Abstract

The utility model relates to a solar 'condensation fin type heat pipe', which structurally comprises a heat pipe body, condensing fins and a double-sealing cover, wherein a screen-covered imbibition core is inlaid in the heat pipe body. Since a heat collecting section and a condensing section of the heat pipe body are identical in diameter and the screen-covered imbibition core with fine repeatability is arranged in the heat pipe body, heat energy led from the surface of the heat collecting section of the heat pipe body can be transferred by means of working of the heat pipe body, efficiency of the heat pipe body is greatly improved and surface temperature of the heat collecting section of the heat pipe body is reduced. By the aid of the double-sealing cover and the condensing fins, the heat change area between the condensing surface of the heat pipe body and stored water is greatly enlarged, the heat change rate is improved, surface temperature of the condensing section of the heat pipe body is reduced and the length of the condensing section is shortened. Accordingly, 'isothermality effect' of the heat pipe body can be fully developed, temperature of the stored water is basically equal to that of the heat collecting section of the heat pipe body, temperature gradient between the irradiation surface and the stored water is greatly reduced and efficiency is improved. Meanwhile, stored water volume of a header is reduced, energy loss is reduced and the solar 'condensation fin type heat pipe' is reasonable in structural design, simple in technology, low in cost, high in reliability, high in heat transferring rate, fine in cryogenic property in winter, convenient in mounting and using and easy to produce in batch.

Description

Solar energy " condensing fin formula heat pipe "

Technical field

The utility model relates to a kind of solar energy " heat pipe ", particularly a kind of heat exchange area that can increase substantially heat pipe condenser section and thermal-arrest section, exchange rate height, the solar energy " heat pipe " that " repeatability " is good, reliability is high belong to solar energy utilization field.

Background technology

The solar energy of prior art " water copper heat pipe " thermal-collecting tube is actual to be one " the photo-thermal conversion system of heat pipe-type ".Its structure mainly comprises water copper heat pipe, vinyl cover and interlayer scribble bilayer " vacuum glass " thermal-collecting tube of metal heat absorbing coating, described heat pipe constitutes (accompanying drawing 5) by the thermal-arrest section of diameter phi 8～φ 10mm, length 1500～2000mm and the condensation segment of diameter phi 20mm, length 50～100m, described vinyl cover center is provided with the hole that heat pipe can pass, and the thermal-arrest section of described water copper heat pipe is passed the vinyl cover lid and is contained in " vacuum glass " thermal-collecting tube.The condensation segment of described water copper heat pipe inserts in the installing hole of the inner water tank that rubber seal is housed, or in the heating header of central heating system, inserts section and be used for water storage is heated.

The thermal-arrest process of the emittance of the sun in " heat pipe-type photo-thermal conversion system " is: i.e. solar radiation → collection → conduction → exchange → conduction → exchange → water storage is finished water storage heating process in the metal heat absorbing coating collection (irradiation face) of " vacuum glass " thermal-collecting tube, conduction (coated pipe glass bulb), exchange (heat collector tube section surface), conduction (heat-pipe medium), exchange (heat pipe condenser section surface).Under the constant condition of other factors, " transfer rate of solar radiation energy and the collecting efficiency of heat collector; the rising with the illuminated surface temperature of heat collector reduces ", according to heat transfer principle, it is the temperature difference that need there be certain thermograde in heat transmission between two articles, in other condition one regularly, the big more heat transfer rate of this difference is then high more.As establish: the heat exchange and the heat transfer rate of solar radiation energy, water storage temperature and energy are definite value, then from water storage, conduction each time or exchange all will be raised temperature one time, finally cause the thermograde between irradiating surface and water storage to increase considerably, causing the absorption transformation efficiency to solar radiation energy is that the overall thermal efficiency reduces.And the heat pipe effect in solar energy " heat pipe " thermal-collecting tube is to utilize heat pipe " waiting temperature effect ", reduces the thermograde between irradiating surface and water storage, imitates to improve heat.

Because pipeline and the hot water in the header in the central solar heating system can't be discharged use, can not replace out use with cold water, otherwise easily cause the frozen pipe in winter.The energy loss that causes because of the header retention water yield is inevitably, so need reduce the volume of header as far as possible, promptly reduces the sectional dimension of header, and this is restricted the condensation segment length of water copper heat pipe.Though increased heat exchange area with water storage by the diameter that strengthens heat pipe condenser section, had only (0.003～0.006m ²) heat exchange area obviously not enough (as increasing the condensation segment diameter again, then now draw technology can not adopt too greatly because of reducing and the round end processing dimension that contracts, need use that multiple tracks draws high instead, the Sheet Metal Forming Technology of side cut, multiple tracks reducing, the centre also needs repeatedly annealing in process, also need the car limit at last, the end also need add the weldering of punching press copper cap seal, complex process, waster rate height.), the energy in the heat pipe can not in time be spread out of, the thermograde between heat pipe cryosurface and water storage is raised, and the thermal efficiency reduces.Inner vapor temperature when having manufacturer to declare its solar energy water copper heat pipe work reaches 150 ℃, and as publicity point, the deficiency of condensation area has been described also.As calculated: the transfer rate that solar radiation energy is shown up to pair during 150 ℃ of metal heat absorbing coating temperature will reduce by 30%, and the heat radiation divergence loss of the metal heat absorbing coating under the high temperature also will increase greatly.

