¿Cómo disipa el calor la computadora de panel industrial integrada sin ventilador? La racionalidad de la estructura de disipación de calor es un factor importante relacionado con el funcionamiento estable de la computadora industrial. La temperatura excesiva provocará la inestabilidad del sistema informático del panel industrial y acelerará el envejecimiento de las piezas. Con la mejora continua de la frecuencia de la CPU, el uso generalizado de unidades de estado sólido y el reemplazo frecuente de tarjetas gráficas de alto-rendimiento, la disipación de calor interna de las tabletas industriales ha recibido cada vez más atención.
At present, most industrial control cabinets adopt dual-program interactive cooling: the external low-temperature air is sucked into the cabinet through the high-speed ball fan at the front of the cabinet and the cooling holes on both sides of the cabinet, and passes through the hard disk rack, north bridge chip, various boards and north bridge chips, and then Arrived near the central processing unit. After passing the central processor radiator, part of the hot air is drawn out of the cabinet from the two high-speed spherical exhaust fans at the back of the cabinet, and the other part is exhausted from the cabinet by the power supply fan. The industrial control cabinet adopts a spherical fan, which has large air volume, high speed, low heat generation, long life and low noise, and realizes efficient heat dissipation. In order to avoid the chaotic wiring in the chassis from affecting the airflow, some manufacturers set wire clamps at appropriate positions to fix the data cables and power cables in a position that does not affect the air duct. Some manufacturers add fans to the sides and top of the industrial control cabinet to "improve" the dual-program interactive cooling channel, thereby changing the airflow in the control cabinet. After the air outside the cabinet enters the cabinet, due to the forced convection of the fan on the top of the cabinet, part of the low-temperature air does not reach the central processing unit according to the original route, and is directly drawn out of the cabinet, reducing the heat dissipation effect of the low-temperature air.
In order to cool high-speed hard drives, some manufacturers install additional intake fans at the front of the drive rack, which can not only increase the air flow in the chassis, but also directly cool the hard drives. Another method is to move the traditional hard disk installation position down so that the hard disk is in contact with the bottom of the chassis. The chassis bottom plate is used to enhance the heat dissipation of the hard disk, and the fresh low-temperature air can first radiate to the hard disk after entering the chassis, which greatly reduces the heat of the hard disk and prolongs the service life of the hard disk. With the widespread application of industrial control, factors such as structure and volume directly affect the development direction of industrial control computers, and embedded industrial panel computers have emerged. Embedded industrial computers have the characteristics of low power consumption, small size, no fan, and strong stability. Its passive heat dissipation method greatly improves the reliability of the product and completely solves the problems of insufficient heat dissipation and insufficient service life of traditional industrial tablet computers.
