一．热管散热技术原理
典型的热管由管壳、吸液芯和端盖组成，将管内抽成一定的负压后充以适量的工作液体，使紧贴管内壁的吸液芯毛细多孔材料中充满液体后加以密封。
管的一端为蒸发段（加热段)，另一端为冷凝段（冷却段），当热管的一端受热时吸液芯中的液体蒸发汽化，蒸汽在微小的压差下流向另一端放出热量凝结成液体，液体再沿多孔材料靠毛细力的作用流回蒸发段。
如此循环不己，热量由热管的一端传至另—端。
Typical heat pipe is composed of shell, suck liquid core and end cover, after pulling the tube into a negative pressure filling with just the right amount of working fluid, make the pipe close to the wall of capillary suction liquid core to be sealed after filled with liquid in porous materials.
One end of the tube for evaporation (heating), on the other side of condenser (cooling), when one end of the heat pipe heat absorption liquid evaporation vaporization of the liquid core, steam under tiny differential pressure gives off heat flow to the other end condense into liquid, liquid along the porous material by the effect of capillary force flow back to the evaporator.
So not himself, and the heat from one end of the heat pipe to the other side.
