Abstract

The invention discloses an outdoor heat dissipation and dust removal LED display screen. The display screen comprises a bracket and a fixing plate with a convex structure. A fixing groove is formed inthe fixing plate, and the bottom of the fixing groove is fixedly connected with a display screen. The fixing groove is provided with an evaporation cavity and a work cavity in a communicated mode. Acirculating cavity is formed in the side, away from the fixing groove, of the fixing plate. The evaporation cavity and the work cavity are sealed through a sealing plate. A first impeller is rotationally connected into the work cavity, and a rotating shaft is fixedly connected to the rotation center of the first impeller. The LED display screen has the advantages that heat of the LED display screen is absorbed through the evaporation liquid, evaporated gas is used for driving the impeller to rotate, internal energy is converted into mechanical energy, the surface of the display screen is brushed through conversion of the mechanical energy, and the effect of spontaneous heat dissipation and dust removal is achieved.

Description

technical field [0001] The invention relates to the technical field of LEDs, in particular to an LED display screen for outdoor heat dissipation and dust removal. Background technique [0002] LED display is a kind of flat panel display, which is composed of small LED module panels, and is used to display various information such as text, image and video. LED electronic display integrates microelectronics technology, computer technology and information processing. , has the advantages of bright colors, wide dynamic range, high brightness, long life, stable and reliable work, etc. LED displays are widely used in commercial media, cultural performance markets, stadiums, information dissemination, press releases, securities transactions, etc., and can meet the needs of different environments. [0003] However, in the prior art, the use of outdoor LED display screens often results in poor heat dissipation due to the high outdoor temperature, and in weather conditions, the pollu...
