The ceramic hollow solar collector plate changes the material and structure of the solar collector, its performance and use effect are far superior to the conventional solar collector. Conventional solar collectors mainly include glass vacuum tube type, metal flat plate type, concentrating collector, etc. The core part of the solar collector is borosilicate glass, copper, aluminum, stainless steel, solar absorption coating, etc. as the basic materials. The production of these materials consumes a lot of energy and the manufacturing cost is high. Due to the physical and chemical properties and structural characteristics of these materials, the heat collection efficiency of the products is continuously declining during use. The life is short. The hollow composite solar heat collecting plate completely changes the material, manufacturing process and product structure of the solar heat collector and hot water storage tank, thereby integrating the manufacturing cost, service life and construction of the solar water heater. Significant and fundamental changes have taken place in the unit cost of hot water production. The problem of economic feasibility of solar energy utilization is well solved, and it shows a large technical and economic advantage. The application of hollow composite solar collector technology is an important hope to make solar energy use cost lower than conventional energy use cost.
Features
(1) High efficiency: The solar absorption ratio of the surface of the hollow composite solar collector plate is 0.94, which is better than the absorption ratio of about 0.9 of the traditional solar collector, and more energy can be obtained per unit time;
(2) Non-decay: using high-tech nano-heat-absorbing materials, heat absorption and high efficiency will never decay;
(3) Long service life: The service life of the hollow composite solar heat collecting plate is dozens of times that of the traditional solar heat collecting device, and the integrated design can have the same service life as the building.
Application prospects
(1) Construction industry
Ceramic hollow solar heat collector plate can realize the integration of building, can build a solar roof to the sun-facing wall, and provide low-cost hot water, heating and air conditioning for the building. The building has a waterproof layer and an insulating layer, a waterproof layer on the roof of the ceramic hollow solar roof, and the insulating layer can be shared with the building.
Building energy consumption is mainly used for building heating, air conditioning, domestic hot water, etc. Obviously, the use of solar energy first considers using the roof and the sunny wall as the sunlight collection surface, delivering energy to the building at the shortest distance, integrating the solar device with the building To make the solar collector an organic component of the roof and the sunny wall, forming a solar roof and solar wall. In the past, solar collectors were mainly used for solar water heaters and solar hot water systems installed on the roof. The ceramic hollow solar panel can be used for the solar hot water system installed on the roof and the ceramic hollow solar roof. The ceramic hollow solar energy shares the thermal insulation layer and the waterproof layer with the ordinary roof, thereby having a lower overall cost.
(2) Manufacturing
Can provide preheating of boiler feed water, chemical industry, printing and dyeing, leather making, nest silk, milk processing, food processing, agricultural products and grain processing, drying, hot water and hot air required.
(3) Service industry
Can provide hot water for hospitals, hotels, restaurants, bathrooms, swimming pools, hairdressers, etc., as well as heating and air conditioning.
(4) Aquaculture
Can be used for large-scale marine aquaculture, pollution-free vegetable cultivation, and the construction of large-scale greenhouse solar drying system.
(5) Electric industry
One is to use ceramic hollow solar panels to build a solar heat collecting field, which can obtain a large amount of low-cost hot water for a long time. Refer to the traditional underground hot water power generation method for hot water power generation;
The second is to use ceramic hollow solar panels to build solar air ducts and generate electricity through hot air.
