Description

Technical Field

[0001] This application relates to the field of thermal management technology, such as thermal management technology for automotive, commercial, residential or energy storage applications, and particularly to an integrated module. Background Technology

[0002] The thermal management system includes a flow channel plate assembly, a mounting base, and a connector. The mounting base and connector are fixedly connected to the flow channel plate assembly and are located on the same side of the flow channel plate assembly. The flow channel plate assembly has a flow channel. A valve component is mounted on the mounting base. The inlet or outlet of the valve component is connected to one port of the connector through the flow channel of the flow channel plate assembly. The other port of the connector is connected to other external components in the system. The flow channel extends in a plane perpendicular to the thickness direction of the flow channel plate assembly, which causes the size of the flow channel plate assembly in this space to increase, which is not conducive to the miniaturization of integrated components. Summary of the Invention

[0003] The purpose of this application is to provide an integrated module that facilitates miniaturization of the integrated module.

[0004] To achieve the above objectives, this application adopts the following technical solution:

[0005] An integrated component includes a valve component, a flow channel plate assembly, a mounting base, and a connector. The mounting base is fixedly connected to the flow channel plate assembly, and the connector is fixedly connected to the flow channel plate assembly. Along the thickness direction of the flow channel plate assembly, the mounting base is located on one side of the flow channel plate assembly, and the connector is located on the other side of the flow channel plate assembly. The mounting base includes a mounting cavity, a first port, and a second port. At least a portion of the valve component is located in the mounting cavity. The first port is located on the side of the mounting base facing the flow channel plate assembly, and the valve component is capable of controlling the opening and closing of the first port and the second port. The connector includes a first interface, a second interface, and a connecting channel connecting the first interface and the second interface. Along the thickness direction of the flow channel plate assembly, the first interface is located on the side of the connector facing the flow channel plate assembly and communicates with the first port. A first plane is defined, which is perpendicular to the thickness direction of the flow channel plate assembly. The projections of the wall forming the first interface and the wall forming the first port onto the first plane at least partially coincide.

[0006] In the technical solution provided in this application, the connector and the mounting base are arranged on different sides of the flow channel plate assembly. The projection of the wall forming the first interface and the wall forming the first opening on the first plane at least partially overlaps. In related technologies, the connector and the mounting base are arranged on the same side of the flow channel plate assembly. The connector and the mounting base need to be connected to the flow channel of the flow channel plate assembly. If the two ends of the flow channel are on the same side of the flow channel plate assembly, the flow channel extends in the first plane. The aforementioned flow channel, connector, and mounting base occupy the space of the flow channel plate assembly in the first plane, which increases the size of the flow channel plate assembly. In the solution of this application, the connector and the mounting base are arranged on different sides of the flow channel plate assembly. The flow channel connecting the first interface and the first opening extends along the thickness direction of the flow channel plate assembly, which relatively reduces the space occupied by the flow channel plate assembly in the first plane. This is beneficial to the miniaturization and weight reduction of the flow channel plate assembly, and thus beneficial to the miniaturization and weight reduction of the integrated assembly.

[0027] The integrated module of this application can be applied to a thermal management system, which can be a vehicle thermal management system, such as a thermal management system for new energy vehicles. Of course, the application areas of the integrated module of this application are not limited to those described herein, and can also be used in other fields, such as household air conditioning and energy storage systems.

