Abstract
The utility model relates to a mirror reflection composite parabolic solar condenser which is characterized in that a receiver (3) is configured to form the mirror reflection composite parabolic solar condenser at the focus point (F) of a mirror reflection composite parabolic solar condensing surface (2), according to the position of the condenser, a hot vacuum tubular solar collector of mirror reflection composite parabolic internal focus (Figure 2) is arranged inside a glass tube, and a hot vacuum tubular solar collector of mirror reflection composite parabolic external focus or a all-glass vacuum tubular solar collector of mirror reflection composite parabolic external focus (Figure 3) is arranged outside the glass tube. The utility model has the advantages of using galvanized aluminum plate as the material of the mirror reflection composite parabolic surface, having simple processing and easy construction, increasing the working temperature of the collector, reducing the numbers of the collectors so as to lower the cost of the water heater, and in particular being important to exploit new hot vacuum tubular collector in domestic and industrial high temperature heat market successfully.
Description
The utility model relates to mirroring compound parabolic concentrator, according to the rim ray principle, the optically focused ratio of the incident ray in the given acceptance angle scope by imagination can be collected on the receiver.The experiment suburb really is faster than existing heat-pipe vacuum-tube (tabular thermal-arrest plate) heat absorption, and heat absorption efficiency exceeds 1.5 times, can reduce cost largely, can be used for the specific use of higher temperature.Therefore, be beneficial to and open up new life and industrial heat market, so be of wide application.
Solar water heater except that all-glass vacuum tube, is exactly a heat-pipe vacuum-tube at present.All-glass vacuum tube is cheap, but easily freezes, and easy scaling in the pipe is produced simply in addition, produces everywhere, and market has saturated gesture.Heat-pipe vacuum-tube has cold-resistant freezing, and starts soon, and advantages such as good heat insulation receive praises from customers, but price is higher, therefore, and the setter limited amount.How utilizing both advantages, especially improve the heat pipe vacuum tube collector operating temperature, increase efficient, reduce cost, is to break fresh ground to enlarge the key point that solar energy bases oneself upon with hot market.Solar energy mirror reflection compound parabolic concentrator is exactly to design for this reason.
The technical solution of the utility model is as follows: insert the solar energy mirror reflection compound parabolic concentrator of being made up of mirroring compound parabolic caustic surface (2) and reception body (3) in glass-vacuum tube (1), add that glass-vacuum tube (1) has just been formed in the solar energy mirror reflection compound parabolic optically focused heat pipe vacuum tube collector and be receiver (3), only externally set up optically focused heat pipe vacuum tube collector outside cover mirroring compound parabolic caustic surface (2) has been formed solar energy mirror reflection compound parabolic with the heat-pipe vacuum-tube.Same if be that receiver (3) is externally set up optically focused glass vacuum pipe heat collector outside cover mirroring compound parabolic caustic surface (2) has been formed solar energy mirror reflection compound parabolic with the all-glass vacuum tube.The material of mirroring compound parabolic caustic surface can simply process with zinc-plated aluminium sheet, it is applied in the solar thermal collector will reduces thermal-collecting tube, receives good effect.
The parabolic spheres intersect that the mirroring composite parabolic is an equation by two buses forms.Two symmetry axis NA.NB of Fig. 4 angle is 45 °, and composite parabolic is by two parabola M that common focus F is arranged
1A, M
2B and M
1O
1M
2The involute in one section garden is formed jointly.Article two, parabolical main shaft M
1B, M
2Angle is that 2a is an acceptance angle between A.By the principle of reflect focalization as can be known, parabola can become the convergence of rays parallel with its main shaft a bit, and parabolic cylinder can be the convergence of rays parallel with its main shaft (focal line) in alignment.When the solar energy of early being taken in is raised to certain height eastwardly, incident ray and M
2A is parallel, at this moment arrives parabola M
2Focus on the F point after the light reflection on the B.Move when the solar energy continuation, then light is just by M
2A is gradually to M
1The motion of B direction.Sunlight is at parabola M in this process
2Incidence angle on the B increases gradually, and angle of reflection also changes from small to big, so the hot spot after the reflection is just along FM
2Gradually to M
2Move down; And for parabola M
1A, situation is just in time opposite, and sunlight is at parabola M
1Incidence angle on the A diminishes gradually, angle of reflection also gradually from large to small, the hot spot after the reflection is along M
1F is to M
1Move to F side, as incident ray and M
1When B was parallel, the reflection post-concentration was at the F point.This shows that reverberation is to penetrate at FM all the time
1And FM
2Between, will receive body and be placed on herein, just can improve light-absorbing energy density effectively.
The utility model and existing all-glass vacuum tube and heat-pipe vacuum-tube are complementary and have just constituted new mirroring compound parabolic (inside and outside) light-focusing type all-glass vacuum tube water heater and mirroring compound parabolic light-focusing type (inside and outside) heat pipe type vacuum pipe water heater, because the utility model immersion heater, the temperature height, this is used for boiler and solar energy with regard to giving (reaching more than 95 ℃), drier, solar furnace, the exploitation of fields such as thermal power generation provides essential condition.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the solar energy mirror reflection compound parabolic light-focusing heat pipe formula vacuum tube collector of the utility model embodiment one.
Fig. 2 is the A-A profile of Fig. 1.
