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...
