Definitions
- This invention relates to heat radiators and more specifically to so-called low surface temperature heat radiators.
- the surface temperature of standard central heating radiators can often be as high as 80°C. In everyday use this is not normally a problem. However, should a person fall unconscious on to such a radiator, or is unable to move away from it quickly, unpleasant burns can result, even after a relatively few seconds.
- so-called low surface temperature radiators are being used. These consist of a normal central heating radiator encased within an enclosure which ideally also encases any exposed pipework and the radiator valve. By this means the temperature of the enclosure can be restricted, typically, to about 40°C maximum. If thermostatic type radiator valves are required to be used with such low surface temperature radiators, it is usually impracticable to directly fit them to the heat emitter within the outer enclosure. Thus remote adjusting or remote sensing thermostatic valves usually have to be used, with the associated fitting and siting disadvantages which they have.
- a low surface temperature heat radiator comprising a heat emitter encased within an outer enclosure, said heat emitter comprising an adjustable valve for controlling fluid flow through said heat radiator and said enclosure having an adjustable thermostatic radiator valve thermal head mounted on it, coupling means being provided between said valve and said thermal head whereby said radiator valve is operated in dependence upon the temperature and setting of said thermal head.
- said coupling means comprises a pair of bellows elements interconnected by a flexible capillary tube, one of said bellows elements being associated with said thermal head and the other of said bellows elements being associated with said radiator valve, whereby operation of said thermal head causes said one of said bellows elements to be acted on, and corresponding action of said other bellows element causes said radiator valve to be acted on.
- said radiator valve comprises the valve body of a thermostatic radiator valve, in which case said radiator valve may be disposed at one end of said heat emitter, said thermal head being mounted on a corresponding end of said enclosure, or alternatively said radiator valve may be disposed at one end of said heat emitter, said thermal head being mounted on the opposite end of said enclosure.

- LST low surface temperature
- conventional LST radiators have only been usable with remote adjustable or remote sensing type thermostatic radiator valves which are not appropriate for many applications.
- the LST heat radiator 1 of Fig. 1 has been fitted with a thermostatic radiator valve (TRV) extension kit, as shown in Fig. 3, which enables the valve head 5 of a conventional manually adjustable TRV to be mounted directly on the enclosure 2 of the LST radiator 1, the valve body of the TRV being mounted on the heat emitter in the usual way, as will hereinafter be explained.

Abstract
A low surface temperature heat radiator 1 comprises a heat emitter 6 contained within an enclosure 2, the enclosure 2 having mounted on it a thermal head 5 of a thermostatic radiator valve, the valve body 7 of which is connected to the heat emitter 6, an extension unit 8 being provided comprising first and second bellows units 9 and 10 interconnected by a coiled capillary tube 11, for interconnecting the thermal head 5 and the valve body 7 (Fig. 2).
Description
- This invention relates to heat radiators and more specifically to so-called low surface temperature heat radiators.
- The surface temperature of standard central heating radiators can often be as high as 80°C. In everyday use this is not normally a problem. However, should a person fall unconscious on to such a radiator, or is unable to move away from it quickly, unpleasant burns can result, even after a relatively few seconds. In order to overcome this problem so-called low surface temperature radiators are being used. These consist of a normal central heating radiator encased within an enclosure which ideally also encases any exposed pipework and the radiator valve. By this means the temperature of the enclosure can be restricted, typically, to about 40°C maximum. If thermostatic type radiator valves are required to be used with such low surface temperature radiators, it is usually impracticable to directly fit them to the heat emitter within the outer enclosure. Thus remote adjusting or remote sensing thermostatic valves usually have to be used, with the associated fitting and siting disadvantages which they have.
- It is an object of the present invention to provide a low surface temperature heat radiator having an integral thermostatic radiator valve.
- According to the present invention there is provided a low surface temperature heat radiator comprising a heat emitter encased within an outer enclosure, said heat emitter comprising an adjustable valve for controlling fluid flow through said heat radiator and said enclosure having an adjustable thermostatic radiator valve thermal head mounted on it, coupling means being provided between said valve and said thermal head whereby said radiator valve is operated in dependence upon the temperature and setting of said thermal head.
- In a preferred arrangement according to the invention said coupling means comprises a pair of bellows elements interconnected by a flexible capillary tube, one of said bellows elements being associated with said thermal head and the other of said bellows elements being associated with said radiator valve, whereby operation of said thermal head causes said one of said bellows elements to be acted on, and corresponding action of said other bellows element causes said radiator valve to be acted on.
- In carrying out the invention it may be arranged that said radiator valve comprises the valve body of a thermostatic radiator valve, in which case said radiator valve may be disposed at one end of said heat emitter, said thermal head being mounted on a corresponding end of said enclosure, or alternatively said radiator valve may be disposed at one end of said heat emitter, said thermal head being mounted on the opposite end of said enclosure.
- An exemplary embodiment of the invention will now be described reference being made to the accompanying drawings, in which:
- Fig. 1 is a perspective view of a low surface temperature heat radiator in accordance with the present invention;
- Fig. 2 is a somewhat diagrammatic front cross-sectional view of the heat radiator of Fig. 1; and
- Fig. 3 is a view of a thermostatic radiator valve coupling kit for use in the low surface temperature heat radiators of Figs. 1 and 2.
- In Fig. 1 of the drawings there is shown a low surface temperature (LST) heat radiator 1 which is normally wall mounted and is connected in a conventional hot water central heating system, the LST heat radiator 1 comprising an
enclosure 2 and being connected to flow and returnpipes 3 and 4 respectively. As has been mentioned hereinbefore, conventional LST radiators have only been usable with remote adjustable or remote sensing type thermostatic radiator valves which are not appropriate for many applications. In order to overcome this problem the LST heat radiator 1 of Fig. 1 has been fitted with a thermostatic radiator valve (TRV) extension kit, as shown in Fig. 3, which enables thevalve head 5 of a conventional manually adjustable TRV to be mounted directly on theenclosure 2 of the LST radiator 1, the valve body of the TRV being mounted on the heat emitter in the usual way, as will hereinafter be explained. - In Fig. 2 of the drawings there is shown a front cross-sectional view of the LST heat radiator 1 of Fig. 1. The LST heat radiator 1 comprises a wall mounted
heat emitter 6 which is contained within theenclosure 2 and which is connected to the flow andreturn pipes 3 and 4 respectively of a conventional hot water central heating system. Theheat emitter 6 is connected to the flow pipe 3 by means of thevalve body 7 of a conventional thermostatic radiator valve (TRV). Thethermal head 5 of the TRV is mounted on theenclosure 2 of the LST heat radiator 1. Thevalve body 7 and thethermal head 5 are interconnected by means of anextension unit 8, shown in Fig. 3, which comprises afirst bellows unit 9 which is mounted through a hole in the side of theenclosure 2 and on which thethermal head 5 is fitted, and asecond bellows unit 10 which is mounted on thevalve body 7 in place of thevalve head 5, the first andsecond bellows units capillary tube 11. - The provision of the
extension unit 8 enables thethermal head 5 to be fitted as an integral part of the LST heat radiator 1, and the need for a remote adjustable thermostatic radiator valve is obviated. - It will be appreciated that the
thermal head 5 may be mounted at any convenient position on theenclosure 2 and may be at the same end as thevalve body 7 as shown in Fig. 2, or it may be at the opposite end as shown in Fig. 1, the coiledcapillary tube 11 being unwound as required. Conveniently, half-sheared blanking discs may be provided at both ends of theenclosure 2, and the appropriate blanking disc may be removed to mount thethermal head 5.
