Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] This utility model provides, for example Figure 1 The fast-charging intelligent cooling in-vehicle wireless charger shown includes a main body 100, a connecting ball 200, and a suspension part 300. The main body 100 includes a cover 110. A magnet 120 is connected to the inner wall of the upper side of the cover 110. A coil 121 is connected to the inner wall of the magnet 120. A cooling plate 122 is provided on the right side of the coil 121. A PC sheet 123 is connected to the right side of the cooling plate 122. A main PCB 140 is connected to the right side of the PC sheet 123. A TEC semiconductor 130 is connected to the upper side of the main PCB 140. Thermal conductive silicone 131 is connected to the left and right sides of the TEC semiconductor 130, respectively. A ribbon cable 141 is connected to the lower side of the main PCB 140. The ribbon cable 141 is connected to a TYPEC interface 142. The input end of the coil 121 is connected to the main PCB 140.

[0014] The cover 110 is fixed to the magnet 120 and the coil 121 by applying AB glue and applying pressure. Then, the coil 121 is attached to the cooling plate 122 and screws are tightened to fix the cooling plate 122, PC sheet 123 and main PCB 140 in sequence. The TEC semiconductor 130 is attached to the thermal silicone 131 and then soldered to the main PCB. The TYPEC interface 142 can be connected to the charging cable and the car power interface, using the car power as the power input.

[0015] In some specific embodiments of this utility model, the main PCB 140 is connected to the heat sink base 151 on the right side, the heat sink base 151 is connected to the heat sink 150 on the right side, the heat sink 150 is provided with a fan 152 inside and connected to the right surface of the heat sink base 151, the fan 152 is provided with a middle frame 161 on the right side, the middle frame 161 is provided with an air duct foam 160 on the left side inside, the middle frame 161 is provided with a dustproof net 162 and a middle frame base 163 on the right side, the middle frame 161 is connected to the face cover 110 on the left side, the middle frame base 163 is connected to a connecting ball 200 on the right side, and the connecting ball 200 is connected to a suspension part 300 on the right side.

[0019] The specific principle is as follows: When current passes through the TEC semiconductor 130, electrons randomly jump inside the material, causing local vibration and raising the local temperature. At the same time, on the other side, due to the Peltier effect, the exchange of hot and cold electrons causes the temperature on that side to drop. Then, the fan further cools the surface. This hot and cold exchange is controlled in a stable cycle, thereby achieving a cooling effect. This allows Apple phones to be quickly charged at an ambient temperature of 30°C or above, shortening the charging time.
