3,008,692 RADIATOR CONSTRUCTION George Gerard, 1698 East Drive, West Point Pleasant, NJ.

Filed Oct. 14, 1959, Ser. No. 846,369 6 Claims. (Cl. 257-136) The present invention relates to a radiator construction and it particularly relates to a radiator construction for hot liquid systems.

It is among the objects of the present invention to provide a simple, compact radiator system particularly designed for achieving maximum heat utilization with circulating hot liquids systems.

further objects and advantages will appear in the more detailed description set forth below, it being understood, however, that this more detailed description is given by way of illustration and explanation only and not by way of limitation, since various changes therein may be made by those skilled in the art without departing from the scope and spirit of the present invention. In accomplishing the above objects it has been found most satisfactory, according to one embodiment of the present invention, to provide a fin construction in which the pipes extending through a series of parallel, closely spaced fins will be so arranged as to be conveniently located in recesses within the wall of a room or along the side of the wall without undue or uneconornical space consumption.

It has been found, according to the present invention, that, with one header outlet and return,'connections may be-readily made with assurance of maximum utilization and circulation of the hot liquid in its passage from the furnace and back to the furnace.

Desirably a series of parallel horizontal pipes are positinned-in a wall recess which may be insulated from the rear so that full heat reflection will occur forwardly into the room space.

The units consisting of a plurality of fins, the spaces between which are closed by in-turned flanges, may be positioned with their front edges in or along the plane of the wall. The inlet and outlet connection to each radiator series is achieved by having pipes in the main header facing the direction of flow and away from the direction of flow so as to create a forced flow through the radiator sections themselves. I

With the foregoing and other objects in view, the invention consists of the novel construction, combination "and'arrangement of parts as hereinafter more specifically described, and'illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modijfications can be res'ortedto which fall within the scope of the claims hereunto appended.

In the drawings wherein like reference characters def noted corresponding parts throughout the several views:

. FIG. 1 is a side diagrammatic elevational view illustrating the connection between the radiators and the main headers.

' "FIG. 2 is a transverse sectional view indicating how the radiator unit may be' inserted in the wall of a room or other enclosure.

Refering to FIG. 1, there is shown the main flow pipe r 2 A carrying the heated liquid which may be of light or medium bodied oil, with the branch connections B as an inlet and C asan outlet to the various radiator sections C, D E and F which are inserted in the wall structure G.

Each radiator section C, D, E and P has alhorizontal main pipe or tube H with a plurality of radiating fins I and with the inlet connection K and the outlet connection L respectively. l g The units are held in position by means of the spring clips or resilient members M which extend inwardly from the wall sections N. The radiator unit has a back casing P and a front closureframe Q.

Referring to the main flow pipe A, which may be positioned between the walls or between the ceiling and floor, the hot oil is caused to flow in the direction 10 under pump pressure from a furnace.

At the inlet connection B the end of the tube, as

indicated at 11, faces the direction of the oil flow and has a slight enlarged bell-shaped mouth 12, with the result that oil will be forced at 13 into the curved inlet neck B. At the other side there will be an end portion 14 extending in the direction of flow and. the hot liquid will be drawn out, as indicated at 15, through the curved outlet neck section C. Both units B and C are joined into the pipe A by the strong connections 16 and 17.

The piping B connects to the end header K, which extends through the end portions 18 of the horizontal tubes H.

There are flow connections as indicated at 19 adjacent the top of the pipe H. Similar connections are provided at the outlet side L, which also extends through the ends 20 of the headers H. Here, too, the openings 21 are positioned at the top. V

The fins I, which may be closely spaced and parallel to each other, are mounted upon each tube H and may be soldered thereto at their central portions. The spring clipsv M, which are bolted, riveted or screwed at 22 at their lower ends 23, have upper bifurcated sections '24 which fit on to and hold the pipe sections H in position.

Each tube H may be provided with the locator members N atthe ends thereof. As shown in FIG. 2, there are four horizontal tubing sections, each having upper circular openings eccentrically disposed, as indicated at 19 in FIG. 2. V The fins I are spaced apart by the spaces 35, and, if desired, their front ends maybe flanged in one direction so as to close the spaces 36 between them and give maximum radiating surface. I

The open portions, as indicated at 37 andj38, permit the air to pass in,'as indicated at 39, and pass out, as indicated at 40, to give maximum radiating effect.

The frame Q may carry anornamental grill and the back plate or casing P may be made of sheet steel or of other metal material, preferably with an interiorly polished face, as indicated at 41.

Desirably the fin length will terminate inside of the headers K and L, with the ends of the pipe projecting adjacent to but not touching the wall sections N so as to leave space for expansion. 1

The entire unit is very compact and the varying number of sections may be employed from one horizontal pipe'H tofouror more horizontal pipes H.

The fins should extend the full width of the recess, as indicated at P in the wall, and they may be made or]? square or aluminum sheet spaced one inch apart and 2% inches square.

The piping H may be copper piping outside diameter, with wall thickness and the openings 19 may be 1 in one preferred construction.

The upper ends of the vertical members K and L are plugged, as also are the ends of the horizontal tubes H.

The inlet and outlet connections, as indicated at B and C, will give a Venturi tube efiectand will assure a forced flow of hot oil or other liquid through the radiators consisting of the horizontal pipes H and the fins I.

The system will be most effective in heat utilization and may be conveniently installed, particularly with hot oil systems.

As many changes could be made in the above radiator construction, and many widely difierent embodiments of this invention could be made without departure from the scope of the claims, it is intended that all matter contained in the above description shall be interpreted as illustrative and not in a limiting sense.
