DETAILED DESCRIPTION

[0023] The features and exemplary embodiments of various aspects of the present invention are described below. To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below with reference to the accompanying drawings and specific embodiments. In this document, relational terms such as "first" and "second" are used merely to distinguish one component from another with the same name, and do not necessarily require or imply any actual relationship or order between these components.

[0024] An embodiment of the present invention provides a flow channel assembly that can be applied to a vehicle thermal management system or an air-conditioning system, and in particular, can be applied to a coolant circulation loop of a vehicle, and of course can also be applied to a refrigerant circulation loop of a vehicle.

[0025] Specifically, refer to Figures 1 to 3The embodiment of the present application provides a flow channel assembly 01, comprising a flow channel portion 100 and a first interface portion 200. The first interface portion 200 is fixedly connected to the flow channel portion 100 or has an integral structure. Specifically, the first interface portion 200 and the flow channel portion 100 are welded, riveted, or screwed, or the first interface portion 200 and the flow channel portion 100 are integrally forged, cast, or injection molded. The flow channel portion 100 has a plurality of flow channels 1, and the first interface portion 200 has a plurality of interfaces 2. The interfaces 2 are connected to thermal management components in the vehicle thermal management system to form a partial thermal management loop.

[0026] The flow channel 1 includes a first flow channel 11 and a second flow channel 12. The flow channel in which the temperature of the fluid in the flow channel is in the first temperature range is defined as the first flow channel 11, and the flow channel in which the temperature of the fluid in the flow channel is in the second temperature range is defined as the second flow channel 12. There is a temperature difference between the first temperature range and the second temperature range. In the embodiment of the present application, the first temperature range is lower or higher than the second temperature range as a whole. In the present embodiment, the first flow channel 11 is the coolant inlet flow channel or the coolant outlet flow channel of the evaporator in the thermal management system, and the first temperature range is generally 2°C-35°C. The second flow channel 12 is the coolant inlet flow channel or the coolant outlet flow channel of the water-cooled condenser in the thermal management system, and the second temperature range is generally 45°C-70°C. In other embodiments, the first flow channel 11 can also be the coolant inlet flow channel or the coolant outlet flow channel of the water-cooled condenser in the thermal management system, or in other words, the first flow channel 11 is used to connect the coolant channel of one of the evaporator and the condenser, and the second flow channel 12 A cooling liquid channel for connecting the evaporator and the condenser to each other, in this embodiment, the first flow channel 11 and the second flow channel 12 are both provided in plurality, the interface 2 includes a first interface 21 and a second interface 22, the first interface 21 is connected to the first flow channel 11, and the second interface 22 is connected to the second flow channel 12, wherein at least one first flow channel 11 is adjacent to at least one of the other first flow channels 11, that is, two or more first flow channels 11 are centrally arranged, preferably, each first interface 21 is adjacent to at least one of the other first interfaces 21, that is, multiple first interfaces 21 are centrally arranged in one area of the first interface portion 200, and the second interface 22 is arranged in other areas, each first flow channel 11 is adjacent to at least one of the other first flow channels 11, that is, multiple first flow channels 11 are centrally arranged in one area of the flow channel portion 100, and the second flow channel 12 is arranged in other areas. In this embodiment, the flow channels and interfaces in the same temperature range are centrally arranged, refer to Figure 12 Compared with the staggered arrangement of the first flow channel 11 in the first temperature range and the second flow channel 12 in the second temperature range, and compared with the staggered arrangement of the first interface 21 and the second interface 22 concentrated in the first interface part 200, the present application reduces the heat exchange area between the first flow channel 11 and the second flow channel 12, and reduces the heat exchange area between the first interface 21 and the second interface 22, thereby reducing harmful heat transfer in the flow channel assembly.

[0027] refer to Figures 1 to 3 In one embodiment of the present application, the normal direction of the extension plane of the flow channel portion 100 is defined as a first direction M. In addition, a second direction N and a third direction K are defined. The second direction N and the third direction K are perpendicular to each other. The second direction N and the third direction K constitute the extension plane of the flow channel portion 100. In this embodiment, the flow channel portion 100 is roughly rectangular plate-shaped. The first direction M is the thickness direction of the flow channel portion 100, the second direction N is the width direction of the flow channel portion 100, and the third direction K is the length direction of the flow channel portion 100. The second direction N is perpendicular to the first direction M, and the third direction K is perpendicular to the first direction M. Along the first direction M, the projection of the wall forming the first flow channel 11 is separated from the projection of the wall forming the second flow channel 12. The projection separation means that the projections do not overlap, or in other words, the projection of the wall forming the first flow channel 11 and the projection of the wall forming the second flow channel 12 are flat on the extension plane of the flow channel portion 100, and there is no overlap, and thus in the flow channel portion 100 thickness direction (first direction M), the heat exchange area between the first flow channel 11 and the second flow channel 12 is reduced, so that the second flow channel 12 has strong heat transfer only with the first flow channel 11 located at the edge among the multiple first flow channels 11, and the second flow channel 12 is far away from the other first flow channels 11 among the multiple first flow channels 11, thereby weakening the heat transfer between the second flow channel 12 and the other first flow channels 11 among the multiple first flow channels 11. In addition, the projection of the wall forming the first interface 21 is separated from the projection of the wall forming the second interface 22. Similarly, in the first direction M, the heat exchange area between the first interface 21 and the second interface 22 is reduced, so that the second interface 22 has strong heat transfer only with the first interface 21 located at the edge among the multiple first interfaces 21, and the second interface 22 is far away from the other first interfaces 21 among the multiple first interfaces 21, thereby weakening the heat transfer between the second interface 22 and the other first interfaces 21 among the multiple first interfaces 21.

