背景技术Background technique
采用重力热管的LED灯具，其大致结构应该为热管下面的热端传热连接若干个LED。热管在这里起的主要作用应该是实现热流密度变换和散热。有关的热流密度变换为大致从约0.5瓦/平方厘米变换为约0.06瓦/平方厘米。The general structure of LED lamps using gravity heat pipes should be that the hot end under the heat pipe is connected to several LEDs for heat transfer. The main role played by the heat pipe here should be to realize heat flux density transformation and heat dissipation. The associated heat flux conversion is approximately from about 0.5 W/cm2 to about 0.06 W/cm2.
考察现有的LED灯具，对于其中的一个长*宽为5*7毫米、总功率0.6瓦、光效21%的LED并且除发光以外的能量全部通过表面传导进入环境、LED全部表面积取1厘米2（0.5*0.7*2+0.1.25*（7+5+7+5）），其散热负荷的热流密度为0.6*（1-0.21）/1=0.474瓦/厘米2。如果不采用散热器，LED的表面温度会超过100℃。Investigate the existing LED lamps. For one of the LEDs with a length*width of 5*7 mm, a total power of 0.6 watts, and a luminous efficiency of 21%, all energy except light emission enters the environment through surface conduction, and the entire surface area of the LED is taken as 1 cm. 2 (0.5*0.7*2+0.1.25*(7+5+7+5)), the heat flux of the heat dissipation load is 0.6*(1-0.21)/1=0.474 W/cm2. If no heat sink is used, the surface temperature of the LED will exceed 100°C.
又，对于一个散热负荷为10瓦的带散热器的LED，以其散热器表面的散热面积200平立方厘米计，则其散热功率密度为0.05瓦/厘米2。作为对照参考：太阳光曝射的峰值强度约为1千瓦/㎡合0.1瓦/厘米2。一个表面积170厘米2的25瓦白炽灯灯泡，由于玻璃泡壳对红外线的阻挡和吸收作用，使得玻璃泡壳表面的温度明显上升。这里，取通过玻璃泡壳的散热功率10瓦，则其通过玻璃泡壳传导的散热功率密度为10/170≈0.0588瓦/厘米2。Also, for an LED with a heat sink with a heat dissipation load of 10 watts, the heat dissipation power density is 0.05 watts/cm2 based on a heat dissipation area of 200 square cubic centimeters on the surface of the heat sink. As a comparative reference: the peak intensity of solar exposure is about 1 kW/m2 or 0.1 W/cm2. A 25-watt incandescent bulb with a surface area of 170 cm 2 , due to the blocking and absorption of infrared rays by the glass bulb, the temperature on the surface of the glass bulb rises significantly. Here, if the heat dissipation power passing through the glass bulb is 10 watts, then the heat dissipation power density conducted through the glass bulb is 10/170≈0.0588 W/cm2.
物体散热功率与散热表面温升的计算公式为：The formula for calculating the heat dissipation power of an object and the temperature rise of the heat dissipation surface is:
Q=K*ΔT*S…………Q=K*ΔT*S…………
式1中Q为散热功率，量纲为瓦；K为从热管冷端表面到空气的传热系数，量纲为瓦/（℃*㎡）；ΔT为空气受热的升温，量纲为K或者℃；S为与空气接触的热管冷端的面积，量纲为平方米。In Formula 1, Q is the heat dissipation power, and the dimension is watts; K is the heat transfer coefficient from the cold end surface of the heat pipe to the air, and the dimension is watts/(°C*㎡); ΔT is the temperature rise of the air, and the dimension is K or ℃; S is the area of the cold end of the heat pipe in contact with the air, and the dimension is square meters.
将Q=10，K=23瓦/（℃*㎡），S=0.02㎡代入；得所述散热模型的温升ΔT≈21.74℃。当S=0.017㎡时得到温升ΔT≈25.58℃。这里所有的散热负荷都以几乎平均的温度通过与空气换热进入环境。实际上，传热系数K的数值还与表面状态包括清洁状态和发射率有关。Substitute Q=10, K=23 watts/(°C*㎡), S=0.02㎡; the temperature rise ΔT≈21.74°C of the heat dissipation model is obtained. When S=0.017㎡, the temperature rise ΔT≈25.58℃ is obtained. Here all cooling loads are exchanged with the air into the environment at almost average temperature. In fact, the value of the heat transfer coefficient K is also related to the surface state, including the clean state and emissivity.
