Patented June 14, 1949 COOLING PLATE Paul H. Brinkoeter, San Antonio, Tex., assigner to Ed Friedrich, Inc., San Antonio, Tex., a corporation of Texas Application July 19, 1946, Serial No. 684,968

1 Claim. 1

My invention, which relates generally to the art of refrigeration, particularly has for its objects:

1. To provide an improved cooling-coil-plate of such construction as to present a maximum cooling surface in a plate of a given length and breadth.

2. To provide an improved cooling-coil-plate which can be manufactured at a minimum cost.

3. To provide an improved cooling-coil-plate of any desired size for use either as the side and end walls of a refrigerator can such as is used in low temperature refrigeration, or as shelfplates in refrigerators generally.

Other objects will in part be obvious and in part be pointed out hereinafter.

To the attainment of the aforesaid objects and ends, invention further resides in the novel details of construction, combinations and arrangements of parts all of which will be first described in detail and then be specifically pointed out in the appended claims, reference being had to the accompanying drawings in which:

Fig. 1 is a face view of a cooling-coil-plate embodying my invention.

Fig. 2 is an enlarged detail section of the same on the line 2-2 of Fig. 1.

Fig. 3 is a face View of a cooling-coil-plate designed for use as a shelf.

Fig. 4 is a detail face view (parts being broken away) of a modi-cation of the shelf of Fig. 3.

Fig. 5 is an enlarged end elevation of the structure shown in Fig. 4.

Fig. 6 is an enlarged detail section on the line S-I of Fig. 4.

Fig. 7 is a schematic plan view of four of the plates of Fig. 1 arranged as the four sides of a can.

Fig. 8 is a schematic perspective view of the four sides assembled with a -bottom plate and a top flange.

In the accompanying drawings in which like numbers and letters of reference indicate like parts in all the gures, I represents the face sheet and Ia the back sheet of a cooling-coil-plate. The sheets are embossed to provide a plurality of parallel rows of series of embossings 2, 2a respectively, one row of a series of embossings 3, 3a respectively, and an inlet 4 and outlet 4a (Figs. 1 and 2).

The embossings 2, 2a, 3, 3a are all of the same length. The embossings 3, 3B respectively, lie in a direction at right angles to the direction of the embossings 2, 2a respectively.

The distance between the outer side edges of any two rows of embossings 2 or 2a is equal to the end to end measurement of one of the embossings 3 or 3a and the space between any two embossings is the same.

Thus it will be seen that when a front sheet I and a back sheet Ia are assembled with the inlet 4 and outlet 4a diagonally opposite there will be formed a continuous zig-Zag passage for cooling fluid from inlet 4 to outlet lia. After placing the sheets together they are seam welded (indicated by the black dots w in the drawings) along the marginal portions and between the rows of embossings.

When embodied in shelving, the parallel rows of embossings 2X, 23X (Fig. 3) or 2W, Elay (Fig.` 4) preferably run lengthwise of the sheets instead of 4crosswise of the same as in Fig. l.

Instead of having the inlet and outlet opening normal to the plane of the plate, they may be formed to open edgewise of the same as shown at IIay and IIY in Figs. 4 and 5.

Plates I may be secured together as indicated in Fig. 7 to form the four sides of a can by bending the ends, as at I, and welding them together.

Pipes Id connect the outlet of one plate to the inlet of the next adjacent plate of the sides (see Figs. 7 and 8).

After assembling the four side plates I--Ia a top flange Ib and a bottom plate Ie are welded to the plates I--Iag as indicated in Fig. 8, to complete the can. The can is then placed in a suitably insulated box in a manner well known and forming no part of my present invention.

All embossings being of the same length (except the inlet and outlet ones) and being equally spaced apart as above described, the front and back sheets of metal can be embossed by a single set of dies such as that which comprises the subject matter of my co-pending application led July 19, 1946, Serial Number 684,967.

From the foregoing description taken in connection with the accompanying drawings it is thought that the construction, uses and advantages of the invention will be clear to those skilled in the art.

What I claim is:

A cooling-coil-plate formed of two metal sheets placed in face to face contact and having outwardly extended parallel rows of elongated embossments, the embossments of one sheet being staggered with respect to and overlapping the embossments of the other sheet to provide continuous-flow passages from first one inner face of the sheet and then to the inner face of the other sheet, each sheet having a row of elongated embossments along one side for connecting alternate rows of the rst mentioned embossments at opposite sides of the plate thereby forming a continuous-fluid passage from an entrance adjacent one corner of the plate to an exit adjacent the diagonally opposite cornen` of the same said passage zig-zagging from one side of the plate to the opposite side and from front face to back face of the plate.
