[0048] It should be noted that Figures 1 to 12 They are all for illustration only and are not drawn in proportion, and should not be used as a limitation on the actual protection scope of the present invention.

[0049] Figure 1 Schematic diagram of a thermal management component in an embodiment of the present invention. The thermal management component 9 includes an expansion valve 91, a heat exchanger 92, a fluid guiding device 90 and an adapter 93. The fluid F used for heat exchange is a refrigerant in this embodiment. The refrigerant enters the thermal management component 9 through a channel of the expansion valve 91 and is throttled, then flows into the heat exchanger 92 through the fluid guiding device 90 and the adapter 93, and flows out of the heat exchanger 92 after heat exchange inside the heat exchanger 92. The refrigerant flowing out of the heat exchanger 92 flows out of the thermal management component 9 through the adapter 93, the fluid guiding device 90 and another channel of the expansion valve 91 in turn.

[0050] The heat exchanger 92 may be 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 a groove, and the upper plate 921 is welded to the lower plate 922, and a heat exchange channel suitable for the flow of heat exchange fluid is formed at the channel. A plurality of through holes 921a connected to the heat exchange channel are provided on the upper plate 921 to allow the heat exchange fluid to enter and exit the heat exchanger 92.

[0051] In an embodiment not shown in the figure, the heat exchanger 92 may also be a fin-tube heat exchanger. The fluid F used for heat exchange may not be a refrigerant, for example, it may be water, and accordingly, the thermal management component may not include the expansion valve 91 .

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

[0053] Since the fluid guiding device 90 has a third opening 90c, a fourth opening 90d and a fifth opening 90e which are interconnected through the intermediate cavity 90f in addition to the first opening 90a and the second opening 90b, a plurality of different flow channels which pass through the intermediate cavity 90f and penetrate the fluid guiding device 90 can be formed by a combination of any at least two of the third opening 90c, the fourth opening 90d and the fifth opening 90e, so that the fluid guiding device 90 reduces the number of openings while meeting different requirements for guiding the fluid F. Therefore, the fluid guiding device 90 provided by the present invention has the advantage of a simple structure.

[0054] The combination of the third opening 90c, the fourth opening 90d and the fifth opening 90e includes: Figure 2A , 3 As shown in FIGS. 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 such a combination, the fluid F flows into the fluid guiding device 90 from the third opening 90c and the fourth opening 90d, merges in the middle cavity 90f, and then flows out of the fluid guiding device 90 from the fifth opening 90e.

[0055] In other combinations, the flow direction of the fluid F may also be reversed. For example, the fifth opening 90e is the inlet, and the fluid F flows into the fluid guiding device 90 from the fifth opening 90e, is split in the middle 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 openings among the third opening 90c, the fourth opening 90d and the fifth opening 90e may be selected for the flow of the fluid F, and such selection is arbitrary. For example, the third opening 90c may be blocked, and the fluid F may only be allowed to pass through the fluid guiding device 90 through the fourth opening 90d and the fifth opening 90e; or the fifth opening 90e may be blocked, and the fluid F may only be allowed to pass through the fluid guiding device 90 through the third opening 90c and the fourth opening 90d; or the fourth opening 90d may be blocked, and the fluid F may only be allowed to pass through the fluid guiding device 90 through the third opening 90c and the fifth opening 90e.

[0057] In the above combination, if Figure 2A , 3 As shown in FIGS. 5A, 5B, 7 and 9, the first opening 90a and the fifth opening 90e may be arranged such that one of them is the inlet of the fluid guiding device 90 and the other is the outlet of the fluid guiding device 90, so that the fluid F at the first opening 90a and the fifth opening 90e has opposite flow directions and is suitable for being respectively connected with the two channels of the expansion valve 91. Correspondingly, the third opening 90c and the fourth opening 90d are both the outlet or the inlet 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 Fig. 9 In the illustrated embodiment, the second opening 90 b is the outlet of the fluid guiding device 90 , which is communicated with the through hole 921 a serving as the inlet of the heat exchanger 92 ; the third opening 90 c and the fourth opening 90 d are the inlets of the fluid guiding device 90 , which are communicated with the through hole 921 a serving as the outlet of the heat exchanger 92 .

