Description

Heat radiation structure for display screen and display device Technical Field The utility model relates to the technical field of display equipment, in particular to a heat dissipation structure for a display screen and the display equipment. Background In recent years, with the development of urban construction, the requirements of lamp post screens are increasing, in order to meet the functional requirements of urban beautification, information display and the like, the lamp post screens are developing towards the directions of light weight, large size and small spacing, and the trend leads to more compact internal structure of the lamp post screens and higher power. However, the lamp post screen works outdoors throughout the year, is obviously influenced by external environment, and in addition, in order to meet the waterproof requirement, the space in the lamp post screen is narrow, the tightness is strong, and the brightness and the power of the lamp post screen are high, so that the heat productivity is quite high, and the failure rate of components is increased. At present, the general heat dissipation scheme of lamp pole screen is that internal high temperature air is taken out to outside from the screen through the fan, because the restriction of lamp pole screen space and wiring, main heating parts such as power strip and mainboard are located the screen body in the middle of generally, and the louvre is then offered in lamp pole screen bottom and side, and the fan is installed near the venthole of side frame, because components and parts that generate heat such as power mainboard are farther from the fan, most of heat dissipation air is just directly taken out to the lamp pole screen outside by the fan through these components and parts that generate heat, leads to the local temperature of in the screen too high, the radiating effect is not good.
