Embodiment Construction
[0010] The all-glass vacuum tube type natural flow heat collector shown in Figure 1 is composed of a water inlet tank (1), a water storage tank (2) and a heat collecting tube (3). One end of the heat collecting tube (3) is inserted into the water inlet tank, and the other end is inserted into the In the water storage tank, the water inlet tank communicates with the heat collecting pipe, and the heat collecting pipe communicates with the water storage tank.
[0011] The cross-sectional view of the heat collecting tube shown in Fig. 2, the inner glass tube (4) and the outer glass tube (5) 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 ...

The invention discloses an all-glass vacuum tubular natural flow solar collector, consisting of an inlet chest (1), a storage water tank (2) and a thermal-collecting tube (3). 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 the inlet chest, and the other ends are inserted into the 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 collector, mainly an all-glass vacuum tube type natural flow solar heat collector. Background technique [0002] At present, in the existing all-glass vacuum tube solar collectors on the market, most of the core components of the collector tube are single-ended openings, and the inner and outer tube openings at one end are ring-shaped and sealed, 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 durab...
