Detailed implementation manners

[0016] Now, specific embodiments will be described in detail with reference to the accompanying drawings. For a full understanding of the present invention, numerous specific details are mentioned in the following detailed description. However, those skilled in the art should understand that the specific components, devices, and features illustrated in the drawings and described herein are merely exemplary and should not be considered as limiting.

[0017] Refer to Figures 1 - 5 , this embodiment provides a thermal management component, especially for the thermal management system of a vehicle. Specifically, it can be used on the water side of the thermal management system, or the working medium passing through the housing is coolant. Of course, the working medium passing through the housing can also be refrigerant, which will be described in detail below.

[0018] As Figure 1As shown, this embodiment discloses a thermal management component, which is characterized by including a first housing 1 and a second housing 2. The first housing 1 and the second housing 2 are fixedly connected or limit-connected. The thermal management component has a first channel 10 and a second channel 20. The first channel 10 communicates the chamber of the first housing 1 with the chamber of the second housing 2, and the second channel 20 communicates the chamber of the first housing 1 with the chamber of the second housing 2. The first housing 1 and the second housing 2 can be one of a water kettle, a valve housing, a heat exchanger, or a flow channel plate. Furthermore, the chambers of the first housing 1 and the second housing 2 can be one of a liquid storage chamber, a valve chamber, a heat exchange channel, or a flow channel. Specifically, the first housing 1 has a first chamber 1' and a third chamber 3', the second housing 2 has a second chamber 2' and a fourth chamber 4'. The first channel 10 communicates with the first chamber 1' of the first housing 1, the first channel 10 communicates with the second chamber 2' of the second housing 2, the second channel 20 communicates with the third chamber 3' of the first housing 1, and the second channel 20 communicates with the fourth chamber 4' of the second housing 2. In this embodiment, in order to facilitate the design of the sealing structure size, the extending direction of the wall of the first channel 10 is parallel or tends to be parallel to the extending direction of the wall of the second channel 20. Of course, there can also be a situation where the extending direction of the wall of the first channel 10 is inconsistent with the extending direction of the wall of the second channel 20.

[0019] The thermal management component includes a first seal 100 and a second seal 200. The first seal 100 is circumferentially arranged along the first channel 10. Along the axial direction of the first channel 10, the second seal 200 is circumferentially arranged along the second channel 20. At least one of the first seal 100 and the second seal 200 axially abuts between the first housing 1 and the second housing 2 along the first channel 10 or the second channel 20 respectively. That is, at the first channel 10 or the second channel 20, at least one place seals the leakage point of the first channel 10 by means of end face sealing. The thermal management component includes at most one set of limiting components 3 to limit the relative position of the first housing 1 and the second housing 2 along the radial direction of the first channel 10 or the second channel 20. Specifically, both ends of one of the first seal 100 and the second seal 200 axially abut the first housing 1 and the second housing 2 respectively along the axial direction of the first channel 10. The thermal management component includes one set of limiting components 3 to limit the relative position of the first housing 1 and the second housing 2 along the radial direction of the second channel 20; or, both ends of one of the first seal 100 and the second seal 200 axially abut the first housing 1 and the second housing 2 respectively along the axial direction of the second channel 20. The thermal management component includes one set of limiting components 3 to limit the relative position of the first housing 1 and the second housing 2 along the radial direction of the first channel 10; or, both ends of the first seal 100 axially abut the first housing 1 and the second housing 2 respectively along the axial direction of the first channel 10, and both ends of the second seal 200 axially abut the first housing 1 and the second housing 2 respectively along the axial direction of the second channel 20. The thermal management component does not have a limiting component 3 for limiting the relative position of the first housing 1 and the second housing 2 along the radial direction of the first channel 10 or the second channel 20. Or, both the first channel 10 and the second channel 20 adopt the end face sealing method. One of the two seals is radially limited by the limiting component, or there is no limiting component 3 radially limiting the two seals. It also includes that one of the first channel 10 and the second channel 20 adopts the end face sealing method, and the other channel adopts the radial sealing method. The limiting component 3 limits the positions of the first housing 1 and the second housing 2 along the radial direction of this channel. It should be emphasized that the position of the limiting component does not limit the sealing structure at the first channel 10 or the second channel 20, and can also be located at other positions of the first housing 1 and the second housing 2 except the two channels. Additionally, it should be noted that the axial direction of the first channel 10 or the second channel 20 refers to the direction perpendicular to the flow cross-section of the channel, and the radial direction of the first channel 10 or the second channel 20 refers to the direction from the center of the flow cross-section of the channel to the edge of the flow cross-section. Therefore, the above "axial" and "radial" do not limit the cross-sectional shape of the channel, that is, the cross-sectional shapes of the first channel 10 and the second channel 20 are not limited to be circular.

