Allyne, Cleveland, Ohio, assignor to Allyne Laboratories, Inc., Cleveland, Ohio, a corporation of Ohio Application October 19, 1935, Serial No. 45,813 5 Claims. (Cl. 62-95) This invention relates to brine tanks and more particularly to heat exchange tanks for use in connection with household refrigerating appara tus of either the absorption or compression types. An object of the invention is to construct a brine tank of great strength fabricated from sheet metal stampings. A further object of the present invention is to construct a sheet metal brine tank which will 10 always be in e?icient thermal contact with the evaporator tubes of therefrigerating ‘apparatus and which may be readily installed or removed as a unit from the evaporator tubes. A still further object is to construct a brine 15 tank unit made up of a liner and two identical sheet metal sides which are easily ?tted to and welded around the liner to form a complete only strengthens the unit but also gives a large air cooling area to the tank. The front and rear edges of the sections 6 and ‘I are sloped inwardly at 9 and I0 and welded to the outer edges 5' of the liner l. The flared top and bottom edges II and I2 of the sections 6 and 'l are welded together to form a complete brine tank having a large open inner space for the reception of the ice trays. A threaded nipple l3, forming ?lling nozzle, for 10 interior space of the brine tank is fastened in a sloping beveled front edge 9 of one of the main side sections, while offset hangers M are welded to the rear sloping sections Ill to assist in sup porting the tank unit in the refrigerating box. 16‘ Notched plates 15 may be brazed or otherwise attached to the corrugated side walls for the pur pose of holding the ends of horizontal food trays. brine tank. ' To give a pleasing appearance to the unit, a face Referring to the drawings: Figure l is a front elevation of the complete ‘plate l6 may be amxed to the front of the tank. 20 Conventional ice cube trays 88 may be mounted brine tank unit.

The ?ared-out meeting edges are section, of the front and rear portions of the up per part of the brine tank taken on line 5-5 welded to complete the inner section of the tank. The outer spaced top, bottom and side walls of of Fig. 3. the brine tank are also formed by a mere metal Figure 6 is an opened-up assembly view show stamping operation, and, as above described, the ing the manner in which the parts are ?tted to n gether. Referring more speci?cally to the drawings: Numeral l illustrates a rectangular sheet metal casing formed of a single piece of bent metal welded at 2 along its upper central abutting edges. The liner l is provided with oppositely disposed pairs of vertically spaced pressed-in sections 3, leaving longitudinal grooves 4 between each pair of pressed-in sections 3. It will be observed from Figure 4 of the drawings that the outer ends of the pressed-in sections 3 are beveled as indicated by numeral 5 and terminate in a ?at edge 5'. 45 Thus it will be seen that the liner 1 constitutes the inner surface of the brine tank which has a large unobstructed central area. The outer spaced side walls and top and bot tom of the tank are made from two identical U two halves ?tted around the liner are identical and prepared from the same dies so that there are no rights or lefts but may be used interchange 35 ably. In assembly, the two outer stampings are ?tted over the liner and welded at their top and bottom meeting lines and also to the outer edges of the liner. _ The corrugated top, bottom and sides give 40 strength to the unit and also provide channels for accelerating the circulation of chilled air around the tank and consequently through the food compartment of the refrigerator. As before stated, the present invention is suit— able for use with all types of household refrig eration apparatus and functions equally well with an absorption cycle system as with a motor compresslon out?t. In either type, the evapora one-half of the top and bottom of the tank and, tion tubes or coils are frictionally ?tted into the 50 grooves formed in the side walls of the liner and snugly held thereby to e?ect an e?icient heat ex as seen in Figures 2 and 4, the top and bottom and side walls are corrugated as indicated by cube trays. shaped sheet metal stampings 6 and 1. Each of these stampings consists of a side wall and 55 numeral 8. This corrugated‘ construction not change to the liquid in the tank and to the ice. While not shown, it will be understood by those 65 2 2,114,204 skilled in the art that the lique?ed refrigerant in the system is ?owed through the tubes i‘! to chill the brine or other heat exchange ?uid retained in the hollow Walled tank. The tubes iii are con nected to the evaporator or liquid gas receiver and may be of any suitable construction provided they are in solid contact with the horizontal grooves ii to thus effect proper heat exchange with the side walls 01 the liner. 10 What I claim is: 1. A brine tank including a holiow inner liner having pairs 01’ vertically spaced longitudinal grooves integrally formed in the side walls there» of, adapted to frictionally engage and be sup 15 ported on the evaporator tubes of a refrigerat ing system, and a. spaced casing surrounding the top, bottom and sides or" said liner ffornnng a ?uid tight container. 2. A cooling unit for refrigerating apparatus including a hollow rectangular, ?uid-tight, dou ble walled casing open at both ends thereof, a plurality of pairs of horizontal, vertically spaced grooves formed in the inner side walls of the said casing and extending from end to end 25 thereof, the said grooves being adapted to re» tain a plurality of pipes in. circuit with the evaporator of the refrigerator system to there“ by support the said cooling unit. 3. A brine tank for refrigerators consisting of 30 a hollow rectangular inner casing having pressed-out horizontal grooves in its inner side walls for the reception of conduits carrying iiq~ uid refrigerant, the said inner casing comprising a single sheet of bent metal, and a spaced outer casing enclosing said inner _ casing comprising two identical hollow sheet metal stampinge oi’ substantial U—shape fitted on either side or said inner casing and welded thereto. 4. A brine tank for refrigerators including an inner liner formed from a single sheet oi’ metal bent to form a hollow rectangular casing with its meeting edges welded together, integral, hor izontal, parallel, spaced apart grooves i'ormed in 10 the opposite vertical side walls of said inner liner, a spaced outer casing surrounding the four sides of said inner liner and welded thereto adjacent ' the open ends of the said inner liner, the outer casing being fabricated from two identical sheet metal sections welded together at their abutting edges, . 5. A brine tank for household refrigerators including an inner liner in the form of an open ended sheet metal rectangle, and having grooves formed in its inner walls for the reception of 20 refrigerating conduits, an outer casing surround ing the said inner liner at the top, bottom~ and two sides thereof, said outer casing comprising two identical sheet metal sections of substantial 25 u shape both in con?guration and in cross sec-' tion. each outer section of said casing forming a side wall and one half of the top and the bot tom. for said liner, the abutting edges of the two sections of said casing being'welded to each 30 other and the outer edges thereof being welded to the inner liner adjacent its open ends.
