AI Technical Summary

Technical Problem

Existing heat dissipation drivers exhibit high airflow velocity but low total flow rate under high load conditions, resulting in obstructed airflow channels, affecting unidirectional sealing performance and heat dissipation stability, and making it difficult to meet the heat dissipation requirements of electronic devices.

Method used

A heat dissipation actuator was designed, which includes a vibration system and a flow regulation component. By using the cooperation between the cover plate and the connecting hole, the vibration system generates a pressure difference to control the unidirectional flow of air. A balance hole is set on the cover plate to buffer the air pressure difference, prevent the cover plate from deflecting, and ensure stable airflow.

Benefits of technology

It achieves stable unidirectional airflow, improves heat dissipation efficiency, maintains a good heat dissipation effect, and adapts to the heat dissipation requirements under high load operation.

Abstract

The application relates to the technical field of electronic equipment heat dissipation, and discloses a heat dissipation driver and electronic equipment, the heat dissipation driver comprising a frame, a vibration system, the outer edge of the vibration system being connected with the frame, and a communication hole being formed in the vibration system, a driving system for driving the vibration system to vibrate along the axial direction of the communication hole, and a flow adjusting assembly comprising a cover plate and a supporting leg which are connected with each other, the end of the supporting leg away from the cover plate being connected with the vibration system, the supporting leg having a flexible supporting part capable of being deformed, the cover plate being arranged opposite to the communication hole, and a balance hole smaller than the communication hole being formed in the cover plate; wherein when the vibration system moves towards a first side surface direction, the cover plate covers the communication hole; and when the vibration system moves towards a second side surface direction opposite to the first side surface, the cover plate is separated from the vibration system. The heat dissipation driver can effectively avoid the deflection of the cover plate during the working process, thereby ensuring the one-way stable flow of air flow, improving the heat dissipation efficiency, and maintaining a better heat dissipation effect.
