Description

A kind of spherical LED lamp radiator of spiral stream guidance

Technical field

The utility model is related to LED lamp heat sink technical fields more particularly to a kind of spherical LED lamp of spiral stream guidance to radiate Device.

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 spherical LED lamp radiator of kind spiral stream guidance, considers interior microscopic flowing, and the heat dissipating method based on free convection 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 to provide a kind of spherical LED of spiral stream guidance Lamp radiator, the barrel-shaped radiator which divulges information for hollow one end, is vertically equipped in the outside wall surface of the radiator Several heat dissipation forks, heat dissipation fork is overhanging, and is decomposed into two pillars, vent rib is set on each pillar, in radiator Several heat dissipation pillars, the pillar of internal face and the heat dissipation pillar of outside wall surface are vertically equipped on wall surface along cylinder helically type, it is described Radiator bottom is provided with the heat emission hole that cold air is facilitated to enter.

As further improvement of the utility model, the rotation angle of the pillar of the internal face and the heat dissipation pillar of outside wall surface It is 5 ° -10 °.

As further improvement of the utility model, the heat emission hole is 2-4.

It is V-arrangement between the heat dissipation fork as further improvement of the utility model.

As further improvement of the utility model, the vent rib on the pillar of the internal face is two, in F types.

As further improvement of the utility model, the lumen of radiator bottom is equipped with LED chip.

The beneficial effects of the utility model are：1. heat dissipation fork and vent rib can increase heat dissipation area, multidimensional is realized Heat dissipation improves radiating efficiency；2. along cylinder, all helically type changes the pillar of wall surface inside and outside, and optimization flowing heat dissipation improves heat dissipation Efficiency；3. can be directly used for spherical LED lamp, integrate practicability and thermal diffusivity；4. compared to the LED light of active heat removal form Better economy.

Specific embodiment

Explanation and specific embodiment further illustrate the utility model below in conjunction with the accompanying drawings.

As shown in Figures 1 to 3, the utility model provides a kind of spherical LED lamp radiator of spiral stream guidance, and LED radiator is The barrel-shaped radiator of hollow one end ventilation is vertically equipped with several heat dissipation forks 4 in the outside wall surface of radiator, which pitches outside 4 It stretches, and is decomposed into two pillars 1, vent rib 2 is set on each pillar 1；It is vertically equipped on the internal face of radiator several Radiate pillar；Heat dissipation fork and vent rib can increase heat dissipation area, realize multidimensional heat dissipation, improve radiating efficiency.Inside and outside wall Along cylinder height, all helically type changes the pillar in face, and rotation angle preferred value is 5 ° -10 °.The presence of the rotation angle, meets inside stream The rule of body flowing, can accelerate flowing.

Meanwhile radiator bottom sets 2-4 heat emission hole 3, to facilitate the entrance of cold air, it is ensured that 360 ° omni-directional dissipates Heat.LED chip is installed on lumen of radiator bottom, and heat transfer finally realizes heat dissipation to barrel-shaped 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.
