Detailed description of the invention
The three-dimensional manometer of the present invention is pulsed high-temp solar heat collector (Fig. 1-4) in hot superconduction CPC, this device by thermal cycle nuclear core pipe 1, spiral cold-finger 2, snakelike evaporation tube 3, working medium 4, expansion joint 5, circular black matrix porous metals absorber 6 and, CPC focalizer 7 forms.Wherein thermal cycle nuclear core pipe 1 can be connected (straight tube mouth or external screw thread connection) by the rustless steel of φ 10-50mm, mild steel, aluminium alloy, copper or titanium alloy material through processing expansion joint 5 and termination and form；Condensing tube 2 can be wound around (three-dimensional spiral) in thermal cycle core tube 1 by the bending of φ 1.5-5.0mm rustless steel, aluminium alloy or copper, and by compressing, weld and being formed；Evaporation tube 3 can be connected into, by φ 1.5-5.0mm rustless steel, aluminium alloy or copper product U-tube, swan-neck, the flat serpentine pipe network being interconnected, and circular black matrix porous metals absorber 6 directly foams or is welded on each evaporation tube 3；Working medium 3 adopts ultra-pure water, methanol, ethanol, acetone or R134a material to add gold nano grain, CNT or aluminum nanoparticles and homogeneous suspending agent is formed, and is filled with snakelike evaporation tube 3 pipe network under vacuum conditions.CPC focalizer 7 determines by focusing on multiple according to focusing on multiple design, the spacing of CPC focalizer and height.CPC focalizer 7 directly foams or is welded on the snakelike evaporation tube 3 with circular black matrix porous metals absorber 6, metal foam absorber is circular black matrix porous metals absorber 6, described snakelike evaporation tube 3 centrage overlaps with circular black matrix porous metals absorber 6 centrage, the focal line of CPC focalizer overlaps with circular black matrix porous metals absorber centrage
In the three-dimensional manometer hot superconduction CPC of pulsation, the ultimate principle of high-temp solar heat collector (figure-1 and figure-2) is: under vacuum conditions, nanometer working medium 4 is quantitatively filled with in the snakelike pipe network of three-dimensional planar of said method processing and manufacturing, after sealing, forms three-phase (gas-liquid-solid) coexisting body.Because snake pipe very thin (capillary tube), intraductal working medium 4 can form countless continuous print vent plugs and liquid plug (comprising solid nanoparticles) under capillary effect in pipeline.Solar energy is irradiated reflection and gathers on focal line-circle black matrix porous metals absorber 6 by CPC focalizer 7, the black matrix material of metallic absorber almost 100% absorption solar radiation is also converted to heat energy, black matrix porous metal material has light ray energy absorbability is strong and that thermal resistance is low feature, and heat is uniformly passed to by high thermal conductive metallic skeleton and radiation is delivered on evaporation tube 3 tube wall.When evaporator section metal tube 3 is heated, the working medium being filled with in pipe by thermal evaporation, makes the pressure of evaporator section increase, thus promoting above liquid plug or vent plug to move to spiral condensation segment 2, the liquid plug that closes on also due to the increase of pressure and the transmission of heat and gasify.Thermal cycle nuclear core pipe 1 and spiral cold-finger 2 increase heat transfer area by compressing, weld and attach the modes such as metal film and reduce thermal resistance.When spiral condensation segment 2 successively poured into by vent plug, vent plug is subject to the cooling from thermal cycle nuclear core pipe 1 relatively SAPMAC method fluid, and liquid is formed in condensation, releases heat, is conducted to circulating cooling fluid by tube wall；Condensed fluid forms liquid plug, under the reverse capillary force effect formed, forms pulsation thrust, returns to evaporator section 3, this completes a heat exchange in spiral cooler.So repeatedly, the heat of evaporator section 3, under the panting action that capillary force is formed, has been transmitted to condensation segment 2, carries out the exchange transmission of heat, the operation principle of high-temp solar heat collector in hot superconduction CPC here it is three-dimensional manometer is pulsed.This device utilizes the uniqueness of nanometer pulsating fluid, forms flow-disturbing at tube wall, reduces liquid boundary layer thickness, notable augmentation of heat transfer efficiency.
It is uniformly heated by the solar energy that in the three-dimensional manometer hot superconduction CPC of pulsation, the evaporator section 3 of high-temp solar heat collector is converged by CPC focalizer by black matrix porous material.The heat transfer resistance of this device raises along with the temperature of black matrix porous material and reduces, and when temperature reaches uniform temperature, the reduction trend of thermal resistance diminishes, and continues heating, and thermal resistance increases, and now reaches the heat transport limitation of pulsation Super-conductive conduit.The start-up course of pulsating heat pipe is very complicated, at present the startup of pulsating heat pipe is not had strict definition, it is considered that pulsating heat pipe cooling section and bringing-up section temperature jump are also pulsating heat pipe when forming series of temperature fluctuation and start.
In the three-dimensional manometer hot superconduction CPC of pulsation, before activation, along with heat constantly absorbs, the temperature difference of evaporator section 3 and condensation 2 constantly raises the pulsation Super-conductive conduit of high-temp solar heat collector, is the process of an energy accumulation, and the discontinuous portion of pulsative oscillation is obvious.When instantaneous burst after energy accumulation to certain value, producing quick continuous oscillation, heat quickly transmits at pipeline so that device spiral cold-finger section 2 temperature rises sharply, and evaporator section 3 temperature die-offs, and evaporator section 3 and condensation segment 2 temperature difference diminish.
The Main Function of CPC focalizer 7 is that solar radiant energy improves after several times, being pooled to by the integrated absorption tube of evaporation tube 3 and foam metal black matrix 6, adding the energy density of absorption, thus improve the heat-collecting temperature of solar energy.
