A method and device for computer-aided design of large LED screens

Abstract

The invention discloses a method and device for computer-aided design of a large LED screen, belonging to the technical field of LED screens. When a computer-aided design device debugs the large screen, the debugging time is long and the temperature of the device during operation is high. However, the device itself lacks a heat dissipation function, which makes the heat dissipation of the device more troublesome. At the same time, the high temperature affects the operation efficiency of the device. By driving a movable sleeve to move back and forth and driving a rotating shaft to rotate back and forth at the same time, the rotating shaft causes a fan to rotate back and forth through a connecting sleeve and a connecting rod. The fan moves back and forth and rotates back and forth. The airflow generated when the fan is operating passes through an air inlet slot to cool down an auxiliary integrated terminal. The high-temperature hot airflow in a protective box is discharged through a second heat dissipation slot and a first heat dissipation slot, thereby conveniently realizing the cooling and heat dissipation of the auxiliary integrated terminal, thereby effectively improving the heat dissipation effect of the auxiliary integrated terminal, and at the same time, improving the operation efficiency of the auxiliary integrated terminal.

At this time, the fan 35 reciprocates horizontally and reciprocates. The airflow generated by the fan 35 during operation cools the auxiliary all-in-one terminal 2 through multiple air inlet slots 17. At the same time, the high-temperature hot air flow in the protective box 1 is discharged through multiple second heat dissipation slots 83 and multiple first heat dissipation slots 15 until the temperature of the auxiliary all-in-one terminal 2 meets the temperature range required during operation, and then the servo motor 41 and the fan 35 are turned off, thereby conveniently realizing the cooling and heat dissipation of the auxiliary all-in-one terminal 2, thereby effectively improving the heat dissipation effect of the auxiliary all-in-one terminal 2, and at the same time, improving the operating efficiency of the auxiliary all-in-one terminal 2.
