Definitions

• This invention relates generally to heat exchange and more particularly to .positioners for • assembly and retention of heat exchanger apparatus.
• 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.
• 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 tempe'rature of the fluid coolant flowing through the tubes.
• 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 faces and directed through the slots. These cores are.rotated after a period of use to expose an unabraded core face to the debris laden air flow.
• radiator cores 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.
• 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.
• OM ⁇ ,- WIP is accomplished by providing a heat exchanger core mounting apparatus including means for locating tKe heat exchanger core in predetermined registration vwith a frame member.
• the invention also includes means for sealingly and resiliently mounting the core in the frame which accommodates the locating means.
• Figure 1 is a frontal cross-sectional view illustrating an aspect of the present invention as applied to one of a plurality of radiator core modules as viewed along lines I-I of Figure 6;
• Figure 2 is an isometric view illustrating a portion of a core module having a pair of locating' means of this invention;
• Figure 3 is a top planar view illustrating a resilient member of this invention
• Figure 4 is a side elevational view in partial cross-section illustrating the resilient member as viewed along lines IV-IV of Figure 3;
• Figure 5 is a side elevational view illustrat ⁇ ing the locating means as viewed along the lines V-V of Figure 2;
• Figure 6 is a top view illustrating the angular relationship of adjacent core modules of this invention as viewed along the line VI-VI of Figure 1.
• 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.
• ai-r 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.
• 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.
• the downstream edges of adjacent cores are in close 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 fdrmed 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
• - O eans 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.

• 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 of the 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
• detents 32 are"-' located in a predetermined registration so that wt ⁇ en 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 down ⁇ stream 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.
