Problems solved by technology
When this kind of heat collecting tube is in use, it is necessary to use a pump or a pipe to extract the hot water in the heat collecting tube by suction, which is very inconvenient; and the end of the round head sealed into a hemispherical shape is also easy to be damaged, resulting in interlayer No longer in a vacuum, the heat collecting tube loses its heat collecting effect, which greatly reduces the durability of the heat collector

Embodiment Construction
[0010] The cross-sectional view of the heat collecting tube shown in Fig. 1, the inner glass tube (1) and the outer glass tube (2) of the heat collecting tube (3) are coaxially sleeved, and the inner and outer glass tube openings at both ends are melt-sealed to form a straight-through type, One end has a vacuum nozzle that protrudes outward. After the interlayer of the inner and outer tubes is evacuated through the vacuum nozzle, the seal of the vacuum nozzle is heated and softened, and the sealed vacuum nozzle is squeezed inward to form an inward convex. Vacuum lottery.
[0011] The structural diagram after the heat collecting tube is connected to the water tank shown in Fig. 2 is composed of the water inlet tank (4), the water storage tank (5) and the heat collecting tube (3). One end of the heat collecting tube (3) is inserted into the water tank, and the other end Inserted into the water storage tank, the water inlet tank communicates with the heat collecting pipe, and the...

The invention discloses a glass vacuum tube of a solar heat collector, and the glass vacuum tube consists of two layers of glass. The internal and external glass tube nozzles of a thermal-collecting tube are sealed by fusing to form the straight way type, and the vacuum state exists in an interlayer; wherein, one end is provided with a vacuum-pumping lot which bulges inwards. The ends of a plurality of thermal-collecting tubes enter into an inlet chest, and the other ends are inserted into a storage water tank. The pathway exists between the inlet chest and the thermal-collecting tube and between the storage water tank and the thermal-collecting tube; therefore, according to pressure difference between hot water and cold water in the thermal-collecting tube, the cold water can naturally flow into the thermal-collecting tube for heating without manpower, thus being very convenient.
Description
technical field [0001] The invention relates to a heat collecting tube, mainly a glass vacuum tube of a solar heat collector. Background technique [0002] At present, most of the existing solar collector glass vacuum tubes on the market adopt a single-ended opening, and the inner and outer tube openings at one end are annularly welded, and the other end vacuumizes the interlayer and seals it into a hemispherical round head. The heat collecting tube is shaped like an elongated thermos liner. When this kind of heat collecting tube is in use, it is necessary to use a pump or a pipe to extract the hot water in the heat collecting tube by suction force, which is very inconvenient; and the end of the round head sealed into a hemispherical shape is also easy to be damaged, resulting in interlayer No longer in a vacuum state, the heat collecting tube loses its heat collecting effect, which greatly reduces the durability of the heat collector. Contents of the invention [0003] ...
