TECHNICAL FIELD This invention relates generally to heat exchangers, and more particularly to positioning devices for assembling and retaining heat exchange devices.

BACKGROUND OF THE INVENTION Heat exchangers and radiators, particularly of the type used to cool engines mounted on moving vehicles or on fixed stationary frames, are commonly constructed as a single combined unit. Further, such heat exchangers or radiators may be constructed by mounting a plurality of cooling cores between a pair of spaced inlet and outlet tanks, or by connecting the cooling cores with hoses. consists of things. The cooling cores include tubes with orthogonal heat dissipating fins and form a device for conducting cooling fluid from the engine's circulation system from the inlet tank, through the tubes, and into the outlet tank. do. Typically, airflow created by a fan or vehicle running passes through a radiator and absorbs heat from the heat dissipating fins, thereby lowering the temperature of the cooling fluid flowing through the tubes.

The heat-absorbing air stream often contains dust, which often clogs and damages the core. Various attempts to prevent such clogging and damage have been proposed in the past, and some of these attempts include a method to connect a large number of core modules mounted in a core mounting frame to one pair. Some are arranged in a slotted "V" shape with respect to the airflow, and deflect dirt from one core surface and direct it through the slots. After a period of use, the cores are rotated so that the unworn core surface faces the dust-laden air stream.

One disadvantage of this is the high price, and the fact that the cores are initially positioned in precise angular relationship,
Another problem is that it takes time to reposition the core after rotating it. A suitable positioning device is therefore required both for initial positioning and for positioning after rotation. In the past, the core module and inlet/outlet tank were connected by two cooling fluid carrying tubes at each end of the module. Such tube connections set the module in the desired angular position relative to the airflow. However, such numerous tube connections increase the possibility of cooling fluid leakage.

Considering that the frame vibrates and distorts while the vehicle is in operation, radiator cores have traditionally been mounted with some degree of elasticity to prevent breakage and leakage that would occur if they were rigidly mounted to the frame or manifold. There is. Resilient mounting seals were used to dampen vibrations and seal leaks. However, there is the additional drawback of having to create a suitable resilient mounting seal that is compatible with a suitable positioning device and that can provide an effective seal between the core and the manifold joint.

The above are the shortcomings of the prior art. Therefore, it goes without saying that it is advantageous to make improvements to such conventional techniques. It is therefore an object of the invention to eliminate the above-mentioned disadvantages.

DISCLOSURE OF THE INVENTION According to one aspect of the invention, it is an object to provide a heat exchanger core mounting apparatus comprising an apparatus for positioning a heat exchanger core in a predetermined alignment relative to a frame member. It is achieved by doing. The positioning device includes at least one member extending outwardly from either the core or the frame member.
leakage by providing two imperforate protrusions and a pair of imperforate indentations associated with said protrusions on the other of the core or frame members, and providing a single port in fluid communication between each core and frame member. The entire core can be rotated 180° about the axis of the mouth relative to the frame member, minimizing the possibility of The present invention also includes a device for sealingly and elastically mounting the core within the frame member, and the mounting device has an elastic pad between the core and the frame member, and the pad is not recessed. The projections are resiliently received to properly position the core in a predetermined relationship with the frame member.

These and other features will become apparent from the detailed description of the invention that follows in conjunction with the accompanying drawings. However, it should be understood that these drawings are not intended to limit the invention, but are merely illustrative.

This means positioning the core modules in pairs in a generally "V" shape, with the other edge 28 adjacent the upstream side 20 of the core module and the other edge 28 adjacent the downstream side 22 of the core module. The upstream edges 26 of adjacent cores are closed close enough to resist flow between them. However, the downstream edges of adjacent cores are placed in close proximity to permit flow between them, thus forming a slot 30 sized to permit passage of dirt between them. Positioning device 2

A pair of protrusions 34 engage a pair of solid recesses 32 in FIGS. 1 and 6. In FIGS. Thus, one protrusion 34 and the unperforated recess 32 that engages with it are closer to the upstream side 20, and the other protrusion 34 and the unperforated recess 32 that engages with it are closer to the upstream side 20.

and the downstream side 22, thus allowing any one of the same sides 68 (only one shown in FIG. 1) of the core 16 to be directed toward the airflow.

The apparatus 36 shown in FIGS. 3 and 4 includes a well-known inlet elastomeric mounting device 54 and an outlet elastomeric mounting member 56, each of which is used to provide a seal between the aperture 42 and the mouth 52. 58 and a peripheral elastic mounting strip 60.
