[0002] A flat-plate solar collector is a device that absorbs solar radiation energy and transfers heat to the working fluid. It is a special heat exchanger. Flat-plate collectors have been widely used in many fields such as domestic water heating, swimming pool heating, industrial water heating, building heating and air conditioning.

[0003] Upon investigation, the EU invention patent discloses a lightweight vacuum solar thermal panel (publication number: WO2010023074A1). The present invention relates to a lightweight vacuum solar collector panel. The existing vacuum solar collector panel includes a flat vacuum sealed shell, a heat absorber and a pipe that enters and exits the shell and is connected to the heat absorber. Solar radiation enters the shell through the glass plate, is absorbed by the heat absorber and converted into heat energy, and then transferred to the pipe and the heat conduction liquid therein. In order to prevent convection from transferring heat to the external environment, the vacuum state in the shell is maintained.

[0004] Although the above patent adopts the arrangement of a flat vacuum sealed housing to prevent heat from being transferred to the external environment by convection, the vacuum state inside the housing is maintained;
