[0016] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this disclosure can be combined with each other. This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] Currently, oxygen generators are often integrated into vehicles to improve air quality inside.

[0023] In oxygen concentrators, air compressors are commonly used to compress air, which is then passed to devices such as molecular sieves to produce oxygen. To prevent the air compressor from overheating, air cooling is often used to dissipate heat from the compressor.

[0024] However, when the external ambient temperature of the vehicle is high, the heat dissipation effect of air cooling is relatively limited, which may lead to excessively high air compressor temperature and consequently reduce the service life of the air compressor.

[0025] This disclosure provides a cooling system for a vehicle, comprising a cooling jacket 1, a detection component, and a controller. Figure 1 , Figure 2 As shown, a cooling jacket 1 is used to wrap around the outside of the air compressor 2. The cooling jacket 1 has a liquid channel for thermal coupling with the air compressor 2. The liquid channel has a first connected state connecting to the vehicle's first cooling circuit and a second connected state connecting to the vehicle's second cooling circuit. The liquid channel has an inlet 11 and an outlet 12. A detection component is used to acquire status data, including the housing temperature of the air compressor 2. A controller is electrically connected to the detection component and is used to control the connection state of the liquid channel based on the status data and the pre-stored correspondence between the status data and the connection state.

[0026] By using the cooling system provided in this embodiment, the air compressor 2 can be liquid-cooled by connecting the cooling jacket 1 to the cooling circuit inside the vehicle. Compared with air cooling, this improves the heat dissipation effect of the air compressor 2, thereby reducing the possibility of the air compressor 2 overheating and thus improving the service life of the air compressor 2.

[0027] The "pre-stored correspondence between state data and connectivity states" can be manually adjusted data or fixed data, which can be stored in memory in the form of, for example, but not limited to, fitted curves or forms.

[0028] Optionally, the detection component includes a first temperature sensor located at the housing of the air compressor 2 to detect the housing temperature of the air compressor 2.

[0029] like Figure 2 As shown, the air compressor 2 has multiple cylinders, which are the main heat source of the air compressor 2. The liquid passage can be spiral-shaped and wrapped around the outside of the multiple cylinders, thereby effectively reducing the temperature of the air compressor 2.

[0030] like Figure 1 As shown, the cooling jacket 1 includes a first housing 1a and a second housing 1b, which are detachably connected.

[0031] Thus, by molding the cooling jacket 1 in separate parts, the molding efficiency of the cooling jacket 1 can be improved. Furthermore, since the first housing 1a and the second housing 1b are detachable, the cooling jacket 1 can be disassembled in a timely manner when the air compressor 2 malfunctions, thereby facilitating the maintenance of the air compressor 2.

[0032] Optionally, the first housing 1a and the second housing 1b can be cast from a metal material. This improves the high-temperature resistance of the cooling jacket 1, thereby extending its service life. Furthermore, the metal material has high thermal conductivity, which improves the heat transfer efficiency between the coolant in the cooling channel and the air compressor 2.

[0033] The oxygen-generating component of a car-mounted oxygen concentrator includes at least two molecular sieve canisters. Taking two molecular sieve canisters as an example, each canister can absorb nitrogen from compressed air, allowing oxygen to flow out and thus generating oxygen. When the air pressure (mainly nitrogen) in one molecular sieve canister becomes too high, the air in that canister needs to be extracted. During this extraction process, the system switches to the other molecular sieve canister to continue generating oxygen. In this way, the alternating operation of the two molecular sieve canisters ensures continuous oxygen production.

[0034] like Figure 1 As shown, the cooling jacket 1 also has an air inlet 13, an air outlet, a vacuum inlet 14, and a vacuum exhaust outlet 15. The air inlet 13 is connected to the air inlet of the air compressor 2, and the air outlet is connected to the air outlet of the air compressor 2. The vacuum inlet 14 and the vacuum exhaust outlet are connected to the inlet and outlet of the molecular sieve tank, respectively, and both are open to the outside atmosphere.

