Abstract
The present invention relates to an aluminum extrusion heat sink structure and a corresponding backlight module. The aluminum extrusion heat sink structure comprises a light source connecting portion, a back plate connecting portion and a light guide plate support portion. The manufacture cost of the aluminum extrusion heat sink structure is lower, and the heat dissipation effect is better, so as to solve the technology problem that the volume of a traditional aluminum extrusion heat sink structure is larger caused the cost of the aluminum extrusion heat sink structure and the corresponding backlight module is higher.
