The specific embodiment
Fig. 1 has schematically shown the solar concentrator that is depicted as curved mirror 4 and the shade 2 between all solar receivers as is known in the art 6 of being arranged on of the present invention.Curved mirror 4 is a cone-shaped solar beam 8 with focus solar rays, and solar receiver 6 roughly is positioned at the summit of this taper, thereby receives sunbeam 8.The heat of utilizing sunbeam 8 in solar receiver 6, to produce as is known in the art in several ways.
In Fig. 1, shade 2 is depicted as and is shown in an open position, and at this open position, all sunbeams pass through shade, and are received by solar receiver 6.Fig. 2 has schematically shown the operation of the embodiment of shade 2, and this shade 2 utilizes a plurality of movable shadow shields to stop sunbeam 8, and prevents that the changing unit of sunbeam 8 from reaching solar receiver 6.Fig. 2 shows the shade 2 that is in the part closing position, and only some sunbeam 8 is received by solar receiver 6.
The embodiment of shade 2 has been shown among Fig. 4 to Fig. 8, and the embodiment of this shade 2 controls the solar energy that solar receiver 6 receives quite equably.Shadow shield 10 is installed on the shutter frame 12 pivotally in an one bight, and limits medium pore 14.Shadow shield 10 also is pivotally connected on the photochopper ring 16 by connecting rod 20 at its another place, bight, and this photochopper ring 16 rotates with respect to shutter frame in response to the rotation of drive motors 18.Thereby shadow shield 6 can be pivoted to roughly closed fully position from the open position of Figure 4 and 5, part closing position by Fig. 6 and the more sufficiently closed position by Fig. 7.
Thereby can see that when shadow shield 6 moves to closing position from open position, the changing unit of sunbeam 8 will be blocked, and be prevented from reaching solar receiver 6.Therefore can open or closed shadow shield 10 by activated drive motor 18, thereby the heat energy that solar receiver 6 is received also thereby to its temperature carries out meticulous control.That if can see is such, and different with camera shutter is that shadow shield 10 is not overlapping.Sunbeam 8 can pass through between the edge of shadow shield 10, and can be by the center of medium pore 14.Fig. 7 show shade 2 towards curved mirror 4 front portions, and protective plate 21 is installed so as the protection chopping mechanism.Thereby, the embodiment that illustrates covers cone-shaped solar beam 8 from all sides of cone-shaped solar beam 8 simultaneously, thereby the remainder that is received by solar receiver 6 of sunbeam 8 roughly is evenly distributed on the surface of solar receiver 6, causes receiver uniform heating roughly.
Although the concrete layout that illustrates is simple and convenient, and cause even heating to solar receiver 6, but can be susceptible to other layout, shift out the purpose that sunbeam 8 stops the reception of solar receiver 6 thereby also will reach shadow shield 10 moved on in the sunbeam 8 and with shadow shield 10.Near each side that for example can be by a pair of shadow shield being positioned at sunbeam 8, and they are moved to together stopping sunbeam 8, or make their motions separately and do not stop sunbeam 8, thereby such shade is set.Therefore, think that other such layout drops in the scope of the present invention.
Fig. 8 has schematically shown the interior cooling tube 22 in the shadow shield 10, and cooling tube 22 is limited to the inside of each shadow shield 10 in this.Shadow shield 10 is quite thick, and in the illustrated embodiment, by from the outward flange of shadow shield 10, boring pair of holes 24 towards the angle of the inner of shadow shield 10, thereby cooling tube 22 is set quite simply.Hole 24 joins near their the inner, thereby forms cooling tube 22, and the cooling fluid that flows to a hole also flows to another hole.Hose barbs 26 is connected on the end of exposing in hole 24, so that cooling tube 22 is connected on the cooling fluid source 28.Cooling fluid such as water monoethylene glycol mixture, air etc. passes through cooling tube 22 from cooling fluid source 28 circulations.
The size in hole 24 and position are defined as making them to pass through near the surface of shadow shield 10 very much, thereby draw heat from this surface fast.Shadow shield material good by thermal conductivity and that also stand to be exposed to natural environment is made.Aluminium is provided for the good material of shadow shield 10, but also can use the other materials such as copper.The front surface towards curved mirror 4 of shadow shield 10 can also polish, and with reflection sunbeam 8, make to absorb the less heat that must be taken away by cooling fluid.
And, being positioned to as depicted in figs. 1 and 2 under the very close situation of solar receiver 6 at shade 2, shadow shield 10 can be insulation or reflexive at it on the rear surface of solar receiver 6.So, during cloudy or at night, can closed shadow shield 10, thus heat is retained in the solar receiver 6, thereby rather than by medium pore 14 radiation forfeiture.
Fig. 9 has schematically shown and be suitable for the replacement shade 102 that uses as Fig. 3 and 10.Shade 102 comprises annular shutter plate 110.By mode similar to the above, will in this annular shutter plate 110, limit one or more in cooling tube 122, described one or more in cooling tubes 122 be connected to cooling fluid source.Annular shutter plate 110 is made by Heat Conduction Material equally, thereby is convenient to remove heat by means of circulation by the cooling fluid of interior cooling tube 122.
As shown in figure 10, when annular shutter plate 110 was positioned at position A, close solar receiver 6, all sight bundles 8 all passed through medium pore 114, and arrived solar receiver 6.Annular shutter plate 110 is installed on the track etc., thus driver can make shadow shield 110 towards or leave solar receiver 6 motions.When annular shutter plate 110 was left solar receiver 6 motions, the outside of cone-shaped solar beam 8 was stopped by annular shutter plate 110.At position B, the sub-fraction of sunbeam 8 is blocked, and at position C, sunbeam 8 very large parts are blocked.
Although the concrete layout that illustrates is simple and convenient, but can be susceptible to other layout, also will reach shadow shield 10,110 moved on in the sunbeam 8 and with shadow shield 10,110 and shift out sunbeam 8, thereby therefore the purpose that stops the reception of solar receiver 6 thinks that other such layout drops in the scope of the present invention.
Therefore, thinking above only is the explanation of the principles of the present invention description.In addition; because those skilled in that art will expect a large amount of variations and modification easily; thereby the present invention is not defined as the precision architecture and the operation that illustrate with describe; therefore, all the suitable variations that can take in structure or operation or modification all will fall within the claimed scope of the present invention.
