Therefore, a variety of cooling methods for wireless charging products have appeared in the market. The current main cooling method is to use a fan to directly blow air to cool down. Although it can have a certain cooling effect, the effect is not obvious and cannot solve the heat dissipation problem. Summary of the invention

[0003] In order to overcome the above-mentioned shortcomings, the present invention provides a vehicle-mounted wireless charging temperature control device and method, which can achieve heat dissipation during the wireless charging process of a mobile phone and has good heat dissipation and cooling effects.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: a vehicle-mounted wireless charging temperature control device, comprising a body, a flow channel is arranged in the body, a fan and a semiconductor refrigerator are installed in the flow channel, a hot air duct and a cold air duct are arranged on the semiconductor refrigerator, the hot surface of the semiconductor refrigerator faces the hot air duct, and the cold surface of the semiconductor refrigerator faces the cold air duct; a hot air outlet and a cold air outlet isolated from each other are arranged on the body, the hot air outlet is connected to the hot air duct, and the cold air outlet is connected to the cold air duct.

[0005] During the wireless charging process of the mobile phone, the fan and the semiconductor cooler are started, the air flow flows along the air duct and blows towards the hot air duct and the cold air duct. The temperature of the hot surface of the semiconductor cooler increases, and the temperature of the cold surface of the semiconductor cooler decreases. The high-temperature airflow formed in the hot air duct is discharged outward through the hot air outlet, and the low-temperature airflow formed in the cold air duct is transported to the wireless charging position of the mobile phone through the cold air outlet to dissipate heat and cool the mobile phone.

[0006] The airflow blowing toward the mobile phone in this application is a low-temperature airflow cooled by a semiconductor refrigerator, which has a good heat dissipation and cooling effect on the mobile phone, preventing the mobile phone from overheating during wireless charging. The vehicle-mounted wireless charging temperature control device of this application can achieve heat dissipation during the wireless charging process of the mobile phone, and has a good heat dissipation and cooling effect.

[0007] Preferably, the fan is a centrifugal fan.

[0008] The centrifugal fan is small in size and can be better used in the small space on the vehicle to change the wind direction and provide air volume to the hot and cold ends at the same time.

[0009] Preferably, a plurality of guide plates are arranged in the flow channel near the fan.

[0010] The guide plate plays a good role in guiding the air flow, making the air flow evenly distributed, while allowing the hot end air volume to be relatively large, matching the working characteristics of the semiconductor refrigerator that the heat generation is greater than the cooling capacity.

[0011] Preferably, a plurality of copper fins are installed on both the hot surface and the cold surface of the semiconductor refrigerator.

[0012] The copper fins have low thermal resistance and increase the heat exchange area, which is beneficial to improve the heat exchange effect and make the airflow cool down or heat up quickly.

[0013] Preferably, a thermal insulation sleeve is provided outside the semiconductor refrigerator.

[0014] The thermal insulation sleeve plays the role of heat insulation and vibration reduction. It can reduce the vibration of the flow channel and avoid vibration damage when used in a vehicle.

[0017] Preferably, a temperature sensor is installed in the semiconductor refrigerator.

[0018] The temperature sensor detects the temperature of the semiconductor refrigerator and can monitor the working status of the product in real time. If the temperature is abnormal, the device can alarm or cut off the power supply to avoid damage to the product due to excessive temperature.

[0019] Preferably, the machine body comprises an upper shell and a lower shell, and the upper shell and the lower shell are sealed and butted against each other.

[0020] The machine body is assembled from an upper shell and a lower shell, which is convenient for processing. The upper shell and the lower shell are sealed and butted to form a flow channel, which facilitates the installation of semiconductor refrigerators and fans.

[0021] Preferably, the cold air outlet is connected to the wireless charging loading plate, a ventilation ring cavity is arranged on the edge of the wireless charging loading plate, the cold air outlet is connected to the ventilation ring cavity, a plurality of circles of sinking grooves are arranged on the upper surface of the wireless charging loading plate, a plurality of flow holes are arranged at circumferential intervals inside the wireless charging loading plate, an air outlet is arranged at the bottom of the sinking groove, and the air outlet and the flow hole are connected.

[0022] When the mobile phone is wirelessly charged, the mobile phone is placed on the wireless charging loading plate, and the low-temperature airflow outputted from the cold air outlet is transported to the ventilation ring cavity, discharged from the air outlet after passing through the flow hole, and blown to the mobile phone to dissipate heat and cool the mobile phone. A plurality of circles of sinking grooves are arranged on the upper surface of the wireless charging loading plate, so that there is a gap between the mobile phone and the upper surface of the wireless charging loading plate, thereby increasing the area of ​​the mobile phone swept by the airflow, which is conducive to improving the heat dissipation and cooling effect of the mobile phone.

