Problems solved by technology

The utility model is characterized in that a U-shaped metal heat-conducting tube is added to the double-layer glass vacuum tube, and the heat-conducting tube is connected with transverse heat-conducting fins. The thermal efficiency of the invention is improved, but its structure is complicated and the cost is high. The main medium between them is air, and the thermal resistance is still very large

Abstract

The invention relates to a solar high-temperature air heater of a double-glass vacuum heat-collecting tube, belonging to the technical field of solar equipment and comprising an insulating layer, an air inlet cabin, an air inlet pipe, a connecting device and a plurality of double-glass vacuum heat-collecting tubes, wherein the air inlet cabin, the air inlet pipe and the connecting device are arranged in the insulating layer; the connecting device is fixedly connected with the air inlet pipe which is fixedly connected with the air inlet cabin; the outer part of the insulating layer is providedwith an iron box; the top end of the double-glass vacuum heat-collecting tube is positioned in the iron box, and the inner part thereof is provided with an elastic sleeve; the upper part of the elastic sleeve is sheathed in the air inlet cabin and is fixedly connected with the air inlet cabin; and the top end of the elastic sleeve is positioned above the air inlet cabin and is fixedly connected with the connecting device. The solar high-temperature air heater has simple structure, little heat resistance and high heat-collecting efficiency and can obtain medium-high temperature air with the temperature of 150 DEG C.

Description

technical field [0001] The invention relates to a heater in the technical field of solar energy equipment, in particular to a double-layer glass vacuum heat collecting tube solar high-temperature air heater. Background technique [0002] The limitation of conventional energy resources and the increase of environmental pressure have made many countries in the world strengthen their support for the development of new energy and renewable energy technologies. As a clean, environmentally friendly, efficient and inexhaustible new energy, solar energy has become a Important content of each country's sustainable development strategy. With the implementation of laws and regulations on energy conservation, emission reduction and building energy conservation in my country, solar heat utilization products have emerged one after another. Among them, solar air heating devices have been widely used in many fields, such as providing domestic hot water, heating, disinfection of medical supp...
