Problems solved by technology

Traditional cooling fans generate cooling airflow by rotating their blades. The design of the fan blades makes it impossible to effectively reduce the thickness, which does not meet the current thin and light design trend of portable electronic devices.
In addition, the traditional cooling fan consumes a lot of power when it is running, which reduces the power durability of portable electronic devices

Abstract

A heat dissipation device including a driving module and a heat dissipation sheet is provided. The heat dissipation sheet has a connection portion and a swing portion and is connected to the driving module by the connection portion. When the driving module receives an input voltage to drive the connection portion, the connection portion drives the swing portion to swing back and forth so as to generate a heat dissipation airflow.

Description

technical field [0001] The present invention relates to a heat dissipation device and its control method, and in particular to a heat dissipation device which uses the swing of the heat dissipation fin body to generate heat dissipation airflow and its control method. Background technique [0002] In recent years, with the development of the technology industry, portable electronic devices such as notebook computers (Notebook, NB), tablet computers (Tablet PC) and smart phones (Smart Phone) have become popular in the consumer market. As the operating performance of portable electronic devices continues to improve, the heating power of electronic components therein also increases continuously. [0003] In order to prevent temporary or permanent failure of electronic components due to overheating, or to avoid user discomfort due to overheating of the housing of the electronic device, most portable electronic devices are equipped with cooling fans for cooling. Traditional cooli...
