The specific embodiment
For further setting forth the utility model is to reach technological means and the effect that predetermined goal of the invention is taked, below in conjunction with accompanying drawing and preferred embodiment, to according to its specific embodiment of flute profile solar thermal collector, structure, feature and the effect thereof that the utility model proposes, describe in detail as after.
72 pages of introductions of junior physics according to the printing of People's Education Publishing House's in June, 2004 the 4th: concave mirror can be focused at its parallel rays of directive a bit, and the people have invented solar cooker thus.The reflector of solar cooker converges to sunray on the kitchen range mouth position, makes apparatus such as being placed on the locational kettle of kitchen range mouth bear the sunlight after the convergence and obtains heating and be used to heat up water and cook not only fuel savings but also sanitation and hygiene.But the reflector of solar cooker can only form an isolated focus, and these isolated focuses are difficult to the exploitation of large scale system.Form isolated focus, defective that purposes is single in order to solve solar cooker, expand the scope of utilizing of solar energy, the utility model discloses a kind of flute profile solar thermal collector.Its reflector is different from common solar cooker as a bite pot spherical structure reflector, it is more as a part of founding the petrol drum of riving, be that the sheet bar that a block length is square is bent inwardly into certain radian to two corresponding long limits, then each bar formation line parallel with long limit all is straight line on the thin plate, and it all is camber line (vice versa) that each bar parallel with minor face constitutes line.When curving the radian of regulation, then reflector is converged to one to sunray and is suspended in reflector top (or in groove) the elongated straight linear focus corresponding and parallel with reflector, as long as heat pipe is fixed on the focal position by fixed bar, make reflector break away from ground with the stent support heat pipe, just can become a flute profile solar thermal collector, then reflector converges to the sunray of reflection on the heat pipe, heat pipe is absorbed and the conduction heat.The radian of reflector and size can change arbitrarily according to user's installation requirement and result of use, but change in any case, and elongated heat pipe by chance is placed on the elongated linear focus of sunlight that reflector is assembled.For improving the utilization rate of sunlight, the parallel sunray of injecting its inner surface can be reflexed to principle on its focal position according to parabola on the physics, we can be according to parabolic equation, thickly be the horizontal ordinate that draws on the iron plate of 1mm at one, determined the position of focus, calculated the concrete numerical value of some coordinate points, be punched in point and go out small rut on the iron plate coordinate points position, with the scriber line small rut is coupled together, the line that obtains after the connection is parabola.Along parabola Iron shears is cut into two, wherein one is parabolical inner surface, and another piece is parabolical outer surface.The iron plate that to contain the parabola inner surface shears from distance parabola 3cm distance, become one and widely be the parabolical lath of 3cm, be about 3cm with another width again, thick is that straight iron plate bar about 1mm is by on the inner surface of parabola shaped iron plate bar, press sternly to weld together, just having obtained inner surface is parabola shaped T shape reinforcement.The sheet iron that inner surface is had reflecting coating is riveted together with reinforcement by on 2-3 root reinforcement inner surface, has just obtained the flute profile reflector.Though the reflector cross section that obtains with the method is not real parabola, its effect of assembling sunlight is also fine.If make the cross section of reflector is real parabola shaped, in the time of can on being decorated with parabolical iron plate, shearing parabola, straight iron plate bar and reflector add thickness together under shear more, make smooth reflective sheet iron by after riveted joint on the reinforcement, the radian of inner surface by chance is parabolical radian.
If feel to feel that the method with parabolic equation coordinates computed point bothers, we can determine the radian and the position of reflector with a simple method, and the method can be called the long-focus elliptic method.We know, in one plane diverse location is followed closely two nails, look for one section line of slightly being longer than distance between two nails, the two ends of line are fastened respectively on nail, the direction stretching line and the mobile pencil along the line that are parallel to the plane with the pencil edge, after moving a week, pencil gets back to starting point, we just obtain the figure of an ellipse in the plane, two residing positions of nail are exactly two focuses on the elliptic geometry meaning, the extended line of bifocal and ellipse have two intersection points, distance between two intersection points is exactly oval longest diameter, in position near an oval end focus, work is perpendicular to the line of cut of longest diameter, ellipse is cut into two parts, one section wherein short camber line just can become the radian of reflector, and the focus on what meaning of the pairing youngster of the oval camber line of this section is exactly the center of the focus of this radian sunlight that reflector converges.I find by test of many times, and when the longest diameter of the approaching more ellipse of the distance between the oval bifocal, the reflector optically focused degree of this radian is high more, and just linear extraction regions is narrow more.The ratio of the distance between bifocal and longest diameter is greater than 96%, best near 100% o'clock effect, so the method is called the long-focus elliptic method, method successively, making slot opening with 1 * 2 meter iron plate is 70cm, and length is 2 meters flute profile reflector, can will pool the wide linear focus about Icm