Abstract
A kind of water temperature rises faster all-glass vacuum thermal-collecting tube, belongs to solar water heater critical component technical field.All-glass vacuum thermal-collecting tube includes inside and outside two concentric circles borosilicate glass tubes, it is characterised in that：Thermal-collecting tube inner glass tube interior edge longitudinally set a both ends sealing corrosion resistant pipe, the 50~80% of a diameter of thermal-collecting tube inner glass tube diameter of corrosion resistant pipe, length be thermal-collecting tube inner glass tube length 65~95%.The preferred food-grade stainless steel pipe of corrosion resistant pipe, the both ends seal preferred stainless steel wafer or food grade silicone sealing-plug.The presence of corrosion resistant pipe reduces the water capacity of thermal-collecting tube inner glass tube, but the heat-sink shell area of outer surface is constant, so as to lift the programming rate of water in inner glass tube, accelerates the circulation of water, makes the hot water temperature in attemperater higher.
Description
Technical field
The utility model category solar water heater critical component technical field.
Background technology
The all-glass vacuum thermal-collecting tube for being currently used for solar water heater includes inside and outside two concentric circles Pyrex
Pipe, the outer surface of inner glass tube scribble the coating for selective absorption of high-absorbility and low-launch-rate, and interior outer glass pipe sealing part is used
High temperature is merged, and high vacuum is pumped between interior outer glass pipe.Sunshine is irradiated to inner glass tube appearance through outer glass pipe
On the heat-sink shell of face, heat energy is converted to, then heats the water in inner glass tube.Because layer is in high vacuum shape between interior outer glass pipe
State, the hot water in inner glass tube is greatly prevented to be improved collecting efficiency to surrounding environment dissipated heat.
After thermal-collecting tube inner glass tube heat-sink shell absorbs solar irradiation, the water of inner glass tube due to the difference of cold and hot water density,
Cold water sinks hot water liter, and hot water, which constantly ascends into attemperater, makes water circulation heating in case.Because the inner glass tube of thermal-collecting tube
Interior water capacity is larger, and in the winter time or light conditions are not that too ideally, the programming rate of water is slower in inner glass tube,
Thermal-collecting tube water circulating speed is caused to reduce, the hot water temperature in attemperater is relatively low.
The utility model content：
The purpose of this utility model is the shortcomings that overcoming existing product, there is provided a kind of water temperature rises faster all-glass vacuum
Thermal-collecting tube.
Structure of the present utility model：All-glass vacuum thermal-collecting tube includes inside and outside two concentric circles borosilicate glass tubes, its
It is characterised by：The corrosion resistant pipe of both ends sealing is longitudinally set in thermal-collecting tube inner glass tube interior edge, in a diameter of thermal-collecting tube of corrosion resistant pipe
The 50~80% of diameter glass tube, length are the 65~95% of thermal-collecting tube inner glass tube length.
The preferred food-grade stainless steel pipe of corrosion resistant pipe, the both ends seal preferred stainless steel wafer or food grade silicone
Sealing-plug.
Operation principle of the present utility model：The presence of corrosion resistant pipe reduces the water capacity of thermal-collecting tube inner glass tube, but appearance
The heat-sink shell area in face is constant, so as to lift the programming rate of water in inner glass tube, accelerates water circulation, makes in attemperater
Hot water temperature is higher.
The advantages of the utility model：Faster, the hot water temperature in attemperater is higher for water programming rate in thermal-collecting tube.
Brief description of the drawings
Fig. 1 is the structural representation of embodiment.
Embodiment
Embodiment：See Fig. 1.1 is commercially available all-glass vacuum thermal-collecting tube, the centre position in it, increases a longitudinal direction
SUS304-2B food-grade stainless steels pipe 2, two terminations 3 of stainless pipe 2 are closed with food grade silicone material, it is ensured that
Stainless pipe 2 is not intake in managing.The presence of stainless pipe 2 reduces the water capacity in the inner glass tube of thermal-collecting tube 1, but appearance
The heat-sink shell area in face is constant, so as to lift the programming rate of water in the inner glass tube of thermal-collecting tube 1, accelerates the circulation of water, makes guarantor
Hot water temperature in reservoir 5 is higher.The interior diameter of the inner glass tube of thermal-collecting tube 1 is 47mm, length 1700mm；Stainless pipe
2 a diameter of 28mm, length 1500mm.The both ends of stainless pipe 2 are fixed in the inner glass tube of thermal-collecting tube 1 with pipe clamp 4 respectively
The centre position of longitudinal direction.6 represent solar irradiation direction, and arrow 7,8,9 represents water flow direction.
Above example to the utility model only for being further described, and the scope of the utility model is not by being lifted
The limitation of embodiment.
