For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to the specific circumstances.

[0046] The following combination Figures 1-8 A cooling assembly 100 and a vehicle having the same according to an embodiment of the present invention will be described in detail.

[0047] Reference Figure 1 and Figure 2As shown, the cooling component 100 according to an embodiment of the present invention includes: a liquid storage pot 10 and a first liquid pump 20. The liquid storage pot 10 includes: a pot body 1 and a first partition 2. The pot body 1 has a first liquid storage chamber 11, a first liquid inlet 12 and a first liquid outlet 13. The first partition 2 is arranged in the first liquid storage chamber 11 and divides the first liquid storage chamber 11 into a first liquid inlet chamber 111 and a first liquid outlet chamber 112. The first liquid inlet 12 is connected to the first liquid inlet chamber 111, and the first liquid outlet 13 is connected to the first liquid outlet chamber 112. The first partition 2 has a first communicating hole 21. The first communicating hole 21 connects the first liquid inlet chamber 111 and the first liquid outlet chamber 112, and the first liquid inlet 12 is staggered with the first communicating hole 21. The first liquid pump 20 is installed on the liquid storage pot 10. The first liquid pump 20 is connected to the first liquid outlet 13. The first liquid pump 20 is used to pump out the cooling liquid in the first liquid outlet chamber 112.

[0048] It should be noted that the first liquid outlet 13 can be connected to the inlet of the first heating element of the vehicle through the first liquid pump 20, and the first liquid inlet 12 can be connected to the outlet of the first heating element. The first liquid pump 20 can pump the coolant in the first liquid outlet cavity 112 from the first liquid outlet 13 to the inlet of the first heating element to cool the first heating element with the coolant. The coolant can then flow through the outlet of the first heating element to the first liquid inlet 12, achieving a circulating flow of the coolant. The cooling assembly 100 may also include a first radiator, which can be located between the first liquid pump 20 and the inlet of the first heating element, or between the outlet of the first heating element and the first liquid inlet 12. The first radiator is suitable for cooling the circulating coolant. The first heating element may be a battery pack.

[0049] It can be understood that the coolant after heat exchange with the first heating element may carry air, coolant vapor and other gases when flowing back into the kettle body 1. When the mixture of coolant and gas flows from the first liquid inlet 12 to the first liquid outlet 13, the coolant sinks under its own gravity and the gas rises. The gas can rise above the liquid surface of the coolant to achieve degassing of the coolant, thereby reducing the gas flowing into the first liquid pump 20 from the first liquid inlet 12 and reducing the gas pumped to the first heating element by the first liquid pump 20, which is beneficial to improving the cooling effect of the coolant on the first heating element.

[0050] By staggering the first liquid inlet 12 and the first connecting hole 21, the flow path from the first liquid inlet 12 to the first liquid outlet 13 can be increased, thereby increasing the flow time of the mixture composed of the coolant and gas flowing from the first liquid inlet 12 to the first liquid outlet 13, so that the coolant and the gas can be fully separated and the degassing efficiency can be improved. The first partition 2 can prevent the gas entering from the first liquid inlet 12 from flowing directly to the first liquid outlet 13, so that the gas has sufficient time to rise and separate from the coolant.

[0051] In addition, the first liquid storage chamber 11, the first liquid pump 20 and the first heating element can form a closed loop connected in series, that is, the coolant in the first liquid storage chamber 11 can first be pumped to the first heating element by the first liquid pump 20, and the coolant can flow back to the first liquid storage chamber 11 after cooling and dissipating the heat of the first heating element. Compared with the method in the related art in which a part of the coolant flows back to the kettle through the degassing port on the kettle after cooling and dissipating the heat of the first heating element, and the other part flows directly to the water pump, the coolant in this embodiment can flow back to the first liquid storage chamber 11 after cooling and dissipating the heat of the first heating element, and be degassed in the first liquid storage chamber 11, and the degassing efficiency is higher, and the first liquid pump 20 is installed on the liquid storage pot 10, and the first liquid pump 20 and the liquid storage pot 10 can form an integrated series structure, and the first liquid pump 20 and the liquid storage pot 10 do not need to be connected by a pipeline, which is conducive to simplifying the structure of the cooling component 100 and reducing the cost of the cooling component 100.

