The device is particularly suitable for aspects of heat-gathering power generation, heat supply, water supply, drying, heating, industrial heat exchange and the like. The device comprises a vacuum glass tube or a solar evacuated collector tube , a multi-curved surface special-shaped metal heat-exchanger tube, a superconducting medium, an evaporator, a frame, an upper shell and a lower shell, wherein the evaporator is provided with a totally-closed pressure-bearing case, the totally-closed pressure-bearing case is provided with a plurality of multi-curved surface special-shaped metal radiating tubes inside, and the lower ends of the multi-curved surface special-shaped metal radiating tubes are fixed on the bottom of the totally-closed pressure-bearing case through heat-exchanger tube connectors; the multi-curved surface special-shaped metal heat-exchanger tube is hermetically communicated with the multi-curved surface special-shaped metal radiating tubes in the evaporator and filled with the superconducting medium; and the vacuum glass tube or thesolar evacuated collector tube is sleeved on the outside of the multi-curved surface special-shaped metal heat-exchanger tube, the frame is arranged between the upper shell and the lower shell, and the upper shell is fixedly connected with the lower shell through the frame.

Description

technical field [0001] The invention relates to a solar thermal superconducting heat collecting device, which belongs to the technical field of solar thermal utilization. It is especially suitable for thermal power generation, heating, water supply, drying, heating, industrial heat exchange, etc. Background technique [0002] With the energy crisis in the world today, non-renewable resources such as oil, natural gas, and coal are being exhausted, and energy prices are also rising, which seriously affects the development of the global economy. The development and utilization of renewable energy and solar energy has become the focus of global attention. At present, there are heat-gathering (heating) devices using solar energy, which generally have small heat exchange area, slow heating speed, easy diffusion, less available heat generation, high input cost, and their own small application range. For example, the vacuum heat collector is only used as a heat source for productio...

AI Technical Summary

Problems solved by technology

At present, there are heat concentrating (heating) devices using solar energy, which generally have small heat transfer area, slow heating speed, easy diffusion, less available heat, high input cost, and their own small application range.

For example, the vacuum heat collector is only used as a heat source for production and domestic water. In hot summer, when solar energy is most abundant, the amount of hot water used is relatively small, resulting in waste of excess heat due to evaporation of water.
