Figure 22 is the view of another embodiment of control panel shown in Figure 21; Implement approach of the present invention:

With reference to accompanying drawing, a kind of solar energy radiator, generally speaking by digital 1 indication, according to the present invention, by a control panel 2, main purpose of design is: a) produce and cover shade; B) collect by the sun portion of energy that should be protected of radiation earthward: c) produce the air-flow that constantly raises; D) need not use extra energy just in atmosphere, to discharge described energy passively.

Control panel described in Fig. 1 needs erecting device, this device is made up of two conducting strips 31 and 32, they are vertical mutually, so that fully toward each other, it is separated by two position marginating compartment devices 41 and 42, these two walls separate at two conducting strips 31 and 32, and are bound up at its edge termination place, thereby have formed wall 50.Like this, they just can form a firm support frame, by legend shown in Fig. 1, this framework is by two poles 81 and 82, and itself and ground form right angle are to support with the perpendicular angle of described conducting strip, not only determining distance with ground, allow air to enter wall 50, and the direction of air-flow is rotated with the direction of sun day's activities, perhaps with another direction more easily.

Especially, two conducting strips 31 and 32, for example, this thin conducting strip can be made by metal or aluminum alloy materials, also can be made by other suitable Heat Conduction Material, its shape can need not to be rule, but must coincide mutually, its size and thickness can be regulated and change at any time, to guarantee the mechanical stability of control panel 2, also make described control panel can bear pressure, such as wind such as air motion.

Fig. 2 explains the operational effect of the solar energy radiator that control panel has been installed, and the device that is made of two conducting strips is housed on this control panel, the direction of motion that on behalf of the air-flow in the thermal insulation layer 50, conducting strip 31 and 32 internal arrows indications rise.Control panel produces covers the right side that shady part is positioned at conducting strip 32, and Fig. 2 does not show that air-flow rises to the situation on conducting strip 31 left sides, because compare with the air-flow of thermal insulation layer 50 inside, it belongs to inferior air-flow, does not produce identical influence.

That shown in Figure 3 is the operational effect figure that the solar energy radiator of control panel is housed.Have one on this control panel by two conducting strips 31 and 32 and devices that heat shield 16 is formed.This heat shield is inserted in the middle of two conducting strips, its objective is, contacts with the control panel air outside by making conducting strip 32, reduces the consumption of heat energy at the air-flow of thermal insulation layer 51 internal circulations.

As shown in Figure 4, contain the dynamics that the conducting strip of strengthening border 6 can increase control panel 2, this is strengthened the border and links to each other with the part at conducting strip 30 edges at least, thereby can strengthen its structure, also can be engaged 7 reinforcements, perhaps link to each other with the part of conducting strip 30 at least, perhaps carry out the advantage combination with two reinforcements.

Have the conducting strip 30 of corrugated horizontal surface by use, the mechanical forces of control panel 2 strengthens to some extent, as shown in figure 10.

As Figure 12 and 13 illustrated embodiments, from outward appearance last year, control panel 2 is by pole, optical cable, suspension hook, and other enclosure group becomes, wherein conducting strip 31 and 32 thin slices by metal or other Heat Conduction Material constitute, as previously mentioned, constitute by the thin slice of heat conduction fabric 121 and 122, its upper end with preceding two top optical cables 13 link to each other, its bottom end links to each other with second pair of top optical cable 14, and this optical cable links to each other with support frame 15, and support frame is made up of two poles and corresponding support, is used for supporting and extension pole.At some in particular cases, heat conduction sheets of fabric 121 and 122 shown in Figure 12 and 13, can combine together with support frame 15, by using fixed part or interval both is installed in on one side, and does not need to embed framework.These do not have demonstration in the accompanying drawings.

Figure 14 shown in 15 and 16, supports not show, and is the same with 41,42 wall, higher than conducting strip.

What Figure 17 showed is another kind of situation, and what be control panel 2 installations is two highly different conducting strips 31 and 32, so just guarantees that air-flow under any circumstance can both enter wall 50, also as shown in the drawing.Conducting strip might be installed on the higher on the ground height, thereby two conducting strips are supported mutually, constitute the structure that the alter ego supports.

The view of control panel 2 shown in Figure 180, the incidental device of this control panel is made up of a conducting strip 31 and two support bars 81 and 82.

Figure 19 shows is the operational effect figure of solar energy radiator that comprises control panel 2 devices of a conducting strip 30.Owing to lack second conducting strip, the air-flow of two bursts of risings will be more similar, as vertical arrows indication among Figure 19.The effect that Figure 19 was produced when not showing two strands of ascending airs and air-flow around control panel contacting is because detail will describe in detail in Figure 20.

