Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation of display components, in particular to a heat dissipation shell of a display component. Background Art

[0002] Liquid crystal display is a flat ultra-thin display device, which consists of a certain number of color or black and white pixels, placed in front of a light source or a reflective surface. Liquid crystal display has very low power consumption, so it is favored by engineers and is suitable for electronic devices using batteries. Its main principle is to stimulate liquid crystal molecules with electric current to generate points, lines, and surfaces to form a picture with the back light tube.

[0003] The LED light strips inside the existing LCD displays usually work for a long time and are prone to heat up, resulting in a shortened lifespan. Therefore, they need to be cooled. However, the conventional method is to place the cooling fan on the inside and the filter on the outside. The filter will be clogged with dust every once in a while and needs to be disassembled for cleaning, which is very troublesome. In addition, the heat dissipation port is open, so dust will enter the inner cavity when not in use, increasing the number of cleaning times. For this reason, we propose a display component heat dissipation shell. Utility Model Content

[0010] Preferably, the roller brush is attached to the surface of the filter screen, and the roller brush moves from the middle to both sides.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The device places the fan on the outside and the filter on the inside. The cooling fan on the device is a forward and reverse fan. A roller brush is installed on the device, and the roller brush fits the surface of the filter. After long-term use, dust will be adsorbed on the filter. The roller brush relies on a double-headed motor to drive the gear to run on the rack to achieve forward and backward movement. The double-headed motor drives the roller brush to rotate to clean the surface of the filter. The dust inside will be raised during cleaning. The cooling fan is a forward and reverse fan. The cooling fan rotates forward to cool the inside, and reverses to blow away the raised dust, reducing the number of cleaning times. The device has a simple structure and is easy to use.
