[0040] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0041] Reference below Figure 1-Figure 7 An integrated water pump assembly and a vehicle thermal management system according to embodiments of the present application are described.

[0042] The present application embodiment provides an integrated water pump 200 assembly, such as Figure 1-Figure 5 As shown, the integrated water pump assembly includes a housing 100 , a valve core 300 and a water pump 200 .

[0043] Among them, Figure 3 and Figure 5 As shown, the shell 100 defines a valve cavity and a plurality of water channels connected to the valve cavity. The middle portion of the lower end surface of the shell 100 is recessed inwardly, and the recessed portion of the lower end surface of the shell 100 forms the valve cavity. The bottom wall of the valve cavity can serve as a valve seat.

[0044] like Figure 3 As shown, the valve core 300 is installed in the valve cavity, one end of the valve core 300 is connected to the bottom wall of the valve cavity, and the other end of the valve core 300 can extend to the outside of the valve cavity along its own axial direction.

[0045] The number of valve passages may be the same as the number of water channels. For example, when there are three water channels, the valve core 300 may be a three-way valve core 300; when there are four water channels, the valve core 300 may be a four-way valve core 300.

[0046] like Figure 3 and Figure 5As shown, the valve core 300 is connected to multiple water channels and is used to adjust the connection relationship between the multiple water channels. For example, the valve core 300 can change two originally connected water channels into two water channels respectively connected to another two water channels.

[0047] like Figure 1-Figure 5 As shown, the integrated water pump assembly further includes a water pump bracket 240 , which is mounted on the water pump 200 , and the water pump bracket 240 has a mounting position, and the water pump 200 can be installed to a designated position through the mounting position of the water pump bracket 240 .

[0048] like Figure 1-Figure 5 As shown, the water pump 200 is connected to the housing 100 , and the water pump 200 and the housing 100 may be connected by bolts, screws, snaps or other means to prevent the water pump 200 from being separated from the housing 100 .

[0049] like Figure 1-Figure 5 As shown, one of the water outlets of the water pump 200 is connected to the corresponding water channel. The water pump 200 may be provided with two water outlets, one of which is directly connected to a corresponding water channel. The water pump 200 may also be provided with other numbers of water outlets.

[0050] The direction in which the coolant flows in the water pump 200 is determined according to the direction of rotation of the water pump 200. For example, when the water pump 200 rotates forward, the coolant can enter the water pump 200 from the first water inlet of the water pump 200 and be discharged from the second water inlet; when the water pump 200 rotates reversely, the coolant can enter the water pump 200 from the second water inlet of the water pump 200 and be discharged from the first water inlet.

[0051] During the actual implementation process, one end of multiple water channels are connected to the valve cavity, the other end of the water channel corresponding to the first water outlet of the water pump 200 is connected to the first water outlet of the water pump 200, and the other ends of the remaining water channels are connected to other devices in the vehicle through pipes, that is, the first water outlet of the water pump 200 and the valve cavity are directly connected to the water channel of the shell 100, and the valve core 300 is used to adjust the connectivity of the multiple water channels according to actual conditions.

[0052] By providing a valve cavity and a plurality of water channels on the housing 100, and installing the water pump 200 on the housing 100, the valve core 300 and the water pump 200 can be directly connected through the water channels on the housing 100, that is, no pipeline is provided between the valve core 300 and the water inlet of the water pump 200, so that the valve core 300 and the water pump 200 are integrated into one through the housing 100, reducing the number of pipelines and parts, reducing the overall volume after the water pump 200 is connected to the valve core 300, reducing production costs, and facilitating assembly.

[0053] According to the integrated water pump assembly provided in the embodiment of the present application, by defining a valve cavity and a plurality of water channels connected to the valve cavity on the housing 100, the valve core 300 and the water pump 200 can be directly connected through the water channels on the housing 100, and no pipeline is set between the two. This can reduce the number of pipelines and parts, reduce the overall volume of the water pump 200 after being connected to the valve core 300, reduce production costs, and facilitate assembly. At the same time, the reduction in the number of pipelines and parts can reduce the number of seals, thereby reducing the sealing cost while ensuring the sealing effect.

[0054] In some embodiments, Figure 3 and Figure 5 As shown, the housing 100 is provided with a groove 160 communicated with the water channel, and one end of the water pump 200 close to the valve core 300 is installed in the groove 160 .

[0055] Among them, Figure 3 and Figure 5 As shown, the side of the housing 100 close to the water pump 200 has a groove 160 that is recessed inward relative to the side of the housing 100, and the bottom wall of the groove 160 is provided with a channel opening connected to the corresponding water channel, that is, the groove 160 is connected to the valve cavity through the water channel.

[0056] like Figure 3 and Figure 5 As shown, the water pump 200 has one end of a water outlet for communicating with the waterway, which is plugged into the groove 160, and the side wall of the groove 160 is connected to the outer wall of the water pump 200 by bolts, screws, snaps or other means. The water outlet of the water pump 200 is inserted into the channel opening of the groove 160 so that the water outlet can be connected to the waterway.

[0057] By installing the end of the water pump 200 in the groove 160 of the housing 100, the water pump 200 and the housing 100 can be integrated into one body while reducing the volume of the housing 100, thereby reducing the production cost to a certain extent.

[0058] In some embodiments, Figure 3 and Figure 5 As shown, the integrated water pump assembly further includes a second sealing member 230 , which is installed between the outer peripheral wall of the water inlet and the inner wall surface of the housing 100 .

[0059] Among them, Figure 3 and Figure 5 As shown, the second seal 230 is installed between the outer peripheral wall of the water outlet of the water pump 200 and the inner wall surface of the channel opening of the shell 100, that is, the second seal 230 is arranged at the connection between the water outlet and the water channel corresponding to the water outlet to avoid accidents caused by leakage of coolant from the connection between the water outlet and the water channel.

[0060] In some embodiments, the integrated water pump assembly further includes a first seal installed between the inner wall surface of the groove 160 and the outer wall surface of the water pump 200 .

[0061] Among them, the first seal is installed between the inner wall surface of the end of the groove 160 away from the valve core 300 and the outer wall surface of the water pump 200, that is, the first seal is arranged at the connection between the water pump 200 and the housing 100, which can prevent the coolant from leaking from the connection between the water pump 200 and the housing 100 when the second seal 230 fails, thereby providing double sealing for the integrated water pump assembly and further improving the safety of the integrated water pump assembly.

[0062] In some embodiments, Figure 3 and Figure 5 As shown, the shell 100 defines the first to fourth water channels 140, and the valve core 300 is a four-way valve core 300 for adjusting the connectivity status of the first to fourth water channels 140; the water pump 200 includes a first water pump 200 and a second water pump 200, one of the water outlets of the first water pump 200 is connected to the second water channel 120, and one of the water outlets of the second water pump 200 is connected to the fourth water channel 140.

[0063] Among them, Figure 3 and Figure 5 As shown, the first water channel 110, the second water channel 120, the third water channel 130 and the fourth water channel 140 can be set as water channels in the same plane, or the relative position relationship of the first water channel 110, the second water channel 120, the third water channel 130 and the fourth water channel 140 can be set according to the actual connection between each water channel and other heating equipment.

[0064] like Figure 3 and Figure 5 As shown, the first water channel 110, the second water channel 120, the third water channel 130 and the fourth water channel 140 can be evenly spaced apart along the circumference, or can be unevenly spaced apart along the circumference or arranged in other ways. For example, as shown in the figure, the first water channel 110, the second water channel 120, the third water channel 130 and the fourth water channel 140 are evenly spaced apart along the circumference, which can provide a larger space for the connection between each water channel and other heating equipment.

[0065] like Figure 3 and Figure 5As shown, the valve core 300 can be a four-way valve core 300 that adjusts the connectivity of the first water channel 110, the second water channel 120, the third water channel 130 and the fourth water channel 140 by rotating around a pivot axis. The valve core 300 has a first connecting hole 310 and a second connecting hole 320 that are arranged opposite to each other. The first connecting hole 310 can connect two water channels among the first water channel 110, the second water channel 120, the third water channel 130 and the fourth water channel 140, and the second connecting hole 320 can connect the other two water channels among the first water channel 110, the second water channel 120, the third water channel 130 and the fourth water channel 140.

[0066] The first water channel 110 and the third water channel 130 are used to form a first water channel outlet 111 and a third water channel outlet 131 respectively with one end of a cooling loop of other heat generating equipment.

[0067] like Figure 1-Figure 5 As shown, the first water pump 210 may have a first water inlet 211 and a first water outlet 212 , the first water inlet 211 may be connected to the corresponding second water channel 120 , and the first water outlet 212 may be connected to other heating devices in the vehicle.

[0068] like Figure 1-Figure 5 As shown, the second water pump 220 may have a second water inlet 221 and a second water outlet 222 , the second water inlet 221 may be connected to the corresponding fourth water channel 140 , and the second water outlet 222 may be connected to other heating devices in the vehicle.

[0069] The four-way valve core 300 has two working states during operation. When the four-way valve core 300 is in the first working state, one of the first connecting hole 310 and the second connecting hole 320 is respectively connected to the second water channel 120 and the third water channel 130, that is, one of the first connecting hole 310 and the second connecting hole 320 connects the second water channel 120 and the third water channel 130; the other of the first connecting hole 310 and the second connecting hole 320 is respectively connected to the first water channel 110 and the fourth water channel 140, that is, the other of the first connecting hole 310 and the second connecting hole 320 connects the first water channel 110 and the fourth water channel 140.

[0070] When the four-way valve core 300 is in the second working state, one of the first connecting hole 310 and the second connecting hole 320 is respectively connected to the first water channel 110 and the second water channel 120, that is, one of the first connecting hole 310 and the second connecting hole 320 connects the first water channel 110 and the second water channel 120; the other of the first connecting hole 310 and the second connecting hole 320 is respectively connected to the third water channel 130 and the fourth water channel 140, that is, the other of the first connecting hole 310 and the second connecting hole 320 connects the third water channel 130 and the fourth water channel 140.

[0071] During the actual implementation process, the first water inlet 211 of the first water pump 210 is connected to the second water channel 120 of the shell 100, the second water inlet 221 of the second water pump 220 is connected to the fourth water channel 140 of the shell 100, and the first water outlet 212 of the first water pump 210, the second water outlet 222 of the second water pump 220, the first water channel 110 and the third water channel 130 of the shell 100 are all connected to other heating devices of the vehicle.

[0072] When the four-way valve core 300 is in the first working state, the second water channel 120 and the third water channel 130 can be connected through the first connecting hole 310, and the first water channel 110 and the fourth water channel 140 can be connected through the second connecting hole 320. The flow direction of the first coolant flow path can be that the coolant flows into the first water channel 110, flows into the fourth water channel 140 after passing through the second connecting hole 320, and flows out of the first water pump 210 after passing through the first water inlet 211 and the first water outlet 212 of the first water pump 210 in sequence. The flow direction of the second coolant flow path can be that the coolant flows into the third water channel 130, flows into the second water channel 120 after passing through the first connecting hole 310, and flows out of the second water pump 220 after passing through the second water inlet 221 and the second water outlet 222 of the second water pump 220 in sequence.

[0073] When the four-way valve core 300 needs to be switched from the first working state to the second working state, the four-way valve core 300 is controlled to rotate around its pivot axis until the four-way valve core 300 is connected to the first water channel 110 and the second water channel 120, and the third water channel 130 and the fourth water channel 140 are connected at the same time. For example, the first water channel 110 and the second water channel 120 can be connected through the first connecting hole 310, and the third water channel 130 and the fourth water channel 140 can be connected through the second connecting hole 320. At this time, the first coolant flow The flow direction of the first cooling liquid flow path can be that the coolant flows into the third water channel 130, flows into the fourth water channel 140 after passing through the second connecting hole 320, and flows out after passing through the first water inlet 211 and the first water outlet 212 of the first water pump 210 in sequence. The flow direction of the second cooling liquid flow path can be that the coolant flows into the third water channel 130, flows into the second water channel 120 after passing through the first connecting hole 310, and flows out of the second water pump 220 after passing through the second water inlet 221 and the second water outlet 222 of the second water pump 220 in sequence.

[0074] By setting the above-mentioned first water channel 110, second water channel 120, third water channel 130, fourth water channel 140, four-way valve core 300, first water pump 210 and second water pump 220, switching between the two coolant flow paths can be achieved, and each water channel, four-way valve core 300 and water pump 200 are integrated into one, with a simple structure and a simple switching method.

[0075] In other embodiments, Figure 3 and Figure 5As shown, the integrated water pump assembly may further include a third sealing member 330 , which is installed between the outer wall surface of one end of the valve core 300 close to the water channel and the inner wall surface of the valve cavity.

[0076] Among them, Figure 3 and Figure 5 As shown, a third sealing member 330 is provided between the outer wall surfaces at both ends of the first connecting hole 310 and the inner wall surface of the valve cavity, and between the outer wall surfaces at both ends of the second connecting hole 320 and the inner wall surface of the valve cavity, so as to prevent the coolant from leaking from between the first connecting hole 310 and the water channel, and between the second connecting hole 320 and the water channel, thereby further improving the sealing and safety of the integrated water pump assembly.

[0077] In some embodiments, Figure 3 As shown, the housing 100 further defines a water outlet channel 150 , one end of which is connected to at least one of the second water channel 120 and the fourth water channel 140 , and the other end of the water outlet channel 150 forms a water outlet 151 of the integrated water pump 200 assembly.

