    • A solar collector plate (1) comprises a dark-colored absorber plate (2) facing the sun, parallel wall sheets (4) arranged perpendicularly to the rear side of the absorber sheet (2), fixed thereto and also fixed to a support sheet (3) arranged parallel to the absorber sheet (2), whereby cavity channels (5) are provided between said sheets (2, 3, 4) for flowing cooling liquid (6) which is intended to transport heat away from the absorber sheet (2). In order to provide a good thermal contact between the liquid (6) and the absorber sheet (2) at a low rate of liquid flow in the cavity channels, the cavity channels (5) are filled with particles (7), which particles lift the cooling liquid (6) to contact with the absorber sheet (2) by means of a capillary effect.

    • A solar collector element having an inner tube through which a fluid can be passed, an outer glass tube enveloping the periphery of the inner tube and defining an evacuated space between the two tubes, and a solar selective surface coating deposited on the outer surface of the inner tube. The surface coating is deposited as three layers, an inner layer composed of a metal which exhibits high reflectivity in the infra-red spectral range, an outer layer composed of a material which behaves as a semiconductor at collector operating temperatures and an intermediate layer which is composed of a dielectric material. The materials of the respective layers are selected such that the refractive index mismatch between the inner layer and the intermediate layer is greater than it would be between the inner layer and the outer layer, in the absence of the intermediate layer, whereby the infra-red emittance of the collector element is reduced relative to that of an equivalent collector element having a two-layer selective surface coating.
    • 一种太阳能收集器元件,其具有可以流过流体的内管,外玻璃管,其包围内管的周边并且在两个管之间限定了抽空空间,以及沉积在该外管的外表面上的太阳能选择性表面涂层 内管。 表面涂层沉积为三层,由红外光谱范围内表现出高反射率的金属构成的内层,由在集电极工作温度下表现为半导体的材料构成的外层,以及中间层 由介电材料组成。 选择各层的材料使得在不存在中间层的情况下,内层和中间层之间的折射率失配大于内层和外层之间的折射率失配,由此红外 集电体元件的发射率相对于具有两层选择性表面涂层的等效集电器元件的发射率减小。
