1. propose a kind of fuzzy heat transfer system Thermal design of practicality:

From Pyrology, although there is the comparatively complicated thermaltransmission mode of heat conduction, convection current, radiation three kinds in any heat transfer system, when actual heat exchange all simultaneously, various heat transfer link, electrically, mechanical, structure, the factors such as environmental condition are different, and active basic mode is also different; Therefore requiring that the heat transfer model that there is no need in not bery strict practical application by complexity carries out high-precision calculating, the main mode solving various heat transfer link should be caught to ignore the interference of other secondary modes fuzzy; As the LEDbulb lamp heat transfer system in LED illumination light source, LED chip is thermal source, and in the structure that the confined space is little, no matter the heat that LEDbulb lamp thermal source produces, adopt how finally still will carry out heat with air hands over Change, heat is dispersed in air.Therefore key first transmits out rapidly from thermal source chip by heat, is then only and heat is fallen apart in air; Heat transmits out from thermal source chip and is mainly determined by heat conductivility; And carry out heat with air and hand over Change mainly to be determined by convection current and thermal-radiating ability, material conducts heat performance almost can be ignored under certain condition.

Ordering-the invention in LED illumination light source heat transfer system construction design method be: first to heat conduction, convection current, the LED heat transfer system of radiation fuzzy set, set up heat-transfer device fuzzy heat conduction framework and the fuzzy heat radiation Computational frame of radiating element respectively, the heat conduction main mode solving heat-transfer device heat transfer link is caught to ignore fuzzy convection current, the interference of radiation mode, solution radiating element heat transfer link convection current or radiation main mode is caught to ignore the interference of heat conduction, use Semiconductor Physics, the basic theoretical knowledge of heat transfer theory, experimental data, inaccuracy is carried out with quantitative test data, uncertain heat calculates, the start-up temperature of thermal design heat-transfer device, samming temperature, samming body maximum heat capacity, estimate the safe heat transfer amount of heat-transfer device, carry out inaccuracy, uncertain heat calculate, the insulating radiation outer jacket surface of thermal design radiating element is long-pending, convection transfer rate or heat radiation yarn number, the thermal parameters such as estimation radiating element true heat gain value, then the technology knowledge and experience data that comprehensive correlative technology field accumulates complete the whole hot computational process of heat transfer system and are optimized coupling, assemble the heat-transferring assembly of low design cost, carry out emulation experiment, detection, be finally made into high performance-price ratio LED illumination light source.

Ordering-the invention, by the Fuzzy Calculation framework of this kind of heat conduction be based upon on Semiconductor Physics, heat transfer theory basis, convection current, radiation fuzzy set, has obvious antijamming capability to input information; Effectively can utilize inaccuracy, uncertain and incomplete information carry out heat calculate and decision-making; Integrated use Qualitative Knowledge (comprising Heuristics) and Quantitative Knowledge can complete hot computational process, there is the heat transfer system method for designing of lower design cost, be defined as fuzzy heat transfer system Thermal design; The heat transfer system structure made by this method for designing is defined as fuzzy heat transfer system structure;

Heat management design is a high-precision subject, but in actual applications, particularly in civilian or general field, also needs the cost performance considering commodity; Cost performance is the performance number of commodity and price value ratio, and be the metering method of a kind of quantification of the bought degree of reflection article, whether under just cost performance should formerly meet the prerequisite of performance requirement, then it is suitable to weigh price; Performance requirement as general illumination or civilian room lighting and special lighting is different, people regard the important indicator of shopping goods as the cost performance of indoor LED illumination light source product, people are reluctant to buy deficient heat conduction, owe the product of inferior quality of heat radiation, also be reluctant to buy heat radiation, cross the low cost performance product of heat conduction, it is desirable that the high performance-price ratio LED illumination light source product of safety, convenience, reliable, the suitable material benefit of price; And with fuzzy heat transfer system structure fabrication LED illumination light source product, can by the Optimized Matching of the heat-transfer device of various standard and radiating element, the different heat-transferring assembly required of combination easily, makes the LED illumination light source product of high performance-price ratio.