that is after the sunlight reflected, even in the winter time, also can produce about 120 ℃ high temperature at the focus place.With the above-mentioned reinforcement of doing earlier, the back on the reinforcement fixedly the method for reflector only be fit to the sheet metal about 0.5mm is made into reflector, if the making material of reinforcement or reflector is thick, we can be with hydraulic machine with materials such as angle bar, band steel, the reflector needed radian that directly bends.If the reflector material after bending is thick not yielding, also can on reflector, adhere to reinforcement, but the cost of manufacture of reflector is increased.Also the reflector that steel plate can be made is as loose tool, materials such as the cement that covering thereon stirs, gypsum, the reinforcement that materials such as band iron are made is embedded in the materials such as cement, gypsum, surperficial within it spraying reflectorised paint or stickup reflective membrane just become reflector after drying, and make the raw-material selection of flute profile solar thermal collector more extensive.Can also make reflector with glass, though the reflector that glass is done is more thick and heavy, fearness is collided with, its long service life, and reflecting effect is that other reflectorized materials are incomparable.In order to adapt to the external environment of not watching season and different regions, the flute profile solar thermal collector is changeable, and its heat pipe can be in along with the difference of reflector spreading angle in the groove of reflector or outside the groove, even contacts with the bottom land summit of reflector.Low for adapting to the winter solar incidence angle, the environment that north wind is many, flute profile solar thermal collector reflector can also be made into the shape of asymmetric single-blade, because the sun in winter can only be raised to that to look up the angle be position about 35 ° in that northern area is the highest, be almost half of summer, so can be placed on roof or the ground by the end with single-blade reflector opening in when assembling, the other end breaks away from ground by the stent support heat pipe, make its angle of inclination can be with 8, the sunray at 9 o'clock converges on the heat pipe, along with the sun raises, it is just passable that dependence sunlight follow-up mechanism drive draught line lifts reflector more than 20 degree angles slightly.Because of its single-blade, also little so the windward side is little to the resistance of wind, also saved the material of a part of making reflector relatively, its reinforcement is asymmetric certainly, fixed bar neither be isometric up and down.
Be further described this use is novel below in conjunction with accompanying drawing:
Fig. 1 is made of support 3, heat pipe 2, anchor ear 4, reflector 1 etc. for this heat collector of structure principle chart of heat pipe external flute profile solar thermal collector.Earlier heat pipe 2 is fixed on the support 3 during assembling, again anchor ear 4 is stuck in heat pipe 2 two ends, then fixed bar 5 is fixed on the anchor ear 4 at reflector 1 both sides and heat pipe 2 two ends, on the anchor ear 4 holding screw is installed, adjust behind reflector 1 light angle screw is fastening, also can transfer and loosen the screw a little, reflector 1 can be rotated around heat pipe 2, light source tracking device is installed for like this reflector 1, make reflector 1 adjust light angle, absorb solar energy to greatest extent according to solar motion track automatic or manual.This reflector 1 is fit to use thick and heavy on-deformable material to make.Do not show bearing and holding screw among the figure, because heat pipe is round, so can rotate slowly when the quality of anchor ear 4 is good around heat pipe 2 yet.
Fig. 2 by the reflector 1 of this heat collector of the built-in flute profile solar thermal collector of heat pipe structure principle chart the elongated focus point of convergence sunlight in reflector 1 groove, so heat pipe is also in reflector 1 groove, groove useable glass plate suitable for reading covers, obturage respectively with side seal board 7 in reflector 1 both sides, insulation also can be done with materials such as polystyrene in reflector 1 back side, use fluid sealant blind, the heat that sunshine produces then can be closed in the system, even there is strong wind also to be not easy to scatter and disappear.Fig. 3 and Fig. 4 are respectively the schematic perspective view of the side seal board of reflector both sides, use the heat collector of side seal board to connect with fixed bar and heat pipe 2.This heat collector is fit to connect with the small-sized shower bath of family.
Fig. 5 is that the spreading angle of combined flute profile solar thermal collector structure principle chart reflector 1 is more little, linear extraction regions is near more when less than the diameter of heat pipe from the distance of reflector 1, can directly be fixed on reflector 1 on the heat pipe 2, heat pipe and reflector be held tightly with anchor ear shown in Figure 6.
Fig. 6 is the interior sheet and the outer plate of anchor ear, and interior sheet is placed on and blocks heat pipe 2 in the reflective board slot, and outer plate is placed on outside the reflector 1 and on the corresponding position of interior sheet, interior sheet and outer plate are fastening with pulling rivet or screw.A slice reflector can use two or more anchor ears as required.
Fig. 7 is the vertical scheme of installations of the many groups of flute profile solar thermal collector, and the various forms of heat collectors of 11 representatives connect the framework of heat pipe 2 earlier according to customer requirements during installation among the figure, after finishing with support 3 supports, on heat pipe reflector is installed successively again.Though install similarly with level, can make the bigger pressure differential of water generates after the heating and flow inflow attemperater 8.9 is cold water supply pipeline among the figure, and 10 are the outflow of the water after heating pipeline.To strengthen the distance between every row's heat collector 11 during installation, in order to avoid keep the sun off mutually.
