TECHNICAL FIELD

[0001] The present application relates to the technical field of thermal management and automobile, in particular to an integrated thermal management module with multi-way valve function. BACKGROUND

[0002] With the popularization of new energy vehicles, the importance and complexity of thermal management systems on new energy vehicles gradually increase, especially the complexity of the water circuit. The miniaturization and integration of thermal management systems have become a trend in the industry.

[0003] For thermal management products, the multi-way valve in the existing integrated module is an independent component that needs to be assembled with a flow channel plate to form a water-side integrated module. It has the following shortcomings:

[0004] ① The weight is relatively large, which is not conducive to the lightweight of the vehicle;

[0005] ② The assembly of the multi-way valve and the flow channel plate increases the sealing structure, and the module has a risk of leakage, which reduces the system reliability to a certain extent;

Further, the valve core assembly cooperates with the water flow channels in the flow channel plate assembly, and the valve core assembly is driven by the actuator to complete the connection or closing between different preset water flow channels, thereby realizing the multi-way connection function of the separate multi-way valve device in the prior art.

While ensuring the multi-way connection function, the valve body, the sealing connection between the valve body and the flow channel plate, and the mounting part of the valve body and the flow channel plate in the prior art are reduced, thereby significantly reducing the volume and weight of the heat management module. Meanwhile, fewer structures can reduce the arrangement position of the sealing structure, which is conducive to avoiding the leakage risk of the heat management module and improving the cooling effect and heat energy recycling rate of the heat management module. In summary, the integrated heat management module with the multi-way valve function has the advantages of simpler structure, more convenient manufacturing, fewer components, and better sealing performance, thereby having significant economic benefits.

[0028] In an optional embodiment, a valve cover is further included.

[0029] The valve cover is arranged on the flow channel plate, and the valve cover is connected with the containing cavity to form a closed chamber.

[0030] In an optional embodiment, the flow channel plate assembly includes a plurality of flow channel plates arranged in a stack.

[0031] In an optional embodiment, a module controller is further included.

[0032] The actuator and the water pump are connected with the module controller, and the module controller is configured to control the working states of the actuator and the water pump.

[0033] The beneficial effects of the embodiments of the present application include, for example:

Compared with the multi-way valve device in the prior art, which is arranged on the flow channel plate as a separate component, the integrated thermal management module with multi-way valve function integrates the valve body of the existing multi-way valve device on the flow channel, thereby reducing the structure of the valve body and the connection and sealing of the valve body with other components in the prior art. In this way, the weight and volume of the entire thermal management module are reduced, and the overall sealing effect is guaranteed, thereby improving the cooling performance and heat utilization rate of the thermal management module. In summary, the integrated thermal management module with multi-way valve function integrates the multi-way valve device and the flow channel plate, reduces weight and cost, and improves the reliability and assembly of the module. At the same time, the control function is integrated, the product cost is reduced, the assembly capability is enhanced, and the module has better versatility. BRIEF DESCRIPTION OF DRAWINGS

[0051] Figure 1 A structural schematic diagram of a heat management integrated module in the prior art, Figure 2 An assembly schematic diagram of a heat management integrated module in the prior art.

[0052] From Figure 1 And Figure 2As can be seen from the drawings, the existing integrated module at least includes an actuator unit 11, a multi-way valve 12, a rubber pad 13, a flow channel plate 14 and a water pump unit 15, and the existing integrated module is assembled by the five components. Among them, a plurality of water pump units 15 are arranged in the corresponding installation slots on the flow channel plate 14 one by one, and the water pump unit 15 is sealingly connected with the flow channel plate 14. The multi-way valve 12 is sealingly arranged on the surface of the flow channel plate 14 through the rubber pad 13. The actuator unit 11 is arranged on the multi-way valve 12 and connected with the valve core of the multi-way valve 12. Further, there is a flow channel in the flow channel plate 14 leading to different water pump units 15 and external interfaces, and the connection relationship between the flow channels in the flow channel plate 14 and the water pump units 15 is adjusted by the multi-way valve 12 to realize the water circuit switching function of various modes.

[0053] As can be seen from the drawings, the multi-way valve 12 in the existing integrated module is an independent component, which needs to be assembled with the flow channel plate 14 to jointly constitute the water side integrated module; there are the following shortcomings:

[0054] ① The weight is relatively large, which is not conducive to the lightweight of the whole vehicle;

[0055] ② The assembly of the multi-way valve 12 and the flow channel increases the sealing structure, and the module has a risk of leakage, which reduces the system reliability to a certain extent;

[0056] ③ The multi-way valve 12 is an independent component, and the cost is high.

[0057] In order to improve the above technical problems, an integrated thermal management module with a multi-way valve function is provided in the following embodiments.