对于LED灯具，其从LED到空气的散热途径远比白炽灯复杂。将LED灯具散热器表面相对环境温度30℃的温升值取21.74℃，并取LED与热管热端之间导热材料的温度降2℃、热管热端管壁的温度降2℃、从热管热端到冷端两相流换热的温度降忽略不计、热管冷端管壁的温度降1℃，则可知所述LED的表面温度将达到30+21.74+1+2+2=56.74℃。鉴于LED的表面温度随环境温度和其本身热流密度变化而变化。当设定环境温度的最高值为30℃、传热系数设定为23以及LED的最高温度为64℃时，每瓦散热功率需要的热管冷端面积至少为15平方厘米；相应的热流密度为0.0667瓦/厘米2。在此工况下，LED10万小时的光衰可望低于20%；而现有少数劣质LED灯具仅仅一个夏季光衰就会达到50%以上。For LED lamps, the heat dissipation path from LED to air is far more complicated than that of incandescent lamps. The temperature rise value of the surface of the radiator of the LED lamp relative to the ambient temperature of 30°C is taken as 21.74°C, and the temperature drop of the heat-conducting material between the LED and the hot end of the heat pipe is taken as 2°C, and the temperature of the wall at the hot end of the heat pipe is dropped by 2°C. The temperature drop of the two-phase flow heat transfer to the cold end is negligible, and the temperature of the wall at the cold end of the heat pipe drops by 1°C, then the surface temperature of the LED will reach 30+21.74+1+2+2=56.74°C. In view of the fact that the surface temperature of the LED changes with the ambient temperature and its own heat flux. When the maximum value of the set ambient temperature is 30°C, the heat transfer coefficient is set to 23, and the maximum temperature of the LED is 64°C, the area of the cold end of the heat pipe required for each watt of heat dissipation power is at least 15 square centimeters; the corresponding heat flux density is 0.0667 W/cm2. Under this working condition, the light decay of LED 100,000 hours is expected to be less than 20%; while the light decay of the existing few low-quality LED lamps can reach more than 50% in just one summer.
中国专利2008200495178公开了一种大功率热管LED照明装置，包括有LED、基座、热管，以及设置有散热装置，基座的一侧设置有一个或者一个以上的LED，热管的一端即热端与所述的基座相连接、另一端即冷端与所述的散热装置相连接。热管与基座之间直接焊接或者填充导热硅脂而不用其他中间传热介质，热阻相对较小，热量传递效率高。具有结构简单，散热效果好，工作可靠的特点。但其采用基座传热连接LED需要设置电气绝缘层实现电气隔离；其在金属热管冷端配置散热翅板作为与空气的换热界面，由于热管冷端与散热翅板之间也有温度降，并且散热翅板的表面温度不均匀，因而增加了散热环节和与空气的换热热阻；散热片产生成本并且不容易清洁；金属热管热端与LED之间需要耐压较高的绝缘层，绝缘层本身存在热阻。LED表面因为热流密度大，同样的热阻，温度降会大许多。由于LED对温度敏感，温度超过65℃LED会较快衰退。因此，削减传热环节和减小传热环节的热阻就具有重要意义。Chinese patent 2008200495178 discloses a high-power heat pipe LED lighting device, including an LED, a base, a heat pipe, and a heat dissipation device. One or more LEDs are arranged on one side of the base. One end of the heat pipe is the hot end and The base is connected, and the other end, namely the cold end, is connected with the heat dissipation device. The heat pipe and the base are directly welded or filled with heat-conducting silicone grease without using other intermediate heat-transfer media, so the heat resistance is relatively small and the heat transfer efficiency is high. It has the characteristics of simple structure, good heat dissipation effect and reliable operation. However, it needs to install an electrical insulating layer to achieve electrical isolation by using base heat transfer to connect the LED; it configures a heat dissipation fin at the cold end of the metal heat pipe as a heat exchange interface with the air, because there is also a temperature drop between the cold end of the heat pipe and the heat dissipation fin, In addition, the surface temperature of the heat dissipation fins is not uniform, thus increasing the heat dissipation link and the heat exchange resistance with the air; the heat sink is costly and not easy to clean; a high-voltage insulating layer is required between the hot end of the metal heat pipe and the LED, The insulating layer itself presents thermal resistance. Due to the high heat flux density on the surface of the LED, the temperature drop will be much larger for the same thermal resistance. Since LEDs are sensitive to temperature, LEDs will decay faster if the temperature exceeds 65°C. Therefore, it is of great significance to reduce the heat transfer link and reduce the thermal resistance of the heat transfer link.