[0035] Thus, through the aforementioned cooling jacket 1, compressed air can be supplied to the molecular sieve tank by the air compressor 2, and the air inside the molecular sieve tank can be expelled, thereby achieving the continuous oxygen production effect of the oxygen generator.

[0036] like Figure 1 As shown, a shock absorber 17 is provided at the bottom of the cooling jacket 1. During the operation of the air compressor 2 or in the vehicle, the air compressor 2 will generate large vibrations. By providing a shock absorber 17 at the bottom of the cooling jacket 1, the air compressor 2 can be buffered, thereby reducing the vibration of the air compressor 2 and improving the stability of the air compressor 2 during operation.

[0037] Combination Figure 1 , Figure 2 As shown, the cooling jacket 1 has a drive plate 21 inside, which is used to drive the air compressor 2 to work. The cooling jacket 1 also has a power interface 16 and a communication interface 18, which are electrically connected to the drive plate 21 respectively.

[0038] In this way, the air compressor 2 can be powered by the power interface 16 and controlled by the communication interface 18.

[0039] In some embodiments, the cooling jacket 1 has an internal cavity in which the air compressor 2 is located. The cavity is filled with a cooling medium, which can be, for example, but not limited to, an ethylene glycol solution. The cooling medium is located between the inner wall of the cooling jacket 1 and the air compressor 2; that is, the air compressor 2 is immersed in the cooling medium. During operation, the air compressor 2 first transfers heat to the cooling medium, then the cooling medium transfers heat to the housing of the cooling jacket, and finally the housing of the cooling jacket transfers heat to the liquid in the liquid channel.

[0040] In some embodiments, the cooling system further includes a flow valve located at the inlet 11. The status data also includes the opening degree of the flow valve. A controller is electrically connected to the flow valve and is further configured to: control the opening degree of the flow valve based on the status data and a pre-stored correspondence between the status data and the flow valve opening degree.

[0041] By adjusting the opening of the flow valve, the cooling effect of the coolant in the liquid channel on the air compressor 2 can be adjusted, thereby enabling the air compressor 2 to operate within a stable temperature range.

[0042] Optionally, the status data also includes the flow rate at inlet 11, and the opening degree of the flow valve can be determined based on the flow rate at inlet 11.

[0043] Optionally, the detection component also includes a flow meter located at the inlet 11 for detecting the flow rate at the inlet 11.

[0044] In some embodiments, controlling the opening of the flow valve includes: increasing the opening of the flow valve when the housing temperature of the air compressor 2 meets a specified high temperature condition and the opening of the flow valve has not reached its maximum opening.

[0045] In this way, when the casing temperature of the air compressor 2 is too high, the opening of the flow valve can be increased, thereby increasing the flow rate of coolant in the cooling channel, improving the cooling effect of the cooling channel on the air compressor 2, and thus reducing the casing temperature of the air compressor 2 to a level that does not meet the specified high temperature conditions.

[0046] Optionally, the specified high temperature condition is that the casing temperature of the air compressor 2 is higher than the first specified temperature. Of course, the specified high temperature condition can also be that the casing temperature of the air compressor 2 is higher than or equal to the first specified temperature. This disclosure does not limit this aspect.

[0047] The first specified temperature can be a preset temperature or a temperature that the user can adjust himself / herself; this embodiment of the present disclosure does not limit this.

[0048] This ensures that the heat from all parts of the air compressor 2 can be stably transferred to the liquid in the liquid channel, thereby ensuring the heat dissipation efficiency of the air compressor 2.

[0049] In some embodiments, the cooling system further includes a first three-way valve and a second three-way valve, which are electrically connected to the controller. The three ports of the first three-way valve are respectively connected to the liquid inlet 11, the first cooling circuit, and the second cooling circuit. The port of the first three-way valve connected to the liquid inlet 11 is selectively connected to one of the ports of the first three-way valve connected to the first cooling circuit and the second cooling circuit. The three ports of the second three-way valve are respectively connected to the liquid outlet 12, the first cooling circuit, and the second cooling circuit. The port of the second three-way valve connected to the liquid outlet 12 is selectively connected to one of the ports of the second three-way valve connected to the first cooling circuit and the second cooling circuit.

