Abstract

The invention relates to the technical field of LED display screens, and discloses an LED display screen with heat dissipation effect. The LED display screen with the heat dissipation effect comprisesa housing. One side of the housing is provided with a fan. One side of the fan is fixedly connected with a cold air duct. The inner wall of the cold air duct is fixedly connected with rock wool. Oneend of the cold air duct is fixedly connected with a semiconductor cooler. One side of the semiconductor cooler is fixedly connected with a radiating fin. The inner wall of the housing is fixedly connected with a homogeaezing plate. One side of the homogeaezing plate is fixedly connected with a circuit board. One side of the circuit board is provided with a first insulating layer. The LED displayscreen with the heat dissipation effect is capable of transporting the cold air generated by the semiconductor cooler to the interior of the housing through the fan, enabling the cold air to be uniformly distributed through the homogeaezing plate, and improving the heat dissipation effect. The cold air is transported to each transverse radiating hole for cooling through the homogeaezing plate, theairflow buffering is performed by a spherical heat dissipation buffering hole, the contact area of the cooled airflow with a circuit board, a heating panel and a printed circuit board is increased, and the heat dissipation effect is improved.

Description

technical field [0001] The invention relates to the technical field of LED display screens, in particular to an LED display screen with heat dissipation effect. Background technique [0002] Visible light can be radiated when electrons and holes recombine, so they can be used to make light-emitting diodes. It is used as an indicator light in circuits and instruments, or as a text or number display. Gallium arsenide diodes emit red light, gallium phosphide diodes emit green light, silicon carbide diodes emit yellow light, and gallium nitride diodes emit blue light. Due to chemical properties, it is divided into organic light-emitting diode OLED and inorganic light-emitting diode LED. [0003] As a means of information dissemination, LED display has become a symbol of urban information modernization. With the continuous progress of social economy and the continuous improvement of LED display technology, people have higher and higher requirements for LED display technology. ...
