[0047] The following discloses various embodiments or examples of the subject matter technical solutions. To simplify the disclosure, specific examples of the elements and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of protection of the present invention. For example, the distribution of the first feature and the second feature as described later in the specification can include an embodiment in which the first and second features are distributed in a direct connection, or an embodiment in which an additional feature is formed between the first and second features, so that the first and second features are not directly connected. In addition, reference numerals and / or letters may be repeated in different examples in these contents. This repetition is for brevity and clarity and does not in itself indicate the relationship between the various embodiments and / or structures to be discussed. Furthermore, when the first element is described in a manner connected or combined with the second element, the description includes embodiments in which the first and second elements are directly connected or combined with each other, as well as embodiments in which one or more other intervening elements are added to indirectly connect or combine the first and second elements with each other.

[0048] It is important to note that Figures 1 to 12 These are merely examples and are not drawn to scale, nor should they be construed as limiting the scope of protection of the present invention.

[0049] Figure 1 This is a schematic diagram of a thermal management assembly 9 according to one embodiment of the present invention. The thermal management assembly 9 includes an expansion valve 91, a heat exchanger 92, a fluid guiding device 90, and a connector 93. The fluid F used for heat exchange is a refrigerant in this embodiment. The refrigerant enters the thermal management assembly 9 through one channel of the expansion valve 91 and is throttled, then flows into the heat exchanger 92 through the fluid guiding device 90 and the connector 93, undergoes heat exchange inside the heat exchanger 92, and then flows out of the heat exchanger 92. The refrigerant exiting the heat exchanger 92 flows out of the thermal management assembly 9 in sequence through the connector 93, the fluid guiding device 90, and another channel of the expansion valve 91.

[0050] Heat exchanger 92 can be as follows Figure 1 , 9 The cooling plate shown includes an upper plate 921 and a lower plate 922. The lower plate 922 has a channel formed by grooves, and the upper plate 921 is welded to the lower plate 922, forming a heat exchange channel suitable for the flow of heat exchange fluid in the channel. The upper plate 921 has a plurality of through holes 921a communicating with the heat exchange channel to allow the heat exchange fluid to enter and exit the heat exchanger 92.

[0051] In embodiments not shown, heat exchanger 92 may also be a finned tube heat exchanger. The fluid F used for heat exchange may not be a refrigerant; for example, it may be water. Accordingly, the thermal management components may not include expansion valve 91.

[0052] like Figures 2A to 6B As shown, the fluid guiding device 90 has a first opening 90a and a second opening 90b, wherein the first opening 90a is connected to the second opening 90b to guide fluid F through the fluid guiding device 90; the fluid guiding device 90 also has a third opening 90c, a fourth opening 90d, an intermediate cavity 90f and a fifth opening 90e; the intermediate cavity 90f is connected to the third opening 90c, the fourth opening 90d and the fifth opening 90e respectively; wherein at least two of the third opening 90c, the fourth opening 90d and the fifth opening 90e are used to guide fluid F through the intermediate cavity 90f and through the fluid guiding device 90.

[0053] Because the fluid guiding device 90 has a third opening 90c, a fourth opening 90d, and a fifth opening 90e that are interconnected through an intermediate cavity 90f, in addition to the first opening 90a and the second opening 90b, multiple different flow channels penetrating the fluid guiding device 90 through the intermediate cavity 90f can be formed by combining any two of the third opening 90c, the fourth opening 90d, and the fifth opening 90e. This reduces the number of openings while still meeting the needs of different guided fluids F. Therefore, the fluid guiding device 90 provided by this invention has the advantage of simple structure.

[0054] The combinations of the third opening 90c, the fourth opening 90d, and the fifth opening 90e include: (e.g.) Figure 2A , 3 As shown in Figures 5A, 5B, 7, and 9, the third opening 90c and the fourth opening 90d are both inlets of the fluid guiding device 90, and the fifth opening 90e is the outlet of the fluid guiding device 90. In this combination, fluid F flows into the fluid guiding device 90 from the third opening 90c and the fourth opening 90d, merges in the intermediate cavity 90f, and then flows out of the fluid guiding device 90 from the fifth opening 90e.

[0055] In another combination, the flow direction of fluid F can also be reversed. For example, the fifth opening 90e is the inlet, and fluid F flows into the fluid guiding device 90 from the fifth opening 90e, and is split in the intermediate cavity 90f, and then flows out of the fluid guiding device 90 from the third opening 90c and the fourth opening 90d respectively.

