-4After the negative pressure of Pa, vacuumize interface by superconductive medium vacuum cavity injected an amount of nano-fluid superconductive medium, make be full of the nano-fluid superconductive medium in the close teeth groove of imbibition core of cavity inner surface after, superconductive medium is vacuumized interface is sealed.During nano-fluid work, fluid is in the gas-liquid two-phase state, and the boiling point of nano-fluid under vacuum condition is lower than the operating temperature of LED, and radiator just might operate as normal.
Operation principle of the present utility model: because vacuum environment in the vacuum cavity, the boiling point of the nano-fluid superconductive medium in the vacuum cavity can be than much lower under the normal pressure, and is more volatile.Led light source with the heat transferred vacuum cavity after, temperature rising nano-fluid superconductive medium is heated, vaporized expanding absorbs heat, stores potential.Nano-fluid expansion back forms pressure differential, and the nano-fluid superconductive medium flows to the cavity top under action of pressure, and the nano-fluid superconductive medium is met cold at the cavity top, liquefaction, and the while liberated heat discharges potential.The vacuum cavity upper end absorbs nano-fluid superconductive medium liberated heat, and cavity top heat rises, and heat is delivered in the air with convection current, conduction pattern by cavity outside radiating fin, realizes reducing fast the purpose of LED temperature.The vacuum cavity inner surface adopts close teeth groove structure, and liquid forms backflow by the conduit of close teeth groove.The nano-fluid superconductive medium of liquefaction is back to cavity bottom along groove under the effect of gravity.
Increase external aluminium fin number, size, increase area of dissipation, improve rated power.
The particle of Nano grade is compared with neat liquid, and the random motion in fluid of the nano particle in the nano-fluid makes the fluidized bed laminar sublayer be damaged, and flow turbulence intensity also strengthens thereupon, thereby has reduced heat transfer resistance, has strengthened heat transfer.In liquid, add nano particle, on the one hand be since the thermal conductivity factor of solid greater than the thermal conductivity factor of liquid; Be because under identical particle volume content situation on the other hand, interfacial area between nano particle and the liquid is much larger than the interfacial area of millimeter or micro-size particles, two aspects all make the thermal conductivity factor of fluid increase, thereby strengthened heat transfer, the heat transmission occurs in particle surface, particle and particle, particle and liquid, interaction between particle and wall and collision, also increase flow disturbance intensity, strengthened the energy transfer process of nano-fluid inside, made heat-transfer capability be promoted, the overall temperature difference of radiator can be littler, and thermal conductivity factor can be higher.Because nano particle is very thin, and very big surface area is arranged, thereby be more suitable for conducting heat.The specific area of the particle of diameter 10nm is 1000 times of surface area of diameter 10 μ m particles.The specificity of nano-fluid is the small-size effect of nano particle, makes its behavior more close to fluid molecule, and the strong Brownian movement of nano particle is conducive to the stability that nano-fluid suspends.
Nano-fluid is not simple liquid, solid mixture, in the suspension of nano particle, because the activity of particle surface makes them be easy to reunite together, formation have some weak linkage interfaces than macro aggregate, the aggregation extent of nano particle is more big, and the particle cluster mean radius is also more big, and thermal conductivity factor is just more little, excessive aggregate easily causes deposition, will lose the increase heat-conducting effect.3 kinds of methods are arranged with the suspension stability problem that solves nano-fluid: the one, change the pH value of suspension; The 2nd, use surfactant and dispersant; Three are to use ultrasonic vibration.The purpose of all these methods is to suppress the generation of particle aggregation, to obtain suspending stabilized nano-fluid by changing the surface-active of particle.
Radiator casing will have compatibility with working medium, if it is incompatible, working medium and pipe wall material react, produce incoagulable gas, when radiator work, this gas was blown to dash by vapor stream and coagulates the formation vent plug that section gathers together, thereby effective condensation area is reduced, thermal resistance increases, and heat transfer property worsens, and heat-transfer capability reduces even lost efficacy.The LED temperature need be controlled in 60 ℃ simultaneously, and therefore, the boiling point of nano-fluid under vacuum condition is lower than the operating temperature of LED, and radiator just might operate as normal.Need nano-fluid operating temperature boiling point under vacuum environment to be lower than 30 ℃.For maximum improves radiator performance, radiator selects for use copper to do shell, and copper thermal conductivity factor height and LED thermal contact resistance are little; Do working medium with the water that specific heat capacity is very big, water and copper have compatibility simultaneously.Nano-fluid improves 15-25% than pure single distilled water working medium thermal conductivity factor.
Technique effect of the present utility model and superiority: the heat conduction of traditional heat-dissipating device is the motion that relies on the metal inside free electron, is the sensible heat exchange that does not have metamorphosis; The heat conduction of nano-fluid superconducting radiator is the liquefaction that utilizes the nano-fluid medium, the latent heat exchange of vaporization phase transformation.Same material, same quality raises 1 ℃ equally, and the latent heat exchange is 500 times of sensible heat exchanges.The nano-fluid medium can store the latent heat of vaporization in the vaporescence, and the latent heat of vaporization and pressure are inversely proportional to, and pressure is more little, and the medium vapourizing temperature is more low, and the latent heat of vaporization that stores during vaporization is more many.Under vacuum environment, the directed transmission of nano-fluid medium heat speed is also very fast, surpasses the heat conduction of traditional heat-dissipating device.Numerically, the thermal conductivity factor of nano-fluid superconducting radiator is at 20000-25000w/mk, and common aluminum alloy radiator thermal conductivity factor is 200w/mk approximately, and the nano-fluid steam of cavity is to be in saturation state, and the pressure of saturated vapor is decided by saturation temperature.Therefore under the vacuum condition, the nano-fluid superconducting radiator has good isothermal, and the temperature difference of radiator top and bottom is in 3 ℃.When integrated (COB) LED power during at 50W, environment temperature is at 30 ℃.The chip temperature of the LED of employing conventional aluminium fin structure is at 75 ℃, and aluminium fin temperature is at 60 ℃; At 50 ℃, nano-fluid superconducting radiator temperature is at 43 ℃ with the led chip temperature of volume nano-fluid superconducting radiator in employing.The chip temperature of led chip has reduced by 25 ℃, guarantees that the LED temperature is below 65 ℃.
The thermal conductivity factor of nano-fluid superconducting radiator and nano-fluid, fluid content, close slot sizes etc. have substantial connection.
The utility model utilizes nano-fluid composite phase-change Rapid Thermal conduction technique, accelerates heat conduction; Utilize the aluminium material heat radiation, break through LED heat conduction, heat dissipation problem, reduce the LED temperature.
