A seal is provided in a channel in each aperture to sealingly engage a corresponding heat exchanger tube and a corresponding plate. A passage leads from the leak detection chamber to the exterior of the header plate.