[0058] Please refer to Figure 3 , Figure 4 and Figure 5 , the present embodiment provides an integrated thermal management module 20 with a multi-way valve function, comprising a flow channel plate assembly 100, an actuator 200, a valve core assembly 300 and a plurality of water pumps 400;

[0059] The valve core assembly 300 is movably arranged in the flow channel plate assembly 100;

[0060] The flow channel plate assembly 100 has a plurality of water flow channels, and the water pump 400 is arranged on the flow channel plate assembly 100, and the water pump 400 can be connected with the water flow channel;

[0061] The valve core assembly 300 is connected with the water flow channel; the actuator 200 is connected with the valve core assembly 300 to control the conduction or closing between different water flow channels.

[0062] The integrated heat management module 20 with the multi-way valve function is achieved by directly arranging the valve core assembly 300 in the flow channel plate assembly 100. Further, the valve core assembly 300 cooperates with the water flow channels in the flow channel plate assembly 100, and the valve core assembly 300 is driven by the actuator to complete the connection or closing between different preset water flow channels, thereby realizing the multi-way connection function of the separate multi-way valve 12 device in the prior art. The integrated heat management module 20 with the multi-way valve function eliminates the valve body and other components of the existing multi-way valve 12 device, and concentrates the functions of the valve body in the interior of the flow channel plate assembly 100. While ensuring the multi-way connection function, the valve body, the sealing connection between the valve body and the flow channel plate 14, and the mounting member of the valve body and the flow channel plate 14 in the prior art are reduced, thereby significantly reducing the volume and weight of the heat management module; meanwhile, fewer structures can reduce the arrangement position of the sealing structure, which is conducive to avoiding the leakage risk of the heat management module and improving the cooling effect and heat energy recycling rate of the heat management module. In summary, the integrated heat management module 20 with the multi-way valve function has the advantages of simpler structure, more convenient manufacturing, fewer components, and better sealing performance, thereby having significant economic benefits.

[0063] Please continue to refer to Figures 1 to 8 for more structural details of the integrated heat management module 20 with the multi-way valve function.

[0064] The flow channel plate assembly 100 is generally in the shape of a rectangular parallelepiped. The actuator 200 and the plurality of water pumps 400 are arranged on the top of the flow channel plate assembly 100, and the valve core assembly 300 is arranged on the flow channel plate assembly 100. The actuator 200 is arranged above the valve core assembly 300.

[0065] As can be seen from the figure, the plurality of water flow channels arranged in the flow channel plate assembly 100 include a plurality of water inlet flow channels 101 and a plurality of water outlet flow channels 102. The water inlet flow channels 101 are for the water flow to enter the valve core assembly 300, and the water outlet flow channels 102 are for the water flow to flow out of the valve core assembly 300.

[0066] It should be noted that in other embodiments of the present application, the water flow direction in the water flow channel (including the water inlet flow channel 101 and the water outlet flow channel 102, the same below, which will not be repeated) is not limited to a fixed flow direction, but can be adjusted or exchanged according to specific use scenarios.

[0067] Specifically, the integrated heat management module 20 with the multi-way valve function includes three water pumps 400. The flow channel plate assembly 100 has a first preset long side and a first preset short side, and the first preset long side and the first preset short side are arranged adjacent to each other.

[0068] Among the three water pumps 400, two water pumps 400 are arranged along the first preset long side in sequence, and one water pump 400 is arranged at the angle between the first preset long side and the first preset short side; the other water pump 400 is arranged along the first preset short side. The valve core assembly 300 is arranged in a direction parallel to the first preset long side.

[0069] As for the specific arrangement of the water pump 400, those skilled in the art can reasonably select and design according to actual needs, which is not specifically limited here. For example, the position and number of the water pump 400 can be adjusted to adapt to different actual situations, which is only an example and is not limited specifically.

[0070] Further, in the present embodiment, the water pump 400 has multiple different connection modes with the valve core assembly 300. Specifically:

[0071] The water outlet of the water pump 400 is connected to one end of the valve core assembly 300 through the water inlet flow channel 101;

[0072] The water inlet of the water pump 400 is connected to one end of the valve core assembly 300 through the water outlet flow channel 102;

[0073] The water inlet and outlet of the water pump 400 are directly connected to other heat management components outside the module through the inlet and outlet of the module, and then connected to the water inlet flow channel 101 and the water outlet flow channel 102 through other inlets and outlets of the module.

[0074] As for the specific arrangement of the water flow channel, those skilled in the art can reasonably select and design according to actual needs to adapt to different actual situations, which is not specifically limited here. This is only an example.

[0075] From Figure 3 , Figure 4 and Figure 5 , it can be seen that the flow channel plate assembly 100 has a containing cavity 110, and the water flow channels are all connected to the containing cavity 110; the valve core assembly 300 is movably arranged in the containing cavity 110 to control the conduction or closing of different preset water flow channels.