[0028] Figures 1-13An integrated module is provided, including a valve component 40, a flow channel plate assembly 10, a mounting base 20, and a connector 30. The mounting base 20 is fixedly connected to the flow channel plate assembly 10, and the connector 30 is fixedly connected to the flow channel plate assembly 10. Along the thickness direction of the flow channel plate assembly 10, the mounting base 20 is located on one side of the flow channel plate assembly 10, and the connector 30 is located on the other side of the flow channel plate assembly 10. The mounting base 20 includes a mounting cavity 201, a first opening 202, and a second opening 203. At least a portion of the valve component 40 is located in the mounting cavity 201, and the first opening 202 is located on the side of the mounting base 20 facing the flow channel plate assembly 10. The component 40 can control the opening and closing of the first port 202 and the second port 203. The connector 30 includes a first interface 301, a second interface 302 and a connecting channel 303. The connecting channel 303 connects the first interface 301 and the second interface 302. Along the thickness direction of the flow channel plate assembly 10, the first interface 301 is located on the side of the connector 30 facing the flow channel plate assembly 10. The first interface 301 is connected to the first port 202 and defines a first plane. The first plane is perpendicular to the thickness direction of the flow channel plate assembly 10. The projection of the wall forming the first interface 301 and the wall forming the first port 202 on the first plane at least partially coincides.In this application, the mounting base 20 and the connector 30 are respectively disposed on both sides of the flow channel plate assembly 10. The mounting base 20 includes a mounting cavity 201, a first port 202, and a second port 203. When the valve component 40 is not installed, the first port 202 and the second port 203 are connected to the mounting cavity 201. This can be understood as one of the first port 202 and the second port 203 being a fluid inlet and the other being a fluid outlet. When the valve component 40 is installed in the mounting cavity 201, the valve component 40 can control the opening degree of the valve port. The connection 30, which controls the on / off relationship or fluid flow rate between the first port 202 and the second port 203, includes a first interface 301 and a second interface 302. The first interface 301 communicates with the first port 202 of the mounting base 20, and the second interface 302 is connected to other components in the thermal management system, such as a compressor, evaporator, and condenser. In related technologies, the connection 30 and the mounting base 20 are located on the same side of the flow channel plate assembly 10. Fluid flowing out from either the first port 202 or the second port 203 of the mounting base 20... And / or fluid flowing in from either the first port 202 or the second port 203 of the mounting base 20 needs to communicate with the connector 30 through the flow channel 101 of the flow channel plate assembly 10, and the connector 30 and the mounting base 20 are located on the same side of the flow channel plate assembly 10, that is, the two ports of the flow channel 101 are on the same side of the flow channel plate assembly 10. The flow channel 101 extends along the first plane on the flow channel plate assembly 10. The flow channel 101, the connector 30, and the mounting base 20 occupy the space of the flow channel plate assembly 10 within the first plane. The larger the size of component 10, the better. In this application, the connector 30 and the mounting base 20 are located on opposite sides of the flow channel plate assembly 10. The projection of the wall forming the first interface 301 and the wall forming the first opening 202 on the first plane is at least partially coincident. Then, the flow channel 101 connecting the first interface 301 and the first opening 202 extends along the thickness direction of the flow channel plate assembly 10, which relatively reduces the space occupied by the flow channel plate assembly 10 in the first plane. This is beneficial to the miniaturization and weight reduction of the flow channel plate assembly 10, and thus to the miniaturization and weight reduction of the integrated components.

[0029] like Figure 1-3As shown, the flow channel plate assembly 10 includes a first plate 11 and a second plate 12, which are stacked and fixedly connected. The integrated assembly includes a groove located on the first plate 11 and / or the second plate 12. The first plate 11 and the second plate 12 cooperate to form the flow channel 101 of the flow channel plate assembly 10. It is understood that the first plate 11 has a groove and a planar structure, and the second plate 12 has a groove and a planar structure. The groove of the first plate 11 and the groove of the second plate 12 cooperate to form the flow channel 101 of the flow channel plate assembly 10, or the planar structure of the first plate 11 and the groove of the second plate 12 cooperate to form the flow channel 101, or the groove of the first plate 11 and the planar structure of the second plate 12 cooperate to form the flow channel 101. Of course, the first plate 11 may have a generally flat structure, and the second plate 12 may have a groove, or the first plate 11 may have a groove, and the second plate 12 may have a planar structure; all of these are within the scope of protection of this application. Specifically, in this technical solution, the first plate 11 is an integral flat plate structure, and the second plate 12 includes a groove 121. The opening of the groove 121 faces the first plate 11 and is formed by a stamping process. The flow channel plate assembly 10 includes multiple second plates 12, which are respectively fixedly connected to the first plate 11. The first plate 11 and the second plate 12 are made of metal materials, such as aluminum alloy, steel, or other metal materials. Because aluminum alloy is relatively light, the mold cost is low when using a stamping process, and the first plate 11 and the second plate 12 can be relatively thin, which is beneficial to the lightweight of the flow channel plate assembly 10. The first plate 11 includes a channel 110 that penetrates the first plate 11, meaning the channel 110 has openings at both opposite ends of the first plate 11. The mounting base 20 is welded and fixed to the first plate 11, and the connecting piece 30 is also welded and fixed to the first plate 11. The channel 110 connects the first opening 202 and the first interface 301, forming a wall of the channel 110, a shadow of the first interface 301, and a projection of the wall of the first opening 202 onto a first plane that at least partially overlaps. In this technical solution, the first plate 11 is an integral plate structure, including the channel 110 that penetrates the first plate 11. It is understood that the axial direction of the channel 110 is parallel to the thickness direction of the first plate 11. This channel 110 structure is advantageous for processing, and the manufacturing process is relatively simple. Alternatively, the axial direction of the channel 110 may be angled to the thickness direction of the first plate 11.

