Technical field.
Background technology
It, can be adjoint in evolution as electronic component gradually develops to micromation, high power, high-performance direction
Higher heat flow density, heat dissipation problem is increasingly becoming the bottleneck problem for restricting the development of high integration electronic component.Flat-plate heat pipe
Due to its high thermal conductivity and good uniform temperature, can the electric heat source of high heat flux density be shifted into diffusion rapidly, meet electricity
Sub- equipment is increasingly becoming and researchs and solves high-power equipment surface and dissipate to requirements such as the compactedness, reliability, flexibility of radiator
The splendid selection of heat problem.
Common flat-plate heat pipe is made of upper and lower two pieces of metal cover boards, and silk screen, agglomerated powder are often laid in the inner surface of cover board
The wick structures such as end, the thermal conductivity of this wick structure is very low compared to the thermal conductivity of metal cover board, is heat pipe thermal resistance
One of important component leverages the heat transfer property of heat pipe.Moreover, for flat-plate heat pipe, there are still liquid flowings to hinder
The problems such as power is big, steam channel size is big, volume is big, weight is heavy, manufacturing process is complicated, poor sealing.
The content of the invention
Goal of the invention：In order to overcome the deficiencies in the prior art, the present invention provides a kind of based on carbon nano pipe array
Liquid-sucking core support column integral structure flat-plate heat pipe, have the characteristics that thermal conductivity is high, small, light-weight, can both ensure to put down
The heat transfer property of plate heat pipe can reach mechanical strength security during heat pipe operation again.
Technical solution：To achieve the above object, the technical solution adopted by the present invention is：
A kind of liquid-sucking core support column integral structure flat-plate heat pipe based on carbon nano pipe array, including upper metal cover board, under
Metal cover board and the upper and lower metal cover board liquid-sucking core support column integral structure generated respectively on the inside of upper and lower metal cover board；
Wherein, closed cavity is formed by edge seal between the upper and lower metal cover board, and it is closed after vacuumizing

The thin layer carbon nanotubes of upper growth and the vertical carbon nanotubes of several continued growths in thin layer carbon nanotubes specific region, two
Person respectively constitutes metal cover board capillary wick and upper metal cover board support column；The lower metal cover board liquid-sucking core support column is integrally tied
Structure equally includes receiving as the thin layer carbon nanotubes of lower metal cover board capillary wick and the vertical carbon as lower metal cover board support column
Mitron；The upper metal cover board support column is staggered with lower metal cover board support column, forms the liquid-sucking core with fork row's form
Support column integral structure.
Preferably, the thin layer carbon nanotubes and vertical carbon nanotubes are integrally formed.
Preferably, the airtight cavity one side that the upper metal cover board, lower metal cover board are formed is provided with filling liquid pipe.
Preferably, the upper metal cover board, the material of lower metal cover board select copper, and thickness is 0.5mm, length, width
Degree is respectively 55mm, 50mm.
Preferably, the thickness of the thin layer carbon nanotubes is 50 μm；The thickness of the preferred carbon nanotubes support column of the theoretical analysis
It spends for 0.5mm, a diameter of 5mm, spacing 10mm between two centers of circle.
The operation principle of the present invention is：Heat enters the bottom of capillary wick by the evaporator section metal cover board of heat pipe,
The high-termal conductivity of vertical carbon nanotubes causes heat to pass to capillary wicking surface rapidly；Since vertical carbon nanotube diameter only has nanometer
Grade, growing high density are equivalent to the liquid sucting core structure of a fine conduit, have very high capillary force, can be working medium edge
It larger surface tiling to open, makes to be soaked in the liquid heat absorption evaporation in capillary structure rapidly；With evaporator section steam increasingly
More, steam will be transferred to condensation segment from evaporator section under the action of steam pressure difference；Condensation segment metal cover board is in contact with low-temperature receiver, temperature
It spends relatively low, the hot steam of arrival herein is made to be condensed into liquid and is entered in capillary wick, condensation release heat will be transferred to low-temperature receiver.It is perpendicular
The liquid that the capillary wick that straight carbon nanotubes is formed can provide enough capillary forces and make to accumulate in capillary wick is back to evaporator section,
Also some liquid reflux channel provided by carbon nanotubes support column returns to evaporator section, shortens liquid return flow path.
So circulation is gone down, heat is constantly transferred to condensation segment from evaporator section.
Advantageous effect：A kind of liquid-sucking core support column integral structure tablet heat based on carbon nano pipe array provided by the invention
Pipe, compared with the prior art, has the following advantages：
(1) growing high density and nano-grade size that vertical carbon nanotubes has are equivalent to the suction of a fine conduit
Wick-containing structure has very high capillary force, and when liquid flowing resistance is smaller, can provide enough capillary forces makes to accumulate in hair
Condensed fluid in thin core is back to evaporator section, and also some liquid provided by vertical carbon nanotubes support column flows back logical
Road returns to evaporator section, shortens liquid return flow path；
(2) high-termal conductivity possessed by vertical carbon nanotubes, solves the problems, such as that thermal conductivity is low in common wick structure,
So that the heat being passed to from metal cover board passes to rapidly capillary wicking surface by liquid evaporation, the heat transfer property of heat pipe is enhanced, greatly
The big thermal conductivity for improving heat pipe；
(3) liquid-sucking core and support column arrangement described in are the integrated molding based on vertical carbon nano pipe array, easy to process
It makes.Upper and lower metal cover board is using edge seal, good airproof performance；Since the intensity of vertical carbon nanotubes is high so that the support column
Structure is under rational structure design, the vapor space for the thinner and enough supporting ＆ stablizing that can be designed, and effectively prevents that tablet is warm
Pipe deformation collapses problem, and the very light in weight of vertical carbon nanotubes so that weight is lighter under flat-plate heat pipe same volume, therefore
The lighter ultra-thin panel heat pipe of volume smaller, weight can be produced；
(4) due to liquid working substance can by the vertical carbon nanotubes capillary wick on wall surface provide enough capillary forces and
The in vivo carbon nanotubes support column return flow line of chamber returns to evaporating surface, therefore heat pipe is carried out random angle placement, to liquid
Back-flow velocity influences all very littles, adds the application flexibility of heat pipe.
