For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements.

[0033] The embodiments of this application provide a cooler, which is used for heat transfer connection with a heating module. The temperature of the cooler is relatively low and can absorb the heat released by the heating module to achieve the cooling of the heating module. There can be various types of heating modules. Exemplarily, in some embodiments of this application, the heating module may include at least one of a motor, a motor controller, a battery, an intelligent driving domain controller, an intercooler, an on-vehicle charger, and a water-cooled plate heat exchanger, etc.
[0034] Please refer to Figure 1 , Figure 2 and Figure 3 , the embodiments of this application provide a cooler (refer to the second cooler 43 in the figure). The cooler has an inlet (refer to the second inlet 432 in the figure) and an outlet (refer to the second outlet 431 in the figure). The inlet is adapted to communicate with the outlet 4421 of the liquid storage container 44, and the outlet is adapted to communicate with the inlet 4411 of the liquid storage container 44, so that the cooler and the liquid storage container 44 form a loop; along the gravity direction g, the liquid level of the coolant in the cooler is higher than the highest liquid level of the coolant in the liquid storage container 44, and the outlet is located at the highest liquid level of the coolant in the cooler.
[0035] In the cooler provided by the present application, the drain port is located at the highest liquid level of the coolant inside the cooler. The position of the drain port is relatively high. When the liquid pump 1 in the cooling system stops, due to the action of gravity, it is not easy for the coolant inside the cooler to drain out through the drain port. That is, when the liquid pump 1 stops, the coolant can be well retained inside the cooler and is not likely to flow into the liquid storage container 44, affecting the liquid level of the coolant in the liquid storage container 44 and making it not easy for the coolant to overflow from the liquid storage container 44, which is beneficial to improving the safety of the vehicle cooling system.
[0036] Moreover, since it is not easy for the coolant to overflow from the liquid storage container 44, a relatively large amount of coolant is retained in the entire circuit, which is beneficial to improving the cooling efficiency.
[0037] In addition, when the liquid pump 1 stops, a relatively large amount of coolant is retained in the cooler, resulting in less air accumulation in the cooler, which is beneficial to reducing the cavitation phenomenon in the cooler and also beneficial to improving the cooling efficiency of the cooler.
[0038] Please refer to Figure 1 、 Figure 2 and Figure 3 It can be understood that in the embodiments of the present application, the cooler is connected in series with the liquid storage container 44. After the coolant in the liquid storage container 44 is discharged from the liquid outlet 4421, it enters the cooler through the liquid inlet. It absorbs the heat of the heat generating module inside the cooler, and after absorbing the heat, it is discharged from the cooler through the drain port and returns to the liquid storage container 44 again through the liquid inlet 4411 to achieve circulation. During the whole process, the liquid pump 1 provides power for the flow of the coolant. It can be understood that the temperature of the coolant increases after absorbing heat. When it is discharged from the cooler through the drain port, it can take away the heat of the heat generating module and create space for the coolant upstream of the cooler, enabling the cooler upstream with a lower temperature to smoothly enter the cooler through the liquid inlet and continuously absorb the heat of the heat generating module.
[0039] Please refer to Figure 1 、 Figure 2 and Figure 3 In some embodiments of the present application, the cooler, the liquid storage container 44 and the radiator 5 may be connected in series to form a circuit. Exemplarily, in some embodiments of the present application, the radiator 5 is connected in series between the liquid outlet 4421 and the liquid inlet. That is, the radiator 5 has a heat dissipation inlet 51 and a heat dissipation outlet 52. The heat dissipation inlet 51 is communicated with the liquid outlet 4421, and the heat dissipation outlet 52 is communicated with the liquid inlet. That is, the coolant discharged from the liquid storage container 44 through the liquid outlet 4421 can enter the radiator 5 through the heat dissipation inlet 51 for cooling. After cooling, the coolant with a lower temperature is discharged from the radiator 5 through the heat dissipation outlet 52 and enters the cooler through the liquid inlet to absorb the heat of the heat generating module.
