<p>Collector comprises a casing which is radiation-permeable on the irradiated side but thermally insulated at its other surfaces. In the casing there is a heat transfer element through which a heat carrier medium may flow. The heat transfer element consists of 2 metal lamellae, parallel to the plane of radiation transmission, which are provided with depressions in which a pipeline carrying the heat carrier medium is arranged. The pipeline consists of a thin walled, heat- and corrosion-resistant, plastics tube whose length and cross-section correspond to the channel defined by the depressions of opposite, heat-conductingly connected, metal lamellae. It is provided with connecting nipples which are fixed at the collector. It can be used for domestic heating, including heating of water. Depending on choice of heat carrier medium, it may also be used for cooling purposes. Collector, constructed as claimed, is simple and inexpensive to produce and of low wt. It minimises any problems traditionally connected with corrosion caused by water flowing through it.</p> |
