Problems solved by technology
[0002] With the development of electronics and multimedia technology, various digital display devices are used in various indoor and outdoor occasions. Most of the existing digital display devices are single-sided or double-sided display, while multi-sided digital display devices are relatively rare, and Due to the increase of multi-faceted digital display device components, image display modules, and power modules during use, the corresponding additional heat requires more effective temperature control products to solve the temperature control problem, otherwise it will often lead to the internal temperature of the multi-faceted digital display device cabinet. If it is too high, it will cause a black screen
In the past, there were some temperature control schemes where the air conditioner installed at the bottom blows cold air upwards. However, due to design defects, the airflow distribution inside the cabinet is unreasonable, which may easily lead to short circuit of the hot airflow and fail to achieve the desired cooling effect.

Description
technical field [0001] The invention relates to temperature-controllable video playback equipment, in particular to a multi-faceted digital display device with a built-in temperature control device. Background technique [0002] With the development of electronics and multimedia technology, various digital display devices are used in various indoor and outdoor occasions. Most of the existing digital display devices are single-sided or double-sided display, while multi-sided digital display devices are relatively rare, and Due to the increase of multi-faceted digital display device components, image display modules, and power modules during use, the corresponding additional heat requires more effective temperature control products to solve the temperature control problem, otherwise it will often lead to the internal temperature of the multi-faceted digital display device cabinet. If it is too high, a black screen will appear. Previously, there were some temperature control s...
