Abstract

The invention discloses a heat radiation device connecting with a periodic power supply for radiating for circuit board heating element. The radiation device possesses at least a coil, for receiving power supply and producing a magnetic field; and at least a swinging sheet, one end of which is fixed, and other end, suspended correspondingly to coil, wags driven by magnetic force of magnetic field to produce a air current.

Description

technical field [0001] The invention relates to a heat dissipation device, in particular to a heat dissipation device applied to portable electronic devices. Background technique [0002] With the current rapid development of electronic technology and consumers' increasing emphasis on the lightness and portability of consumer electronic products, today's electronic products, such as notebook computers, ultramobile personal computers (UMPC), PDA and other portable electronic products Devices have been gradually miniaturized. For users who need to go out frequently, portable electronic products have become easier to carry, greatly improving the convenience of use. [0003] Taking the ultra-portable computer as an example, due to the fast calculation speed of the electronic components inside the computer device, coupled with the small size of the electronic components, the heat generation per unit area increases accordingly. If the heat is not dissipated in time, the excessive ...
