The side plate extends toward the first direction from the edge of the base plate. The plurality of heat dissipation fins respectively extend toward the second direction from the middle of the base plate. The first direction is opposite to the second direction. The utility model further discloses a liquid crystal display device utilizing the backlight module. Compared with the prior art, the backlight module and the liquid crystal display device have the advantages of being high in heat dissipation efficiency and low in cost.
Description
Technical field
The utility model relates to a kind of radiating effect preferably backlight module and the liquid crystal indicator of using described backlight module.
Background technology
In the prior art, the radiating mode of backlight module has two kinds usually.The first radiating mode is by lower chase heat radiation, and this radiating mode only utilizes the heat conductivility heat radiation of aluminium self, can not effectively reduce the temperature of backlight module.The second radiating mode is that increase fin and heat-conducting glue come auxiliary heat dissipation, although this radiating mode can effectively reduce the temperature of backlight module, its cost is higher, has also increased the weight of backlight module.
The utility model content
The technical problem that the utility model mainly solves is that the radiating efficiency of existing backlight module is limited, cost is higher.
In order to solve the problems of the technologies described above, the utility model embodiment discloses a kind of backlight module, described backlight module comprises metal back frame, described metal back frame comprises base plate, side plate and a plurality of radiating fin, described side plate extends to first direction from the edge of described base plate, described a plurality of radiating fin extends to second direction from the middle part of described base plate respectively, and described first direction is opposite with described second direction.
In a preferred embodiment of the present utility model, described metal back frame comprises two side plates, described two side plates respectively with angled connection of edge of two relatively short sides of described base plate.
In a preferred embodiment of the present utility model, described base plate comprises a plurality of openings, the respectively corresponding described a plurality of opening settings of described a plurality of radiating fins.
In a preferred embodiment of the present utility model, the width of described opening is identical with the width of described radiating fin.
In a preferred embodiment of the present utility model, described a plurality of radiating fins are arranged in parallel.
In a preferred embodiment of the present utility model, the length of described opening be described base plate width 1/3 to 3/4.
In a preferred embodiment of the present utility model, described radiating fin comprises diapire and pair of sidewalls, and described pair of sidewalls is connected with described base plate is angled respectively, and described diapire is connected with described pair of sidewalls respectively, and parallel with described base plate.
In a preferred embodiment of the present utility model, described radiating fin and the described base plate structure that is formed in one.
In order to solve the problems of the technologies described above, the utility model embodiment also discloses a kind of liquid crystal indicator, described liquid crystal indicator comprises backlight module, described backlight module comprises metal back frame, described metal back frame comprises base plate, side plate and a plurality of radiating fin, described side plate extends to first direction from the edge of described base plate, and described a plurality of radiating fins extend to second direction from the middle part of described base plate respectively, and described first direction is opposite with described second direction.
Compared to prior art, described backlight module of the present utility model and liquid crystal indicator form a plurality of described radiating fins by Sheet Metal Forming Technology cheaply on metal back frame, the area of dissipation that it has increased described metal back frame has largely promoted radiating efficiency.In addition, described a plurality of openings of corresponding described a plurality of radiating fins have strengthened circulation of air respectively, therefore further promoted the radiating efficiency of described backlight module, described backlight module and the liquid crystal indicator of using described backlight module have higher, the lower-cost advantage of radiating efficiency.
