[0070] In the thermal management water pump assembly according to the present utility model, the pump shaft 170 is integrally formed with the flow channel plate 100, so that the water pump part can be integrated on the flow channel plate 100, without separately assembling the water pump and then assembling the water pump to the flow channel plate 100, thereby simplifying the assembly process and improving the assembly efficiency.

[0071] Further, the thermal management integration device further includes a pump housing 110, a stator 130, and a rotor 120. The pump housing 110 is disposed on the flow channel plate 100 and integrally formed with the flow channel plate 100. The stator 130 passes through the rotor 120 and is connected to the pump housing 110. The rotor 120 is disposed inside the pump housing 110. The rotor 120 is sleeved on the pump shaft 170, and the rotor 120 can rotate relative to the pump housing 110 under the electromagnetic action of the stator 130..

Compared with the scheme of integrally assembling the water pump to the flow channel plate 100, the structure is stable, and the assembly process of the water pump alone with the flow channel plate 100 is also avoided, thereby simplifying the assembly and improving the assembly efficiency. In addition, when the thermal management water pump assembly is damaged, the rotor 120 and the stator 130 can be disassembled and replaced respectively to complete the repair, without the need to replace the thermal management water pump assembly as a whole, reducing the repair cost.

[0073] Optionally, the pump shaft 170 is provided with a limiting member (not shown in the figure). The limiting member can be a convex ring formed on the pump shaft 170. The limiting member is located on the side of the rotor 120 away from the stator 130 along the axial direction of the pump shaft 170, and the limiting member abuts against the rotor 120. When the rotor 120 is installed in the pump housing 110, it abuts against the limiting member, so that the rotor 120 is limited by the stator 130 and the limiting member, enabling the rotor 120 to rotate stably relative to the pump shaft 170.

[0074] Optionally, referring to Figure 5 , the rotor 120 is provided with a receiving space at one end away from the flow channel plate 100. The stator 130 is at least partially disposed in the receiving space, and an air gap is provided between the stator 130 and the rotor 120. The receiving space formed by the rotor 120 enables the stator 130 to be at least partially disposed inside the rotor 120, so that the rotor 120 can rotate under the electromagnetic action of the stator 130.

[0075] Further, the rotor 120 includes a magnet 121 and an impeller 122. The impeller 122 is sleeved on the pump shaft 170.

An air gap is formed between the magnet 121 and the stator 130 in the circumferential direction, and an air gap is formed between the impeller 122 and the stator 130 in the axial direction D1. The structural arrangement of the rotor 120 enables the magnet 121 to be fully subjected to the electromagnetic action of the stator 130, and the impeller 122 rotates with the rotation of the magnet 121, and the impeller 122 will not be interfered by the magnetic field of the stator 130, with stable performance.

[0076] Referring to Figure 5, a first stepped groove 111 and a second stepped groove 112 are provided in the pump housing 110. The first stepped groove 111 and the second stepped groove 112 are arranged along the axial direction D1, and the inner diameter of the first stepped groove 111 is larger than the inner diameter of the second stepped groove 112. The magnet 121 is a permanent magnet 121, which is circular and tubular. The magnet 121 is arranged in the first stepped groove 111. The impeller 122 is arranged in the second stepped groove 112 and sleeved on the pump shaft 170. The impeller 122 is connected to the magnet 121. When the magnet 121 rotates under the electromagnetic action of the stator 130, the impeller 122 rotates with the rotation of the magnet 121, so as to apply pressure to the coolant in the pump housing 110.

[0077] Optionally, the magnet 121 and the impeller 122 can be integrally connected or assembled together by fasteners.

[0078] Optionally, a housing cover 131 is provided at one end of the stator 130 away from the flow channel plate 100. The housing cover 131 is detachably connected to the pump housing 110, so as to facilitate the installation of the stator 130 to the pump housing 110 and complete the installation work of the water pump part.

[0079] Furthermore, the stator 130 includes a stator coil 132 and a housing cover 131. The stator coil 132 passes through the magnet 121 and is sleeved on the end of the pump shaft 170. The housing cover 131 is fixedly connected to the stator coil 132, and the housing cover 131 is connected to the pump housing 110 by fasteners, so that the stator coil 132 is fixed relative to the pump housing 110. When the stator coil 132 is energized, a magnetic field is formed in the stator coil 132, and then the rotation of the magnet 121 can be controlled.

[0080] The present utility model also provides a thermal management integrated device, which includes the thermal management water pump assembly according to the above and a water valve 140.

