[0002] With the rapid development of the automotive industry, wireless charging for electronic devices has become a common feature in various car models. It can provide wireless charging services for portable electronic devices such as mobile phones, tablets, and smartwatches. With its convenience of simply placing the device on the ground to charge, it eliminates the need for passengers to carry data cables, effectively avoiding cluttered cables in the car and keeping the interior tidy. It is also compatible with different brands of electronic devices, eliminating the need to distinguish between charging interface types, and can reduce the potential risk of spontaneous combustion caused by aging or short circuits in data cables. It is especially suitable for charging needs in short-distance commuting or frequent car use scenarios. Therefore, the market's reliance on in-vehicle wireless charging devices continues to increase, and in order to meet users' pursuit of charging efficiency, the wireless charging power is also showing a gradual upward trend.

[0003] In related technologies, most cooling methods for the heat generated by in-vehicle wireless charging devices during charging are semiconductor cooling or fan-assisted heat dissipation. Semiconductor cooling uses semiconductor components to achieve heat exchange and reduce temperature, while fan-assisted heat dissipation uses a fan to accelerate airflow and remove heat from the vicinity of the wireless charging device, thereby alleviating the overheating problem.

[0004] However, semiconductor cooling is prone to failure due to overheating of semiconductor components. In addition, its structure is complex and the manufacturing process is demanding. It is also susceptible to factors such as temperature and humidity in the vehicle interior, resulting in a high failure rate and poor reliability. It is difficult to adapt to the continuous heat dissipation requirements of wireless charging devices after the power is increased. Fan-type cooling requires a large-power fan, and the fan is usually located in the instrument panel. When running, it will generate obvious noise, which seriously affects the comfort experience of passengers in the vehicle. Summary of the Invention

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

[0021] With the rapid development of the automotive industry, wireless charging for electronic devices has become a common feature in various car models. It can provide wireless charging services for portable electronic devices such as mobile phones, tablets, and smartwatches. With its convenience of simply placing the device on the ground to charge, it eliminates the need for passengers to carry data cables, effectively avoiding cluttered cables in the car and keeping the interior tidy. It is also compatible with different brands of electronic devices, eliminating the need to distinguish between charging interface types, and can reduce the potential risk of spontaneous combustion caused by aging or short circuits in data cables. It is especially suitable for charging needs in short-distance commuting or frequent car use scenarios. Therefore, the market's reliance on in-vehicle wireless charging devices continues to increase, and in order to meet users' pursuit of charging efficiency, the wireless charging power is also showing a gradual upward trend.

[0022] Most in-vehicle wireless charging devices employ either semiconductor cooling or fan-assisted heat dissipation to address the heat generated during charging. Semiconductor cooling uses semiconductor components to exchange heat and lower the temperature, while fan-assisted heat dissipation uses a fan to accelerate airflow and remove heat from the vicinity of the wireless charging device, thus alleviating the overheating problem.

[0023] However, semiconductor cooling is prone to failure due to overheating of semiconductor components. In addition, its structure is complex and the manufacturing process is demanding. It is also susceptible to factors such as temperature and humidity in the vehicle interior, resulting in a high failure rate and poor reliability. It is difficult to adapt to the continuous heat dissipation requirements of wireless charging devices after the power is increased. Fan-type cooling requires a large-power fan, and the fan is usually located in the instrument panel. When running, it will generate obvious noise, which seriously affects the comfort experience of passengers in the vehicle.

[0024] This application provides an in-vehicle wireless charging cooling component, an in-vehicle refrigerator cooling system, a vehicle, and a method, which can solve the technical problems of traditional semiconductor cooling, which is prone to failure due to overheating, complex structure, high manufacturing process requirements, and fan-type heat dissipation, which generates obvious noise and seriously affects the comfort experience.

