Abstract
The utility model relates to a heat discharging and collecting component of a solar device, which comprises a through type metal flow channel glass metal heat collecting pipe and expansion joints coaxially connected with the two ends of the heat collecting pipe. When the combined through type solar heat collecting pipe is arranged transversely for use, a metal inner pipe is matched with a metal flange through a clearance, thereby supporting a shield glass pipe, and the flange and the shield glass pipe can not be damaged by the radial thermal expansion of the metal inner pipe due to the clearance matching. When the temperature of the metal inner pipe is heated as a result of the absorption of solar energy by a solar selective absorption coating on the surface of the metal inner pipe, and the expansion load caused by the thermal expansion of the metal inner pipe can be discharged through the elastic stretching of a bellows, thereby eliminating the damage to the shield glass pipe caused by the thermal expansion of the metal inner pipe; and the axial movement of a connecting ring welded with the metal inner pipe can be transmitted to the bellows on the expansion joints through a seal ring connected with the connecting ring, and the damage to the system caused by the axial expansion of the metal inner pipe can be eliminated through the axial deformation of the bellows.
