Pumping source and gain media, Condensation photovoltaic battery of photovoltaic art of the great-power solid laser in domain etc., always all towards
High speed, integrated, miniaturization path are fast-developing.At the same time, an inevitable problem occurs immediately, that is, run
When heating problem, it result in component fluctuation of service, or even burn out, therefore be said from thermal conduction study angle, and this kind of device can unite
It is classified as high heat flux planar heating body.In addition, this kind of component is in use, mounting means may level or upright two
Kind, with the development of technology, also there is the occasion of many applying electronic chips, due to special circumstances such as position is narrow and small, carrier limitations
Under, upright installation is employed, absolute quantity is also very big, but due to historical reasons, problem few to upright installation radiating research
It is very prominent, into one of thermal technology scientific and technological circle study hotspot.
Although above-mentioned component function is different, there are three important similar features：One is non-heat flow density
Chang Gao, two is three dual-purposes anyhow with planar profile.
When heat flow density high originates from the operation of high heat flux planar heating body, because Energy Efficient conversion efficiency is low or energy
Input is excessive, so that occur high heat flux, such as mean heat flux of IC chip in the minimum volume of planar heating body or area
Density is up to 300~500W/m2, LED is up to 300W/m2, TR components are up to 150W/m2, gain media is up to 100W/m2、1000
Times Condensation photovoltaic battery is up to 500W/m2.Further, since the difference of high heat flux planar heating body internal microstructure operation,
Can also there is heat flow density exception high point.
From heat transfer theory, above-mentioned two height will make planar heating body bulk temperature too high and temperature is uneven, be also actually
So.
Research shows, as microelectronics, opto-electronic device, operating temperature all Constraineds of planar heating body, in general,
The operating temperature that it is allowed is between 75~120 DEG C, and different types of planar heating body has different permissible values.When temperature exceedes
During permissible value, the service behaviour of planar heating body and life-span will decline to a great extent, or even burn.Therefore, to enable planar heating body
Enough good, stabilizations, safe operation, carry out good cooling most crucial to it.
Due to by the limitations such as installation site narrow and small, permission operating temperature and uniform temperature, the radiating dress of planar heating body configuration
Put and must be fulfilled for following technical requirements：Planar heat transfer, excellent heat transfer properties, uniform temperature are good, area occupied is small, area of dissipation is big,
Simple and reliable, dual-purpose anyhow.It is required that at a relatively high.
Heat pipe is referred to as the superconductor of heat, and with excellent heat transfer properties, non-power consumption, takes up room and area is small, be
The advantages of uniting simple and reliable.Therefore, scientific worker is directed to such high heat flux planar heating body, numerous studies are carried out,
Various so-called plane heat pipes with contact plane or flat-plate heat pipe are developed, is used to solve the problems, such as its cooling.

Fill, avoid Steric clashes from providing conveniently, also flowed back beneficial to working medium.The pulsation passage is parallel to each other, the sky in one end and hot junction
Chambers of the heart body is connected, and the other end is interconnected, on the one hand, is realized the mass transfer with hot junction working medium by liquid-sucking core, on the other hand, can be made
Each pulsation passage communication with one another in parallel of pulsation cold end, adaptive balance so that working medium distribution is more average is independent in the height direction
Condensate liquid in conduit can with uniform and stable entrance hot junction, both beneficial to heat pipe it is stable and also beneficial to working medium in passage of pulsing
Evenly distribute.When upper cover plate, lower cover are vertically arranged, hot junction upper and lower cover plates barycenter vertical line is not conllinear, can cause on hot junction
Lower plane spatially misplaces, and can improve pulsation cold end position for upright cooling situation, it is to avoid working medium floods pulsation cold end