[0025] Firstly, such as Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, this application embodiment provides a vehicle-mounted wireless charging cooling component, which includes: a cooling plate 12, which is disposed below the wireless charging device 10; a high-pressure refrigerant pipe 7 and a low-pressure refrigerant pipe 8, one end of the high-pressure refrigerant pipe 7 being connected to the input end of the cooling plate 12, one end of the low-pressure refrigerant pipe 8 being connected to the output end of the cooling plate 12, and the other ends of the high-pressure refrigerant pipe 7 and the low-pressure refrigerant pipe 8 being connected to the vehicle-mounted refrigerator cooling circuit; and a control valve 9, which is installed on the high-pressure refrigerant pipe 7 to control the refrigerant flow rate through the high-pressure refrigerant pipe 7 in the vehicle-mounted refrigerator cooling circuit.

[0026] In this embodiment, the cooling plate 12 is configured to be located below the wireless charging device 10 to form a heat conduction connection with the wireless charging device 10; one end of the high-pressure refrigerant pipe 7 of the cold plate is connected to the input end of the cooling plate 12, and the other end of the high-pressure refrigerant pipe 7 of the cold plate is configured to be connected to the refrigeration circuit of the vehicle refrigerator; one end of the low-pressure refrigerant pipe 8 of the cold plate is connected to the output end of the cooling plate 12, and the other end of the low-pressure refrigerant pipe 8 of the cold plate is configured to be connected to the refrigeration circuit of the vehicle refrigerator, so as to construct a refrigerant flow path connected to the refrigeration circuit of the vehicle refrigerator through the high-pressure refrigerant pipe 7, the cooling plate 12, and the low-pressure refrigerant pipe 8 of the cold plate; the control valve 9 is installed on the high-pressure refrigerant pipe 7 of the cold plate, and the control valve 9 is configured to adjust the refrigerant flow rate entering the cooling plate 12 through the high-pressure refrigerant pipe 7 of the cold plate, thereby controlling the cooling intensity of the cooling plate 12 on the wireless charging device 10. This vehicle-mounted wireless charging cooling component reuses the cold source of the vehicle refrigerator's cooling circuit, achieving continuous cooling of the wireless charging device 10 without relying on semiconductor cooling components. This effectively avoids the high failure rate caused by overheating and complex structure of semiconductor cooling components. At the same time, it eliminates the need for a high-power fan, avoiding the impact of fan noise on the comfort of passengers in the vehicle. Furthermore, it adapts to the continuous heat dissipation requirements after the increase in wireless charging power, ensuring that the wireless charging device 10 maintains a stable working state during efficient charging.

[0027] In conjunction with the first aspect, in one implementation, such as Figure 5 As shown, the vehicle-mounted wireless charging cooling assembly also includes a heat spreader 11, which is disposed above the cooling plate 12 and below the wireless charging device 10.

[0028] In this embodiment, the heat spreader 11 is disposed above the cooling plate 12 and below the wireless charging device 10 to receive the heat generated when the wireless charging device 10 is working and to evenly conduct the heat to the cooling plate 12 below. Through the heat conduction cooperation between the heat spreader 11 and the cooling plate 12, the cooling effect of the cooling plate 12 on the wireless charging device 10 is made more uniform, further adapting to the heat dissipation requirements of concentrated heat after the wireless charging power is increased, and ensuring the overall temperature stability of the wireless charging device 10.

[0029] In conjunction with the first aspect, in one embodiment, the heat spreader 11 is equipped with a temperature sensor for collecting temperature information of the wireless charging device 10.

[0030] In this embodiment, in conjunction with the first aspect, in one implementation, multiple ribs 15 are provided at intervals on the relatively inner sidewalls of the water accumulation shell 13. The multiple ribs 15 extend along the vehicle height direction and abut against the sidewall of the cooling plate 12.

[0031] In conjunction with the first aspect, in one implementation, such as Figure 7As shown, the vehicle-mounted wireless charging cooling assembly also includes: a water-collecting housing 13, with a cooling plate 12 disposed inside the water-collecting housing 13; and a drain pipe 14, one end of which is connected to the water-collecting housing 13, and the other end of which extends to the outside of the vehicle.

