Heat sink

Abstract

The invention relates to the technical field of heat dissipation, in particular to a heat sink. The heat sink comprises a fixed base assembly, a magnetic driving component, vibrating components and a fixing component, wherein the magnetic driving component in the fixed base assembly generates a magnetic area under the action of a periodic power supply; actuating magnetic pieces in the vibrating component vibrate under the impact of a varying magnetic field in the magnetic area to further drive elastic sheets to vibrate, and further, heat in electronic or electric equipment is dispelled; and the magnetic driving component is placed in the fixed base assembly. The structure is more compact, the fixing component can be arranged on the outer surface of the fixed base assembly, the mounting end parts of the elastic sheets are fixed, and the fixing component can be arranged on the outer surface of the fixed base assembly in a diversified manner; particularly, the plurality of vibrating components are arranged on the outer side of the fixed base assembly at intervals, and all the elastic sheets are arranged in a mutually non-interference manner during swinging, so that mutual collision of the vibrating elastic pieces is avoided, and the use security of the heat sink is guaranteed.

Description

technical field [0001] The invention relates to the technical field of heat dissipation, in particular to a heat dissipation device. Background technique [0002] At present, heat dissipation devices are often used in many electric equipment and electronic equipment. The common heat dissipation devices are mainly rotary fans, which need to be driven by motor rotation. However, the existing fans and motors have complex structures and large sizes. Fixed installation in equipment and electronic equipment is inconvenient. [0003] There is also a cooling device in the prior art, which generates wind force through the vibration of one or less blades to dissipate heat from electronic or electrical equipment. Although this cooling device is small in size, its structure is not compact enough, and the fixing parts are complicated. When the blades vibrate at the same time, they are prone to collision, resulting in failure. [0004] Therefore, in view of the above deficiencies, it is...
