Abstract
The invention relates to a solar collector, comprising: a cover layer to be directed toward the incident solar radiation; a system of tubes which is thermally coupled to the cover layer and through which heat transfer medium, in particular liquid such as water, can flow between a feed connection and a discharge connection; a substantially form-stiff carrier layer supporting the tube system and the cover later. The solar collector according to the invention has the special feature that: the cover layer consists of a weather-resistant plastic roof-covering foil; the tubes consist at least partially of a plastic material welded fixedly to the cover layer; the carrier layer is provided with recesses in which the tube system is accommodated.
Claims9
A method of assembling a solar collector integrated into a roof of a structure, comprising the steps of:
- providing a cover layer made of a weather-resistant plastic roof covering foil;
- providing tubes for forming a tube system for carrying a liquid heat transfer medium;
- providing a form-stiff carrier layer defining recesses for receiving the tube system;
- integrating the carrier layer into the roof of the structure such that the carrier layer serves as a supporting roof structure for the roof of the structure;
- forming the tube system within the recesses defined by the carrier layer after the carrier layer is integrated into the roof of the structure;
- welding the cover layer fixedly to the tube system with a welding head moved at a chosen speed along contact surfaces between the cover layer and the tube system, such that the tube system is coupled to the cover layer;
- and
- pressing the contact surfaces together such that melting, pressing, fusing and cooling occur in succession and the cover layer is bonded to the tube system.