[0032] In this embodiment, the cooling plate 12 is disposed inside the water collection shell 13. The water collection shell 13 is used to support the cooling plate 12 and to collect the condensate generated by the cooling plate 12 during the cooling process. One end of the drain pipe 14 is connected to the water collection shell 13, and the other end of the drain pipe 14 extends to the outside of the vehicle to drain the condensate collected in the water collection shell 13 to the outside of the vehicle. This prevents the condensate from accumulating in the water collection shell 13 and affecting the normal operation of the cooling plate 12 or the surrounding components of the vehicle wireless charging cooling component, thus ensuring the overall stability of the component operation.

[0033] In conjunction with the first aspect, in one implementation, such as Figure 7 As shown, multiple ribs 15 are spaced apart on the relatively inner sidewalls of the water accumulation shell 13. The multiple ribs 15 extend along the height direction of the vehicle body and abut against the sidewall of the cooling plate 12.

[0034] In this embodiment, the water-collecting housing 13 is used to support the cooling plate 12, and multiple ribs 15 are spaced apart on the relatively inner sidewalls of the water-collecting housing 13. The multiple ribs 15 extend along the height direction of the vehicle body, and abut against the sidewall of the cooling plate 12. Through the abutment and cooperation between the multiple ribs 15 and the sidewall of the cooling plate 12, the installation position of the cooling plate 12 in the water-collecting housing 13 can be positioned and fixed, so as to avoid the cooling plate 12 from shifting due to vibration during vehicle driving, which would affect the heat conduction efficiency with the wireless charging device 10. At the same time, it does not interfere with the function of the water-collecting housing 13 in collecting the condensate generated during the cooling process of the cooling plate 12, thus ensuring the overall stability of the vehicle wireless charging cooling component.

[0035] In conjunction with the first aspect, in one implementation, such as Figure 7 As shown, along the height of the vehicle body, the inner diameter of the bottom part of the water accumulation shell 13 gradually decreases.

[0036] In this embodiment, along the height of the vehicle body, the inner diameter of the bottom part of the water accumulation shell 13 gradually decreases. This structure can guide the condensate collected in the water accumulation shell 13 to converge at the bottom, avoid the condensate from being locally retained inside the shell, ensure that the condensate can be efficiently discharged in the future, and maintain a dry environment in the bottom area of ​​the cooling plate 12, so as to avoid the heat conduction efficiency of the cooling plate 12 and the overall operational stability of the component due to the accumulation of condensate.

[0037] Secondly, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, this application embodiment provides a vehicle refrigerator refrigeration system, which includes: a vehicle refrigerator refrigeration circuit, which is sequentially connected to a vehicle refrigerator compressor, a vehicle refrigerator cold plate, and a vehicle refrigerator heat dissipation device; a refrigeration plate 12, which is used to be disposed below a wireless charging device 10; a cold plate high-pressure refrigerant pipe 7 and a cold plate low-pressure refrigerant pipe 8, one end of the cold plate high-pressure refrigerant pipe 7 is connected to the input end of the refrigeration plate 12, one end of the cold plate low-pressure refrigerant pipe 8 is connected to the output end of the refrigeration plate 12, and the other ends of the cold plate high-pressure refrigerant pipe 7 and the other end of the cold plate low-pressure refrigerant pipe 8 are connected to the vehicle refrigerator refrigeration circuit, so that the refrigeration plate 12 and the vehicle refrigerator cold plate are connected in parallel; and a control valve 9, which is connected in series with the cold plate high-pressure refrigerant pipe 7 to control the refrigerant flow rate of the vehicle refrigerator refrigeration circuit through the cold plate high-pressure refrigerant pipe 7.