Because, heat pipe has high heat transfer rate, so can form so-called " waiting temperature effect ", the temperature that is the condensation segment of heat pipe and thermal-arrest section is almost equal, but the deficiency of condensation area causes the characteristic advantage of heat pipe to completely lose, raised the temperature of heat pipe condenser section significantly, the high more then easy more fouling of condensing surface temperature has influenced the reliability of heat pipe.

Because the solar energy water copper heat pipe of employing " gravity operation " mode work, heat transfer medium water are gathered in the liquid pool of heat pipe bottom formation, as pressing standard design, account for 1/3 of heat pipe length overall, still exist winter and freeze quick-fried problem, historical facts or anecdotes border length much smaller (≤30mm).Because the heat transfer rate that heat pipe becomes geometric progression to be higher than copper is vaporization heat absorption and the condensation heat radiation of heat transfer medium under vacuum state that is in the heat pipe, so have only the liquid pool section of heat pipe bottom could realize that " heat pipe working method " conducts heat with efficiently.And the surface area maximum has only 0.0009 (m ²) heat pipe liquid pool section caused its heat exchange area wretched insufficiency (as establishing: this place's temperature difference be k (℃), it is h (W/m that heat is handed over coefficient ². ℃), then heat pipe only has 0.0009 (m with the obtainable energy of liquid pool section of " heat pipe working method " heat transfer ²) k (℃) h (W/m ². ℃)=0.0009kh (W or J/s).), all the other energy that reach the heat collector tube section surface acquisition more than 95% only can conduct heat in the mode that medium steam in managing is heated, and vapor absorption is carried the ability of energy and is only reached about 2J/g. ℃, can't compare with the vaporization heat absorption 2400J/g of water (40 ℃), heat pipe also not exclusively conducts heat with " heat pipe working method ", and the heat transfer rate advantage that heat pipe is had is lost.

The mesh density of the screen type imbibition core of cause in solar energy water copper heat pipe must be not less than 50 orders, and because of the bore of heat collector tube section little (φ 6.5～φ 8.5mm), length big (1500～2000mm), the axial flow resistance of heat transfer medium in the imbibition core that causes heat pipe condenser section to condense is big, easily causes the imbibition core to lose efficacy because of losing liquid; And select for use less than 50 purpose silk screens, then the capillary pumping over pressure of imbibition core is little, and is low from the imbibition ability, will cause the imbibition core to lose efficacy.And common screen type imbibition core is difficult to oneself recovery, promptly so-called heat pipe poor repeatability after losing liquid.

And the water copper heat pipe that installs the imbibition core additional is because of the diameter of condensation segment once big (accompanying drawing 5), cause the silk screen imbibition core in heat collector tube section and the condensation segment well not dock mutually, no matter partial aperture is stopped up or docked to axial mesh dislocation greater than hole for it, all can cause the imbibition core to lose efficacy, and condensation segment multi-layer silk screen liquid sucting core structure is difficult to roll-forming, production is difficult to carry out, so produced the solar energy water copper heat pipe that silk screen imbibition core only is housed in the heat collector tube section, and such heat pipe is when work, moving from imbibition of imbibition core will be hindered mistake fully, can only play the effect of slow medium back flow speed, heat pipe is still with the hybrid mode work with heat medium steam of " the gravity operation " of liquid pool section and remaining set hot arc, and the working method of heat pipe fails effectively to be improved.And water copper heat pipe cost height, and the heat pipe cost that the imbibition core is housed is high more than what do not adorn.

Because the running water water temperature in winter is that be 25 ℃ 7 ℃ of summers, bathing in winter water temperature needs 45 ℃, then be not more than 40 ℃ summer, institute's energy requirement differs more than one times, and differs doubly near between summer in average irradiation energy winter on solar day, causes the too high drawback of solar water heater hot water in winter water temperature in under-supply summer.And the characteristic of " heat pipe " heat transfer medium is near the operating mode the best the medium boiling point, and the operating temperature interval of water is about 77 ℃～227 ℃, and best serviceability temperature is about 152 ℃, so operating mode usefulness inverse ratio in the summer height in winter of water copper heat pipe makes contradiction more outstanding.
