1. a heat conduction and thermal insulation device of vacuum collector tube is the tube chamber of a sealing, and it is characterized in that:

  • be filled with a certain amount of phase change medium material in the tube chamber of sealing, the phase change medium material is water;

    Or the sealing tube chamber is built-in with weight material, is packaged with its overall weight of sealing tube chamber of weight material greater than the weight of equal-volume water, and the weight material of sealing tube chamber encapsulation contains a certain amount of water, and sealing tube chamber water content looks its operating pressure and temperature determines;

    The closed end of sealing tube chamber has certain bearing capacity, and sealed tube lumen footpath is smaller and adapt to vacuum heat-collecting tube chamber internal diameter, and heat conduction and thermal insulation device of vacuum collector tube is installed on the bottom in all-glass vacuum thermal-collecting tube chamber, and its device body is corresponding with the elastic metallic support card.