[0076] Specifically, in the present embodiment, the water inlet flow channel 101 and the water outlet flow channel 102 are both connected to the containing cavity 110; the valve core assembly 300 is movably arranged in the containing cavity 110 to control the conduction or closing of the preset water inlet flow channel 101 and the preset water outlet flow channel 102.

[0077] Further, in the present embodiment of the present application, the integrated thermal management module 20 with the multi-way valve function further comprises a valve cover 21; the valve cover 21 is arranged on the flow channel plate 14, and the valve cover 21 is connected with the containing cavity 110 to form a closed cavity. The valve cover 21 and the containing cavity 110 enclose a closed space in which the valve core assembly 300 can move freely. In this way, the valve body, the sealing structure between the valve body and the flow channel plate 14, etc. in the prior art when the multi-way valve 12 mechanism is arranged separately can be omitted, and the connection relationship between the valve core control flow channel and the water pump 400 is retained to realize the function of switching the water circuit in various modes. In summary, such a thermal management module reduces the overall weight of the module, realizes lightweight, reduces the volume of the module, is beneficial to the vehicle layout, reduces the number of parts, reduces the cost, reduces the sealing structure between the multi-way valve 12 and the flow channel plate 14, reduces the risk of leakage, and provides product reliability.

[0078] Further, in the present embodiment of the present application, the integrated thermal management module 20 with the multi-way valve function further comprises a module controller 22; the actuator 200 and the water pump 400 are connected with the module controller 22, and the module controller 22 is configured to be able to control the working states of the actuator 200 and the water pump 400.

[0079] It should be noted that the water pump 400 and the actuator 200 of the integrated thermal management module in the prior art are controlled independently. That is, the water pump 400 is controlled by a water pump 400 controller to deliver liquid, and the actuator 200 is controlled by an execution controller to move the valve core to adjust the operating state of the multi-way valve 12. In this arrangement, the water pump 400 controller and the execution controller need to occupy additional space of the module, and more controllers will cause wiring difficulties and make the operation control process complex.

[0080] In the present embodiment, the control of the actuator 200 and the water pump 400 is integrated in one controller, which reduces the cost of the actuator 200 and the water pump 400, reduces the volume of the product, reduces the difficulty of wiring arrangement, is beneficial to the vehicle layout and installation of the controller, improves the EMC performance of the product, adjusts the software of the controller according to different control function requirements, and improves the versatility of the product.

[0081] It should be noted that the controller can increase more device control (different number of water pumps 400, multi-way valves 12, electronic expansion valves, etc.) according to specific needs.

[0082] From Figures 4 to 8It can be seen from the above that, in the embodiment of the present application, the valve core assembly 300 comprises at least one multi-way valve core 310 and at least one ball valve core 320; the accommodating cavity 110 comprises a multi-way cavity 111 and a ball valve cavity 112 connected with each other; the multi-way valve core 310 is rotatably arranged in the multi-way cavity 111, and the ball valve core 320 is rotatably arranged in the ball valve cavity 112; and the water flow channels are connected with the ball valve cavity 112 and the multi-way cavity 111 respectively.

[0083] Specifically, in the embodiment, the valve core assembly 300 comprises only one multi-way valve core 310 and one ball valve core 320. The multi-way cavity 111 has a plurality of water inlet ports and a plurality of water outlet ports to seal and connect different water inlet flow channels 101 and different water outlet flow channels 102; that is, the multi-way cavity 111 is connected with a plurality of water inlet flow channels 101 and a plurality of water outlet flow channels 102 respectively. The ball valve cavity 112 has a communication port 130 directly with the multi-way cavity 111 to communicate the ball valve cavity 112 with the multi-way cavity 111, and the communication port 130 is the water inlet port of the ball valve cavity 112. The ball valve cavity 112 has two water outlet ports to connect two water outlet flow channels 102.

[0084] The ball valve core 320 in the form of a spherical ball adjusts the communication or disconnection of the communication port 130 with different water outlet ports by rotation; and the multi-way valve core 310 in the form of a cylinder can selectively connect different water inlet ports with the communication port 130 and connect different water inlet ports with different water outlet ports by rotation. The multi-way valve core 310 and the ball valve core 320 cooperate to achieve multiple adjustment modes, thereby improving the cooling and heat dissipation capacity of the thermal management system.

[0085] It should be noted that, in other embodiments of the present application, the valve core assembly 300 can comprise one multi-way valve core 310 and a plurality of ball valve cores 320 to achieve more adjustment modes; further, the multi-way cavity 111 and the ball valve cavity 112 can be separated from each other to control different water flow channels separately; that is, the number of the multi-way valve core 310 and the ball valve core 320 is not limited, and the connection mode between the multi-way cavity 111 and the ball valve cavity 112 is not limited, and a person skilled in the art can make reasonable selection and design according to actual needs to adapt to different actual situations, which is only an example.

[0086] In other embodiments, the water inlet port of the ball valve core 320 is not limited to the communication port 130 directly between the ball valve cavity 112 and the multi-way cavity 111, but can be other water inlet ports arranged separately, which is only an example.

[0087] Further, in other embodiments, a valve plate can be arranged at the communication port 130 to selectively connect or disconnect the multi-way cavity 111 and the ball valve cavity 112.

[0088] Optionally, the rotation axis of the multi-way valve spool 310 and the rotation axis of the ball valve spool 320 are parallel to each other. Such an arrangement can further reduce the volume of the valve spool assembly 300, thereby improving the space rate of the integrated thermal management module 20 with multi-way valve function, and at the same time achieving the purpose of weight reduction.

[0089] Continuing to refer to Figure 4 and Figure 5 As can be seen from the drawings, in the present embodiment of the present application, the integrated thermal management module 20 with multi-way valve function further comprises a ring-shaped multi-way valve sealing member 510; the multi-way valve sealing member 510 is arranged circumferentially in the multi-way chamber 111; and the outer wall of the multi-way valve spool 310 can be rotationally fitted with the inner wall of the multi-way valve sealing member 510. The ring-shaped multi-way valve sealing member 510 can not only ensure the sealing of the multi-way valve spool 310, but also reduce the size of the sealing structure, thereby ensuring that the valve spool assembly 300 has more flexible activity space.

[0090] Further, the integrated thermal management module 20 with multi-way valve function further comprises a ball valve sealing member 520; the ball valve sealing member 520 is arranged in the ball valve chamber 112; and the ball valve sealing member 520 is located between the ball valve spool 320 and the water outlet flow channel 102. The ball valve sealing member 520 ensures the sealing effect during the operation of the ball valve, which is conducive to improving the overall working efficiency of the thermal management module. In the embodiment, the integrated thermal management module 20 with multi-way valve function further comprises a rotary sealing member 530; the rotary sealing member 530 is arranged at the rotation shaft of the multi-way valve spool 310 and the ball valve spool 320, respectively. The rotary sealing member 530 can ensure the sealing of the rotation axis of the valve spool assembly 300. Please continue to refer to Figures 3 to 5 As can be seen from the drawings, the flow channel plate assembly 100 comprises a plurality of flow channel plates 14 arranged in a stack. In the present embodiment, the flow channel plate assembly 100 comprises a first flow channel plate 121, a second flow channel plate 122 and a third flow channel plate 123 arranged in a stack.

[0091] The first flow channel plate 121 is provided with a water pump 400, and the actuator 200, the valve cover 21 and the module controller 22 are all arranged on the first flow channel plate 121. The first flow channel plate 121 is provided with a valve spool channel for mounting the multi-way valve spool 310 and the ball valve spool 320, and the valve spool channel and the second flow channel plate 122 together enclose the containing cavity 110.

[0092] The second flow channel plate 122 is provided with another two water pumps 400, and the first flow channel plate 121 and the second flow channel plate 122 together enclose part of the water flow channel (including the water inlet flow channel 101 and the water outlet flow channel 102, the same below), and the second flow channel plate 122 and the third flow channel plate 123 together enclose the remaining water flow channel.

[0093] Please refer to Figure 6 , Figure 7And Figure 8 As a use mode, the integrated thermal management module 20 with the multi-way valve function in the embodiment has six water inlet ports and six water outlet ports. Specifically, the flow channel plate assembly 100 is provided with nine ports numbered A, B, C, D, E, F, G, H and I, and each port cooperates with each other to form different water inlet flow channels 101 or water outlet flow channels 102.

[0094] Among them, A, D, F, H are water inlet flow channels 101, B, C, E, G, I are water outlet flow channels 102. Among them, the A port water inlet port can be communicated with the communication port 130.

[0095] Specifically, the ports connected with the multi-way valve core 310 are eight ports of A, B, C, D, F, G, H and the communication port 130, so that the multi-way valve core 310 can realize the function of an eight-way valve. That is, the multi-way cavity 111 has four water inlet flow channels 101 and four water outlet flow channels 102.

[0096] Specifically, the ports connected with the ball valve core 320 are three ports of the communication port 130, E and I, so that the multi-way valve core 310 can realize the function of a three-way valve. That is, the two flow channels E and I of the ball valve cavity 112 are both water outlet flow channels 102.

[0097] Through such port setting, the scheme can realize an 8-way+3-way adjustment mode, and the specific circulation mode is as follows:

In summary, the embodiment of the present application provides an integrated thermal management module 20 with a multi-way valve function, which has at least the following advantages:

[0100] 1.
