Abstract

The invention discloses an electronic device heat dissipation device based on an ultrasonic energy converter. The electronic device heat dissipation device comprises one or multiple ultrasonic energyconverters arranged to close to a heat source formed by the electronic device; the ultrasonic energy converter is used for forming acoustic streaming in a disturbance way to perform heat dissipation on the electronic device; on the one hand, the ultrasonic energy converter is used as the power component of a heat exchange medium, so that the produced ultrasonic wave can disturb the heat exchange medium so as to form the acoustic streaming flowing through the electronic device heat source; compared with the traditional air-cooling and liquid-cooling and like heat dissipation way, the heat dissipation device has the advantages of being low in power consumption, silent, insensitive to the dust and high in reliability; on the other hand, the heat dissipation device can work as normal by arranging the ultrasonic energy converter on a medium channel passing through the heat source and through the supporting of a simple control circuit; the heat dissipation device has the features of being convenient for layout and simple in circuit, and the heat dissipation can be applied to the integrated circuit under multiple environments.

Description

technical field [0001] The invention relates to the technical field of semiconductor device heat dissipation, in particular to an electronic device heat dissipation device based on an ultrasonic transducer. Background technique [0002] With the development of integration technology and microelectronic packaging technology, the total power density of electronic devices continues to increase, while the physical size of electronic devices and electronic equipment tends to be smaller and miniaturized, and the heat generated accumulates rapidly, causing The heat flux density is also increasing, so the high temperature environment will definitely affect the performance of electronic devices and equipment, which requires a more efficient thermal control scheme. At present, the heat dissipation problem of electronic devices has evolved into a major focus of electronic devices and electronic equipment manufacturing. For example, in applications such as electric vehicles, smart grids...