[0050] In this way, the controller can control the first three-way valve and the second three-way valve to connect the cooling channel to the first cooling circuit or the cooling channel to the second cooling circuit.

[0051] In some embodiments, controlling the opening of the flow valve further includes: reducing the opening of the flow valve when the housing temperature of the air compressor 2 does not meet the specified high temperature condition and the opening of the flow valve reaches the maximum opening.

[0052] Since the cooling circuit inside the vehicle also needs to cool other parts of the vehicle, when the housing temperature of the air compressor 2 does not meet the specified high temperature conditions and the opening degree of the flow valve reaches the maximum opening degree, the flow rate of other parts can be increased by reducing the opening degree of the flow valve. This can improve the cooling effect of the cooling circuit on other parts of the vehicle while ensuring that the housing temperature of the air compressor 2 is within a stable range.

[0053] In some embodiments, the temperature of the coolant in the first cooling circuit is higher than the temperature of the coolant in the second cooling circuit. For example, the first cooling circuit can dissipate heat by air cooling, while the second cooling circuit is integrated into the air conditioning system, and the liquid flowing through the second cooling circuit to the liquid inlet 11 is a cooled refrigerant.

[0054] The control of the connection status of the liquid passage includes: when the liquid passage is connected to the first cooling circuit, the casing temperature of the air compressor 2 meets the specified high temperature condition, and the opening degree of the flow valve reaches the maximum opening degree, the control of the liquid passage to be connected to the second cooling circuit.

[0055] Thus, when the casing temperature of air compressor 2 is too high and the flow valve reaches its maximum opening, it indicates that the cooling effect of the cooling channel on air compressor 2 is already relatively limited. At this time, by connecting the liquid channel to the second cooling circuit, the cooling capacity of the cooling channel can be further improved to quickly reduce the temperature of air compressor 2 and keep the casing of air compressor 2 below the first specified temperature.

[0056] In some embodiments, the temperature of the coolant in the first cooling circuit is higher than the temperature of the coolant in the second cooling circuit. Controlling the connection state of the liquid passage includes: when the liquid passage is connected to the second cooling circuit and the housing temperature of the air compressor 2 does not meet the specified high temperature condition, controlling the liquid passage to be connected to the first cooling circuit.

[0057] Since the second cooling circuit also needs to cool other parts of the vehicle, when the housing temperature of the air compressor 2 does not meet the specified high temperature conditions, the air compressor 2 can be connected to the first cooling circuit to improve the cooling effect of the second cooling circuit on other parts. This can improve the cooling effect of the second cooling circuit on other parts of the vehicle while ensuring that the housing temperature of the air compressor 2 is within a stable range.

[0058] In some embodiments, the status data also includes the vehicle's ambient temperature. When the vehicle's ambient temperature meets low-temperature conditions, the second cooling circuit switches to a heating circuit. Controlling the connection status of the liquid passage includes: when the vehicle's ambient temperature meets low-temperature conditions and the air compressor 2's housing temperature meets a specified low-temperature condition, controlling the liquid passage to connect with the second cooling circuit.

[0059] In this way, when the ambient temperature of the vehicle is low, some internal devices may struggle to operate stably at low temperatures. In such cases, the second cooling circuit can be used to heat certain parts of the vehicle's interior to ensure the stability of these devices. Conversely, when the temperature of the air compressor 2 meets the specified low-temperature conditions, it may experience stalling or difficulty starting. Therefore, by connecting the liquid passage to the second cooling circuit, the liquid passage can be used to heat the air compressor 2, increasing its casing temperature and reducing the likelihood of stalling or difficulty starting.

