Photovoltaic and photothermal integrated vacuum tube

The invention provides a photovoltaic and photothermal integrated vacuum tube which comprises a glass outer tube, a glass inner tube, a first solar battery panel, an arc glass partition plate, a sealing cover, a second solar battery panel, nanofluid, a micro pump and a thermal diode. The glass outer tube and the glass inner tube are coaxial round sleeve pipes, and a vacuum interlayer is formed between the two tubes. The sealing cover is arranged at the front end of the vacuum tube, and a closed circulating fluid channel is formed among the sealing cover, the arc glass partition plate and the inner wall of the glass inner tube. The first solar cell panel is attached to the outer wall of the glass inner tube. The arc glass partition plate is arranged in the glass inner tube. The second solarcell panel is attached to the concave face of the arc glass partition plate. The circulating fluid channel is filled with the nanofluid. The thermal diode is arranged at the front end of the vacuum pipe. The micro pump is ar