[0052] According to the cooling component 100 of the embodiment of the present invention, a first partition 2 is provided in the liquid storage pot 10 thereof, and the first connecting hole 21 of the first partition 2 is staggered with the first liquid inlet 12 of the liquid storage pot 10, which can increase the flow path from the first liquid inlet 12 to the first liquid outlet 13 of the liquid storage pot 10, and prevent the gas entering the first liquid storage cavity 11 from the first liquid inlet 12 from flowing directly to the first liquid outlet 13, so as to facilitate the full separation of the coolant and the gas, which is beneficial to improving the degassing efficiency and improving the cooling effect of the coolant.

[0053] In some embodiments of the present invention, the first partition 2 includes: multiple first sub-partitions connected at an angle, at least one first sub-partition has a first connecting hole 21. When only one first sub-partition has the first connecting hole 21, the flow path of the coolant can be precisely controlled. When multiple first sub-partitions have the first connecting holes 21, the multiple first connecting holes 21 can increase the circulation area of ​​the coolant, thereby reducing the flow resistance of the coolant from the first liquid inlet chamber 111 to the first liquid outlet chamber 112.

[0054] It can be understood that multiple first sub-partitions are connected at an angle to form a winding first partition 2. For example, the first partition 2 can be a "V"-shaped or "W"-shaped partition, which is beneficial to further increase the flow path of the coolant, so that the coolant and gas are fully separated, which is beneficial to further improve the degassing efficiency.

[0055] In some embodiments of the present invention, referring to Figure 1 and Figure 2As shown, the kettle body 1 also has a first adapter port 14, the first liquid pump 20 has a first liquid suction port 201 and a first liquid discharge port, the first liquid suction port 201 is connected with the first liquid outlet 13, and the first liquid discharge port is connected with the first adapter port 14, the coolant in the first liquid storage chamber 11 can flow to the first liquid suction port 201 through the first liquid outlet 13, the first liquid pump 20 can suck the coolant through the first liquid suction port 201, and can pump the coolant to the first adapter port 14 through the first liquid discharge port.

[0056] It can be understood that the first adapter port 14 is suitable for being connected to the inlet of the first heating element. The first adapter port 14 is arranged on the kettle body 1. There is no need to set a structure for connecting to the first heating element on the first liquid pump 20, which is beneficial to simplify the structure of the first liquid pump 20. In addition, when the connection between the first adapter port 14 and the first heating element fails, there is no need to disassemble the first liquid pump 20 for maintenance, which is beneficial to improving the convenience of maintenance of the cooling assembly 100.

[0057] It should be noted that the first adapter port 14 and the first liquid inlet 12 of the kettle body 1 are respectively connected to the inlet and outlet of the first heating element. The coolant pumped from the first discharge port to the first adapter port 14 can flow into the first heating element through the inlet of the first heating element. After the coolant cools and dissipates the heat of the first heating element, it can flow back into the kettle body 1 through the outlet of the first heating element and the first liquid inlet 12 of the kettle body 1 in turn, thereby realizing the circulation flow and temperature control of the coolant.

[0058] In some embodiments of the present invention, referring to Figure 1 As shown, the liquid storage pot 10 also includes a first reinforcing plate 3, which is arranged in the first liquid storage cavity 11. The first reinforcing plate 3 is respectively connected to the first partition 2 and the inner wall of the first liquid storage cavity 11. The first reinforcing plate 3 can reliably support the first partition 2, which is beneficial to improving the connection strength between the first partition 2 and the inner wall of the first liquid storage cavity 11, and improving the load resistance of the first partition 2.

[0059] Reference Figure 1 As shown, the first reinforcing plate 3 is arranged on the side away from the first liquid inlet chamber 111 to avoid increasing the flow resistance of the coolant flowing from the first liquid inlet chamber 111 to the first liquid outlet chamber 112. The first reinforcing plate 3 and the first partition plate 2 can form an "I"-shaped structural plate, which can effectively improve the connection strength between the first partition plate 2 and the inner wall of the first liquid storage chamber 11, and improve the ability of the first partition plate 2 to resist impact.

[0060] In some embodiments of the present invention, referring to Figure 1 As shown, the first liquid outlet 13 is opened on the bottom wall of the first liquid storage chamber 11, which is conducive to the full separation of gas and coolant.

[0061] It can be understood that since the density of the gas is less than the density of the coolant, when the gas and the coolant are separated, the gas rises and the coolant sinks. The first liquid outlet 13 is opened on the bottom wall of the first liquid storage chamber 11, which can prevent the gas from flowing into the first liquid outlet 13 together with the coolant during the rising process, thereby facilitating the full separation of the gas and the coolant.