That Figure 20 shows is the running figure that the solar energy radiator of control panel is housed, and this control panel has the device of a conducting strip 30 and two transparent laminas 21 and 22.This design more can make by the collected most of heat energy of the conducting strip that air-flow surrounded around two walls 51 and 52 and all put together, thereby improves the efficient of control panel 2 greatly.

Figure 21 is the view of control panel, and this control panel comprises the fabric device of being made by Heat Conduction Material.The side of this fabric is made up of the support frame of optical cable and corresponding accessory thereof, and the latter does not show in the accompanying drawings.Select sample as another kind, this fabric can by other annexes directly and support bar 15 be installed together.The heat conduction fabric can be supported by metallic laminas.

Figure 22 is the view of control panel among Figure 21, and its difference is that this device is made up of a conducting strip or heat-conducting layer, one side it is from the another side that leads to supporting control panel of support bar 15.

The efficient of each control panel 2 can effectively improve by several improved procedures,, first kind is exactly that these wall is trapezoidal, just can make wall 50 be the pyramidal shape on the top of pruning by use marginating compartment layer.Conducting strip 31 and 32 joint stretch to the summit, thereby make the air-flow that enters from wall 50 low sides obtain extruding, in the ascending motion process of air-flow, form bigger pressure with conducting strip 31 and 32 surfaces, thus the accelerated heat exchange.

The target of another kind of solution is, by conducting strip 31 and 32 energy of being drawn.Promptly in the appearance or the inside of described conducting strip, perhaps light-absorption layer is installed on both sides, and this light-absorption layer can be made with one deck coating dark color or unglazed thin or that one deck is thicker.

Also have the target of a solution to be, improve the endergonic efficient of control panel that has device, this device just comprises heat-conducting layer and thermal insulation layer, comprise hinge a lot of levels or vertical, its be in gravity axis position easily, or the support bar machinery that is in horizontal center of gravity and vertical center of gravity position links to each other, or the device of universal interface, its purpose is the direction of modifier and conducting strip, makes it along with position that daytime, the sun moved and change direction.In order further to improve the stationkeeping ability of described device, hinge and aforesaid other annexes may be replaced by electronic mechanism parts many automations or sequencing.Like this, in order further to help described long-distance positioning function, these hinges or annex just can link to each other with described positioner from function.

Make each control panel 2 not be subjected to the restriction of nature electric power function, can use, or use cathodic protection, or both have both at the same time such as the light protection, or the another one solution.

From visual angle, the environmental influence of solar energy radiator 1 can be reduced by each control panel 2 is covered the last layer allochroic paint, this coating is very similar to the color of surrounding environment, perhaps on the angle of environment, the material of each control panel 2 is all selected recyclable material for use, as rod or sheet metal.

Another embodiment of control panel 2, shown in accompanying drawing 14,15 and 16, be conducting strip 31 and 32 is done camber or columniform.Like this, each control panel 2 all is made up of two conducting strips 31 and 32, and the radius difference of their radians, but coaxial, separated by two marginating compartment layers 41 and 42, wall is between two conducting strips 31 and 32, link to each other at edge termination, perhaps the opposite position of diameter, so just energy internal interval layer 50, thereby the air-flow that solar radiation is formed passes from the centre, does not also have the diagrammatic sketch that supports in the accompanying drawing.These embodiment; because its unique shape; can mount and dismount arbitrarily; especially the plant for the special plantation of protection particular locality has crucial effect; as some light green plant; perhaps lack the zone of irrigating at some, perhaps inconvenience takes the area of other safeguard measure especially helpful.In the time of necessary, can also opaque conducting strip 30 be installed, make it parallel to the ground, like this,, can also use optical cable and indivedual the support and annex for the air-flow that makes the heat that forms in the bottom is upward through the countless eyes of conducting strip in a large amount of upright positions.

Solar energy radiator 1, as Fig. 6,7,8, and shown in 9, its structure is, is made up of a plurality of control panels 2, the quantity of control panel can change according to the size of the land area that will protect.Solar energy radiator can arrange control panel 2 fully by horizontal distribution, horizontal distribution, be for allow conducting strip 31 and 32 and ground maintain a certain distance, and this distance is variable from several centimetres to several meters.(said herein " variable " is not that conducting strip can at will move or move down) so just can be reserved enough spaces and make at interval that 50 li air obtains the nature circulation.Each row is made up of control panel 2, can be placed side by side, so just can form a long row control panel, it must obtain rational interval, towards east or westwards, perhaps regulate according to obtained effect, also can be as shown in Fig. 7 or Fig. 9, keep flat or a shaped form arranged a little.Especially, so just can avoid the time the hottest in the middle of one day near control panel, to produce covering that shade brings influences each other, also can avoid these influences by day in early time or later.

