REFRIGERATOR CONSTFUCTION.

' Application filed February 16, 1928. Serial No. 88,630.

. This invention relates to a wall construction, the general object of the invention being to form a wall with conduits which form passages for fluids by attaching a corrugated sheet to a flat sheet or plate, the space formed by each corrugation and that portion of the flat sheet which extends across the corrugation constituting the conuit.

Another object of theinvention is to provide manifolds which are connected to the upper and lower parts of the wall to conduct fluid to the conduits and to receive the fluid from the conduits.

-Another object of the invention is to so position a pair of walls that 'a. vacuum chamber may be formed between them, this construction being designed to be used as a in the sides of the casing, ad acent the top combined cooler and condenser.

This invention also consists in certain other features of construction and in the combination and arrangementof the several parts, to be hereinafter fully described, il-' lustrated' in the accompanying drawings 2 and specifically pointed out in the appended claim. c In decsribing my invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which y p Figure 1 is an elevation, with parts broken away, showing the simplest form of the invention.

Figure 3 is a section on line 3-3 of Figure 2. Fi re 4 i'sa view similar to Figure 1, but 'showmg a slight modification.

Figure 5 is a section on line 5-5 of Figure 6.

Figure 6 is a section online 6-6 of Fig- Figure 2 is a section on line 2-2 of Fig-- the casing, these hoods forming inlet andoutlet manifolds and fluid is conducted to the inlet manifold through the conductor pipe 5 and after flowing through the conduits, it asses into the outlet manifold and escapes t rough the exhaust pipe6.

In Fi res 4, 5 and 6, holes 7 are formed and bottom thereof and these holes communicate with the conduits and in this case the manifolds 8 are fastened to the sides of the casing and cover the holes so that fluid the holes 7 into the conduits and willflow from the conduits through the holes 7 at the other end of the device into the discharge manifolds.

Figures 7, 8 and 9 show a pair of devices, such as shown in Figures 4, 5 and 6, arranged in spaced relation'to form a central chamber 9 which is closed by the stri 10 which is connected with the edges 0 the devices, as shown in Figures 8 an 9. Spacing members 11 may be placed in the chamber between the two devices, as shown in Fi re 9. 4

igures 10 and 11 show the openings leading to and from the conduits as formed by cutting away the'ends of the straight plates, as shown at 12, and covering these parts by the manifold forming extensions-13 of the caps 14 which form the ends of the casing.

,By cutting away the straight plates, the

ends of the conduits formed'b the corrugated plate and the straight'p ates are exposed, so that fluid entering the manifolds 13 will flow into the conduits. The discharge end of the device is similarlyformed so that the fluid will flow from the conduits into the discharge manifolds.

Figures 12 and 13 show the corrugated will pass from the inlet manifolds through member 1 as made with rectangular corrugations, Figure 12 showing a pair of flat the corrugated member 1 provided with V- shaped corrugations.

From the foregoing it will be seen that I have provided means for forming conduits in a wall or casing so that the structure can be manufactured very chea ly, and the structure is mainly designed or use in refrigeratin systems, the conduits being used for the re ri erating or other fluids. Some of the conduits can be used for the refrigerating fluid and others for the fluid to be cooled.v Of course, the structure could be used with a heating fluid or as a heat exchanger. Where two difi'erent fluids are used, the structure must be used which is provided with a pair of inlet manifolds and a air of outlet manifolds.

or application to ice boxes, ice cream containers, transformers, or other places where heat is to be exchanged between the outside and inside of a vessel, room or cabinet for heating or cooling, the structure can be made to form the container itselfand the insulation.

In the form shown in Figures 7, 8 and 9 the structure can be used as a cooler an condenser with the central chamber form;

vacuum chamber can'be formed between one as that shown in Fi I members 11 should placed'at-right angles to the conduits and should be formed of.low

heat'conducting material. These members separate the elements and form the vacuum spaces and these members and the-corrugated construction will support the parts of the device against atmos heric pressure. By polishing the inside sur aces and using the vacuum, a high heat insulation will be secured. v v

It is thought from the foregoing description that the advantages and novel features of my invention will be readi1y apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall withm the scope of the appended claim. What I claim is The herein described structure, comprising a casing, a corrugated sheet ,therein having its outer portions connectedwith the "walls of the casing to form two sets of conduits, the said casmg having openings in its side walls adjacent the top and bottom thereof which communicate with the conduits audrfluid inlet and discharge'manifolds covering the openin In testimony whereof ture. v 7
