Description

technical field [0001] The invention belongs to the technical field of solar energy, in particular to a comprehensive system for thermal utilization of solar energy. Background technique [0002] With the massive development and utilization of fossil energy, the energy is depleted day by day, and the environmental pollution is becoming more and more serious. Stirling engine is an engine with a wide range of energy sources. It can be driven by almost any high-temperature heat source, such as solar energy as a heat source, which can greatly reduce energy consumption and environmental pollution. [0003] The Stirling engine is an engine that outputs power through the cycle of cooling, compression, heat absorption and expansion of the working medium in the cylinder. When working, the working medium is pushed by the displacer in the heat displacement cylinder, and flows back and forth between the cold end and the hot end. As air flows to the hot end, it expands and pushes the p...

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that the concentrator at the hot end of the existing solar Stirling engine does not have the function of fixing the focus, so that the heat utilization efficiency of solar energy is low, and the cold end is directly cooled by air, which is greatly affected by external factors and dissipates heat. The effect is not obvious, so that the temperature difference between the hot end and the cold end of the engine is small, which leads to the problem of low solar heat utilization efficiency and energy waste of the engine, and provides a solar energy with good heat dissipation effect and high sunlight and heat utilization efficiency.
