[0026] In order to better understand the technical solutions of the present application, the embodiments of the present application are described in detail below with reference to the drawings.

[0027] It should be clear that the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0028] The heat management module has a channel for circulating a heat exchange medium. During installation, impurities fall into the channel from the components included in the heat management module, or impurities are generated inside the module after a long period of operation, which can easily cause the channel to be blocked and affect heat exchange to some extent. In the field of energy storage heat management, due to the relatively large heat exchange demand, for example, the heat exchange demand of an energy storage power station is much larger than that of a car, the flow of the heat exchange medium in the heat management system in the energy storage field is larger, and the total amount of impurities in the heat exchange system is also larger. In order to reduce the risk of channel blockage caused by impurities in the heat exchange medium and reduce the impact of impurities on heat exchange, the related art uses a filter to filter the fluid. For example, the filter can be externally connected to the heat management module through a pipeline. However, in the related art, the integration of the filter and the heat management module is low.

The flow channel integrated piece 1 has a flow channel 12, the first channel 101 includes the flow channel 12. At least one of the first filter cavity 103 and the second filter cavity 104 is in communication with the flow channel 12. The flow channel integrated piece 1 includes a mounting portion 11, the filter element 2 and the shell 3 are respectively mounted on the mounting portion 11, for example Figures 1-4 or Figure 13 and Figure 14The filter core 2 is fixedly connected or limitingly connected with the mounting portion 11, and the shell 3 is fixedly connected or limitingly connected with the mounting portion 11, thereby improving the integration of the thermal management assembly 100.

[0031] In some embodiments, the filter core 2 is sealingly connected with the mounting portion 11. In some embodiments, the filter core 2 is detachably connected with the mounting portion 11. The detachable connection means that the two can be switched from a combined state to a separated state, and can also be switched from a separated state to a combined state.

[0032] In some embodiments, for example Figure 7 As shown, the filter core 2 includes a support 21, and the support 21 includes a first body portion 22. In some embodiments, the first body portion 22 includes a first connecting portion 24 and a filter portion 23. The first connecting portion 24 is connected with the filter portion 23, and the first connecting portion 24 and the filter portion 23 are both located at the periphery of a first inner cavity 221. The first connecting portion 24 is connected with the mounting portion 11, and a first port 222 is arranged on the first connecting portion 24. The filter portion 23 is mainly used for filtering fluid alone or in cooperation with other components (for example, a filter screen 26), and the filter portion 23 has a through hole 210 penetrating the wall of the filter portion 23. The through hole 210 communicates with the first inner cavity 221.

[0033] In some embodiments, the support 21 includes a first protruding portion 25, which protrudes from the first body portion 22 in a direction perpendicular to the height direction of the filter core 2. In some embodiments, the first protruding portion 25 is connected with the first connecting portion 24, and the first protruding portion 25 protrudes from the first connecting portion 24 in a direction perpendicular to the height direction of the filter core 2.

[0034] In some embodiments, the filter element 2 further comprises a filter screen 26, the filter screen 26 is at least partially sleeved outside the support 21, for example, sleeved outside the first body part 22, the filter screen 26 is located between the support 21 and the housing 3; or, the filter screen 26 is located inside the support 21, for example, located inside the first body part 22, the support 21 is at least partially located between the filter screen 26 and the housing 3. The support 21 supports the filter screen 26 and maintains the shape of the filter screen 26. For example, the filter part 23 of the support 21 supports the filter screen 26, the filter part 23 is cylindrical, thereby maintaining the filter screen 26 in a cylindrical shape, and the first protrusion 25 can limit the relative displacement of the filter screen 26 relative to the support 21 in the height direction of the filter element 2. In some embodiments, the first body part 22 is cylindrical. In some embodiments, the support 21 is a plastic piece or a metal piece, and the filter screen 26 is a plastic piece, a textile piece, or a metal piece. All through holes 210 of the support 21 are covered by the filter screen 26. The mesh number of the filter screen 26 can be selected according to actual filtering needs, for example, 30-180 mesh, and specifically selected as 100 mesh, 75 mesh, 50 mesh, 30 mesh, etc.

[0035] In some embodiments, the mounting part 11 comprises a first mounting part 111, the filter element 2 is fixedly connected or limitingly connected with the first mounting part 111, and in the height direction of the filter element 2, the filter part 23 is away from the first mounting part 111 relative to the first connecting part 24. In some embodiments, the height direction of the filter element 2 is the same as the thickness direction of the flow channel integrated piece 1.

[0036] In some embodiments, the flow channel 12 comprises a first flow channel 121, the first mounting part 111 comprises a first side wall 112, the first opening 1031 penetrates through the first side wall 112, and the first opening 1031 communicates with the first flow channel 121.

[0037] In some embodiments, the filter element 2 has a first inner cavity 221, and the first inner cavity 221 at least partially forms the first filter cavity 103. In some embodiments, the first inner cavity 221 has a first opening 222, and in the height direction of the filter element 2, the first opening 222 is away from the first flow channel 121 relative to the first opening 1031.