图13中的4个带两个蛇形弯曲段的冷端40的U型变形管状热管1对称布置形成一个筒形体，即每个带两个蛇形弯曲段的冷端40的U型变形管状热管1各占据所述筒形体约四分之一圆周角，这在图14俯视结构示意图中能更直观地看到。Four U-shaped deformed tubular heat pipes 1 with two cold ends 40 of serpentine bends in Fig. 13 are symmetrically arranged to form a cylindrical body, that is, each U-shaped deformed tubular heat pipe with two cold ends 40 of serpentine bends The heat pipes 1 each occupy about a quarter of the circumference of the cylindrical body, which can be seen more intuitively in the schematic top view of FIG. 14 .
同样，还可以令图13和图14实施例中的带两个蛇形弯曲段的冷端40的U型变形管状热管1各占据所述筒形体约二分之一或者三分之一或者五分之一或者六分之一圆周角。Similarly, it is also possible to make the U-shaped deformed tubular heat pipe 1 of the cold end 40 with two serpentine bending sections in the embodiment of Fig. 13 and Fig. 14 each occupy about one-half or one-third or five of the cylindrical body. One-third or one-sixth of the circular angle.
采用蛇形弯曲向上的冷端40的LED灯具其高度可以只有采用拔直向上冷端的30%。The height of the LED lamp with the cold end 40 bent upward in a serpentine shape can only be 30% of that of the cold end that is straight upward.
图13和图14实施例的热管LED灯具也可以只使用单个热管1并将其热端38延长至接近一个圆圈，在热管热端38上布置多个LED2。The heat pipe LED lamps in the embodiment shown in FIG. 13 and FIG. 14 can also only use a single heat pipe 1 and extend its hot end 38 to nearly a circle, and arrange multiple LEDs 2 on the heat pipe hot end 38 .

Each occupies about one-half or one-third or one-fourth or one-fifth of the circumferential angle of the self-cylindrical body.
图13、14和图15、16两实施例的热管LED灯具适合制作LED无影灯。无影灯需要不断变换其空间状态。采用多个U型变形管状热管即使在无影灯光照面作正负29度倾斜时，仍能确保其冷端的工质正常回流。采用弯曲管子制造热管适合大批量生产并且成品率高。部分热管或者LED损坏整机仍能工作。The heat pipe LED lamps of the two embodiments shown in Figs. 13 and 14 and Figs. 15 and 16 are suitable for making LED shadowless lamps. The shadowless lamp needs to constantly change its spatial state. The use of multiple U-shaped deformed tubular heat pipes can still ensure the normal return of the working fluid at the cold end even when the shadowless light illuminates the surface at a tilt of plus or minus 29 degrees.

LED fixtures from 8 to 50 watts. When the heat pipe 1 is provided with a liquid-absorbing core net, it is not sensitive to changes in the inclination angle of the heat pipe, so that the edge of the parabolic rotating body jacket 52 in the light-emitting area can work normally within the horizontal inclination range of plus or minus 10°. Fig. 27 is a schematic structural view of a plate-shaped heat pipe LED lamp.
图27给出本发明第十八个实施例。Fig. 27 shows an eighteenth embodiment of the present invention.
