Side outlet type solar thermal collector

Abstract

The invention discloses a side outlet type solar thermal collector which comprises a connecting box, an all-glass double-channel vacuum tube thermal collector, a vacuum tube bottom rack, a vacuum tube tail support and a bracket side plate, and is characterized in that an upper water collector pipe and a lower water collector pipe are horizontally fixed in the connecting box through a polyurethane thermal insulation layer; a water outlet of the upper water collector pipe and a water inlet of the lower water collector pipe serving as exchange ports of the collector and a heat exchanger are formed at one side or two sides of the connecting box; the all-glass double-channel vacuum tube thermal collector consists of an outer glass tube, a thermal absorption glass tube, an isolating glass tube and an inner glass tube; and the all-glass double-channel vacuum tube thermal collector, the connecting box, the vacuum tube bottom rack, the vacuum tube tail support and the bracket side plate form the solar thermal collector which is applied to the all-glass double-channel vacuum tube thermal collector. The side outlet type solar thermal collector has the advantages that the production difficulty is reduced, the breakage resistance of products is ensured during transport, the yield and perfectness ratio of the products are improved and the production cost is reduced, and is suitable for mass production and easy to mount and maintain.

Description

technical field [0001] The invention relates to solar energy utilization equipment, in particular to a side outlet type solar heat collector which converts solar energy into light and heat and has independent upper and lower water circulation channels. Background technique [0002] In the solar thermal utilization system, how to efficiently collect sunlight and convert it into heat energy is an important technical key. The applicant's invention patent "all-glass double-channel vacuum tube collector (patent number: 201010121560.4)" has independent upper and lower water circulation channels built inside the vacuum tube collector, which can generate a strong thermosiphon effect and is a separate The application of solar water heating system provides a solid application basis. As a new type of solar collector application, whether it is the overall design of the collector, the internal structure of the connecting box, or the connection between the all-glass double-channel vacuum...

AI Technical Summary

Problems solved by technology

[0003] In addition, during the development and application of the "all-glass dual-channel vacuum tube collector (patent number: 201010121560.4)", the applicant found the following shortcomings: 1. The top of the outer glass tube, heat-absorbing glass tube, and insulating glass tube The structure is complex, and it must be produced with the help of advanced lighting technology, which makes it extremely difficult to manufacture, which is not conducive to mass production and lower production costs

2. The glass flange on the top has a large thermal stress, and it is difficult to remove the stress by the general assembly line annealing system, so that the product cannot reach the expected yield

3. It is difficult to connect the inlet and outlet of the upper and lower water inlet and outlet with the upper and lower water collection pipes, which is not conducive to the installation and maintenance of the product

4. There is no positioning ring in the middle of the lower water collection pipe, and the inner pipe is easy to break with a little vibration, which becomes a major hidden danger in the transportation process
