Description
Technical field
A kind of LED heat abstractors are the utility model is related to, it is more particularly, to a kind of air-cooled heat abstractor, i.e., a kind of air-cooled
Formula LED heat abstractors.
Background technology
Light emitting diode（Abbreviation LED）With small volume, light weight, environment friendly and pollution-free, power consumption is few, the response time is short,
The features such as service life is long.Compared with conventional light source, with the having attracted every country in the world actively research and development of its performance protruded, quilt
The referred to as third time revolution of lighting field.But with the continuous improvement of power, its heat dissipation problem is also more and more prominent, radiating
The further development that problem constrains.
The air-cooled most important part of heat abstractor is fin, by heat transfer caused by pyrotoxin to surrounding air
In play a bridge beam action, fin absorbs heat first, then transfers heat away from, leads to surrounding air heat exchange again
It is most important approach to cross fin radiating.Different radiating sheet forms has a great impact to radiating, including to air flow
Influence, the influence of thermal resistance etc..Most study is rectangular radiator and the nail major class of column radiator two at present.Rectangular
The characteristics of fin is a kind of very common fin, is common in the radiating of various electronic devices, and its is maximum is exactly can be narrow
Larger surface area and very simple processing conditions are obtained in narrow space.But smooth rectangular fins have " comb stream "
Effect, cause fluid to flow out air layer between fin quickly, be unfavorable for exchanging heat.Post shape fin is compared with rectangular fin
With bigger surface area and bigger connection ratio, there is better performance, post enhances the disturbance of fluid, imitates radiating
Fruit strengthens.But flow disturbance is more violent, fluid resistance loss is also bigger, and rate of flow of fluid reduces a lot, is also unfavorable for exchanging heat.
Chinese patent 201610011830.3 discloses a kind of LED anti-explosion lamp, including is cooled down positioned at micro slot group composite phase change
The power source cavity and light-source chamber of radiator both sides, in light-source chamber, between micro slot group composite phase change cooling spreader surface and light source
LED light source installation extension disk is installed, the radiator side surrounds by multiple radiated ribs being vertically arranged, radiated rib it
Between have gap.Program radiating efficiency is not high, and flow resistance is higher, it is impossible to solves the above problems very well.
Utility model content
The utility model overcomes drawbacks described above, there is provided and one kind can strengthen air agitation has large surface area again,
But air flow resistance loss is not again very big air-cooled LED heat abstractors.
The technical scheme in the invention for solving the above technical problem is：A kind of air-cooled LED heat abstractors, including base
Plate and polylith rectangular fins, all rectangular fins are arranged on substrate, it is characterised in that：Also include multiple post shape fin groups,
Post shape fin group is made up of multiple post shape fins, and all post shape fins in same post shape fin group are mutual
Parallel, all rectangular fins and post shape fin group are vertically fixed on the surface of substrate.Rectangular fins and post shape fin with
The main-vision surface angle in 90 ° of substrate, it is rectilinear to be fixed on substrate.
It is parallel to each other between all rectangular fins of the utility model and post shape fin group, rectangular fins and post shape fin
Organize cross arrangement to arrange, an only post shape fin group between the two panels rectangular fins of arbitrary neighborhood, two of arbitrary neighborhood
Only has one piece of rectangular fins between post shape fin group, and the interval between adjacent rectangular fins and post shape fin group is permanent
It is fixed.
All post shape fins are in approximately the same plane in the same post shape fin group of the utility model.
Constant gap between adjacent two panels post shape fin in the same post shape fin group of the utility model.
The beneficial effects of the utility model are：Although there is certain reduction on area of dissipation, not because radiating
The reduction of area and weaken radiating effect, opposite, due to being that the mixing of rectangular fins and post shape fin helps piece, air exists
Flow through and a certain degree of disturbance is received when helping piece, it is this to disturb the effect for enhancing heat exchange.It can also make LED chip simultaneously
Temperature Distribution is unlikely to make chip internal produce excessive thermal stress and influence the service life of chip than more uniform.

Fig. 1 is the main structure diagram in the utility model embodiment.
Fig. 2 is the present invention looks up structural representation in the utility model embodiment.
Fig. 3 is rectangular fins and post shape fin position relationship schematic diagram in the utility model embodiment.
In figure：1- substrates, 2- rectangular fins, 3- post shape fins, 4- post shape fin groups.
Embodiment
Below in conjunction with the accompanying drawings and the utility model is described in further detail by embodiment, and following examples are pair
It is of the present utility model explanation and the utility model is not limited to following examples.
Embodiment.
Referring to Fig. 1-3, the present embodiment is a kind of air-cooled LED heat abstractors, including substrate 1 and polylith rectangular fins 2, institute
There are rectangular fins 2 to install on substrate 1, it is characterised in that：Also include multiple post shape fin groups 4, post shape fin group 4 is by more
Individual post shape fin 3 is formed, and all post shape fins 3 in same post shape fin group 4 are parallel between each other, all rectangles
Fin 2 and post shape fin group 4 are vertically fixed on the surface of substrate 1.Rectangular fins 2 and post shape 3 master with substrate 1 of fin
Depending on face angle in 90 °, rectilinear fixation is on substrate 1.
Preferably, be parallel to each other in the present embodiment between all rectangular fins 2 and post shape fin group 4, rectangular fins 2