[0030] Combination Figure 1 , 4-5. The integrated module includes multiple mounting bases 20. Each mounting base 20 includes a main body 21, a channel 22, and a fixing part 25. The main body 21 is generally cylindrical and forms a mounting cavity 201 for mounting the valve component 40. The channel 22 forms a channel 221 and protrudes outward from the outer wall of the main body 21 along its radial direction. The fixing part 25 protrudes outward from the outer wall of the main body 21. The valve component 40 is fixedly connected to the fixing part 25. The projections of the fixing part 25 and the channel 22 on a first plane at least partially overlap. The valve component 40 has a connecting plate 41, a valve core assembly, and a coil assembly 42. Part of the valve core assembly is located within the mounting base 20, and part of the valve core assembly is located within the sensing wire cavity of the coil assembly 42. One end of the connecting plate 41 is fixedly connected or limited to the coil assembly 42, and the other end of the connecting plate 41 is fixedly connected or limited to the mounting base 20. In this embodiment, the connecting plate 41 is fixed to the fixing part 25 of the mounting base 20 by screws. Along the thickness direction of the flow channel plate assembly 10, the fixing part 25 is farther away from the first plate 11 relative to the channel part 22, and the projections of the fixing part 25 and the channel part 22 on the first plane at least partially overlap, which can improve the space utilization. Of course, in other technical solutions, such as Figure 1The valve component 40 includes a connector 43, and the coil assembly 42 is point-connected to the connector 43. Along the radial direction of the valve component 40, part of the connector 43 is located on one side of the coil assembly 42 and protrudes from the outer side wall of the coil assembly 42. The projections of the connector 43 and the channel portion 22 on the first plane at least partially overlap. The space above the channel portion 22 is fully utilized to arrange the connector protruding from the coil assembly 42, or a fixing portion 25 for fixing the coil assembly 42 is provided, which can improve space utilization. According to the system settings, the above two layouts and structures can be reasonably utilized to make the integrated module more compact and facilitate the miniaturization of the integrated module. In this technical solution, the axis of the first opening 202 forming the mounting base 20, the axis of the hole 110 forming the first plate 11, and the axis of the first interface 301 forming the connector 30 are arranged in approximately parallel directions. That is, the axes of the first opening 202, the hole 110, and the first interface 301 can be parallel to each other and staggered. Of course, in order to make processing and installation simpler and more convenient, in the following technical solution, the first opening 202, the hole 110, and the first interface 301 are arranged in approximately coaxial directions. The above "approximately" refers to the range of tolerances. Specifically, the mounting base 20 includes a first opening 202 and a second opening 203. The first opening 202 communicates with the mounting cavity 201, and the second opening 203 communicates with the mounting cavity 201 through a channel 221. The side wall of the mounting cavity 201 has a connecting opening 204, which communicates with the channel 221. Along the axial direction of the mounting base 20, the first opening 202 is located on the side opposite to the opening of the mounting cavity 201, that is, the first opening 202 is formed at the bottom of the main body 21. For ease of installation and processing, the first opening 202 and the mounting cavity 201 are approximately coaxial. Here, approximately coaxial means that the axis of the first opening 202 and the axis of the mounting cavity 201 may have tolerances due to processing issues, and are not absolutely coaxial. The main body 21 of the mounting base 20 has a generally cylindrical structure. The main body 21 includes a mounting cavity 201 for accommodating the valve component 40. The shape of the main body 21 is roughly the same as that of the valve component 40. Under the condition of meeting the strength requirements, the cylindrical structure can reduce the volume and weight to a certain extent. The channel portion 22 protrudes outward from the outer wall of the main body 21 along the radial direction of the mounting cavity 201, and has a generally L-shaped structure. In this technical solution, the structure of the mounting base 20 is reasonably designed by using forging or die casting methods, thereby optimizing the volume and weight of the mounting base 20.Mounting base 20 includes mating part 24 and mounting part 23. The mating part 24 has a planar structure and protrudes towards the first plate 11 relative to the mating part 24 along the thickness direction of the flow channel plate assembly 10. A first opening 202 is formed in the mounting part 23. The mounting part 23 is located in the channel 110 of the first plate 11, that is, the mounting part 23 is placed in the channel 110 of the first plate 11. The outer wall of the mounting part 23 is interference-fitted or clearance-fitted with the inner wall of the channel 110. The mating part 24 is attached to the first plate 11 and welded to it. The surface of the mating part 24 and / or the surface of the first plate 11 is coated with a solder layer and fixed by brazing. The mounting base 20 has a positioning post 123 located in the mating part 24 and extending towards the first plate 11 relative to the end face of the mating part 24. A positioning hole 113 is provided at the relative position of the first plate 11. During assembly, the positioning post 123 is placed in the positioning hole 113 to restrict the movement of the mounting base 20 relative to the first plate 11. The mounting base 20 is provided with a mounting part 23 located in the channel 110, which also plays a limiting role to a certain extent. The positions of the positioning post 123 and the positioning hole 113 can be interchanged, that is, the positioning post 123 is located in the first plate 11 and the positioning hole 113 is located in the mounting base 20. Of course, in other embodiments, the mounting base 20 is welded and fixed to the first plate 11, and the first opening 202 is formed in the mating part 24, that is, the first opening 202 is located in the planar structure of the mating part 24. The mating part 24 of the mounting base 20 is welded and fixed to the first plate 11, so that the end wall forming the first opening 202 mates with the end face of the end wall forming the channel 110; or a first limiting part 111 is formed on the first plate 11. Along the thickness direction of the flow channel plate assembly 10, the first limiting part 111 protrudes in the direction of the end face of the first plate 11 relative to the mounting base 20. The first limiting part 111 forms part of the channel 110. The first limiting part 111 is located in the first opening 202. The first limiting part 111 is placed in the first opening 202 of the mounting base 20, and the mating part 24 of the mounting base 20 is attached to and welded and fixed to the first plate 11. In this technical solution, the second port 203 is formed on the bottom wall of the channel portion 22, and the second port 203 is in the same direction as the first port 202, and both face the first plate 11. That is, the second port 203 is formed in the mating portion 24 of the mounting base 20. The second port 203 is connected to another hole 110 of the first plate 11, and it is connected to the flow channel 101 on the flow channel plate assembly 10. That is, the fluid enters the second port 203 and the channel 221 of the mounting base 20 through the flow channel 101 on the flow channel plate assembly 10, enters the mounting cavity 201, and after the valve member 40 adjusts the valve opening, it flows out from the first port 202 of the mounting base 20, passes through the hole 110 of the first plate 11, and enters the connector 30.

