A resilient sealing mount seals the frame core connection, accommodates the locators and damps vibration between the frame and core.

Description

Z(~4 Description ~eat Exchanger Core Mounting ~pparatus Technical Field This invention relates generally to heat exchange and more particularly to positioners for assembly and retention of heat exchanger apparatus.

Background Art Heat exchangers and radiators, and particu-larly the type of radiators used to cool internal combustion engines, either on a moving vehicle or on a fixed stationary frame, have usually been constructed as single integral units. In addition, such heat exchangers and radiators have been constructed by mounting a plurality of cooling cores between a pair of spaced inlet and outlet tanks or by connecting the cooling cores together by hoses. These cooling cores include tubes having fins radiating orthogonally there-from and provide a means for conducting a fluid coolant from the circulating system of the engine to flow from the inlet tank, through the tubes, and into the outlet tank. Air flow, often created by a fan or movement of the vehicle, passes through the radiator to absorb heat from the radiating fins thereby reducing the temperature of the fluid coolant flowing through the tubes.
2~ The heat absorbing air flow often carries debris which clogs and damages the cores. Various attempts have been made to avoid such clogging and damage including arranging multiple core modules angu-larly in a core mounting frame with respect to air flow in slotted "V" shaped pairs so that the debris is deflected from one of the core races and directed through the slots. These cores are rotated after a
3~

Z~04 period of use to expose an unabraded core face to the debris laden air flow.
One limitation is that it is costly and time consuming to locate the cores at the proper angular relationship in the first instance and then to locate them again when the cores are rotated. Thus there is a need for a suitable locating means which provides both initial location and rotated location. Previously, the core modules and the inlet/outlet tanks were connected by two fluid coolant carrying tubes at each end of the module. Connection of the tubes provided the desired angular relationship of the module to the air flow.
However, these multiple tube connections increased the possibility of leakage of the coolant.
Recognizing that vehicle frames vibrate and distort during operation, the radiator cores have in the past been resiliently mounted in some manner to prevent rupture and leakage of the radiator cores which might otherwise occur if the cores were rigidly attached to the frame or to the manifold. A resilient mounting seal has been provided to limit vibration and seal against leakage. However, another limitation would be to provide a suitable resilient mounting seal which could accommodate the suitable locating means and provide a beneficial seal between the core and the multiple tube connections.
The foregoing illustrates limitations of the known prior art. Thus, it is apparent that it would be advantageous to provide an alternative to the prior art. Accordingly, the present invention is directed to overcoming one or more of the limitations as set forth above.

Disclosure of Invention In one aspect of the present invention, this Z2()4 is accomplished by providing a heat exchanger com-prising first and second frame members each having a bore therein; a core extending between the frame members and having first and second opposed end portions, each end portion having a spout extending outwardly into the bore of the adjacent frame member;
resilient means for resiliently and sealingly sup-porting the core between the frame members, said resilient means including a pair of resilient pads each positioned between one of the end portions and the adjacent frame member; and means for locating the core in a predetermined registraton with the frame members, said means including an imperforate protuberance extending outwardly from one of said first end portion and said first frame member and spaced from the spout, and an imperforate recess in the other of said first end portion and said first frame member and being in registry with the protuberance, said one resilient pad positioned between said first end portion and said first frame member having a portion resiliently accom-modating the protuberance and the recess.
The foregoing and other aspects will becomeapparent from the following detailed description of the invention when considered in conjunction with the accompanying drawings. It is to be expressly under-stood, however, that the drawings are not intended as adefinition of the invention but are for the purpose of illustration only.

Best Mode for Carrying ~ut the Invention A heat exchanger core mounting apparatus is designated 10, Figure 1, and comprises a core supportina frame which includes a pair of spaced apart inlet and outlet header plates 12,12a. A main inlet tank 14 is secured to adjacent inlet plate 12 by bolts 15 and a main outlet tank 14a is secured to adjacent outlet plate 12a by bolts 15a. A plurality of core modules, including but not limited to 16,16a,16b, are mounted between plates 12,12a and are located in angular rela-tionship with respect to an air flow as indicated by an arrow designated 18, see also Figure 6. Thus, air flow passes across an upstream side 20 of plates 12,12a, through core modules 16,16a,16b and across a downstream side 22 of plates 12,12a.
Means 24 are provided for locating core modules 16,16a,16b in predetermined registration with plates 12,12a. By predetermined registration is meant that core modules are located generally in "V" shaped pairs (Fig. 6) so that one edge 26 of each core 16,16a, 16b is adjacent upstream side 20 of plates 12,12a and another edge 28 of each core 16 is adjacent downstream side 22. The upstream edges 26 of adjacent cores are in close enough proximity to resist flow therebetween.
However, the downstream edges of adjacent cores are inclose proximity to permit air flow therebetween in such a manner that a slot 30 is formed of a sufficient size to permit the passage of debris therethrough. The means 24 for locating preferably includes first and second locating members such as detents 32 formed in plates 12,12a and corresponding protuberances 34 formed on each core 16.
Means 36 are provided for sealingly and resiliently mounting each core 16,16a,16b with plates 12,12a. One of such means 36 is between an inlet end 38 of core 16 and inlet plate 12 and another of such ll;~;~ZQ~