[0038] In this embodiment, the vehicle refrigerator refrigeration circuit is sequentially connected to the vehicle refrigerator compressor, the vehicle refrigerator cold plate, and the vehicle refrigerator heat dissipation device to form the vehicle refrigerator's own refrigeration cycle. The refrigeration plate 12 is configured to be located below the wireless charging device 10 for cooling and heat dissipation. One end of the cold plate high-pressure refrigerant pipe 7 is connected to the input end of the refrigeration plate 12, and the other end of the cold plate high-pressure refrigerant pipe 7 is connected to the vehicle refrigerator refrigeration circuit. One end of the cold plate low-pressure refrigerant pipe 8 is connected to the output end of the refrigeration plate 12, and the other end of the cold plate low-pressure refrigerant pipe 8 is connected to the vehicle refrigerator refrigeration circuit. This connection method allows the refrigeration plate 12 and the vehicle refrigerator cold plate to be arranged in parallel, realizing the diversion of the cold source of the vehicle refrigerator refrigeration circuit to the refrigeration plate 12. The control valve 9 is connected in series with the cold plate high-pressure refrigerant pipe 7. The control valve 9 is configured to adjust the refrigerant flow rate in the vehicle refrigerator refrigeration circuit that flows through the cold plate high-pressure refrigerant pipe 7 into the refrigeration plate 12, thereby controlling the cooling intensity of the refrigeration plate 12 on the wireless charging device 10. The vehicle refrigerator cooling system reuses the cold source of the vehicle refrigerator cooling circuit by connecting the cooling plate 12 and the vehicle refrigerator cold plate in parallel. It can provide continuous cooling for the wireless charging device 10 without the need for additional semiconductor cooling components or high-power fans. This effectively avoids the problems of overheating failure of semiconductor cooling components, high failure rate caused by complex structure, and noise from fan operation. At the same time, it adapts to the heat dissipation requirements after the increase in wireless charging power, ensuring the stable operation of the cooling functions of the wireless charging device 10 and the vehicle refrigerator.

[0039] Thirdly, such as Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, this application embodiment provides a vehicle, which includes the vehicle refrigerator refrigeration system mentioned above, and further includes: a sub-dashboard 1, on which a wireless charging panel 3 is provided; and a wireless charging device 10, which is disposed below the wireless charging panel 3.

[0040] In this embodiment, a wireless charging panel 3 is provided on the sub-dashboard 1. The wireless charging panel 3 is used for placing electronic devices to be charged to trigger wireless charging. The wireless charging device 10 is located below the wireless charging panel 3 to transmit power to the electronic devices placed on it through the wireless charging panel 3 to achieve wireless charging. The cooling plate 12 in the aforementioned vehicle refrigerator cooling system is correspondingly located below the wireless charging device 10. The refrigerant circulation of the vehicle refrigerator cooling system provides cooling and heat dissipation for the wireless charging device 10, ensuring that the wireless charging device 10 can maintain a stable temperature state when working in the sub-dashboard 1 area, and adapt to the wireless charging needs of the electronic devices to be charged.

[0041] Fourthly, such as Figure 9 As shown in the figure, this application embodiment provides a cooling method for an in-vehicle wireless charging cooling component, which includes the following steps: S100: The operating temperature T1 of the vehicle wireless charging device 10 is collected in real time by the temperature sensor integrated in the heat sink 11, and a communication connection is established with the device to be charged through the wireless charging protocol to obtain the current charging power P and the current charging temperature T2 of the device to be charged. S200: Compare the current charging power P with the preset power threshold, take the maximum value between the operating temperature T1 of the vehicle wireless charging device 10 and the current charging temperature T2 as Tmax, and compare it with the preset temperature threshold. If the current charging power P > preset power threshold or Tmax > preset temperature threshold, then open the control valve 9 to control the refrigerant flow rate through the high-pressure refrigerant pipe 7 of the cold plate in the vehicle refrigerator refrigeration circuit.

