Description

technical field [0001] The invention relates to the technical field of solar energy applications, in particular to a solar high temperature heat conduction system. Background technique [0002] China's solar energy industry is developing very rapidly, but its application fields are basically concentrated in the low-temperature civilian field. Since 70% of China's energy consumption is used in industry, the popularization of solar energy in the low-temperature civilian field cannot alleviate my country's energy shortage and lagging behind in emission reduction. Since the 1980s, China has begun to develop solar energy utilization technology at medium and high temperatures, and has achieved Substantial progress has been made, with breakthroughs in a number of new technologies such as trough concentrators, high-temperature vacuum heat collectors, high-temperature heat-collecting working fluids, and phase-change energy storage materials, making the application of solar energy in t...

Problems solved by technology

[0003] At present, the system that uses solar energy to supply heat in the market is based on the principle of using water circulation to circulate solar energy to obtain heat. The technology using water circulation has the following obvious shortcomings: 1. The circulating water requires a special circulating pump and controller and consumes a lot of electricity. , otherwise the transmission distance is short, and it is difficult to separate the heat collector and the water tank to an ideal distance; 2. The system passes through multi-stage sensible heat transfer, the temperature difference is large, the thermal efficiency is poor, the heat gain temperature is low, and the heat transfer and heat collection effects are not good. Moreover, the energy density is small, which makes it difficult to adapt to high-temperature applications such as absorption refrigeration; 3. The system is complex, the heat transfer coefficient is low, the components and pipes are large in size and consumables, and the manufacturing cost is high; 4. The life of circulating pumps and heat pipes is difficult to exceed 15 years. Poor maintainability and economy
