COOLING UNIT FOR REFRIGERATING SYSTEMS Filed May 15, 1929 loops Patented Aug. 19, 1930 "UNITED STATES PATENT OFFICE FRANKLIN G. SLAGEL, OF BUFFALO, NEW YORK, ASSIGNOR TO FEDDERS MANUFACTUR- ING COMPANY, INC., OF BUFFALO, NEW YORK, A CORPORATION OF NEW YORK COOLING UNIT FOR REFRIGERATING- SYSTEMS Application filed May 13,
This invention relates to a cooling .unit for use in household refrigerating systems and has the object to provide a unit for this purpose which is very compact and provides greater cooling capacity for the amount of space occupied and metal employed.
. In the accompanying drawings:
Fig. 1 is a side elevation of a refrigerator cooling unit embodying my improvements.
Fig. 2 is a cross section thereof taken on line 2-2, Fig. 1. p
' F ig. 3 is a bottom plan view of the same.
In the following description similar characters of reference indicate like parts in the several figures of the drawings.
The numeral 10 represents the vaporizing tank or chamber which may be of any suitable form but preferably that of a cylinder having its axis arranged horizontally and provided at its front end with a lower inlet 11 for the liquid refrigerant and an upper outlet 12 for the vaporized refrigerant.
Below the vaporizing tank is arranged the cooling chamber 13 which is preferably of rectangular form in cross section and provided at its front end with a door 14 which aflords access to the interior of the cooling chamber for the introduction and removal of ice trays 15 and anything else that requires cooling.
Extending downwardly from the under side of the vaporizing tank and along opposite longitudinal sides of the cooling chamber are two longitudinal rows of vaporizing tubes 16, 17 which communicate at their upper ends with the interior of the vaporizing tank so that the refrigerant is capable of passing back and forth in these tubes and the vaporizing tank.
The tubes on each side of the cooling chamber are connected at their lower ends in pairs so that each pair forms a loop'and some of these loops terminate at the side of the cooling chamber while at least one of the rojects transversely inward underneath t e bottom of the cooling chamber. As shown in the drawings two airs of straight tubes 16 are provided and t 16 tubes of each of these pairs are connected by a vertical bow or turn 18 so that the respective pair of tubes 1929. Serial No. 362,637.
and the turn associated with the same form. a loop which terminates at its closed lower end at the side of the cooling chamber and communicates at its upper end with said vaporizing tank.
Each of the tubes 17 has a vertical upper part arranged between a pair of straight tubes 16 and the lower ends of the tubes 17 of adjacent pairs of tubes 16 have their lower parts 19 turned horizontally inward so that the same are of angular form and connected by a horizontal turn or bow 20, thereby'forming a loop. These lower parts 19 and the turn 20 of each angular tubular loop are arranged below one-half of the cooling chamber, as shown in Figs. 2 and 3.
The upright parts of the tubes are connected on their inner sides with the cooling chamber and the opposing parts of the turns 20 are also connected with each other, which connections are preferably effected by solderin or brazing thereby producing a very rigi and durable structure.
By this organization of tubing it is possible to employ a smaller amount of large size tubing instead of a larger amount of small size tubing, thereby reducing the number of tube joints on the vaporizing tank and reducing the possibility of leakage accordingly.
I claim as my invention:
1. A cooling unit comprisin a vaporizing tank, two longitudinal rows 0 tubes extending downwardly from the underside of the tank, each row of tubes having pairs of straight tubes which are connected at their lower ends by vertical turns so that each pair of straight tubes and the vertical turn connecting the same form a loop, and each row of tubes also containing two angular tubes each of which has a vertical part arranged between one of said pairs of straight tubes and an inwardly extending horizontal part, the inner ends of the horizontal parts of adjacent angular tubes being connected by a turn.
2. A cooling unit comprising a vaporizing tank, two longitudinal rows of tubes extending downwardly from the underside of the tank, each row of tubes having pairs of straight tubes which are connected at their lower ends by vertical turns so that each pair 100 of straight tubes and the vertical turn connecting the same form a loop, and each row of tubes also containing two angular tubes, each of which has a vertical part arranged between one of said pairs of straight tubes and an inwardly extending horizontal part. the inner ends of the horizontal parts of adjacent angular tubes being connected by a turn and a cooling chamber arranged below said vaporizing tank and between the upright parts of said rows of tubes and above the horizontal parts and the turns of said angular tubes.
3. A cooling unit comprisin a vaporizing tank, two longitudinal rows of tubes extending downwardly from the underside of the tank, each row of tubes having pairs of straight tubes which are connected at their lower ends by vertical turns so that each pair of straight tubes and the vertical turn connecting the same form a loop, and each row of I tubes also containing two angular tubes, each of which has a vertical part arranged between one of said pairs of straight tubes and an inwardly extending horizontal part, the inner ends of the horizontal parts of adjacent angular tubes being connected by a turn and a cooling chamber arranged below said vaporizing tank and between the upright parts of said rows of tubes and above the horizontal arts and the turns of said angular tubes, t e upright parts of said tubes being connected with the sides of said cooling chamber and the turns of said angular tubes being connected with each other.
In testimony'whereof I hereby afiix my signature.
FRANKLIN G. SLAGEL.