[0056] In other combinations, only two of the third opening 90c, fourth opening 90d, and fifth opening 90e can be selected for the flow of fluid F; this selection is arbitrary. For example, the third opening 90c can be blocked, allowing fluid F to pass through the fluid guiding device 90 only through the fourth opening 90d and the fifth opening 90e; or the fifth opening 90e can be blocked, allowing fluid F to pass through the fluid guiding device 90 only through the third opening 90c and the fourth opening 90d; or the fourth opening 90d can be blocked, allowing fluid F to pass through the fluid guiding device 90 only through the third opening 90c and the fifth opening 90e.

[0057] In the above combinations, such as Figure 2A , 3 As shown in Figures 5A, 5B, 7, and 9, the first opening 90a and the fifth opening 90e can be configured such that one is the inlet of the fluid guiding device 90 and the other is the outlet of the fluid guiding device 90. This allows the fluid F at the first opening 90a and the fifth opening 90e to have opposite flow directions, thus facilitating communication with the two channels of the expansion valve 91 respectively. Correspondingly, the third opening 90c and the fourth opening 90d are both outlets or inlets of the fluid guiding device 90, and the flow direction of the fluid F at the third opening 90c and the fourth opening 90d is opposite to the flow direction of the fluid F at the second opening 90b.

[0058] exist Figure 9 In the embodiment shown, the second opening 90b is the outlet of the fluid guiding device 90, which is connected to the through hole 921a, which serves as the inlet of the heat exchanger 92; the third opening 90c and the fourth opening 90d are the inlets of the fluid guiding device 90, which are connected to the through hole 921a, which serves as the outlet of the heat exchanger 92.

[0059] In embodiments not shown in the accompanying drawings, the first opening 90a and the fifth opening 90e may also be configured as either the inlet or outlet of the fluid guiding device 90.

[0060] In a more specific embodiment, such as Figure 2A , 2B 2C, 3 and Figure 7 , 8As shown in Figures 9 and 10, the fluid guiding device 90 includes a block 900, which preferably has six surfaces in space, each surface facing one side of the block 900 in space; the block 900 may also be a spatial structure with more than six surfaces. The block 900 has an intermediate cavity 90f, a first opening 90a, and a fifth opening 90e; wherein the intermediate cavity 90f is disposed inside the block 900, as shown in Figures 9 and 10. Figure 2A , 7 As shown, the first opening 90a and the fifth opening 90e are located on the first surface 900a of the block 900. The first surface 900a may not be a plane and may include, for example, Figure 2A , 7 The protruding portion shown has a first opening 90a and a fifth opening 90e formed thereon. This design allows the first opening 90a and the fifth opening 90e to be located on the same side of the block 900, thus facilitating connection to the expansion valve 91 or an external pipeline. The expansion valve 91 can be directly mounted on the first surface 900a of the block 900.

[0061] In embodiments not illustrated, the first opening 90a and the fifth opening 90e may also be located on the outside of the block 900, for example, on the side facing the first surface 900a.

[0062] exist Figure 2A , 2B In the embodiments shown in 2C, 3, 4, 5A, 5B, 6A, and 6B, the block 900 further has a third opening 90c, a fourth opening 90d, and a second opening 90b; wherein, as Figure 2A As shown, the third opening 90c, the fourth opening 90d, and the second opening 90b are located on the second surface 900b of the block 900.

[0063] like Figure 7 As shown, the third opening 90c, the fourth opening 90d, and the second opening 90b are located on the outside of the block 900, for example, on the side facing the second surface 900b.

[0064] Continue to refer to Figure 2A The first surface 900a and the second surface 900b are two adjacent surfaces of the block 900. More specifically, the first surface 900a and the second surface 900b are two mutually perpendicular surfaces of the block 900 in space.

[0065] exist Figure 7 , 8In the embodiments shown in 9 and 10, the fluid guiding device 90 further includes a first tube 901, a second tube 902, and a third tube 903; one end of the first tube 901 has a second opening 90b, and the other end is connected to the block 900 and communicates with the first opening 90a; one end of the second tube 902 has a third opening 90c, and the other end is connected to the block 900 and communicates with the intermediate cavity 90f; one end of the third tube 903 has a fourth opening 90d, and the other end is connected to the block 900 and communicates with the intermediate cavity 90f. This design can reduce the volume of the block 900 and make the opening arrangement of the fluid guiding device 90 more flexible.

[0066] refer to Figure 3 , 5B The fluid guiding device 90 has a main channel 1, a first flow section 2, a second flow section 3, and a third flow section 4. The main channel 1 connects the first opening 90a and the second opening 90b, but does not connect to the intermediate cavity 90f. The first flow section 2 connects to the third opening 90c and the intermediate cavity 90f. The second flow section 3 connects to the fourth opening 90d and the intermediate cavity 90f. The third flow section 4 connects to the fifth opening 90e and the intermediate cavity 90f. This design makes the fluid guiding device 90 compact, as the intermediate cavity 90f, the third opening 90c, the fourth opening 90d, and the second opening 90b are all formed on the block 900, eliminating the need for additional piping connecting the intermediate cavity 90f to the third opening 90c, the fourth opening 90d, and the second opening 90b.

[0067] refer to Figure 2C , 3 The main flow channel 1 has a main inlet section 11 and a secondary inlet section 12 that are interconnected and connected. The secondary inlet section 12 is connected and connected to the first opening 90a, and the main inlet section 11 is connected and connected to the second opening 90b. The first flow section 2 includes a first inlet section 21 and a first connecting section 22. The first inlet section 21 is connected and connected to the third opening 90c. The second flow section 3 includes a second inlet section 31 and a second connecting section 32. The second inlet section 31 is connected and connected to the fourth opening 90d. The first connecting section 22 is connected and connected to the first inlet section 21 and the intermediate cavity 90f, respectively. The second connecting section 32 is connected and connected to the second inlet section 31 and the intermediate cavity 90f, respectively.

[0068] refer to Figure 2C , 3The main opening 11, the second opening 90b, the third opening 90c, the fourth opening 90d, the first opening 21, the first connecting section 22, the second opening 31, the second connecting section 32, and the intermediate cavity 90f are all divided into two parts by the first cross-section AA of the fluid guiding device 90. The first cross-section AA is a plane. This design allows the openings and internal pipes of the fluid guiding device 90 to be distributed on the first cross-section AA, thereby helping to reduce the thickness of the fluid guiding device 90 in the direction perpendicular to the first cross-section AA.

[0069] More specifically, the first section AA can be parallel to the center lines of the main segment 11, the first segment 21, the first connecting segment 22, the second segment 31, and the second connecting segment 32, respectively.

[0070] Furthermore, such as Figure 2C , 3 As shown, the first cross section AA coincides with the center lines of the main port segment 11, the first port segment 21, the first connecting segment 22, the second port segment 31, and the second connecting segment 32; correspondingly, the main port segment 11, the second opening 90b, the third opening 90c, the fourth opening 90d, the first port segment 21, the first connecting segment 22, the second port segment 31, the second connecting segment 32, and the intermediate cavity 90f are all divided into two equal parts by the first cross section AA of the fluid guiding device 90.

[0071] like Figure 5B As shown, the first opening 90a, the fifth opening 90e, the main opening section 11, the secondary opening section 12, the intermediate cavity 90f, and the third flow section 4 are all divided into two parts by the second cross section CC of the fluid guiding device 90; these two parts can be two equal parts.

[0072] like Figure 5A As shown, the fifth opening 90e, the third flow section 4, the intermediate cavity 90f, the first connecting section 22 and the second connecting section 32 are all divided into two parts by the third section BB of the fluid guiding device 90; these two parts can be two equal parts.

[0073] In the above embodiment, the second cross-section CC and the third cross-section BB are perpendicular to the first cross-section AA. The second cross-section CC and the third cross-section BB are perpendicular to each other. Both the second cross-section CC and the third cross-section BB are planes. The intermediate cavity 90f is located at the intersection of the first cross-section AA, the second cross-section CC, and the third cross-section BB. The center of the intermediate cavity 90f is the intersection of the first cross-section AA, the second cross-section CC, and the third cross-section BB.

[0074] Continue to refer to Figure 3 and Figure 9The flow path of fluid F is equal in the first flow section 2 and the second flow section 3. Flow path refers to the distance fluid F travels within a corresponding flow section; in this embodiment, it refers to the distance from the intermediate cavity 90f to the corresponding opening. This design ensures that the pressure loss experienced by fluid F flowing in the first flow section 2 and the second flow section 3 tends to be equal. To achieve equal flow paths, the first flow section 2 and the second flow section 3 can be symmetrically distributed on both sides of the intermediate cavity 90f. More specifically, the second cross-section CC divides the intermediate cavity 90f into two equal parts, and the first flow section 2 and the second flow section 3 are symmetrical about this second cross-section CC.

