In-vehicle wireless charging devices provide convenient charging services for mobile devices through the principle of electromagnetic induction, avoiding the inconvenience of frequent plugging and unplugging required by traditional wired charging.

[0003] Existing in-vehicle wireless charging devices typically use fan cooling to cool the phone by blowing natural air through the fan. However, because wireless charging devices have noise requirements, the cooling efficiency cannot be increased by increasing the fan speed, resulting in only average heat dissipation effect.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0023] In the description of this application, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use, they are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0024] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0025] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0026] Please refer to Figure 1 , Figure 2 The embodiments of this application provide a cooling device, including an air pump 100, a vortex tube 200, and a receiving device 300. The vortex tube 200 is provided with a pipe inlet 210, a cold air outlet 220, and a hot air outlet 230. The air outlet of the air pump 100 is connected to the pipe inlet 210, and the cold air outlet 220 is connected to the receiving device 300 to dissipate heat from the receiving device 300. The hot air outlet 230 is used to connect to the external environment.

[0027] It should be understood that the vortex tube 200 is a device without moving parts that achieves hot and cold flow separation based on the principle of gas dynamics. Its operation depends on the high-speed rotation of high-pressure gas and the angular momentum exchange of the internal flow field, thereby generating and separating high-temperature and low-temperature airflows.

[0028] When the air pump 100 is running, it compresses the gas and delivers it to the pipe inlet 210 of the vortex tube 200. After the compressed gas enters the vortex tube 200, it forms a high-speed rotating airflow in the vortex chamber. The airflow heats up in the outer region due to friction and energy accumulation, forming a high-temperature airflow that flows towards the hot gas outlet 230. At the same time, part of the airflow rotates in the opposite direction under the action of pressure difference and flows towards the cold gas outlet 220. In this process, the airflow is cooled down through the exchange of momentum and heat, thereby outputting low-temperature cold air to the receiving device 300. This improves the heat dissipation efficiency compared to the fan 330 blowing natural wind directly.

[0029] This cooling equipment can provide a stable low-temperature air source without increasing noise, making it suitable for in-vehicle environments where quiet operation is crucial. For example, in an in-vehicle wireless charging scenario, where the receiver 300 functions as a wireless charging device, cool air enters the device through the cool air outlet 220, carrying away the operating temperature of the internal circuit board assembly 313 and blowing it towards the charging panel 311, thus achieving a cooling effect. In a seat usage scenario, where the receiver 300 functions as a seat, cool air enters the seat through the cool air outlet 220 and is then blown outwards, similarly achieving a cooling effect.

[0030] Please refer to Figures 3-6 In some embodiments, the receiving device 300 includes a main body 310, an inflatable plate 320, and a fan 330. The inflatable plate 320 and the fan 330 are both disposed on the main body 310. The inflatable plate 320 has a cooling pipe 321 inside, which is connected to the cold air outlet 220. The inflatable plate 320 has fins 322 on the outside, and the fan 330 is used to blow air toward the fins 322.

[0031] It should be noted that the blown plate 320 is a metal plate with a continuously curved cooling pipe 321 formed inside. The cooling pipe 321 can receive gas flow at a certain pressure. The fins 322 are formed on the outside of the blown plate 320, can be made of aluminum, and can be cooled synchronously with the blown plate 320.

[0032] Low-temperature gas output from the cold gas outlet 220 of the vortex tube 200 is introduced into the cooling pipe 321 inside the blown plate 320. When the low-temperature gas flows in the cooling pipe 321, the overall temperature of the blown plate 320 drops. Since the fins 322 are fixed to the outer surface of the blown plate 320, the fins 322 are cooled and become a low-temperature heat exchange structure.

[0033] When the fan 330 is started, the airflow generated by the fan 330 flows along the surface of the fins 322. This airflow is rapidly cooled during the heat exchange with the low-temperature fins 322, forming a low-temperature airflow that is then sent into the working area of ​​the receiving device 300, achieving the effect of ventilation and heat dissipation. Thus, the flow of cold air within the inflatable plate 320 achieves the first level of cooling, while the fins 322 and the fan 330 work together to produce a second level of cooling, forming a composite heat dissipation mode.

[0034] In an optional embodiment, the receiving device 300 is a wireless charging device. The main body 310 includes a charging panel 311, an inflatable plate 320 and a fan 330, all of which are disposed on one side of the charging panel 311. A first air outlet 3111 is provided on the charging panel 311 for discharging the air blown by the fan 330.

[0035] In the scenario where the receiver 300 is a wireless charging device, the blown plate 320 and the fan 330 are arranged together on the back of the charging panel 311. After the low-temperature gas enters the cooling pipe 321 inside the blown plate 320, it conducts the cold energy to the entire plate, thereby reducing its temperature. The fins 322 are cooled together with the blown plate 320.

[0036] It should be noted that the first air outlet 3111 is a through-hole structure penetrating the charging panel 311, which can be opened at the edge of the charging panel 311. The main body 310 can also be provided with a channel 312 to guide the air flow. This channel 312 is connected to the first air outlet 3111. The airflow generated by the fan 330 is blown through this channel 312 and the first air outlet 3111 to the working area on the front of the charging panel 311. The circuit board assembly 313 is disposed between the charging panel 311 and the blown plate 320. The blown plate 320 can simultaneously remove the heat of the circuit board assembly 313 while the overall cooling is being carried out, so as to ensure the normal operation of the circuit board assembly 313.

[0037] When the fan 330 is started, the airflow generated is cooled after passing through the fins 322. Then, the cooled airflow is directed to the working area on the front of the charging panel 311 through the first air outlet 3111 on the charging panel 311, thereby cooling the mobile phone located in the working area.

[0038] When the user places the phone on the charging panel 311 to start charging, the air pump 100 is activated to supply air, the vortex tube 200 outputs cold air into the blowing plate 320, and the fan 330 operates synchronously, so that the low-temperature airflow is continuously blown out from the first air outlet 3111 to dissipate heat from the phone placed on the charging panel 311.

[0039] In another alternative embodiment, please refer to Figures 7-10 The receiving device 300 is a seat, and the main body 310 includes a seat shell 314, an inflation plate 320 and a fan 330, both of which are disposed inside the seat shell 314. A second air outlet 3141 is provided on the seat shell 314 for discharging the air blown by the fan 330.

[0040] In the scenario where the receiving device 300 is a seat, the inflatable plate 320 and the fan 330 are integrated into the seat housing 314. The airflow generated by the fan 330 passes through the fins 322 and is guided to the seat surface, i.e. the human contact area of ​​the seat cushion or backrest, through the second air outlet 3141 opened on the seat housing 314, thereby achieving active ventilation and cooling on the occupant side.

[0041] The seat shell 314 has an installation space inside to accommodate components such as the blow-up plate 320 and the fan 330. The second air outlet 3141 is a through-hole structure that penetrates the wall of the seat shell 314 to enable communication between the cooling airflow inside the seat and the external seating space.

[0042] When the driver or passenger turns on the seat ventilation function, the cooling equipment starts, and low-temperature gas enters the inflatable plate 320 inside the seat. At the same time, the fan 330 operates, so that the cooling airflow is continuously discharged from the second air outlet 3141, improving the thermal and humid environment of the sitting area.

[0043] In some embodiments, the blown plate 320 is provided with an air inlet 323 and an air outlet 324 that are connected to the cooling pipe 321. The cold air outlet 220 is connected to the air inlet 323, and the air outlet 324 is connected to the air inlet of the air pump 100. Optionally, a connector is provided on the blown plate 320, and both the air inlet 323 and the air outlet 324 are located on the connector.

[0044] After the low-temperature gas flows out of the cold air outlet 220 of the vortex tube 200, it enters the air inlet 323 of the inflator 320 through the pipeline and flows along the internal cooling pipe 321. During this process, it exchanges heat with the external environment, absorbing heat from the inflator 320 and its surrounding components. The airflow temperature rises slightly but remains below the ambient temperature. Subsequently, the airflow is discharged from the air outlet 324 of the inflator 320 to the air inlet of the air pump 100, and re-enters the air pump 100 to participate in the next cycle. This design allows the gas, after initial cooling, to be reused, thus forming an airflow circulation path.

[0045] Since the temperature of the return gas is lower than that of ambient air, when it is re-inhaled into the air pump 100, the starting temperature of the air pump 100 during the compression process can be reduced compared to ambient temperature intake air, thus reducing compression power consumption and helping to enhance the cooling efficiency of the vortex tube 200.

[0046] In practical applications, the temperature of the gas discharged from the cold air outlet 220 of the vortex tube 200 is about 5℃~10℃. After the wireless charging device or seat heat dissipation is completed, the temperature of the gas discharged is about 10℃~15℃, but it is still lower than the ambient temperature. By connecting the air outlet 324 of the inflation plate 320 to the air inlet of the air pump 100, not only is the airflow recycling and reuse realized, but the overall operation of the cooling equipment is also more energy-efficient and efficient.

[0047] Please combine Figure 11 In some embodiments, the air pump 100 is provided with a mixing valve 110 at the air inlet end, the mixing valve 110 is provided with an air inlet pipe 111, and a return pipe 112 is provided between the mixing valve 110 and the air outlet 324.

[0048] It should be noted that the mixing valve 110 in this embodiment can achieve stable mixing of two gases. It has two gas inlets and one common outlet. One gas inlet is connected to the return pipe 112, and the other gas inlet is connected to the intake pipe 111. The other end of the intake pipe 111 is connected to the external environment.

[0049] The return pipe 112 guides the low-temperature gas discharged from the outlet 324 of the inflation plate 320 to the mixing valve 110, while the inlet pipe 111 is connected to the external environment to introduce outside air; the mixing valve 110, as a gas confluence device, enables the circulating gas from the return pipe 112 to be mixed with the external gas entering through the inlet pipe 111 before entering the air pump 100.

[0050] When the return flow is insufficient to meet the suction requirements of the air pump 100 due to gas loss during system operation, the mixing valve 110 can supplement some ambient gas to prevent the air pump 100's inlet pressure from continuously dropping. The mixing valve 110 achieves the function of maintaining the airflow balance at the air pump 100's inlet, ensuring that the air pump 100 can operate continuously under stable inlet conditions. It recycles low-temperature gas while supplementing with external gas, thus retaining the advantage of the residual cold energy of the return gas and preventing equipment malfunctions caused by excessive negative pressure.

[0051] In an optional embodiment, a vacuum switch 120 is also provided between the mixing valve 110 and the air inlet end of the air pump 100, and a one-way air inlet valve 1111 is provided on the air inlet pipe 111.

[0052] A vacuum switch 120 is installed between the mixing valve 110 and the inlet of the air pump 100 to monitor the vacuum level at the inlet of the air pump 100 in real time. When the vacuum level is detected to be too high, the vacuum switch 120 is triggered and outputs a control signal. The inlet pipe 111 is connected to the external environment. The one-way inlet valve 1111 on the inlet pipe 111 remains closed under normal operating conditions, but automatically opens after receiving the trigger signal from the vacuum switch 120, allowing outside air to flow into the mixing valve 110 through the inlet pipe 111. This design ensures that the external passage is only opened when the cooling equipment needs supplemental air, avoiding the adverse effects of continuously introducing high-temperature ambient air on the low-temperature characteristics of the return gas.

[0053] With the one-way inlet valve 1111 open, the outside gas and the low-temperature return gas mix in the mixing valve 110, forming a mixed airflow with a temperature between the two. This mixed airflow is then delivered to the inlet of the air pump 100, effectively alleviating negative pressure accumulation. The vacuum switch 120 and the one-way inlet valve 1111 work together to achieve precise control of the gas replenishment operation. Based on this, the cooling equipment can maintain efficient gas circulation while dynamically responding to changes in internal gas volume, ensuring that the inlet pressure of the air pump 100 is always within a safe operating range.

[0054] In other embodiments, such as Figure 12 As shown, the air outlet 324 of the inflation plate 320 can also be directly connected to the external environment through a pipeline. The air pump 100 absorbs gas from the ambient air to work. At this time, the mixing valve 110, the one-way air inlet valve 1111, and the vacuum switch 120 can be eliminated.

[0055] In some embodiments, the cooling equipment further includes an air storage tank 400 and a valve body 500, with the air outlet of the air pump 100, the air storage tank 400, the valve body 500, and the pipeline inlet 210 connected in sequence.

[0056] An air storage tank 400 and a valve body 500 are arranged between the outlet of the air pump 100 and the inlet 210 of the vortex tube 200. The compressed gas generated by the air pump 100 during operation is first delivered to the air storage tank 400, which can store a certain amount of high-pressure gas. The outlet of the air storage tank 400 is connected to the valve body 500, which can adjust the gas flow rate or on / off state as needed. Its response signal can come from the control system, enabling controllable gas supply. The valve body 500 is further connected to the inlet 210 of the vortex tube 200, thereby sending the pressure-stabilized and regulated compressed gas into the vortex tube 200.

[0057] The introduction of the gas storage tank 400 and the valve body 500 makes the gas transmission process from the gas pump 100 to the vortex tube 200 more stable and controllable, creating favorable conditions for the vortex tube 200 to efficiently generate low-temperature airflow. The gas is first pressurized by the gas pump 100, then stabilized and stored by the gas storage tank 400, and then released as needed through the valve body 500, finally entering the vortex tube 200 to participate in the hot and cold flow, forming an orderly and controllable gas transmission path.

[0058] In an optional embodiment, the receiving device 300 includes a wireless charging device and a seat, and the cooling equipment further includes a cooling pipe 600, which includes a main cooling pipe 610, a first cooling branch pipe 620, and a second cooling branch pipe 630. The main cooling pipe 610 is connected to the cooling outlet 220. The end of the main cooling pipe 610 away from the cooling outlet 220 is connected to both the first cooling branch pipe 620 and the second cooling branch pipe 630. The end of the first cooling branch pipe 620 away from the main cooling pipe 610 is connected to the wireless charging device, and the end of the second cooling branch pipe 630 away from the main cooling pipe 610 is connected to the seat. A solenoid valve 611 is provided on the main cooling pipe 610, and a pressure detection device 640 is provided on both the first cooling branch pipe 620 and the second cooling branch pipe 630.

[0059] In a scenario where the receiver 300 includes a wireless charging device and a seat, the low-temperature gas output from the cold air outlet 220 of the vortex tube 200 first enters the cold air main pipe 610. The cold air main pipe 610 guides the cold air to the first cold air branch pipe 620 and the second cold air branch pipe 630. The first cold air branch pipe 620 is used to supply cooling to the blown plate 320 in the wireless charging device, and the second cold air branch pipe 630 is used to supply cooling to the blown plate 320 in the seat. The gas discharged from the blown plate 320 flows back to the air pump 100 through two return pipes 112, or flows back to the air pump 100 after the two return pipes 112 converge.

[0060] A solenoid valve 611 is installed on the main air conditioning pipe 610 and is controlled to open or close via an electrical signal. When only cooling is needed for the wireless charging device or the seat, selective cooling can be achieved by adjusting the solenoid valve 611 through the control system. Air pressure detection devices 640 are respectively installed on the first air conditioning branch pipe 620 and the second air conditioning branch pipe 630 to monitor the gas pressure in each pipe in real time. If an abnormal pressure drop occurs in any branch pipe, a possible leak is detected, and an alarm signal is triggered.

[0061] In practical applications, when the user only uses the wireless charging function, the cooling equipment can activate the solenoid valve 611 and ensure that the first cooling branch pipe 620 is in a conductive state, while using the air pressure detection device 640 to monitor whether the internal air pressure of the first cooling branch pipe 620 is stable; when the user only uses the seat ventilation function, the cooling equipment can activate the solenoid valve 611 and ensure that the second cooling branch pipe 630 is in a conductive state, while using the air pressure detection device 640 to monitor whether the internal air pressure of the second cooling branch pipe 630 is stable; when the user uses both the wireless charging and seat ventilation functions, the cooling equipment can activate the solenoid valve 611 and simultaneously ensure that both the first cooling branch pipe 620 and the second cooling branch pipe 630 are in a conductive state, while using two air pressure detection devices 640 to monitor whether the internal air pressure of the first cooling branch pipe 620 and the second cooling branch pipe 630 is stable respectively.

[0062] When the receiving device 300 only includes a wireless charging device or a seat, a cooling pipe 600 can be provided between the cooling outlet 220 and the receiving device 300, for example. Figure 13 A schematic diagram of a cooling device is shown when the receiving device 300 includes only a wireless charging device.

[0063] In addition, please refer to Figure 14 Both the first air conditioning branch pipe 620 and the second air conditioning branch pipe 630 are fitted with wire harness protection devices 650.

[0064] It should be understood that in the vehicle's internal structure, the wireless charging device is generally located in the center console. The center console and the seat are usually movable parts. During the movement of the center console and the seat, the first air conditioning branch pipe 620 and the second air conditioning branch pipe 630 may twist or rub against other parts. Long-term operation may easily lead to pipe rupture.

[0065] By installing a wire harness protection device 650 on both the first air conditioning branch pipe 620 and the second air conditioning branch pipe 630, the wire harness protection device 650 effectively protects the air conditioning branch pipes, preventing them from cracking due to excessive bending or wear. The wire harness protection device 650 can be a hollow protective chain, with the first air conditioning branch pipe 620 and the second air conditioning branch pipe 630 respectively threaded through the corresponding protective chain.

[0066] In summary, the embodiments of this application provide a cooling device, which includes an air pump 100, a vortex tube 200, and a receiving device 300. When the air pump 100 is running, it compresses gas and delivers it to the pipeline inlet 210 of the vortex tube 200. After the compressed gas enters the interior of the vortex tube 200, it forms a high-temperature airflow and a low-temperature airflow. The high-temperature airflow flows to the hot gas outlet 230, and the low-temperature airflow flows to the cold gas outlet 220, thereby outputting low-temperature cold air to the receiving device 300. Compared with the method of the fan 330 blowing natural wind directly, the heat dissipation efficiency is improved.

[0067] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
