Definitions

  • ABSTRACT Resilient elements are provided for the mounting of a heat exchanger core between structurally joined inlet and outlet ducts.
  • the present invention provides a heat exchanger particularly adaptable for use in generally adverse environments.
  • Theheat exchanger core is provided with a gasket or sealing element of a resilient or elastomeric material on both the inlet face and outlet face thereof.
  • This gasket may extend a short distance around the side of the heat exchanger core away from the inlet and outlet faces thereof respectively;
  • the heat exchanger core does not include any flanges or other structurally supporting mounting means.
  • the inlet duct and outlet duct on opposite sides of the heat exchanger are structurally connected to compress the gasket both on the inlet and outlet faces of the heat exchangercore and along the side edges of the inlet and outlet faces thereof.
  • FIG. 1 is a frontal elevation of the heat exchanger core of the present invention
  • FIG. 2 is a side elevation of the heat exchanger core of the present invention
  • FIGS. 1, 2 and 3 illustrate a conventional, cross flow, plate-fin heat exchanger including offset corrugated tins in the separate fluid passageways.
  • the frontal view shown. in FIG. 1 illustrates the inletface 11 of the high pressure side or hot fluid side of the heat exchanger core 10.
  • the hot fluid or high pressure passages 12 separated by header bars 14 to prevent hot fluid flow into the cold fluid passages are also shown.
  • the resilient material or elastomeric gasket 16 is shown extending around the entire periphery of the inlet face 11 of the heat exchanger core 10. As more clearly shown in FIGS. 2 and 3, the gasket 16 in- "cludes a side extension or wrap around portion 18 which extends around two opposed edges of the heat exchanger inlet face 11.
  • the side view of the heat exchanger core 10 illustrated in FIG. 2 shows the low pressure inlet face which includes cold fluid passageways 20 and side header bars 22.
  • the top view, FIG. 3, is partially cut away to show a cold fluid passage 20 and hot fluid passage 12,
  • the configuration of the gasket 16 is more clearly illustrated in FIGS. .4, 5 and 6.
  • the gasket includes a first flat face 30 which abuts the inlet face 11 of the heat exchanger core and a second flat face 32 disposed at a angle to the first flat face 30 to extend along the side face 19 of the heat exchanger core 10 adjacent to the inlet face 11.
  • the main portion of the gasket, which extends around the entire inlet face 11, includes an outwardprojection 34 having a substantially flat outer surface disposed at a slight angle from the plane of the inlet face 11.
  • the inlet duct associated with the heat exchanger core 10 will include a flange 40 having a flat face in substantially the same plane as the inlet face 11. of the heat exchanger core 10 so as to compress the gasket projection 34 towards the same plane as the inlet face 11.
  • the inletduct would also include a flange 42 to compress the side extending or wrap around portion 18 of the gasket 16 along the face 19 of the heat exchanger core 10. This flange 42 should be slightly flared to facilitate positioning of the core 10 and compression of the gasket.
  • the heat exchanger mounting of the present invention is particularly adapted for use in adverse environments such as on a vehicular engine.
  • the heat exchanger core 10 including a gasket 16 on both the hot fluid inlet and outlet faces thereof, is disposed between a compressed air duct 50 which receives compressed air from an engine turbocharger compressor 52, and the engine inlet manifold 54 which includes a manifold duct 56.
  • the compressed air duct 50 and inlet manifold duct 56 includes flanges 58 and 60 respectively to engage the gaskets 16 on the heat exchanger core 10.
  • a plurality of tie rods 62 together with structural sections of the inlet manifold duct 56, are used to join the compressed air duct 50 and inlet manifold duct 56 to secure the heat exchanger core 10 therebetween. Cooled air may be passed through the low pressure or cold side of the heat exchanger core 10 by a tip-turbine driven fan 64 which is driven by a portion of the compressed air from the turbocharger compressor 52 through bypass duct 66.
  • the gasket 16 may be of any resilient material such as a silicone elastomer (Silastic, a trademark of Dow Coming).
  • the gasket material must be selected to provide reasonable life when subjected to the operating environment in which the heat exchanger is to be used.
  • the gasket in most instances would be bonded to the inlet and outlet faces in the heat exchanger core by a Room Temperature vulcanizing (RTV) Silicone Elastomer.
  • RTV Room Temperature vulcanizing
  • the core can then be inserted directly into the cavity in the ducts carrying the fluid to be cooled and the assembly squeezed to a predetermined dimension by means of the tie bolts or other flange joining means.
  • the heat exchanger core does not require any integral flanges or machining operations prior to its use.
  • the ducts in which the heat exchanger core is to be inserted can be of cast material and likewise do not require any machining operations before use.
  • the side extending positions of the gaskets provide considerable resistance to vibration in all directions. This wrap around feature is exceedingly important in the vehicular applications. In order to insure that the resonant vibration frequency of the heat exchanger core is always higher than any driving frequency present, the squeeze or pressure on the gasket should be controlled.
  • Heat exchangers mounted in accordance with the present invention provide adequate sealing for the high pressure or hot fluid, while effectively preventing vibratory, thermal expansion or rigging stress from being transmitted to the fragile heat exchanger core.
  • the mounting costs are reduced since no machining operations are required.
  • the heat exchanger core can be easily replaced or removed for cleaning without damaging or replacing the more costly ducts.
