Description
Technical field
The utility model belongs to the heat exchange element technical field, relates to a kind of solar thermal collector, particularly a kind of plate solar collector.
Background technology
China is maximum in the world coal production state and country of consumption, and coal accounts for 76% of commercial energy consumption structure, has become the main source of China's atmosphere pollution.Tap a new source of energy energetically and will become the important measures of minimizing environmental pollution with the utilization technology of regenerative resource.Solar utilization technique reaches its maturity, and especially aspect the exploitation of solar thermal collector, all there is investment in special items in many countries in research.At present in China; Solar thermal collector is widely used in being applicable to the hot water supply of projects such as hotel, school, army, hospital, industrial enterprise, residential houses, natatorium, also has fields such as solar heating, solar energy warm water cultivation, agricultural greenhouse, industrialness oven dry and other industrial or agricultural also to be applied.
In order to improve solar energy utilization rate, people have carried out various exploitations and improvement to solar thermal collector.A kind of plate type solar concentrating collector [ZL patent No. 02217701.9 like State Intellectual Property Office of the People's Republic of China's announcement; Granted publication CN2557882Y]; It is characterized in that the said outer surface that has the collector metal pipe of fin is provided with the structure of three wing fins at least; To increase endotherm area; The cross section of the condenser groove concave curved surface of said concentrator is the structure of compound (parabolic) concave curved surface of leading with the parabola for what is made up of circular arc, parabola, involute and circular arc successively, so that sunray is converged on the thermal-collecting tube that is positioned at along.The utility model heat collector has quick heating, and running temperature is high in the optically focused tank; Thermal insulation is good, and the thermal efficiency is high, and its average daily efficient can reach about 60%; Manufacturing process is simple, assembling easily, needn't the situation of adapted sun tracker under; Can both incident sunlight be converged on the thermal-collecting tube (absorber) throughout the year, to obtain hot water even boiling water.But the collector metal pipe conversion ratio of the structure of this three or three above wing fins is not high, and average daily efficient is about 60%.
Summary of the invention
The purpose of the utility model is to existing technical problem, has proposed the high plate solar collector of a kind of conversion ratio.
The purpose of the utility model can realize through following technical proposal: a kind of plate solar collector; Comprise a base; Has cavity in this base along horizontal spreading; It is characterized in that said cavity place is provided with the superconducting pipe that is used to conduct heat in a tubular form, the surface of described cavity also is provided with optically focused spare corresponding to the superconducting pipe place.
Superconducting pipe is installed in the cavity of plate solar collector base.Solar light irradiation is on plate solar collector, and a part is directly absorbed by superconducting pipe and changes into heat energy.Remain a unabsorbed part and be radiated at pocket surfaces, because pocket surfaces has optically focused spare, this part sunshine will be reflected and focus on the superconducting pipe, changed into heat energy by superconducting pipe again, thereby improve the photo-thermal transformation efficiency of this plate solar collector.
In above-mentioned plate solar collector, described superconducting pipe is made up of to the vertical arm that is connected above that along charge shaft with some a person in charge, and above-mentioned optically focused spare is corresponding to every arm place.Because arm is connected on the person in charge, the heat at each root arm place can be passed to smoothly be responsible for through it and goes up or the heat on the person in charge is passed on the every arm smoothly.Each arm all has its corresponding optically focused spare, absorbs on the arm of optically focused spare with unabsorbed sunshine reflected back correspondence again.
In above-mentioned plate solar collector, described optically focused spare has some curved condenser grooves, and the quantity of condenser groove is identical with above-mentioned arm quantity and the position is corresponding.The condenser groove manufacturing process is simple, and assembling under needn't the situation of adapted sun tracker, can both converge to incident sunlight on the superconducting pipe easily throughout the year.The condenser groove of arc can be with solar light focusing to a focus of all directions, and the position of adjusting arm in advance all focuses on the corresponding separately arm focus of each condenser groove.
In above-mentioned plate solar collector, described optically focused spare is processed by reflectorized material.Reflectorized material utilizes the microprism principle of reflection, has the reflecting rate height, and weatherability is strong, the premium properties that reflective angle is big.
In above-mentioned plate solar collector, described optically focused spare is reflective cloth or reflective lattice or reflective membrane or lattice.
In above-mentioned plate solar collector, described optically focused spare is the solar panel with some curved condenser grooves, and on solar panel, has reflectorised paint.Reflectorised paint has the reflecting rate height, can prevent the irradiation of ultraviolet light wave, prevents that the color desalination from peeling off, and can resist extremely strong salt fog, anti acid alkali performance ability.Curved solar panel is sprayed reflectorised paint equably just can use, such condenser groove is made simple and fast.
In above-mentioned plate solar collector, be provided with heat-insulation layer between described optically focused spare and the base.Heat transmission between effectively isolated base of heat-insulation layer and the optically focused spare makes the interior heat of cavity be difficult for running off, and improves heat collector to solar energy utilization rate.
In above-mentioned plate solar collector, described heat-insulation layer material is a polyurethane.Polyurethane has heat-proof quality preferably, be at present in all insulation materials thermal conductivity factor minimum, and freeze thawing resistance, non-deformability are strong, not easy to crack, durable in use.
In above-mentioned plate solar collector, described heat-insulation layer material is a foamed plastics.The foamed plastics thermal conductivity is low, and processing and forming is convenient, and material price is low.
In above-mentioned plate solar collector, described heat-insulation layer material is the mineral wool goods.
Compared with prior art, this plate solar collector has the following advantages:
