Abstract

The invention discloses an ion wind forced convection fin applied to heat dissipation of an electronic device. The ion wind forced convection fin comprises a heat dissipation fin body, a notch formed in the heat dissipation fin and used for installing an ion wind generation device, and a banana socket fixed on a fin base plate, wherein the ion wind generation device comprises an upper support, a lower support on which a banana plug is installed, a hollow needle plate electrode arranged in the upper and lower supports and a mesh plate electrode opposite to a needle on the needle plate electrode. According to the fin provided by the invention, air is efficiently ionized via the icon wind generation device, so that ions and free electron are adsorbed on surfaces of dust particles during a motion process, and thus the particles are electrified and adsorbed on the mesh electrode, and meanwhile the generation ion wind is used for improving air velocity from bottom up and reinforce heat convection. The higher wind speed can be generated in a small space, and the reasonable structure design is combined with own characteristics of the heat dissipation fin, so that heat dissipation of the original fin is effectively reinforced, and the problems about reliability of the icon wind generation device and ozone are effectively solved.

Description

technical field [0001] The invention relates to a cooling fin used for various electronic devices with high heat flux density, in particular to an ion wind forced convection fin. Background technique [0002] Traditional fins are commonly used in engineering practice to dissipate large-scale high-power electronic devices such as base stations and servers, and are widely used because of their low price and easy installation. As the power of electronic devices gradually increases, traditional fins are limited by volume, and natural convection is difficult to meet their heat transfer requirements in a limited space. Therefore, forced convection heat transfer is required to enhance heat dissipation, such as using a mechanical fan. Due to the existence of rotating parts in mechanical fans, mechanical wear and vibration will occur during operation, and additional volume will be added, making it difficult to miniaturize. Compared with mechanical fans, ionic wind has the advantages...