[0031] The connector 30 includes a first interface 301, a connecting channel 303, and a second interface 302. The connecting channel 303 connects the first interface 301 and the second interface 302. The connector 30 has a roughly block-shaped structure. The first interface 301 is positioned opposite to the first port 202 and is connected to the first port 202. The second interface 302 is mainly used to connect other thermal management components in the thermal management system. The position of the second interface 302 on the connector 30 is set according to actual needs. In this technical solution, the second interface 302 is positioned opposite to the first interface 301. That is, along the thickness direction of the flow channel plate assembly 10, the connecting channel 303 passes through the connector 30 and forms two openings on the end face of the connector 30, namely the first interface 301 and the second interface 302. The first interface 301 and the second interface 302 are positioned opposite to each other, which is conducive to machining. The direct penetration method shortens the length of the flow channel 101 and helps to reduce flow resistance. In this technical solution, the connector 30 includes an interface portion 31 and a joint portion 32. The joint portion 32 is generally planar and is welded and fixed to the first plate 11. Along the thickness direction of the flow channel plate assembly 10, the interface portion 31 protrudes towards the first plate 11 relative to the joint portion 32. The first interface 301 is located at the interface portion 31, and the interface portion 31 is located at the channel 110. The interface portion 31 is placed in the channel 110, and the outer wall of the interface portion 31 is interference-fitted or clearance-fitted with the inner wall forming the channel 110. The joint portion 32 is connected to the first plate 11. 11. The interface 31 of the connecting part is fitted and welded to fix it. The end face of the interface 31 of the connecting part and the end face of the mounting part 23 of the mounting base 20 are separated to reduce the interference between the interface 31 and the mounting part 23 during the assembly process. For convenient and accurate assembly, a positioning post 123 is provided on the connecting part 30 and a positioning hole 113 is provided on the first plate 11. The cooperation between the positioning post 123 and the positioning hole 113 restricts the movement of the connecting part 30 relative to the first plate 11. Its specific structure is the same as or similar to that of the mounting base 20, and will not be described in detail. In other embodiments, the assembly structure of the connector 30 and the first plate 11 is as follows: the connector 30 includes a joint 32, which has a generally planar structure, and the first interface 301 is formed on the planar structure of the joint 32. The joint 32 is directly welded and fixed to the end face of the first plate 11; or the first plate 11 includes a second limiting part 112, which protrudes from the end face of the first plate 11 toward the connector 30 along the thickness direction of the flow channel plate assembly 10. The second limiting part 112 forms part of the channel 110, and at least part of the second limiting part 112 is located at the first interface 301.

