The inner grooved copper tube is simple in structure and small in bottom wall thickness and rack height, can effectively reduce flow resistance in the tube, guarantees circulation of coolants in the tube, improves heat exchanging efficiency, saves materials and reduces production cost.
Description
Technical field
The present invention relates to a kind of inner screw thread copper pipe, relate in particular to the inner screw thread copper pipe that in the industries such as a kind of micro computer, mobile phone and LED, the condensation heat abstractor is used.
Background technology
Riffled tube is as a kind of high-performance heat transfer components, the heat radiation aspect that has been widely used in the industries such as micro computer, LED, mobile phone, existing inner screw thread copper pipe generally has that diapire is thick, tooth depth is higher and the characteristics such as consumable quantity is large, not only causes the waste of material, and has increased production cost.
Along with scientific and technical development, micro computer industry (notebook computer, panel computer, mobile phone) product structure is towards more compact, and processor is towards the high-power future development of high speed more.Therefore, the future developments such as thick to thin diapire, the low tooth depth of inner screw thread copper pipe, energy-conserving and environment-protective have become inevitable trend.
Summary of the invention
The object of the present invention is to provide a kind of inner screw thread copper pipe, the pipe thickness of moulding is thin, and production cost is low, and heat conductivility is good.
For reaching this purpose, the present invention by the following technical solutions:
The invention provides a kind of inner screw thread copper pipe, comprise body, have the spiral helicine tooth bar distributed along even circumferential on the inwall of described body, the thick T of the diapire of described tooth bar is 0.1-0.15mm, and the tooth depth H of described tooth bar is 0.1-0.12mm.
As preferred version of the present invention, the number of teeth n of described tooth bar is 60-120.
As preferred version of the present invention, the helixangleβ of described tooth bar is 0-5 °.
As the present invention further optimization scheme, the helixangleβ of described tooth bar is preferably 0 °.
As preferred version of the present invention, the addendum angle α of described tooth bar is 5-25 °.
As the present invention further optimization scheme, the addendum angle α of described tooth bar is preferably 5-10 °.
As preferred version of the present invention, the tooth top width r1 of described tooth bar is 0.03mm, and the tooth bottom width r2 of described tooth bar is 0.02mm.
As preferred version of the present invention, the gear tip clearance of described tooth bar is apart from being 0.09 ± 0.02mm, and at the bottom of the tooth of described tooth bar, spacing C2 is 0.05 ± 0.02mm.
As preferred version of the present invention, the outer tube surface roughness of described body is 0.02Ra, and the external diameter of described body is 6mm, and the thickness of pipe wall of described body is 0.15mm.
Beneficial effect of the present invention is: inner screw thread copper pipe provided by the invention, simple in structure, diapire thick thinner, tooth depth is lower, not only effectively reduce flow resistance in pipe, guaranteed the circulation of refrigerant in tubing inside, improved rate of heat exchange, and saved material, reduced production cost.
The accompanying drawing explanation
Fig. 1 is the structural representation of the inner screw thread copper pipe that provides of embodiment of the present invention;
Fig. 2 is the structure enlarged diagram at the A place shown in Fig. 1.
Wherein:
1, body; 2, tooth bar.
The specific embodiment
Further illustrate technical scheme of the present invention below in conjunction with accompanying drawing and by the specific embodiment.
As depicted in figs. 1 and 2, a kind of inner screw thread copper pipe that present embodiment provides, comprise body 1, and the outer tube surface roughness of body 1 is 0.02Ra, and the external diameter of body 1 is 6mm, and the thickness of pipe wall of body 1 is 0.15mm.
Have the spiral helicine tooth bar 2 distributed along even circumferential on the inwall of body 1, and the rotation direction of tooth bar 2 is left-handed, the thick T of the diapire of tooth bar 2 is 0.1-0.15mm, and the tooth depth H of tooth bar 2 is 0.1-0.12mm.With prior art, compare, this inner screw thread copper pipe has reduced the thick and tooth depth of diapire, not only effectively reduces flow resistance in pipe, has guaranteed the circulation of refrigerant in tubing inside, has improved rate of heat exchange, and has saved material, has reduced production cost.
Preferred version as present embodiment, the number of teeth n of tooth bar 2 is 60-120, effectively increased the circulation internal surface area in the pipe, reduced flow resistance, improved heat transfer property, in the situation that internal surface area is fixing, can reasonably set the number of tooth bar 2, higher heat transfer efficiency makes this inner screw thread copper pipe be more suitable for being applied in the condensation heat abstractor of the industries such as micro computer, mobile phone and LED.
As the preferred version of present embodiment, the helixangleβ of tooth bar 2 is 0-5 °, and helical angle is larger, the processing and forming difficulty is larger, and production efficiency is low, in the present embodiment, the helixangleβ of tooth bar 2 is preferably 0 °, that is to say that tooth bar 2 is the spur gear structure, manufactures conveniently.
Preferred version as present embodiment, the addendum angle α of tooth bar 2 is 5-25 °, the preferable range 5-10 ° of the addendum angle α of tooth bar 2, the main cause of selecting this scope is that addendum angle is larger, although easy processing and forming, the cast substance is larger, the waste material, in the pipe, circulation area reduces simultaneously, and pressure drop is large, affects heat exchange property.
As the preferred version of present embodiment, the tooth top width r1 of tooth bar 2 is 0.03mm, and the tooth bottom width r2 of tooth bar 2 is 0.02mm.
As the preferred version of present embodiment, the gear tip clearance of tooth bar 2 is 0.09 ± 0.02mm apart from C1, and at the bottom of the tooth of tooth bar 2, spacing C2 is 0.05 ± 0.02mm.
Inner screw thread copper pipe provided by the invention, diapire thick thinner, tooth depth is lower, simple in structure, not only can effectively reduce flow resistance in pipe, guarantees the circulation of refrigerant in tubing inside, improves rate of heat exchange, and can save material, reduce production costs.
Abovely in conjunction with the specific embodiment, know-why of the present invention has been described.These are described is in order to explain principle of the present invention, and can not be interpreted as by any way limiting the scope of the invention.Explanation based on herein, those skilled in the art does not need to pay performing creative labour can associate other specific embodiment of the present invention, and these modes all will fall within the scope of protection of the present invention.
