Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the drawings.

[0033] Such as figure 1 As shown, a glass-metal vacuum heat collecting tube includes a metal inner tube 1, a glass outer tube 9, a head 3, a head fixing plate 6 and a sealed connection device. The total length of the metal inner tube is between 1m-3m. The metal inner tube 1 is sheathed inside the glass outer tube 9, and both ends extend beyond the length of the glass outer tube 9. Both ends of the metal inner tube 1 have a head 3, and a head fixing plate 6 is connected to the head 3 and the glass outer tube 9 In between, each interface is sealed by a sealed connection device, and a closed space is enclosed by the metal inner tube 1, the glass outer tube 9, the head 3 and the head fixing plate 6, and the inside is evacuated to basically eliminate the metal inner tube 1 and the glass outer tube 9 convection heat exchange. The sealing connection device includes a sealing flan...

Abstract

The invention relates to a glass metal vacuum collector tube which comprises a metal inner tube (1), a glass outer tube (9), sealing heads (3), sealing head fixing discs (6) and sealing connecting devices, wherein the metal inner tube (1) is arranged in the glass outer tube (9) in a penetrating way, both ends of the metal inner tube (1) extend and exceed the length of the glass outer tube (9), two sealing heads (3) are respectively arranged at the both ends of the metal inner tube (1), a sealing head fixing disc (6) is connected between each sealing head (3) and the glass outer tube (9), each interface is sealed by the sealing connecting device, and a sealed space is enclosed by the metal inner tube (1), the glass outer tube (9), the sealing heads (3) and the sealing head fixing discs (6) and is vacuumized. The glass metal vacuum collector tube has a structure suitable for a high temperature difference and can resist deforamtion, prolong the service life and enhance the heat collecting efficiency.

Description

Technical field [0001] The invention relates to a heat collection device in heat supply technology, in particular to a vacuum heat collection tube. The invention belongs to the technical field of solar energy utilization. Background technique [0002] Energy is an important material basis for the development of the national economy and the improvement of people’s living standards. With the sustained rapid growth of the economy, the limited resources of fossil energy and the environmental problems caused by the development and utilization of fossil energy have increasingly become constraints on the sustainable development of the economy and society. factor. Speeding up the development and utilization of renewable energy is an important way and measure to solve energy and environmental problems. Solar energy is a clean, non-polluting and inexhaustible energy source. It has received more and more attention from the whole society. It is one of the fastest-growing renewable energy s...
