Patented Apr. 28, 1931 UNITED STATES PATENT, OFFICE EDWARD H. SEELERT, F MINNEAPOLIS, MINNESOTA, ASSIGNOR T0 MCQUAY RADI- ATOB CORPORATION, OF MINNEAPOLIS, MINNESOTA, A CORPORATION OF DELAWARE END TANK FOR HEAT-EXCHANGE UNITS Application filed December 16, 1929. Serial No. 414,895.
My present invention relates to a heat exchange unit and has for its -primary ob ect the provision of an extremely simple and highly efficient end tank for a radiator core having horizontal tubes.
Generally stated, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.
1 In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.
Referring to the drawings:
Fig. 1 is a view partly in front elevation and artly in longitudinal vertical section of a eat exchange unit in which the invention is embodied;
Fig. 2 is a perspective view of one of the end tanks;
Fig. 3 is a view principally in horizontal section taken on the line 33 of Fig. 1, on an enlarged scale;
Fig. 4 is a transverse vertical section taken on the line 4-4 of Fig. 3; and as Fig. 5 is a longitudinal vertical section taken on the line 5-5 of Fig. 4. V The heat exchange unit illustrated comprises a pair of spaced cast metal end tanks 6 having open backs and a radiator core therebetween. Said radiator core comprises vertically and horizontally spaced horizontal flat tubes 7, headers 8 on the ends of said tubes and fins 9 on the tubes 7 between said headers. The tubes 7 have communication :5 with the end tanks 6 and said headers close the open backs of the tanks 6 and are secured thereto by steam and water tight joints. This heat exchange unit further includes a pair of side plates 9' for the radiator core and which plates are rigidly secured at their ends to the end tanks 6, as indicated at 6 and have on their longitudinal edges inturned flanges 9' ers 8 and fins 9. x In the bottom of each end tank 6 is a which overlie the headsump 10 into which all of the tubes 7 drain and in the face of said tank is a 'bossed opening 11 through which said sump drains. The openings 11 are tapped and short horizontal pipes 12 are secured therein. Couplings 13, one of which is a valve casing, connect the pipes 12 to the upper ends of vertical intake and return pipes 14 and 15, respectively.
sheet metal cabinet for the radiator core is indicated as an entirety by the numeral 16 and may be supported in any suitable manner. I m
The connections for the radiator core, as illustrated, are for a hot water heating system and for certain other heating systems such as steam wherein only one pipe will be used, and in which case the opening 11, in one of the end tanks 11, will be plugged. All of the tubes 11 drain into the sumps 10 and when only one pipe leads to the radiator core, said core will be supported so that its tubes drain into the sump 10 in the end tank to which the supply pipe leads.
As shown, the radiator is supported entirely from the pipes 14 and 15 and when legs are used for supporting a radiator core they will be secured in apertured ears -17 integrally formed with the end tanks 6, see Fi s. 2 and 3.
baflie 18 is mounted in the intake end tank 6 and is in the form of an apertured plate secured within said tank just forward of the respective header 9 extends the full height of said tank and is ll-shaped in horizontal section. The purpose 0 this bafiie 18 is to more evenly distribute the heating medium from the intake end tank 6 to the several vertically and horizontally spaced rows of tubes 7 and thereby increase the efiiciency of the radiator core.
As is well-known, each section of a standard cast iron radiator has a length, in reference to the radiator, of two and one-half inches and in my present invention each I end tank 7 has a corresponding length and each end tank.
the tubes between the two end tanks have a length that is a multiple of the length of By thus standardizing my radiator core and end tanks, the same may be readily substituted for a cast iron radiator, mounted in the same space occupied thereby and without changing the intake or outlet pipes.
By providing the end tanks 6 with sumps 10 the radiator core may be mounted in a true horizontal position and hence not necessary to incline the same for the purpose of drainage.
Lines Y indicate the sections of an ordinary cast iron radiator.
Without the use of the bafile 18 in the intake end of a steam radiator the steam, when first turned on, will-rush into the core of the radiator with considerable velocity and fill the center tubes, which are directly opposite the steam inlet, before entering the rest of the tubes. Under such a condition the heat of the steam will cause the center tubes to expand first thereby, setting up mechanical strains between the tubes and headers. The object of this bafiie 18 is to break up such a rush of steam and evenly distribute it throughout the core so that all of the tubes receive steam at ap roximately the same time, resulting in unif drm expansion of the core without subjecting it to mechanical strains. Said baffle also prevents a sudden rush of steam into the radiator which would carry any accumulation of water due to condensation through a few of the tubes at a high rate of speed causing a gurgling noise in the core.
What I. claim is:
1. A heat exchange unit comprising an end tank, a radiator core having horizontal tubes in communication with the end tank,
said tank having a sump into which the tubes drain and a horizontal outlet opening through which the sump drains, and a bafiie in the end tank' arranged to drain into the sump.
- 2. A heat exchange unit comprising two spaced end tanks, a radiator core between the end tanks and having horizontal tubes in communication therewith, each end tank having a sump into which the tubes drain, and a horizontal outlet opening through which the sump drains, and a baflle in the receiving end tank arranged to drain into the respective sump.
3. A heat exchange unit comprising an end'tank having an intake opening, a radiator core having a row of tubes in communication with the end tank, and a bafiie in the end tank between the intake opening and tubes, said bafile being in the form of an apertured plate that is V-shaped in the plane ofsaid row of tubes with its apex toward the intake opening and forms a transverse partition in the end tank.
4. A heatexchange unit comprising an end tank having an intake opening, a radiator core having horizontally and vertically spaced horizontal tubes in communication with the end tank, and a bafiie in the end tank between the intake opening and tubes, said battle being in the form of an apertured plate that is V-shaped in horizontal section andkforms a transverse partition in the end tan In testimony whereof I afiix my signature.
