Embodiment Construction

[0038] Figures 1 and 7 show a flat-plate collector module 10.1 comprising a planar rectangular thin metal panel 1, a stopper device 30 of small capillaries 3.1...3.n extending parallel to each other and an adiabatic Polyurethane rigid foam insulation core4. The insulating material core 4 has a thickness of 25 mm. The material of the front exposed to the atmosphere and thus darker metal sheet panel 1 is a titanium-zinc alloy, here: a product of the applicant, RHEINZINK GmbH & Co. KG, Datteln. A higher degree of absorption is achieved by surface treatment, since less reflection occurs.

[0039] The thin metal panel 1 has the following dimensions:

[0040] -Length 300mm

[0041] -Width 400mm

[0042] - Thickness 0.8mm

[0043] The outer sheet metal panel 1 has two curved curved edges 16 , 17 for connecting adjacent sheet metal panels so that a stepped roof 40 according to FIG. 6 can be formed.

[0044] Small capillaries 3.1...3.n made of plastic each have an outer diameter ...

Abstract

The invention relates to a self-supporting, heliothermal flat collector module (10.1) comprising: - a sheet metal panel (1); - a register-type arrangement of small spaced-apart capillary tubes (3.1 ..3.n) that are penetrated by a liquid medium, said arrangement being located on the rear side (11.2) of the sheet metal panel (1), which lies opposite the side (11.1) that is to be irradiated; - and a thermally insulating core (4) of insulating material that is also disposed on the rear side. The small capillary tubes (3.1 ..3.n) are placed in a contacting manner upon a surface of the core (4) of insulating material, which is connected to the sheet metal panel (1) via an elastic adhesive layer (2). The small capillary tubes are at least partly embedded within the adhesive layer that is disposed between the sheet metal panel (1) and the core (4) of insulating material. The inventive sheet metal panel (1) is appropriately provided with two angled, bent edge profiles (16, 17) so as to produce a stair roof.

Description

technical field [0001] The present invention relates to a self-supporting solar thermal flat panel collector module comprising: [0002] - a thin metal panel; [0003] - a stop-type device comprising a plurality of small capillaries spaced apart from each other for flowing through a fluid medium, which is arranged on the back side of the thin metal panel facing away from the side to be irradiated; and [0004] - An insulating core of insulating material, which is likewise provided on the back. Background technique [0005] A flat-plate collector module of this type is known from DE-PS 100 43 295 by the applicant. The document basically provides that small capillaries are connected to thin panels by sputtering flowing metal particles. The glueing of thin panels equipped with small capillaries to a foam core is also known from DE-PS 100 43 295, although the details of the glueing are not described. [0006] Such gluing creates technical problems in solar thermal flat colle...
