Abstract

The utility model belongs to the LED radiating device, in particular to a dust-proof LED street lamp radiating body, comprising a radiating body; the upper surface of the radiating body is provided with a plurality of radiating fins which are shutter-shaped and inclined; gaps are left among the radiating fins; the adjacent radiating fins are shielded in sequence; the dust only can fall on the tail ends of the radiating fins and can not fall into the root part of the radiating body directly, thus avoiding dust accumulated in long time from having influence on the heat exchange between the radiating body and the air, guaranteeing the radiating effect of the radiating body and being beneficial to improving the working stability of an LED street lamp and prolonging the service life of the LED street lamp.

Description

But dustproof LED road lamp cooling body

Technical field

The utility model belongs to the LED radiating element, but specifically is a kind of dustproof LED road lamp cooling body.

Background technology

For ensureing result of use and working life, the LED street lamp in use, can dispel the heat by radiator mostly, but because the working environment of LED street lamp is outdoor, facing the wind blows the abominable condition of work that drenches with rain with dust pollution so meet unavoidably, too much dust will seriously influence the radiating effect of radiator in case deposited in the radiator surface, directly have influence on the job stability and the service life of LED street lamp.

The utility model content

The utility model is for remedying the deficiencies in the prior art, but a kind of dustproof LED road lamp cooling body is provided, and adopts the shutter principle, and most dust are blocked in outside the radiator, reduces the dust pollution area, ensured the radiating effect of radiator.

For achieving the above object, the utility model has adopted following technical scheme;

But dustproof LED road lamp cooling body, comprise radiator, the upper surface of radiator is provided with into a plurality of radiating fins that blind shaped tilts, leave the gap between the radiating fin, adjacent radiating fin covers successively, dust can only drop to the tail end of radiating fin, can directly not fall into the root of radiator, influences the exchange heat between radiator and air with regard to the dust of having avoided long-term accumulation like this and causes the decline of heat-sinking capability.

In technique scheme, radiating fin all tilts to same direction; Also can divide along the center line of radiator, the radiating fin of both sides tilts respectively toward both sides.

Compare with prior art, the utlity model has following good effect:

The dust of the overwhelming majority is blocked in the tail end of radiating fin, can directly not fall into the root of radiator, avoid the dust of long-term accumulation to influence exchange heat between radiator and air, ensured the radiating effect of radiator, be beneficial to the job stability and the service life of improving the LED street lamp.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is an A of the present utility model portion partial enlarged drawing.

Fig. 3 is the vertical view of Fig. 1.

The specific embodiment

Below in conjunction with specification drawings and specific embodiments the utility model is described further, but protection domain of the present utility model is not limited thereto.

As Fig. 1, Fig. 2 and shown in Figure 3, but dustproof LED road lamp cooling body, comprise radiator 1, the upper surface of radiator 1 is provided with into a plurality of radiating fins 11 that blind shaped tilts, leave the gap between the radiating fin 11, adjacent radiating fin 11 covers successively, and dust 2 can only drop to the tail end of radiating fin 11, can directly not fall into the root of radiator 11, influence the exchange heat between radiator 1 and air with regard to the dust of having avoided long-term accumulation like this and cause the decline of heat-sinking capability.

Described radiating fin 11 all tilts to same direction, also can tilt respectively toward both sides along the center line of radiator 1.

Claims

1. but dustproof LED road lamp cooling body is characterized in that: comprise radiator, the upper surface of radiator is provided with into a plurality of radiating fins that blind shaped tilts, and stays the gap between the radiating fin, and adjacent radiating fin covers successively.

2. but dustproof LED road lamp cooling body according to claim 1 is characterized in that: radiating fin all tilts to same direction.

3. but dustproof LED road lamp cooling body according to claim 1 is characterized in that: the center line along radiator is divided, and the radiating fin of both sides tilts respectively toward both sides.
