Abstract

A radiator for water-carried heat includes a hollow radiator body (10) having end-edges and side-edges (11; 12, 13). The radiator body has a flat side which is provided adjacent one of the end-edges with two openings (14, 15) via which the interior of the radiator body (10) communicates with the interior of two connector heads (16, 18) which are carried by the radiator body and which communicate with one another via a connecting pipe (21) that extends therebetween. Each connector head (16, 18) has a first connector stub (19) which extends outwardly in relation to the adjacent end-edge (11), and two second connector stubs (20, 22, 23) which extend outwardly in relation to the adjacent side edge (12, 13). The first and the second connector stubs (19, 20, 22, 23) can be closed selectively or connected selectively to hot water inlet and return lines. Communication between on the one hand each pipe end-part (22, 23) and on the other hand the first connector stub (19) of the connector head (16, 18) associated with the pipe end-part in question and the opening (14, 15) leading to the interior of the radiator body (10) can be selectively broken.

Description

A Radiator for Water-Carried Heat

The present invention relates to a radiator for water- carried heat according to the preamble of Claim 1.

A radiator of this- ind is already known from -* SE-B-467 069. This known radiator, however, is intended and constructed exclusively for connection to a pair of upwardly extending water-supply and water-exhaust pipes for carrying respectively hot water and cold water which has been cooled in the radiator, so-called floor-connected radiators. The first or upper connector head has a connector stub which extends outwardly in relation to the adjacent radiator end-edge and is intended to receive a valve, for instance a thermostat valve, for setting or adjusting the flow of water through the upper connector head and therewith through the radiator. The second or bottom connector head is connected to the upwardly-_extending pair of pipes by means of a separate coupling piece which com- prises two channels, of which a first channel can be connected to the connector stub of the bottom connector head, while a second channel arranged within the first channel and extending concentrically therewith can be connected to the end of a connecting pipe that pro- jects into the bottom connector head. Each of the oppo¬ site ends of said channels can be connected selectively to a respective pipe in the upwardly extending pair of pipes. When the radiator comprises two radiator bodies, the radiator includes connector heads which are common to both radiator bodies and which include connecting pipes which are -hidden between the radiator bodies. The radiator can therewith be turned about a vertical axis, so as to enable the radiator to be connected either from the left or from the right, which is advantageous from the point of view that fewer types of radiator need be manufactured and held in store. A radiator which comprises two relatively flat radiator bodies and which is intended for both floor and side connection and also for both left and right connection is known from DE-U-90 365.

In this case, the radiator bodies are mutually connected in all four corner regions of the radiator bodies via connector heads. The radiator heads located at one end of the radiator have no immediate communication with one another and are provided with side-connection con¬ nector stubs which extend outwardly in relation to the adjacent radiator edge. The connector heads located at the other end of the radiator communicate with one another via a connecting pipe, wherein the upper connec- tor head has a connector stub in which a valve, for instance a thermostat valve is mounted, whereas the bottom connector head includes connector stubs for connecting the radiator to a floor connection. This latter construction thus reduces the number of necessary types of radiator still further, although at the cost of a more complicated construction.

The object of the present invention is to provide a radiator which can be connected to the pipe network from the side of the radiator and from the floor and which is suitable for both right and left connection, and which is of simpler construction than earlier known radiators and therewith less expensive.

To this end, there is proposed a radiator of the kind defined in the introduction which also includes the features set forth in the characterizing clause of Claim 1. Such a radiator affords the advantages intended in the form of a simplified construction and improved use possibilities, not only with twin radiators, i.e. radia¬ tors which include two radiator bodies, but also with a radiator which has only one radiator body, due to the fact that the side edges of the radiator can form selec¬ tively the bottom edge or the top edge of the installed radiator.

Other characteristic features of the inventive radiator and advantages afforded thereby will be evident from the depending Claims and from the following description of an exemplifying embodiment of an inventive radiator illustrated in the accompanying drawings, from which different methods of use will be made evident.

