SOLAR HEAT COLLECTOR PANEL

摘要

A solar heat collector panel unit (10), comprising a heat collecting plate (40), a heat medium pipe (50), and a transparent insulator (20) which are formed integrally with each other. The heat collecting plate (40) is coated with an MOxNy (Ti or Al is substituted for M) selective absorbing film (30). The transparent insulator (20) is a silica aero-gel. Since the heat collecting plate (40) is buried in the transparent insulator (20), the strength of the transparent insulator (20) is increased. Accordingly, the transparent insulator such as the silica aero- gel can be used as the insulator of the solar heat collector panel unit, and the selective absorbing film (30), the heat collecting plate (40), and the heat medium pipe (50) can be sealed without clearance. As a result, the convection of air does not occur, excellent insulation performance can be provided, and the panel can be reduced in weight and simplified in structure. Also, since the solar heat collector panel unit (10) comprises a connector (60) and is connected to an adjacent unit (10) through the connector (60), the unit can be formed in a specified shape and/or size. The projected shape thereof is a regular polygon. When the units (10) are connected to each other, the shape and/or size thereof can be set freely, and the units can be formed not only in a plan shape but also in a three-dimensional curved shape by improving the material and shape of the connector (60).
