Description

Technical Field

[0001] The present invention generally relates to the technical field of vehicles, and more particularly to a thermal management device for vehicles. Background Art

[0002] Currently, many vehicles are equipped with wireless charging devices to provide wireless charging functions for electronic products such as mobile phones. The wireless charging device transfers energy through the principle of electromagnetic induction, and the energy loss during the energy transfer process will be dissipated in the form of heat. In particular, in high-power charging modes such as fast charging, the wireless charging device will significantly heat up. Once the temperature is too high, the charging efficiency will decrease or the mobile phone will overheat and be protected.

[0003] For this reason, the wireless charging devices on the market usually come with a heat dissipation module. Some wireless charging devices are equipped with Peltier chip components, which will lead to a relatively large cost increase.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] Figures 1 to 14B Shows a vehicle system 1 including a thermal management device 10 and its components according to the first exemplary embodiment of the present invention.

[0050] Reference Figures 1 to 7 and Figure 14A and Figure 14B Figure 14B , the vehicle system 1 can be arranged at the center console C between the driver's seat and the co-driver's seat of the vehicle V, for example, and can include a thermal management device 10 and a wireless charging device 20. The wireless charging device 20 can wirelessly charge electronic devices 30 such as mobile phones, tablets, and smart wearable devices. In this article, unless otherwise specified, electronic devices refer to electronic devices charged by the wireless charging device.

[0051] The thermal management device 10 can include a box body 100 and a thermal management unit 102. The box body 100 defines a storage cavity 104. The thermal management unit 102 includes a refrigeration circuit 106 for refrigerant flow. The thermal management unit 102 is configured to: cool the storage cavity 104 through the refrigeration circuit 106, and dissipate heat from the wireless charging device 20 of the vehicle through the refrigeration circuit 106 or the refrigerant cooled by the refrigeration circuit 106.

[0052] The above thermal management device 10 can provide the function of an in-vehicle refrigerator by cooling the storage cavity 104 through the refrigeration circuit 106, and at the same time can also dissipate heat from the wireless charging device 20 by using the refrigeration circuit 106 or the refrigerant cooled by the refrigeration circuit 106. Therefore, the thermal management device 10 integrates the heat dissipation module of the in-vehicle refrigerator and the wireless charging device 20, and there is no need to set up an independent heat dissipation module for the wireless charging device 20, which can reduce costs. And, compared with heat dissipation through a Peltier chip assembly, the above thermal management device 10 uses the refrigeration circuit 106 for refrigerant flow or the refrigerant cooled by the refrigeration circuit 106 to dissipate heat from the wireless charging device 20 and the electronic device 30 charged by the wireless charging device 20, and can obtain better heat dissipation and temperature reduction effects.

[0053] Reference Figures 2 to 7 and Figure 15 Figure 15 , the box body 100 and the refrigeration circuit 106 can form / make up an in-vehicle refrigerator.

[0054] In the illustrated embodiment, the box body 100 can include an inner liner 114 that defines the storage cavity 104, an outer shell 116 surrounding the inner liner 114, a heat insulation structure 118 provided between the outer shell 116 and the inner liner 114, and a box cover 120 for closing the storage cavity 104. The heat insulation structure 118 can be, for example, a heat insulation layer made of heat insulation material to provide a heat preservation function for the storage cavity 104.

[0055] In the illustrated embodiment, the refrigeration circuit 106 may include a compressor 108, a condenser 110, and an evaporator 112 that are fluidly connected to each other. The refrigeration circuit 106 may further include a throttle valve 122. The throttle valve 122 may be, for example but not limited to, a thermal expansion valve, an electronic expansion valve, etc. The compressor 108, the condenser 110, and the throttle valve 122 of the refrigeration circuit 106 may be disposed outside the cabinet 100. In the illustrated embodiment, the evaporator 112 is a blown evaporator and is formed as at least a part of the inner container 114. A blown evaporator is generally manufactured by the following method: two sheets are bonded together by rolling under high pressure, wherein certain portions of the sheets are grooved or treated with a release agent so that the sheets cannot be joined there, and these areas can be subsequently inflated with compressed air to form channels. Optionally, the evaporator 112 may be formed as the circumferential wall of the inner container 114, or the evaporator 112 may be formed as the circumferential wall and the bottom wall of the inner container 114 (in other words, the entire inner container 114 is formed by the evaporator 112). It is conceivable that in other embodiments, other suitable types of evaporators may also be used, such as a plate-type evaporator or a tube-in-tube evaporator disposed outside the inner container within the outer shell. The compressor 108, the condenser 110, the throttle valve 122, and the evaporator 112 of the refrigeration circuit 106 may be fluidly connected to each other. Specifically, the outlet of the compressor 108 may be in fluid communication with the inlet of the condenser 110, the outlet of the condenser 110 may be in fluid communication with the inlet of the throttle valve 122, the outlet of the throttle valve 122 may be in fluid communication with the inlet of the evaporator 112, and the outlet of the evaporator 112 may be in fluid communication with the inlet of the compressor 108 to effect a refrigeration cycle.

[0056] The thermal management unit 102 may further include a first sensor module 124 and a first control module 126 mainly for the vehicle-mounted refrigerator. The first sensor module 124 may include a first sensor 128 for detecting the temperature inside the storage cavity 104, and the first sensor 128 is a temperature sensor. The temperature inside the storage cavity 104 of the vehicle-mounted refrigerator may be controlled, for example, in the following manner: the real-time temperature inside the storage cavity 104 is detected by the first sensor 128; the sensed temperature signal is sent to the first control module 126; the first control module 126 determines whether the temperature inside the storage cavity 104 is higher than the set temperature: if it is higher than the set temperature, the compressor 108 is started to begin the circulation of the refrigerant; if it is equal to or lower than the set temperature, the compressor 108 is turned off to stop the circulation of the refrigerant.

[0057] Refer to Figure 2 、 Figure 14A 、 Figure 14B and Figure 15, in the illustrated embodiment, the wireless charging device 20 is disposed outside the housing 100 of the vehicle-mounted refrigerator and is spaced apart from the housing 100 by a certain distance. The wireless charging device 20 may include a charging platform 200, a charging coil 202, a second sensor module 204, and a second control module 206. The charging platform 200 may be used to place the electronic device 30 to be charged. The second sensor module 204 may be used to sense the placement state of the electronic device 30 to be charged and includes, but is not limited to, a proximity sensor, a load sensor, etc. The second control module 206 may receive the sensing data of the second sensor module 204 to determine the placement state of the electronic device 30 and control the charging coil 202 of the wireless charging device 20 to start the charging process when it is determined that the electronic device 30 is placed in place. In the illustrated embodiment, an interface 210 for connecting to the thermal management unit 102 may be provided at the edge of the charging platform 200. A notch 212 may be provided at a position of the charging platform 200 corresponding to the electronic device 30 such that there is a gap between the back of the electronic device 30 and the charging platform 200 when the electronic device 30 is placed in place on the charging platform 200. The refrigerant cooled by the refrigeration circuit 106 may be conveyed to the area where the wireless charging device 20 is located, for example, conveyed to the gap between the charging platform 200 and the electronic device 30 via the interface 210 to dissipate heat for the wireless charging device 20 and the electronic device 30.

[0058] Referring to Figure 2 , Figure 6 and Figure 7 , the thermal management unit 102 may include a first flow path 130 (which may also be referred to as a refrigerant flow path) and a first fluid driving device 132. The first flow path 130 is configured to allow the refrigerant to flow and is capable of conveying the refrigerant to the area where the wireless charging device 20 is located, and the first flow path 130 is at least partially disposed adjacent to the evaporator 112 to allow the refrigerant in the first flow path 130 to be cooled by heat exchange with the refrigerant in the evaporator 112. The first fluid driving device 132 is configured to drive the refrigerant to flow along the first flow path 130. The first fluid driving device 132 may be, for example, but not limited to, a fan, a fluid pump, etc. Optionally, the first control module 126 may control the start and stop of the first fluid driving device 132. In the case where the first fluid driving device 132 is a fan, the first control module 126 may also control the rotation speed of the first fluid driving device 132.

[0059] When the wireless charging device 20 charges the electronic device 30 or the temperature of the wireless charging device 20 and / or the electronic device 30 exceeds a threshold value, when the refrigeration circuit 106 is in an operating state, the thermal management unit 102 may execute a first heat dissipation mode to dissipate heat from the wireless charging device 20 and the electronic device 30. In the first heat dissipation mode, the refrigerant in the first flow path 130 can be cooled by exchanging heat with the refrigerant in the evaporator 112 and is conveyed to the area where the wireless charging device 20 is located, so as to dissipate heat from the wireless charging device 20 and the electronic device 30 through the cooled refrigerant.

[0060] It should be noted that in this article, the operating state of the refrigeration circuit 106 refers to the state in which the refrigeration circuit 106 operates to maintain the temperature in the storage chamber 104 at a set temperature. In other words, it refers to the state in which the refrigeration function / mode of the vehicle-mounted refrigerator is turned on. In the operating state of the refrigeration circuit 106, the compressor 108 of the refrigeration circuit 106 may operate intermittently. For example, when the temperature in the storage chamber 104 is equal to or lower than the set temperature, the compressor 108 will stop operating; when the temperature in the storage chamber 104 is higher than the set temperature, the compressor 108 will start. Correspondingly, in this article, the non-operating state of the refrigeration circuit 106 refers to the state in which the refrigeration circuit 106 does not operate. In other words, it refers to the state in which the refrigeration function / mode of the vehicle-mounted refrigerator is turned off. In the non-operating state of the refrigeration circuit 106, the compressor 108 of the refrigeration circuit 106 never operates.

[0061] In the illustrated embodiment, the refrigerant in the first flow path 130 is air. Among them, the first flow path 130 is configured to be able to receive external air and convey the air cooled by exchanging heat with the evaporator 112 to the area where the wireless charging device 20 is located. It can be envisioned that in some other embodiments not shown, the refrigerant may be other suitable cooling fluids, such as cooling gases or cooling liquids. Commonly used refrigerants include but are not limited to carbon dioxide, isobutane, propane, water, etc. When the refrigerant is not air, the first flow path can be designed as a flow loop so that the refrigerant can circulate in the first flow path to perform a heat dissipation cycle. In each heat dissipation cycle, the refrigerant can first exchange heat with the refrigerant in the evaporator to be cooled, then exchange heat with the wireless charging device and the electronic device to increase in temperature, and then perform the next heat dissipation cycle.

[0062] Refer to Figures 4 to 6 and Figure 15, the thermal management unit 102 may include a second flow path 134 (which may also be referred to as a circulation flow path) and a second fluid driving device 136. Both the inlet and the outlet of the second flow path 134 communicate with the storage cavity 104. The second fluid driving device 136 is configured to be able to drive the air in the storage cavity 104 into the second flow path 134, and flow along the second flow path 134 and return to the storage cavity 104. The second flow path 134 and the first flow path 130 are independent of each other. The first flow path 130 is at least partially disposed adjacent to the second flow path 134 to allow the refrigerant in the first flow path 130 to be cooled by exchanging heat with the air in the second flow path 134.

[0063] Through the cooperation of the second flow path 134 and the second fluid driving device 136, it is possible to promote the circulation of the air cooled by the refrigeration circuit 106 in the storage cavity 104 in the working state of the refrigeration circuit 106, making the temperatures of all regions of the storage cavity 104 more consistent, thereby improving the refrigeration effect. The second fluid driving device 136 may be, for example but not limited to, a fan, a fluid pump, etc. The second fluid driving device 136 may be started, for example, when the refrigeration circuit 106 enters the working state (i.e., the vehicle-mounted refrigerator starts the refrigeration function), and may be turned off when the refrigeration circuit 106 enters the non-working state (i.e., the vehicle-mounted refrigerator turns off the refrigeration function). Optionally, the first control module 126 may control the start and stop of the second fluid driving device 136.

[0064] By disposing the first flow path 130 at least partially adjacent to the second flow path 134, in the first heat dissipation mode, the refrigerant in the first flow path 130 can be cooled by exchanging heat with the cooled air in the second flow path 134 in addition to exchanging heat with the refrigerant in the evaporator 112, thereby enhancing the cooling effect on the refrigerant in the first flow path 130, and further improving the heat dissipation effect of the refrigerant in the first flow path 130 on the wireless charging device 20 and the electronic device 30 in the first heat dissipation mode.

[0065] Refer to Figure 2 、 Figure 6 、 Figure 7 And Figures 11A to 12B , the thermal management unit 102 may further include a third flow path 138 (which may also be referred to as an air-cooled flow path or a normal-temperature flow path). The third flow path 138 is configured to be able to receive outside air and deliver the air to the area where the wireless charging device 20 is located. The third flow path 138 may be farther from the evaporator 112 than the first flow path 130. In the illustrated embodiment, the first flow path 130 and the third flow path 138 may have a common part, and the second flow path 134 and the third flow path 138 are independent of each other, which will be more easily understood in combination with the following description. It can be envisioned that in some other embodiments not shown, the first flow path 130 may be independent of the third flow path 138 without a common part.

[0066] When the wireless charging device 20 charges the electronic device 30 or the temperature of the wireless charging device 20 and / or the electronic device 30 exceeds a threshold value, when the refrigeration circuit 106 is in a non-operating state, the thermal management unit 102 may execute a second heat dissipation mode to dissipate heat from the wireless charging device 20 and the electronic device 30. In the second heat dissipation mode, an air flow may be blown to the wireless charging device 20 and the electronic device 30 through the third flow path 138 to perform air-cooled heat dissipation on the wireless charging device 20 and the electronic device 30. Among them, the third flow path 138 is arranged to be farther away from the evaporator 112 than the first flow path 130, which can reduce or prevent the refrigerant in the evaporator 112 from exchanging heat with the room-temperature air or the air slightly lower than the room temperature in the third flow path 138 and rising in temperature.

[0067] In the illustrated embodiment, both the first flow path 130 and the third flow path 138 can receive outside air and allow air to flow, so the first fluid driving device 132 can be shared to provide the driving force for the air in the first flow path 130 and the third flow path 138. In other words, the first fluid driving device 132 is configured to be able to drive the outside air into the first flow path 130 and flow along the first flow path 130, and be able to drive the outside air into the third flow path 138 and flow along the third flow path 138. It can be envisioned that in some other embodiments not shown, two fluid driving devices may be provided to respectively provide the driving force for the refrigerant in the first flow path and the air in the third flow path.

[0068] The thermal management unit 102 may further include one or more valves to control the flow and interruption of the first flow path 130 and / or the third flow path 138. In the illustrated embodiment, valves 140A and 140B for controlling the on / off of the first flow path 130 are provided, and the third flow path 138 has an open inlet and outlet and is not equipped with corresponding valves to always maintain flow. In the first heat dissipation mode when the refrigeration circuit 106 is in an operating state, both the first flow path 130 and the third flow path 138 may have flow to dissipate heat from the wireless charging device 20 and the electronic device 30 simultaneously through the refrigerant in the first flow path 130 and the air flow in the third flow path 138. In the second heat dissipation mode when the refrigeration circuit 106 is in a non-operating state, the first flow path 130 may be interrupted and the third flow path 138 may have flow to dissipate heat from the wireless charging device 20 and the electronic device 30 using only the air flow in the third flow path 138. The heat dissipation effect of the first heat dissipation mode is better than that of the second heat dissipation mode. The thermal management unit 102 may selectively switch between the first heat dissipation mode and the second heat dissipation mode based on whether the refrigeration circuit 106 is in an operating state and / or the heat dissipation requirements of the wireless charging device 20 and the electronic device 30.

[0069] It is conceivable that in some other embodiments not shown, valves for controlling the on / off of the first flow path and valves for controlling the on / off of the third flow path may be provided separately to allow: in the first heat dissipation mode when the refrigeration circuit is in the working state, the first flow path can conduct fluid and the third flow path can be cut off, so as to separately use the refrigerant in the first flow path to dissipate heat from the wireless charging device and the electronic device.

[0070] Continue to refer to Figure 2 、 Figures 4 to 7 and Figures 11A to 14B In the illustrated embodiment, the heat management unit 102 may include a flow channel member 142 and a flow guiding member 144. The flow channel member 142 is disposed outside the inner container 114 and adjacent to the circumferential wall of the inner container 114 (i.e., adjacent to the evaporator 112). In the illustrated embodiment, most of the flow channel member 142 is disposed between the inner container 114 and the outer shell 116. In the illustrated embodiment, the flow guiding member 144 is located outside the outer shell 116.

[0071] In the illustrated embodiment, the flow channel member 142 and the circumferential wall of the inner container 114 (i.e., the evaporator 112) jointly define a first channel 146, such that the first channel 146 is adjacent / close to the evaporator 112. It is conceivable that in some other embodiments not shown, in the case where the evaporator is disposed outside the inner container (for example, the evaporator is a tube-in-tube evaporator), the flow channel member may be disposed adjacent / close to the evaporator, and the flow channel member itself may define a first channel adjacent / close to the evaporator inside it. In the illustrated embodiment, the first channel 146 is disposed between the inner container 114 and the outer shell 116 and is surrounded by the heat insulation structure 118. In the illustrated embodiment, the flow guiding member 144 defines a second channel 148, and the second channel 148 is located outside the outer shell 116. The inlet of the first channel 146 can receive external air, the outlet of the first channel 146 is communicated with the inlet of the second channel 148, and the outlet of the second channel 148 is adjacent to the wireless charging device 20. In the illustrated embodiment, the outlet of the second channel 148 may be connected to the interface 210 of the wireless charging device 20 to blow air flow into the gap between the charging platform 200 and the electronic device 30. The first channel 146 and the second channel 148 are coupled / connected in series to form a first flow path 130 ( Figure 6 and Figure 9The arrow indicates the flow direction of the refrigerant in the first flow path 130), allowing outside air to enter the first flow path 130 and be conveyed / blown to the wireless charging device 20 and the electronic device 30 via the first flow path 130. In the illustrated embodiment, the wireless charging device 20 can charge two electronic devices 30 simultaneously (i.e., has two charging positions). Correspondingly, the second channel 148 has two outlets to respectively convey / blow airflows to the two electronic devices 30 for heat dissipation. It is conceivable that in some other embodiments not shown, the second channel may also have other suitable numbers of outlets.

[0072] In the illustrated embodiment, the flow channel member 142 itself defines the second flow path 134 ( Figure 4 The arrow indicates the flow direction of the airflow in the second flow path 134). The first channel 146 is located between the evaporator 112 and the second flow path 134 and is adjacent / close to the evaporator 112 and the second flow path 134, such that: in the first heat dissipation mode when the refrigeration circuit 106 is in operation, the refrigerant in the first channel 146 can exchange heat with the refrigerant in the evaporator 112 and the cooled air in the second flow path 134 and be cooled. In the illustrated embodiment, both the first channel 146 and the second flow path 134 are in the form of generally flat chambers to increase the heat exchange area between the refrigerant in the first channel 146, the refrigerant in the evaporator 112, and the cooled air in the second flow path 134, and improve the cooling effect on the refrigerant in the first channel 146. In the illustrated embodiment, the second flow path 134 is provided between the inner liner 114 and the outer shell 116 and is surrounded by the heat insulation structure 118.

[0073] In the illustrated embodiment, the flow channel member 142 itself also defines the third channel 150. The third channel 150 can be arranged to be farther from the evaporator 112 than the first channel 146. The inlet of the third channel 150 can receive outside air, and the outlet of the third channel 150 is in communication with the inlet of the second channel 148. The third channel 150 and the second channel 148 are connected / connected in series to form the third flow path 138 ( Figure 7 The arrow indicates the flow direction of the airflow in the third flow path 138), allowing outside air to enter the third flow path 138 and be conveyed / blown to the wireless charging device 20 and the electronic device 30 via the third flow path 138.

[0074] In the illustrated embodiment, the third channel 150 is also disposed between the inner container 114 and the outer shell 116, and the third channel 150 is spaced apart from the first channel 146 and the second flow path 134 to reduce or prevent, for example, the refrigerant in the first channel 146 and the air in the second flow path 134 from being heated up due to heat exchange with the room temperature air or near room temperature air in the third channel 150 in the first heat dissipation mode and the second heat dissipation mode. In the illustrated embodiment, the second flow path 134 is located between the first channel 146 and the third channel 150, and the third channel 150 is spaced apart from the first channel 146 and the second flow path 134 by a heat insulation structure 118.

[0075] In the illustrated embodiment, the flow channel member 142 further includes an inlet port 152 and an outlet port 153. External air can flow into the first channel 146 and the third channel 150 via the inlet port 152, and the air flowing out of the first channel 146 and the third channel 150 can enter the second channel 148 via the outlet port 153. In other words, the first channel 146 and the third channel 150 are in parallel and in series with the second channel 148. In the illustrated embodiment, both the inlet port 152 and the outlet port 153 are disposed at the outer shell 116 of the cabinet 100 and extend through the outer shell 116.

[0076] In the illustrated embodiment, the first flow path 130, the second flow path 134, and the third flow path 138 are defined by the flow channel member 142 and the diversion member 144. However, in some other embodiments not shown, the first flow path, the second flow path, and the third flow path may also be defined by components having other suitable configurations.

[0077] In the illustrated embodiment, the first fluid driving device 132 is disposed at the inlet port 152 outside the outer shell 116 and is adapted to blow air into the first channel 146 and the third channel 150. In the illustrated embodiment, a first valve 140A and a second valve 140B are respectively disposed at the inlet and outlet of the first channel 146 to control the flow through and cut-off of the first channel 146, and thus control the flow through and cut-off of the first flow path 130. No valve 140 is provided at the third channel 150, so that the third flow path 138 always remains flowing.

[0078] In the illustrated embodiment, the first valve 140A and the second valve 140B can be opened when the pressure of the air flow caused by the first fluid driving device 132 is greater than or equal to a predetermined value. The first valve 140A and the second valve 140B have similar structures and working principles. Hereinafter, the first valve 140A will be taken as an example for introduction. In the illustrated embodiment, the first valve 140A may include a valve body 154, a valve core 156, a valve seat 158, and a spring 160. The valve core 156 is installed on the valve body 154 and can be relative to the valve body 154 in Figure 11A the shown closed position andFigure 11B move between the illustrated open positions. A spring 160 is disposed between the valve body 154 and the valve core 156 and is adapted to bias the valve core 156 toward the closed position. When the valve core 156 is in the closed position, the opening 162 on the valve seat 158 is closed, so that the air flow cannot enter the first channel 146 through the first valve 140A and further cannot enter the first flow path 130; when the valve core 156 is in the open position, the opening 162 on the valve seat 158 is opened to allow the air flow to enter the first channel 146 through the first valve 140A( Figure 11B The arrows in show the flow direction of the air flow), and then enter the first flow path 130.

[0079] In the illustrated embodiment, the first fluid driving device 132 is a fan and can blow air toward the first valve 140A. When the pressure of the air flow is greater than or equal to a predetermined value, the thrust applied by the air flow to the valve core 156 is greater than the force applied by the spring 160 to the valve core 156, so that the valve core 156 can overcome the elastic force of the spring 160 and move from the closed position toward the open position, thereby opening the first valve 140A. By adjusting the rotational speed of the first fluid driving device 132, the pressure of the air flow can be adjusted, and thus the opening and closing of the first valve 140A can be controlled. Similarly, the second valve 140B can be opened when the pressure of the air flow in the first channel 146 is greater than or equal to a predetermined value to allow the air flow in the first channel 146 to flow into the second channel 148 through the second valve 140B( Figure 12B The arrows in show the flow direction of the air flow). When the first fluid driving device 132 is closed, both the first valve 140A and the second valve 140B are closed to maintain the seal of the first channel 146, preventing the ambient room temperature air from entering the first channel 146 to exchange heat with the cooler in the evaporator 112, thereby reducing the refrigeration capacity of the evaporator 112 for the storage cavity 104.

[0080] It is conceivable that in some other embodiments not shown, a valve can also be provided at the third channel to control the flow-through and cut-off of the third channel, and thus control the flow-through and cut-off of the third flow path; in some other embodiments not shown, other mechanically or electrically controlled valves with suitable structures can also be used to control the flow-through and cut-off of the first flow path and / or the third flow path. When the valve for controlling the flow-through and cut-off of the first flow path and / or the third flow path is an electrically controlled valve, the first control module can also control the opening and closing of the electrically controlled valve.

[0081] Referring to Figure 15, an electronic control unit 40 of the vehicle (i.e., vehicle ECU) can communicate with the first control module 126 and the second control module 206. The electronic control unit 40 can determine whether the charging coil 202 of the wireless charging device 20 starts a charging process according to a signal from the second control module 206. When it is determined that the charging coil 202 of the wireless charging device 20 has started the charging process, the electronic control unit 40 can determine whether the refrigeration circuit 106 is in a working state or a non-working state according to a signal from the first control module 126.

[0082] When the electronic control unit 40 determines that the refrigeration circuit 106 is in a working state, it can send a signal to the first control module 126 to make the first control module 126 control the thermal management unit 102 to execute the first heat dissipation mode. Specifically, for the illustrated embodiment, this can include controlling, by the first control module 126, the first fluid driving device 132 to open and adjust the rotation speed of the first fluid driving device 132 such that both the first valve 140A and the second valve 140B are opened; and when the valves for controlling the on-off flow of the first flow path 130 and / or the third flow path 138 are electrically controlled valves, this can further include controlling the opening and closing of the electrically controlled valves such that the first flow path 130 has a flow and the third flow path 138 has no flow, or the first flow path 130 has a flow and the third flow path 138 has a flow.

[0083] When the electronic control unit 40 determines that the refrigeration circuit 106 is in a non-working state, it can send a signal to the first control module 126 to make the first control module 126 control the thermal management unit 102 to execute the second heat dissipation mode. Specifically, for the illustrated embodiment, this can include controlling, by the first control module 126, the first fluid driving device 132 to open and adjust the rotation speed of the first fluid driving device 132 such that both the first valve 140A and the second valve 140B are closed; and when the valves for controlling the on-off flow of the first flow path 130 and / or the third flow path 138 are electrically controlled valves, this can further include controlling the opening and closing of the electrically controlled valves such that the first flow path 130 has no flow and the third flow path 138 has a flow.

[0084] Referring to Figure 13 , the thermal management device 10 may further include a heating element 164, and the heating element 164 can heat the storage cavity 104 and / or defrost the first valve 140A and the second valve 140B. In the illustrated embodiment, the heating element 164 is in the form of a heating pad and is disposed around the inner container 114, and more specifically, is disposed in contact with the outer surface of the inner container 114.

[0085] The first control module 126 can control the heating element 164 to heat, so as to switch the vehicle-mounted refrigerator to the heating mode. When the heating element 164 is heating, the refrigeration circuit 106 is in a non-operating state. At this time, the thermal management unit 102 can execute the above-mentioned second heat dissipation mode to blow air flow through the third flow path 138 to the wireless charging device 20 and the electronic device 30 for heat dissipation. In the illustrated embodiment, the third channel 150 of the third flow path 138 is spaced apart from the heating element 164 by the heat insulation structure 118, so as to reduce or avoid the adverse thermal effect of the heating element 164 on the air in the third flow path 138 when the heating element 164 is heating.

[0086] The first sensor module 124 may further include a second sensor 166 for detecting whether the first valve 140A and the second valve 140B are frosted. The second sensor 166 is, for example, a pressure sensor or a temperature sensor disposed in the first channel 146. The first control module 126 can receive the data sensed by the second sensor 166 to judge whether the first valve 140A and the second valve 140B are frosted, and can control the heating element 164 to heat after determining that the first valve 140A and / or the second valve 140B is frosted, so as to defrost the valve.

[0087] Figures 16A to 16B A vehicle system 1 according to a second exemplary embodiment of the present invention and its components are shown.

[0088] The vehicle system 1 according to the second exemplary embodiment of the present invention also includes a thermal management device 10 and a wireless charging device 20. The difference between the vehicle system according to the second exemplary embodiment and the vehicle system according to the first exemplary embodiment is that the structure of the evaporator 112 of the thermal management unit 102 of the thermal management device 10 of the vehicle system 1 according to the second exemplary embodiment is different from that of the first exemplary embodiment, and the thermal management unit 102 of the thermal management device 10 of the vehicle system 1 according to the second exemplary embodiment directly cools the wireless charging device 20 and the electronic device 30 charged by the wireless charging device 20 through the evaporator 112. This is particularly advantageous for application scenarios where the housing 100 of the thermal management device 10 and the wireless charging device 20 are relatively close, and can simplify the structure of the thermal management device 10.

[0089] Refer to Figure 16A and Figure 16B , the thermal management device 10 of the vehicle system 1 according to the second exemplary embodiment of the present invention includes a housing 100 and a thermal management unit 102. The housing 100 defines a storage cavity. In Figure 16AOnly the inner container 114 and the lid 120 of the box body 100 are shown. The box body 100 may further include an outer shell and a heat insulation structure disposed between the outer shell and the inner container. The thermal management unit 102 includes a refrigeration circuit 106. The refrigeration circuit 106 includes a compressor 108, a condenser 110, a throttle valve 122, and an evaporator 112 that are fluidly connected to each other to form a refrigerant circulation circuit. At least a portion of the evaporator 112 is disposed adjacent to the wireless charging device 20 of the vehicle. The thermal management unit 102 is configured to dissipate heat from the wireless charging device 20 through the aforementioned at least a portion of the evaporator 112. In the illustrated embodiment, the evaporator 112 includes a first portion 168 and a second portion 170 that communicate with each other. The evaporation tubes of the first portion 168 and the second portion 170 communicate with each other and both receive refrigerant from the throttle valve 122. The first portion 168 is integrated into the box body 100 to form at least a portion of the inner container 114 of the box body 100 that defines a storage cavity, and the first portion 168 is used to cool the storage cavity. The second portion 170 is disposed adjacent to the wireless charging device 20 of the vehicle to allow the refrigerant in the second portion 170 to exchange heat with the wireless charging device 20, thereby dissipating heat from the wireless charging device 20. The second portion 170 may be directly attached to the wireless charging device 20 (e.g., attached to the charging coil 202 of the wireless charging device 20) to directly dissipate heat from the wireless charging device 20 and indirectly dissipate heat from the electronic device 30 charged by the wireless charging device 20.

[0090] Figure 17 FIG. 4 shows a vehicle system 1 and its components according to a third exemplary embodiment of the present invention.