means 36 is between an outlet end 40 of core 16 and outlet plate 12a in a manner so as to accommodate locating means 24.
Plates 12,12a, Figures 1 and 6 are generally well known and, in accordance with this invention, plates 12,12a include apertures 42 and also include the plurality of first locating members or detents 32 adjacent upstream side 20 and adjacent downstream side 22. A plurality of connector bars 13, which do not inhibit air flow, may be used to interconnect plates 12,12a.
Cores 16,16a,16b are also generally known and, in accordance with this invention, include a plurality of tubes 44 having a plurality of very closely spaced cooling fins 46 radiating orthogonally there-from. A core inlet tank 48, see also Figures 2 and 5, is at inlet end 38 of core 16 and a core outlet tank 50 is at outlet end 40 of core 16. Tanks 48,50 each include an aperture or spout 52 provided for extending into aperture 42 of plates 12,12a and also include at least one, and preferably a pair of, second locating members such as protuberances 34 spaced equidistantly from spout 52. Spouts 52 of each core 16,16a,16b lie on a common axis which, in the form illustrated, is the vertical geometric centerline or longitudinal axis ofthe core. In this manner each core 16,16a,16b is pivotally mounted between plates 12,12a by virtue of spouts 52 being a pivotal axis. Protuberances 34 are of a construction sufficient for engagement with detents 32. As best illustrated in Figures 1 and 6, a pair of protuberances 34 engage a pair of detents 32, one of the protuberances 34 and engaged detents 32 being adjacent upstream side 20 and another of the protuberances 34 and engaged detents 32 being adjacent downstream side 22 for securing any of the cores 16,16a,16b, or Z2~)~

others, in the desired predetermined registration with plates 12,12a. More specifically, detents 32 are located in a predetermined registration so that when engaged by a given pair of protuberances 34 on a given core 16,16a,16b, etc., edge 26 of core 16a, for example, is in flow resisting proximity with adjacent core 16b at upstream side 20 and edge 28 of core 16a is in flow permitting proximity with adjacent core 16 at downstream side 22 forming slot 30. Protuberances 34 can engage either the upstream or downstream detents 32 when core 16 is rotated 180 degrees so that either edge 26,28 is adjacent upstream side 20 or downstream side 22 for exposing either one of the similar opposed faces 68 (only one of which is shown in Figure 1) of core 16.
Means 36, see also Figures 3 and 4, comprises a generally known inlet resilient mounting member 54 and an outlet resilient mounting member 56, each member including a single lip 58 for sealing between aperture 42 and spout 52 and peripheral resilient mounting strip 60. In accordance with this invention, each member includes resilient locating detent pads 62 formed to accommodate protuberances 34 on one side 64 and to accommodate detents 32 on another side 66. As illus-trated in Figure 1, inlet resilient member 54 is between core inlet tank 48 and inlet plate 12, whereas outlet resilient member 26 is between core outlet tank 50 and outlet plate 12a. Apertures 70 are formed through pads 62 to limit air entrapment between detents 32 and protuberances 34.
Industrial APplicability With the parts assembled as set forth above, hot fluid is introduced into main inlet tank 14 and then flows downwardly through the tubes 44 of core 16 and into the main outlet tank 14a. The fluid is cooled in ll;~ZZ~34 the core 16 in the usual manner. As the fins 46 on faces 68 of the core 16 which are receiving air flow are erroded or abraded due to sand particles and the like in the air flow it may become necessary to rotate the core 16. One can first remove main tank 14, loosen or remove bolts 15 and partially separate the core 16 from the input plate 12 and the output plate 12a and rotates core 16, in place, 1~0. The entire assembly is then positioned back in place. Generally, the resilient means 36 will not be rotated but will be left affixed to the core 16.
The present heat exchanger structure is useful for cooling internal combustion engines such as are used in vehicles and in stationary installations.
The possibility of leakage is minimized by providing only a single fluid communication between each core 16, its inlet plate 12 and its outlet plate 12a. The entire core 16 can be rotated relative to the plates 12 and 12a without disassembly of the apparatus 10.
The foregoing has described a heat exchanger core mounting apparatus which is sealingly and resiliently mounted in a frame and locates the core in predetermined registration with the frame.
It is anticipated that aspects of the present invention, other than those specifically defined in the appended claims, can be obtained from the foregoing description and the drawings.
