Title:
TERMINAL ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/103807
Kind Code:
A1
Abstract:
The present application provides a terminal electronic device. The terminal electronic device comprises a middle frame, a circuit mainboard, and a heat dissipation assembly. The middle frame comprises a body and at least one heat conduction portion, the circuit mainboard and the heat dissipation assembly are installed on the body, and the heat conduction portion is connected to the body. The heat dissipation assembly comprises a heat conduction member and a fan, and the heat conduction member abuts against the circuit mainboard and the heat conduction portion. Heat of the circuit mainboard is transmitted to the heat conduction portion by means of the heat conduction member; because the heat conduction portion is connected to the body of the middle frame, the heat continues to be transmitted to the body from the heat conduction portion; moreover, the body is in direct contact with an external environment of the terminal electronic device, and has a large area, such that large-area heat dissipation can be achieved by means of the body. The fan can accelerate the flowing of air around the heat conduction portion, such that the heat of the heat conduction portion can be quickly transmitted to the surrounding air, thereby improving the heat dissipation efficiency. The terminal electronic device of the present application reduces the heat of the circuit mainboard in two ways of natural heat dissipation and active heat dissipation.