[0028] Further, refer to Figures 1 to 4The first interface portion 200 includes a first wall 20, a first interface 21 and a second interface 22 both located on the first wall 20, and the first interface 21 and the second interface 22 are arranged side by side along the second direction N. In this embodiment, the plurality of first interfaces 21 and the plurality of second interfaces 22 are arranged linearly. Specifically, the centers of the first interfaces 21 and the second interfaces 22 are located on or close to the same straight line. The linear arrangement direction of the first interfaces 21 and the second interfaces 22 is the second direction N. Along the second direction N, the second interfaces 22 have strong heat transfer only with the first interfaces 21 located at the edge of the plurality of first interfaces 21, thereby reducing the heat transfer between the second interfaces 22 and the other first interfaces 21. The second interfaces 22 are preferably all located on the same side of the first interface 21 along the second direction N. In this way, strong heat transfer only occurs between the second interface 22 located at the edge and the first interface 21 located at the edge, while the other first interfaces 21 and the other second interfaces 22 are far apart, thereby reducing the heat transfer between them. Similarly, since the first flow channel 11 and the second flow channel 12 do not overlap in the first direction M, strong heat transfer only occurs between one second flow channel 12 located at the edge and one first flow channel 11 located at the edge. The distances between the other first flow channels 11 and the other second flow channels 12 are relatively large, which weakens the heat transfer between them. Of course, it is not necessary for all second interfaces 22 to be located on one side of the first interface 21. The second interfaces 22 can also be divided into two groups, located on both sides of the first interface 21 along the second direction N. In addition, the linear arrangement of multiple interfaces 2 facilitates the connection, installation, and maintenance between the first interface portion 200 and other components.

[0029] In one embodiment of the present application, in order to facilitate the arrangement of the thermal management components on the flow channel assembly, along the second direction N, the second interface 22 is located on both sides of the first interface 21. In addition, the first interface portion 200 is an integral structure with the flow channel portion 100. The first interface portion 200 and the flow channel portion 100 are integrally forged, cast or injection molded. The first interface portion 200 protrudes from the flow channel portion 100 along the first direction M. Along the third direction K, the first flow channel 11 and the second flow channel 12 are located on the same side of the interface 2. Specifically, with reference to Figure 3 In this embodiment, the first interface portion 200 is perpendicular or nearly perpendicular to the flow channel portion 100, the first wall surface 20 is parallel or nearly parallel to the extension plane of the flow channel portion 100, and the central axis direction of the first interface 21 and the second interface 22 is consistent with the first direction M.

[0030] refer to Figure 4 and Figure 6In combination with any of the above embodiments, in order to reduce heat transfer between the first flow channel 11 and the second flow channel 12, the flow channel assembly has an insulation groove 3, and the insulation groove 3 can be a cavity or a hollow portion, that is, the insulation groove 3 does not penetrate or penetrates the flow channel assembly. The insulation groove 3 is used to avoid direct solid heat exchange between the first flow channel 11 and the second flow channel 12. Specifically, the walls forming the insulation groove 3 include a first insulation wall 301 and a second insulation wall 302. The first insulation wall 301 is opposite to the second insulation wall 302. The insulation groove 3 is located on one side of the first insulation wall 301, and the first flow channel 11 is located on the other side of the first insulation wall 301. The insulation groove 3 is located on one side of the second insulation wall 302, and the second flow channel 12 is located on the other side of the second insulation wall 302. In this embodiment, since the second flow channels 12 located on both sides are shorter than the first flow channels 11 and occupy a smaller area on the flow channel portion 100, the thermal insulation groove 3 is L-shaped and semi-encloses the second flow channel 12, thereby reducing the heat transfer between the second flow channel 12 and other flow channels on the flow channel portion 100, thereby reducing harmful heat transfer in the flow channel assembly.

