1, solves the technical scheme of heat collector fragmentation: with the organic light transmissive material that contains UV resistant technology, one-shot forming sawtooth light-passing board, substitute glass tube with vacuum, constitute in light weight, chip-proof vacuum sawtooth automatic track solar heat collector.
2, solve the technical scheme that season and time difference produce the light reflection: use heat collector to automatically track sunlight, compensation is because the solar angle deviation that season, difference produced.Automatically tracks sunlight mainly is made up of solar angle sensor, micro machine, suspension holdfast and several elevation angle displacement drive, universal circulator, it include make the heat collector day side the plane perpendicular to a certain arc track, one end of this arc track is perpendicular to the wall facade, and heat collector repeats to come and go the mechanism of displacement automatically along this arc track.Automatically tracks sunlight need solve following four problems:
1. solve soft, hard water-supply-pipe and can't follow the technical scheme of heat collector displacement: convert the displacement of the lines of waterline to angular displacement with universal circulator.Universal circulator be by, the water pipe of two butt joints, thin conduit are inserted in the thick water pipe, are provided with the pipe joint that can make up, decompose near an end of wall eye, said joint includes the connection and the leakage preventing mechanism of opposite spin relatively.
Because security needs, install and maintenance work must be in the at arm's length scope in window place.So all waterlines can not be away from window.If along serving as the axle rotation, hardwired water-supply-pipe can't be followed the heat collector displacement to heat collector with the base.If, though adopt the spring hose to follow,, the life-span is very short, bears the hydraulic pressure ability, and hose loses flexibility after applying insulation material, also can't follow the heat collector displacement.Have only, heat collector is the axle rotation with the upper edge, is equipped with universal circulator, is only feasible.
2. solve the technical scheme of solar angle sensor: the solar angle sensor is mounted on the heat collector, and said sensor is to be installed on the shade plate by several light-sensitive elements, is vertically mounted on the sunshading board institute five equilibrium on the shade plate.If the solar angle sensor is installed on windowsill or the wall, detection be absolute incidence angle, control complicated cost height.The solar angle sensor is installed on the heat collector, detection be the incidence angle deviation, it is low to control simple cost, reliable.
3. the axis that solves universal circulator and hang folding is point-blank technical scheme not: if not point-blank, just can't convert displacement of the lines to angular displacement.The way that solves is, the water-supply-pipe exit in the heat collector both sides, and each increases a Z type pipe joint.
4. solve heat collector repeats to come and go displacement automatically along arc track technical scheme: elevation angle displacement drive is by several fixing on several fixing on heat collector high strength foldings and suspension holdfast high strength foldings, make an edge of heat collector, straight line back and forth movement on threaded screw rod, spacing group of magnets is contained in the top of threaded screw rod.
Adopt two cover elevation angle displacement drive, the heat collector stability is good, and wind loading rating is strong.Because speed reducing ratio is very big, when driven wheel stops operating on threaded screw rod, need not locking mechanism, heat collector can not move with the wind yet.
3, solve organic material and constitute light-passing board, the technical scheme that undercapacity is difficult to vacuumize: the support usefulness of vacuum plate heat collection device is glass bar at present, and the material of fixing glass bar has blocked a certain amount of light.Support when too much, can occur the different cold and hot exchange phenomenon of degree between heat dump and the atmosphere.The quality that vacuum supports is the key point of heat collector.Below solve from two aspects:
1. strengthen the whole plate intensity of light-passing board self: be used to exempt from the sawtooth of the sawtooth light-passing board that the gradient installs, possessed the best three-legged structure of stability in the mechanics.Behind the organic light-passing board one-shot forming in the plane sawtooth light-passing board, whole plate intensity has improved hundred times.Also the vacuum for the some contact supports the condition of having created.
2. adopt high adiabatic, the low vacuum that is in the light to support: it is to be become with heat insulation grid groups of holders by the printing opacity net grid support that vacuum supports, wherein, said printing opacity net grid support is to constitute net grid support with organic light transmissive material, the side that this support contacts with heat dump, assembled the bar that heat-insulating material is made, wherein, said heat insulation net grid support is to make net grid support with heat-insulating material, and the support contact-making surface of said printing opacity net grid support and heat insulation net grid support all is the circular-arc of blade-like or projection.
