Description
Technical field
The utility model is related to LED radiator technical field more particularly to a kind of wings for setting spiral formula diversion trench
Sheet-shaped 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 finned LED radiator of kind setting spiral formula diversion trench, considers interior microscopic flowing, the heat dissipation side based on free convection
Method can effectively improve the heat dissipation performance of high-powered LED lamp.
To achieve these goals, the technical solution that the utility model is taken is provides a kind of setting spiral formula water conservancy diversion
The finned LED radiator of slot, the radiator include cylindrical body and are dissipated from outwardly extending several of the cylindrical body
Hot fin；Radiating core is installed in the cylindrical body, which is cylinder, external cylindrical surface outside and fin contacts
Position setting spiral diversion trench.
As further improvement of the utility model, it is arranged to around the radiating core and LED chip contact position recessed
Groove shape.
As further improvement of the utility model, the upper section of the radiating core is octagon.
It is octagonal among the bottom of the radiating core as further improvement of the utility model, periphery hollow out.
As further improvement of the utility model, the upper surface or lower surface of the radiating core are pasted with LED chips,
For the LED chip to be transferred to the radiator.
The beneficial effects of the utility model are：1st, LED light PN junction is considered emphatically and takes the heat dissipation of hot core junction, is improved
The problem of local temperature is excessively high；2nd, using spiral formula diversion trench, the helical form for being not only advantageous to thermal current rises；And
The contact area of air-flow and fin can be increased, promote heat dissipation comprehensively；3rd, it can be used for mass producing, there is practical significance；
4th, compared to the LED light better economy of active heat removal form.
Description of the drawings
Fig. 1 is the radiating core upper section schematic diagram of the utility model；
Fig. 2 is the lower section side view of the utility model；
Fig. 3 is the lower section schematic diagram of the utility model；
Fig. 4 is the structure diagram of the utility model；
Wherein digital representation：1st, radiating core.
Specific embodiment
Explanation and specific embodiment further illustrate the utility model below in conjunction with the accompanying drawings.
As shown in Figures 1 to 4, the utility model provides a kind of finned LED heat dissipations for setting spiral formula diversion trench
Device, the radiator include cylindrical body and from several outwardly extending radiated ribs of the cylindrical body；The cylindrical shape
Radiating core 1 is installed, which is cylinder, and external cylindrical surface outside and the position of fin contacts are set in spiral in ontology
Diversion trench is risen, the helical form for being not only advantageous to thermal current rises, and can increase contact of the thermal current with radiating fin, promotes
The rapid dispersion of heat.
As shown in Figure 2,3, it is arranged to groove shapes around the radiating core and LED chip contact position.Increase this to connect
Touch position（Temperature highest）Locate the contact with surrounding flow field, reduce the junction temperature of LED light PN junction, also increase to a certain extent scattered
The approach of heat.The heat that most at last LED is generated is transmitted to fin by support column, interior flow field, and heat dissipation is carried out by fin,
Realize the purpose of LED heat dissipations.
As shown in Fig. 1,4, the upper section of the radiating core is octagon.
As shown in Figure 2,3, it is octagonal, periphery hollow out among the bottom of the radiating core.
The upper surface or lower surface of the radiating core are pasted with LED chips, described for the LED chip to be transferred to
Radiator.
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.
