Problems solved by technology

When the end of the heat pipe that absorbs heat increases, the evaporation speeds up, and the speed of the liquid decreases due to the backflow resistance, so it cannot quickly replenish the evaporated liquid at the heat-absorbing end, which will easily cause dry burning and damage the heat pipe

Embodiment Construction

[0014] like figure 1 As shown, the heat pipe 10 of the present invention includes a pipe body 12 and a porous capillary structure disposed on the inner wall of the pipe body 12 . Wherein, the pipe body 12 is made of a metal material with good thermal conductivity such as copper, and the cross section of the pipe body 12 shown in the figure is circular. It can be understood that the cross section of the pipe body 12 can also be in other shapes, such as Square, polygonal, oval, etc. In addition, the tube body 12 is also filled with a working liquid (not shown in the figure), and the working liquid generally adopts a liquid with a low boiling point, such as water, alcohol, and the like.

[0015] One end of the heat pipe 10 forms an evaporating section A, and the other end forms a condensing section C, and an insulating section B can be arranged between the two sections according to application requirements. The liquid is used to evaporate the liquid. The insulation section B is...

Abstract

The invention relates to a sintered heat tube, which comprises a metallic tube. Wherein, the inner wall of tube has porous capillary structure formed by sinter powder; the porous capillary structure has several layers along the radius of heat tube, while each layer has several sections along the axle of heat tube; said capillary structure is formed by embedding different powder particles into the tube, using core rod as the control of thickness to be sintered on the inner wall. Said porous capillary structure can realize variable three-dimensional grade porous size and supply lower reflux resistance and improved capillary function, to improve the property of heat tube.

Description

【Technical field】 [0001] The invention relates to the field of heat dissipation, in particular to a sintered heat pipe for transferring heat and a manufacturing method thereof. 【Background technique】 [0002] With the continuous advancement and wide application of large-scale integrated circuit technology, the development of the information industry has advanced by leaps and bounds, and high-frequency and high-speed processors have been continuously introduced. Due to the high-frequency and high-speed operation, the processor generates a lot of heat per unit time. If the heat is not removed in time, the temperature of the processor itself will rise, which will have a great impact on the safety and performance of the system. At present, heat dissipation has become a new generation of high-speed processing. Problems that must be solved when the device is released. [0003] Due to the ever-increasing demand for heat dissipation, new types of heat sinks continue to emerge. The...
