Abstract
The utility model discloses an inner condensing full glass vacuum heat-collecting pipe, comprising an outer pipe of a heavy calibre, a common film-plating decalescence pipe (or a vacuum decalescence inner pipe), a reflecting board and a clamping element; the utility model is characterized in that the diameter ratio of the outer pipe and the inner pipe is 1:3.14. A circle involute-shaped condensing reflecting board is arranged in the vacuum layer between the outer pipe and the inner pipe, and the two surfaces of the condensing reflecting board take the inner pipe as the fundamental circle. According to the geometric property of the circle involute, the normal at any point of the involute-shaped reflecting board is tangent to the fundamental circle, so the beams from any direction to the involute-shaped reflecting board can be reflected on the inner pipe, and the focusing aim can be achieved. The utility model is of a larger concentrating ratio 3:1; a middle, high temperature(150 DEG C) demand can be satisfied by proper adjusting the elevation, a complex tracking device is absolutely not needed. A condensation end of the utility model is processed through necking technique to increase the heated area. The utility model has the advantages that the internal arranged reflecting board is of pollution and corrosion prevention, good concentrating effect and a long service life; and the utility model has no complex tracking device and low manufacturing cost; meanwhile, the utility model is of simple and convenient installation, stable operation, reliable performance, so the utility model can satisfy a middle, high temperature(150 DEG C) demand and can be widely used in solar devices such as a solar water boiler, a solar warmer and a solar cooler, etc.
Description
Technical field
The utility model belongs to application of solar, specifically a kind of interior light concentration type full glass vacuum heat collection pipe and application thereof.
Background technology
The existing history for many years of the application of common all-glass vacuum thermal-collecting tube in low-temperature solar energy heat collectors such as solar water heater.In recent years, in some solar energy medium and high temperature devices, also have and utilize all-glass vacuum thermal-collecting tube as heat collecting element, such as some solar boilers.Because the energy density of the sun is the end very, wants to obtain higher temperature, must install beam condensing unit additional.Again since the sun with respect to the earth in motion ceaselessly, therefore to continue to obtain more energy, also must keep adopting thermal element and be in all the time on focus or the focal line, so this kind equipment all installs the sunshine tracking device usually additional.
This present series products has two point defects:
1. no matter be that photoelectric tracking or mechanically tracking device not only increase cost, and its tracking accuracy is subjected to the influence of natural environment (as the resistance of wind) bigger, is difficult to guarantee that maintenance cost is higher that practicality is relatively poor service life.
2. external open parabolic optically focused reflecting surface is subjected to the pollution of dust easily, is the erosion that the minute surface aluminium sheet then is subject to acid rain, influences long-term result of use.
The utility model content
At the problem of above existence, the purpose of this utility model provides a kind of totally-enclosed interior light collecting vacuum heat collection pipe that does not need tracking means just can obtain higher temperature.Its technical scheme is: adopt the high-boron-silicon glass pipe of larger caliber to make outer tube, interior pipe can adopt common plated film endothermic tube, also can adopt vacuum heat-pipe.The diameter proportion of inner and outer pipe is 1: 3.14.Place between the inner and outer pipe vacuum layer one two-sided be the circle involute shape light gathering baffle-board of basic circle with interior pipe.According to the geometric properties of circle involute, the normal on the involute shape reflector on arbitrarily a bit must be tangent with basic circle, therefore any direction shine light on the involute shape reflector all can reflex on the pipe, thereby can reach the purpose of optically focused.The design's optically focused ratio be 3: 1 big slightly, as long as adjust the elevation angle, can reach the requirement of medium and high temperature (150 ℃), can remove complicated tracking means fully from.Condensation end is convenient to solid matter and is increased heating surface through the necking down processes.
The utlity model has following useful effect: the not contaminated and erosion of built-in reflector, spotlight effect is good, long service life; Can remove complicated tracking means from, low cost of manufacture; Simple installation, complete machine is stable, and dependable performance can satisfy the requirement that medium and high temperature is adopted heat fully, can be widely used in the devices such as solar boiler, solar heating, solar refrigeration.
Description of drawings
Fig. 1 is the vertical section schematic diagram of the utility model embodiment;
Fig. 2 is a cross sectional representation of the present utility model.
Among the figure: 1. vacuum heat absorbing pipe, 2. outer tube, 3. fastener, 4. light gathering baffle-board 5. attach net, 6. heat-conducting work medium.
The specific embodiment
As shown in Figure 1: dress on-aqueous liquid heat-conducting work medium 6 in the vacuum heat absorbing pipe 1, heat-conducting work medium 6 is heated to gasify and becomes liquid state mutually through vacuum heat-pipe 1 condensation end heat release, attaches net 5 and places vacuum heat-pipe 1 stage casing to be convenient to the phase transformation startup; Outer tube 2 one ends and vacuum heat-pipe 1 anterior cementing together, the centre vacuumizes; Circle involute shape light gathering baffle-board (4) places the vacuum layer of outer tube (2) and vacuum heat-pipe 1 formation, and by fastener 3 itself and vacuum heat-pipe 1 is in the same place with outer tube 2 relative fixed.
Claims (2)
1. light concentration type full glass vacuum heat collection pipe in a kind, comprise pipe, outer tube, reflector, fastener in the heat absorption, it is characterized in that: the diameter proportion of inner and outer pipe is 1: 3.14, place between the inner and outer pipe vacuum layer one two-sided be the circle involute shape light gathering baffle-board of basic circle with interior pipe.
2. light concentration type full glass vacuum heat collection pipe in according to claim 1, it is characterized in that: interior pipe can adopt the common endothermic tube of open type, also can adopt closed vacuum heat absorbing pipe.
