Abstract
A double-effect heat exchange solar vacuum collector tube is capable of increasing the heat collecting efficiency of a solar water heater. An inner tube of the double-effect heat exchange solar vacuum collector tube is extended out of (longer than) an outer tube by 60mm-150mm, the extended portion is used as a heat exchange wall, and the heat exchange speed of the vacuum tube and water in a heat insulation water tank is increased, so that the heat exchanger efficiency of the vacuum collector tube is increased.
Description
Technical field
The utility model relates to a kind of economic benefits and social benefits heat exchange solar vacuum heat-collecting pipe, has improved the collecting efficiency of vacuum heat collection pipe.
Background technology
At present, thermal-collecting tube in the market has common all-glass vacuum tube, glass metal structure for vacuum pipe, heat pipe type vacuum pipe, and all-glass vacuum thermal-collecting tube causes its thermal efficiency relatively low because its thermal starting is slower; And glass metal structure for vacuum pipe and heat pipe type vacuum pipe need metal tube (generally adopting copper tube) very high as its manufacturing cost of heat carrier, and the sealing by fusing of metal current and glass does not also thoroughly solve, and its life-span is still waiting further checking.
Summary of the invention
In order to solve the deficiency that existing vacuum tube exists, the utility model provides a kind of economic benefits and social benefits heat exchange solar vacuum heat-collecting pipe.This vacuum tube manufacturing cost is suitable with common all-glass vacuum tube, but the more common all-glass vacuum tube of its heat exchange efficiency is high.
The technical scheme that its technical problem that solves the utility model adopts is: allow the interior pipe of common all-glass vacuum thermal-collecting tube stretch (length) than outer tube and go out 60mm～150mm, the part of stretching out is as heat exchange wall, make the vacuum tube pipe on the basis of original heat convection, increase the conduction heat exchange, and the speed of conduction heat exchange is far above heat convection naturally, thereby accelerated the thermal starting of vacuum heat collection pipe, improved the heat exchange efficiency of vacuum tube, simultaneously, the part that vacuum tube puts in attemperater extends to some extent, has reduced the possibility to the vacuum tube sediment incrustation.
The beneficial effects of the utility model are on the basis that does not increase the vacuum heat collection pipe cost, to have improved the thermal starting and the heat exchange efficiency of vacuum heat collection pipe.And it is manufacturing process is suitable with the conventional vacuum thermal-collecting tube, and simple in structure.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a principle schematic of the present utility model.
Fig. 2 is a generalized section of the present utility model.
Fig. 3 is an organigram of the present utility model.
1. heat exchange walls among the figure, 2. inner glass tube, 3. the sun is selected absorber coatings, 4. vacuum interlayer, 5. cover glass tube, 6. supporting member, 7. air-breathing minute surface, 8. getter, 9. water, 10. storage tank, 11. sealing rings.
The specific embodiment
In Fig. 1, inner glass tube (2) seals with cover glass tube (5), and fixing by support member (6), the centre is vacuum interlayer (4), and air-breathing minute surface (7) and getter (8) are arranged in the interlayer, guarantees the vacuum of vacuum tube.Inner glass tube (2) outer wall adheres to the sun and selects absorber coatings (3), the vacuum heat collection pipe straight cutting is gone into storage tank (10), cover glass tube (5) is by sealing ring (11) and tank seal, heat exchange wall (1) is immersed in storage tank (10) inside, the conduction heat exchange takes place with water (9) in the storage tank (10), water and the water in the water tank (9) in the vacuum tube carries out heat convection simultaneously, improves the heat exchange efficiency of vacuum tube.
Claims (1)
1. novel economic benefits and social benefits heat exchange solar vacuum heat-collecting pipe, it is characterized in that: interior pipe range goes out outer tube 60mm～150mm, and the part that grows is as heat exchange wall.
