Abstract

An Aluminium Panel Configured to be Secured to the Face of a Radiator to Project Heat From the Radiator Forward Into a Room A rectangular aluminium panel 2, preferably 3mm thick, 100mm wide, and 410mm long, with a high heat emissivity finish, configured to be secured to the face of a standard household radiator X using adhesive tape 3. The tape has high heat conductivity properties, preferably a foamed acrylic tape that is resilient and remains secure despite different expansion rates of the radiator and the aluminium panel. The tape is to be placed along the centre of the longer axis of the panel, which is then to be secured to a flat face Y at the top of a radiator. There are triangular viewing holes 5a, 5b, 5c & 5d to allow accurate positioning of the panel on a radiator. The panel is to be positioned at the top of a radiator, at the end closest to the hot feed pipe, to encourage heat projection out into the room.

Description

TITLE: Heat Exchange Device for Radiator The present invention relates to a device for a radiator.
Most space heating radiators used in central heating systems are formed of steel. Many of these have a flat wall section running horizontally adjacent the top and bottom of the radiator. Steel is not a good conductor of heat which limits the amount of heat that is transferred to a room by both radiation and convection. Also they are usually painted in a white gloss finish which reduces heat emissivity.
The invention seeks to provide a solution to this problem.
According to a first aspect of the present invention there is provided a heat exchange device for a radiator comprising an elongate aluminium panel adapted to be secured to the face of a radiator, said panel having a high heat emissivity finish.
Preferably the panel is white. Preferably the panel is a low gloss white.
Preferably the panel is about 3mm thick, and has a width of about 100mm and a length of about 410mm.
Preferably the panel has an adhesive strip to secure it to the radiator. The strip may be a tape. The tape may have high heat conductivity e.g. 5 to.8 W/mK e.g. .6 or.7. The tape may be a foamed acrylic tape. The strip may have a width substantially equal to the width of a flat wall section running horizontally adjacent the top of the radiator. The strip may be resilient to allow for different expansion rates between radiator metal and panel metal.
Preferably the strip has a width less than the width of the elongate panel and is located centrally along the length of the panel whereby the panel extends either side of the strip to provide wings either side of the strip.
Preferably the thickness of the panel to the width of the wings is between 1:9 to 1:15 e.g. 1:12.
Preferably the panel has viewing holes to position the panel on a radiator. The holes may be triangular. Preferably pairs of holes are provided either side of the strip.
According to a second aspect of the invention there is provided a heat exchange device for a radiator comprising an elongate aluminium panel adapted to be secured to the face of a radiator, and a heat conductive adhesive strip to secure the panel to the radiator.
Preferably the panel has a high heat emissivity finish. Preferably the panel is white. Preferably the panel is a low gloss white.
Preferably the panel is about 3mm thick, and has a width of about 100mm and a length of about 410mm.
Preferably the strip may be a tape. The tape may have high heat conductivity e.g. 5 to.8 W/mK e.g. .6 or.7. The tape may be a foamed acrylic tape. The strip may have a width substantially equal to the width of a flat wall section running horizontally adjacent the top of the radiator. The strip may be resilient to allow for different expansion rates between radiator metal and panel metal.
Tape may have high heat conductivity e.g. .5 to.8 W/mK e.g..6 or.7 Preferably the strip has a width less than the width of the elongate panel and is located centrally along the length of the panel whereby the panel extends either side of the strip to provide wings either side of the strip.
Preferably the thickness of the panel to the width of the wings is between 1:9 to 1:15 e.g. 1:12.
Preferably the panel has viewing holes to position the panel on a radiator. The holes may be triangular. Preferably pairs of holes are provided either side of the strip.
The invention also relates to a package of at least one panel as defined above and one or more clamps to secure the or each panel to a radiator.
An embodiment of the invention will now be described with reference to the accompanying drawings in which: Figure 1 shows a front view of a panel and Figure 2 shows a view of the panel on a radiator.
Referring to the drawings, there is shown a device 1 for a radiator X. Radiator X has have a flat wall section "Y" running horizontally adjacent the top and bottom of the radiator.
Device 1 has a rectangular elongate planar aluminium panel 2 adapted to be secured to the face of a radiator on the flat wall section "Y". Panel 2 is a low gloss white having a high heat emissivity finish. The panel is about 3rnm thick, and has a width of about 100mm and a length of about 410mm.
Panel 2 has an adhesive strip to secure it to the radiator in the form of an adhesive/self-adhesive tape 3 with high heat conductivity e.g. 0.5 to 0.8 W/mK e.g. .6 or.7. The tape may be a foamed acrylic tape. The tape is resilient to allow for different expansion rates between radiator metal and panel metal. The tape may be a tape VST 7064W produced by Hi-Bond Y Tapes Ltd. The tape 3 may have a width substantially equal to the width of a flat wall section Y of the radiator X, e.g. 32mm. The tape 3 has a width less than the width of the elongate panel and is located centrally along the length of the panel whereby the panel extends either side of the strip to provide wings 4A,4B either side of the strip.
Preferably the ratio of the thickness of the panel to the width of the wings is between 1:9 to 1:15 e.g. 1:12. So with a panel thickness of 3mm, the width of each wing may be 34mm.
Panel has two pairs of viewing holes 5A,5B 5C,5D to position the panel on a radiator. The holes may be triangular. The pairs of holes are provided either side of the tape 3.
In use heat is conducted into the panel 2 from the radiator "X" and radiated into the room from its surfaces. Also the wings 4A,4B are spaced from the front face of the radiator "X" by the thickness of the tape 3, and heat is convected up from the panel from the gap between the wings and the front face of the radiator. Because the panel is aluminium and has a high emissivity finish, the heat output of the radiator is enhanced. This leads to greater heating efficiency and reduced fuel consumption.
The device modifies the emitted heat distribution to become more biased towards projecting heat forward into the room and less into the supporting wall behind the radiator. This further enhances the heating effect.
The device exploits the 2 dimensional thermal gradient across the radiator in that a) the top of the radiator is hotter than the bottom, and b) the end of the radiator with the hot feed (flow) is hotter than the end with the return pipe. Fitting the panel at the top of the radiator above the hot feed locates it at the hottest point and hence maximizes the performance. Also the front of the radiator is the preferred location for the device for two reasons. Firstly the heat radiated by the panel is projected into the room whereas if it were on the rear the heat would be radiated into the wall. Secondly a plume of convected hot air rises above a radiator, and a significant portion of the heat is wasted in heating the wall. When the panel is placed on the front of the radiator the plume is drawn forward away from the wall such that less heat is lost.
It is envisaged that the panel would be sold in packs of several panels. Also removable clamps may be provided to secure each panel to a radiator flat wall section "Y" whilst the adhesive is setting.
The invention may take a form different to that specifically described above.
Further modifications will be apparent to those skilled in the art without departing from the scope of the present invention.