Figure 1 is a vertical sectional view of an inventive radiator? Figure 2 is a sectional view of one end-part of the radiator, taken on the line II-II in Figure 1; Figure 3 is a section view of one end-part of the radia¬ tor, taken on the line III-III in Figure 1; Figures 4-7 are section views corresponding to the view of Figure 3 and illustrating different methods of use; and

Figures 8 and 9 are respective section views ccrespond- ing to Figure 3 and illustrating a slightly modified form of the inventive radiator and also illustrating different methods of use.

The radiator illustrated in Figures 1-3 is comprised of two relatively flat hollow radiator bodies 10 which are positioned centrally opposite one another and which have end-edges, of which only one, 11, is shown, which extend vertically in the normal use position of the radiator, and horizontal side edges 12, 13. The radiator bodies 10 are provided on their mutually facing sides, adjacent one end-edge 11, with two vertically spaced first and second openings 14 and 15, through which hot water is able to flow to and from the radiator bodies. The reference numeral 16 identifies generally a hollow first connector head which is carried rigidly by the radiator bodies 10. More specifically, the connector head 16 includes two at least generally horizontal tubular members 17 which extend in mutually opposite directions and the orifice defining walls of which are firmly welded to a respective radiator body 10 around a respec¬ tive opening 14. A correspondingly formed second connec¬ tor head 18 also includes two tubular members 17 which extend in mutually opposite directions and each of which is welded to a respective radiator body 10 around a respective opening 15. Each connector head 16, 18 also includes a first connector stub 19, which extends out¬ wardly in relation to the adjacent end-edge 11 of the radiator body, and a second connector stub 20 which extends outwardly in relation to the adjacent side-edge 12 or 13 of said radiator body. All of the connector stubs 19, 20 are provided with a preferably similar internal screw thread, suitably R "• The connector stubs 19, 20 may also be provided with preferably similar external screw threads, e.g. M28xl.5.

The connector heads 16 and 18 communicate with one another via a connecting pipe 21 which extends between said heads. The connecting pipe 21 has end-parts 22, 23 which extend slightly into a respective connector head, with the outer surfaces of said end parts spaced from the inner surface of^" the connector head. The pipe ends 22, 23 are advantageously coaxial with the connector stubs 20, as shown. These end-parts 22, 23 form similar connector stubs, so that each connector head 16, 18 will present two connector stubs 20, 22 or 20, 23 which extend outwardly in relation to the adjacent side-edge 12 or 13. The connector heads 16, 18 will preferably have a first casing part 24, from which the connector stub 19 extends in one direction, and a second, essentially tubular casing part 25 which extends in the opposite direction coaxially with the connector stub 19. In turn, the casing part 25 opens into a third, essen¬ tially tubular casing part 26 which embraces the end- part 22 or 23 of a connecting pipe and in which the connector stub 20 is formed coaxially with the end-part 22 or 23 of said pipe. The casing part 25 is provided with a fitting 27, preferably a screw-threaded fitting, which extends coaxially with and can be reached through the connector stub 19 and accommodate a closure plug 28 (Figures 4-5), a thermostat seat 29 (Figure 7), or alternatively a thermostat valve 30 (Figure 6). This configuration of the connector stubs 19, 20 enables the stubs to be closed selectively by means of a closure cap 31 (Figures 4-7) or plugs 32 (Figures 5-7), or enables the connector stubs to be connected to hot water inlet and return lines (not shown). In actual fact, the illus¬ trated embodiment is such as to enable the radiator to be used with all radiator-connection applications at present available on the market, irrespective of whether the radiator comprises one or two radiator bodies 10.

The radiator illustrated in Figure 4 is in a side-con¬ nection state, wherein hot water will enter through one connector stub 19 and the opening 14, while used water will depart through the opening 15 and the other connec¬ tor stub 19. Screwed to the fitting 27 of the bottom connector head 18 is a closure plug 28, while the con¬ nector stubs 20 are closed by means of a closure cap 31, therewith forcing the water to pass through the radiator bodies 10.

The radiator illustrated in Figure 5 is in a convention¬ al floor-connection state, wherein hot water is intro- duced through the bottom connector stub 20 and is caused to flow up through the connecting pipe 21 and into the radiator body 10 through the opening 14. The connector stub 19 of the top connector head 16 is provided with a closure plug 32, whereas the connector stub 20 of said connector head is provided with a closure cap 31. Final- ly, a closure plug 28 is screwed onto the fitting 27 of_ the bottom connector head, thereby forcing the water to flow out through the opening 15 and an elbow pipe 33 screwed to the bottom connector stub 19.