[0020] For the traditional method of using radial seals at both channels, it is necessary to consider the position dimensions of the shaft-hole fits at both places to ensure uniform compression of the seals at each place and prevent leakage due to insufficient compression at a certain circumferential position of the seal at one place caused by the position dimensions of the two shafts or two holes. This sealing method has much stricter requirements for the dimensions of the sealing place. If the housing is a plastic part, the plastic part has a large deformation, and the strict dimension requirements will lead to quality problems of the product, resulting in poor sealing performance of the thermal management component. In addition, in other traditional methods, for structures with multiple seals, especially two seals, double seals are used at each seal position, namely radial seal and end face seal, to avoid the failure of one of the seals. This requires adding seals and increases the cost.

[0021] Compared with the above two traditional sealing methods, in this embodiment, two different sealing methods are adopted at the two sealing positions. One uses the end face sealing method and the other uses the radial sealing method. This can weaken the limitation of the radial dimensions of the two sealing structures, ensure that the two sealing structures do not affect each other, and both sealing structures can be adjusted in position, which is beneficial to improving the sealing performance of each of the two sealing structures and the sealing performance of the thermal management component. In addition, the requirement for the dimensional machining accuracy of the two sealing structures is relaxed, thereby reducing the manufacturing cost of the thermal management component. Moreover, compared with the traditional double-sealing method, the number of seals is reduced, which also reduces the manufacturing cost of the thermal management component.

[0022] Reference Figures 1 - 2 Referring to

[0023] Further, in this embodiment, for the limiting method of the first limiting member 12 and the second limiting member 22, refer to Figure 2, the first limiting member 12 and the first housing 1 are of an integral structure. The first limiting member 12 includes a convex portion 121. Along the axial direction of the second channel 20, the convex portion 121 protrudes from the first housing 1 towards the second housing 2. The second limiting member 22 includes a hole portion 221. At least a part of the convex portion 121 is located in the cavity of the hole portion 221. The convex portion 121 includes a positioning section 1211. The hole portion 221 has a cavity wall 2210. The outer peripheral wall of the positioning section 1211 abuts against or has a gap with the cavity wall 2210. Along the radial direction of the second channel 20, the cavity wall 2210 limits the positioning section 1211. Specifically, when the positioning section 1211 and the hole portion 221 are in a clearance fit, there is a gap between the outer peripheral wall of the positioning section 1211 and the cavity wall 2210, but this gap is a gap that can ensure the radial limitation between the positioning section 1211 and the hole portion 221, and this gap can be almost ignored; when the positioning section 1211 and the hole portion 221 are in an interference fit or a transition fit, the outer peripheral wall of the positioning section 1211 abuts against the cavity wall 2210. In other embodiments, the positions of the convex portion 121 and the hole portion 221 can be interchanged, that is, the convex portion 121 can be located on the second housing 2 and the hole portion 221 can be located on the first housing 1, and the limiting function can also be achieved, which will not be elaborated here.