[0023] A vehicle-mounted wireless charging temperature control method is operated by using a vehicle-mounted wireless charging temperature control device to start a fan and a semiconductor refrigerator. The fan blows air to the hot air duct and the cold air duct, the hot surface temperature of the semiconductor refrigerator increases, and the cold surface temperature of the semiconductor refrigerator decreases. The high-temperature airflow formed in the hot air duct is discharged outward through the hot air outlet, and the low-temperature airflow formed in the cold air duct is transported to the wireless charging position of a mobile phone through the cold air outlet to dissipate heat and cool the mobile phone.

[0024] When the mobile phone is wirelessly charged in the car, the mobile phone is placed on the wireless charging loading plate. The temperature of the air flow blown by the fan to the cold surface of the thermoelectric semiconductor is reduced, forming a low-temperature air flow. The low-temperature air flow blows toward the mobile phone to dissipate heat and cool the mobile phone, with a good cooling effect.

[0057] When the mobile phone is wirelessly charged, the mobile phone is placed on the wireless charging loading plate 22, and the low-temperature airflow output by the cold air outlet 13 is delivered to the ventilation ring cavity 23, and then discharged from the air outlet 26 after passing through the flow hole 25, and blown to the mobile phone to dissipate heat and cool the mobile phone. A plurality of circles of sinking grooves 24 are arranged on the upper surface of the wireless charging loading plate 22, so that there is a gap between the mobile phone and the upper surface of the wireless charging loading plate 22, thereby increasing the area of ​​the mobile phone swept by the airflow, which is conducive to improving the heat dissipation and cooling effect of the mobile phone.

[0058] A flow regulating plate 30 is installed in the flow channel 2, and one end of the flow regulating plate 30 is rotatably installed between the hot air channel 6 and the cold air channel 7. A movable regulating block 31 is installed on the side wall of the flow channel 2, and a slide groove 32 is arranged on the regulating block 31. A slide column 33 is arranged on the flow regulating plate 30, and the slide column 33 is movably inserted in the slide groove 32. An adjusting motor 34 is installed on the inner wall of the flow channel 2. The output shaft of the adjusting motor 34 is connected to the screw rod 35, and the screw rod 35 is threadedly connected to the adjusting block 31. When the adjusting motor 34 works, the screw rod 35 is driven to rotate, thereby driving the adjusting block 31 to move, and then driving the flow regulating plate 30 to rotate, so as to adjust the flow rate of the airflow blown into the hot air channel 6 and the cold air channel 7. A guide groove 36 is arranged on the side wall of the flow channel 2, and the adjusting block 31 is slidably installed in the guide groove 36. The adjusting motor 34 is installed at one end of the guide groove 36. During actual operation, the heat generated by the semiconductor refrigerator 4 is greater than its cooling capacity, so the hot surface requires a larger airflow. At this time, the size of the air inlet opening is adjusted by rotating the flow regulating plate 30, thereby adjusting the air flow rate blown into the hot air duct 6 and the cold air duct 7, thereby increasing the airflow entering the hot air duct 6 and reducing the airflow entering the cold air duct 7, so that the heat can be discharged quickly.

[0059] A vehicle-mounted wireless charging temperature control method is operated by using a vehicle-mounted wireless charging temperature control device to start the fan 3 and the semiconductor refrigerator 4. The fan 3 blows air to the hot air duct 6 and the cold air duct 7 at the same time. The hot surface temperature of the semiconductor refrigerator 4 increases to form hot air in the hot air duct 6, and the cold surface temperature of the semiconductor refrigerator 4 decreases to form cold air in the cold air duct 7. The high-temperature airflow formed in the hot air duct 6 is discharged outward through the hot air outlet 12, and the low-temperature airflow formed in the cold air duct 7 is transported to the mobile phone wireless charging position through the cold air outlet 13 to dissipate heat and cool the mobile phone. In this embodiment, the low-temperature airflow formed in the cold air duct 7 is transported to the ventilation ring cavity 23 of the wireless charging loading plate 22 through the cold air outlet 13, and is discharged from the air outlet 26 after passing through the flow hole 25, and blows to the mobile phone to dissipate heat and cool the mobile phone. A plurality of circles of sinking grooves 24 are arranged on the upper surface of the wireless charging loading plate 22, so that there is a gap between the mobile phone and the upper surface of the wireless charging loading plate 22, thereby increasing the area of ​​the airflow sweeping the mobile phone, which is conducive to improving the heat dissipation and cooling effect of the mobile phone.

[0060] When the mobile phone is wirelessly charged in the car, the mobile phone is placed on the wireless charging loading plate 22, and the temperature of the air flow blown by the fan 3 to the cold surface of the thermoelectric semiconductor is reduced, forming a low-temperature air flow, and the low-temperature air flow blows to the mobile phone to dissipate heat and cool the mobile phone, with a good cooling effect.
