• an auxiliary accessory 31 as a support for instance for an element of a floor at places where no corrugated sheets 11 can be installed, as for example in the vicinity of a collector of the device 10.
• auxiliary accessory 31 is provided with a U-shaped recess 37 at the side 36 opposite to the supporting surface 35, which recess 37 together with the bumpy plate 12 constitutes a passage 38, when the auxiliary accessory 31 has been placed on the bumpy plate 12, in which passage 38 a tube 2 can be installed, as is demonstrated in figure 15.
• an auxiliary accessory 31 is provided with several aforementioned U-shaped recesses 37 which are perpendicular to one another, so that tubes 2 can be passed through the auxiliary accessory 31 regardless of how the auxiliary accessory 31 is oriented in the bumpy plate 12.
• the invention is also regarding a device for heating and or cooling 10 which can be installed in walls or ceilings.
• prefabricated radiation panels 39 which can be configured according to the invention as represented in the figures 19 and 20.
• the represented radiation panel 39 It is characteristic for the represented radiation panel 39 that it is provided with a corrugated sheet 11 according to the invention on which tubes 2 have been attached by means of securing means 20 according to the invention, the tubes 2 being connected with one end to an ingoing collector 40 and with their other end to an outgoing collector 41.
• a radiation panel 39 with a bumpy plate 12 similarly to the embodiments intended for use in floor as represented in the preceding figures.
• the whole can be covered at one side by means of an insulating layer 42 which is for instance provided with a reflecting foil and at the other side for instance by an aluminum finishing plate 43 which looks nice, the whole being mounted in a molded edge 44.
• Figure 21 represents another embodiment of a device for heating and/or cooling 10 according to the invention.
• This other embodiment of a bumpy plate 12, which is represented in more detail in figure 24, has bumps 13 which are placed in a similar draught board like pattern as in the preceding embodiment.
• the pattern is however somewhat less dense than the pattern of the bumps 13 of a bumpy plate 20 according to figure 11.
• the dimensions of a cell of the draught board like pattern correspond to a multiple of the distance E between consecutive corrugations of the corrugated sheet 11.
• the pattern can also be described as being an array of rows of bumps 13, the distance K between consecutive bumps 13 in a row being a multiple of the distance E between the corrugations 18 of the corrugated sheet 11.
• the distance between bumps 13 in a row is in the embodiment represented in figure 24 four times said distance E.
• Another characteristic of the pattern is that the bumps 13 in consecutive rows of bumps 13 are offset to one another by a certain distance L.
• this distance is half of the distance K between the bumps in a row, which is still a multiple of the distance E between the corrugations 18 of the corrugated sheet 11, so that corrugated sheets 11 can be placed on the bumpy plate 12 according to directions which are perpendicular to one another.
• the rows of bumps 13 are offset to one another by the double of said distance E.
• the pattern is somewhat less dense is that the bumpy plate 12 is made more robust, the bumps 13 not being hollow as in the preceding embodiment.
• bumpy plates 12 according to this embodiment can still be stacked on top of each other in a compact way by stacking the plates 12 in pairs, the bumps 13 of each pair of plates 12 being directed towards one another.
• the pattern of the bumps 13 is such that the bumps 13 of a first bumpy plate 12 of an afore-mentioned pair of bumpy plates 12 fall in between the bumps 13 of the other bumpy plate 12 of the pair.
• the tops of the bumps 13 are flattened, so that the tops are less fragile, as a result of which the bumps 13 are not damaged easily during installation.
• the way tubes 2 are connected to the corrugated sheet 11 is also somewhat different than in the preceding embodiment .
• the corrugated sheet 11 is provided with holes 45 at the bottom of the gutters formed by the corrugations of the corrugated sheet 11.
• These holes 45 have a rectangular shape, which extends over the gutter between two consecutive tops of corrugations in a lateral direction, i.e. perpendicular with regard to the direction of the gutters.
• the holes 45 are sufficiently large in order to allow a securing means 20, which is represented in more detail in figure 22, to be introduced in a hole 45 with a consistent part of its shape.
• Such a securing means 20 has a cylindrical central part 46 in the shape of a kind of a small gutter, the borders 47 of which being provided with wings 48 by which the securing means 20 can be clasped into the hole 45.
• each wing 48 forms a supporting surface 21 which is situated nearby the free end 49 of each wing 48, the free ends being lips 49 to be hooked around the lateral edges of the rectangular shaped holes 45.
• These supporting surfaces 21 at both sides of the central part 46 of the securing means 20 are comparable to the supporting surfaces 21 of a securing means 20 as represented in figure 8, i.e. the supporting surfaces 21 provide support to the securing means 20 when it is placed in the corrugated sheet 11.
• the supporting surfaces 21 of a securing means 20 according to figure 22 are such that the angle A between the supporting surfaces 21 is bigger than the angle C formed by the flanks of a corrugation 18, so that, after the securing means 20 has been clicked in the hole 45 at the bottom of a corrugation 18, a permanent tension is obtained in the securing means 20.
• the intermediate part of the wings 48 between the supporting surfaces 21 of the wings 48 and the borders 47 of the central part 46 consists in this case of two other flat surfaces 50 forming an angle, which angle contributes in maintaining said permanent tension in the securing means when clicked in the holes 45.
• This particular shape of a securing means 20 is very- interesting since it can be easily made of a flat rectangular shape, preferably of spring-steel, simply by plying the rectangle into the particular shape represented in figure 22.
• the cylindrical central part 46 corresponds to the shape of the tubes 2 and has preferably a cross-section which is somewhat smaller than the cross-section of a tube 2 in order to augment the clamping force.
• the distance between the borders 47 of the securing means 20 is important and is preferably smaller than the diameter of a tube 2.
• the central part 46 extends somewhat below the surface of the corrugated sheet 11 in order to ensure the contact between a tube 2 and the corrugated sheet 11.
• Securing means 20 have also the advantage that only one securing means 20 is needed for each connection of a tube 2 to the corrugated sheet 11 in stead of two securing means 20 as was the case with the other type of securing means 20 described above.
• Figures 25 and 26 represent a part of another embodiment of a device 10 for heating and/or cooling wherein two kinds of bumpy plates 12 are applied.
• bumpy plates 51 are installed having bumps 13 which are placed in rows at a distance from one another which is smaller than the diameter of a tube 2, so that tubes 2 can be clasped in between the space formed between two rows of bumps 13 as is demonstrated in figure 26.
• bumpy plates 51 will be installed at edges 52 of rooms or at collectors of the device 10.
• the present invention is in no way limited to a device for heating and/or cooling described as an example, nor to the bumpy plate and radiation panel described as an example, which can be used in such a device, nor to the method of installing such a device for heating and or cooling, but such devices and parts of the device as well as the aforementioned method may be realised according to different alternatives without departure from the scope of the invention.