[0075] refer to Figure 3 In one specific embodiment, the main port segment 11 is parallel to the first port segment 21 and the second port segment 31; the first connecting segment 22 and the second connecting segment 32 extend along the same straight line LL, which may coincide with the centerline of the first connecting segment 22 and the second connecting segment 32; the first port segment 21 is perpendicular to the first connecting segment 22; and / or the second port segment 31 is perpendicular to the second connecting segment 32. The secondary port segment 12 is perpendicular to the main port segment 11; the secondary port segment 12 is parallel to the third flow segment 4; the third flow segment 4 is perpendicular to the first connecting segment 22 and the second connecting segment 32. These features, individually or in combination, make the structure of the block 900 compact.

[0076] Embodiments of the present invention also disclose a method for manufacturing a fluid guiding device 90, which includes a method for forming an intermediate cavity 90f inside a block 900, namely:

[0077] A first opening 90a is defined on block 900; the first opening 90a is related to the installation location of expansion valve 91 or the connection location of external pipeline. The first opening 90a can be marked in a three-dimensional drawing before the manufacturing process of block 900 begins.

[0078] A secondary opening segment 12, connecting to the first opening 90a, is machined inside the block 900; the machining process can be machining. The secondary opening segment 12 is shown... Figure 5B and Figure 12 middle.

[0079] A fifth opening 90e is defined on block 900; the fifth opening 90e is related to the installation location of expansion valve 91 or the connection location of external pipeline. The fifth opening 90e can be identified in the three-dimensional drawing before the manufacturing process of block 900 begins.

[0080] A third flow section 4, connecting to the fifth opening 90e, is machined inside the block 900; the machining process can be machining. The third flow section 4 is shown in... Figure 5A , Figure 5B , Figure 11 and Figure 12 middle.

[0081] Define process opening 5 on block 900; process opening 5 is displayed... Figure 2A , 3 5A, 6A, 6B, and Figure 11 In the process of manufacturing block 900, process opening 5 can be marked in a three-dimensional drawing before the manufacturing process of block 900 begins. Process opening 5 is preferably located on the third side 900c of block 900, which is adjacent to the first surface 900a and the second surface 900b respectively. Further, the first surface 900a, the second surface 900b and the third side 900c are perpendicular to each other.

[0082] A process channel 6, connecting the process opening 5, is machined inside the block 900, wherein the process channel 6 is connected to the third flow section 4 to form an intermediate cavity 90f. The machining process can be machining. The process channel 6 is shown in [the image / description]. Figure 3 , Figure 5A , Figure 6A , Figure 6B , Figure 11 In the middle. Furthermore, such as... Figure 11 As shown, process channel 6 can penetrate the block 900. Alternatively, as... Figure 3 As shown, the process channel 6 terminates inside the block 900 in the extending direction. The process channel 6 extends along a straight line LL inside the block 900.

[0083] like Figure 3 , 5B As shown, the manufacturing method of the fluid guiding device 90 includes defining a second opening 90b on a block 900; and machining a main opening 11 connecting the secondary opening 12 and the second opening 90b inside the block 900. The machining process can be machining. Before the manufacturing process of the block 900 begins, the second opening 90b can be marked on a three-dimensional drawing. The main opening 11 can be perpendicular to the secondary opening 12.

[0084] for Figure 2A , 3 The manufacturing method of the fluid guiding device, as shown in block 900, further includes,

[0085] The third opening 90c and the fourth opening 90d are determined on the block 900; the third opening 90c and the fourth opening 90d can be marked in the three-dimensional drawings before the manufacturing process of the block 900 begins.

[0086] A first segment 21 connecting the third opening 90c is machined inside the block 900.

[0087] A second segment 31 is machined inside the block 900 to connect to the fourth opening 90d; wherein the second segment 31 is parallel to the first segment 21 and parallel to the main segment 11.

[0088] During the processing of the process channel 6, the process channel 6 is first extended to connect with one of the first section 21 and the second section 31, then extended to connect with the third flow section 4 to form an intermediate cavity 90f, and then extended to connect with the other of the first section 21 and the second section 31; wherein, the extension direction of the process channel 6 is perpendicular to the second section 31, the first section 21 and the main section 11.

[0089] The process channel 6 has a first connecting section 22 that connects the first port section 21 and the intermediate cavity 90f, and a second connecting section 32 that connects the second port section 31 and the intermediate cavity 90f.
