The heat collecting system comprises a water inlet main pipe, a water outlet main pipe and W solar vacuum tube units in parallel connection, wherein a medium can flow in the water inlet main pipe and the water outlet main pipe; each solar vacuum tube unit is respectively arranged between the water inlet main pipe and the water outlet main pipe and comprises solar vacuum tube sets connected in series, a medium conveying pump and a temperature sensor; each solar vacuum tube unit is internally provided with M solar vacuum tube pairs in parallel connection and is connected with an adjacent solar vacuum tube set through the water inlet main pipe and the water outlet main pipe, and each vacuum tube pair comprises two solar vacuum tubes in which U-shaped metal tubes are connected in series. Through utilizing the heat collecting system of the solar vacuum tube matrix, disclosed by the invention, heat can be efficiently acquired at a low cost; and the heat collecting system disclosed by the invention is suitable for the fields of industrial production, urban heat supply, thermal power generation and the like.

Description

technical field [0001] The invention relates to a solar vacuum tube matrix heat collection system, which belongs to the technical field of solar energy. Background technique [0002] Today's society advocates sustainable development, among which energy issues are the key issues restricting the sustainable development of human beings. As a source of energy, solar energy is inexhaustible and inexhaustible. The amount of solar radiation received by the earth every year is tens of thousands of times the total energy consumption of human beings. If this part of energy can be fully converted and utilized, it will be It will provide energy security for the sustainable development of mankind. Although a large number of R&D personnel have devoted a lot of creative labor to the utilization of solar energy, due to the low energy density and low quality of solar energy that humans can receive, it is still very difficult to directly utilize it on a large scale. [0003] At present, rel...
