Abstract
The invention discloses an integrally packaged type solar heat collector with combined curved surface for light collection and vacuum tube for heat collection, belonging to the technical fields of solar light collection and medium and high temperature solar heat collection. The solar heat collector of the invention comprises a combined curved surface light collector, a vacuum tube heat collector, an adjustable tracker, a packaging shell and the like. After the sun light enters the combined curved surface light collector through a transparent glass cover plate, the sun light is reflected through an inner surface of the combined curved surface light collector and collected onto the vacuum tube heat collector, the vacuum tube heat collector absorbs the sun light to generate high-temperature heat energy, and the heat energy is conducted and transmitted to users by a heat conducting working medium in the vacuum tube heat collector. The invention can collect the sun light with low energy flow density after being reflected by a plurality of curved surfaces on the vacuum tube heat collector, thus the heat conducting working medium in the vacuum tube can be quickly heated to form high-temperature heat energy. The manually adjusted tracker can adjust the orientation of the combined curved surface light collector to track the sun, thereby enabling the heat collector to keep in the optimal sun light collecting state. The invention is especially suitable for use in high-latitude areas and in winter when the solar altitude is smaller.
Description
Affiliated technical field
The invention belongs to Salar light-gathering and solar energy high temperature heat utilization technology field.Specifically a kind of concentrator of particular design that utilizes combines the composition new structure with vacuum tube collector, and this new structure carried out overall package, make it to become the solar thermal collector parts of a standard, thereby realize the sunshine high-density aggregation and produce the helioplant of high temperature heat.
Background technology
In the middle high-temp solar heat collector of promoting the use of at present, mainly contain focusing of paraboloid of revolution pip and two-dimentional parabola groove reflected ray and focus on (also claiming slot-type optical collector) two classes.The former advantage is the heat-collecting temperature height, and shortcoming is that unit scale is limited, complex process.The latter's advantage is to install on a large scale, and technology is simple relatively, and shortcoming is that light is difficult to be focused on very little zone, and heat-collecting temperature is relatively low.The light harvesting principle of this two classes device all be by parabolic reflector with the sunshine retrodirective reflection to paraboloidal focus place, collect the generation high temperature heat through solar receiver then.But high temperature heat collector all can not be utilized by family because the tracking accuracy of manufacturing cost height, requirement is high in miniaturization in these two kinds of solar energy.
On the other hand, at present people adopt at most solar vacuum tube type heat collector and flat-plate collector, owing to low costly be used huge numbers of families.But because electron tubes type heat collector and flat-plate collector do not have light-focusing function, so the solar energy that is received on the unit are heat collector is very limited, has limited its temperature increase, so generally they can only be used for producing low temperature heat energy.Arrive when winter, when environment temperature was very low, these two kinds of heat collectors were difficult to produce the heat energy that closes the symbol requirement.But also may be because the water freezing in the pipe, thereby the bad pipeline that expands be destroyed whole system.
The present invention has made full use of composite surface concentrator, vacuum tube collector and flat-plate collector advantage separately, and it is combined together, and forms a kind of brand new solar energy heat collector.Because the composite surface concentrator need follow the tracks of the sun, so we have designed simple and easy adjustable tracking system, make it to remain the best collection status to sunshine.This quantity of installing employed vacuum tube collector significantly reduces, and structure is compact more, and is lower to the specification requirement of solar tracking system, is particularly suitable for using less winter at high latitude area and sun altitude.
Summary of the invention
The directional light that the present invention utilizes the composite surface concentrator will hang down energy-flux density pools line source, and the ray cast that major part is converged is to vacuum tube collector, and by vacuum tube collector luminous energy is converted into middle high temperature heat.Because the heat energy that single vacuum tube collector is collected is still limited, therefore many vacuum tube collector parallel connections are fused, and overall package makes it to have functions such as attractive in appearance, heat insulation and dustproof in a shell body.This device can be applied under the low temperature environment collection to solar energy, and high temperature heat in producing.
The technical solution adopted for the present invention to solve the technical problems is: the condensing evacuated pipe thermal-arrest of a kind of composite surface integrally packaged type solar heat collector comprises at least one composite surface concentrator, at least one vacuum tube collector, at least one hand adjustment tracker, connecting rod, package casing;
Wherein each composite surface concentrator is made of two one-level parabolic condensers, two two-level plane speculums, bottom land parabolic condenser or semi-cylindrical concentrator, and wherein two one-level parabolic condensers link to each other with the bottom land parabolic condenser by two two-level plane speculums respectively;
Perhaps, each composite surface concentrator is made of two one-level parabolic condensers, a secondary parabolic condenser, and two one-level parabolic condensers link to each other with the secondary parabolic condenser respectively; The reflective surface of each concentrator is towards vacuum tube collector;
Vacuum tube collector uniformly-spaced secured in parallel keeps certain heat-dissipating distance in package casing and with the base plate of package casing;
The composite surface concentrator flexibly connects by connector and vacuum tube collector, and the composite surface concentrator can be rotated around vacuum tube collector;
The hand adjustment tracker is fixed on the connecting rod top, and connecting rod flexibly connects with the bottom of all composite surface concentrators successively;
During rotation hand adjustment tracker, to spur connecting rod and move up and down, thereby pulling composite surface concentrator is the axle rotation with the vacuum tube collector, thereby realize control a plurality of composite surface concentrator angles, realize the composite surface concentrator towards doing regular adjustment, follow the tracks of the sun.
Glass cover-plate is stamped in the front of the package casing of the condensing evacuated pipe thermal-arrest of described composite surface integrally packaged type solar heat collector.
The invention has the beneficial effects as follows, the sunshine that hangs down energy-flux density can be pooled the sunshine of high fluence density wire, and the ray cast that major part is converged is converted into middle high temperature heat by vacuum tube collector with luminous energy to vacuum tube collector.The vacuum tube collector quantity that needs on this unit's of making heat collector area to use reduces, thereby reduced the quality of vacuum tube collector internal heat transfer working medium, and then reduced the thermal inertia of whole system, make the intensification of system rapider, be particularly suitable for the situation that the sunshine-duration in winter is short and environment temperature is low and use.In addition, since utilize hand adjustment tracker among the present invention can adjust the composite surface concentrator towards following the tracks of the sun, make the best collection status of heat collector maintenance to sunshine, specification requirement to solar tracking system is lower, is particularly suitable for using less winter at high latitude area and sun altitude.
