Background Along with the continuous promotion of industrial automation level, the industrial control integrated machine is widely applied to various industrial control scenes as key equipment. These application scenarios often require that the industrial control integrated machine have efficient, stable and reliable performance, especially long-term operation capability under severe environmental conditions. However, since a large number of electronic components are integrated therein and a large amount of heat is generated in a high-load operation state, this presents a serious challenge for the heat dissipation capability of the industrial personal computer. The TQY500 type air permeability tester widely used in the industry at present is provided with an AFL-F08A type light industrial tablet personal computer, and the AFL-F08A is provided withThe fan-free system of the Atom TM processor has limited self heat dissipation capacity, and in the daily working process, the peak value of the system running temperature reaches 48 ℃, the partial area of the color liquid crystal touch screen close to the main board generates heat obviously, and the situation that the instrument is blocked and does not respond sometimes occurs, so that the timeliness of the detection work is influenced. Traditional heat dissipation solutions mainly comprise natural cooling, forced air cooling, liquid cooling and other modes.

Liquid cooling technology is favored for its efficient heat dissipation, but its complex system design and high maintenance costs limit its widespread use. Forced air cooling increases the air flow rate through an internal or external fan to improve the heat dissipation effect, and although the heat dissipation efficiency is improved, the fan is easy to block or even damage in the environment with more dust, and the long-term stability of the heat dissipation system is affected.
