Description
Technical field
The utility model relates to LED radiator fields, and in particular to a kind of specific shape fin collocation type LED radiator.
Background technique
The heat dissipation of current various electronic components is always the significant problem developed in limitation field.Heat dissipation problem is not
The good working performance for causing device declines, service life reduction, or even directly damages.Especially for some powerful devices, heat dissipation
Problem is particularly important.
Gilled radiator is a kind of structure radiator the simplest, but shape is easy around the fin structure of rule
At thermal boundary layer, causes heat flow field to be unfavorable for scattering and disappearing for heat, reduce radiator performance.Edge fin temperature when radiator works
Degree is not high, but its height, as the fin of middle part, this hinders the heat loss of middle part fin.Fin in the middle part of radiator is necessary
Certain density is kept just to can guarantee that the heat on foot of radiator is largely transferred on fin, but excessively intensive fin
Cause the difficulty of heat loss.
Utility model content
The purpose of the utility model is to overcome the defects of the prior art, provide a kind of specific shape fin collocation type
LED radiator.The specific shape fin collocation type LED radiator includes: including base plate of radiator, end fin, long short fin
Group, high fins set.
The parallel both ends for being set to base plate of radiator of the end fin.
The short fins set of length is uniformly fixed on the base plate of radiator between two end fins, and the short fins set of length is relatively held
The high 5-10mm of fin.The temperature at base plate of radiator both ends is not high, and end fin is excessively high, will affect the heat dissipation at middle part.Long short fins set
Both ends exceed base plate of radiator, can enhance heat dissipation effect.
The high fins set is uniformly fixed on the base plate of radiator in the gap between long short fins set, the high fin
The single high fin height arranged in group from center to both ends gradually decreases, each single high fin top in the high fins set
For the consistent dome of shape, such design can reduce thermal boundary layer and be formed, and improve radiator performance.The high fins set is most
The single high longer short high 5-10mm of fins set in fin highest point in outside.
Optionally, length of the short fins set both ends of the length beyond base plate of radiator is 5-10mm.
Optionally, the single high fin height arranged in the high fins set from center to both ends gradually decreases 2-5mm.
The utility model specific shape fin collocation type LED radiator adjusts the length and height of different location fin, leads to
The collocation of specific shape fin is crossed, when guaranteeing fin density, enhances Natural Heat Convection effect.Added using fan
When strong heat dissipation, better effect.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawings and detailed description,
Fig. 1 is a kind of overall schematic of specific shape fin collocation type LED radiator of the utility model.
Fig. 2 is the utility model individually high fin schematic diagram.
Appended drawing reference: 1- base plate of radiator, the end 2- fin, the short fins set of 3- long, 4- high fins set, 41- individually high fin,
411- dome.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example.The utility model is described in further detail.
As shown in Figs. 1-2, the utility model discloses a kind of specific shape fin collocation type LED radiator；Including heat dissipation
Device bottom plate 1, end fin 2, long short fins set 3, high fins set 4.
The parallel both ends for being set to base plate of radiator 1 of the end fin 2.
The short fins set 3 of length is uniformly fixed on the base plate of radiator 1 between two end fins 2, the short fins set 3 of length
It is 5-10mm high compared with end fin 2.The temperature at 1 both ends of base plate of radiator is not high, and end fin 2 is excessively high, will affect the heat dissipation at middle part.Length is short
3 both ends of fins set exceed base plate of radiator 1, can enhance heat dissipation effect.
The high fins set 4 is uniformly fixed on the base plate of radiator 1 in the gap between long short fins set 3, the height
Single high 41 height of fin arranged in fins set 4 from center to both ends gradually decreases, each single high in the high fins set 4
It is the consistent dome 411 of shape at the top of fin 41, such design can reduce thermal boundary layer and be formed, and improve radiator performance.
The outermost single high longer short fins set 3 in 41 highest point of fin of high fins set 4 is 5-10mm high.
In specific implementation, length of short 3 both ends of fins set of length beyond base plate of radiator 1 is 5mm.
In specific implementation, single high 41 height of fin arranged in the high fins set 4 from center to both ends is gradually decreased
3mm。
Embodiment is only one embodiment of the utility model, for those of ordinary skill in the art, is not being paid
Under the premise of creative labor, other embodiments can also be obtained with reference to the accompanying drawings, also in the protection scope of the utility model
Within.
