Abstract	本发明公开了梯度润湿性环路热管，包括吸液芯及热管本体，热管本体内部设有蒸发室及环形的散热通道，蒸发室与散热通道连通，吸液芯容置于蒸发室内，蒸发室与散热通道内容置有工作流体，散热通道具有绝热段及冷凝段，沿工作流体的流动方向，将散热通道的内表面设置为与工作流体之间的接触角逐渐减小。本发明中的散热通道与蒸发室形成供工作流体循环流动的环形回路，工作流体在经过绝热段时气化，并在冷凝段处冷凝放热，降低工作流体的温度，工作流体在吸液芯的毛细力及散热通道内表面产生的梯度力作用下在环形回路内循环流动，循环效率较高，并能带走蒸发室内吸收的热源热量，提高环路热管的散热效率。
Other Abstract	The invention discloses a gradient wettability loop heat pipe. A liquid absorbing core and a heat pipe body are included. An evaporation chamber and an annular heat dissipation channel are arranged inthe heat pipe body. The evaporation chamber communicates with the heat dissipation channel. The liquid absorbing core is contained in the evaporation chamber. Work fluid is contained in the evaporation chamber and the heat dissipation channel. The heat dissipation channel is provided with a heat insulation section and a condensation section, and in the work fluid flowing direction, the inner surface of the heat dissipation channel is set in the manner that the contact angle between the inner surface of the heat dissipation channel and the work fluid is gradually reduced. An annular loop for work fluid cyclic flowing is formed between the heat dissipation channel and the evaporation chamber in the gradient wettability loop heat pipe, the work fluid is gasified when passing through the heatinsulation section, condensation heat releasing is conducted at the position of the condensation section, and the temperature of the work fluid is reduced. The work fluid cyclically flows in the annular loop under the action of capillary force of the liquid absorbing core and gradient force generated on the inner surface of the heat dissipation channel, the circulation efficiency is high, heat source heat absorbed in the evaporation chamber can be brought away, and the heat dissipation efficiency of the loop heat pipe is improved.