[0081] Furthermore, referring to Figure 3 and Figure 4, the flow channel plate 100 includes a first plate 103 and a second plate 104. Along the axial direction D1 of the pump shaft 170, the first plate 103 and the second plate 104 are welded together, realizing the processing of the flow channel plate 100 and being suitable for integrating different module parts together.

During the actual water inlet process, the coolant enters the water inlet channel 105 through the water inlet 101, and then enters the pump housing 110 through the sunk groove 107 and the water inlet holes 106.

[0084] Refer to Figure 2 , the thermal management integration device according to the present utility model further includes a controller 160. The controller 160 is electrically connected to the stator coil 132.

The controller 160 is arranged in the sunk groove 107, the controller 160 is fixed to the first plate 103 by fasteners, and the controller 160 and the first plate 103 are hermetically connected together by a flange. The arrangement of the controller 160 and the first plate 103 enables the controller 160 to be cooled by the cooling liquid passing through the sunk groove 107, which is beneficial to the heat dissipation of the controller 160.

[0085] In addition, refer to Figures 3 to 5, a support member is provided in the water inlet hole 106 of the first plate 103, and the end of the pump shaft 170 is connected to the middle of the support member. The pump shaft 170 can be integrally formed with the first plate 103 as an insert, and the pump shaft 170 is preferably made of metal, which is used to install the rotor 120 and the stator 130 and has sufficient structural strength. Specifically, the rotor 120 is sleeved on the pump shaft 170, the stator 130 is inserted through the rotor 120 and sleeved on the pump shaft 170. The setting of the pump shaft 170 ensures the assembly accuracy of the rotor 120 and the stator 130, thereby ensuring the performance stability of the water pump function.

[0086] Referring to Figures 6 to 8 , the water valve 140 includes a valve housing 141 and an actuator 144. The valve housing 141 is integrally formed with the flow channel plate 100 (i.e., the second plate 104). The valve housing 141 and the flow channel plate 100 form a first chamber 142 and a second chamber 143, and the first chamber 142 and the second chamber 143 are arranged along the axial direction D1.

The first chamber 142 is communicated with the second chamber 143 through the valve hole 148, and the second chamber 143 is communicated with the water outlet 102. The pump housing 110 is provided with a connecting pipe 113. The first end of the connecting pipe 113 is communicated with the first stepped groove 111 in the pump housing 110, and the second end of the connecting pipe 113 is communicated with the first chamber 142, so that the pressurized cooling liquid in the pump housing 110 enters the first chamber 142 through the connecting pipe 113.

[0087] Optionally, referring to Figure 6 , the second chamber 143 can be configured to be divided into multiple chambers, each chamber is correspondingly provided with a valve hole 148, and the multiple chambers are correspondingly arranged with multiple water outlets 102, so that the cooling liquid can be correspondingly conducted to different water outlets 102, which is suitable for equipment with multi-channel heat dissipation requirements.

[0088] Furthermore, as shown in Figure 4 , the first plate 103 is formed with a support seat 108.

Referring to Figure 8, the actuator 144 includes a valve core 145, an elastic member 149, a driving element 150, and a cam 151. The valve core 145 passes through the valve hole 148 into the valve housing 141, and the valve core 145 is sleeved on the support seat 108.

Specifically, an annular protrusion 146 is provided on the side of the valve core 145. When the valve core 145 is located at the closed position, the annular protrusion 146 closes the valve hole 148, thereby preventing the cooling liquid in the first chamber 142 from being conducted to the water outlet 102 corresponding to the valve hole 148 through the valve hole 148. A sealing ring 147 is sleeved on the side of the annular protrusion 146, so that the annular protrusion 146 is hermetically connected to the inner wall of the valve hole 148, preventing the cooling liquid from leaking between the annular protrusion 146 and the valve hole 148.

[0089] The elastic member 149 is sleeved on the support seat 108 and connected to the valve core 145, applying a force to the valve core 145 towards the open position. The driving element 150 is connected to the valve housing 141 through a fastener, and the driving element 150 cooperates with the valve housing 141 to make the second chamber 143 airtight. The cam 151 is connected to the output shaft of the driving element 150, and the cam 151 abuts against the end of the valve core 145. When the driving element 150 is started, the contact point between the cam 151 and the driving element 150 changes along the axial direction D1 of the pump shaft 170, so that the cam 151 drives the valve core 145 to switch between the closed position and the open position.

[0090] In addition, the controller 160 is electrically connected to the driving element 150, and the switching of the water valve 140 is realized by controlling the rotation angle of the driving element 150. The driving element 150 can be selected as a servo motor, with precise control.

[0091] As an alternative, the water valve 140 can also be selected as a cylindrical valve or a ball valve.