Fig. 8 is many groups of horizontal scheme of installations of flute profile solar thermal collector, determine the specification and the quantity of reflector according to client's needs, determine the length and the trend of framework substantially of heat pipe thus, preferably draw a simple general assembly drawing earlier, heat pipe is connected with threeway, pipe collar, the first-class pipe fitting of loose joint according to drawing.Consider the specification of cost and reflector, the heat pipe diameter is thin more good more, the galvanizing pipe of the most handy 4 minutes or 6 minutes, water transmits media as heat, after all water pipes connect, can on the heat pipe 2 of reflector 1 present position, brush the heat-resisting antirusting paint of black (also preceding brush can be installed), determine the position of support 3 and connect according to the weight capacity of the specification of reflector and water pipe with water pipe, support 3 is just liftoff with the water pipe frame supported of integral body, will adjust the water pipe gradient according to water (flow) direction in peace support 3 processes, arrow is depicted as liquid flow direction in the pipeline among the figure.As shown in the figure, water pipe will be lower than water pipe between E, the G at 2 between 2 of A, the B, and the C point will be lower than the B point, and the D point will be lower than the C point, reflector 1 usefulness fixed bar 5 is hung over successively to be subjected on the hot-water line thereafter.Current advance direction and are lower than the water pipe that flows out direction and can hang reflector among the figure, so, reflector is sunlight cold water in the heating tube on water pipe, just can move to the high-end of water pipe after cold water heats gradually, enter attemperater 8 by the E point, the cold water of attemperater 8 lower floors can add in the heating system of being made up of reflector 1 by water pipe again, as long as it is sunny, water temperatures in the attemperater 8 can be more and more higher, but when arriving the publilc baths serviceability temperature, just can open the use of joint door.At this moment the moisture that extra feed tank 12 meetings fall for the heating system supplement consumed automatically, if water inlet A and delivery port F are connected on respectively on the upper and lower conduit road of boiler room, by boiler room water pump forced circulation, whole system just can participate in the building on daytime in winter in the room heating process, reduce the boiler room coal consumption on daytime, but to bleed off the water in the collecting system in case the bursting by freezing pipeline at dusk, preferably water is put in the bucket by a kind of mode, puts back to again in the supply bucket behind second day The sun came up.
Fig. 9 flute profile solar thermal collector heat pipe and attemperater run through connection diagram, because of the heat pipe 2 of flute profile solar thermal collector with have only two mouths of entry and water outlet being connected of attemperater 8, can easily heat pipe directly be passed attemperater 8 by the utmost point, this is just for absorbing heat and independent sealed connection of cooling system providing convenience.As shown in Figure 9, the heat pipe inlet is not communicated with the attemperater wall, but wear bucket and cross and to be connected with the heat pipe other end of collecting system, heat pipe 2 has just become radiating tube through one section in the bucket thus, formed an independent heat radiator circulatory system with collecting system, because only there is the exchange of heat in this system with attemperater, there is not mass exchange, form by thinner pipeline again, volume very little (one 6 meters 4 distributive pipe volumes only are equivalent to the volume of 1 kg of water), so liquid that can freezing point is low injects this system (can big wind or the little extra feed tank of running be installed in bell mouth 14 after filling with), for example alcohol from bell mouth or little water tank 14, vegetable oil, mineral oil, anti-icing fluid etc.As long as the attemperater quality reaches a standard, just can solve the trouble that often discharges water when collecting system uses winter.This cooling system of independently inhaling relatively is fit to be connected with heating system with some small-sized shower systems, particularly the public bathhouse, rural area is not general, friend peasant from by the end of September, at the beginning of 10 months until the coming year 4, May all can not use shower bath, inactive for up to half a year.If adopt this system, as long as being installed, a cover shower bath fills with 1~2 kilogram of liquor or vegetable oil, just can relievedly in the winter time use, bring convenience and material benefit can for surely friend peasant, some units with good conditionsi also can use for reference this design.Need to prove just signal of two radiating tubes shown in Fig. 9, during actual installation, can also can take the measure that increases the radiating tube diameter or use various forms of fin with one or more according to the size of attemperater volume.
When the scheme of installation of draught line was installed reflector on a large scale when Figure 10 assembled on a large scale for the flute profile solar thermal collector on heat pipe 2 frameworks, reflector clocklike can be installed in a row in length and breadth, draught line 18 is connected on respectively in the draught line perforation of reinforcement binding post vertically in a row or connecting plate, the other end is connected with the sunlight follow-up mechanism.Shown in the figure is a hand gear, needs manpower control. draught line shown in the figure has been drawn in the top at reflector, draught line can be connected on the binding post of reflector bottom land reinforcement center in actual mechanical process.Make rotating shaft 16 rotation pulling draught lines 18 regulate all reflector light angles ingeniously by rotating handwheel.If handwheel is linked to each other with motor, rotate the light angle that just can regulate reflector automatically with time relay or light-operated switch control motor.This needs the professional who is proficient in electrician's knowledge expertise and carries out design and installation, perhaps has method more cleverly.
