Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] The embodiment of the present invention provides a cooling device for a vehicle sealed chamber, which can solve the problems in the related art that the salt and humidity in the port air are relatively high and easily corrode the controller, and the heat dissipation performance of the controller in the sealed box is poor.

[0025] See Figure 1As shown, a vehicle sealing chamber cooling device provided by an embodiment of the present invention may include: a sealing chamber 12. In this embodiment, the shape of the sealing chamber 12 is a cube. In other embodiments, the shape of the sealing chamber 12 may be other shapes. A controller 13 may be provided inside the sealing chamber 12. In this embodiment, there may be multiple controllers 13. The controller 13 may be an autonomous driving domain controller 13, a vision processor, an ultrasonic processor, etc. The sealing chamber 12 may be provided with a first communication port and a second communication port. In this embodiment, the first communication port and the second communication port may be respectively located on two adjacent side walls of the sealing chamber 12. In other embodiments, the first communication port and the second communication port may be respectively located on two opposite side walls of the sealing chamber 12; a communication air duct 11. The communication air duct 11 may be provided outside the sealing chamber 12. In this embodiment, the communication air duct 11 is a circular pipe. One end of the communication air pipe may be communicated with the first communication port, and the hot air inside the sealing chamber 12 may enter the communication air pipe from the first communication port; a heat dissipation structure. The heat dissipation structure may include a radiator 16, a wind shield, and a first fan 15. Among them, in this embodiment, the shape of the wind shield may be a cube. In other embodiments, the shape of the wind shield may be other shapes. The wind shield may be provided on the outer side wall of the sealing chamber 12, and the wind shield is installed on the side of the sealing chamber 12 where the second communication port is provided. The wind shield may cover the second communication port. The wind shield and the sealing chamber 12 may be hermetically connected to form a sealed space. The other end of the communication air duct may be communicated with the wind shield, and the hot air inside the sealing chamber 12 may enter the wind shield through the communication air duct; the radiator 16 may be located inside the wind shield. In this embodiment, the radiator 16 may be a water-cooled plate. In other embodiments, the radiator 16 may be other structures with heat dissipation functions. The radiator 16 may have a first coolant inside. The hot air inside the wind shield may pass through the radiator 16 to reduce the temperature. The cooled cold air may then enter the sealing chamber 12 from the second communication port to cool the controller 13; the first fan 15. The first fan 15 may be located inside the sealed space. The first fan 15 may blow the air inside the sealing chamber 12 to accelerate the air flow inside the sealing chamber 12, so that the air inside the sealing chamber 12 realizes internal circulation through the communication air duct 11. In this embodiment, the first fan 15 may be provided at the second communication port. In other embodiments, the first fan 15 may be provided at the first communication port. When the internal temperature of the controller 13 exceeds the temperature value set by the system, the first fan 15 and the radiator 16 start to work. The high-temperature gas near the controller 13 flows to the vicinity of the radiator 16 through the communication air duct 11. The first coolant may flow inside the radiator 16. The first coolant may reduce the temperature of the gas near the radiator 16. The gas with reduced temperature then returns to the vicinity of the controller 13 to cool the controller 13. The controller 13 can be cooled by the internal circulation of the gas in the sealed space. Therefore, it is possible to prevent the external air from corroding the controller 13 and have a good heat dissipation effect.

[0026] SeeFigure 1 As shown, in some embodiments, the radiator 16 may be provided with a first water inlet and a first water outlet. The heat dissipation structure may further include: a heat exchanger 6. In this embodiment, the heat exchanger 6 may have four openings, which may be a refrigerant outlet 61, a refrigerant inlet 64, a heat medium outlet 63, and a heat medium inlet 62 respectively. The refrigerant outlet 61 of the heat exchanger 6 may be communicated with the first water inlet, and the heat medium inlet 62 of the heat exchanger 6 may be communicated with the first water outlet. The first coolant in the radiator 16 may circulate between the radiator 16 and the heat exchanger 6. After absorbing heat, the temperature of the first coolant in the radiator 16 becomes higher, and it flows out of the radiator 16 from the first water outlet and flows into the heat exchanger 6 from the heat medium inlet 62. The first coolant may release heat in the heat exchanger 6 to reduce the temperature, and the cooled first coolant may flow out of the heat exchanger 6 from the refrigerant outlet 61 and flow into the radiator 16 from the first water inlet to continue cooling the gas near the radiator 16; an air-conditioning compressor 4, and the air-conditioning compressor 4 may be communicated with the heat medium outlet 63 of the heat exchanger 6; a condenser 1, one side of the condenser 1 may be communicated with the air-conditioning compressor 4, and the other side of the condenser 1 may be communicated with the refrigerant inlet 64 of the heat exchanger 6. In this embodiment, a first heat exchange tube is communicated between the refrigerant outlet 61 and the heat medium inlet 62, and a second heat exchange tube is communicated between the refrigerant inlet 64 and the heat medium outlet 63. The first heat exchange tube and the second heat exchange tube may exchange heat. The first coolant flows through the first heat exchange tube, and the second coolant flows through the second heat exchange tube. After the first coolant absorbs heat, it flows into the heat exchanger 6. Inside the heat exchanger 6, the second coolant absorbs the heat of the first coolant and then flows out from the heat medium outlet 63 and into the air-conditioning compressor 4. After passing through the air-conditioning compressor 4, the second coolant becomes a high-temperature and high-pressure gas state, and then enters the condenser 1. Inside the condenser 1, it releases heat and becomes a liquid state. The cooled second coolant then enters the heat exchanger 6 through the refrigerant inlet 64 to continue absorbing the heat of the first coolant, so that the first coolant maintains a low temperature state and continuously reduces the temperature of the controller 13.

