Solar thermo-acoustic Stirling generating set capable of ceaselessly generating electricity day and night

Abstract

The invention relates to a solar thermo-acoustic Stirling generating set capable of ceaselessly generating electricity day and night. The generating set comprises a solar condenser, a solar heat absorber, a chemical energy storing device, a thermo-acoustic Stirling generator and a liquid metal heat transfer system, wherein the heat transfer system comprises that: a heat-absorbing heat exchanger consists of a substrate and a first hollow runner in the substrate and is positioned below the solar condenser; a generator thermal-head heat exchanger consists of a substrate and a second hollow runner in the substrate and is contacted with the high-temperature end of the thermo-acoustic Stirling generator; a chemical energy-storing heat exchanger consists of a substrate and a third hollow runner in the substrate and is contacted with the chemical energy storing device; an electromagnetic pump consists of a pump body, a fourth hollow runner in the pump body and an electromagnetic valve in the runner; and the first, second, third and fourth runners are sequentially communicated though pipelines and form a circulating runner in which liquid metal fluid is contained. The generating set is a self-sustaining self-adaptive high-efficiency low-grade energy-saving environmental-friendly heat generating set capable of ceaselessly generating electricity in 24 hours.

Description

technical field [0001] The invention relates to a solar power generation device, in particular to a solar thermoacoustic Stirling power generation device based on liquid metal transporting heat and chemical energy storage for day and night uninterrupted power generation. Background technique [0002] At present, due to energy shortage, the utilization of low-grade energy such as factory waste heat and automobile exhaust heat, as well as renewable energy such as solar energy and wind energy, has received unprecedented attention. However, there are still many technical obstacles restricting its large-scale practical application. One of the most critical links is the development of a high-efficiency, easy-to-use, economical, and self-sufficient energy generation system. [0003] In the current solar power generation, using photovoltaic cells to generate electricity is one of the most important modes. The basic structure of this power generation method is photovoltaic thin-film...