[0062] In addition, refer to Figure 1 As shown, the first liquid pump 20 is arranged at the bottom of the liquid storage pot 10. By opening the first liquid outlet 13 on the bottom wall of the first liquid storage chamber 11, the flow path from the first liquid outlet 13 to the first liquid suction port 201 of the first liquid pump 20 can be shortened, which is beneficial to reducing the power lost by the coolant during the flow process, so that the coolant in the first liquid storage chamber 11 flows to the first liquid suction port 201, which is beneficial to reducing the risk of air entrapment in the first liquid pump 20.

[0063] In some embodiments of the present invention, referring to Figure 1 and Figure 2 As shown, the first liquid inlet 12 is located below the lowest liquid level mark 113 of the first liquid storage chamber 11 , which is beneficial to reducing the number of bubbles generated by the flow of coolant from the first liquid inlet 12 to the first liquid storage chamber 11 .

[0064] It can be understood that when the cooling component 100 is in normal use, the liquid level of the coolant in the first liquid storage chamber 11 is higher than or equal to the height of the minimum liquid level mark 113 to ensure that the content of coolant in the first liquid storage chamber 11 is sufficient. The first liquid inlet 12 is located below the minimum liquid level mark 113 of the first liquid storage chamber 11. When the coolant flows from the first liquid inlet 12 to the first liquid storage chamber 11, a water flow can be formed. The coolant can flow below the liquid level of the coolant in the first liquid storage chamber 11, which is beneficial to reduce water flow noise and improve NVH (Noise, Vibration, Harshness) performance, and can avoid the coolant from contacting with air when flowing from the first liquid inlet 12 into the first liquid storage chamber 11, which is beneficial to reduce the number of bubbles formed by the water flow impacting the coolant in the first liquid storage chamber 11.

[0065] Reference Figure 2 As shown, the first adapter port 14 and the first liquid inlet 12 can be located at the same height. When the first adapter port 14 is connected to the pipeline for connecting to the inlet of the first heating element, and the first liquid inlet 12 is connected to the pipeline for connecting to the outlet of the first heating element, operations can be performed at the same height, which is convenient for plug-in assembly of the pipelines.

[0066] In some embodiments of the present invention, referring to Figure 3-Figure 5As shown, the kettle body 1 also has a first filling port 15 connected to the first liquid storage chamber 11. The first filling port 15 is constructed as a hollow cylindrical structure. The outer peripheral surface of the first filling port 15 has a first external thread 151. The liquid storage kettle 10 also includes: a first kettle cover 4, the first kettle cover 4 includes: a first inner cover 41, a first outer cover 42, a first air inlet check valve 43 and a first air outlet check valve 44. The top surface of the first inner cover 41 and the first filling port 15 facing away from the first liquid storage chamber 11 The first outer cover 42 is connected to the first inner cover 41, and the first outer cover 42 and the first inner cover 41 jointly define a first ventilation cavity 45. The inner circumferential surface of the first outer cover 42 has a first internal thread 421 and a first ventilation groove 422. The first internal thread 421 is threadedly matched with the first external thread 151. The first ventilation cavity 45 is connected to the atmosphere through the first ventilation groove 422. The first air inlet check valve 43 and the first air outlet check valve 44 are both penetrated and fixed to the first inner cover 41.

[0067] It can be understood that the first internal thread 421 is suitable for threaded cooperation with the first external thread 151, and the first pot cover 4 can be detachably installed on the pot body 1. When it is necessary to add coolant to the first liquid storage chamber 11, the first pot cover 4 can be removed from the pot body 1 to add coolant to the first liquid storage chamber 11 through the first filling port 15. After the coolant filling is completed, the first pot cover 4 can be installed to the pot body 1 to avoid leakage of the coolant stored in the first liquid outlet chamber 112.

[0068] When the gas pressure in the first liquid storage chamber 11 is lower than the preset pressure, the first air inlet check valve 43 opens, and air in the atmosphere can flow into the first vent chamber 45 through the first vent groove 422, and then enter the first liquid storage chamber 11 through the first air inlet check valve 43, thereby replenishing the first liquid storage chamber 11 and preventing the formation of negative pressure in the first liquid storage chamber 11, so as to facilitate the first liquid pump 20 to suck the coolant in the first liquid storage chamber 11. When the gas pressure in the first liquid storage chamber 11 is greater than the preset pressure, the first air outlet check valve 44 opens, and the gas can be discharged into the first vent chamber 45 through the first air outlet check valve 44, and then discharged to the atmosphere through the first vent groove 422.