[0091] The vehicle system 1 according to the third exemplary embodiment of the present invention includes a thermal management device 10 and a wireless charging device 20. The difference between the vehicle system according to the third exemplary embodiment and the vehicle system according to the first exemplary embodiment is that the thermal management unit 102 of the thermal management device 10 of the vehicle system 1 according to the third exemplary embodiment includes a first evaporator 112A and a second evaporator 112B that are connected in parallel with each other. The first evaporator 112A and the second evaporator 112B receive refrigerant from the same condenser 110. The thermal management unit 102 is configured to: cool the storage cavity through the first evaporator 112A, and dissipate heat from the wireless charging device 20 of the vehicle through the refrigerant cooled by the second evaporator 112B.

[0092] Referring to Figure 17 FIG. 2, the thermal management device 10 of the vehicle system 1 according to the second exemplary embodiment of the present invention includes a box body 100 and a thermal management unit 102. The box body 100 defines a storage cavity. In Figure 17Only the inner container 114 and the lid 120 of the box body 100 are shown. The box body 100 may further include an outer shell and a heat insulation structure disposed between the outer shell and the inner container.

[0093] The thermal management unit 102 includes a refrigeration circuit 106. The refrigeration circuit 106 may include a compressor 108, a condenser 110, a first throttle valve 122A, a second throttle valve 122B, a first evaporator 112A, and a second evaporator 112B that are fluidly connected to each other. Specifically, the outlet of the compressor 108 may be in fluid communication with the inlet of the condenser 110, the outlet of the condenser 110 may be in fluid communication with the inlets of the first throttle valve 122A and the second throttle valve 122B, the outlet of the first throttle valve 122A may be in fluid communication with the inlet of the first evaporator 112A, the outlet of the second throttle valve 122B may be in fluid communication with the inlet of the second evaporator 112B, and the outlets of the first evaporator 112A and the second evaporator 112B may be in fluid communication with the inlet of the compressor 108 to achieve the circulation of the refrigerant.

[0094] By providing the first throttle valve 122A and the second throttle valve 122B respectively for the first evaporator 112A and the second evaporator 112B, the first evaporator 112A and the second evaporator 112B can be allowed to operate independently, thereby allowing independent refrigeration of the storage cavity 104 and heat dissipation of the wireless charging device 20. Thus, when the refrigeration function of the in-vehicle refrigerator is turned off (no refrigeration of the storage cavity), the second evaporator 112B of the refrigeration circuit 106 can be used to dissipate heat from the wireless charging device 20 and the electronic device 30. It can be envisaged that in some other embodiments not shown, the refrigerant from the condenser may also flow through the same throttle valve and then flow into the first evaporator and the second evaporator respectively. The first throttle valve 122A and the second throttle valve 122B may be electronic expansion valves.

[0095] In the illustrated embodiment, the thermal management unit 102 includes a refrigerant flow channel 172 and a refrigerant driving device 174, whose structure and function are similar to those of the first flow path 130 and the first fluid driving device 132 in the first exemplary embodiment. The refrigerant flow channel 172 is configured to allow the refrigerant to flow and is capable of delivering the refrigerant to the area where the wireless charging device 20 is located. The refrigerant flow channel 172 is at least partially disposed adjacent to the second evaporator 112B to allow the refrigerant in the refrigerant flow channel 172 to be cooled by heat exchange with the refrigerant in the second evaporator 112B. The refrigerant driving device 174 is configured to drive the refrigerant to flow along the refrigerant flow channel 172, and the refrigerant driving device 174 may be, for example, but not limited to, a fan or a fluid pump.

[0096] In the illustrated embodiment, the refrigerant flow path 172 may include a first refrigerant passage 176 disposed adjacent to the second evaporator 112B and a second refrigerant passage 178 coupled / connected in series with the first refrigerant passage 176. The first refrigerant passage 176 may be generally in the form of a flat chamber to increase the heat exchange area between the refrigerant in the first refrigerant passage 176 and the refrigerant in the second evaporator 112B.

[0097] In the illustrated embodiment, the refrigerant may be air. Accordingly, the refrigerant driving device 174 may be a fan and disposed at the inlet of the first refrigerant passage 176 to blow air into the first refrigerant passage 176. The air in the first refrigerant passage 176 may exchange heat with the refrigerant in the second evaporator 112B and be blown through the second refrigerant passage 178 to the area where the wireless charging device 20 is located, for example, blown into the gap between the wireless charging device 20 and the electronic device being charged by it, to dissipate heat for the wireless charging device 20 and the electronic device.

[0098] It is conceivable that in some other embodiments not shown, the refrigerant flow path and the refrigerant driving device may not be provided, but instead, the wireless charging device may be directly cooled and the electronic device may be indirectly cooled through the second evaporator, similar to the second part 170 of the evaporator 112 in the second embodiment.
