Description
Technical field
The present invention relates to a kind of automatically cleaning heat pipe with super hydrophilic liquid-sucking core, belong to technical field of heat exchange.
Background technology
Heat pipe is a kind of element relying on the phase transformation of therein hydraulic fluid to realize heat transmission, and it utilizes the evaporation of liquid and condensation that heat is transmitted fast.It can by very little cross-sectional area long-distance sand transport heat without the need to additionaling power simultaneously.Just because of the heat transfer property that heat pipe self is excellent, heat pipe is used widely in fields such as solar heating, Electronic cooling, chemical, Aero-Space.
Heat pipe mainly relies on liquid-sucking core in pipe to obtain capillary force and realizes heat transmission, and the heat transfer medium backflow that liquid-sucking core orders about directly affects heat transfer efficiency, is therefore necessary to improve liquid-sucking core further, realizes efficient heat transfer.
For the heat pipe be chronically exposed in air, its outer surface is easy to attract dust, which increases heat pipe heating surface thermal resistance, reduces heat transfer property.Clean surface impurity needs at substantial human and material resources simultaneously.
Summary of the invention
Given this, be necessary to provide a kind of automatically cleaning heat pipe realizing efficient heat transfer.
For achieving the above object, the technical scheme that the present invention takes is as follows.
There is an automatically cleaning heat pipe for super hydrophilic liquid-sucking core, comprise shell, super hydrophilic liquid-sucking core, based superhydrophobic thin films.Described shell material is copper, stainless steel etc.; Described shell is closed cavity; Containing super hydrophilic liquid-sucking core and heat transfer medium in described closed cavity; Described super hydrophilic liquid-sucking core overlays on the inner surface of closed cavity; Described super hydrophilic liquid-sucking core comprises liquid-sucking core and super-hydrophilic film two parts; Described super hydrophilic liquid-sucking core is silk screen liquid-sucking core; Described super-hydrophilic film is on silk screen liquid-sucking core surface; Described super-hydrophilic film surface roughness thickness is between 50 ~ 500nm; Described super-hydrophilic film surface roughness top diameter is between 1 ~ 200nm; Described super-hydrophilic film surface roughness top spacing is between 10 ~ 100nm.Described based superhydrophobic thin films overlays on the outer surface of closed cavity; Described based superhydrophobic thin films thickness is between 50 ~ 500nm; Described based superhydrophobic thin films is based on materials such as high-thermal conductive metal, metal oxide, graphite.
Beneficial effect of the present invention: described super-hydrophilic film, constructs the surface area and capillarity that add liquid-sucking core by nanometer coarse structure, thus promote the evaporation of heat pipe evaporator section, the condensation of condensation segment and liquid backflow, improve heat transfer property.Described based superhydrophobic thin films, its surface has good anti-adhesive properties, and surface dirt can be removed by rain drop erosion effect, thus can realize the self-cleaning function of tube surface.
Accompanying drawing explanation
Fig. 1 is the automatically cleaning heat pipe structure schematic diagram with super hydrophilic liquid-sucking core.
In figure, 1 is shell; 2 is super hydrophilic liquid-sucking core; 3 is based superhydrophobic thin films; 4 is evaporator section; 5 is condensation segment.
Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment of the invention is described further.
Shell 1 material is copper, stainless steel etc.
Silk screen liquid-sucking core is prepared at shell 1 inner surface.
The method such as chemical bath deposition, electrochemical deposition is adopted to construct super-hydrophilic film after clearing up liquid-sucking core surface.For increasing surface wettability, this film is to have the nanostructured of obvious roughness.
Pour into suitable heat transfer medium after being vacuumized by shell 1, then close the mouth of pipe, form enclosure space.
The method such as chemical bath deposition, magnetron sputtering constructing super-drainage film 3 is adopted after shell 1 outer surface is cleared up.For reducing thermal resistance, this film is based on high-thermal conductive metal and the material such as metal oxide, graphite.
When evaporator section in heat pipe 4 is heated, the heat transferring medium in heat pipe is at super hydrophilic liquid-sucking core surface rapid vaporization, and steam flows to condensation segment 5 under small pressure differential, and releases heat.Now drop merges in the surperficial rapid condensation of the super hydrophilic liquid-sucking core 2 of condensation segment, and by capillarity, drop is back to evaporator section 4.By this Rapid Circulation, heat can be come by conduction continuously.
By constructing of liquid-sucking core surface super hydrophilic film, add surface area, promote the transfer rate of evaporator section heat.
By constructing of super hydrophilic liquid-sucking core in heat pipe, add surface wettability, promote that liquid is in the rapid condensation fusion of inwall and the backflow to evaporator section.
The based superhydrophobic thin films of heat pipe outer surface can reduce drop in tube surface wetability, and drop exists with pearl form at tube surface, can speed away and take away surface dirt, realizing self-cleaning performance.