[0069] In some embodiments of the present invention, the kettle body 1 has at least one connecting arm 16, and the connecting arm 16 is suitable for being connected to the vehicle body so that the liquid storage kettle 10 is fixed to the vehicle body.

[0070] Reference Figure 2 and Figure 3As shown, the kettle body 1 has three connecting arms 16, which are the first connecting arm 161, the second connecting arm 162 and the third connecting arm 163. The first connecting arm 161 and the second connecting arm 162 are located on the left and right sides respectively, and the third connecting arm 163 is located at the bottom of the kettle body 1. The kettle body 1 can be connected to the vehicle body at three different positions through the three connecting arms 16, which is beneficial to improving the connection strength between the kettle body 1 and the vehicle body.

[0071] Reference Figure 2 、 Figure 3 and Figure 8 As shown, the cooling assembly 100 further includes a first buffer pad 30, a fixing column 40 and a second buffer pad 50, the first connecting arm 161 and the second connecting arm 162 both have a mounting groove 1611, the first buffer pad 30 is suitable for passing through the mounting groove 1611, the fixing column 40 is passed through the first buffer pad 30, the fixing column 40 has a mounting hole 401, and a fastener can be used to pass through the mounting hole 401 and connected to the vehicle body, so that the first connecting arm 161 and the second connecting arm 162 are both fixedly connected to the vehicle body, and the third connecting arm 163 is formed. It is a columnar structure, and the third connecting arm 163 is suitable for inserting into the limiting hole on the vehicle body to achieve the limitation of the kettle body 1, wherein the installation groove 1611 can be a "C"-shaped groove, and the first buffer pad 30 and the second buffer pad 50 can play the role of vibration reduction and buffering, which is beneficial to reduce the risk of abnormal vibration and noise. The fixing column 40 can play the role of supporting fasteners, which is beneficial to enhance the connection strength between the first connecting arm 161 and the second connecting arm 162 and the vehicle body respectively. The fasteners can be screws, and the fasteners can also be fastening bolts and fastening nuts.

[0072] In some embodiments of the present invention, referring to Figure 1 As shown, the kettle body 1 has a second liquid storage chamber 17, a second liquid inlet 18 and a second liquid outlet 19, and the liquid storage kettle 10 also includes: a second partition plate 5, the second partition plate 5 is arranged in the second liquid storage chamber 17 and divides the second liquid storage chamber 17 into a second liquid inlet chamber 171 and a second liquid outlet chamber 172, the second liquid inlet 18 is connected to the second liquid inlet chamber 171, and the second liquid outlet 19 is connected to the second liquid outlet chamber 172, the second partition plate 5 has a second connecting hole 51, the second connecting hole 51 connects the second liquid inlet chamber 171 and the second liquid outlet chamber 172, and the second liquid inlet 18 is staggered with the second connecting hole 51, and the cooling component 100 also includes: a second liquid pump 60, the second liquid pump 60 is installed on the liquid storage chamber 10, the second liquid pump 60 is connected to the second liquid outlet 19, and the second liquid pump 60 is used to pump out the cooling liquid in the second liquid outlet chamber 172.

[0073] It should be noted that the second liquid outlet 19 can be connected to the inlet of the second heating element of the vehicle through the second liquid pump 60, and the outlet of the second heating element can be connected to the second liquid inlet 18. The second liquid pump 60 can pump the coolant in the second liquid outlet cavity 172 from the second liquid outlet 19 to the inlet of the second heating element to cool the second heating element with the coolant. The coolant can then flow through the outlet of the second heating element to the second liquid inlet 18, realizing the circulation of the coolant. The cooling assembly 100 may also include a second radiator, which can be arranged between the second liquid pump 60 and the inlet of the second heating element, or between the outlet of the second heating element and the second liquid inlet 18. The first radiator is suitable for cooling the circulating coolant. The second heating element may be a motor.

[0074] It can be understood that the coolant after heat exchange with the second heating element may carry air, coolant vapor and other gases when flowing back into the kettle body 1. When the mixture of coolant and gas flows from the second liquid inlet 18 to the second liquid outlet 19, the coolant sinks under its own gravity and the gas rises. The gas can rise above the liquid surface of the coolant to achieve degassing of the coolant, thereby reducing the gas flowing into the second liquid pump 60 from the second liquid inlet 18 and reducing the gas pumped to the second heating element by the second liquid pump 60, which is beneficial to improving the cooling effect of the coolant on the second heating element.

