Abstract
The invention discloses a high-energy efficiency solar thermal collector. A heat absorbing fin is positioned in a low-pressure vacuum layer and connected with an inner glass tube; two ends of the inner glass tube are sealed; and heat-conducting medium which is liquid at a normal temperature state is contained in the inner glass tube. As the heat absorbing fin is mainly utilized for absorbing heat and a traditional inner glass tube is not utilized for absorbing heat, thus the diameter of the inner glass tube is smaller, the heat-conducting medium contained in the inner glass tube is less, so that less heat can be discharged for use from the inner glass tube, heat stored in a water tank is more, and the purpose of high energy efficiency is achieved.
Description
Technical field
The present invention relates to a kind of heat-collecting part glass-vacuum tube of solar water heater.
Background technology
At present, the structure of the heat-collecting part glass-vacuum tube of solar water heater does, is made up of inside and outside layer glass pipe, between the layer glass pipe, is evacuated, and scribbles heat-sink shell at the outer surface of inner layer glass tube.When the user uses solar water heater, can only emit the hot water in the water-heater water tank, and can not emit the hot water in the glass-vacuum tube, and the volume of the inner glass tube of glass-vacuum tube is bigger, the out of use hot water volume of user is also just relatively large.
Summary of the invention
For a large amount of hot water in the inner glass tube that overcomes the existing glass vacuum tube can not be emitted use; The deficiency that efficiency is low, the present invention provides a kind of high energy efficiency solar thermal collector, and the inner glass tube volume of this high energy efficiency solar thermal collector is little; So it is relatively also just few to emit heat in it.
The technical solution adopted for the present invention to solve the technical problems is: the high energy efficiency solar thermal collector comprises inner glass tube, outer glass pipe; One end of inner glass tube and outer glass pipe seals the formation free end respectively; The other end of inner glass tube and outer glass pipe seals; Be the low-voltage vacuum layer between inner glass tube and the outer glass pipe, a heat absorption fin is positioned at the low-voltage vacuum layer, and the heat absorption fin links to each other with inner glass tube; The inner glass tube sealed at both ends, and contain in the inner glass tube under the normal temperature state and to be liquid heat-conducting medium.The course of work of this high energy efficiency solar thermal collector does, solar energy directly is radiated on the heat absorption fin, and the heat absorption fin is delivered to heat in the less inner glass tube of diameter, through the circulation of the heat-conducting medium in the inner glass tube heat is imported in the water tank.
The invention has the beneficial effects as follows; Because the main heat absorption fin that relies on absorbs heat, rather than relies on traditional inner glass tube to absorb heat, can make the diameter of inner glass tube less like this; The heat-conducting medium that is contained in the inner glass tube is also just less; Thereby the heat that can not emit use in the inner glass tube is also less, and heat stored in the water tank is more, thereby reaches the purpose of high energy efficiency.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is a structure principle chart of the present invention.
1. outer glass pipes among the figure, 2. inner glass tube, 3. low-voltage vacuum layer, 4. heat absorption fin, 5. water.
The specific embodiment