Adopt net grid support, be because, can be processed into blade-like with supporting contact-making surface, and glass do less than.That the unit grids area of net grid support can be done is very little, and glass do less than.The coefficient of heat conduction of organic light transmissive material is little more a lot of than glass, and cold and hot exchange is also just little a lot of naturally.Heat insulating strip is very thin, and is close to the heat dump side, so it is atomic to shut out the light.It is in order to improve the hear resistance of organic light transmissive material that the printing opacity net grid support is equipped with heat insulating strip.Adopting the mode of inserting volume to make net grid support is that cost is low because technology is simple.Support contact-making surface and adopt the Points And lines way of contact, thermal insulation is better.Net grid support does not rupture under the external force effect, and glass bar supports easy fracture.With the polyurethane foam between alternative heat dump of adiabatic net grid support and the vacuum shell, be in order to improve thermal insulation.
4, solve the technical scheme that material leaks slowly: the material aspect can't solve slowly and leak, but can solve the side.In the time of can not dispatching from the factory because of bicycle, can't accomplish that tire leaks gas never, and be rejected use.Vacuum ftercompction mouth is set on heat collector, it is a kind of for a vacuum ftercompction mouth, can make up some roads sealing mechanism of decomposition at any time repeatedly, said some roads sealing is vertically to compress seal washer with the leakproof cover along the stud track, with elastic rubber tube unidirectional blocking aspirating hole.Reach and replenish vacuum pressure simply, conveniently, rapidly.
5, solve heat collector vacuum and descend after, the user is difficult for the technical scheme in time found: the vacuum sensor simple, reliable, that the life-span is long is set on heat collector, converts pressure to the signal of telecommunication, offer electronic acoustooptic and report to the police.Make the user find in time whether vacuum descends.Vacuum sensor it include electronic switch, the housing of the sealing of the pressure change that can follow vacuum room and deformation, said housing is to make with bellows or bending metals pipe.Said electronic switch is to constitute with magnet and Hall element.
6, solve heat collector and freeze stifled technical scheme: solving to freeze to block up has three kinds of approach: 1. improve frost resistance, promptly heat collector freezes in the stifled process repeatedly, and heat collector can be by bursting by freezing.2. improve freeze-proof,, prevent that the water temperature of heat collector is down to zero following promptly with ways such as electrical heating.3. improve freexing tolerance, promptly improve the heat insulating ability of heat collector or the pondage of increasing heat collector, it is stifled that heat collector is not frozen within a certain period of time.
Analyze frost resistance: the order that freezes of control heat collector internal water, still in heat collector, establish freezing expansion absorption device, what be to use also that the material with retractility makes heat collector easily freezes the position.This approach exists, complex process, high easy the wearing out of elastomeric material cost.Even if frost resistance reaches a standard, heat collector can be by bursting by freezing.The water of emptying has not increased the quality of energy storage.The cryogenic energy that store night will be offset effective heat energy of equivalent on daytime.
Analyze heat insulating ability: improve the heat insulating ability of heat collector or strengthen the pondage of heat collector, be have circumscribed.Can't resist contingency, can't know promptly how many minimum temperatures of each cold current is, can't know the bottom line that to break through heat insulating ability.Reasons such as current material kind and price are restricted the raising heat insulating ability.
As can be seen, improve freeze-proof after comprehensive the comparison, economical and practical, simple and reliable.According to different regions, choose concrete scheme, 1. the mode with the automatic local heating of tubing pump prevents the accidental cold current bursting by freezing heat collector that arrives.2. with the automatic emptying mode of heat collector, the assurance long-term work is not frozen stifled phenomenon at the heat collector that freezes under the stifled temperature.The automatic emptying of heat collector is by water pump during with the whole suction water storage tank of the water in the heat collector, the closed electromagnetic valve at high water level place, and air enters heat collector from the inlet duct on the aqueduct.
Dual mode all has manual emptying.Manually emptying is used for power failure, water pump fault, maintenance.Be with power saving, safety with upper type than ribbon heater, electricity companion.There are not the power failure mistaken ideas.
The reliability of the antifreeze sensor of sharing is the mode that contacts with measured medium.Antifreeze sensor is to be connected on the circulating water pipe with hollow bolt or hollow nut, and temperature sensor repeatably is placed in the water of circulating water pipe.
