Description
Technical field
The utility model relates to technical field of liquid crystal display more particularly to a kind of heat dissipation backlight frames.
Background technique
Large size liquid crystal display brightness requirement is high, and operating temperature is wide, and circuit board density is big, and structural member is compact.Therefore, it is
Guarantee reliable work, effectively radiates extremely important.Large size liquid crystal display mainly uses the bottom LED backlight lamp source mode.
LED light can generate a large amount of heat at work, especially under high illumination.Therefore LED lamp panel is generally fixed to metal backlight frame
On frame, fixes and conduct heat by metal backlight frame.The fixed various control panels of the other end of backlight frame and power module, after
There is rear cover sealing in face.Since display surface heat flow density is larger, installation fan is usually covered after module, is forced
Exhausting is cooling.For this mode, since rear cavity space is larger, for certain air quantity, air flowing is smaller；Heat source master
It concentrates on LED light postlaminar part i.e. rear cavity bottom, cold air seldom to reach, therefore this mode radiating efficiency is lower.
Application No. is 201320793608.5, in the utility model patent of entitled " radiator of large-screen display "
The heat that LED light generates when working needs just be carried away by the wind through partition, and the presence of partition still causes the heat dissipation of LED light
Undesirable influence.

In order to reach above-mentioned technical purpose, the utility model embodiment provides a kind of heat dissipation backlight frame, the heat dissipation backlight
Frame includes：
Framework, upper surface offer a loophole, and inside offers an accommodating chamber,
Luminescent screen is built in accommodating chamber, is connect with framework inner wall, and emission side is towards loophole；
Heat sink comprising the first heat sink and the second heat sink, the backlight side of the first heat radiation rack adhesive luminescent panel, second
Heat sink is connect with framework inside bottom surface, and surrounds to form component chamber with framework, between the second heat sink and the first heat sink
Air duct is formed, the first heat sink is identical with the second cooling plate structure, including heat radiation rack and multiple is set on heat radiation rack
Semiconductor chilling plate.
Compared with prior art, the utility model has the advantages that：The heat dissipation backlight frame of the utility model uses
Heat sink realizes the fixed function of membrane support in the prior art, and the semiconductor chilling plate in heat sink constantly will
