Abstract

An elongate heat exchanger for cooling hot gas includes an arrangement for reducing thermal stresses when mounted in a housing. A pair of planar extensions project from opposite sides of the core. A mounting bracket has a central portion adapted to extend across the top of the core, and a pair of edge portions projecting outwardly from the central portion. The edge portions are substantially parallel to the planar extensions, and each has a top layer at least partially covering one of the planar extensions, wherein each of the edge portions is adapted to be secured to the housing, for example by a bolt. Each planar extension may be slidably received in a slot between the top and bottom layers of the edge portion, or may be slidably received between the top layer and the housing, to permit longitudinal thermal expansion of the core.

First claim

What is claimed is:

1. A heat exchanger comprising:
(a) a core having a top, a bottom, a pair of sides, a first end and a second end, an inlet and an outlet for a first fluid, and an inlet and an outlet for a second fluid, the sides extending parallel to a longitudinal axis;
(b) a first mounting arrangement for securing the first end of the core to a first surface;
(c) a second mounting arrangement for securing the second end of the core to a second surface, wherein the second mounting arrangement comprises a pair of planar extensions located proximate to the second end of the core, each of the planar extensions being rigidly secured to one of the sides of the core and extending outwardly from the side to which it is secured;
(d) a mounting bracket for securing the second end of the core to the second surface, wherein the mounting bracket has a central portion and a pair of edge portions attached to the central portion and projecting therefrom,
wherein the central portion is adapted to cover a portion of the top of the core proximate to the second end thereof, and has a width sufficient to extend across the top of the core,
wherein, with the central portion covering said portion of the top of the core, the edge portions project outwardly from opposite sides of the central portion and from opposite sides of the core, with each of the edge portions being substantially parallel to one of the planar extensions, and
wherein each of the edge portions has a top layer with a width sufficient to at least partially cover one of the planar extensions with the central portion covering said portion of the top of the core, and wherein each of the edge portions is adapted to be secured to the second surface;
wherein each of the edge portions of the mounting bracket has an aperture through which it is adapted to be secured to the second surface with a mechanical fastener;
wherein the top layer of each of the edge portions includes an area which lies outside an edge of one of the planar extensions with the central portion of the mounting bracket covering said portion of the top of the core; and
wherein each of the apertures in the edge portions is located in one of said outer areas, such that the edge portions are adapted to be secured directly to the second surface without passing through the planar extensions.

2. The heat exchanger of claim 1 , wherein the first mounting arrangement comprises a pair of planar extensions located proximate to the first end of the core, each of which is rigidly secured to one of the sides of the core and extends outwardly from the side to which it is secured; and
wherein each of the planar extensions located proximate to the first end of the core is adapted to be secured to the first surface.

3. The heat exchanger of claim 2 , wherein the first and second mounting arrangements are both provided by a pair of mounting flanges, each of the mounting flanges extending axially along one of the sides of the core between the first and second ends, and each of the mounting flanges being rigidly secured to one of the sides and extending outwardly from the side to which it is secured, wherein the first mounting arrangement comprises portions of the mounting flanges located proximate to the first end of the core and the second mounting arrangement comprises portions of the mounting flanges located proximate to the second end of the core.

4. The heat exchanger of claim 1 , wherein the top layer of the edge portions are wider than the planar extensions, such that the outer areas are located outwardly of side edges of the planar extensions with the central portion of the mounting bracket covering said portion of the top of the core.

5. The heat exchanger of claim 4 , wherein each of the edge portions of the mounting bracket further includes a bottom layer, wherein the top and bottom layers are planar and are separated by a space sufficient to receive one of the planar extensions in axial sliding relation;
wherein the top and bottom layers are joined along an axially extending line located outwardly of the side edge of the planar extension with the mounting bracket in the installed position, such that the space between the top and bottom layers of each of the mounting brackets defines an axially-extending slot which is open along its inner edge and closed along its outer edge.

6. The heat exchanger of claim 5 , wherein the axially extending line is located inwardly of the aperture in each of the edge portions.

7. The heat exchanger of claim 1 , wherein the mounting bracket protrudes beyond the second end of the core, and the outer areas of the edge portions are axially spaced from end edges of the planar extensions with the central portion of the mounting bracket covering said portion of the top of the core.

8. The heat exchanger of claim 7 , wherein each of the edge portions of the mounting bracket further includes a bottom layer, wherein the top and bottom layers are planar and are separated by a space sufficient to receive one of the planar extensions in axial sliding relation;
wherein the top and bottom layers are joined along a transversely extending line located outwardly of the end edge of the planar extension with the mounting bracket in the installed position.

9. The heat exchanger of claim 8 , wherein the top and bottom layers are also joined along an axially extending line located outwardly of the side edge of the planar extension with the central portion of the mounting bracket covering said portion of the top of the core, such that the space between the top and bottom layers of each of the mounting brackets defines an axially-extending slot which is open along its inner edge and closed along its outer edge and along a transverse edge defined by said transversely extending line.

10. A heat exchanger comprising:
(a) a core having a top, a bottom, a pair of sides, a first end and a second end, an inlet and an outlet for a first fluid, and an inlet and an outlet for a second fluid, the sides extending parallel to a longitudinal axis;
(b) a first mounting arrangement for securing the first end of the core to a first surface;
(c) a second mounting arrangement for securing the second end of the core to a second surface, wherein the second mounting arrangement comprises a pair of planar extensions located proximate to the second end of the core, each of the planar extensions being rigidly secured to one of the sides of the core and extending outwardly from the side to which it is secured;
(d) a mounting bracket for securing the second end of the core to the second surface, wherein the mounting bracket has a central portion and a pair of edge portions attached to the central portion and projecting therefrom,
wherein the central portion is adapted to cover a portion of the top of the core proximate to the second end thereof, and has a width sufficient to extend across the top of the core;
wherein, with the central portion covering said portion of the top of the core, the edge portions project outwardly from opposite sides of the central portion and from opposite sides of the core, with each of the edge portions being substantially parallel to one of the planar extensions;
wherein each of the edge portions has a top layer with a width sufficient to at least partially cover one of the planar extensions with the central portion covering said portion of the top of the core, and wherein each of the edge portions is adapted to be secured to the second surface;
wherein the central portion of the mounting bracket has a top surface and a bottom surface, and wherein the bottom surface is adapted to engage the top of the core with the central portion of the mounting bracket covering said portion of the top of the
