Title:
HEAT DISSIPATION STRUCTURE AND ELECTRONIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/093335
Kind Code:
A1
Abstract:
The present application provides a heat dissipation structure and an electronic apparatus. The heat dissipation structure can comprise a circuit board, magnetic devices, a heat sink, and a heat-conducting medium, wherein the magnetic devices can be positioned between the circuit board and the heat sink. Each magnetic device can comprise a magnetic core and film-covered wires, wherein the magnetic core comprises a stop portion and a central magnetic column which are fixedly connected; and the film-covered wires are wound around the central magnetic column and are electrically connected to the circuit board. In the heat dissipation structure, at least part of a side face of each stop portion can be provided with a heat-conducting film, such that the temperature uniformity of the magnetic devices can be effectively improved, so as to solve the problem of local high temperatures of the magnetic devices. In addition, the heat-conducting medium can be arranged between the magnetic devices and the heat sink, and the heat-conducting medium and some of the magnetic devices are in heat-conducting contact with the heat sink, such that heat generated by the magnetic devices can be conducted to the heat-conducting medium and then transferred to the heat sink for heat dissipation; therefore, the heat dissipation efficiency of the heat dissipation structure can be effectively improved, and the performance of the electronic apparatus provided with the heat dissipation structure can thus be improved.