图27中，板状热管LED灯具包括一个板状热管1、LED2和驱动电源42。电气连接界面5采用双线。图27实施例的LED2均布于板状热管1的下面，可以获得平面发光的照明效果。当板状热管1内部布置吸液芯网53时，可以使板状热管1在正负10°或者更大的的水平倾角范围内正常工作。当所述吸液芯网53的吸液能力可以保证将板状热管1的工质通过毛细作用输送到各LED2处供LED2放热蒸发时，甚至可以将均布LED2的发光面朝上并在正负10°或者更大的的水平倾角范围内正常工作。为克服板状热管1管壁两侧的压力差即内部约0.1个大气压和外部1个大气压之差，在板状热管1内部设置支撑件54从里面顶住板状热管1的两内壁。在板状热管1不布置LED2的一面管壁上设置向外凸起的泡状物55可大幅度增加板状热管1的冷端面积。In FIG. 27 , the plate-shaped heat pipe LED lamp includes a plate-shaped heat pipe 1 , LED 2 and a driving power supply 42 . The electrical connection interface 5 adopts two wires. The LEDs 2 of the embodiment in FIG. 27 are evenly distributed under the plate-shaped heat pipe 1 , so that the lighting effect of planar light can be obtained. When the liquid-absorbing core net 53 is arranged inside the plate-shaped heat pipe 1 , the plate-shaped heat pipe 1 can work normally within a range of a horizontal inclination angle of plus or minus 10° or greater. When the liquid-absorbing capacity of the liquid-absorbing core net 53 can ensure that the working fluid of the plate-shaped heat pipe 1 is transported to each LED2 by capillary action for the LED2 to dissipate heat and evaporate, it is even possible to evenly distribute the light-emitting surface of the LED2 upwards and It works normally within the horizontal inclination range of plus or minus 10° or more. In order to overcome the pressure difference on both sides of the plate-shaped heat pipe 1, that is, the difference between the internal pressure of about 0.1 atmosphere and the external pressure of 1 atmosphere, a support member 54 is provided inside the plate-shaped heat pipe 1 to withstand the two inner walls of the plate-shaped heat pipe 1 from the inside. The cold end area of the plate heat pipe 1 can be greatly increased by arranging outwardly protruding bubbles 55 on the tube wall of the plate heat pipe 1 where the LED 2 is not arranged.
带泡状物55的热管壁厚会减小。带泡状物55的热管清洁稍麻烦些。在热管1管壁凃制二氧化钛光触媒涂层，可以利用灯具的光线持续分解与所述二氧化钛涂层接触的有机物污垢，使之成为氮气、二氧化碳和水等简单分子。在热管1管壁凃制二氧化钛光触媒涂层可以参照现有技术实现。The wall thickness of the heat pipe with bubbles 55 will be reduced. The cleaning of the heat pipe with bubble 55 is a little troublesome. Coating the titanium dioxide photocatalyst coating on the tube wall of the heat pipe 1 can utilize the light of the lamp to continuously decompose the organic dirt in contact with the titanium dioxide coating, making it into simple molecules such as nitrogen, carbon dioxide and water. Coating the titanium dioxide photocatalyst coating on the tube wall of the heat pipe 1 can be realized with reference to the prior art.
也可以令图27实施例的热管的正视轮廓为圆角矩形以外的其它形式，譬如图27上方的椭圆形。这样，可以既利用拱形结构良好的抗压性能，又可以使体积小型化和使吸液芯网的毛细作用段不至于过长，略带拱形的发光面照射角优于平面的。It is also possible to make the front profile of the heat pipe in the embodiment of FIG. 27 be in other forms than the rounded rectangle, such as the ellipse at the top of FIG. 27 . In this way, the good compressive performance of the arched structure can be utilized, and the volume can be miniaturized and the capillary action section of the liquid-absorbing core network will not be too long. The slightly arched light-emitting surface has a better irradiation angle than a flat one.
图27实施例的板状热管1的制作可以参照前两个实施例16和17的内容。The manufacture of the plate-shaped heat pipe 1 of the embodiment in FIG. 27 can refer to the content of the first two embodiments 16 and 17.
