[0070] The third embodiment: on the outer tube wall of the backlight surface 1 of the outer glass tube of the solar vacuum heat collection tube, a reflective mirror surface 3 is bonded and compounded with a transparent glue 9, and the reflective mirror surface 3 is compounded with a composite substrate 10. The elastic electrical connection assembly 15 with a long-lasting getter is sealed and led out through the metal glass sealing head 16 . When in use, the conductor is connected to a DC power supply, so that the conductive heat-absorbing film of the energy conversion tube can be negatively charged, and through induction, the inner wall of the water chamber of the heat collecting tube is charged with positive charges and becomes acidic, preventing metal ions from forming on the inner wall of the heat collecting tube. A photovoltaic cell 18 is compounded on the transducing membrane plate 6 of the transducing tube 5 , and the wires of the photovoltaic cell 18 are sealed and led o...
