Description
Technical field
The present invention relates under a kind of heat pipe integrated preparation technology and interface arrangement, especially normal temperature, can, to all size heat pipe, vacuumize, fill the integration system such as working medium, sealing standby.Belong to heat pipe preparing technical field.
Background technology
In numerous heat transfers and case, heat pipe is known one of the most effective heat transfer element, and it can transmit amount of heat by its very little sectional area and at a distance without additionaling power.Since the seventies, hot pipe technique develop rapidly, scientific research institution, institution of higher learning, company and the factories and miness of various countries have been carried out many-sided exploitation, application study, and the hot pipe technique exchange activity of international, area and various countries self is day by day frequent.
Along with the fast development of electronics and information industry, the electronic component disposal abilities such as central processing unit are strengthened day by day, the heat producing all increases with it, fin cannot meet radiating requirements gradually in conjunction with the heat radiation module of fan, especially notebook computer, at present heat pipe is a quilt be widely used in the conducting heat critical elements of use.Heat pipe can be considered that being one has high heat conducting passive heat transfer element, and because inner two phase flow heat passes mechanism, the heat-transfer capability that makes heat pipe is the more than hundreds of times of same size copper metal.While utilizing heat pipe as hot transmitter, have advantages of that reflection is rapid and thermal resistance is little.Therefore can coordinate the use of heat pipe or its derived product to develop various high-performance heat radiation module, be applicable to solving current various electronic product because of the derivative heat dissipation problem of performance boost.
Heat pipe package mainly comprises carbon steel, aluminium and aluminium alloy, copper and copper alloy.Sealing for carbon steel heat pipe is closed up mainly by under high-temperature heating, and spinning closing-in also carries out electric welding soldering and sealing, and it is ripe that equipment and processing technology have been tending towards, but carbon steel heat pipe has the weak points such as highly energy-consuming, heat transfer efficiency be low, and development approaches stagnates.
And for the heat pipe of the non-carbon steel class such as copper, aluminium alloy material, because it has extremely low thermal resistance and good heat-transfer character, can be made into high-efficiency heat exchanger, high efficiente callback middle-low temperature heat, gradually by market is favored.
In general, Cryo Heat Tube material is mainly taking copper and aluminium matter as main, and copper on market-Water Heat Pipes application is comparatively extensive.Although copper-Water Heat Pipes has good heat transfer property, can meet the demand of middle Low Temperature Thermal transmission field, for remaining high of domestic and international copper price, its preparation cost has also restricted the development space of copper-Water Heat Pipes.
Heat pipe vacuumize, fill heat transfer medium, also be technique more crucial in heat pipe preparation process, wherein widely used is boiling and exhaust method, but this method is only only applicable to the heat pipe specification preparation taking water as medium such as copper-water, water steel heat pipe, copper heat-pipe working medium is water, adopt boiling process can solve topping up and vacuumize two key technology difficult problems, seal by spinning friction-welding technique.And for the organic efficient such as acetone, methyl alcohol heat transfer medium class heat pipe, use the method not only to waste medium, and improve production cost, also easy atmosphere pollution, neither environmental protection is also dangerous.
Single preparation with regard to acetone working medium class heat pipe, adopts a kind of cooled with liquid nitrogen method, after the heat pipe of an end closure fills medium-acetone, is placed on cooled with liquid nitrogen to solid state, then it is vacuumized, and last pressure welding completes heat pipe preparation.This kind of method, operation is various, and will follow consumption liquid nitrogen, and cost is high, can not actively apply.
Aluminum and aluminum alloy mateial, although thermal conductivity is slightly poorer than copper material, its abundant raw materials, reserves are large, cheap etc., along with hot transmission radiating area research not very deeply, day by day become the optimal selection that substitutes copper heat pipe.But be but faced with in topping up situation, be difficult to that its aluminium matter heat pipe is carried out to effectively sealing and wait technical barrier.
It is very high that aluminothermy pipe requires preparation technology.Especially the requirement of sealing process is tighter.Especially the requirement of sealing process is tighter.At present existing multiple mouth-sealing method, wherein a kind of method be by cold welding tong by topping up heat pipe pinched-off seal, this mouth-sealing method is more fragile, cannot stand collision impact, in the time that in pipe, operating pressure is slightly large, the mouth of pipe may be broken through.As cold welding tong, definitely reliable in when sealing, particularly, in manual pinch off situation, in pinch off moment, there is a little shake, will cause sealing defect but heat pipe is scrapped.
The present invention, for this technical bottleneck, proposes a kind of realization and vacuumizes, fills working medium, seals integrated interface arrangement, practical.Interface arrangement volume of the present invention is little, easily produces, flexible for installation, simple to operate, utilizes this device to produce heat pipe, without the operation such as pressing, welding, improves heat pipe production efficiency and yield rate, and automaticity is high, therefore has huge economic and social profit.
