Description

Solar energy heat collector

Technical field

The utility model relates to field of solar energy, is meant solar energy heat collector especially.

Background technology

The sun is the natural origin of energy.Why the biology that each lives on the earth has the ability that plays a role, and is even its existence, all is owing to directly or indirectly come from the energy of the sun.Our earth is in almost 100,000,000 miles place from the sun.The radiant energy that it intercepted is less to being difficult to put letter (approximately 3/10000000ths), and so little some energy are in fact also big 100,000 times than the present existing generating capacity of All Around The World.The present whole world especially industrially developed country begins to feel shortage of energy, and therefore, people begin to seek help from solar energy, to solve energy crisis.

Solar energy can both infinitely be supplied every day, and quantity is huge.If utilize in big power plant, just reduced greenhouse effect, the expert of some energy expert and environmental protection then thinks, satisfying aspect mankind's energy demand from now on, the thermal impact of solar energy is more much smaller than the thermal impact of any other substitute.As a kind of free from environmental pollution, inexhaustible again new forms of energy, it is ubiquitous.Especially aspect electric power confession power, there is the expert to think that solar power generation accounts for 20% the most at last in supply of electric power.

Solar energy is a kind of radiant energy, and solar power generation means and sunlight will be directly changed into electric energy that it must just can be converted into electric energy by means of energy converter.The process that luminous energy is directly changed into electric energy exactly should be photovoltaic effect.Need be by other any mechanical part, the energy in the light is obtained by the electronics of semiconductor device, so just produced electric energy.This transform light energy being become the energy converter of electric energy, is exactly solar cell.Also allomeric pipe is the same for solar cell, is made up of semiconductor.Its main material is a silicon, and some other alloys are also arranged.Be used to make the HIGH-PURITY SILICON of solar cell, make through special purification processes.As long as solar cell is subjected to the irradiation of sunlight or light, just can change luminous energy into electric energy, make electric current flow to the opposing party from a side, generally just can send 10～20% the electricity that is equivalent to the luminous energy that receives.In general, light is strong more, and the electric energy of generation is just many more.In order to make solar panel reduce the light reflection to greatest extent, change luminous energy into electric energy, generally on it, all cover with the film that one deck can prevent the light reflection, make the surface of solar panels be purple.The basis of its operation principle is the photovoltaic effect of semiconductor PN.So-called photovoltaic effect is exactly when object is subjected to illumination, and the interior CHARGE DISTRIBUTION state of object changes and produces a kind of effect of electromotive force and electric current.When sunlight or the semi-conductive PN junction of other rayed, voltage (being called photovoltage) will appear on the both sides of PN junction.This phenomenon is exactly famous photovoltaic effect.Make the PN junction short circuit, will produce electric current.

The solar energy equipment, particularly some middle-size and small-size utility units that uses is that the sunlight dash receiver is fixed an angle mostly now, can not change the angle of sensitive surface plate along with the rotation of the sun, so the time period over against the sun is subjected to light intensity, it is few to absorb solar energy.Some comparatively large-scale and solar energy equipments relative complex also are equipped with some tracking means, and still, they are more complicated mostly, and making and operating cost are very high, thereby can not extensively use at large.Therefore, need proposition a kind of simple in structure, making and operating cost are low, and the tracking means that working service is convenient, flexible improves the utilization ratio of solar energy, and makes the utilization of solar energy more extensive, more efficient.

The utility model content

The utility model purpose is to provide a kind of solar energy heat collector, in order to the low problem of utilization ratio of the solar energy that overcomes existing photovoltaic panel.

To achieve these goals, the utility model provides a kind of solar energy heat collector, comprising: gatherer, comprise a support frame, and this support frame is provided with a plurality of magnifier module, and each described magnifier module all is arranged on the whirligig; Receiver, described receiver is fixed in the top of gatherer by a structural framing, and in order to receive the sunlight that gatherer is assembled, described receiver is a solar energy photovoltaic panel.

Optionally, described solar energy heat collector also comprises a rotating shaft, and described rotating shaft links to each other with described gatherer.

Optionally, described solar energy heat collector also comprises a base, and described gatherer is fixed on the described base by described rotating shaft.

Compared with prior art, the utility model solar energy heat collector is simple in structure, and making and operating cost are low, and working service is convenient, flexible, has improved the utilization ratio of solar energy on the whole, and makes the utilization of solar energy more extensive.