[0032] The integrated module includes multiple valve components 40, and the number of mounting bases 20 is the same as the number of valve components 40, and they are set in a one-to-one correspondence, such as... Figure 1As shown, the multiple valve components 40 include electrically controlled valve components 40 and mechanical valve components 40. The electrically controlled valve components 40 include expansion valves and solenoid valves. Depending on the thermal management system, the electrically controlled valve components 40 may also include ball valves, column valves, or other components capable of adjusting the communication relationship between flow channels 101. The mechanical valve components 40 include one-way valve components 40, or other valve components 40 that can adjust the communication relationship of the corresponding first flow channel 101 using only mechanical structures. The connector 30 is used to connect other components of the thermal management system, mainly for connecting thermal management components outside the integrated assembly, such as compressors, liquid receivers, and external heat exchangers 60. Depending on the system, the first port 202 is connected to the first interface 301 on the mounting base 20, such as... Figure 8 , 10 As shown in Figure -11, the plurality of mounting bases 20 include a first mounting base 20A. The first opening 202 of the first mounting base 20A is substantially coaxially arranged with the mounting cavity 201, that is, the first opening 202 is located on the bottom wall of the main body 21, and the first opening 202 communicates with the mounting cavity 201 through a flow channel 2111. The first opening 202 and the mounting cavity 201 are coaxially arranged, and the length of the flow channel 2111 is the wall thickness of the bottom wall forming the receiving cavity. This structure relatively reduces the volume of the mounting base 20 and shortens the length of the flow channel 2111. To further reduce fluid flow resistance, the second port 203 of the mounting base 20 is connected to the flow channel 101 on the flow channel plate assembly 10 through the hole 110 of the first plate 11. The second port 203 is located upstream of the valve port, and the first port 202 is located downstream of the valve port. That is, the fluid flows into the channel 221 and the mounting cavity 201 through the second port 203, enters the first port 202, the hole 110, and the first interface 301 through the valve port, and then flows into the thermal management component outside the integrated assembly through the second interface 302. In other technical solutions, such as Figure 4-7 As shown, the plurality of mounting bases 20 include a second mounting base 20B. The first port 202 of the second mounting base 20B is connected to the first interface 301 of the connector 30. The first port 202 is connected to the mounting cavity 201 through the channel 221 of the channel portion 22. The second port 203 is arranged approximately coaxially with the mounting cavity 201 and is connected to the flow channel 101 of the flow channel plate assembly 10. The first port 202 is located upstream of the valve port, and the second port 203 is located downstream of the valve port. That is, fluid flows from the thermal management component outside the integrated assembly through the first interface 301 of the connector 30, the first port 202 of the mounting base 20, the channel 221, the valve port, and the second port 203 into the flow channel 101 of the flow channel plate assembly 10. Depending on the thermal management system, the connector 30 can be selectively connected to the outlet or inlet of the valve component 40.

