Title: HEAT DISSIPATION DEVICE, HEAT DISSIPATION UNIT, AND ELECTRONIC APPARATUS
Abstract:
Provided are a heat dissipation device, a heat dissipation unit, and an electronic apparatus. The heat dissipation device comprises a base (110), a blade-shaped oscillating heat dissipation assembly (120), a driving assembly (130), and a magnetic assembly (140). The driving assembly is fixed to the base. One end of the blade-shaped oscillating heat dissipation assembly is fixed to the base and located in the same plane as the base. There is an included angle between the blade-shaped oscillating heat dissipation assembly and a vertical plane of the base. The magnetic assembly is provided at the blade-shaped oscillating heat dissipation assembly. The magnetic assembly is arranged in a position corresponding to the driving assembly. A force acting between the magnetic assembly and the driving assembly drives the blade-shaped oscillating heat dissipation assembly to oscillate. An oscillation area of the blade-shaped oscillating heat dissipation assembly constitutes a large fan-shaped area, such that an air volume generated by the blade-shaped oscillating heat dissipation assembly is significantly increased, thereby expanding a heat dissipation area.
