AIR COOLER I Filed Sept. 2, 1959 Patented July 9, 1940 narran stares PATENT GFFECE 2 Claims.

This invention relates to air coolers, and it is a particular object of the invention to provide a device of this kind to be placed within an enclosed body of a truck or the like to maintain the air within said body at a relatively low temperature.

It is also an object of the invention to provide a device of this kind comprising a box containing the desired cooling medium, such as ice, and wherein means are provided for causing air Within the body of a truck or kindred chamber to travel in a tortuous path thru the box for discharge within the box or chamber.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved air cooler whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be denitely claimed.

t In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawing wherein Fig. 1 is a view partly in vertical section and partly in elevation illustrating an air cooler constructed in accordance with an embodiment of my invention, the line of section being substantially on the line I-I of Fig, 2.

Fig. 2 is a transverse sectional View on substantially the line 2--2 of Fig. 1.

My improved device as herein disclosed comprises a box B of desired dimensions and which is adapted to be placed within the enclosed body of a truck or other chamber and adjacent to an end wall of such body or chamber. The ytop portion of the box B at one end thereof and at a point at substantially its center is provided with the transversely disposed flat members or panels I and 2. The space between the panels I and Z is adapted to be closed by a removable door 3 while the space between the member or panel 2 and the end of the box B remote from the member or panel I is adapted to be closed by the door 4. The doors 3 and 4 provide means whereby ice may be readily placed within the box B.

Extending upwardly from the member or panel 2 is a riser pipe 5 which is preferably of a length to closely approach the top or roof of the closed body or chamber. The upper end of the riser pipe 5 is continued by a horizontally disposed vpipe or conduit 'I of a length to terminate at approximately the center of the body or chamber. The outer end portion of this pipe or conduit 'I is provided with a discharge nozzle herein disclosed as of a type to dischargethe air therefrom in diverging streams. It is to be stated at this time, however, that insofar as the present invention is concerned, the exact location of the nozzle with respect to the body or chamber in which it is positioned forms no essential partof the invention as such nozzle may be positioned where it is believed the best results can be obtained.

Extending within the box B thru the member or panel I is a desired number of air intake pipes 8. kThe lower end portion of each of these pipes 8 is in communication from above with a manifold 9 of desired length and preferably of a length to substantially bridge the space between the side walls IIB of the box B but spaced therefrom suiciently to allow ice water or brine to substantially completely surround the manifold. The inner wall II of the manifold 9 has in communication therewith a plurality of spaced parallel ues IZ'arranged side by side 'and which also communicate with a second manifold I4 thru the inner wall I5 thereof. This manifold I 4 also extends substantially entirely from one side wall II) of the box B to the other. The manifold I4 is of 'a size' to vdepend a material distance below the iiues I2 and the'manifold I4 below the flues I2 has in communication therewith thru its inner wall I5 a lsecond series of flues I6. Theseues I6 are in parallelism and are arranged side by side in such spaced relation whereby the flues I2 and I6 are staggered. 'Ihe flues I6 are also in communication with a manifold I'I thru the inner wall I8 thereof. 'I'his manifold I'I is positioned below the manifold 9 f and is of substantially the same length as the manifold 9. l

Underlying the manifolds I4 and the iiues IIS is a duct I9 of a width substantially equal to the widths of the manifolds I4 and II. One end portion of the duct I9 is in communication, as at 20, with the manifold I1 thru the bottom wall 2| thereof. The duct I9 at its extremity remote from the manifold I1 is continued by a vertically disposed duct 22 which passes between the manifold I4 and the adjacent end wall 23 of the box B. This vertical duct 22 extends a desired distance above the manifold I4 and has vcommunication with a fan housing 24 thru the bottom wall 25 thereof. Suitably supported within the opposite end I l and also portions of the housing 24 are the suction fans 26 of a conventional type and driven in any manner desired altho it is preferred that the same be driven by an electric motor in communication with a battery or other suitable source of electrical energy.

The fans 26 include discharge nozzles 21 which extend out thru the inner Wall 28 of the housing 24 and discharge within the upper portion of the box B.

It is to be pointed out that the flues l2 and I6 are each in cross section in the form of an inverted V. This allows for quick chilling and by having i the ues I6 in staggered relation allowance is made for all of the flues to have close contact with the ice as the ice melts and drops.

It is also to be pointed out that the arrangement of the flues l2 and I6 together with the ducts I9 and 22 is such as to assure quick chilling of the air as it is drawn therethru by the fans 26. By having the nozzles 21 discharge within the upper portion of the box B the melting of the ice within the box B is sufficiently retarded to render the use of the apparatus highly economical.

It is further to be stated that the closure members or doors 3 and 4 when applied effect airtight closures and it is to be pointed out that the eiciency of the apparatus is further increased by having the fans 26 contained within the housing 24.

From the foregoing description it is thought to be obvious that an air cooler constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason'I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

I claim: 1. An air cooler comprising an enclosed box, a

discharge pipe leading from the upper portion of the box, two manifolds in one end portion of the box, one of said manifolds being positioned above the other, a single manifold in the opposite end portion of the box, flues interposed between and connecting the uppermost of the rst named manifolds with the single manifold, ues connect ing the single manifold with the lower of the rst two manifolds, the upper of the first two manifolds being in communication with the outside atmosphere, a duct underlying the second named flues and in communication with the lower of the rst named manifolds, said duct being continued by a vertically disposed duct, a housing within the upper portion of the box with which the vertically disposed duct communicates, and a suction fan within the housing for drawing outside air thru the manifolds, flues and ducts and delivering such air within the upper portion of the box for discharge thru the discharge pipe.

, i 2. An air cooler comprising an enclosed box, a
