Solar collector made of plastic

The utility model relates to a solar collector made of plastic, in which between a supply pipe and a drainage pipe running parallel to it for the heat storage fluid a plate provided with a supply pipe and a discharge pipe connecting channels is attached to one area of the feed pipe or the discharge pipe, each having a longitudinal slot.

In a known embodiment of the type mentioned, the plate is mil? their edges having the mouths of the channels butt against the area of the supply or discharge pipe having the longitudinal slot and glued to it. Such a design has the disadvantage that the connection between the plate and the tubes is not very permanent is, especially since solar collectors are to be laid outdoors, which on the one hand results in not inconsiderable wind pressures and on the other hand are also exposed to snow and / or ice loads, whereby all loads can also occur at the same time.

Incidentally, solar panels are also known at which instead of slit open tubes in the longitudinal direction Shaped tubes are provided with sealing lips projecting away from the tube and adjoining the relevant opening. Such shaped tubes however, they are expensive both in terms of production and in terms of application, since they are used for sealing Special molded parts must be used in the end regions of the plate, to which the connection then has its own connection parts to the actual inlet or outlet pipe. In addition, the plate closes with her the mouths of the channels

having edges flush with the inner wall of the pipes, which can lead to a partial closure of the mouths of the channels by excess adhesive.

According to the utility model, the disadvantages of the known designs are in a solar collector of the type mentioned avoided by the fact that the plate is inserted into the longitudinal slots of the supply or discharge pipe, with their the mouths of the channels surrounding edges protrudes into the interior of the supply or discharge pipe, and with the Edges of the longitudinal slots and is glued or welded to the pipe areas adjoining them. This will be economically producible solar collectors made of plastic achieved, which high mechanical strength in the area of Have connection between supply or discharge pipe and plate. The strength of the slotted tube is according to the Gluing or welding the edges of the slot to the plate

over, fully restored as the platterd "ie gluing or Welding that absorbs the forces acting on the pipes, e.g. due to the pressure prevailing in them. Veiters become all forces acting transversely to the axial direction of the pipes, such as wind pressures, snow loads, and the like, from those delimiting the slots Areas of the tubes added, whereby by the gluing or welding of the plate with the adjoining the slot edges Pipe areas, u.zw. both on the outer wall and possibly also on the inner wall of the tubes, one substantial increase in the strength of the connection is achieved.

In the drawing is an embodiment of the utility model object shown. 1 shows a section through the solar collector running transversely to the longitudinal axis of the tubes. FIG. 2 is a section along line II-II of FIG. 1.

1 is the supply pipe and 2 is the discharge pipe for the heat storage fluid. Both tubes are made of plastic and each has one that runs in the longitudinal direction Seam slot 5 or 4. In the slots 3.4 is a likewise made of plastic, with the supply pipe 1 with the discharge pipe 2 connecting channels 5 provided

Plate 6 inserted, u.zw. so that the latter with theirs the | Orifices 5 ^{1 of} the channels 5 having edges 6 1 protrudes over the fs inner wall of the tubes ^{1, 2 into the interior of the same.} I The plate 6 is with the edges of the slots 3, 4 and with the | firmly glued to the pipe areas adjoining these edges _: or welded, whereby the glued or welded to

Claims (1)

PROTECTION CLAIM: A solar collector made of plastic, in which between a feed pipe and a discharge pipe for the heat storage fluid running parallel to it, a plate provided with a feed pipe and discharge pipe is attached to a respective area of the feed pipe and discharge pipe, each having a longitudinal slot, characterized in that that the plate (6) is inserted into the longitudinal slots (3, 4) of the supply or discharge pipe ( ^{1, 2} ) with its edges (6 1) surrounding the mouths (5 ') of the channels (5) into the interior of the supply line. Downstream pipe (1,2) protrudes, and is glued or welded to the edges of the longitudinal slots (3,4-) and to the pipe areas adjoining them.
