Description

Technical Field

[0021] In the above structure, the heat-conducting body 1 is used to accommodate the charging coil module 3, the annular magnetic attraction component 4 and the semiconductor cooling sheet 5. The charging coil module 3 is used to radiate electromagnetic energy to the coil module in the mobile phone. The annular magnetic attraction component 4 is used to magnetically match with the built-in or external iron ring or magnetic ring of the mobile phone, so as to adsorb the mobile phone on the heat-conducting top cover 2. On this basis, a heat-conducting rubber sheet 6 is provided at the center of the charging coil module 3. The top surface of the heat-conducting rubber sheet 6 is in contact with the heat-conducting top cover 2 to ensure reliable heat transfer. The bottom surface of the heat-conducting rubber sheet 6 is directly or indirectly in contact with the cold end surface of the semiconductor cooling sheet 5. At the same time, the heat-conducting rubber sheet 6 is in contact with the cold end surface of the semiconductor cooling sheet 5. The hot end face is in contact with the heat-conducting main body 1. When the semiconductor cooling sheet 5 is powered on, its cold end face exchanges heat with the back of the mobile phone through the heat-conducting adhesive film 6 and the heat-conducting top cover 2.

For details, see Figure 1 When the bottom surface of the charging coil module 3 is covered with a metal bottom plate, the metal bottom plate can be bonded between the thermally conductive film 6 and the hot end surface of the semiconductor cooling film 5. At this time, the thermally conductive film 6 and the semiconductor cooling film 5 are in an indirect bonding relationship.