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

[0060] In a more specific embodiment, Figure 2A , 2B , 2C, 3 and Figure 7 , 8As shown in FIGS. 9 and 10 , the fluid guiding device 90 includes a block 900. The block 900 preferably has six surfaces in space, each of which faces 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 a middle cavity 90f, a first opening 90a and a fifth opening 90e. The middle cavity 90f is arranged inside the block 900. 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 the following: Figure 2A , 7 The first opening 90a and the fifth opening 90e are formed on the protruding portion shown in the figure. Such a design allows the first opening 90a and the fifth opening 90e to be located on the same side of the block 900, so as to be suitable for connection with 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 an embodiment not shown in the figure, the first opening 90 a and the fifth opening 90 e may also be located on the outside of the block 900 , for example, on the side facing the first surface 900 a .

[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; Figure 2A As shown, the third opening 90 c , the fourth opening 90 d , and the second opening 90 b are located on the second surface 900 b 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 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 surfaces of the block 900 that are perpendicular to each other in space.

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

[0066] refer to Figure 3 , 5B The fluid guiding device 90 has a main flow channel 1, a first flow section 2, a second flow section 3 and a third flow section 4; wherein the main flow channel 1 connects the first opening 90a and the second opening 90b, and is not connected to the middle cavity 90f; the first flow section 2 connects and connects the third opening 90c and the middle cavity 90f respectively; the second flow section 3 connects and connects the fourth opening 90d and the middle cavity 90f respectively; the third flow section 4 connects and connects the fifth opening 90e and the middle cavity 90f respectively. This design makes the structure of the fluid guiding device 90 compact, and the middle cavity 90f and the third opening 90c, the fourth opening 90d and the second opening 90b are all formed on the block 900, and there is no need to design additional pipelines connecting the middle cavity 90f and 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 port section 11 and a sub-port section 12 that are connected and communicated with each other, wherein the sub-port section 12 is connected and communicated with the first opening 90a, and the main port section 11 is connected and communicated with the second opening 90b; the first flow section 2 includes a first port section 21 and a first communicating section 22, and the first port section 21 is connected and communicated with the third opening 90c; the second flow section 3 includes a second port section 31 and a second communicating section 32, and the second port section 31 is connected and communicated with the fourth opening 90d; the first communicating section 22 is connected and communicated with the first port section 21 and the middle cavity 90f respectively; the second communicating section 32 is connected and communicated with the second port section 31 and the middle cavity 90f respectively.

[0068] refer to Figure 2C , 3The main opening section 11, the second opening 90b, the third opening 90c, the fourth opening 90d, the first opening section 21, the first connecting section 22, the second opening section 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. Such a design enables the openings and internal pipelines 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 cross section AA may be parallel to the center lines of the main mouth section 11 , the first mouth section 21 , the first connecting section 22 , the second mouth section 31 , and the second connecting section 32 , respectively.

[0070] Furthermore, if Figure 2C , 3 As shown, the first cross section AA coincides with the center lines of the main mouth section 11, the first mouth section 21, the first connecting section 22, the second mouth section 31 and the second connecting section 32; accordingly, the main mouth section 11, the second opening 90b, the third opening 90c, the fourth opening 90d, the first mouth section 21, the first connecting section 22, the second mouth section 31, the second connecting section 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 auxiliary 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 flow guiding device 90; the two parts may 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 cross section BB of the flow guiding device 90; the two parts may be two equal parts.

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

[0074] Continue to refer Figure 3 and Fig. 9, the flow paths of the fluid F in the first flow segment 2 and the second flow segment 3 are equal. The flow path refers to the distance that the fluid F flows in the corresponding flow segment, and in this embodiment, it refers to the distance from the middle cavity 90f to the corresponding opening. Such a design allows the pressure loss of the fluid F flowing in the first flow segment 2 and the second flow segment 3 to tend to be equal. To achieve equal flow paths, the first flow segment 2 and the second flow segment 3 can be symmetrically distributed on both sides of the middle cavity 90f. More specifically, the second cross section CC divides the middle cavity 90f into two equal parts, and the first flow segment 2 and the second flow segment 3 are symmetrical about the second cross section CC.

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