Problems solved by technology

In addition, due to the special structure of the tablet computer, a certain air intake height must be ensured in order to increase the air volume, so that the total thickness of the tablet computer cannot be too thin, which is not conducive to the thin and light design of the tablet computer

Abstract

The invention provides a piezoelectric fan, a radiator and electronic equipment. The electric fan comprises an air blowing device, and the blowing device comprises vibrating pieces and piezoelectric elements which are contained on the vibrating pieces. The blowing device further comprises an air blowing space and an air outlet communicated with the air blowing space, the air blowing space is formed by connecting the vibrating pieces with each other and then surrounding the vibrating pieces, and the piezoelectric elements can drive the vibration piece to vibrate so as to generate air flow. Thepiezoelectric elements are arranged on the vibrating pieces, and the piezoelectric elements can drive the vibration pieces to vibrate to generate an air flow which can meet the heat dissipation requirement, so that no extra air inlet space is needed, the structure is simple, the occupied space is small, and the light and thin design of the electronic equipment is facilitated.

Description

technical field [0001] The present disclosure relates to the technical field of heat dissipation, and in particular to a piezoelectric fan, a radiator and electronic equipment. Background technique [0002] The heat dissipation method of the tablet computer is to use the heat pipe to conduct the heat from the heat source to the structural parts, and then use the natural convection to transfer the heat in the structural parts to the air. When the power of the heat source is high, the heat pipe is used to transfer the heat to the heat dissipation fins, and then the centrifugal fan is used to blow and cool the heat dissipation fins, so that the heat is discharged from the casing of the tablet computer. [0003] Since the centrifugal fan is side air intake, it will be affected by the casing. At the same time, due to appearance requirements, holes cannot be opened on the side of the casing (that is, facing the air inlet of the centrifugal fan), so it is necessary to ensure a cer...
