Abstract

An embodiment of the invention provides a heat dissipation device and communication equipment, which relate to the technical field of heat dissipation, and produce low noise while ensuring heat dissipation of an electronic device. The heat dissipation device comprises a base, a swing sheet and a magnet assembly, wherein the swing sheet comprises a fixed end and a free end, the fixed end is fixed on the base, the free end can swing relative to the fixed end, and an annular coil is arranged on the swing sheet; and the magnet assembly comprises a first magnet and a second magnet which are fixed with respect to the base, the same type of magnetic poles of the first magnet and the second magnet are opposite to each other and are located on two sides of the annular coil, and the annular coil is subjected to an Ampere force periodically changing in direction under the action of a magnetic field formed by the magnet assembly when a current periodically changing in direction is introduced into the annular coil, so that the annular coil drives the swing sheet to swing back and forth. The heat dissipation device is used for heat dissipation of a microelectronic device.

Description

technical field [0001] The invention relates to the technical field of heat dissipation, in particular to a heat dissipation device and communication equipment. Background technique [0002] Nowadays, with the rapid development of electronic technology, electronic devices are more and more widely used in industry. Generally, electronic devices will generate heat during normal operation. If the electronic devices are not dissipated in time, it is likely to damage the electronic devices. device, preventing it from functioning properly. [0003] In order to ensure the normal operation of electronic devices, the prior art generally adopts an electromagnetic rotary fan to dissipate heat. figure 1 An electromagnetic rotary fan provided in the prior art uses electromagnetic rotation to drive blades 30 to rotate to generate air flow for heat dissipation, wherein the outer frame 10 is used to fix the fan at a desired position. This electromagnetic rotary fan solves the heat dissipa...
