平板太阳能集热器的主要部件是吸收板。吸收板由做成一体的金属板和管构成,板的表面涂黑,以增强对太阳能的吸收。吸收板的底部和边缘用隔热材料隔热,以减少吸热板对周围大气的热损失。吸热板的上面盖有透明盖板,太阳光透过盖板,被吸收板吸收,同时它还限制盖板和吸收板之间的空气流动,减少吸收板的散热。传热流体(一般用水),通过吸收板中的管道流动,把吸收板吸收的太阳热传送
The main component of flat-panel solar collectors is the absorber plate. The absorber plate is made of a metal plate and tube made in one piece, and the surface of the plate is blacked to enhance the absorption of solar energy. The bottom and edges of the absorber plate are insulated with thermal insulation to reduce heat loss to the surrounding atmosphere by the absorber plate. The top of the heat absorption plate is covered with a transparent cover plate. The sunlight is transmitted through the cover plate and absorbed by the absorption plate. At the same time, it also limits the air flow between the cover plate and the absorption plate and reduces the heat dissipation of the absorption plate. The heat transfer fluid (typically water) passes through the duct in the absorber plate and transfers the solar heat absorbed by the absorber plate