Fuzzy heat transfer system Thermal design is the high performance-price ratio heat transfer system method for designing of a kind of practicality, simple novel concept, not only be applicable to the heat transfer system in LED illumination light source, and be applicable to the heat transfer system of other applications, it is the one innovation in the practical application of heat transfer system method for designing, break through

2. disclose a kind of radial phase transformation samming body heat-transfer device of innovation;

The heat transfer property of phase-change devices is that any metal material is incomparable, the radial phase transformation samming body of Ordering-the disclosure of the invention is again current state-of-the-art phase-change devices, from broadly saying that it is the quick samming being reached face, body, multidimensional by radial phase transformation quick conductive, it not the axial thermal conductivity of general phase transformation heat pipe, neither phase transformation temperature-uniforming plate (soaking plate) heat sink, only heat-conduction even temperature on plate face, radial phase transformation more quick conductive can reach face, body, the quick samming of multidimensional, radial phase transformation samming physical efficiency heat conduction thus eliminate LED chip high temperature accumulation point faster, pass through and a large amount of experiments such as the preliminary startability of the radial samming device of LED and operating temperature characteristic are confirmed: in startup temperature-rise period, LED radial phase transformation samming body has more excellent quick conductive performance, uniform heating property, the radial heat transfer of the structures shape of radial heat transfer under similarity condition transmits more heat than axial heat conduction, larger heat power, and have larger thermal capacity, the a large amount of heat assembled in LED die can be sent to the heat-transfer area of phase transformation samming device with the speed of>=340m/s, high temperature accumulation point in rapid elimination LED die, heat flow density>=220W/cm simultaneously ², heat conduction power>=220W/cm ²performance, can by great power LED heat sink structure, expand to can control phase transformation start-up temperature, heat transfer rate, thermal capacity size heat-transfer device, make LED die can be more stable and work efficiently, solve general heat sink structure heat-transfer rate slow, thermal capacity is little causes high temperature in LED die to assemble the infringement caused,

Because the radial heat transfer of structures shape of radial phase-change heat transfer is than other phase-change devices more outstanding, therefore radial phase transformation samming device heat transfer rate is faster applied, higher heat flow density, the feature that heat conduction is more powerful, by the volume to LED radial phase transformation samming body device, vacuum, the boiling point of heat-transfer working medium and filling amount, the structure of capillary wick heat-conducting system and the heat transfer property of phase-change devices, start-up temperature, the correlation of heat transfer rate, can require to optimize phase transformation cavity according to the cost performance of fuzzy heat transfer system structure, optimize heat transfer rate, optimize heat-transfer working medium, adjust radial phase transformation samming body manufacture craft, control start-up temperature, samming temperature is not more than LED chip operating temperature, reduce the cost of manufacture of phase-change devices, in thermal design, the maximum permission junction temperature value of LED chip can be calculated easily according to the Fuzzy Calculation framework of fuzzy set to light emission rate and the requirement in life-span according to different product, design corresponding samming temperature, configure corresponding heat protective device simultaneously, control LED junction temperature is no more than the maximum permission junction temperature value of LED chip, the internal stress brought of avoiding heating up fast and lower the temperature interferes with each other problem, extend the service life of all parts, improve the cost performance of LED illumination light source product,

Due to the structural change structure of current capillary wick heat-conducting system of radial phase-change heat transfer, the defect during practical application of gravity phase-change devices can be solved, the radial phase transformation samming body heat-transfer device of this innovation, not only be applicable to the heat transfer system in LED illumination light source, and the heat transfer system of applicable other field, be another revolution of current phase change technique in the practical application of heat transfer system structure.Be the one innovation of great power LED heat sink structure, break through.

