Solar vacuum glass heat collecting tube air heat collector

Abstract

The invention provides a solar vacuum glass heat collecting tube air heat collector, belongs to the field of solar air heating equipment, and particularly relates to a device which uses a solar vacuum glass heat collecting tube and a metal thermal tube which are combined for air heating and heat collecting. The solar vacuum glass heat collecting tube air heat collector is characterized in that a fan radiator (10) is arranged inside an air heat collecting chamber (9), the air heat collecting chamber (9) is connected with a condensing end at the top end of the metal thermal tube (4) through the fin radiator (10), and radiating fins (11) which are distributed in a radiating shape mode are arranged on the outer peripheral ring of the fin radiator (10). The solar vacuum glass heat collecting tube air heat collector has the advantages of being high in heat transmission speed, high in solar heat energy utilization ratio, good in sealing effect and the like.

Description

technical field [0001] A solar air heat collector belongs to the field of solar air heating equipment, and in particular relates to a device for air heating and heat collection by combining a solar vacuum glass heat collecting tube and a metal heat pipe. Background technique [0002] With the increasing shortage of coal, oil and other energy sources and the increasing pressure on environmental protection, countries have begun to promote renewable energy. Among them, the development and utilization of solar energy has become the hottest new favorite among renewable energy sources, and the development and utilization of solar energy has become an irresistible trend. . 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 cos...

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.