[0024] Further, referring to Figure 5 , for the convenience of installing the second seal 200, the convex portion 121 includes an installation section 1212. The outer peripheral wall of the installation section 1212 is closer to the axis of the second channel 20 than the outer peripheral wall of the positioning section 1211. The outer peripheral wall of the installation section 1212 is recessed towards the axis of the second channel 20 relative to the outer peripheral wall of the positioning section 1211. Along the radial direction of the second channel 20, there is a first gap 220 between the outer peripheral wall of the installation section 1212 and the cavity wall 2210. In this embodiment, the outer peripheral wall of the installation section 1212 extends from the positioning section to the end of the convex portion 121, which is convenient for integrally forming the convex portion and the first housing and for mold release. Of course, in other embodiments, the outer peripheral wall of the installation section 1212 does not have to extend to the end of the convex portion 121, that is, the first gap 220 can also be a groove. The second seal 200 is located in the first gap 220, and the second seal 200 abuts against the outer peripheral wall of the installation section 1212 and the cavity wall 2210.

[0025] Further, according to the above embodiments, there is a set of limiting components 3 in the thermal management component to limit the relative position of the first housing 1 and the second housing 2 in the radial direction of the second channel 20. Further, there will be no radial limit on the first housing 1 and the second housing 2 at the first channel 10, and the leakage point at the first channel 10 is sealed by an end face sealing method. Preferably, the thermal management component includes a first abutting wall 110 and a second abutting wall 210. The first abutting wall 110 is located on the first housing 1, and the second abutting wall 210 is located on the second housing 2. The first channel 10 includes a first sub-channel 101 and a second sub-channel 102. The first sub-channel 101 is communicated with the second sub-channel 102. The channel opening of the first sub-channel 101 close to the second housing 2 is located on the first abutting wall 110, and the channel opening of the second sub-channel 102 close to the first housing 1 is located on the second abutting wall 210. Along the axial direction of the first channel 10, one side portion of the first seal 100 abuts against the first abutting wall 110, and the other side portion of the first seal 100 abuts against the second abutting wall 210. It should be emphasized that the shapes of the first abutting wall 110 and the second abutting wall 210 in this embodiment are not limited to planes. The above-mentioned first abutting wall 110 and second abutting wall 210 represent the regional wall surfaces on the first housing 1 and the second housing 2 that are oppositely arranged at the first channel 10. The shapes of these regional wall surfaces include planes, curved surfaces, and stepped surfaces.

[0026] Further, in this embodiment, referring to Figure 2 and Figure 4 , in order to streamline the structure, the first abutting wall 110 includes a flat straight surface 111, and the second housing 2 has a groove 2110. The groove 2110 has an opening facing the first housing 1 at the second abutting wall 210. A part of the first seal 100 is located in the groove 2110. Along the axial direction of the first channel 10, one side portion of the first seal 100 abuts against the flat straight surface 111, and the other side portion of the first seal 100 abuts against the bottom wall of the groove 2110. In other embodiments, the flat straight surface 111 and the groove 2110 can be interchanged, that is, the second abutting wall 210 includes a flat straight surface 111, and the first housing 1 has a groove 2110, which can achieve the end face sealing function and will not be elaborated here.

[0027] Further, in this embodiment, the second abutting wall 210 includes a connecting surface 211. The groove 2110 is recessed relative to the connecting surface 211 in a direction away from the first abutting wall 110. The flat surface 111 abuts against the connecting surface 211 or has a gap. In this embodiment, the first abutting wall 110 and the second abutting wall 210 abut against each other through the flat surface 111 and the connecting surface 211 to achieve position limitation along the axial direction of the first channel 10. In other embodiments, the position limitation of the first abutting wall 110 and the second abutting wall 210 along the axial direction of the first channel 10 can be restricted by limiting structures at other positions of the first abutting wall 110 and the second abutting wall 210. Even the axial limiting structure can be provided on the first housing 1 and the second housing 2, away from the first abutting wall 110 and the second abutting wall 210. Additionally, in this embodiment, along the axial direction of the first channel 10, the flat surface 111 is located at the end of the first abutting wall 110, and the connecting surface 211 is located at the end of the second abutting wall 210. That is, along the radial direction of the first channel 10, the projection of the first abutting wall 110 does not overlap with the projection of the second abutting wall 210. In this way, there is no restriction between the first abutting wall 110 and the second abutting wall 210 along the radial direction of the first channel 10, which is beneficial to adjusting the relative positions of the first housing 1 and the second housing 2 to meet the relative positions of the first limiting member 12 and the second limiting member 22, thereby improving the sealing performance of the sealing structure at the second channel 20, and the sealing performance of the sealing structure at the first channel 10 is not affected.

