Beneficial effect：
The air-flow of the present embodiment introduces pipe 5 and the air-flow in air flow system 6 is passed through one on 21 the first side wall 211 of outline border
Opening 2111 introduces in the light source baffle 2 in backlight 3, and by being opened in 20 inner horizontal plate 22 of grill unit and/or riser 23
On multiple ventholes 4, cause air flow through the mobility of its own 2 interior orientation of light source baffle circulate it is more smooth, air-flow is expanding
It is dissipated in light source baffle 2 during each region, not only can directly radiate to light source 1, it can also be to backlight module
On radiate because of the backlight 3 that light source 1 generates heat, last air-flow is from one in the second sidewall 212 of outline border 21 opening
2111 draw.The present invention introduces air-flow from air flow system 6, accelerates to radiate using air-flow, reaches better heat dissipation performance, Duo Getong
The design of stomata 4 allows air-flow to be easier to circulate, and heat dissipation performance is more preferable, improves the service life of light source 1, to improve tool
The service life for having the display device of the radiator, has saved cost.It should be noted that the present invention do not limit light source every
The particular number of transverse slat 22 and riser 23 actual conditions can be configured according to demand with position arrangement relationship, user in shelves 2, this
Invention is not especially limited.
Although some specific embodiments of the present invention are described in detail by example, the skill of this field
Art personnel it should be understood that example above merely to illustrating, the range being not intended to be limiting of the invention.The skill of this field
Art personnel are it should be understood that can without departing from the scope and spirit of the present invention modify to above example.This hair
Bright range is defined by the following claims.
