Description
Technical field
The utility model relates to the outer eccentric vacuum heat collection pipe solar water heater of minute surface that pastes.
Background technology
Be utilization and extention solar energy, need the more solar thermal utilization product of Development and Production, comprise the heat collector of the eccentric vacuum heat collection pipe of various employings.
Summary of the invention
The purpose of this utility model is that the outer eccentric vacuum heat collection pipe solar water heater of minute surface that pastes will be provided.
The technical scheme in the invention for solving the technical problem: with adiabatic water tank, paste the eccentric vacuum heat collection pipe of minute surface and support outward, forms an outer minute surface off-centre vacuum heat collection pipe solar water heater that pastes.The outer eccentric vacuum heat collection pipe of minute surface that pastes is tightly connected into an eccentric chuck by the cover glass tube that end circle seals with the inner glass tube nested arrangement, and sealed-off after the inner baking of the eccentric chuck exhaust is made, and is manufactured with absorbing film on the described inner glass tube.The described outer eccentric vacuum heat collection pipe of minute surface that pastes is at the cover glass tube outer surface half slot shape object that is connected, the concave surface of described half slot shape object is manufactured with minute surface, and the inner glass tube of band absorbing film is connected with the minute surface optically focused on the described half slot shape object concave surface.
Can also make the described outer minute surface that pastes on the eccentric vacuum heat collection pipe of minute surface is magnetron sputtering aluminium film mirror; Described half slot shape object is made of anodised aluminium sheet, and bonds with edge and the cover glass tube of silica gel with described half slot shape object.
The beneficial effects of the utility model comprise: with compare in the technology of cover glass tube inwall high-frequency induction AM aluminum metallization film, make the semicircle minute surface in the outside of cover glass tube, the design freedom of technology increases greatly.Can directly adopt the existing a large amount of vacuum magnetic-control sputtering filming equipments that use once tens of make minute surface at the cover glass tube outer surface, work efficiency is increased to thousands of from about 500 of unit every day.Production efficiency increase substantially the reduction that means product cost.Eccentric vacuum heat collection pipe, the diameter of its inner glass tube is about half of cover glass tube, utilize cover glass tube upper semi-circle minute surface optically focused thermal-arrest to the absorbing film on inner glass tube surface, have advantages such as less with material, that the few little startup of the little heat waste of heat sink little surface area of the little water of inner glass tube cavity is fast.Described half slot shape object is made of anodised aluminium sheet, and weather resistance is good.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the outer eccentric vacuum heat collection pipe solar water heater structure of a minute surface schematic diagram that pastes.
1. adiabatic water tanks among the figure; 2. paste the eccentric vacuum heat collection pipe of minute surface outward; 3. support; 4. cover glass tube; 5. inner glass tube; 6. half slot shape object; 7. minute surface.
The specific embodiment
Fig. 1 provides an embodiment of the present utility model.
Among Fig. 1, with adiabatic water tank 1, paste the eccentric vacuum heat collection pipe 2 of minute surface and support 3 outward, forms an outer minute surface off-centre vacuum heat collection pipe solar water heater that pastes.The outer eccentric vacuum heat collection pipe of minute surface that pastes is tightly connected into an eccentric chuck by the cover glass tube 4 that end circle seals with inner glass tube 5 nested arrangement, and sealed-off after the inner baking of the eccentric chuck exhaust is made.Be manufactured with absorbing film on the inner glass tube 5.At the cover glass tube 4 outer surfaces half slot shape object 6 that is connected, half slot shape object 6 adopts anodised aluminium sheet to make; The concave surface magnetron sputtering aluminium film of half slot shape object 6 forms a minute surface 7, and the inner glass tube 5 of band absorbing film is connected with minute surface 7 optically focused on half slot shape object 6 concave surfaces.And with silica gel with the edge of half slot shape object 6 and cover glass tube 4 bondings.
Optically focused described in the utility model connects, and refers to the tubulose absorber, such as the axial line of inner glass tube 5 is mobile near cover glass tube 4 but do not contact in order to avoid form heat bridge with cover glass tube 4 and cause heat-energy losses from the top down along the symmetrical plane of minute surface 7.Can recognize from Fig. 1: enter the sunlight of cover glass tube 4 the latter halfs, mid portion directly for example changes into heat energy with the inner glass tube 5 of absorbing film at absorber; The overwhelming majority in the two side portions once or repeatedly changes into heat energy on the reflection arrival absorber through minute surface 7.The a small amount of sunlight that passes from the gap between absorber and the cover glass tube 4 might pass through the reflection of minute surface 7 and escape from cover glass tube 4.Usually the gap width between tubulose absorber and the cover glass tube 4 is 1 to 2 millimeter.
Solar energy heat collector should face the sun usually and settle.