[0078] Among them, Figure 3 As shown, at least one of the second water channel 120 and the fourth water channel 140 is provided with a connecting port 141. For example, as shown in the figure, the fourth water channel 140 is provided with a connecting port 141. The fourth water channel 140 is connected to one end of the water outlet channel 150 through the connecting port 141. The other end of the water outlet channel 150 forms a water diversion port 151 of the integrated water pump assembly, and the water diversion port 151 can be connected to the coolant storage device 400.

[0079] During the actual implementation process, when the water pump 200 corresponding to the water outlet channel 150 is in a throttling working state, the coolant flow entering the water pump 200 is reduced, but the coolant flow entering the valve core 300 and the water channel from the first water channel 110 and the third water channel 130 remains unchanged. Since the water channel corresponding to the water pump 200 is connected to the water outlet channel 150, part of the coolant in the water channel can flow back to the coolant storage device 400 through the water outlet channel 150.

[0080] By setting the water outlet channel 150, part of the coolant in the water channel corresponding to the water pump 200 can be discharged from the water outlet channel 150 to the coolant storage device 400 when the water pump 200 is in a throttling working state, thereby avoiding excessive flow in the water channel and the valve core 300, which may cause the coolant flow rate in the heating device connected to the first water channel 110 and the third water channel 130 to be too slow, thereby ensuring the circulation of the coolant and the cooling effect.

[0081] In some embodiments, Figure 3As shown, the outlet channel 150 extends along the first direction, one end of the outlet channel 150 is connected to one of the second water channel 120 and the fourth water channel 140 , and the other end of the outlet channel 150 extends to the position of the other of the second water channel 120 and the fourth water channel 140 .

[0082] Among them, Figure 3 As shown, the first direction can be the length direction of the shell 100, and the water outlet channel 150 is connected to one of the second water channel 120 and the fourth water channel 140. For example, one end of the water outlet channel 150 is connected to the fourth water channel 140, and the other end of the water outlet channel 150 extends along the axial direction of the water pump 200 to the position of the fourth water channel 140, that is, the water diversion port 151 is located at the position of the fourth water channel 140, and the connecting port 141 is located at the lower side of the water outlet channel 150, and the water diversion port 151 is located on the upper side of the water outlet channel 150.

[0083] During the actual implementation process, when the water pump 200 corresponding to the water outlet channel 150 is in a throttling working state, part of the coolant in the water channel corresponding to the water pump 200 is discharged from the connecting port 141 into the water outlet channel 150. Since the water diversion port 151 and the connecting port 141 have a certain height difference, the coolant will not be immediately discharged into the coolant storage device 400 after entering the water outlet channel 150 from the connecting port 141, but will be stored in the water outlet channel 150. When the height of the coolant in the water outlet channel 150 reaches the height of the water diversion port 151, the coolant in the water outlet channel 150 begins to be discharged to the coolant storage device 400.

[0084] When the water pump 200 corresponding to the water outlet channel 150 switches from the throttling working state to the normal working state, the flow of coolant entering the water pump 200 increases. If the flow of coolant entering the valve core 300 is small, the water pump 200 can extract part of the coolant in the water outlet channel 150 for replenishment.

[0085] By setting the water outlet channel 150 to extend along the length direction of the shell 100, the space of the water outlet channel 150 can be increased without increasing the overall occupied space. At the same time, the water diversion port 151 and the connecting port 141 are set to have a certain height difference, so that part of the coolant can be stored when the water pump 200 is in the throttling working state. When the water pump 200 switches back to the normal working state, the coolant originally stored in the water outlet channel 150 can be used to replenish it in time, ensuring that sufficient coolant participates in the cooling cycle.

[0086] In some embodiments, Figure 3 and Figure 5 As shown, the first water channel 110 and the third water channel 130 are disposed at both ends of the housing 100 along the second direction; the second water channel 120 and the fourth water channel 140 are disposed at both ends of the housing 100 along the first direction.

[0087] Among them, Figure 3 and Figure 5 As shown, the first direction can be the length direction of the shell 100, and the second direction can be the width direction of the shell 100. The first water channel 110 and the third water channel 130 are respectively arranged at the two ends of the shell 100 in the width direction, and the second water channel 120 and the fourth water channel 140 are respectively arranged at the two ends of the length direction of the shell 100, that is, the first water channel 110, the second water channel 120, the third water channel 130 and the fourth water channel 140 are evenly spaced and distributed along the circumference of the valve core 300, and the angle between two adjacent water channels is 90°.

[0088] like Figure 3 and Figure 5 As shown, the fourth water channel 140 and the second water channel 120 are connected to the first water pump 210 and the second water pump 220 respectively. At this time, the valve core 300 only needs to rotate 90° to switch from the first working state to the second working state.

