Problems solved by technology

Therefore, the protection level behind the box is low, and dust and humid air can enter the box smoothly, seriously affecting the normal operation of the drive circuit and devices on the back of the module, the switching power supply of the display screen, and the control system.
The second disadvantage is that the heat dissipation problem of the LED display
If an axial flow fan is used, the heat dissipation efficiency is higher, but the noise is louder; if an air conditioner is used for cooling, the heat dissipation efficiency is higher, but the cost of operation is higher, and both methods need to seal the rear of the LED display processing, greatly increasing the difficulty of on-site construction and subsequent maintenance

Abstract

The invention provides an LED display module and an LED splicing display system. The LED display module comprises a box body, an LED display panel assembly, a power supply assembly and a cooling pipe,wherein a first through hole and a second through hole are formed in the box body; the LED display panel assembly is arranged on the front surface of the box body; the power supply assembly is arranged in the box body and is electrically connected with the LED display panel assembly, and is used for controlling the LED display panel assembly to display; the cooling pipe is arranged in the box body, the liquid inlet end and the liquid outlet end of the cooling pipe are connected and communicated with the first through hole and the second through hole respectively, and the power supply assemblyis in contact with the cooling pipe to dissipate heat. According to the LED display module and the LED splicing display system provided by the invention, heat dissipation is carried out on the powersupply assembly through the cooling pipe arranged in the box body, so that the heat dissipation efficiency and effect can be improved.

Description

technical field [0001] The invention relates to the technical field of LED display screens, in particular to an LED display module and an LED splicing display system. Background technique [0002] With many advantages such as high brightness, controllability, long life, energy saving, and safety, LED display screens are constantly being used in various fields. Outdoor advertising signboards are one of the earliest applications of LED displays, but there are always two shortcomings in actual use. The first disadvantage is that the door at the back of the box is of non-sealed structure, and the protection level is low. The heat generated by the drive circuit and devices on the back of the module and the heat generated by the switching power supply of the display screen are all trapped inside the box and cannot be effectively discharged. Therefore, it is necessary to add air inlet and outlet devices at the rear of the box to effectively discharge the heat inside the box. The...
