ENGINE COOLING SYSTEM Farrile S. Young, Kansas City, Mo., assignor to Panhandle Eastern Pipe Line 00., Kansas City, Mo., a corporation of Delaware Application April 21, 1948, Serial No. 22,415

2 Claims.

particularly to a cooling system for the engines used in such compressors, and combines an arrangement such as shown in my Patent No. 2,424,010 issued July 15, 1947, for cooling the oil with an exhaust induced air flow for cooling the water whereby the combined cooling effect of the cooled oil and water maintain the compressor and engine at operating temperatures so they can operate for long periods without attention.

The principal objects of the present invention are to provide a portable type compressor having an arrangement for cooling oil and jacket water without use of any power; to provide devices applicable to both liquid and vapor stage cooling of the internal combustion engine used with the compressor; to provide a heat exchanger for cooling the oil from the engine of the compressor; to provide means for supplying gas from a source of supply to said heat exchanger for cooling the oil from the engine; to provide an air-fin type jacket water cooler for effecting the cooling of the jacket water; to provide means for exhausting gases from the motor from the engine to a venturi above the fin-type water cooler to induce flow of cool air through said water cooler, and effect heat transfer from the water to the air; and to provide a device which is simple, economical to manufacture and efiicient in operation for the purpose set forth.

In accomplishing these and other objects of invention, I have provided approved details of structure in the preferred form of which is illustrated in the accompanying drawing, wherein:

Fig. 1 is a perspective view illustrating my invention showing a part of the housing broken away to illustrate the air-fin type water cooler.

Fig. 2 is a longitudinal sectional view through the heat exchanger forming part of my invention.

Fig. 3 is a vertical cross-sectional view through the canopy and venturi above the housing, particularly illustrating the air-fin type jacket water cooler and the exhaust from the engine to the venturi.

Referring more in detail to the drawings:

I designates a field compressor embodying the features of my invention supported on skids or the like (not shown) for movement from place to place, if desired. 2 designates a housing for the compressor, having a sloping roof as indicated at 3. r

4 designates an engine of ordinary construction having a plurality of cylinders 5, an exhaust manifold 15, free air header 1 and a crank z case 8, adapted to contain lubricating oil for the motor. The compressor hasa plurality of chambers 9 each having connection with a heat exchanger l and a discharge. header ll, said discharge header carrying the compressed gas to the discharge side of a pipe line 12.. Leading from the inlet side of the line I2 is a pipe line l3 which connects to the heat exchanger as indicated at 14, Fig. 1, the line I3 supplying a source of gas to the heat exchanger. The heat exchanger is connected to the chambers 9 by pipes l5.

The heat exchanger preferably consists of a cylindrical shell. I! provided at the respective ends with heads 18, having a plurality of openings and receiving a plurality of tubes l9 around which gas entering from pipe 1 3 will pass through the heat exchanger, to pipe lines I5 to the compressor chambers 9. The tubes l9 may be attached to the heads .18 by swaging or other suitable means. A closed header is attached to one end of the heat exchangerand a header 2| is attached to the opposite end having a partition 22 forming compartments 23 and 24. Leading from the compartment 23 of the heat exchanger is a line 25 having its opposite end connected to the crank case 4 asindicated at 26.. A line 27 leads from the compartment 24 of the header 2| of the heat exchanger and .has its opposite end connected to a pump 28 which also connects to the crank case 4 as indicated at 29.

I also preferably provide a fuel gas line 30 leading from the gas line I2 to the motor 4 as indicated at 3| for supplying. fuel thereto,

Suitably supported on and spaced above the roof 3 as by posts 32 i a canopy 33 comprising a frame 34 and upwardly and inwardly sloping walls or top 35 terminating in a circular housing 36. The housing 36 has a tapered top 31 having an opening 38 for a stack 39. The stack .39 is provided with a restricted portion 'forming a venturi 40.

Located within the framework 34 and extending longitudinally thereof are a plurality of tubes 4| forming a radiator for water for the engine. The radiator is here illustrated as consisting of two rows of tubes, one above the other, through which the water from the engine flows for cooling of such water before returning to the engine.

A line 42 is connected with said tubes and has its opposite end connected to a chamber 43 of the engine 4 as indicated at 44. A line 45 is attached to the upper side of said tubes and leads to the engine 4 for return of water to the engine after it has been cooled. A pump 46 is connected to the Water chamber of the engine for circulation of the water.

A line 4! is connected to the exhaust manifold 6 of the engine and has its upper end extending through an opening 48 in the housing 36 and its end turned upwardly forming a nozzle aligning with the venturi in the stack 39 as indicated at 49.

Operation of a device constructed and assembled as described is as follows:

Gas is supplied from lin I2 from a source of supply (not shown) and line 30 leads :from such line to the engine for supply of fuel gas for operation of the engine. Gas alsofrom the source of supply from line l2 enters the heat "exchanger through line I3 usually at a comparatively low temperature and passes around the tubes l9 in the heat exchange. case by pump 29 through line 21 to the heat exchanger and passes through tubes l9 cooled by the gas and :is for'ce'd back through the line .215 leading :back to the crank case, the oil being cooled as it passes through the cooled tubes in the heat exchanger. .Aft'erthe gaspasses through the heat exchanger, it is returned to line I2 through line I leading from the chambers 9 of the compressor.

The canopy .33 is spaced a sufiicient distance from the :roof 3 .so that vair will pass upwardly around the tubes 4:! in the canopy and thence upwardly through 'thetapered tp'35 to housing 36. The exhaust gas jet from the engine passes through tube 41 to the housing :and the nozzle thereof being in alignment with the venturi 49 of the stack w ill ca'use an increased situation-of air through said venturi and thus efiectsa flow of .air upwardlyaroun'd the tubes 41 to cool said tubes withf-air zfrom atmosphere, thus cooling the water from the engine. After the water has passed through the tubes and is cooled itis returned to th zengine through line 45.

WhileJIThav e here shown'the water-cooling system located above the compressor it will "be .obvious it may be located to the side or at "any convenient pla'ce adjacent the compressor.

It will be 'obvious from the foregoing that .I have provided an improved coolin system structure if'or afield compressor and cooling of the oil and water :for the engine without extraneous sources.
