Abstract

The invention discloses a device for improving the intensity of ionic wind through cooperation of a magnetic field and a carbon nano tube. The device comprises an ionic wind generation unit and a metal heat dissipation device; an LED chip to be cooled is fixed on the lower end face of the metal heat dissipation device; the ion wind generation unit is arranged on the upper portion of the metal heat dissipation device through a fixing support, ion wind is generated by the ion wind generation unit, convection heat exchange is conducted on the metal heat dissipation device through the ion wind, and then enhanced heat dissipation of the LED chip is achieved. The permanent magnet is installed in the device to provide a magnetic field environment to increase the speed of ion wind; when the device is applied to heat management of a high-power LED chip, corona current under the same discharge voltage is remarkably reduced, and energy consumption is reduced; and meanwhile, the carbon nano tube coating a needle tip inhibits the generation of ozone in corona discharge. The device is simple in overall structure, low in power consumption, reliable in work and green and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of enhanced heat dissipation of electronic devices, and in particular relates to a device for synergistically enhancing the intensity of ion wind by a magnetic field and carbon nanotubes. Background technique [0002] The development trend of high performance, integration and miniaturization of electronic devices makes the excessive accumulation of internal heat, and the heat flux density is getting higher and higher. If the heat accumulated in a small space cannot be dissipated in time, the working temperature of the electronic device will continue to rise; when the temperature exceeds the limit temperature, its working performance will decrease and its service life will be shortened. bodily injury. Therefore, it is urgent to seek efficient cooling measures. [0003] There are more or less defects in the traditional heat dissipation method, and the ion wind heat dissipation has the advantages of low energ...
