Abstract
The utility model discloses a high-efficiency radiator. The high-efficiency radiator comprises radiating columns. A plurality of radiating fins are disposed on the outer walls of the radiating columns and distributed axially along the radiating columns. A central radiating hole is reserved in the radiating columns and a plurality of auxiliary radiating holes are reserved on the radiating fins. The auxiliary radiating holes are annularly distributed around the central axis of the radiating columns and communicated with the central radiating hole through radiating gaps. A plurality of convection passages distributed in the radiator are formed due to the fact that the central radiating hole and the auxiliary radiating holes are communicated with gaps among the radiating fins. Accordingly, heat absorbed by the radiating columns and the radiating fins can be radiated fast through air convection and the radiator is fine in radiating effect and high in radiating efficiency.
Description
Technical field
The utility model relates to a kind of radiator, particularly a kind of high-efficiency radiator that is mainly used in the LED light fixture.
Background technology
At present; Led light source develops new type light source rapidly as a kind of extensive use; Energy-conservation, efficient, advantages such as volume is little, the life-span is long, response speed is fast, driving voltage is low, shock resistance brilliance have been compared with conventional light source; But the maximum technology barriers that restricting the led light source development at present are exactly heat conduction and the heat sink problem of falling, the i.e. heat dissipation problem of LED of LED encapsulation.Particularly to high-power LED lamp, the bad meeting of dispelling the heat causes the luminous flux of led chip to descend, and the LED encapsulating structure damages, and electrical parameter changes, and light decay increases severely.
Thereby high-power LED lamp inside all can be provided with radiator, and traditional radiator normally adopts aluminium or copper material manufacturing, and its structure is: the center is a cylinder; Cylindrical outer wall is uniformly distributed with heat radiating fin; Heat radiating fin adopts the said structure heat radiation around the periphery annular distribution, and air can not circulate in radiator inside preferably; Cause heat to shed slowly, radiating efficiency is low.
Summary of the invention
In order to overcome the deficiency of prior art, the utility model provides a kind of good heat dissipation, radiator that radiating efficiency is high.
The utility model solves the technical scheme that its technical problem adopted:
A kind of high-efficiency radiator; It is characterized in that: comprise thermal column, the outer wall of this thermal column is provided with some fin, and this fin is along the axial distribution of this thermal column; Said thermal column is provided with the center louvre; Said fin is provided with some auxiliary heat dissipations hole, and this auxiliary heat dissipation hole is annular spread around the axis of this thermal column, and this auxiliary heat dissipation hole and center louvre are through heat radiation slit UNICOM.
As the preferred version of the utility model, said thermal column is provided with the heat radiation installed surface that contacts with radiator.
As the further preferred version of the utility model, fin axially evenly distributes along this thermal column.
Said auxiliary heat dissipation hole is provided with five.
The beneficial effect of the utility model is: the utility model comprises thermal column; The outer wall of this thermal column is provided with some fin; And this fin is along the axial distribution of this thermal column, and said thermal column is provided with the center louvre, and said fin is provided with some auxiliary heat dissipations hole; This auxiliary heat dissipation hole is annular spread around the axis of this thermal column, and this auxiliary heat dissipation hole is communicated with through the heat radiation slit with the center louvre.The utility model forms the convection channel in a plurality of distribution radiators through the mutual UNICOM in the gap between fin and center louvre and auxiliary heat dissipation hole; Thereby; The heat that thermal column and fin absorbed can be got rid of through cross-ventilation fast, and not only good heat dissipation but also radiating efficiency are high.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified:
Fig. 1 is the overview of the utility model;
Fig. 2 is the overview of another direction of the utility model;
Fig. 3 is the front view of the utility model;
Fig. 4 is the vertical view of the utility model.
Embodiment
Referring to figs. 1 through Fig. 4, the utility model discloses a kind of high-efficiency radiator, comprise thermal column 1; The outer wall of this thermal column 1 is provided with some fin 2; And this fin 2 is along the axial distribution of this thermal column 1, and said thermal column 1 is provided with center louvre 3, and said fin 2 is provided with some auxiliary heat dissipations hole 4; This auxiliary heat dissipation hole 4 is annular spread around the axis of this thermal column 1, and heat radiation slit 5 UNICOMs are passed through with center louvre 3 in this auxiliary heat dissipation hole 4.
As shown in the figure, in order to try one's best in time the heat absorption of heater, thermal column 1 is provided with the heat radiation installed surface 6 that contact with radiator, the installed surface 6 that dispels the heat compare fin 2 increased contact with radiator area.
As shown in the figure, for better radiating effect is arranged, fin 2 axially evenly distributes along this thermal column 1.Further; In this specific embodiment, auxiliary heat dissipation hole 4 is surrounded by the breach of fin 2 and thermal column 1, and auxiliary heat dissipation hole 4 is provided with five; Annular evenly distributes around the axis of this thermal column 1 in five auxiliary heat dissipation holes 4; Certainly, above-mentioned just present embodiment preferred, the quantity in auxiliary heat dissipation hole 4 also can be four or six etc.
Above-mentionedly just some preferred embodiments of the utility model are illustrated and describe; But the execution mode of the utility model is not restricted to the described embodiments; As long as it reaches the technique effect of the utility model with essentially identical means, all should belong to the protection range of the utility model.
