ARTHUR B. MODINE, OF RACINE, WISCONSIN, ASSIGNOR TO MODINE MANUFACTURING COMPANY, OF RACIN'E, WISCONSIN, A CORPORATION OF WISCONSIN HEAT EXCHANGE DEVICE Application filed March 25, 1927. Serial No. 178,490.

My invention relates to heat exchange. device and has among its other objects the production of apparatus of the kind described which is convenient, compact, durable, efficient and satisfactory for use wherever found applicable.

A particular object of the invention is to provide improved ,apparatus for cooling compressed gases, or the equivalent.

In one embodiment of the invention animproved heat exchange device is interposed between a plurality of compressors in such manner that compressed air is delivered to the heat exchange device from one of the compressors and is then cooled therein before it is delivered to the second compressor which again compresses it. The improved cooling device preferably comprises a plurality of spaced tubes through which the compressed air is passed so that there will be an efficient exchange of heat between the compressed air and a column of air which is advanced around the tubes by a fan, or the equivalent.

Another substantially the same apparatus as that described in connection with the first-men tioned form of the invention but in addition, also comprises means for cooling the coolingwater which is circulated t rough the cylinder jackets of the compressors.

Many other objects and advanta es of the construction herein shown will be obvious to those skilled in the art from the disclosure herein given.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims.

In the drawings, wherein like reference characters indicate like or corresponding parts: i

Fig. 1 is an elevation of apparatus embodying one form of the invention; and

Fig. 2 is a section taken on line 2-2 of Fig. 1.

The reference characters 52 and 53 desigj nate compressors which, in this instance, are of the double acting type and are adapted to form of the invention comprises compressor cooperate to compress air at atmospheric pressure to a relatively high pressure, the air being passed through a radiator unit 54 formed of a heat exchange device 55 which also comprises a radiator unit 56. The radiator unit 54 comprises spaced tanks 57 and 58 which communicate with each other through a plurality of tubes 59 and the radiator unit 56 preferably comprises spaced

tanks

60 and 61 which communicate with each other through a plurality of spaced tubes 62. The spaced

tubes

59 and 62 may be of any suitable construction but are preferably formed from relatively thin sheet metal and are preferably provided with cooling fins or flanges 64 soldered in header plates 66 which are formed with integral flanges 67 soldered in grooves 68 formedin the

tanks

57, 58,60 and 61. The tank 61 is preferably secured by bolts 69, or the equivalent, to a frame member 70 and the tank 62 is referably secured by bolts 72, or the equiva ent, to a frame member 73, the tanks 58 and 60 being preferably secured by bolts 75, or the equivalent, to a frame member 76 disposed intermediate the

aforementioned frame members

70 and 73. The frame members 7 0, 73 and 76 are preferably rigidly secured to each other by means comprising side plates 77 which cooperate with the frame members to form a chamber 78 in which a fan 79 and an electrical motor 80 are positioned, the fan 79 being secured to the shaft of the motor 80. Secured to the frame member 73 is a bracket 81 which carries the motor 80.

The exhaust ports of the compressor 52 communicate with a pipe fitting 83 which is connected by pipes 84 and 85 and an elbow fitting 86 to the tank 60 and the intake openings of the compressor 53 are connected to the tank 61 by a pipe fitting 87, an elbow fitting 88 and a pipe 89, theexhaust ports of the 53'being adapted to discharge the air into a pipe fitting 90 so that it may be delivered to any suitable apparatus.

The compressors 52 and 53 comprise

water jackets

92 and 93, respectively. The water 'acket 92 is connected to the tank 57 by an elbow fitting 94 and

pipes

95 and 96 and the water jacket 93 is connected to the same tank compressed by a pipe 98, an elbow fitting 99 and a pipe 100. The water jacket 92 is operatively connected to the tank 58 by suitable elbow fittings and pi es which are identified generally by the re erence character 105 and the water jacket 93 is connected to the same tank by suitable elbow fittings and pipes which are identified generally by the reference character 104.

The operation of the apparatus is substantially as follows: Assuming that the motor 80 has been operatively connected to a source of electrical energ it is obvious that the fan 79 will rotate an advance a column of air through the space between. the

tubes

59 and 62. Now, if the compressors 52 and 53 are set in operation, the compressor 52 will take in air at atmospheric pressure and after compressing it, discharge it into the tank 60. This compressed air will then pass through the tubes 62 into the tank 61 and thence through the pipe 89, the elbow fitting 88 and the pipe 87 into the compressor 53 which'discharges it at a higher pressure into the pipe fitting 99 which is, of course, connected to any suitable apparatus. When the air is first compressed in the compressor 52, its temperature rises and when it passes through the tubes 62 there will be an exchange of heat through the walls of the tubes so that the compressed air will be cooled. This cooled air is then delivered to the compressor 53 which again compresses it and causes a rise in its temperature. However, the compressed air discharged from the compressor 53 will have a relatively low temperature.

Now, if it is assumed that the

water jackets

92 and 93 and that the radiator unit together with the pipes which connect the radiator unit with the water jackets are entirely filled with' water, it is readily under-.

stood that when'the compressors 52 and 53 are again in operation, a thermo-syphonic action will be set up which will cause heated water from the

water jackets

92 and 93 to flowupward in the

tubes

95 and 98 to be delivered into the tank 57. This water will descend through the tubes 59 and be cooled by the column of air advanced by the fan 42. The cooled water is returned to the water jackets by way of the pipe fittings 1 04 and 105.

It will be noted that the heat exchange device 54 is substantially unitary in construction and that a single or common means is employed to advance a column or air through the space between the

tubes

59 and 62.

. Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and 55 described, or uses mentioned.

What I claim as new and desire to secure by Letters Patent is:

1. A heat exchange device comprising a pair of spaced tanks, a set of spaced tubes connecting said spaced tanks to each other, a second pair of spaced tanks disposed in substantially the same plane as the first-mentioned pair of spaced tanks, a second set of spaced tubes connecting the second pair of s aced tanks to'each other, each pair of tanks eing formed with intake and discharge openings, and common means for advancing air, through the spaces between said first and second sets of tubes, said means being connected for support with said tanks and tubes.

2. A heat exchange device comprising a radiator unit, a second radiator unit disposed in substantially the same plane as the firstmentioned radiator unit, said radiator units being provided with intake and discharge openings whereby fluidsmay be circulated therethrough, and common means including rotatable means, the axis of rotation thereof being arranged in a plane transverse to the plane of said radiator unit for subjecting said radiator units to a flow of air to effect an exchange of heat between said fluids and said air, said radiator units being mounted substantially as a single unit on one side of said last named means.

3. A heat exchange device comprising a radiator unit, a second radiator unit disposed in substantially the same plane as the firstmentioned radiator unit, said radiator units being provided with intake and discharge openings whereby fluids may be circulated therethrough, and a fan located in a plane which is substantially parallel with said last mentioned plane for subjecting said radiator units to a flow of air to effect an exchange of heat between said fluids and said air, said radiator units being mounted substantially as a single unit on one side of said fan.