[0042] In this embodiment, the operating temperature of the vehicle-mounted wireless charging device 10 is collected in real time by a temperature sensor integrated in the heat spreader 11 and recorded as T1. Simultaneously, a communication connection is established with the device to be charged via a wireless charging protocol. Based on this communication connection, the current charging power of the device to be charged is obtained and recorded as P, and the current charging temperature of the device to be charged is recorded as T2. The obtained current charging power P is compared with a preset power threshold. The maximum value between the operating temperature T1 of the vehicle-mounted wireless charging device 10 and the current charging temperature T2 of the device to be charged is taken and recorded as Tmax. Tmax is then compared with a preset temperature threshold. The values ​​are compared. If either "current charging power P > preset power threshold" or "Tmax > preset temperature threshold" is met, the control valve 9 is opened. The opening action of the control valve 9 controls the flow rate of refrigerant in the high-pressure refrigerant pipe 7 through the cold plate in the vehicle refrigerator refrigeration circuit, so that the refrigerant can enter the refrigeration plate 12 to cool the vehicle wireless charging device 10. This ensures that the vehicle wireless charging device 10 maintains a suitable temperature during the charging process, adapts to the heat dissipation requirements after the increase in wireless charging power, and does not rely on semiconductor cooling components or high-power fans, thus ensuring the stability of the cooling process and the comfort of the vehicle.

[0043] In conjunction with the fourth aspect, one implementation also includes the following steps: S300: Count the cumulative time for the charging power P to be greater than the preset power or Tmax to be greater than the preset temperature. If the cumulative time exceeds the preset time, increase the opening of the control valve 9 to increase the refrigerant flow in the cooling circuit.

[0044] In this embodiment, after the control valve 9 is opened, the cumulative time for which the condition "charging power P is greater than the preset power threshold or Tmax is greater than the preset temperature threshold" is continuously counted. If the cumulative time exceeds the predetermined time, the opening of the control valve 9 is increased to increase the flow rate of the refrigerant flowing through the high-pressure refrigerant pipe 7 of the cold plate in the cooling circuit, further enhancing the cooling intensity of the cooling plate 12 on the vehicle wireless charging device 10, ensuring that the vehicle wireless charging device 10 can maintain a stable working state while continuously meeting the heat generation conditions, adapting to the heat dissipation requirements of continuous high-power operation during wireless charging, and without the need for additional cooling components, ensuring the targeted and efficient cooling regulation.

[0045] Here, the technical solutions provided in the embodiments of this application are described in full as follows: I. System Composition and Structural Relationships (I) Overall Layout Installation carrier and charging infrastructure: A wireless charging panel 3 is installed on the sub-dashboard 1, and a wireless charging device 10 is arranged below the wireless charging panel 3. The wireless charging device 10 is used to transmit power to the device to be charged (such as mobile phone, tablet, smartwatch) placed on it through the wireless charging panel 3. The vehicle refrigerator 2 is also arranged in the sub-dashboard 1 area. It has its own refrigerator refrigerant high pressure pipe 5 and refrigerator refrigerant low pressure pipe 6, which constitute the refrigeration cycle loop of the vehicle refrigerator 2.

[0046] Cooling core component integration: The vehicle-mounted wireless charging cooling component 4 is the cooling core, which is linked with the wireless charging device 10 and the vehicle-mounted refrigerator 2 cooling circuit. Specifically, it includes a heat spreader 11, a cooling plate 12, a high-pressure refrigerant pipe 7 for the cold plate, a low-pressure refrigerant pipe 8 for the cold plate, a control valve 9, and a water accumulation shell 13, a drain pipe 14 and a rib 15 for condensate management.

[0047] (II) Detailed Composition and Connection Relationship of Vehicle-Mounted Wireless Charging Cooling Component 4 Heat conduction and heat dissipation structure: The heat dissipation plate 11 is located below the wireless charging device 10 and above the cooling plate 12, forming a heat conduction cooperation with both the wireless charging device 10 and the cooling plate 12; the heat dissipation plate 11 is a vacuum cavity made of copper, with a multi-layer copper mesh microstructure attached to the inner wall. The microstructure adopts a regionalized hole size design, which can bear the heat generated by the wireless charging device 10 and achieve uniform conduction, avoiding local heat accumulation; the heat dissipation plate 11 integrates a temperature sensor, which can collect the operating temperature of the wireless charging device 10 in real time.

