Description
Technical field
The present invention relates to a kind of heat pipe, especially relate to a kind of production technology of copper heat pipe with high serrated fins.
Background technology
The phase-change heat transfer Manifold technology is a new and high technology that unexpectedly develops mutually in the world, has a wide range of applications at aspects such as energy-saving and environmental protection, temperature uniforming heat radiations.Along with developing rapidly of economy, the contradiction of the energy and environmental protection, with new and high technology open up energy saving environmental protection product, hatching is converted into scientific and technological achievement, operates modern enterprise with new and high technology, not only has the market competitiveness, and meets the needs of Chinese national economy development.
Heat pipe on domestic market mostly adopts the metal pipes such as simple copper, aluminium, iron and steel, or is fixed on the excircle of light pipe with expand tube, welding fin.The shortcoming of above-mentioned this heat pipe is that radiating efficiency is low, and manufacturing cost is high.Copper heat pipe with high serrated fins is a kind of heat pipe, is provided with the fins of high teeth that helical form is wound around body on the heat pipe outer surface periphery, can effectively increase heat transfer area, and this product needs a large amount of uses in all kinds of heat exchangers such as China's energy, power, chemical industry, refrigeration.The patent No. of Zhejiang grand copper industry of heap of stone Co., Ltd application is " manufacture craft of copper tube with fins of high teeth " patent of 2004100671591, is exactly a kind of innovation that copper tube with fins of high teeth is produced.On the basis of the manufacture craft of fins of high teeth pipe, we form many, well-regulated grooves parallel with tubing at the inwall of fins of high teeth pipe, play the tube core effect of heat pipe; In addition, adopt special processing technology, make the sealing two ends of heat pipe and shell be structure as a whole.
Summary of the invention
The object of the invention is to the problem for above-mentioned heat pipe, the production technology of the more rational copper heat pipe with high serrated fins of a kind of design is provided.
Principle:
The High Efficiency Thermal exchange capacity absorption of fins of high teeth heat pipe dependence fin and release heat and foreign medium exchange, because the heated liquid in pipe under vacuum state easily produces vaporization, the saturated vapor of having vaporized flows to cold junction (the copper pipe other end), forms liquid after heat is emitted in cold junction (the copper pipe other end) condensation and get back to the hot junction and continue the heat absorption vaporization under the effect of suction pipe inner wall trench capillary force.
In order to achieve the above object, the structure of copper heat pipe with high serrated fins product of the present invention mainly is comprised of copper and the seamless female pipe of copper alloy, be provided with the fins of high teeth that helical form is wound around body on the periphery of seamless female pipe, fins of high teeth and seamless female pipe are structure as a whole, described inside pipe wall have many with the pipe parallel, well-regulated groove, rotation press closing is adopted at the copper pipe two ends, keeps higher negative pressure state in copper pipe, injects certain quantity of fluid (distilled water) in pipe.
Production technology of the present invention is: select female pipe-fins of high teeth and inner wall trench one-shot forming-two ends spinning closing-in-injected media-thermal exhaust-rotation press closing-finished product simultaneously.
Technological process of the present invention is:
1, select female pipe.
At first to select the seamless female pipe of the measured copper of matter or copper alloy.
2, fins of high teeth and internal thread one-shot forming simultaneously.
(1) fins of high teeth moulding.The steps include: to cut-revolve and roll just extruding-spinning extruding formation high wing-finishing wing shape-moulding.Rolling working portion is comprised of incision stage, rolling sequence and finishing stages three part, the incision stage: this stage copper pipe contacts beginning with roll, and along with roller rotational is cut copper pipe gradually, blade diameter increases gradually, incision copper pipe tube wall finishes to the thick finished product thickness that is reduced to of wing endwall; Rolling sequence: stop grooving at this stage blade, but by the increase of blade thickness and the change of shape, fin is processed on thickness, with this understanding, the master metal of compressing on the fin thickness direction will flow to the wing top, and fin height is increased; The finishing stage: by after above-mentioned two stages, its section configuration and size formalize substantially, at last by several finishing blades, make the product section obtain just advising when copper pipe.
(2) inner wall trench moulding.The roll that is comprised of three groups of blades revolves to roll to tube surfaces and forms, be provided with a steel core bar as support at the tubing inner core, be processed into groove on the surface of this steel core bar, the copper pipe inwall is subject to the effect generation spinning of roll-force when copper pipe is rolling, pipe material inner wall its internal surface of pipe under the groove supporting role on steel core bar surface is spun the removing from mould groove, and the degree of depth of groove, shape and a number are controlled by the groove shape of core bar.
3, spinning closing-in.After the one-shot forming simultaneously of fins of high teeth and inside pipe wall groove, qualified through initial test, enter the spinning closing-in operation, wherein an end seals fully, and the other end is reserved Φ 3mm hole as water filling port.
4, water filling.Inject approximately 30% distilled water of shell inner chamber from reserving aperture (water filling port) in shell.
5, thermal exhaust.First with rubber blanket, water filling port is sealed, the package closure end is inserted in oil bath pan (oil temperature is controlled at 130 ℃ ± 2 ℃), make the distilled water in shell become steam fully.After heating 2min, remove the rubber blanket of water filling port, steam is discharged from water filling port.
6, rotation press closing.(this moment, overpressure was between 15MPa～17MPa), seal water filling port (under normal temperature, intraductal pressure is being about 0.02MPa) with the spinning tube clipper rapidly after the steam 1min that gets rid of.
7, finishing-check-finished product.The burr that produces when taking out shell two ends spinning carries out air-tightness and detects, and sends into after the assay was approved finished room.
The present invention compared with prior art has following obvious advantage and innovation: (1) product of the present invention adopts heat pipe principle to add fins of high teeth, has a heat exchanger effectiveness high, and (2) inner surface is processed into the effect that groove has increased capillary force; (3) the present invention adopts heating decompression method, and production technology is simple, is fit to industrialization production (4) and adopts the spinning mode to seal, and sealing is structure as a whole with shell, and handsome in appearance, air-tightness is good; (5) product rigidity of the present invention is strong, and anti-seismic performance is good.
The present invention is applicable to the fields such as electric power, the energy, chemical industry, communications and transportation.
The present invention is described in further detail below in conjunction with the drawings and the specific embodiments.