[0075] By staggering the second liquid inlet 18 and the second connecting hole 51, the flow path from the second liquid inlet 18 to the second liquid outlet 19 can be increased, thereby increasing the flow time of the mixture composed of the coolant and gas flowing from the second liquid inlet 18 to the second liquid outlet 19, so that the coolant and the gas are fully separated and the degassing efficiency is improved. The second partition 5 can prevent the gas entering from the second liquid inlet 18 from flowing directly to the second liquid outlet 19, so that the gas has sufficient time to rise and separate from the coolant.

[0076] In addition, the second liquid storage chamber 17, the second liquid pump 60 and the second heating element can form a closed loop in series, that is, the coolant in the second liquid storage chamber 17 can first be pumped to the second heating element by the second liquid pump 60, and the coolant can flow back into the second liquid storage chamber 17 after cooling and dissipating the heat of the second heating element. Compared with the method in the related art in which a part of the coolant flows back into the kettle through the degassing port on the kettle after cooling and dissipating the heat of the second heating element, and the other part flows directly to the water pump, the coolant in this embodiment can flow back into the second liquid storage chamber 17 after cooling and dissipating the heat of the second heating element, and be degassed in the second liquid storage chamber 17, with higher degassing efficiency, and the first liquid pump 20 is installed on the liquid storage pot 10, and the first liquid pump 20 and the liquid storage pot 10 can form an integrated series structure, and the first liquid pump 20 and the liquid storage pot 10 do not need to be connected by a pipeline, which is conducive to simplifying the structure of the cooling component 100 and reducing the cost of the cooling component 100.

[0077] In some embodiments of the present invention, the second partition 5 includes: multiple second sub-partitions connected at an angle, at least one second sub-partition has a second connecting hole 51. When only one second sub-partition has the second connecting hole 51, the flow path of the coolant can be precisely controlled. When multiple second sub-partitions have the second connecting holes 51, the multiple second connecting holes 51 can increase the circulation area of ​​the coolant, thereby reducing the flow resistance of the coolant from the second liquid inlet chamber 171 to the second liquid outlet chamber 172.

[0078] It can be understood that multiple second sub-partitions are connected at an angle to form a winding second partition 5. For example, the second partition 5 can be a "V"-shaped or "W"-shaped partition, which is beneficial to further increase the flow path of the coolant, so that the coolant and gas are fully separated, which is beneficial to further improve the degassing efficiency.

[0079] In some embodiments of the present invention, referring to Figure 1 and Figure 2 As shown, the kettle body 1 also has a second adapter port 101, the second liquid pump 60 has a second liquid suction port 601 and a second liquid discharge port 602, the second liquid suction port 601 is connected to the second liquid outlet 19, the second liquid discharge port 602 is connected to the second adapter port 101, the coolant in the second liquid storage chamber 17 can flow to the second liquid suction port 601 through the second liquid outlet 19, the second liquid pump 60 can suck in the coolant through the second liquid suction port 601, and can pump the coolant to the second adapter port 101 through the second liquid discharge port 602.

[0080] It can be understood that the second adapter port 101 is suitable for being connected to the inlet of the second heating element. The second adapter port 101 is arranged on the kettle body 1. There is no need to set a structure for connecting to the second heating element on the second liquid pump 60, which is conducive to simplifying the structure of the second liquid pump 60. In addition, when the connection between the second adapter port 101 and the second heating element fails, there is no need to disassemble the second liquid pump 60 for maintenance, which is conducive to improving the convenience of maintenance of the cooling component 100.

[0081] It should be noted that the second adapter 101 and the second liquid inlet 18 of the kettle body 1 are respectively connected to the inlet and outlet of the second heating element. The coolant pumped from the second drain port 602 to the second adapter 101 can flow into the second heating element through the inlet of the second heating element. After the coolant cools and dissipates the heat of the second heating element, it can flow back into the kettle body 1 through the outlet of the second heating element and the second liquid inlet 18 of the kettle body 1 in turn, thereby realizing the circulation flow and temperature control of the coolant.

[0082] In some embodiments of the present invention, referring to Figure 1As shown, the liquid storage pot 10 also includes a second reinforcing plate 6, which is arranged in the second liquid storage cavity 17. The second reinforcing plate 6 is respectively connected to the second partition 5 and the inner wall of the second liquid storage cavity 17. The second reinforcing plate 6 can reliably support the first partition 2, which is beneficial to improve the connection strength between the second partition 5 and the inner wall of the second liquid storage cavity 17, and improve the load resistance of the second partition 5.

[0083] Reference Figure 1 As shown, the second reinforcing plate 6 is arranged on the side away from the second liquid inlet chamber 171 to avoid increasing the flow resistance of the coolant flowing from the second liquid inlet chamber 171 to the second liquid outlet chamber 172. The second reinforcing plate 6 and the second partition plate 5 can form an "I"-shaped structural plate, which can effectively improve the connection strength between the second partition plate 5 and the inner wall of the second liquid storage chamber 17, and improve the ability of the second partition plate 5 to resist impact.

[0084] In some embodiments of the present invention, referring to Figure 1 As shown, the liquid storage pot 10 also includes a plurality of third reinforcing plates 7, wherein a part of the third reinforcing plates 7 are arranged in the first liquid storage cavity 11, and another part of the third reinforcing plates 7 are arranged in the second liquid storage cavity 17. The third reinforcing plates 7 located in the first liquid storage cavity 11 are respectively connected to the side walls and bottom walls of the first liquid outlet cavity 112, and the third reinforcing plates 7 can reliably support the side walls of the first liquid storage cavity 11. The third reinforcing plates 7 located in the second liquid storage cavity 17 are respectively connected to the side walls and bottom walls of the second liquid outlet cavity 172, and the third reinforcing plates 7 can reliably support the side walls of the second liquid storage cavity 17, which is beneficial to improving the structural strength of the pot body 1 and improving the load-bearing capacity of the pot body 1.

[0085] In some embodiments of the present invention, referring to Figure 1 As shown, the second liquid outlet 19 is opened on the bottom wall of the second liquid storage chamber 17, which is conducive to the full separation of gas and coolant.

[0086] It can be understood that since the density of the gas is less than the density of the coolant, when the gas and the coolant are separated, the gas rises and the coolant sinks. The second liquid outlet 19 is opened on the bottom wall of the second liquid storage chamber 17, which can prevent the gas from flowing into the second liquid outlet 19 together with the coolant during the rising process, thereby facilitating the full separation of the gas and the coolant.

[0087] In addition, refer to Figure 1 As shown, the second liquid pump 60 is arranged at the bottom of the liquid storage pot 10. By opening the second liquid outlet 19 on the bottom wall of the second liquid storage chamber 17, the flow path from the second liquid outlet 19 to the second liquid suction port 601 of the second liquid pump 60 can be shortened, which is beneficial to reducing the power lost by the coolant during the flow process, so that the coolant in the second liquid storage chamber 17 flows to the second liquid suction port 601, which is beneficial to reducing the risk of air entrapment in the second liquid pump 60.

[0088] In some embodiments of the present invention, referring to Figure 1 and Figure 2 As shown, the second liquid inlet 18 is located below the lowest liquid level mark 113 , which is beneficial to reducing the number of bubbles generated by the flow of coolant from the second liquid inlet 18 to the second liquid storage chamber 17 .

[0089] It can be understood that when the cooling component 100 is in normal use, the liquid level of the coolant in the second liquid storage chamber 17 is higher than or equal to the height of the minimum liquid level mark 113 to ensure that the content of coolant in the second liquid storage chamber 17 is sufficient. The second liquid inlet 18 is located below the minimum liquid level mark 113 of the second liquid storage chamber 17. When the coolant flows from the second liquid inlet 18 to the second liquid storage chamber 17, a water flow can be formed. The coolant can flow below the liquid level of the coolant in the second liquid storage chamber 17, which is beneficial to reduce water flow noise and improve NVH performance. It can also avoid the coolant from contacting with air when flowing from the second liquid inlet 18 into the second liquid storage chamber 17, which is beneficial to reduce the number of bubbles formed by the water flow impacting the coolant in the second liquid storage chamber 17.

[0090] Reference Figure 2 As shown, the second adapter 101 and the second liquid inlet 18 can be located at the same height. When the second adapter 101 is connected to the pipeline for connecting to the inlet of the second heating element, and the second liquid inlet 18 is connected to the pipeline for connecting to the outlet of the second heating element, operations can be performed at the same height, which is convenient for plugging and assembling the pipelines.