[0038] In some embodiments, a plane perpendicular to the thickness direction of the flow channel integrated piece 1 is defined as a projection plane, along the thickness direction of the flow channel integrated piece 1, the wall corresponding to the first port 222 or the wall surrounding the first port 222 is orthographically projected on the projection plane as a first projection, the wall corresponding to the first opening 1031 or the wall surrounding the first opening 1031 is orthographically projected on the projection plane as a second projection, and the second projection is at least partially located within the first projection. In some embodiments, the flow area of the first opening 1031 is smaller than the flow area of the first port 222.

[0039] In some embodiments, the first mounting portion 111 further comprises a first protruding portion 113, the first mounting portion 111 has a first mounting cavity 114, the first protruding portion 113 and the first side wall 112 are located on the periphery of the first mounting cavity 114, along the thickness direction of the flow channel integrated piece 1, the first mounting cavity 114 and the first flow channel 121 are located on the two sides of the first side wall 112 respectively, and the first mounting cavity 114 and the first flow channel 121 are in communication with the first opening 1031. For example Figures 8-10 As shown, when the filter element 2 is combined with the first mounting portion 111, along the thickness direction of the flow channel integrated piece 1, the first opening 1031 is located between the first flow channel 121 and the first mounting cavity 114. When the filter element 2 is separated from the first mounting portion 111, the first flow channel 121 and the first filter cavity 103 are in communication with the first opening 1031. The first opening 1031 serves as the inlet or outlet of the first filter cavity 103.

[0040] In some embodiments, the first mounting portion 111 has a clamping groove capable of cooperating with the first protruding portion 25. When the first protruding portion 25 cooperates with the clamping groove, the first protruding portion 25 is limited in the clamping groove, limiting the relative displacement of the filter element 2 and the first mounting portion 111 in the height direction of the filter element 2, thereby realizing the limiting connection between the filter element 2 and the first mounting portion 111.

[0041] In some embodiments, the first mounting portion 111 comprises a first side wall 112 and a first protruding portion 113, the first side wall 112 is connected with the first protruding portion 113, along the thickness direction of the flow channel integrated piece 1, the first protruding portion 113 protrudes from the first side wall 112, and the first protruding portion 113 is located on one side of the first side wall 112. The first mounting portion 111 has a first mounting cavity 114, and the first side wall 112 and the first protruding portion 113 are located on the periphery of the first mounting cavity 114. For example Figures 8-10As shown, along the thickness direction of the flow channel assembly 1, the filter element 2 is at least partially located at the same side of the first side wall 112 as the first protrusion 113, and the clamping groove is arranged on the first protrusion 113. Specifically, the first protrusion 113 has an inner side and an outer side, and the inner side is closer to the first mounting cavity 114 than the outer side. In some embodiments, the clamping groove is recessed from the inner side to the inside of the first protrusion 113, and the first protruding portion 25 is away from the first body portion 22 relative to the first filter cavity 103. When the filter element 2 is connected to the first mounting portion 111 in a limiting manner, the first connecting portion 24 is at least partially located in the first mounting cavity 114, and the first protruding portion 25 is located in the clamping groove. In other embodiments, the clamping groove is recessed from the outer side to the inside of the first protrusion 113, and the first protruding portion 25 extends from the first body portion 22 to the direction close to the first filter cavity 103. When the filter element 2 is connected to the first mounting portion 111 in a limiting manner, the first connecting portion 24 is at least partially sleeved outside the first protrusion 113, and the first protruding portion 25 is located in the clamping groove.

[0042] In addition to the cooperation between the clamping groove and the first protruding portion 25, the filter element 2 and the first mounting portion 111 can also be connected in other ways. For example, the first protruding portion 25 of the filter element 2 is away from the first filter cavity 103 relative to the first body portion 22, the first protrusion 113 has a free end, the first protruding portion 25 abuts against the free end of the first protrusion 113, and the first protruding portion 25 and the free end of the first protrusion 113 are fixedly connected to a connecting member, such as a screw. In some embodiments, along the height direction of the filter element 2, the filter screen 26 is away from the first protrusion 113 relative to the first protruding portion 25.

