Description
Technical field
The present invention relates to cold junction directly to dispel the heat heat pipe LED light fixture.LED is that the English of lasing fluorescence diode is called for short, and can be regarded as the technical term that the art is generally acknowledged.
Background technology
Adopt the LED lamp of gravity assisted heat pipe, its general configuration should be that the hot junction heat transfer below heat pipe connects several LED.The Main Function that heat pipe here rises should be realize heat flow density conversion and heat radiation.Relevant heat flow density is transformed to and is roughly transformed to about 0.06 watt/square centimeter from about 0.5 watt/square centimeter.
Investigate existing LED lamp, for the wide LED for 5*7 millimeter, general power 0.6 watt, light efficiency 21% of one of them long * and energy except luminescence except all by surface conductive entered environment, LED all surfaces is long-pending gets 1 centimetre of 2(0.5*0.7*2+0.1.25*(7+5+7+5)), its heat flow density of dispelling the heat load is 0.6*(1-0.21)/1=0.474 watts/centimetre 2.If do not adopt radiator, the surface temperature of LED can more than 100 DEG C.
Again, be the LED of the band radiator of 10 watts for a heat radiation load, with the flat cubic centimeter of area of dissipation 200 of its spreader surface, then its heat radiation power density is 0.05 watt/centimetre 2.Reference in contrast: the expose to the sun peak strength of penetrating of sunshine is about 1 Qian Wa/㎡ and closes 0.1 watt/centimetre 2.25 watts of incandescent light bulb that surface area is 170 centimetre 2, because glass cell-shell is to ultrared stop and absorption, make the temperature on glass cell-shell surface obviously rise.Here, get the heat radiation power 10 watts by glass cell-shell, then it is 10/170 ≈ 0.0588 watt/centimetre 2 by the heat radiation power density that glass cell-shell conducts.
The computing formula of object heat radiation power and heat-delivery surface temperature rise is:
Q=K*ΔT*S…………
In formula 1, Q is heat radiation power, and dimension is watt; K is the heat transfer coefficient from heat pipe cold end surfaces to air, and dimension is watt/(DEG C * ㎡); Δ T is the intensification of air heats, dimension be K or DEG C; S is the area of the heat pipe cold junction contacted with air, and dimension is square metre.
By Q=10, K=23 watt/(DEG C * ㎡), S=0.02 ㎡ substitutes into; Obtain the temperature rise Δ T ≈ 21.74 DEG C of described heat dissipation model.Temperature rise Δ T ≈ 25.58 DEG C is obtained as S=0.017 ㎡.Here all heat radiation loads all with almost average temperature by with air heat-exchange entered environment.In fact, the numerical value of Coefficient K also comprises clean conditions with surface state and emissivity is relevant.
For LED lamp, its sinking path from LED to air is complicated more than incandescent lamp.The temperature rise value of LED lamp radiator surface relative ambient temperature 30 DEG C is got 21.74 DEG C, and the temperature of getting Heat Conduction Material between LED and heat pipe hot junction falls 2 DEG C, the temperature of heat pipe hot junction tube wall falls 2 DEG C, fall from heat pipe hot junction to the temperature of cold junction two phase flow heat transfer ignore, the temperature of heat pipe cold junction tube wall falls 1 DEG C, then the surface temperature of known described LED will reach 30+21.74+1+2+2=56.74 DEG C.In view of the surface temperature of LED changes with environment temperature and the change of itself heat flow density.When the peak of set environment temperature be 30 DEG C, heat transfer coefficient be set as 23 and the maximum temperature of LED be 64 DEG C time, the heat pipe cold end area that every watt of heat radiation power needs is at least 15 square centimeters; Corresponding heat flow density is 0.0667 watt/centimetre 2.Under this operating mode, the LED10 light decay of ten thousand hours is expected lower than 20%; And existing minority LED lamp inferior only one summer light decay will reach more than 50%.
Chinese patent 2008200495178 discloses a kind of high power hot pipe LED illuminating apparatus, include LED, pedestal, heat pipe, and be provided with heat abstractor, the side of pedestal is provided with one or more than one LED, and one end of heat pipe and hot junction are connected with described pedestal, the other end and cold junction are connected with described heat abstractor.Directly weld between heat pipe with pedestal or fill heat-conducting silicone grease and without other intermediate heat media, thermal resistance is relatively little, heat transfer efficiency is high.There is structure simple, good heat dissipation effect, the feature of reliable operation.But it adopts pedestal heat transfer connection LED to need to arrange electric insulation layer and realizes electrical isolation; It is at metal heat pipe cold junction configuration radiating fin plate as the heat exchange interface with air, and owing to also there being temperature to fall between heat pipe cold junction and radiating fin plate, and the surface temperature of radiating fin plate is uneven, thus adds heat radiation link and the heat exchange thermal resistance with air; Fin produces cost and is not easy to clean; Needing withstand voltage higher insulating barrier between metal heat pipe hot junction and LED, itself there is thermal resistance in insulating barrier.LED surface is because heat flow density is large, and same thermal resistance, temperature is fallen can be many greatly.Because LED is to responsive to temperature, temperature can very fast decline more than 65 DEG C of LED.Therefore, the thermal resistance of cutting down heat transfer link and reduction heat transfer link is just significant.