[0091] In some embodiments of the present invention, referring to Figure 3 、 Figure 6 and Figure 7 As shown, the kettle body 1 also has a second filling port 102 connected to the second liquid storage chamber 17, the second filling port 102 is constructed as a hollow cylindrical structure, and the outer peripheral surface of the second filling port 102 has a second external thread 1021. The liquid storage kettle 10 also includes: a second kettle cover 8, the second kettle cover 8 includes: a second inner cover 81, a second outer cover 82, a second air inlet check valve 83 and a second air outlet check valve 84, the second inner cover 81 and the second filling port 102 are away from the second liquid storage chamber 17. The top surfaces are abutted, the second outer cover 82 is connected to the second inner cover 81, and the second outer cover 82 and the second inner cover 81 jointly define a second ventilation cavity 85. The inner circumference of the second outer cover 82 has a second internal thread 821 and a second ventilation groove 822. The second internal thread 821 is threadedly engaged with the second external thread 1021. The second ventilation cavity 85 is connected to the atmosphere through the second ventilation groove 822. The second air inlet check valve 83 and the second air outlet check valve 84 are both fixed to the second inner cover 81.

[0092] It can be understood that the second internal thread 821 is suitable for threaded cooperation with the second external thread 1021, and the second pot cover 8 can be detachably installed on the pot body 1. When it is necessary to add coolant to the second liquid storage chamber 17, the second pot cover 8 can be removed from the pot body 1 to add coolant to the second liquid storage chamber 17 through the second filling port 102. After the coolant filling is completed, the second pot cover 8 can be installed to the pot body 1 to avoid leakage of the coolant stored in the second liquid outlet chamber 172.

[0093] When the gas pressure in the second liquid storage chamber 17 is lower than the preset pressure, the second air inlet one-way valve 83 opens, and the air in the atmosphere can flow to the second ventilation chamber 85 through the second ventilation groove 822, and then enter the second liquid storage chamber 17 through the second air inlet one-way valve 83 to replenish the second liquid storage chamber 17 and avoid the formation of negative pressure in the second liquid storage chamber 17, so as to facilitate the second liquid pump 60 to suck the coolant in the second liquid storage chamber 17. When the gas pressure in the second liquid storage chamber 17 is greater than the preset pressure, the second air outlet one-way valve 84 opens, and the gas can be discharged to the second ventilation chamber 85 through the second air outlet one-way valve 84, and then discharged to the atmosphere through the second ventilation groove 822.

[0094] In some embodiments of the present invention, referring to Figure 1 As shown, the second liquid outlet 19 is opened on the bottom wall of the second liquid storage chamber 17 to shorten the flow path from the second liquid outlet 19 to the second liquid suction port 601 of the second liquid pump 60, so that the coolant in the second liquid storage chamber 17 flows to the second liquid suction port 601 of the second liquid pump 60, which is beneficial to reduce the risk of air entrapment in the second liquid pump 60.

[0095] In some embodiments of the present invention, referring to Figure 1 As shown, the second liquid inlet 18 is located below the lowest liquid level mark 113 of the second liquid storage chamber 17 , which is beneficial to reducing the number of bubbles generated by the flow of coolant from the second liquid inlet 18 to the second liquid storage chamber 17 .

[0096] It can be understood that the liquid level of the coolant in the second liquid storage chamber 17 is higher than or equal to the height of the minimum liquid level mark 113 to ensure that the content of coolant in the second liquid storage chamber 17 is sufficient. The second liquid inlet 18 is located below the minimum liquid level mark 113 of the second liquid storage chamber 17. When the coolant flows from the second liquid inlet 18 to the second liquid storage chamber 17, a water flow can be formed. The coolant can flow below the liquid level of the coolant in the second liquid storage chamber 17, thereby reducing water flow noise and improving NVH performance. It can also avoid the coolant from contacting with air when flowing from the second liquid inlet 18 into the second liquid storage chamber 17, which is beneficial to reduce the number of bubbles formed by the water flow impacting the coolant in the second liquid storage chamber 17.

