Description

LED lamps cooling device

Technical field

LED lamps cooling technical field is the utility model is related to, more particularly to a kind of LED lamps cooling device.

Background technology

LED industrially has been obtained for being widely applied very much, including automotive lighting, traffic lights etc., but LED's is scattered Heat problem is all an important factor for limitation great power LED develops all the time, because the performance of LED and service life all cease with its junction temperature Manner of breathing closes, so the design of radiator is even more important.LED lamps cooling device mainly divides passive heat radiation and active heat dissipation Two kinds.Wherein, active heat dissipation is to rely on fan cooling, and active heat dissipation effect is significantly stronger than passive heat radiation.

Existing active heat sink structure is relatively simple, although heat dissipation effect is significantly stronger than passive heat radiation, also It is to have the following disadvantages：

1st, fan is close to LED chip arrangement, is not easy to matrix LED heat dissipation；

When the 2nd, there are multiple LED light modules in lamps and lanterns, multiple radiator fans need to be equipped with, increase lamps and lanterns cost, space and again Amount.

Utility model content

The utility model is in view of the problems of the existing technology and insufficient, there is provided a kind of new LED lamps cooling device.

The utility model is to solve above-mentioned technical problem by following technical proposals：

The utility model provides a kind of LED lamps cooling device, its feature is, it includes a fan, one for shunting Guide duct, a stent and multiple radiators, the mounting base of the upper surface of each radiator and corresponding installation speculum is mutually solid Fixed, the upper surface of each radiator forms the cavity of a receiving LED chip with the bottom of corresponding mounting base, on each radiator Drainage radiation air is offered to the air inlet of LED chip position；

Those radiators are fixed on the stent, and an air inlet, the air outlet direction of the fan are offered on the guide duct The air inlet of the guide duct, the guide duct are divided into multiple air-guiding aisles, those air-guiding aisles are corresponded with those radiators, The guide duct intersects with the stent, and the radiator is located at the top of corresponding air-guiding aisle, the air outlet of the air-guiding aisle Towards the air inlet of corresponding radiator, the thang-kng air outlet above and below perforation, the inlet air of the radiator are offered in the mounting base Mouthful towards the thang-kng air outlet in corresponding mounting base.

It is preferred that the angle of the air outlet of the air-guiding aisle and corresponding radiator upper surface is in obtuse angle.

It is preferred that the lower surface of each radiator is equipped with heat radiating fin.

On the basis of common knowledge of the art, above-mentioned each optimum condition, can be combined, up to the utility model respectively compared with Good example.

The positive effect of the utility model is：

The wind that the utility model is imported into guide duct by fan adds the air flow of whole lamp interior, by wind Fan it is multiple and efficiently use, reached drop this loss of weight effect, bicycle reduce about 500 yuan of costs, moreover, effectively reducing The temperature of LED chip, only 125 DEG C of highest analog temperature, less than LED junction temperature, meets design requirement.

Brief description of the drawings

Fig. 1 is the exploded view of the LED lamps cooling device of the utility model preferred embodiment.

Fig. 2 is the assembling figure of the LED lamps cooling device of the utility model preferred embodiment.

Embodiment

It is new below in conjunction with this practicality to make the purpose, technical scheme and advantage of the utility model embodiment clearer Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched The embodiment stated is the utility model part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model Example, those of ordinary skill in the art's all other embodiments obtained on the premise of creative work is not made, all belong to In the scope of the utility model protection.

As depicted in figs. 1 and 2, the present embodiment provides a kind of LED lamps cooling device, including a fan 1, one to be used to shunt Guide duct 2, a stent 3 and multiple radiators 4 (present embodiment illustrates 6 radiators), the upper surface of each radiator 4 with 5 phase of mounting base of corresponding installation speculum is fixed, and the upper surface of each radiator 4 is formed with the bottom of corresponding mounting base 5 One accommodates the cavity of LED chip 6, drainage radiation air is offered on each radiator 4 to the air inlet 41 of LED chip position, often The lower surface of one radiator 4 is equipped with heat radiating fin.

Those radiators 4 are fixed on the stent 3, offer an air inlet on the guide duct 2, the air outlet of the fan 1 Towards the air inlet of the guide duct 2, which is divided into multiple air-guiding aisles 21, those air-guiding aisles 21 and those heat dissipations Device 4 corresponds, which intersects with the stent 3, and the radiator 4 is located at the top of corresponding air-guiding aisle 21, should The air outlet of air-guiding aisle 21 offers the thang-kng above and below perforation in the mounting base 5 and goes out towards the air inlet of corresponding radiator 4 Air port, the air inlet of the radiator 4 is towards the thang-kng air outlet in corresponding mounting base 5.

In the present embodiment, the angle of the air outlet of the air-guiding aisle 21 and corresponding 4 upper surface of radiator in obtuse angle, with 6 surface of LED chip is set to form heat dissipation laminar winds, the light that LED chip 6 is sent is irradiated on mirror surface through thang-kng air outlet, Radiating airflow is also exported from thang-kng air outlet.

The wind that the utility model is imported into guide duct by fan adds the air flow of whole lamp interior, by wind Fan it is multiple and efficiently use, reached drop this loss of weight effect, bicycle reduce about 500 yuan of costs；And effectively reduce LED The temperature of chip, only 125 DEG C of highest analog temperature, less than LED junction temperatures, meets design requirement；So that LED chip is positive, heat dissipation Device, mounting base and the heat of reflective mirror can also be taken out of with radiating airflow thereon.

Although the foregoing describing specific embodiment of the present utility model, it will be appreciated by those of skill in the art that These are merely illustrative of, and the scope of protection of the utility model is defined by the appended claims.Those skilled in the art Member can make these embodiments numerous variations or repair on the premise of the principle and essence without departing substantially from the utility model Change, but these change and modification each fall within the scope of protection of the utility model.