[0089] By arranging the first water channel 110 and the third water channel 130 at both ends of the shell 100 along the second direction, and arranging the second water channel 120 and the fourth water channel 140 at both ends of the shell 100 along the first direction, the rotation angle of the valve core 300 when switching from the first working state to the second working state can be reduced, thereby improving the conversion efficiency between the two coolant flow paths.

[0090] In some embodiments, Figure 1-Figure 5 As shown, another water inlet of the first water pump 200 and another water inlet of the second water pump 200 extend toward both ends of the second direction respectively, and another water inlet of the first water pump 200 is spaced apart from the first water channel 110 along the first direction, and another water inlet of the second water pump 200 is spaced apart from the third water channel 130 along the first direction.

[0091] Among them, Figure 1-Figure 5 As shown, the first water outlet 212 of the first water pump 210 and the second water outlet 222 of the second water pump 220 extend toward both ends of the width direction of the shell 100 respectively, and the first water outlet 212 of the first water pump 210 and the first water channel 110 are arranged spaced apart along the length direction of the shell 100, and the second water outlet 222 of the second water pump 220 and the third water channel 130 are arranged spaced apart along the length direction of the shell 100.

[0092] By arranging the first water outlet 212 of the first water pump 210 and the first water channel 110 apart from each other along the length direction of the shell 100, and arranging the second water outlet 222 of the second water pump 220 and the third water channel 130 apart from each other along the length direction of the shell 100, the pipes connected to the first water outlet 212, the second water outlet 222, the third water channel 130 and the first water channel 110 can be concentrated and arranged along the length direction of the shell 100, thereby improving the neatness of the pipeline layout.

[0093] An embodiment of the present application also provides a vehicle thermal management system, which is applied to a vehicle. The vehicle thermal management system includes an integrated water pump assembly as described in any of the above embodiments, a cooling circuit of a heating device, a coolant storage device 400 and a radiator 500, wherein the cooling circuit of the heating device, the coolant storage device 400 and the radiator 500 are respectively connected to a water channel and another water outlet of the water pump 200.

[0094] Among them, the heat generating device may be a charger 600, a battery or other device, the cooling circuit and the radiator 500 of the heat generating device may be connected to the first water outlet 212 of the first water pump 210 and the second water outlet 222 of the second water pump 220 respectively, and the first water channel 110 and the third water channel 130 of the shell 100 may be connected to the coolant storage device 400.

[0095] The following is a specific description using the charger 600 as an example.

[0096] like Figure 6 As shown, when the four-way valve core 300 is in the first working state, the first coolant flow path can be that the coolant enters the valve core 300 from the coolant storage device 400 through the first water channel 110, and enters the fourth water channel 140 through the valve core 300, enters the first water pump 210 from the fourth water channel 140 through the first water inlet 211 of the first water pump 210, and is finally discharged from the first water outlet 212 of the first water pump 210 to the cooling circuit of the charger 600; the second coolant flow path can be that the coolant enters the valve core 300 from the coolant storage device 400 through the third water channel 130, and enters the second water channel 120 through the valve core 300, enters the second water pump 220 from the second water channel 120 through the second water inlet 221 of the second water pump 220, and is finally discharged from the second water outlet 222 of the second water pump 220 to the radiator 500.

[0097] like Figure 7As shown, when the four-way valve core 300 is in the second working state, the first cooling liquid flow path can be that the coolant enters the valve core 300 from the coolant storage device 400 through the third water channel 130, and enters the fourth water channel 140 through the valve core 300, and enters the first water pump 210 from the fourth water channel 140 through the first water inlet 211 of the first water pump 210, and finally is discharged from the first water outlet 212 of the first water pump 210 to the cooling circuit of the charger 600; the second cooling liquid flow path can be that the coolant enters the valve core 300 from the coolant storage device 400 through the first water channel 110, and enters the second water channel 120 through the valve core 300, and enters the second water channel 120 through the second water inlet 221 of the second water pump 220 from the second water channel 120 to the second water pump 220, and finally is discharged from the second water outlet 222 of the second water pump 220 to the radiator 500.

[0098] According to the vehicle thermal management system provided in the embodiments of the present application, by adopting the integrated water pump assembly of any of the above-mentioned embodiments, the valve core 300 and the water pump 200 can be directly connected through the water channel on the housing 100, and no pipeline is set between the two. This can reduce the number of pipelines and components, reduce the overall volume of the water pump 200 after connecting with the valve core 300, reduce production costs, and facilitate assembly. At the same time, the reduction in the number of pipelines and components can reduce the number of seals, thereby reducing the sealing cost while ensuring the sealing effect.