[0097] In some embodiments of the present invention, referring to Figure 1As shown, the liquid storage pot 10 also includes: an insulation component 9, which is arranged between the first liquid storage chamber 11 and the second liquid storage chamber 17. The insulation component 9 includes: a first insulation plate 91 and a second insulation plate 92 arranged at intervals, and an insulation chamber 94 is defined between the first insulation plate 91 and the second insulation plate 92. The insulation chamber 94 can reduce the heat exchange between the coolant in the first liquid storage chamber 11 and the coolant in the second liquid storage chamber 17, thereby avoiding affecting the cooling effect of the coolant in the first liquid storage chamber 11 and the coolant in the second liquid storage chamber 17.

[0098] In some embodiments of the present invention, referring to Figure 1 As shown, the insulation assembly 9 also includes a plurality of connecting plates 93, which are connected between the first insulation plate 91 and the second insulation plate 92. The plurality of connecting plates 93 can jointly support the first insulation plate 91 and the second insulation plate 92, which is beneficial to improving the load-bearing capacity of the first insulation plate 91 and the second insulation plate 92.

[0099] In some embodiments of the present invention, referring to Figure 8 As shown, the cooling assembly 100 also includes two first sealing rings 70 and two second sealing rings 80. The two first sealing rings 70 are respectively located between the first liquid suction port 201 of the first liquid pump 20 and the kettle body 1, and between the second liquid suction port 601 of the second liquid pump 60 and the kettle body 1, so as to fill the gap between the first liquid suction port 201 and the kettle body 1, and the gap between the second liquid suction port 601 and the kettle body 1, so as to prevent the cooling liquid in the first liquid outlet cavity 112 and the second liquid outlet cavity 172 from leaking. The two second sealing rings 80 are respectively located between the shell of the first liquid pump 20 and the kettle body 1, and between the shell of the second liquid pump 60 and the kettle body 1, to fill the gap between the shell of the first liquid pump 20 and the kettle body 1, and the gap between the shell of the second liquid pump 60 and the kettle body 1, to prevent the coolant flowing from the first drain port to the first adapter port 14 from leaking from the gap between the shell of the first liquid pump 20 and the kettle body 1, and to prevent the coolant flowing from the second drain port 602 to the second adapter port 101 from leaking from the gap between the shell of the second liquid pump 60 and the kettle body 1.

[0100] In some embodiments of the present invention, the first adapter 14 can be connected to the first radiator through a pipeline, the first liquid inlet 12 can be connected to the first heating element through a pipeline, the second adapter 101 can be connected to the second radiator through a pipeline, and the second liquid inlet 18 can be connected to the second heating element through a pipeline. The first adapter 14, the first liquid inlet 12, the second adapter 101 and the second liquid inlet 18 can all adopt VDA (Verband der Automobilindustrie, German Association of the Automotive Industry) standard quick connectors, which can improve the sealing reliability while improving the convenience of installation, thereby helping to improve the installation efficiency of the cooling assembly 100.

[0101] In some embodiments of the present invention, the diameter of the first liquid inlet 12 is equal to the diameter of the first adapter 14, and the diameter of the second liquid inlet 18 is equal to the diameter of the second adapter 101, which is beneficial to reducing the adaptation requirements of the cooling component 100 to pipes of different diameters, and can reduce the flow resistance of the coolant, and the flow of the coolant in and out of the liquid storage pot 10 is more uniform.

[0102] In some embodiments of the present invention, referring to Figure 2 and Figure 8 As shown, in the upper and lower directions, the first liquid pump 20 and the second liquid pump 60 can be vertically installed on the pot body 1 of the liquid storage pot 10 by a plurality of fastening screws 90, and the openings of the first liquid suction port 201 of the first liquid pump 20 and the second liquid suction port 601 of the second liquid pump 60 are facing upward. As long as there is no shortage of coolant in the first liquid storage chamber 11 and the second liquid storage chamber 17, the first liquid pump 20 and the second liquid pump 60 can pump the coolant into the pipeline of the vehicle's cooling system, which can solve the problem of dry-running protection caused by the first liquid pump 20 and the second liquid pump 60 being arranged separately from the liquid storage pot 10, resulting in the first liquid pump 20 and the second liquid pump 60 needing to be connected to the liquid storage pot 10 through a longer pipeline, and the first liquid pump 20 and the second liquid pump 60 cannot absorb coolant due to the long pipeline.

[0103] In some embodiments of the present invention, referring to Figure 2 As shown, the kettle body 1 can be welded by an upper shell 1a and a lower shell 1b. When manufacturing the kettle body 1, the upper shell 1a and the lower shell 1b can be manufactured separately, which is beneficial to reducing the difficulty of manufacturing the kettle body 1.