[0027] See Figure 1 As shown, in some embodiments, the heat dissipation structure may further include: a dryer 20. The dryer 20 may be disposed between the condenser 1 and the heat exchanger 6. One side of the dryer 20 may be communicated with the condenser 1, and the other side of the dryer 20 may be communicated with the refrigerant inlet 64 of the heat exchanger 6. That is, after the second coolant is cooled by the condenser 1, it enters the dryer 20 and is dried, and then flows into the heat exchanger 6 through the refrigerant inlet 64, which can keep the second coolant dry and increase the cooling effect.

[0028] See Figure 1As shown, in some embodiments, the heat dissipation structure may further include: an expansion valve 19. The expansion valve 19 may be disposed between the condenser 1 and the heat exchanger 6. One side of the expansion valve 19 may communicate with the condenser 1, and the other side of the expansion valve 19 may communicate with the refrigerant inlet 64 of the heat exchanger 6. In this embodiment, a dryer 20 and an expansion valve 19 may be provided simultaneously, and the dryer 20 communicates with the expansion valve 19. The dryer 20 may communicate with the condenser 1, and the expansion valve 19 may communicate with the refrigerant inlet 64 of the heat exchanger 6. After the second coolant passes through the expansion valve 19 to reduce the pressure and flow rate, the second coolant may become a low-temperature and low-pressure liquid, which can further enhance the cooling effect.

[0029] See Figure 1 As shown, in some embodiments, the heat dissipation structure may further include: a first temperature and pressure sensor 3. The first temperature and pressure sensor 3 may be disposed between the air-conditioning compressor 4 and the condenser 1, and the first temperature and pressure sensor 3 may detect the pressure of the second coolant flowing out of the air-conditioning compressor 4. A second temperature and pressure sensor 5. The second temperature and pressure sensor 5 may be disposed between the air-conditioning compressor 4 and the heat exchanger 6, and the second temperature and pressure sensor 5 may detect the pressure of the second coolant flowing out of the heat exchanger 6. In this embodiment, a third temperature and pressure sensor 21 may also be provided. The third temperature and pressure sensor 21 may be disposed between the condenser 1 and the dryer 20, and the third temperature and pressure sensor 21 may be used to detect the second coolant flowing out of the condenser 1. The temperature and pressure of the second coolant may be monitored in real time through the first temperature and pressure sensor 3, the second temperature and pressure sensor 5, and the third temperature and pressure sensor 21. When the pressure of the second coolant is greater than the preset pressure, the rotational speed of the air-conditioning compressor 4 may be reduced, that is, the pressure of the second coolant may be decreased. When the pressure of the second coolant is less than the preset pressure, the rotational speed of the air-conditioning compressor 4 may be increased, that is, the pressure of the second coolant may be increased. The pressure and temperature of the second coolant may be monitored in real time by setting multiple sensors, and then the rotational speed of the air-conditioning compressor 4 may be controlled to make the vehicle-mounted sealed compartment cooling device operate more stably.

[0030] See Figure 1 and Figure 2As shown, in some embodiments, the vehicle sealing chamber cooling device may further include: a three-way solenoid valve 8, which may have a first port, a second port, and a third port. The first port may be communicated with the first water outlet, and the second port may be communicated with the heat medium inlet 62 of the heat exchanger 6; a plurality of power batteries 9. In this embodiment, the plurality of power batteries 9 may be connected in parallel. In other embodiments, the plurality of power batteries 9 may be connected in series. One side of the power battery 9 may be communicated with the refrigerant outlet 61 of the heat exchanger 6 through a first connecting pipe, and the other side of the power battery 9 may be communicated with the third port through a second connecting pipe. A third temperature sensor may be provided inside the power battery 9, and the third temperature sensor may detect the temperature of the power battery 9. Wherein, when the third temperature sensor detects that the temperature of the power battery 9 is higher than the preset temperature, the three-way solenoid valve 8 may open the second port and the third port and close the first port, so that the first coolant flows into the power battery 9. After the first coolant cools the power battery 9, it flows out of the power battery 9, and the first coolant flows into the heat exchanger 6 from the heat medium inlet 62; when the third temperature sensor detects that the temperature of the power battery 9 is lower than the preset temperature, the three-way solenoid valve 8 may open the first port and the second port and close the third port. The first coolant may continue to circulate between the radiator 16 and the heat exchanger 6 to continuously dissipate heat from the controller 13. By providing the three-way solenoid valve 8, heat dissipation of the power battery 9 can be achieved, the usage range of the vehicle sealing chamber 12 cooling device can be increased, and the safety of the vehicle can be ensured.