[0033] Reference Figure 1The integrated module includes an adapter 50, which is welded and fixed to the first plate 11. The adapter 50 and the mounting base 20 are located on the same side of the flow channel plate assembly 10, and the adapter 50 is connected to the flow channel 101 of the flow channel plate assembly 10. The fixing method of the adapter 50 to the flow channel plate assembly 10 is the same as or similar to that of the connector 30, and will not be described in detail here. The adapter 50 includes an external interface, and its function is the same as that of the connector 30. The external interface of the adapter 50 is connected to the thermal management component not installed in the integrated assembly. The connector 30 is connected to the inlet or outlet of the valve component 40, and the adapter is connected to the flow channel 101.

[0034] In this application, the first plate 11 is an integral flat plate structure. The first plate 11 includes multiple channels 110, including a first channel 1101 and a second channel 1102. The first channel 1101 connects to the first opening 202 and the first interface 301. The second channel 1102 connects to the second opening 203 and the flow channel 101 of the flow channel plate assembly 10. The flow channel plate assembly 10 includes multiple second plates 12. The second plates 12 include grooves 121. Along the thickness direction of the flow channel plate assembly 10, the opening of the grooves 121 faces the first plate 11. The multiple second plates 12 are welded and fixed to the first plate 11 respectively. The first plate 11 and the second plates 12 are joined to form the flow channel 101 of the flow channel plate assembly 10. The second plates 12 can selectively connect to at least two channels 110 according to the flow path of the thermal management system. The second plate 12 includes a groove 121 and a flange 122. The flange 122 is fitted and welded to the first plate 11. For weight reduction, the width of the flange 122 is designed to be as small as possible, just enough to meet the welding strength requirements of the first plate 11 and the second plate 12. A positioning post 123 is provided in the flange 122 of the second plate 12, and a positioning hole 113 is provided in a corresponding position in the first plate 11. The positioning post 123 and the positioning hole 113 cooperate to restrict the movement of the second plate 12 relative to the first plate 11. The first plate 11 is also provided with a heat insulation groove 114, which is used to reduce harmful heat transfer between the high-temperature fluid and the low-temperature fluid in the flow channel 101. In addition to the positioning holes 113 and positioning posts 123 mentioned above, the positioning solution can also adopt the form of welding pre-positioning. In this technical solution, the fixing relationship of the mounting base 20, connector 30, adapter 50, first plate 11, second plate 12, etc. is fixed by welding. Moreover, the furnace brazing adopted in this application can pre-fix the mounting base 20, connector 30, adapter 50 and second plate 12 on the first plate 11 by spot welding after the components are assembled, and then send them into the furnace for brazing. The above solution can simplify the tooling fixtures.

[0035] In this application, the first plate 11 adopts an integral plate structure. The first plate 11 is provided with channels 110, heat insulation grooves 114, and positioning holes 113. Its structure is relatively simple and does not have a complex groove structure. Its manufacturing process is relatively simple. Multiple second plates 12 are welded to the first plate 11 to form flow channels 101. Compared with the single whole plate solution, the structure of the mold is relatively simple. Moreover, the arrangement of valves and flow channels 101 can be considered as much as possible at the setting point. The manufacturing cost of the same second plate 12 is reduced. In addition, the solution of multiple second plates 12 reduces the weight of the flow channel plate assembly 10 to a certain extent. The reserved space between two second plates 12 can be used to set the connector 30, which is conducive to the miniaturization of the integrated module.

[0036] In this embodiment, the integrated module also includes a heat exchanger 60, which is welded to the first plate 11. The heat exchanger 60 and the mounting base 20 are located on the same side of the first plate 11, and the stacking direction of the heat exchanger 60 plates is parallel to the thickness direction of the flow channel 101 plate. Specifically, the plates of the heat exchanger 60 closest to the first plate 11 are directly welded to the first plate 11. This method eliminates the installation steps of the heat exchanger 60, saving manufacturing costs. In addition, it saves the mounting plate of the heat exchanger 60, which also reduces manufacturing costs by reducing the number of parts, and at the same time, it is conducive to the lightweighting of the integrated components.

It should be pointed out that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the present invention.