The radiator illustrated in Figure 6 can be coupled to a floor connection via a connector piece (not shown) of the kind which has mutually concentrical supply and return lines in the region intended for connection to the radiator, for instance a connector piece of the kind described and illustrated in SE-B-467 069. The hot water will therewith enter through the bottom end of the connecting pipe 21 and flow upwards into the radiator bottom 10 through a thermostat valve 30 and the top opening 14, partially hidden by the valve 30. The ther- mostat valve 30 is comprised of a thermostat insert, for instance a "DANFOSS" insert, screwed into the fitting 27 of the connector head 16 and the internally screw- threaded connector stub 19. The connector stub 20 of the connector head 16 is closed by means of a cap 31 and the connector stub 19 of the connector head 18 is closed by means of a closure plug 32, thereby forcing the water to depart through the opening 15 and the space around the bottom end 23 of the connector stub 20 of the connector head 18.

Figure 7 illustrates an arrangement similar to the arrangement shown in Figure 6. The only difference is that another thermostat construction is used (type Heimer, TA, etc) . In this case, the arrangement in- eludes a separate thermostat seat 29 which is screwed into the fitting 27 of the connector head 16, while the remainder of the thermostat insert 34 is screwed into the connector stub 19 of the head 16.

In the case of the radiator illustrated in Figures 8 and 9, each connector head 16, 18 has a first connector stub 19 which extends outwardly in relation to the adjacent end-edge 11 of the radiator body, and two second connec¬ tor stubs 20a, 20b which extend outwardly in .relation to the adjacent side-edge 12 or 13 of the radiator body. All of the connector stubs 19, 20a, 20b are advanta¬ geously provided with a preferably similar internal screw thread, suitable R^". The connector stubs may also be provided with preferably similar external screw threads, e.g. M28xl.5.

The connector heads 16 and 18 communicate with one another via a connecting pipe 21 extending between said heads and having ends 22, 23. Advantageously, each pipe end 22, 23 is generally coaxial with one of the connec- tor^" stubs 20a, 20b, as illustrated. The connector heads 16, 18 include a first casing part 24, from which the connector stubs 19 and 20b extend, and a second, gener¬ ally tubular casing part 25 which extends coaxially with the connector stub 19 in the opposite direction to the first casing part 24 and, in turn, opens into a third casing part 26 which receives the end 22 or 23 of the connecting pipe and in which the connector stub 20a is formed. The casing part 25 carries a fitting 27, prefer¬ ably a screw-threaded fitting, which accommodates a closure plug 28, a thermostat seat 29 or a thermostat valve 30 (Figure 9), said fitting extending coaxially with the connector stub 19 and being accessible through said stub. This configuration of the connector stubs 19, 20a, 20b enables said stubs to be closed selectively by means of, e.g., plugs 32 (Figure 9) or to be connected to the hot water supply and return lines (not shown). In actual fact, the construction of the illustrated radiator is such as to enable the radiator to be used in all radiator-connecting applications at present avail¬ able commercially, irrespective of whether the radiator comprises one or two radiator bodies 10.

Figure 9 illustrates the radiator in a state for conven¬ tional floor connection, wherein hot water is .introduced through the bottom connector stub 20a, and caused to - flow up through the connecting pipe 21 and into the radiator body 10 through the opening 14. The connector stubs 20a, 20b of the top connector head 16 are provided with closure plugs 32, whereas the connector stub 19 of the connector head is provided with a thermostat 30. Finally, there is screwed into the fitting 27 of the bottom connector head a closure plug 28, so that the water is forced to flow out through the opening 15 and the bottom connector stub 20b. A closure plug 32 is screwed into the bottom connector stub 19. When using the radiator for conventional side connection, all connector stubs 20a and 20b and fittings 27 are provided with plugs 32 and 28 respectively, and the connector stubs 19 are used for supplying and discharging hot water.

The invention is not restricted to the aforedescribed and illustrated exemplifying embodiments thereof, but can be realized selectively in any manner that lies within .the scope of the concept of the invention as defined in the following Claims.