[0028] In other embodiments, the sealing structure at the first channel 10 can also be similar to the sealing structure of the second channel 20, that is, there are also convex portions and hole portions at the first channel 10, but there is no restriction on the convex portions and the hole portions along the radial direction of the first channel 10. There is a stepped portion in the hole portion, and along the axial direction of the first channel 10, the first seal 100 abuts between the convex portion and the stepped portion of the hole portion.

[0029] Reference Figure 1 、 Figure 2 、 Figure 6 and Figure 7 , in this embodiment, the first housing 1 has a liquid storage portion 13, the liquid storage portion 13 has a liquid storage cavity 130, the second housing 2 has a flow channel portion 23, the flow channel portion 23 has a first flow channel 231 and a second flow channel 232. Specifically, the liquid storage cavity 130 includes a first chamber 1' and a third chamber 3', the first chamber 1' and the third chamber 3' are in fluid communication, the second chamber 2' includes the first flow channel 231, the fourth chamber 4' includes the second flow channel 232, the first channel 10 connects the liquid storage cavity 130 and the first flow channel 231, the second channel 20 connects the liquid storage cavity 130 and the second flow channel 232. Of course, it can also be that the first chamber 1' and the third chamber 3' are fluid-isolated, that is, the liquid storage cavity 130 includes two independent chambers. Specifically, in this embodiment, the first housing 1 is a partial housing of a kettle, and the second housing 2 is a partial housing of a flow channel plate.

[0030] Reference Figure 6 and Figure 7 In this embodiment, the first housing 1 has a plurality of first mounting holes 14 with openings facing the second housing 2. The second housing 2 has second mounting holes 24 corresponding to the first mounting holes 14. The second mounting holes 24 are through holes. The screw is at least partially located in the second mounting hole 24, and the screw fixedly connects the first housing 1 and the second housing 2. In this embodiment, the screw functions as a fixed connection. The size of the second mounting hole 24 needs to be slightly larger than the outer diameter of the screw, that is, there is a gap between the outer peripheral wall of the screw and the cavity wall of the second mounting hole 24. This is done to facilitate adjusting the relative positions of the first housing 1 and the second housing 2 to ensure the radial sealing performance at the second passage 20, that is, to ensure that the relative positions of the first limiting member 12 and the second limiting member 22 are not affected by the screw connection, and to ensure that the compression amount of the second seal 200 between the first limiting member 12 and the second limiting member 22 is uniform.

[0031] Furthermore, with reference to Figure 2 、 Figure 6 and Figure 7 The thermal management component includes a first connection portion 11 and a second connection portion 21. The first connection portion 11 is located on the first housing 1. The first abutting wall 110 is located on the first connection portion 11. The second abutting wall 210 is located on the second connection portion 21. The second connection portion 21 is located on the second housing 2. The wall of the first passage 10 is located between the first connection portion 11 and the second connection portion 21. A plurality of groups of first mounting holes 14 and second mounting holes 24 are arranged on the outer periphery of the wall of the first passage 10. The screw fixedly connects the first connection portion 11 and the second connection portion 21. The first connection portion 11 and the second connection portion 21 compress the first seal 100. This ensures that the circumferential compression amount of the first seal 100 in the first passage 10 is uniform and improves the sealing performance of the sealing structure at the first passage 10.

Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the core idea of the present application. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
