Abstract

In a plate radiator, the half-shells (1, 2) are offset against one another in such a way that narrow longitudinal beads (4) on alternate sides engage wide, vertical flow ducts (3). In the case of double-layered plate radiators, the longitudinal beads (4) opposite one another are consequently offset with respect to one another in each case. Convection plates (5) having recesses (6) over the longitudinal beadings (4) can be nested one inside the other in this manner. <IMAGE>

Panel radiators

The invention relates to a panel heating element according to the preamble of claim 1.

A panel radiator of this type can be found, for example, in CH-PS 267 897 '. The radiator owns Due to its large-area training, a large heat output, which is also provided by the outside applied convection plates is enlarged.

The heat output of the radiator should be increased further. In doing so, favorable manufacturing possibilities are to be expected be created, which come into play in particular in the production of a convection panel heater.

According to the invention this is achieved by a Radiator with the features mentioned in the characterizing part of claim 1.

Due to the offset assignment of the two identical half-shells, the longitudinal beads grip alternately into the vertical flow channels. They are welded to their base and subdivide the flow channels in two sub-channels. The radiator is very flat. It has a large heat exchange surface in contact with water, whereby its heat output is increased.

The main advantage, however, is that, in the case of double-layer panel radiators, the opposite longitudinal beads are offset from one another. When convection plates are placed on top, which form shafts above the narrow longitudinal beads, the shafts will also be offset from one another. This allows them to be nested within one another. In this way corresponds X is plus to the shafts via the longitudinal beads \ more bays between the wells. If the convection plates are correctly assigned, an entire shaft system with even distances between the elements is possible. With double-layer convection sheets, narrow shafts are to be created, which require the use of a fan for a fan coil unit. The convection output of a radiator of this type is significantly increased compared to conventional radiators.

This shaft system is also possible if one or both of the double-layer panel radiators outer panel half-shells without corrugations or smooth or with larger corrugation spacings than the inner ones Plate half-shells are provided.

The attached drawing shows exemplary embodiments of the invention. It shows:

Fig. 1: A cross section through a panel radiator and

Fig. 2: A cross section through a double-layer panel radiator with convection plates.

The panel radiator consists of two half-shells 1, 2, which are connected at their edges in a suitable manner. Each half-shell has elevations running from top to bottom to form wide, vertical ones Flow channels 3 and intervening depressions for the formation of narrow longitudinal beads 4. As a result of a staggered arrangement of the two half-shells 1, 2 grab the longitudinal beads 4 alternately into the flow channels 3, which they subdivide into sub-channels. This creates an extremely flat, highly effective radiator.

Convection plates 5 form shafts 6 over the longitudinal beads 4. The convection plates 5 lie over the whole Width of the flow channels 3. Before they are welded, they have a slight curvature 7 in the contact area inside. After the point they are then full. A thermal contact means 8 between the flow channel 3 and the convection plate 5 increases the heat transfer.

In the case of double-layer panel radiators, there are opposite longitudinal beads 4 due to the staggered arrangement the half-shells 1, 2 also offset from one another. The shafts 6 over the longitudinal beads 4 can be on this Nest one inside the other. A system of convection shafts is created, which is created by double-layer convection plates can be made even more effective.
