Abstract
The utility model discloses an integrated type sunflower-shaped aluminum-made heat pipe structure. The heat pipe structure comprises a sunflower fin, a bottom cover and an upper end cover assembly, wherein the sunflower fin is integrally molded through a metal extrusion process to form a fin structure and an inner groove structure; the groove has various forms including a rectangular shape or an omega shape and the like; the bottom cover, the upper end cover assembly and the sunflower fin are sealed by a soldering process to form a cavity; and a work medium is filled into the cavity and the cavity is vacuumized to form an integrated type sunflower heat pipe structure. The integrated type sunflower-shaped aluminum-made heat pipe structure disclosed by the utility model has the advantages of light structure, high heat radiation efficiency, capability of being arranged at any angle, low cost and the like.
Description
Technical field
The utility model relates to the LED radiator structure, is specifically related to a kind of monoblock type heronsbill type aluminum heat pipe structure.
Background technology
In today of global energy crisis, LED with the high and low power consumption of its luminous efficiency, need not advantages such as high pressure, security height boundless application prospect arranged, like headlight, street lamp, searchlight etc.At present, the LED lamp has only the electric energy about 20% to convert luminous energy in the course of the work, and remaining electric energy almost converts heat energy to, makes that the temperature of LED is very high, has a strong impact on the service life of LED etc., and especially heat dissipation problem is particularly severe concerning great power LED.
Present its complex manufacturing technology of LED radiator, cost is higher, and radiating effect is undesirable.
Summary of the invention
The purpose of the utility model is to overcome the shortcoming and defect of above-mentioned prior art, and the monoblock type heronsbill type aluminum that a kind of technology is simple, radiating efficiency is high heat pipe structure is provided, and effectively solves the heat dissipation problem of great power LED.
The utility model is realized through following technical proposals:
A kind of monoblock type heronsbill type aluminum heat pipe structure; Comprise tubular housing; The periphery equidistance of tubular housing is provided with radiating fin, and the two ends of said tubular housing are provided with the end cap seal assembly that is mated, along spaced apart several " Ω " type grooves that is provided with of the inwall of tubular housing.
Said end cap seal assembly comprises upper end cover, bottom end cover.
Said upper end cover is provided with vacuumizing joint, is provided with seal washer between this vacuumizing joint and the upper end cover.
Offer installing hole on the said radiating fin.
A kind of manufacturing approach of monoblock type heronsbill type aluminum heat pipe structure, following steps:
Adopt the metal material extrusion process; One-shot forming goes out to have radiating fin, tubular housing and " Ω " type groove; Adopt soldering processes that bottom and upper end cover seal weld are connected on the two ends of tubular housing,, extract the vacuum in the tubular housing through vacuumizing joint in tubular cavity perfusion in vivo working medium; Through the port sealing of spot welding, form monoblock type heronsbill heat pipe structure then with vacuumizing joint.
Said employing soldering processes are connected on the two ends of tubular housing with bottom and upper end cover seal weld, and concrete grammar is that soldering lug is put in the junction between tubular housing and bottom, upper end cover, coats scaling powder, puts into vacuum brazing furnace and carries out soldering.
Said vacuumizing joint adopts the one-shot forming of water Sheet Metal Forming Technology.
Compared with prior art the beneficial effect of the utility model is:
Adopt the one-shot forming of metal extrusion process, had radiation fin structure, need not to add the light compactness of structure; Inner " Ω " type groove, its capillary force is big, permeability is strong, can realize long distance, the low temperature difference, the heat exchange of loading greatly; But the centre of radiator structure and edge be processing mounting holes all, satisfies different installation environment demands; The integrated thermal structure does not receive the restriction of setting angle.
The utility model technological means is simple and easy to do, has positive technique effect and application value.
