Solar hollow flat plate collector

Abstract

The invention provides a solar hollow flat plate collector and belongs to the technical field of machinery. The solar hollow flat plate collector solves the problems that an existing solar hollow flat plate collector is complex in structure and high in production cost and the like. The solar hollow flat plate collector comprises transmitting glass, a heat collecting plate and a heat exchange pipe and further comprises a frame, two pieces of transmitting glass are arranged and are surface layer glass and bottom layer glass, and the surface layer glass and the bottom layer glass are fixedly connected to the positions of two ports of the frame respectively, a heat collecting cavity is formed between the frame and the two pieces of transmitting glass, the heat collecting plate and the heat exchange pipe are located in the heat collecting cavity, and light at the position of the surface layer glass is reflected to the position of the heat collecting plate through the bottom layer glass. The solar hollow flat plate collector has the advantages of being simple in structure and good in heat collecting effect and the like.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a solar hollow flat plate heat collector. Background technique [0002] my country is the world's largest coal producer and consumer. Coal accounts for about 76% of the commodity energy consumption structure and has become the main source of air pollution in my country. Vigorously developing new energy and renewable energy utilization technologies will become an important measure to reduce environmental pollution. Solar energy utilization technology is becoming more and more mature, especially in the development of solar collectors, many countries have special investment in research. At present in our country, solar collectors are widely used in hot water supply for hotels, schools, troops, hospitals, factories and mines, residential buildings, swimming pools and other projects, as well as solar heating, solar warm water farming, agricultural greenhouses, industrial It is also u...

Problems solved by technology

However, the conversion rate of the metal heat collecting tube with the structure of three or more wing-like fins is not high, and the average daily efficiency is about 60%.

[0004] At the same time, the shell of the heat collector needs to be made separately, and an insulation layer must be installed in the shell when it is used.

This makes the structure of the whole collector complex and the production cost is higher