3. disclose a kind of fuzzy heat transfer system heat structure of LED illumination light source of practicality:

Known by fuzzy heat transfer system construction design method, though heat management design is a high-precision subject, there is the comparatively complicated thermaltransmission mode of heat conduction, convection current, radiation three kinds in each diabatic process simultaneously, but there is no need in actual applications to carry out accurate Calculation Te Do in the structure that the confined space is little by the heat transfer model of complexity, in hot biography process, the impact of many parameters, boundary condition almost can be ignored and fuzzyly to disregard;

The heat transfer path of current LED illumination light source heat transfer system (as LEDbulb lamp lead integrated heat dissipation metal structure) is: LED chip-metal substrate one is with the metal heat sink-air of radiating fin, heat transfer system is active is the heat conductivility of metal material, when dispelling the heat, contribution margin is too little, if design improper probably making to become the low cost performance product of initial failure:

The thermal design heat transfer path of the present invention's fuzzy heat transfer system heat structure is: LED chip-radial phase transformation samming body (heat-transfer device)-shaft insulation is to heat radiation overcoat (radiating element)-air; As steeped in the little structure of this confined space in LED ball, no matter adopt how finally still will carry out heat with air hands over Change, heat is dispersed in air, and it is crucial for therefore heat being transmitted out from thermal source chip rapidly, is then only and heat is fallen apart in air; Heat transmits out from thermal source chip and is mainly determined by radial phase transformation samming body heat-transfer device heat conductivility: and carry out heat with air and hand over Change mainly to be determined by the convection current of the overcoat that axially dispels the heat and thermal-radiating performance;

The heat transfer system of special small confined space, as in the LEDbulb lamp confined space, according to fuzzy heat transfer system Thermal design, using heat-transfer device as thermal source, when the temperature difference of heat-conduction even temperature body and the sleeve surface that axially dispels the heat is less, distance is less, and thermal conductivity factor is more inessential; The test data of relation according to disclosed thermal conductivity factor and conductive-convective heat radiation is known, if distance is less than 5mm, as long as so thermal conductivity factor is greater than 5, its heat-sinking capability is just complete to be determined by convection current, radiation, the impact of the heat conductivility of fuzzy heat radiation lagging material can be ignored, can easily according to actual application environment, the heat radiation overcoat device that Optimized Matching is different, be combined into the fuzzy heat transfer system heat structure heat-transferring assembly of a kind of low cost, practicality, standard

Because LED electrical light source is a kind of semiconductor devices being different from other electric light source principle of luminosity, know according to Semiconductive Theory rudimentary knowledge and quantitative semiconductor junction temperature data qualitatively: as long as to be less than maximum permission junction temperature temperature (being generally 125 DEG C) just passable for general power device junction temperature, but in great power LED cooling design, because LED junction temperature has considerable influence to the light emission rate of LED and life-span, the higher meeting of junction temperature makes the light emission rate of LED lower, life-span is shorter, according to the Heuristics of reality, the junction temperature of white light LEDs and the relation data of relative light emission rate: when junction temperature 25 DEG C, relative light emission rate is 1, during junction temperature 70 DEG C, relative light emission rate reduces to 0.9, when junction temperature 50 DEG C, the life-span is 90000 hours, during junction temperature 80 DEG C, the life-span drops to 34000 hours.Therefore to require to press the actual application environment of product more much lower than 125 DEG C for LED junction temperature, and in actual fabrication, how control LED junction temperature is the key of LED illumination light source product;

The present invention is according to the feature of LED electrical light source semiconductor chip, with the lighting source that this fuzzy heat transfer system heat structure is made into, the environment for use cost of semiconductor devices can be reduced, both the reliability requirement of product had been met, substantially increase again the cost performance of product, not only be applicable to the heat transfer system in LED illumination light source, and the heat transfer system of applicable other field, be an innovation in current practical application heat transfer system structure, break through.