[0060] Optionally, the low-temperature condition is that the ambient temperature of the vehicle is lower than a second specified temperature, and the specified low-temperature condition is that the housing temperature of the air compressor 2 is lower than a third specified temperature. Of course, the low-temperature condition can also be that the ambient temperature of the vehicle is lower than or equal to the second specified temperature, and the specified low-temperature condition can also be that the housing temperature of the air compressor 2 is lower than or equal to the third specified temperature. This disclosure does not limit this aspect.

[0061] Optionally, the ambient temperature of the vehicle can be the temperature inside the vehicle's front compartment, the temperature outside the vehicle, or a virtual value calculated based on the temperature inside the vehicle's front compartment and the temperature outside the vehicle.

[0062] Optionally, the detection assembly also includes a second temperature sensor and a third temperature sensor, the second temperature sensor being located inside the front compartment and the third temperature sensor being located outside the vehicle, to check the temperature of the front compartment and the outside of the vehicle, respectively.

[0063] Furthermore, when the ambient temperature of the vehicle meets the low-temperature requirements, the vehicle can be considered to be in winter or in a relatively cold environment; conversely, when the ambient temperature does not meet the low-temperature requirements, the vehicle can be considered to be in summer or in a relatively hot environment. Therefore, the cooling system can be adjusted based on different ambient temperatures or seasonal information to ensure that the air compressor 2 always operates within a suitable temperature range.

[0064] The second specified temperature can be a preset temperature or a temperature that the user can adjust himself / herself; this embodiment of the present disclosure does not limit this.

[0065] Similarly, the third specified temperature can be a preset temperature or a temperature that the user can adjust himself / herself; this disclosure does not limit this.

[0066] In some embodiments, controlling the connection state of the liquid passage further includes: when the ambient temperature of the vehicle meets the low temperature condition and the housing temperature of the air compressor 2 does not meet the specified low temperature condition, controlling the liquid passage to connect with the first cooling circuit.

[0067] Similar to the above description, when the ambient temperature of the vehicle is low, some internal devices struggle to operate stably at these temperatures, and the second cooling circuit can only heat a portion of the vehicle. When the casing temperature of the air compressor 2 does not meet the specified low-temperature conditions, it indicates that the air compressor 2 is already operating within a stable temperature range. At this point, by connecting the liquid passage to the first cooling circuit, the air compressor 2 can heat the refrigerant within the first cooling circuit, allowing the first cooling circuit to heat another part of the vehicle. This recovers the waste heat from the air compressor 2, thereby improving the vehicle's energy efficiency.

[0068] Based on the same concept, this disclosure also provides a vehicle that includes the cooling system described above.

[0069] In a vehicle, the cooling system provided in this embodiment can be used to liquid cool the air compressor 2 by connecting the cooling jacket 1 to the cooling circuit inside the vehicle. Compared with air cooling, this can improve the heat dissipation effect of the air compressor 2, thereby reducing the possibility of the air compressor 2 overheating and thus improving the service life of the air compressor 2.

[0070] This disclosure does not specifically limit the type of vehicle, such as cars, buses, trucks, sport utility vehicles (SUVs), etc. The vehicle can be a gasoline vehicle, a pure electric vehicle (BEV or EV), or a hybrid electric vehicle (HEV), such as a range-extended vehicle or a plug-in hybrid vehicle.

[0071] Taking this vehicle as an example of a new energy vehicle, the second cooling circuit is a circuit for cooling or heating the battery pack, and the first cooling circuit is a circuit located below the front compartment of the vehicle.

[0072] Furthermore, in vehicles, the cooling system provided in this embodiment can also protect the air compressor 2 through the cooling jacket 1. For example, when the vehicle is operating in a water-filled environment, the cooling jacket 1 can reduce the possibility of the air compressor 2 coming into contact with water, thereby reducing the possibility of corrosion of the air compressor 2 and thus improving the service life of the air compressor 2.
