Problems solved by technology

First of all, solar thermal has been developed in our country for many years, but most of them are concentrated in the field of solar hot water application. The technical development of solar hot air is relatively weak and has not been effectively utilized. However, the solar hot air system is not in terms of cost and technical stability. , solar heat utilization and other aspects have more obvious advantages; secondly, most of the domestic indoor heating currently adopts the form of water heating, gas heating or fresh air heat exchange, while water heating and gas heating still use electric heating or coal, waste oil and other fuels It is not environmentally friendly, and the fresh air heat exchange also needs to be heated by electric energy. Therefore, the above heating methods are very wasteful of energy.
[0003] Although the existing solar air heat collection devices also use glass tubes for heat collection, due to the limitation of their own structure, most of them have problems such as slow heat transfer speed, low efficiency, large air duct resistance and poor effect.