Consider by unrestriced explanation example, equatorial line and with the control panel of two conducting strips, these several rows are made up of control panel 2, its location, each control panel 2 all has conducting strip 31 towards in the east, be convenient to collect in the morning the sunshine of maximum, conducting strip 32 is towards the west, is convenient to shine upon in the afternoon collect sunshine the strongest the time.Vice versa.Certainly, only have the control panel of a conducting strip, control panel can be adorned towards east or towards Xi'an respectively.The installation location of certain control panel 2 is depended on the geographic orientation that will protect soil also can change according to the path of season or sun day's activities or the effect that reaches.

According to Figure 19, solar light irradiation makes its heating on conducting strip 30; This conducting strip is made by metal or other suitable Heat Conduction Material.The location of conducting strip also is in the morning or collect the solar radiation of maximum afternoon.Sunray produces a large amount of photosensitive heats, and this conducting strip meeting is cools down owing to the motion of air-flow, as detailed demonstration is arranged among Figure 19.Because lower relative density, thermal current rises.In the first step of production control panel, can produce one and cover shady and two strands of thermal currents, as detail display among Fig. 9.Operation principles is, can be by second Heat Conduction Material of detail display in the installation diagram 1,2 and 17, and the efficient that has the control panel of monolithic Heat Conduction Material can improve greatly.Wall 50 cools off the air-flow in the boundary naturally, and described air-flow is from around the control panel.Another conducting strip flows air-flow in the middle of interval 50, thereby makes the heat energy of described air-flow avoid being diffused in the middle of the control panel ambient air.The another kind of possibility that improves the control panel thermal efficiency is, two transparent conducting strips of depositing side by side are installed, and as shown in figure 20, described transparent conducting strip is made by only material.Through this change, the air-flow that produces in wall 51 and 52 according to Figure 20, does not distribute its heat energy with the control panel ambient air.Like this, two walls 51 and 52 derivation part as shown in figure 20, might obtain two strands of air-flows in the control panel, and it is than the air-flow with the conducting strip edge of the control panel of transparent laminas is not warmmer.The scheme of other raising control panel efficient as previously mentioned.All control panels all produce hot-air.All hot air-flows all move from the ground naturally, take them the height of the heat energy that they accumulate to, thereby contact with the conducting strip of control panel.All thermal currents all move on to its thermal current the higher level the inside of atmosphere at least in part and have gone.

Having the control panel of one or two wall, conducting strip is installed in the place apart from the appropriate location, ground, so just air is entered from lower wall.Conducting strip and other parts all are installed in apart from the place of ground more than one meter, and it highly depends on the effect of generation.

When control panel 2 has blocked ground from the direction that shines upon, produced shadow zone, the thermal current of rising, except attracting colder air from contiguous shadow zone, the heat that also disperses conducting strip and gathered makes it leave from ground.

Under any circumstance, solar energy radiator 1 does not gather strength, and cools off naturally at night, does not produce pollution, does not need extra energy to operate yet.

In some special example application, it is in order to reduce the influence of solar radiation that solar energy radiator is installed, because solar radiation in some cases can be very strong, as shown in figure 11, in the overcover in greenhouse 150, or in snowfield, or, can stop or postpone the progress of its thawing at the surface installation solar energy radiator 1 that ice and snow covers.

If think that solar energy radiator 1 is not necessary, perhaps think extreme necessity, that just might be removed radiator at any time, perhaps possible words, with list or other reflectorized materials radiator is covered, its effect of so just neutralizing is perhaps just rolled the conducting strip 31 and 32 of control panel 2, as phenolphthalein tablet is by list or other elastomeric material systems, can with other compatible system neutralization.

In the middle of the practice; we also find; can realize target fully according to solar energy radiator of the present invention; because; although the present invention is very simple in design; cost is also lower; thereby make soil might reduce the influence that over-exposure produces as far as possible under solar radiation, also might regulate the temperature of environment, reduce the temperature in its soil of protecting; and the temperature of radiator periphery; so just can slow down the speed of mountain area or arctic regions ice dissolution, can also increase temperature in some cases, especially at night; temperature increases in the middle of air, also such as in arid or class desert area.

In addition; the too rising sun of the present invention can also not need consumed energy just to slow down the influence of drought period by radiator; also can be in place that its is installed to some emphasis ground segment protect shade for a few hours; thereby reduce the evaporation of moisture; slow down the dewatering speed of plant; or fall the evaporation of few surface humidity, thereby form contrast with the ground of arid.

Solar energy radiator can repeatedly be changed and be out of shape, the each change all in appendix in the claim scope.All details can further replace with other technical equivalences parts.

In the middle of practice, perhaps compatible mutually as long as be applicable to concrete purposes with concrete shape and size, can adopt any material with prior art as required, make this solar energy radiation and clamor.

The priority that requires in disclosures in Italian patent application VI2005A000269 and the described patent application of patent No. VI2005A000293 is referring to data.
