Description
Technical field
The utility model relates to lighting field, particularly a kind of module group radiator and lighting device.
Background technology
At present, be that LED light source is connected radiator by the LED matrix (as Tunnel Lamp) of top space illumination downwards, radiator is positioned at directly over LED light source or is positioned at LED light source outside.Consider that single chip LED luminosity is not enough, LED light source generally adopts array architecture, thereby produces the problem that LED light source heat is concentrated, if heat dissipation problem solves bad, will accelerate that it is aging, affect service life.Therefore the design quality of radiator plays a part very important to the life-span of LED.
Solid metallic monolith made by most radiator, in order to increase the contact area with air, increases radiating fin simultaneously, but this solid weight metal is comparatively large, and it is very inconvenient to use.
Application number be 201320720303.1 patent " a kind of LED radiator " disclose the structure of radiator, heat-dissipating casing has made hollow shape, and hollow parts forms heat radiation chamber.But the radiating ribs bottom lock of this heat-dissipating casing, the air of lateral flow can only be relied on to carry out the transmission of heat, and its radiating effect also has much room for improvement.
Utility model content
In order to overcome above-mentioned technical problem, the purpose of this utility model is to provide a kind of light module group radiator, and this lighting device good heat dissipation effect.
The technical scheme that the utility model adopts is:
A kind of module group radiator, comprise metal base plate, the both sides of described metal base plate are respectively equipped with the heat radiation flank upwards extended, inner side and the metal base plate upper surface of described heat radiation flank surround a heat dissipation cavity, described each heat radiation flank comprises the some inside and outside staggered cooling fin arranged along its length, wherein arbitrary cooling fin in inner side and adjacent two form air channel between the cooling fin in outside, the described air channel flank inner space that will dispel the heat is communicated with outer space, and the bottom in described air channel extends to metal base plate bottom face.
As the further improvement of technique scheme, described cooling fin is perpendicular to metal base plate, and described air channel is parallel to cooling fin.
As the further improvement of technique scheme, the top of described heat radiation flank is crossbeam, and the top of the cooling fin in outside is connected directly between crossbeam bottom, and chamfered transition is passed through in top and the crossbeam bottom of the cooling fin of inner side.
The utility model also provides a kind of lighting device, ensure that radiating effect, and its technical scheme is:
A kind of lighting device, comprise LED component and module group radiator, described LED component is arranged on the bottom face of module group radiator, and described LED component, between the air channel of both sides heat radiation flank, makes to expose relative to LED component bottom air channel.
The beneficial effects of the utility model are: the utility model forms air channel by between inside and outside staggered cooling fin, and the bottom in air channel extends to metal base plate bottom face, according to the principle of stack effect, cold wind is initiatively by upwards flowing bottom air channel and entering inner space from flank outer space, thus the heat on heat radiation flank is taken away, by the design in this air channel, greatly strengthen the flowing of air, improve radiating efficiency, and effectively alleviate the design weight of radiator.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is the structural representation of module group radiator;
Fig. 2 is the front view of module group radiator;
Fig. 3 is the upward view of module group radiator;
Fig. 4 is the decomposing schematic representation of lighting device;
Fig. 5 is the upward view of lighting device.
Detailed description of the invention
Module group radiator as shown in Figure 1, comprises metal base plate 1, and the both sides of metal base plate 1 are respectively equipped with the heat radiation flank 2 upwards extended.Inner side and metal base plate 1 upper surface of two heat radiation flanks 2 surround a heat dissipation cavity.
Each heat radiation flank 2 is made up of three parts, comprises the cooling fin arranged along its length and the crossbeam 21 being positioned at cooling fin top.Wherein cooling fin can be divided into inside and outside staggered inner side cooling fin 22 and outside cooling fin 23 successively, and each cooling fin is all connected directly between on metal base plate 1.At grade, and each inner side cooling fin 22 is in another plane parallel with outside cooling fin 23 for each outside cooling fin 23.
In the present embodiment, form air channel 3 between arbitrary inner side cooling fin 22 and adjacent two outside cooling fins 23, air channel 3 flank 2 inner space that will dispel the heat is communicated with outer space, and the air of flowing can pass air channel 3 thus be taken away by the heat on cooling fin.Further, the bottom in air channel 3 extends to metal base plate 1 bottom face, therefore cold wind can directly bottom air channel 3 from the bottom to top enter air channel 3, according to the principle of stack effect, strengthen the mobility of air, thus improve radiating effect.
Preferably, each cooling fin is all perpendicular to metal base plate 1, and air channel 3 is parallel to cooling fin, enters inner side after cold wind rises from air channel 3 bottom vertical from the outside of heat radiation flank 2.Air channel 3, also perpendicular to metal base plate 1, can reduce the resistance of cooling fin for air like this, air is flowed more smooth and easy.
Preferably, crossbeam 21 is positioned at the top of heat radiation flank 2, and the top of outside cooling fin 23 is connected directly between crossbeam 21 bottom, and chamfered transition is passed through in the top of inner side cooling fin 22 and crossbeam 21 bottom.That is to say that the top end in air channel 3 is inclined-plane, after the air of flowing rises to the end, again flow out radiator outside through chamfered transition.And if the end in air channel 3 is plane, the air of rising can be reflected back toward in air channel 3, causes the disorder of fluidised form.
Lighting device as shown in Figure 4 and Figure 5, comprises LED component 4 and module group radiator, and LED component 4 is arranged on the bottom face of module group radiator.This LED component 4, between the air channel 3 of both sides heat radiation flank 2, does not cover air channel 3, makes to expose relative to LED component 4 bottom air channel 3, and therefore cold air is able to unimpeded enter air channel 3.
More than that better enforcement of the present utility model is illustrated, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite without prejudice to the utility model spirit, and these equivalent distortion or replacement are all included in the application's claim limited range.
