Description
Technical field
The utility model is related to LED radiator technical field more particularly to a kind of dot matrix Pus for adding grapheme material
Public English type LED radiator.
Background technology
As incandescent lamp is gradually backed out the arena of history, people are more and more urgent for the demand of new type light source, and LED light by
In its high life, high response speed, it is environmentally protective the advantages that be increasingly valued by the people.LED is working as temperature-sensitive element
The heat as fruit chip generates cannot effectively shed in the process, the junction temperature for leading to PN junction be increased, and then seriously affect its work
Performance.The heat dissipation of LED light have become influence its performance and restrict its development key factor, be current research hot spot and
One of difficult point.
In recent years to LED heat dissipation generally use parallel fins construction, also someone it is transformed, such as on fin
Newly crack gap or the corresponding grid of setting in face, and the optimization in flow field is realized with this, enhances thermal convection current, improves its heat dissipation performance.
Current techniques have the following problems and defect：1st, existing parallel fins are due to its form limitation, to wandering
Hot stage effectiveness is general；2nd, current radiators are usually designed around appearance, have ignored the optimization of internal conductive structure and micro-
See the analysis of flow mechanism.
Utility model content
For defect in the prior art or deficiency, technical problem to be solved in the utility model is：There is provided one
The dot matrix dandelion type LED radiator of kind addition grapheme material, considers interior microscopic flowing, the heat dissipation based on free convection
Method, can effectively improve the heat dissipation performance of high-powered LED lamp, and weight mitigates significantly.
To achieve these goals, the technical solution that the utility model is taken is to provide a kind of point for adding grapheme material
Configuration dandelion type LED radiator, the radiator include dandelion type cooling fin, which includes cylindrical body and certainly should
Several outwardly extending radiated ribs of cylindrical body；Further include cylinder graphene in the cylindrical body
Radiating core, several described outwardly extending radiated ribs are separated into 2 sub- fins along bending, outermost end clockwise.
As further improvement of the utility model, the angle of the bending is 3 ° -10 °.
As further improvement of the utility model, the inside of the graphene radiating core uses cancelled structure.
As further improvement of the utility model, the upper surface or lower surface of the graphene radiating core are pasted with
LED chip.
As further improvement of the utility model, the graphene radiating core external cylindrical surface radiates with the dandelion type
The inner cylinder face of piece cylindrical body fits closely.
The beneficial effects of the utility model are：The utility model compared with prior art, has the advantage that：1. pass through
Rotation angle and the mode for increasing sub- fin, increase the contact area of LED light cooling fin, are conducive to improving heat radiation efficiency；2.
Using graphene as taking hot core, under the premise of weight is reduced, significant increase radiating efficiency；3. compared to active heat removal shape
The LED light better economy of formula.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the stereogram of the utility model；
Wherein digital representation：1st, sub- fin；2nd, vent rib；3rd, graphene radiating core.
Specific embodiment
Explanation and specific embodiment further illustrate the utility model below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, the utility model provides a kind of dot matrix dandelion type LED for adding grapheme material and dissipates
Hot device, the radiator include dandelion type cooling fin, outwardly extending several including cylindrical body and from the cylindrical body
A radiated rib 2;Graphene radiating core 3, it is cylinder in the cylindrical body of the dandelion type cooling fin, outside
Cylindrical surface and the inner cylinder face of the dandelion type cooling fin cylindrical body are in close contact, and the LED chips are attached at this
The upper surface or lower surface of graphene radiating core 3, for the LED chip to be transferred to the dandelion type cooling fin.Graphite
Using lattice inside alkene radiating core, construction weight is reduced, improves radiating efficiency.Several described outwardly extending heat dissipations
Fin 2, each fin are 3 ° -10 ° along bending angle clockwise, and outermost end is separated into 2 sub- fins 1, increases heat dissipation area, carries
Radiating efficiency is risen.As a result of the radiating core of graphene material, therefore the radiating efficiency of LED radiators of the present invention is significantly
It improves, weight mitigates significantly.
The above content is combine specific preferred embodiment further detailed description of the utility model, it is impossible to
Assert that the specific implementation of the utility model is confined to these explanations.For the ordinary skill of the utility model technical field
For personnel, without departing from the concept of the premise utility, several simple deduction or replace can also be made, should all be regarded
To belong to the scope of protection of the utility model.