[0040] Please refer to Figure 1 、 Figure 2 and Figure 3 In the embodiments of the present application, for the highest liquid level of the coolant in the liquid storage container 44, please refer to Figure 3 the first liquid level a therein, and for the highest liquid level of the coolant in the cooler, please refer to Figure 3 the second liquid level b therein. The second liquid level b is higher than the first liquid level a. Such that when the liquid pump 1 stops, due to the action of gravity, there is a risk that the part of the coolant in the cooler above the first liquid level a will fall into the liquid storage container 44, resulting in unstable liquid level of the coolant in the liquid storage container 44. In the present application, the drain port is located at the highest liquid level of the coolant in the cooler. The position of the drain port is relatively high. When the liquid pump 1 of the cooling system stops, due to the action of gravity, it is not easy for the coolant in the cooler to be discharged from the drain port, which is beneficial to stabilizing the liquid level of the coolant in the liquid storage container 44. Therefore, by setting the drain port at the highest liquid level of the coolant in the cooler, the cooler in the present application can be arranged at a relatively high position, with greater position flexibility, making the layout of the cooler more convenient.
[0041] Please refer to Figure 1 、 Figure 2 and Figure 3 It should be noted that in the embodiments of the present application, the liquid inlet 4411 and the liquid outlet 4421 are two different openings of the liquid storage container 44.
[0042] Please refer to Figure 1 、 Figure 2 and Figure 3 In the embodiments of the present application, there can be various types of coolant, for example, it can be water, alcohol, glycerol-based coolant, ethylene glycol type, propylene glycol, or a mixture including the above components, etc. In some embodiments of the present application, the coolant is water, and the liquid storage container 44 can be a water tank or a secondary water tank, etc.
[0043] Please refer to Figure 1 、 Figure 2 and Figure 3 In some embodiments of the present application, the drain port is formed on the upper side surface of the cooler. In this way, the position of the drain port is relatively high. When the liquid pump 1 stops, it is not easy for the coolant to be discharged from the drain port, which is beneficial to improving the cooling efficiency and safety.
[0044] Please refer to Figure 1 、 Figure 2 and Figure 3, in some embodiments of the present application, the liquid inlet is located at the lower end of the cooler in the direction of gravity g. In such a structural form, the coolant can fully fill the cooling cavity. It can be understood that the mass of the coolant is greater than that of air. Making the liquid inlet located at the lower end of the cooler enables the coolant to fully fill the interior of the cooler, which is beneficial to improving the cooling effect of the cooler and reducing the accumulation of air in the cooler, thereby helping to reduce the cavitation phenomenon in the cooler.
[0045] Please refer to Figure 1 、 Figure 2 and Figure 3 , in some embodiments of the present application, the liquid inlet is formed on the lower side surface of the cooler. In such a structural form, the position of the inlet is relatively low, enabling the coolant to fully fill the interior of the cooler, which is beneficial to improving the cooling effect of the cooler and reducing the accumulation of air in the cooler, thereby helping to reduce the cavitation phenomenon in the cooler.
[0046] Please refer to Figure 1 、 Figure 2 and Figure 3 , in some embodiments of the present application, the cooler further includes a first one-way valve, and the first one-way valve is arranged at the liquid inlet and conducts from outside the cooler to inside the cooler. In such a structural form, when the liquid pump 1 stops operating, the coolant in the cooling cavity is not easily reversed through the liquid inlet into the liquid storage container 44, which is beneficial to improving the cooling efficiency and the safety of the vehicle cooling system.
[0047] Please refer to Figure 1 、 Figure 2 and Figure 4 , the present application also provides a cooling system, which includes a liquid pump 1, a first cooling branch 3 and a second cooling branch 4. The first cooling branch 3 is adapted to be heat-transfer connected to the first heat-generating module, and the first cooling branch 3 and the liquid pump 1 form a loop; the second cooling branch 4 is adapted to be heat-transfer connected to the second heat-generating module; the second cooling branch 4 is in parallel with the first cooling branch 3; the second cooling branch 4 includes a liquid storage container 44, and the liquid storage container 44 includes a liquid inlet 4411 and a liquid outlet 4421, and both the liquid inlet 4411 and the liquid outlet 4421 are communicated with the liquid pump 1 to form a loop between the liquid storage container 44 and the liquid pump 1.
