Description
Technical field：This utility model is related to a kind of heat pipe, specially plough groove type compound needle fin structure flat board Thiele tube.
Background technology：
With developing rapidly for electronic technology, the high frequency of microelectronic component, high speed, and integrated circuit it is intensive and miniature
Change so that the power consumption of electronic chip is increased dramatically, and result in high heat flow density.The hot spot effect of integrated circuit can not only contract
The service life of short electronic device, can also affect the photoelectric transformation efficiency of its normal working performance, LED chip to there was only 20%-
30%, most energy is scattered and disappeared in the form of heat, and it is restriction electronic chip and collection that how quick heat radiating reduces hot spot effect
Into the major reason of circuit development.
Realize that by the phase transformation of working medium the flat-plate heat pipe for conducting heat has compact conformation, excellent uniform temperature, high leads
Hot and easy to attach the advantages of, meet that chip is compact to heat abstractor, reliable, flexible well, efficiently and need not keep in repair
Deng requirement.So, flat-plate heat pipe technology will become the main flow of future microelectronics components and parts and its cooling system, and flat-plate heat pipe
Further enhanced heat transfer performance is then the key technology for affecting chip integration development.
Flat-plate heat pipe performance quality it is critical only that the liquid sucting core structure of inside, and the liquid sucting core structure of current flat-plate heat pipe is main
There is two big class of sintered type and plough groove type.Sintered type wick is the metal for sintering one layer of micro/nano level in flat-plate heat pipe internal face
Powder, the passage for providing working medium backflow with this and capillary force, but sintered type wick stability is inadequate, easy to fall off, working medium backflow resistance
Power is big and overall heavier.Plough groove type wick mainly processes the conduit of certain cross sectional shape in heat pipe inner wall face, passes through
Minute groove provides the capillary force of liquid working substance backflow.But there is certain, upper and lower two plate in such plough groove type wick
Separate during direct splicing each conduit can enable interfacial shear force increase impact heat transfer row；Though splice after one framework of middle pad
Larger interfacial shear force is avoided that, but can be flattened under larger vacuum；And between upper and lower plates, add support column then can
Increase loaded down with trivial details technique, thicken tube wall and then run counter to the light principle of heat pipe.And these liquid sucting core structures are mainly designed to
Consider to provide capillary force, therefore require that design meets the suction of upper and lower plates working condition according to flat-plate heat pipe operation principle and portability
Wick-containing structure is the development trend of flat-plate heat pipe.
Utility model content
The purpose of this utility model be solve the problems, such as background technology in mention, the groundwork for analyzing each section of heat pipe is former
Reason, while strong capillary is ensured, lifts the boiling performance of evaporator section and the steam cooling of heat pipe startability and condensation segment
Performance, pin fin structure can not only be played a supporting role and be reduced interfacial shear force and be conducive to upper plate condensation water quick backflow
Drop to lower plate and form circulation, make the heat transfer property of heat pipe mention raising.
The technical solution of the utility model is realized as follows：
A kind of novel flat-plate Thiele tube, including a red copper upper plate, a red copper lower plate and a fluid injection exhaust tube composition,
It is evaporator section that the upper plate is condensation segment, lower plate, between the two referred to as adiabatic section, and the upper and lower plates internal face is machined with plough groove type
Compound needle fin structure, the plough groove type compound needle fin structure are that upper plate condensation segment is plough groove type pin wing array structure, lower plate evaporation
Section is plough groove type pin fin structure.
The plough groove type compound needle fin structure is obtained in the internal face of upper and lower plates by way of removing material.
The cross sectional shape of the groove structure is triangle, rectangle or trapezoidal.
The groove structure be plough groove type compound needle fin structure, upper plate condensation segment be plough groove type pin wing array structure, lower plate
Evaporator section is plough groove type pin fin structure.
The height of the pin fin structure is not more than the groove structure, and the pin fin structure is made to playing to support at top
With.
The size of the plough groove type compound needle fin structure and cross sectional shape can be determined by processing method.
The beneficial effects of the utility model are：
The operation principle of flat board Thiele tube is taken into full account, respectively according to upper plate condensation segment with on traditional groove structure
Plate evaporator section devises pin wing array structure and pin fin structure.Change compared with strong capillary and increase ensureing that conventional trench structures are provided
While hotlist area, the pin fin structure of lower plate boiling section further increases heat exchange area, and provides more effectively vaporizations
Core number enables heat pipe to start faster；The pin wing array structure of upper plate condensation segment equally can further increase heat-transfer surface
Product, and while thinning thickness of liquid film reduces heat transfer resistance, a drain can be played a part of to liquid working substance, accelerate
The backflow of drop；The effect that a support can be played to top again of upper plate and lower plate pin fin structure, so that increase tube wall strength.
Increase its intensity by above while acting on stiffened flat plate adopting heat pipes for heat transfer ability, hyundai electronicses radiating is met with this
Require.
