Description
Technical field
The utility model is related to electrical cooling field more particularly to a kind of micro heat pipes having nano-pillar.
Background technology
Pulsating heat pipe, age in last century propose by Japanese scholars, the pulsating heat pipe of the prior art be a kind of mechanism it is simple but
The two phase flow Thermal Conduction Equipment of complicated mechanism, it is to vacuumize the capillary of a root long, then will be filled with liquid inside capillary,
If capillary diameter is sufficiently small, steam binding and liquid plug will be intermittently formed in pipe, the liquid when one end of pulsating heat pipe is heated
Carburation by evaporation, steam flow to other end releasing heat under small pressure difference and condense into liquid.Pipe with small pipe diameter and hot and cold side are repeatedly
Bending is to form two primary conditions of pulsating heat pipe, and heat is transmitted by phase transformation and vapour-liquid pulsation.Compared with general heat pipe,
Its is simple in structure, it is not necessary to and liquid-sucking core is not influenced by gravitation, and caliber is small, and heat pipe shape can be arbitrarily bent, and adaptability is good, because
This manufacture, operation and maintenance cost low pulse heat pipe are considered as solution short space high heat-flux and dissipate due to its excellent performance
Most it is hopeful the heat transfer element with future in hot scheme.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, adapt to reality and need, providing one kind having nano-pillar
Micro heat pipe.
In order to realize that the purpose of this utility model, the technical solution adopted in the utility model be：
A kind of micro heat pipe having nano-pillar, including evaporator section, condensation segment are provided between the evaporator section and condensation segment
Condensate return channel and steam channel, the condensate return channel are arranged in steam channel both sides, and the steam channel leans on
Nano-pillar module is set in the channel of nearly condensation segment and in condensation segment.
The length of the heat pipe is less than 3 centimetres, and the width of the heat pipe is less than 1 centimetre, and the heat pipe height is 7 microns.
The heat conducting module of hot spot point is provided on the outside of the evaporator section.
The nano-pillar module is made of a large amount of nano-pillars, and the height of the nano-pillar is 7 microns, between the nano-pillar
Away from being 100 nanometers, the width of the nano-pillar is 150 nanometers.
The beneficial effects of the utility model are：
The design is the cooling for the hot spot in some electronic components, using the cooling scheme of micro heat pipe, in itself
Just there is preferable cooling effect, and this heat pipe for adding nano-pillar in condensation segment has higher heat dissipation effect.

Fig. 4 is the plan view that heat conducting module is added.
Wherein, 1 be heat pipe evaporator section, 2 be condensation segment, and 3 be nano-pillar module, and 4 be steam channel, and 5 be that condensed water returns
Circulation road, 6 be the heat conducting module of hot spot point.
Specific implementation mode
The utility model is further illustrated with reference to the accompanying drawings and examples：
Referring to Fig. 1-4.
The utility model discloses, a kind of micro heat pipe having nano-pillar, including evaporator section 1, condensation segment 2, the evaporation
Condensate return channel 5 and steam channel 4 are provided between section 1 and condensation segment 2, the setting of condensate return channel 5 is being steamed
4 both sides of vapour channel, the steam channel 4 in the channel of condensation segment 2 and are provided with nano-pillar module 3 in condensation segment 2.
The length of the heat pipe is less than 3 centimetres, and the width of the heat pipe is less than 1 centimetre, and the heat pipe height is 7 microns.
1 outside of the evaporator section is provided with the heat conducting module 6 of hot spot point.
The nano-pillar module 3 is made of a large amount of nano-pillars, and the height of the nano-pillar is 7 microns, the nano-pillar
Spacing is 100 nanometers, and the width of the nano-pillar is 150 nanometers.
The use principle of the utility model is summarized as follows：
When the fever end of electronic component is bonded with the evaporator section 1 of heat pipe, the working medium deionized water in heat pipe is steamed by thermal evaporation
Vapour reaches condensation segment 2 by intermediate minitype channel, and adds nano-pillar module 3 in condensation segment 2, due to the presence of nano-pillar
Condensed water is set to be easier to condense between nanostructure, the condensation rate of micro heat pipe is significantly improved, cold after cooling
Condensate has returned to evaporator section under differential pressure action by reflux line, above procedure is repeated, to take away the heat of heat generating spot.By
In the design for adding nano-pillar, there is faster condensation rate, improve radiating efficiency.
The above description is only the embodiments of the present invention, and it does not limit the scope of the patent of the present invention, every
Equivalents made based on the specification and figures of the utility model are applied directly or indirectly in relevant technical field,
It is equally included in the patent within the scope of the utility model.
