Among the present invention, an end of inner layer metal rectangular tube can stretch out from outer layer glass tube, so that the heat-exchange device in the level metal rectangular pipe is installed.
The present invention is by the vacuum heat-insulation chamber, thereby the front that solar panel can not occur has air to produce the problem of high temperature, problem by the glass outer tube conduction dissipated heat in front can not appear yet, heating on the solar panel can only be by thereafter level metal rectangular pipe and heat-exchange device conduction wherein be installed and exchange away, thereby output hot water.
From photo-thermal effect, the infrared band in the solar spectrum directly produces thermal effect, and exhausted most luminous energy can not directly produce heat.Among the present invention, the outer back side or all other three faces of solar panel are not installed on level metal rectangular pipe, are coated with the absorber coatings material that last layer can fully absorb sunlight heat energy, can absorb sunlight fully.
A measure of the present invention is by utilizing the approaching alloy of a kind of thermal coefficient of expansion and glassy phase, and this alloy and glass outer tube can be taked fire envelope, hot pressing or gluing mode sealed attachment; This alloy and level metal rectangular pipe can adopt the mode sealed attachment of welding, thereby a kind of stable performance, reliable vacuum heat-insulation chamber are provided.It is obvious that this sealed attachment mode can solve the thermal dilation difference of metal and glass effectively, and problem that can't sealed attachment further satisfies Salar light-gathering, the problem that pyroelectricity cogeneration etc. utilize.
In sum, the present invention has following remarkable advantage:
1. Du Te vacuum heat-insulation chamber has guaranteed outstanding thermal insulation, has protected solar panel, has improved the reliability of vacuum heat-collecting generating.
2. maintainability has been considered in the design of the mounting means of heat-exchange device, is convenient to install, dismantle.
Between level metal rectangular pipe and the glass outer tube with the very low materials for support of a kind of conductive coefficient; The outer back side or all other three faces of solar panel are not installed on the level metal rectangular pipe, are coated with the absorber coatings that last layer can fully absorb sunlight heat energy, these two kinds designs have reduced dissipation of heat energy on the one hand, have improved solar energy utilization ratio on the other hand.
