Abstract
The invention discloses a fluted pipe with an external fin structure, which comprises a pipe body, wherein a plurality of external fins are distributed on an outer wall of the pipe body in an array form; the external fins are separated at intervals; flutes are formed in the interval positions; a plurality of internal teeth are arranged at intervals on an inner wall of the pipe body along the axial direction of the pipe body; inner flutes are formed in the interval positions between the internal teeth; an integrated structure is formed by the pipe body, the external fins and the internal teeth; no contact thermal resistance exists between the external fins as well as the internal teeth and the pipe body, so that the heat-conducting property is better; the external fins and the internal teeth are high in strength; the pipe body, the external fins and the internal teeth are integrated and are difficult to fall off; the geometrical shape parameter is easily adjusted; the external fin structure is adopted on the outer surface of the pipe body, so that the area of the outer surface of the pipe body is greatly increased; when air convection flows by the surface of the pipe body, under the stopping function of the external fins, especially under the turbulence function, the heat exchange efficiency is greatly increased; and the fluted structure is formed on the inner surface of the pipe body and the capillary force of the inner surface of the pipe body is greatly increased, so that the pipe body can work as a heat pipe under a powerless condition.
Description
Technical field
The present invention relates to the electronic applications thermal component, relate in particular to a kind of fluted tube with outer fin structure.
Background technology
Along with the progress and the development of producing, the heat flow density of high-power electronic device increases severely, and the heat dissipation problem of electronic equipment becomes a big difficult point that hinders industry development.Seek a kind of radiating element simple in structure, that radiating efficiency is high and become the human target of pursuing in recent years.
Summary of the invention
The objective of the invention is to overcome the shortcoming and defect of prior art, a kind of fluted tube with outer fin structure is provided.The present invention increases the area of outer surface of tube body and inner surface, strengthens steam condensation and convection heat transfer' heat-transfer by convection performance, significantly improves the heat transfer property of body.
The present invention realizes through following technical proposals:
A kind of fluted tube with outer fin structure comprises body, and the outer wall array distribution of body has a plurality of outer fins, space between each outer fin, and the place, space forms conduit; Said inboard wall of tube body is along several internal tooths that axially offer the space of body, and the interval between the internal tooth forms internal channel.
The two ends of said body can be hermetically-sealed constructions, also can be non-hermetically-sealed constructions.Said body, outer fin, the internal tooth structure that is formed in one.
Said outer fin is rectangular, trapezoidal, in V-arrangement or the U-shaped any one.
In rectangular, the trapezoidal and inverted V-shaped of said internal tooth any one.
Compared with prior art, advantage of the present invention and effect are:
(1) there is not thermal contact resistance in body of the present invention, outer fin, the internal tooth structure that is formed in one between outer fin and internal tooth and the body, and heat conductivility is better; Outer fin, internal tooth intensity height, outer fin and internal tooth and body are structure as a whole, difficult drop-off, and its geometric shape parameters is adjusted easily.
(2) the present invention's fin structure outside outer surface of tube body adopts increases the exterior surface area of body greatly; Cross-ventilation is out-of-date from the body surface current, because the barrier effect of outer fin is main with turbulent flow mainly, has improved heat exchange efficiency greatly.
(3) the present invention generates groove structure at inner surface of tube body, increases the area of inner surface, improves heat exchange efficiency; Because groove structure can increase the capillary force of inner surface of tube body, and body can be worked under unpowered situation as heat pipe.
(4) reliable working performance of the present invention, radiating efficiency height, technological means is simple and easy to do.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a cross section structure sketch map of the present invention.
Fig. 3 is the cross section structure sketch map of the trapezoidal outer fin of the present invention.
The specific embodiment
Below in conjunction with specific embodiment the present invention is done further concrete detailed description the in detail.
Embodiment
Like Fig. 1, Fig. 2, shown in Figure 3, the present invention has the fluted tube of outer fin structure, comprises body 3, and the outer wall array distribution of body 3 has a plurality of outer fins 2, space between each outer fin 2, and the place, space forms conduit 1; Said body 3 inwalls are along several internal tooths 4 that axially offer the space of body 3, and the interval between the internal tooth 4 forms internal channel 5.
According to the different radiating requirement, hermetically-sealed construction can be processed in the two ends of said body 3, charges into a certain amount of working medium at body 3 before the sealing, and then vacuumizes and with closed at both ends, make it become the heat pipe that need not to consume energy, and carry out heat exchange work; Two ends like body 3 are unsealed structure, and then liquid can be passed through in body 3 inside, accomplish heat exchange work.
Said body 3, outer fin 2, internal tooth 4 can be integrated formed structures.
Said outer fin 2 can be rectangular, trapezoidal, in V-arrangement or the U-shaped any one, certainly internal tooth 4 also can be rectangular, trapezoidal and inverted V-shaped in any one.
Conduit 1 also can be accomplished through planing or milling operation.
Internal tooth 4 high speed spinning drawing techniques capable of using form, and this technical application is comparatively ripe, and reliable and stable can be produced in batches.
The quantity of outer fin 2 and internal tooth 4 is unrestricted, can be according to the diameter decision of body 1.
As stated, just can realize the present invention preferably.
The foregoing description is merely preferred implementation of the present invention; But embodiment of the present invention is not restricted to the described embodiments; Other are any not to deviate from change, the modification done under spirit of the present invention and the principle, substitute, combination, simplify; All should be the substitute mode of equivalence, be included within protection scope of the present invention.
