Application died March 1 To all whom may concern:

Be it known that WALTER Iii. Dunn acitizen of the United States and a resident or" lii illrinsbur in the county of Allegheny and State of Z'ennsylvania, have invented a new and useful improvement in Transformer Radiators, of which the following, is a specification.

invention relates to heat-dissipating devices and it has peculiar relation to apparatus oi the above designated character that is particularly adapted for use in connection with electrical or other apparatus adapted to be immersed within a cooling fluid. More specifically, my invention relates to means for cooling the oil or other fluid used in transformers and to the construction oi such means One object of my invention is to provide aradiator of novel type having a relatively radiating; area, as compared with the quantity oi cooling therein.

Another obiect my invention is f m radiators shall be light in weig and inexpensive in manufacture and we designed to withstand considerable without deformation. is ie speaking n invention comprises constructing theside walls, the top and bottom members and the end walls of separate members which are welded together after being assembled.

llereto'iore it has been customary to con: struct radiators of spaced tanks or headers and a plurality of spaced tubes disposed intermediate, and communicating with said headers. lihe objection to such. structures is that dead air spaces of substantially pyramidal shape are forme of which the inner surfaces of the headers constitute the bases.

According to my invention, my radiator comprises a vertically extending central chamber having a plurality of ofi'set chambers radiating therefrom. The offset portions are formed by the side walls which consists of a plurality of segments of substantially ti-shape joined together in side by-side relation. Each of the top and the bottom enclosing members of the central vertically-extending chamber is of substantially Ushape. The ends of the radiator are closed by separate end members welded to the ends Z, 1921. Serial N0. 452,35?

of the side walls and to the ends of the top and bottom members.

In the accompanying drawings, Figure l is a plan =view of a radiator constructed in accordance with my invention.

Fig. 2 is a'view, partially in end elevation and partially in section, 0% the structure shown in Fig. l, the sectional portion oi this figure being taken along; the line HH of Fig. 1.

Fig 3 iso perspective view of certain of the members embodied in a radiator constructed in accordance with my invention. According to my invention a radiator comprises a top member 4i and a bottom memher 5 joined together at the sides by walls 6 and 'Z and at the ends by end members 8 and 9. Each of the members 4- and 5 consists of a pressed metal part of substantially U- shape which constitutes the top and the bottom, respectively, of a vertically-extending fluid chamber 10.

Each of the side walls 6 and 7 comprises a plurality of pressedmetal members 11 of substantially U-shape,.as best shown in Fig. 8. F or the sake of clearness, but two such members are shown on each side. Each of the members 11 consists of a base portion 12 and two integral side portions 13 of substantially dish-shape. The base portion 12 is welded at the-top and at the bottom to the members 42 and 5, respectively. The edge of each of the side portions 18 is adapted to engage the edge of the side portion oi the next adjacent member 11. .This forms a flat metallic envelope having an open side which is in communication with the central chamber 10.

Each of the side members 13 is provided with extruded portions 1% to engagesimilar portions extending from the other integral portions 13 which constitutes one wall of the next adjacent fluid chamber. Distortion of the walls by the pressure of the fluid within the members 11 is thereby prevented. Each-of the twocoacting portions 13 of adjacent units 11, which cooperate to form a radiating chamber is provided with an outwardly projecting flange 15 which is welded to a similar coacting flange 15 oi the next adjacent portion 13.

Each of the end members 8 and 9 is of -with a flange 17 of similar contour to the proper operative positions.

flange 18 of the member 16, to which it is welded. A plurality of extruded vertical ribs 19 serve to reinforce the end members 8 and 9. A plurality of tie-bolts 20, extending through the end members 8 and 9 and the vertical chamber 10, serves to support the entire radiator and to add to its rigidity and strength. Bracing members 21 are disposed at the ends of the bolts 20 to engage the end members 8 and 9. Each of the end members 8 and 9 is provided with oflset integral projections 22 at the top and bottom thereof which serve as closures for the ends of the top and bottom members 4 and 5, respectively, and are provided with flanges 23 which are welded to said members.

The radiator may, if desired, be constructed b first assembling" a series of units 11 in si e-by-side relation and welding together their adjacent flan es 15. The end members 8 and 9 may then e welded to the end sections 16 of the assembled units, and the tiebolts 20 and braces 21 be disposed in their The top and the bottom members 4 and 5, respectively, may then be placed in position, being welded tothe ends of the base portions 12 of the side members 11 and to the flanges 23 of the offset portions 22 of the end members 8 and 9. I

The ofiset portions 22 of the member 8 are provided with apertures 24 by means of which communication is established with a tank or other container, not shown. The pipes associated with the apertures 2 L also serve as supports for the radiator.

From the foregoing description, it will be apparent that I have produced a radiatorof novel-type, that is light in weight, simple and inexpensive in manufacture, and durable in operation. Also, -it is apparent that, in a structure manufactured in accordance with my invention, a free circulation of air in a vertical direction between the various sections is facilitated by reason of the straight walls thereof.

I claim as my invention:

2. A radiator'comprising a main chamber enclosed by spaced top and bottom membersand two parallel-side walls disposed intermediate said members and attached thereto, said side walls severally comprising a plurality of separate members of substantially -shape disposed in side-by-side'relation the adjacent edges of which are welded together to form auxiliary chambers closed on three sides and communicating with said main chambers-T Y 3. A radiator comprising two parallel side walls severally composed of members of substantially U-shape disposed in sideby-side relation, the outer ed es of said members being bent outward y to form flanges, the flanges of adjacent members being welded together to form an envelope closed on three sides, and top and bottom members for connecting the ends of said first members in spaced relation to form a main chamber communicating with the open side of said envelopes. r