[0048] Please refer to Figure 1 、 Figure 2 and Figure 4, in the vehicle cooling system provided by the embodiment of the present application, the first cooling branch 3 and the liquid pump 1 form a loop, which is hereinafter referred to as the first loop for short. The second cooling branch 4 and the liquid pump 1 form a loop, which is hereinafter referred to as the second loop for short. The liquid storage container 44 is a part of the second loop. The coolant discharged from the outlet 12 of the liquid pump 1 can enter the liquid storage container 44 through the liquid inlet 4411, and the coolant discharged from the liquid storage container 44 through the liquid outlet 4421 can return to the liquid pump 1 through the inlet 11 of the liquid pump 1, realizing the circulating flow of the coolant. The liquid storage container 44 is connected in parallel with the first cooling branch 3, so that the coolant discharged from the liquid storage container 44 through the liquid outlet 4421 can flow into the second loop and participate in the circulation of the coolant in the second cooling loop, achieving the effect of supplementing the coolant to the second loop. Therefore, in the vehicle cooling system provided by the present application, the liquid storage container 44 can supply coolant to both types of cooling loops, namely the first loop and the second loop, the liquid storage container 44 can be fully utilized, the system efficiency is relatively high, and the number of liquid storage containers 44 required for the vehicle cooling system is small, which is beneficial to reducing costs.
[0049] Please refer to Figure 1 , Figure 2 and Figure 4 , moreover, in the embodiment of the present application, the liquid pump 1 can not only drive the coolant in the first cooling branch 3 to flow, but also drive the coolant in the second cooling branch 4 to flow. The liquid pump 1 can be fully utilized, the system efficiency is relatively high, and the number of liquid pumps 1 required for the vehicle cooling system is small, which is beneficial to reducing costs.
[0050] Please refer to Figure 1 , Figure 2 and Figure 4 , in the embodiment of the present application, the first cooling branch 3 includes a first inlet 311 and a first outlet 12. The first cooling branch 3 and the liquid pump 1 jointly form a loop, that is, the coolant discharged from the outlet 12 of the liquid pump 1 enters the first cooling branch 3 through the first inlet 311, and under the guidance of the first cooling branch 3, flows to the first discharge port 321, is discharged from the first cooling branch 3 through the first discharge port 321, and then returns to the liquid pump 1 through the inlet 11, realizing the circulating flow of the coolant.
[0051] Please refer to Figure 1 , Figure 2 and Figure 4 , it can be understood that in the embodiment of the present application, the second cooling branch 4 is connected in parallel with the first cooling branch 3, that is, the coolant discharged from the outlet 12 of the liquid pump 1 is split into at least two paths. Among the at least two paths of coolant, one path enters the first cooling branch 3, and the other path enters the second cooling branch 4. The coolant discharged from the first cooling branch 3 and the second cooling branch 4 both return to the liquid pump 1 through the inlet 11, realizing the circulating flow.
[0052] Please refer to Figure 1 、 Figure 2 and Figure 4 , in some embodiments of the present application, the cooling system may further include a manifold 9, which is connected in series between the inlet 11 and the first cooling branch 3, and is also connected in series between the inlet 11 and the second cooling branch 4. After the coolant discharged from the first cooling branch 3 and the second cooling branch 4 converges in the manifold 9, it enters the liquid pump 1 through the inlet 11. In some embodiments of the present application, the second cooling branch 4 includes a liquid outlet pipe 45, and the liquid outlet pipe 45 is connected in series between the liquid outlet 4421 and the manifold 9. In this way, it is convenient to arrange the manifold 9, the second cooling branch 4 and the liquid storage container 44.
[0053] Please refer to Figure 1 、 Figure 2 and Figure 4 , in some embodiments of the present application, the cooling system may further include an outlet pipe, which is connected in series between the outlet 12 and the first cooling branch 3, and is also connected in series between the outlet 12 and the second cooling branch 4. In this way, after the coolant is discharged from the outlet 12 of the liquid pump 1, it enters the outlet pipe, and then is divided into two paths and enters the first cooling branch 3 and the second cooling branch 4 respectively.
[0054] Please refer to Figure 1 、 Figure 2 and Figure 4 , the embodiments of the present application do not limit the number of the first cooling branch 3 and the second cooling branch 4, which may be one or at least two. When the first cooling branch 3 is at least two, the at least two first cooling branches 3 may be connected in parallel. When the second cooling branch 4 is at least two, the at least two second cooling branches 4 may be connected in parallel.
[0055] Please refer to Figure 1 、 Figure 2 and Figure 4 , in some embodiments of the present application, the first cooling branch 3 includes an exhaust port 331, and the liquid storage container 44 includes a gas collecting port 4412, and the exhaust port 331 is communicated with the gas collecting port 4412. In such a structural form, the accumulated gas in the first cooling branch 3 can be transported into the liquid storage container 44, and a relatively high gas removal rate can be achieved, which is beneficial to reducing the cavitation phenomenon in the first cooling branch 3 and also beneficial to improving the heat dissipation efficiency of the first cooling branch 3.
[0056] Please refer to Figure 1 、 Figure 2 and Figure 4 , in some embodiments of the present application, the exhaust port 331 is communicated with the gas collecting port 4412 through an exhaust pipe 6. In this way, the communication between the exhaust port 331 and the gas collecting port 4412 can be realized more conveniently.
[0057] Please refer toFigure 1 , Figure 2 and Figure 4 , it should be noted that in the embodiments of the present application, the liquid storage container 44 and the liquid pump 1 are connected in series to form a loop, so that the gas accumulated in the second cooling branch 4 can be smoothly transported into the liquid storage container 44 along with the coolant, achieving a certain degree of degassing, enabling the second cooling branch 4 to reduce or not provide an exhaust pipeline, which is beneficial to simplifying the pipeline structure and reducing costs.
[0058] Please refer to Figure 1 , Figure 2 and Figure 4 , in some embodiments of the present application, the first cooling branch 3 includes a first cooler 33, and the first cooler 33 is adapted to be heat-transfer connected to the first heat-generating module. In such a structural form, the coolant in the first cooler 33 can absorb the heat released by the first heat-generating module, flow out of the first cooler 33 after absorbing the heat, and can transfer the heat to the low-temperature area of the loop, taking away the heat of the first heat-generating module and achieving a cooling effect.
[0059] Please refer to Figure 1 , Figure 2 and Figure 4 , it should be noted that in the embodiments of the present application, the first cooler 33 has a first liquid inlet 333 and a second liquid discharge port 431. The first liquid inlet 333 is connected to the outlet 12 and can be connected through the first liquid inlet pipe 31. The first liquid discharge port 332 is connected between the liquid outlet 4421 and the inlet 11 and can be connected to the liquid outlet 4421 and the inlet 11 through the first liquid discharge pipe 32. After the coolant is discharged from the liquid pump 1 through the outlet 12, it enters the first cooler 33 through the first liquid inlet 333, absorbs the heat of the first heat-generating module, and then is discharged from the first cooler 33 through the first liquid discharge port 332 and returns to the liquid pump 1 again through the inlet 11 to achieve circulation.
[0060] Please refer to Figure 1 , Figure 2 and Figure 4 , in some embodiments of the present application, the exhaust port 331 is provided on the first cooler 33. In such a structural form, the accumulated gas in the first cooler 33 can be reduced, which is beneficial to improving the heat exchange efficiency of the first cooler 33 and also beneficial to reducing the cavitation phenomenon in the first cooler 33, thereby improving the reliability of the first cooler 33.
[0061] Please refer to Figure 1 , Figure 2 and Figure 4, in some embodiments of the present application, the exhaust port 331 is provided at the upper end of the inner cavity of the first cooler 33. It can be understood that the accumulated gas is lighter in mass and is likely to accumulate in large quantities at the upper end of the inner cavity of the first cooler 33. By arranging the exhaust port 331 at the upper end of the inner cavity of the first cooler 33, the accumulated gas can be smoothly discharged from the first cooler 33 through the exhaust port 331.
[0062] Please refer to Figure 1 , Figure 2 and Figure 4 , in some embodiments of the present application, both the first inflow port and the first drainage port are provided at the lower end of the inner cavity of the first cooler 33. In this way, a better gas-liquid separation effect can be achieved, enabling the accumulated gas to be smoothly discharged from the first cooler 33 through the exhaust port 331.
[0063] Please refer to Figure 1 , Figure 2 and Figure 4 , in some embodiments of the present application, the first heating module includes at least one of a motor, a motor controller, and a battery. The motor, the motor controller, and the battery require a relatively high cooling efficiency, and it is more appropriate to use the first cooling branch 3 with a relatively high degassing efficiency for cooling.
[0064] Please refer to Figure 1 , Figure 2 and Figure 4 , in some embodiments of the present application, the second cooling branch 4 further includes a second cooler 43, and the second cooler 43 is in heat transfer connection with the second heating module. In such a structural form, the coolant in the second cooler 43 can absorb the heat released by the second heating module, flow out of the second cooler 43 after absorbing the heat, and can transfer the heat to the low-temperature area of the loop, taking away the heat of the second heating module and achieving a cooling effect.
[0065] Please refer to Figure 1 , Figure 2 and Figure 4 , it should be explained that in the embodiments of the present application, the second cooler 43 has a second liquid inlet 432 and a second liquid drainage port 431. The second liquid inlet 432 is communicated with the outlet 12 and can be connected through the second liquid inlet pipe 41. The second liquid drainage port 431 is communicated with the liquid inlet 4411 and can be connected through the second liquid drainage pipe 42. The coolant is discharged from the liquid pump 1 through the outlet 12 and enters the second cooler 43 through the second liquid inlet 432, absorbs the heat of the second heating module, is discharged from the second cooler 43 through the second liquid drainage port 431, and enters the liquid storage container 44 through the liquid inlet 4411, and then returns to the liquid pump 1 through the liquid outlet 4421 and the inlet 11 in sequence to realize circulation.
[0066] Please refer to Figure 1 , Figure 2 andFigure 4 , in some embodiments of the present application, the second heating module includes an intercooler. Since the cooling efficiency of the intercooler is slightly lower, it is more appropriate to use the second cooling branch 4 for cooling, which is beneficial to cost savings.
[0067] Please refer to Figure 1 、 Figure 3 and Figure 4 , in some embodiments of the present application, along the gravity direction g, the liquid level of the coolant in the second cooler 43 is higher than the highest liquid level of the coolant in the liquid storage container 44, and the second drain port 431 is located at the highest liquid level of the coolant in the second cooler 43. In such a structural form, the position of the second drain port 431 is relatively high. When the liquid pump 1 of the cooling system stops, due to the action of gravity, the coolant in the second cooler 43 is not easily discharged from the second cooler 43 through the second drain port 431. That is, when the liquid pump 1 stops, the coolant can be better retained in the second cooler 43 and is not easily flowed into the liquid storage container 44, which affects the liquid level of the coolant in the liquid storage container 44 and makes the coolant not easily overflow from the liquid storage container 44, which is beneficial to improving the safety of the vehicle cooling system. Moreover, since the coolant is not easily overflowed from the liquid storage container 44, the amount of coolant retained in the entire circuit is relatively large, which is beneficial to improving the cooling efficiency. In addition, when the liquid pump 1 stops, more coolant is retained in the second cooler 43, so that less air is accumulated in the second cooler 43, which is beneficial to reducing the cavitation phenomenon in the second cooler 43 and also beneficial to improving the cooling efficiency of the cooler.

With such a structural form, in the case where the liquid pump 1 stops, the coolant in the second cooler 43 is not easily reversed through the second liquid inlet 432 into the liquid storage container 44, which is beneficial to improving the cooling efficiency and the safety of the vehicle cooling system.
