1941- F. M. YOUNG I I COMBINATION OIL AND WATER COOLER Filed May 17, 1959 m s/y TOR G N y vmw m mm r B 3 w. F

Patented Dec. 2, 1941 v Fred M. Young, Racine, Wis. Application May 17, 1939, Serial No. 274,100

2 Claims.

The present invention relates to major and minor heat exchange cores formed in a single unit having means for simultaneously cooling the jacket fluid and the lubricating oil of-an internal combustion engine by means of a single fan. 5 1

Further objects of the present invention are to provide a minor oil cooling core which is slidably mounted between unoccupied ends of the.

headers of the major unit and provide a device which will have the same general appearance of a single unit heat exchanger or radiator of the .conventional type and being adapted to be similarly positioned in its relation to the engine served.

Further objects of the present invention are to provide means whereby the oil cooling or minor unit may be conveniently removed from the assembly. and to properly proportion the size of the jacket water and oil cooling cores so the complete device is simple, efficient and pleasing in appearance.

In devices of the class, it will be understood that the temperature of the jacket fluid and lubricating oil will not always reach their normal operating temperatures simultaneously. I therefore provide means for independent expansion and contraction of the two units.

To these and other useful ends'my invention consists of parts, combinations of parts, or their equivalents, and mode of operation, as hereinafter described and claimed and shownin the accompanying drawing in which:

Fig. 1 is a front view of the preferred form of -my complete device, fractions being cut away.

Fig. 2 is a sectional view of the device taken on line 2-2 of Figure 1 and including the fan and fan shroud.

Fig. 3 is a fractional section taken on line 3-3 of Figure 1.

Fig. 4 is a top fractional view illustrating one manner of securing the oil cooling headers. to the headers of the jacket cooling device. I

As thus illustrated, I provide a unitary device comprising a major and minor unit, the major unit being designated in its entirety by reference character A and having a fan and fan shroud which in their entirety are designated by reference character B. The minor unit in its entirety is designated by reference character C. a

The major unit comprises header caps I and H, each having tube plates I! which are preferv ably removably bound and sealed to the caps connected together by means of a number of preferably flattened in cross section tubes l3 (see Figure 3). I provide a multiplicity of closely spaced fins [4 through which these tubes extend.

It will be noted that tubes I3 are nested together so they terminate as at l5 leaving a space between the headers for the oil cooling unit C. Unit C comprises headers l6 and i1 each having tube plates l8--l8 which are preferably 10 bound and sealed to the header caps as illustrated in the various figures.

Plates l8 are operatively connected together by means of a number of tubes I9 having a multiplicity of closely spaced fins 20 through which the tubes extend. Thus it will be seen that I'provide two separate heat exchange devices, one being considerably larger than the other and being provided with means whereby the unoccupied space between adjacent ends of the major headers provides room for the. reception of unit C.

Header I6 is provided with an inlet connection 2| and header I1 is provided with an outlet connection 22. These inlet and outlet connections may clearly be used in the reverse order.

Headers l0 and II are provided with inlet and outlet connections 8 and 9 and these headers may be provided with partitions 25 whereby the tubes are grouped so as to cause the fluid to pass through these groups in series. This feature however, forms no part of the present invention and is illustrated and claimed in a copending application, Serial No. 274,099, filed May 17, 1939.

A channel 23 rests over the upper ends of headers I0 and II, the flanges of which extend slightly below the upper edges of fins 20 (see Figure 3) thus to form a decorative top for the device and an anchor for the top of fan'shroud 30. i

0 Thus it will be seen that the lubricating oil of I the engine may be caused to travel through core C, and that the cooling fluid for the jackets of the enginemay be caused to flow through major core A as indicated by arrows.

Headers l6 and I! are preferably provided it Thus it will be seen that headers l6 and I1 may move slightly endwise and provide for unequal expansion and contraction between-tubes as illustrated. Tube pla es are operatively I3 and I9. Forexample, when the engine is first started, if the cooling fluid is heated more rapidly than the lubricating coil, then tubes B are free to expand faster than tubes IE or if the lubricating 011 should heat more rapidly than the cooling fluid, then tubes l9 are free to expand more rapidly than tubes l3. In either event, it will be seen that I have provided a simple and eflicient cooling fluid and lubricating oil heat exchanger and that the tubes of the cores are free to expand and contract independently. Clearly member C may be conveniently removed or replaced and the entire assembly will have an appearance similar to conventional Jacket cooling radiators.

It will be noted that fan shroud 30 will shield from view headers l6 and I1 and that this member may be secured to the unit similar to the shroud mounting of a conventionally designed radiator. Thus the rear view of the complete unit will be conventional. The front may, if desired, be shielded from view by means of a decorative grille.

It will be noted that tubes l9 are round in cross section whereas tubes l3 are flattened. The fluid pressure in a Jacket cooler core is very low and for that reason flattened tubes will answer the purpose better than round tubes. However, in a lubricating system, it is frequently necessary to operate under considerable pressure and for that reason I have shown the tubes in unit C as being round.

Having thus shown and described my invention, I claim:

finned tubes forming operating connections therebetween for the greater part of the length of the headers leaving a relatively narrow space between adjacent ends or the headers, a unitary oil cooler having spaced headers and finned tubes forming operating connections therebetween, said oil cooler adapted to lie within said relatively narrow space and having an overall length slightly shorter than the space between said first headers, the headers or said oil cooler being removably secured to said first headers and having means permitting independent free expansion and contraction relative to the space between said first headers.

2. A dual heat transfer device of the class described, comprising two spaced vertically positioned headers and finned tubes forming operating connections therebetween for the greater part of the length of said headers forming a Jacket liquid cooler but leaving a relatively narrow space between the upper ends of the headers, an oil cooler comprising spaced headers and finned tubes forming operating connections therebetween, the overall length of said oil cooler being slightly less than the space between said first headers and being removably and slidably mounted to thereby permit free expansion and contraction of the oil cooler relative to said 1. A dual heat transfer device of the class described, comprising two spaced headers and jacket liquid cooler, an inverted U-shaped channel secured to the tops of said vertical headers, its flanges extending downwardly, a fan having a shroud, two sides of said shroud being secured to said vertical headers and its top being secured to the adjacent flange of said channel.