[0043] In some embodiments, the filter element 2 is detachably connected with the first mounting portion 111. In this way, replacement of the filter element 2 is facilitated. Specifically, the filter element 2 and the first mounting portion 111 have a first state and a second state, when the filter element 2 and the first mounting portion 111 are in the first state, the filter element 2 is fixedly connected or limitingly connected with the first mounting portion 111, when the filter element 2 and the first mounting portion 111 are in the second state, the filter element 2 is separated from the first mounting portion 111. The filter element 2 and the first mounting portion 111 can be switched from the first state to the second state, and can also be switched from the second state to the first state. For example, the first protrusion 113 has a free end, the clamping groove includes a first clamping groove and a second clamping groove, the first clamping groove and the second clamping groove are in communication. Along the height direction of the first protrusion 113, the first clamping groove is located between the free end and the first side wall 112, and the first clamping groove extends along the circumferential direction of the first protrusion 113; the second clamping groove has a slot, and the slot is located at the free end of the first protrusion 113. When connecting the filter element 2 and the first mounting portion 111, first, along the height direction of the first protrusion 113, the first protruding portion 25 is clamped into the second clamping groove from the slot, and then the filter element 2 is rotated relative to the first protrusion 113 so that the first protruding portion 25 enters the second clamping groove; when disassembling the filter element 2 and the first mounting portion 111, first, the filter element 2 is rotated relative to the first protrusion 113 so that the first protruding portion 25 enters the second clamping groove, and then the first protruding portion 25 is pulled out of the second clamping groove along the height direction of the first protrusion 113. In other embodiments, the first protruding portion 25 and the free end of the first protrusion 113 are connected by a connecting piece, for example, by a bolt connection, and the detachable connection between the filter element 2 and the first mounting portion 111 can also be achieved.

[0044] Of course, in other embodiments, the filter element 2 and the first mounting portion 111 can be fixedly connected by means of gluing or welding.

[0045] In some embodiments, the filter element 2 is sealingly connected with the first mounting portion 111. Specifically, the first connecting portion 24 is sealingly connected with the first protruding portion 113. Specifically, the thermal management assembly 100 comprises a first sealing member 27 clamped between the first connecting portion 24 and the first protruding portion 113, and the first connecting portion 24 is sealingly connected with the first protruding portion 113 through the first sealing member 27. The first connecting portion 24 has an inner surface and an outer surface, and the inner surface is closer to the first filter cavity 103 than the outer surface. In some embodiments, the first connecting portion 24 has a first recess 241 formed by recessing inward from the outer surface of the first connecting portion 24, and a portion of the first sealing member 27 is located in the first recess 241. The first recess 241 is used to limit the displacement of the first sealing member 27. When the filter element 2 is connected with the first mounting portion 111, along the height direction of the first protruding portion 113, the first recess 241 is closer to the first side wall 112 than the first protruding portion 25, and the first sealing member 27 is closer to the first side wall 112 than the first protruding portion 25. In other embodiments, a recess for accommodating or limiting the first sealing member 27 can also be provided on the first protruding portion 113. Specifically, in the case that the first connecting portion 24 is at least partially located in the first mounting cavity 114, the recess for accommodating or limiting the first sealing member 27 is formed by recessing inward from the inner side of the first protruding portion 113 to the interior of the first protruding portion 113; in the case that the second connecting portion 35 is at least partially sleeved outside the first protruding portion 113, the recess for accommodating or limiting the first sealing member 27 is formed by recessing inward from the outer side of the first protruding portion 113 to the interior of the first protruding portion 113.

[0046] In some embodiments, the housing 3 is sealingly connected with the mounting portion 11. In some embodiments, the housing 3 is detachably connected with the mounting portion 11. Detachable connection means that the two can be switched from a combined state to a separated state, and also can be switched from a separated state to a combined state.

[0047] In some embodiments, the mounting portion 11 comprises a second mounting portion 115 located at the periphery of the first mounting portion 111, and the housing 3 is fixedly connected or limitingly connected with the second mounting portion 115, and the housing 3 is sealingly connected with the second mounting portion 115, for example Figures 1-4 as shown.

The sleeve portion 34 is at least partially sleeved outside the filter element 2, specifically, the sleeve portion 34 is at least partially sleeved outside the filter portion 23; the second connecting portion 35 is connected with the second mounting portion 115. In some embodiments, the height direction of the shell 3, the height direction of the filter element 2 and the thickness direction of the flow channel integrated piece 1 are in the same direction.

In other embodiments, the second opening 1041 is arranged on the shell 3, for example, arranged on the sleeve portion 34, as shown Figure 16 .

[0050] In some embodiments, the flow channel integrated piece 1 comprises a first flow channel portion 13 and a second flow channel portion 14, the first flow channel portion 13 is used to form a first flow channel 121, the first flow channel 121 is directly in communication with the first opening 1031, and the second flow channel portion 14 is used to form a second flow channel 122, the second flow channel 122 is directly in communication with the second opening 1041; along the thickness direction of the flow channel integrated piece 1, the filter element 2 and the first flow channel portion 13 are respectively located on both sides of the first mounting portion 111, the shell 3 and the second flow channel portion 14 are respectively located on both sides of the second mounting portion 115, and the first flow channel portion 13 is at least partially located inside the second flow channel portion 14, or in other words, the first flow channel portion 13 is at least partially located in the second flow channel 122, for example Figure 11 and Figure 12 as shown.

[0051] In some embodiments, the second inner cavity 32 has a second opening 33, and along the height direction of the shell 3, the second opening 33 is away from the second flow channel 122 relative to the second opening 1041.

[0052] In some embodiments, the second side wall 116 is located at the periphery of the first opening 1031, and the second opening 1041 is located at the periphery of the first opening 1031.
