The utility model discloses no matter transversely can both form the circulation of power air current by the heat source with vertical installation, avoid circular heat dissipation post to install and produce the air current flow on vertical, and transversely the time the overstocked phenomenon of heat source, it is bigger on the heat radiating area space of oval radiator, more be favorable to good ventilation cooling.
Description
Technical field
This utility model relates to heat sink technology field, refers in particular to a kind of high efficiency and heat radiation post。
Background technology
The new type light source that LED light source quickly grows as a kind of extensive use, there is the advantages such as energy-conservation, efficient, volume is little, life-span length, fast response time, driving voltage are low, shock resistance is remarkable compared with conventional light source, but the maximum technology barriers that govern LED light source development at present are exactly conduction of heat and hot settlement issues, the i.e. heat dissipation problem of LED of LED encapsulation。Especially for high-power LED lamp, bad meeting of dispelling the heat causes that the luminous flux of LED chip declines, and LED encapsulation structure is damaged, and electrical parameter changes, and light decay increases severely。
Thus radiator all can be set inside high-power LED lamp, traditional radiator is typically with aluminium or copper material manufacture, its structure is: center is a circular thermal column, the circular uniform heat radiating fin of thermal column outer wall, heat radiating fin, around the surface loop distribution of circular thermal column, adopts said structure heat radiation, and air can not circulate preferably inside radiator, causing that heat sheds slowly, radiating efficiency is low；And, circular thermal column can only produce air current flow on vertical, and thermal source overstocks phenomenon when transverse direction。
Utility model content
This utility model provides a kind of high efficiency and heat radiation post for problem of the prior art。
In order to solve above-mentioned technical problem, this utility model adopts the following technical scheme that
A kind of high efficiency and heat radiation post, including oval radiator, is centrosymmetric in the left and right sides of oval radiator and is provided with several piece radiating fin, form the heat-dissipating space being easy to ventilation and heat between adjacent two pieces of radiating fins；Described radiating fin is one-body molded with oval radiator, and forms a heat radiation angle between radiating fin and oval radiator, and this heat radiation angle is between 50 degree to 65 degree。
Wherein, the two ends up and down of described oval radiator are protruded respectively and are provided with fixed part, and described fixed part offers U-shaped fixing groove。
Wherein, the surface of described radiating fin is provided with some zigzag radiating grooves。
As preferably, described heat radiation angle is 60 degree。
The beneficial effects of the utility model:
A kind of high efficiency and heat radiation post provided by the utility model, including oval radiator, is centrosymmetric in the left and right sides of oval radiator and is provided with several piece radiating fin, form the heat-dissipating space being easy to ventilation and heat between adjacent two pieces of radiating fins；Described radiating fin is one-body molded with oval radiator, and forms a heat radiation angle between radiating fin and oval radiator, and this heat radiation angle is between 50 degree to 65 degree。No matter this utility model laterally can be formed dynamic air-flow by thermal source circulate with vertical installation, it is to avoid circular thermal column can be only installed at and produces air current flow on vertically, and thermal source overstocks phenomenon when transverse direction。The area of dissipation of oval radiator is spatially bigger, is more beneficial for good ventilation heat radiation。
Accompanying drawing explanation
Fig. 1 is the perspective view of a kind of high efficiency and heat radiation post of this utility model。
Fig. 2 is the end view of a kind of high efficiency and heat radiation post of this utility model。
Accompanying drawing labelling in Fig. 1 to Fig. 2 includes:
1 oval radiator, 2 radiating fins, 3 fixed parts, 4 zigzag radiating grooves。
Detailed description of the invention
For the ease of the understanding of those skilled in the art, below in conjunction with embodiment and accompanying drawing, this utility model being further described, the content that embodiment is mentioned is not to restriction of the present utility model。Below in conjunction with accompanying drawing, this utility model being described in detail, on the left and right in this utility model, inferior direction limits with accompanying drawing 2 for reference。
A kind of high efficiency and heat radiation post provided by the utility model, including oval radiator 1, is centrosymmetric in the left and right sides of oval radiator 1 and is provided with several piece radiating fin 2, form the heat-dissipating space being easy to ventilation and heat between adjacent two pieces of radiating fins 2；Described radiating fin 2 is one-body molded with oval radiator 1, and forms a heat radiation angle between radiating fin 2 and oval radiator 1, and this heat radiation angle is between 50 degree to 65 degree。As preferably, described heat radiation angle is 60 degree。
When thermal source transfers heat to oval radiator 1, producing spiral air flow between left side angle radiating fin between two 2 upward, spiral air flow flows to being positioned at right side angle radiating fin 2 down；Meanwhile, the radiating fin 2 on right side also forms spiral air flow after absorbing cold air, and this spiral air flow flows from the right to the left side, and many group air-flows form another strand of spiral air flow again to increase effective heat radiation after combining mutually。Secondary through left side radiating fin 2 pushes, and can accelerate the radiating effect that thermal column is overall。
Radiator in this utility model is oval radiator 1, peripheral theoretical according to static air-flow, several piece radiating fin 2 is centrosymmetric and is arranged at oval radiator 1, and the advantage of this structure is in that this thermal column can change other radiators can not arbitrarily angled installation drawback。Because, conventional radiator generally can only in the horizontal direction or vertical direction just there is good radiating effect；Once occur that overall light fixture tilts, hot stack can be produced, causing light fixture heat radiation imbalance, cause lamp bead junction temperature point temperature height different, having had influence on the life-span of lamp bead, thus having had influence on the life-span of whole lamp。This utility model ellipse radiator is spatially bigger relative to the area of dissipation of circular radiator, is more beneficial for good ventilation heat radiation。
In this utility model, the two ends up and down of described oval radiator 1 are protruded respectively and are provided with fixed part 3, and described fixed part 3 offers U-shaped fixing groove。When installing this thermal column, use the U-shaped fixing groove of screw and fixed part 3 to removably connect, simple and fast is installed。
In this utility model, the surface of described radiating fin 2 is provided with some zigzag radiating grooves 4。Described zigzag radiating groove 4 increases the area of dissipation of radiating fin 2, further speeds up the radiating efficiency of thermal column。
The above, it it is only this utility model preferred embodiment, not this utility model is done any pro forma restriction, although this utility model is with preferred embodiment openly as above, but it is not limited to this utility model, any those skilled in the art, without departing within the scope of technical solutions of the utility model, when the technology contents utilizing the disclosure above makes a little change or is modified to the Equivalent embodiments of equivalent variations, in every case it is without departing from technical solutions of the utility model content, any simple modification that above example is made is referred to according to this utility model technology, equivalent variations and modification, belong in the scope of technical solutions of the utility model。