[0031] See Figure 1 As shown, in some embodiments, the heat dissipation structure may further include: a water pump 17, which may be arranged between the heat exchanger 6 and the radiator 16. In this embodiment, one side of the water pump 17 may be communicated with the refrigerant outlet 61 of the heat exchanger 6, and the other side of the water pump 17 may be communicated with the first water inlet of the radiator 16. In other embodiments, one side of the water pump 17 may be communicated with the first water outlet of the radiator 16, and the other side of the water pump 17 may be communicated with the heat medium inlet 62 of the heat exchanger 6. The water pump 17 can increase the flow rate of the first coolant and further increase the cooling effect.

[0032] See Figure 1As shown, in some embodiments, the heat dissipation structure may further include: a first temperature sensor 7, which may be disposed at the heat medium inlet 62 of the heat exchanger 6, and the first temperature sensor 7 may detect the temperature of the first coolant flowing out of the radiator 16; a second temperature sensor 18 may be disposed at the refrigerant outlet 61 of the heat exchanger 6, and the second temperature sensor 18 may detect the temperature of the first coolant flowing out of the heat exchanger 6. By the first temperature sensor 7 and the second temperature sensor 18, the temperature of the first coolant can be collected in real time, and the temperature inside the sealed chamber 12 can be accurately controlled to avoid the environment inside the sealed chamber 12 from being too cold or too hot, ensuring that the controller 13 is maintained at the optimal working temperature.

[0033] See Figure 1 As shown, in some embodiments, a partition may be provided inside the sealed chamber 12. The partition may divide the sealed chamber 12 into two spaces. One or more controllers 13 may be respectively provided on opposite sides of the partition. The multiple controllers 13 may be arranged in layers. The partition may be provided with a plurality of ventilation holes. In this embodiment, the first communication port and the second communication port may be respectively located on opposite sides of the partition. The controllers 13 with relatively large heat generation among the multiple controllers 13 may be arranged on the side of the sealed chamber 12 close to the radiator 16. The side of the sealed chamber 12 close to the radiator 16 is the inlet of cold air, and the heat dissipation effect on this side is better than that on the side of the sealed chamber 12 far from the radiator 16, which can keep the multiple controllers 13 maintained within a similar temperature range.

[0034] See Figure 1 As shown, in some embodiments, the heat dissipation structure may further include: a drainage bag, which may be disposed at the bottom of the radiator 16. The water condensed on the radiator 16 may flow along the radiator 16 into the drainage bag, and the drainage bag may collect the condensed water. When the condensed water needs to be discharged, the wind shield can be removed, and then the condensed water in the drainage bag can be discharged, which can ensure that the air inside the sealed chamber 12 is dry and the controller 13 is in a dry working environment.

[0035] See Figure 1 As shown, in some embodiments, the heat dissipation structure may further include: a second fan 2, which may be disposed on one side of the condenser 1. The second coolant flows into the condenser 1 after passing through the air conditioner compressor 4. The second fan 2 may be turned on to blow away the hot air around the second coolant, further increasing the cooling effect.

[0036] The principle of a vehicle-mounted sealed chamber cooling device provided by an embodiment of the present invention is:

[0037] Since a controller 13 can be provided in the sealed chamber 12, the sealed chamber 12 can be provided with a first communication port and a second communication port. The first communication port and the second communication port can be respectively located on opposite side walls of the sealed chamber 12. The communication air duct 11 can be provided outside the sealed chamber 12. One end of the communication air pipe can be communicated with the first communication port. The hot air in the sealed chamber 12 can enter the communication air pipe from the first communication port. The wind protection cover is installed on the side of the sealed chamber 12 where the second communication port is provided. The wind protection cover can cover the second communication port. The wind protection cover and the sealed chamber 12 can be hermetically connected to form a sealed space. The other end of the communication air pipe can be communicated with the wind protection cover. The hot air in the sealed chamber 12 can enter the wind protection cover through the communication air pipe. The radiator 16 can be located in the wind protection cover. The radiator 16 can have a first coolant inside. The hot air in the wind protection cover can pass through the radiator 16 to reduce the temperature. The cooled cold air can then enter the sealed chamber 12 from the second communication port to cool the controller 13. The first fan 15 can be located in the sealed space. The first fan 15 can blow the air in the sealed chamber 12 to accelerate the air flow in the sealed chamber 12, so that the air in the sealed chamber 12 can realize internal circulation through the communication air duct 11. When it is necessary to cool the controller 13, the first fan 15 and the radiator 16 start to work. The high-temperature gas near the controller 13 flows to the vicinity of the radiator 16 through the communication air duct 11. The first coolant can flow inside the radiator 16. The first coolant can reduce the temperature of the gas near the radiator 16. The gas with reduced temperature then returns to the vicinity of the controller 13 to cool the controller 13. The controller 13 can be cooled through the internal circulation of the gas in the sealed space. Therefore, the external air can be prevented from corroding the controller 13, and a better heat dissipation effect can be achieved.
