SOLAR COLLECTOR HAVING AN INTEGRATED HEAT STORAGE

摘要

The present invention relates to a solar collector having an integrated heat storage (ICS) , in which between an involute mirror (6) and a transparent cover plate (3) a storage tank (5) for the storage of water is provided and in which the storage tank (5) is provided with a light absorbing fin (17) . At the lower end (8) near the circumference of the storage tank (5) the ICS according to the invention is provided with a fin system (9) which comprises a light absorbing fin (17) having a length in the longitudinal direction of the storage tank (5) of at least 10 cm, and the fin system(9) is designed such that the ICS lower end (8) is shielded to a great extent, as a result of which losses by radiation and convection of air are restricted. Thus, the fin systems (85) has a double function.
