Embodiment Construction

[0028] Refer to attached Figure 1-8 , a solar heat collector, comprising a plurality of heat collection pipes 1 with one end closed, a bracket 2 for fixing the heat collection pipes, an incubator 3, a liquid inlet pipe 4 communicated with a low-temperature liquid, and a liquid outlet pipe communicated with the incubator 5. The liquid outlet pipe is set parallel to the outside of the liquid inlet pipe, the side of the liquid outlet pipe is sealed with the heat collection pipe, and the side of the liquid inlet pipe is sealed with a number of small metal pipes extending into the heat collection pipe 6. The heat collecting pipe and the liquid inlet pipe are connected through the small metal pipe to form a parallel unit group;

[0029] The heat collection tube includes a vacuum glass tube 11 and a metal tube 12. The end of the metal tube is closed, and the open end of the metal tube is equipped with a movable screw sleeve 13, which is sealed and connected with the external threade...

Abstract

A solar thermal collector comprises a plurality of heat collecting pipes with one ends sealed, a support fixing the heat collecting pipes, a heat preservation box, a liquid inlet pipe communicating with low-temperature liquid and a liquid outlet pipe communicating with the heat preservation box. The liquid inlet pipe is sleeved with the liquid outlet pipe in parallel. The side face of the liquid outlet pipe is connected with the heat collecting pipes in a sealed mode. The side face of the liquid inlet pipe is connected with a plurality of small metal pipes extending into the heat collecting pipes in a sealed mode. The heat collecting pipes and the liquid inlet pipe communicate through the small metal pipes to form a parallel-connection unit. The liquid inlet pipe communicates with the heat collecting pipes through the small metal pipes, the heat collecting pipes communicate with the liquid outlet pipe, and therefore installation is convenient and reliable; and a corrugated structure is arranged on each metal pipe in the corresponding heat collecting pipe and is bendable, so that installation and maintenance of the heat collecting pipes are simplified, and damage to vacuum glass pipes during installation is avoided.

Description

[0001] (1) Technical field [0002] The invention relates to a solar heat collector and belongs to the field of solar energy. [0003] (2) Background technology [0004] At present, the solar collector adopting the all-glass vacuum glass tube structure is composed of series collector tubes and parallel collector tubes, and a diversion tube is connected between the collector tube and the water inlet tube. Troublesome, it is easy to cause the rupture of the heat collecting tube during installation; the bracket is bulky, the pressure bearing capacity is poor, the maximum pressure bearing capacity does not exceed 0.6Mpa, and the pressure bearing capacity does not exceed 0.45Mpa when working under medium temperature saturated steam. It is used in the field of solar thermal There are major limitations. [0005] (3) Contents of the invention [0006] The technical problem to be solved by the present invention is to provide a solar heat collector that can effectively solve the above ...