7, solve the present not good enough technical scheme of vacuum plate heat collection device heat insulating ability: around the opening of vacuum shell, be provided with the exumbrella edge of certain width, said vacuum shell, the inboard is equipped with the heat radiation barrier film, and the outside is equipped with heat-insulation layer.Block the heat radiation of heat dump with the heat radiation barrier film, though simple, effective.With the polyurethane foam of the alternative vacuum support of heat insulation net grid support cheaply, purpose is that the raising thermal insulation reduces cost.Polyurethane foam moves on to the vacuum shell outside, and its supporting role reverts to insulation effect, and its heat insulating ability is not fully exerted.The heat collector heat insulating ability and the ratio of performance to price have been improved.
At present, the vacuum plate heat collection device is at the heat dump shady face, supports as vacuum with polyurethane foam.Polyurethane foam is in vacuum layer, and heat insulating ability does not obtain performance.Under the situation of large tracts of land Long contact time, heat conductivity is that significantly the temperature difference is big more obvious more.
Influence another reason of heat insulating ability, heat dump is unsettled in vacuum shell, have certain fixingly and is connected, produces hard connection when two circulating water pipes of heat dump are drawn in vacuum shell.When especially welding, its cold and hot conduction is tangible.
8, solve light-passing board and expand with heat and contract with cold, the technical scheme of the bad heat collector that expands: the coefficient of expansion of organic light transmissive material is big more a lot of than metal, generally speaking, must reserve the expansion space all around.Reserve the expansion space and make structure and process complications.The size that expands is very easily destroyed vacuum seal.The way that solves is to absorb the change in size of vertical direction with the sawtooth of sawtooth light-passing board.Absorb the change in size of horizontal direction with the semicircle bending of sawtooth light-passing board both sides projection.
9, solve the sawtooth light-passing board technical scheme of sealing reliability all around:
Structural relation all around is to vacuum-packed reliability.Make the exumbrella edge that forms a certain width all around of vacuum shell opening.Fluid sealant acts on exumbrella along on this big plane, because contact area is big, has improved adhesive force, distortion power, the shearing force of glue relatively.
10, solve the technical scheme of heat collector wind loading rating: the sheet material of vacuum shell can not very thick situation under, reasonable structure is extremely important.Be related to safe coefficient, wind loading rating, service life.Be used for the axle and the axle sleeve of automatic tracks sunlight, if decompose on the side and suspension holdfast of heat collector, because application point is concentrated, the action direction of power is bad, can make vacuum shell deformation.It is complicated that heat collector is installed, inconvenient maintenance.
The mode that adopts axle and axle sleeve to concentrate, promptly adopting axle and axle sleeve is the high strength folding of one, and it is separately fixed on four angles on exumbrella edge, fixes with the porous of high strength folding, disperses the pulling force to vacuum shell exumbrella edge, is simple and effective way.
11, solve the dynamic junction of universal circulator, dynamically the technical scheme of insulation:
With insulation material universal circulator is wrapped up, the insulation material laterally disconnects at the seam crossing that dynamically connects of universal circulator, at its gap wear-resisting, sealing mechanism is set.
12, solve the bound temperature control mode and be not suitable for heat collector coolant controlled technical scheme:, substitute the control of bound temperature with the control of the self-adapting type temperature difference.The control of the self-adapting type temperature difference, the temperature of the similar control water that when the river rises the boat goes up.It is bad can not sunlight to occur, and water temperature does not reach the higher limit of setting, and tubing pump does not change.Water temperature can not occur and surpass the higher limit of setting, tubing pump changes a phenomenon of not stopping.
13, the cold water pipe that solves the heat collector below is away from window, and pipeline intensity is bad and can't apply the technical scheme of heat-insulation layer: heat dump is the temperature difference of utilizing water, and heat is collected in self-loopa.So the heat dump circulating water pipe must be hot-water line last, cold water pipe is down, water temperature could circulate.Installment work must be to stand in the at arm's length scope of window.Constraints has determined that the cold water pipe of the flat plate collector that only changes all is the convention of drawing from the below, and two water pipes are drawn from the top of heat collector both sides respectively.
14, solve the technical scheme that install in the heat collector high-altitude and maintenance is inconvenient: will hang fixed mechanism and separate with heat collector.Two circulating water pipes place of registering one's residence adopts pipe joint to connect.Accomplish to install simple.
Maintenance is adopted and not to be dismantled suspension holdfast, simply with heat collector with after suspension holdfast separates, just can be with heat collector by the way of entering house.