[0048] Refrigeration and heat exchange structure: The refrigeration plate 12 is a heat exchanger similar to an evaporator, consisting of flat tubes and fins. Refrigerant flows inside the flat tubes, and the fins increase the heat exchange area. The refrigeration plate 12 is located below the heat exchange plate 11 and is used to receive the heat transferred by the heat exchange plate 11 and achieve cooling through heat exchange with the refrigerant.

[0049] Refrigerant circuit connection structure: One end of the high-pressure refrigerant pipe 7 of the cold plate is connected to the input end of the refrigeration plate 12, and the other end is connected to the refrigeration circuit where the high-pressure refrigerant pipe 5 of the vehicle refrigerator 2 is located; one end of the low-pressure refrigerant pipe 8 of the cold plate is connected to the output end of the refrigeration plate 12, and the other end is connected to the refrigeration circuit where the low-pressure refrigerant pipe 6 of the vehicle refrigerator 2 is located. Through the above connection, the refrigeration plate 12 and the refrigeration circuit of the vehicle refrigerator 2 are connected in parallel to realize the reuse of cold source; the control valve 9 is connected in series with the high-pressure refrigerant pipe 7 of the cold plate to control the refrigerant flow rate of the vehicle refrigerator 2 through the high-pressure refrigerant pipe 7 of the cold plate, thereby regulating the refrigeration intensity of the refrigeration plate 12.

[0050] Condensate management structure: The water collection shell 13 is used to support the cooling plate 12 and the heat spreader 11. Multiple ribs 15 extending along the vehicle height direction are arranged at intervals on its inner sidewalls. The multiple ribs 15 abut against the sidewall of the cooling plate 12, which can position and fix the cooling plate 12 to prevent it from shifting due to vehicle vibration and affecting heat transfer efficiency. One end of the drain pipe 14 is connected to the water collection shell 13, and the other end extends to the outside of the vehicle. It is used to drain the condensate generated during the cooling process of the cooling plate 12 from the water collection shell 13 to the outside of the vehicle to prevent the accumulation of condensate from affecting the operation of the components. Along the vehicle height direction, the inner diameter of the bottom part of the water collection shell 13 gradually decreases, which can guide the condensate to the bottom to converge and ensure drainage efficiency.

[0051] II. Refrigeration Control Methods Data acquisition steps: The operating temperature of the wireless charging device 10 is collected in real time by the temperature sensor integrated on the heat spreader 11; at the same time, a communication connection is established with the device to be charged through the wireless charging protocol to obtain the current charging power of the device to be charged and the charging temperature of the device itself.

[0052] Cooling start judgment steps: Compare the current charging power with the preset power threshold, take the maximum value between the operating temperature of the wireless charging device 10 and the charging temperature of the device to be charged, and compare the maximum value with the preset temperature threshold; if either the current charging power is greater than the preset power threshold or the maximum value is greater than the preset temperature threshold, then open the control valve 9, so that the refrigerant in the cooling circuit of the vehicle refrigerator 2 flows into the cooling plate 12 through the high-pressure refrigerant pipe 7 of the cold plate, and then flows back to the cooling circuit of the vehicle refrigerator 2 through the low-pressure refrigerant pipe 8 of the cold plate, thus starting the cooling of the wireless charging device 10.

[0053] Cooling intensity adjustment steps: After opening the control valve 9, continuously collect and update the current charging power, the operating temperature of the wireless charging device 10 and the charging temperature of the device to be charged, and count the cumulative time for the charging power to be greater than the preset power threshold or the maximum value to be greater than the preset temperature threshold. If the cumulative time exceeds the preset time, increase the opening of the control valve 9 to increase the refrigerant flow in the high-pressure refrigerant pipe 7 of the cold plate, further enhance the cooling intensity of the cooling plate 12, and ensure that the wireless charging device 10 maintains stable operation under continuous high heat generation.