[0031] Further, refer to Figures 6 to 8 , not only is a heat insulation groove provided between the first flow channel 11 and the second flow channel 12 to reduce heat transfer, but a heat insulation groove is also provided between the first interface 21 and the second interface 22 to reduce heat transfer. In this embodiment, the flow channel assembly has a first channel 210 and a second channel 220. The axial direction of the first channel 210 and the axial direction of the second channel 220 are consistent with the first direction M. The first channel 210 connects the first interface 21 and the first flow channel 11, and the second channel 220 connects the second interface 22 and the second flow channel 12. The heat insulation groove 3 includes a first groove 31 and a second groove 32, which are perpendicular to the In the direction of the extension plane of the flow channel portion 100, the second groove 32 is close to the interface 2 relative to the first groove 31, the walls forming the first groove 31 include the first thermal insulation wall 301 and the second thermal insulation wall 302, and the walls forming the second groove 32 include the third thermal insulation wall 303 and the fourth thermal insulation wall 304, the third thermal insulation wall 303 is opposite to the fourth thermal insulation wall 304, the second groove 32 is located on one side of the third thermal insulation wall 303, the first channel 210 is located on the other side of the third thermal insulation wall 303, the second groove 32 is located on one side of the fourth thermal insulation wall 304, and the second channel 220 is located on the other side of the fourth thermal insulation wall 304. In this embodiment, in order to avoid other flow channels on the flow channel portion 100, the first groove 31 does not penetrate the flow channel portion 100. In order to avoid the end face seal of the interface 2 on the first wall, the second groove 32 does not penetrate the interface portion. Specifically, the wall forming the first groove also includes a stepped wall 305. The stepped wall 305 is parallel to the extension plane of the flow channel portion 100. Along the direction perpendicular to the extension plane of the flow channel portion 100 (the first direction M), the first groove 31 is located on one side of the stepped wall 305, and the second groove 32 is located on the other side of the stepped wall 305. Along the third direction K, the second groove 32 is closer to the interface 2 than the first groove 31.

[0032] Specifically, refer to Figure 1 、 Figures 9 to 11 The flow channel assembly includes a first heat exchanger interface portion 41 and a second heat exchanger interface portion 42. The first heat exchanger interface portion 41 has a first heat exchange interface 410, and the second heat exchanger interface portion 42 has a second heat exchange interface 420. One end of the first flow channel 11 is connected to the first heat exchange interface 410, and the other end of the first flow channel 11 is connected to the first interface 21. One end of the second flow channel 12 is connected to the second heat exchange interface 420, and the other end of the second flow channel 12 is connected to the second interface 22. In this embodiment, reference Figure 11 , a plurality of heat exchangers are connected to the flow channel assembly, namely the first heat exchanger 51, the second heat exchanger 52 and the third heat exchanger 53, the first heat exchange interface 410 is arranged in pairs, specifically two pairs, one pair of which is connected to the coolant inlet channel and the coolant outlet channel of the first heat exchanger 51, and the other pair is connected to the coolant inlet channel and the coolant outlet channel of the second heat exchanger 52, respectively. The first interface 21 is also arranged in pairs, specifically including a first coolant interface 21a, a second coolant interface 21a', a third coolant interface 21b and a fourth coolant interface 21b', wherein one of the first coolant interface 21a and the third coolant interface 21b is connected to the coolant inlet channel of the first heat exchanger 51 , the other connects to the coolant outlet channel of the first heat exchanger 51. One of the second coolant interface 21a' and the fourth coolant interface 21b' connects to the coolant inlet channel of the second heat exchanger 52, and the other connects to the coolant outlet channel of the second heat exchanger 52. The second heat exchange interfaces 420 are arranged in pairs, specifically a pair, each connecting to the coolant inlet channel and coolant outlet channel of the third heat exchanger 53. The second interfaces 22 are a pair, namely the fifth coolant interface 22a and the sixth coolant interface 22b. One of the fifth coolant interface 22a and the sixth coolant interface 22b connects to the coolant inlet channel of the third heat exchanger 53, and the other connects to the coolant outlet channel of the third heat exchanger 53. In this embodiment, the first heat exchanger 51 and the second heat exchanger 52 serve as evaporators in the thermal management system, and the third heat exchanger 53 serves as a water-cooled condenser.

[0033] Further, refer to Figure 5 、 Figures 9 to 11In this embodiment, to minimize the length of the multiple first flow channels 11 and second flow channels 12, multiple heat exchangers are arranged on both sides of the flow channel portion, close to the first interface portion. Furthermore, a third heat exchanger is arranged on the other side of the flow channel portion 100, opposite the first interface portion 200. This is to further shorten the length of the second flow channel 12 and reduce the risk of harmful heat transfer from the high-temperature fluid in the second flow channel 12 to other flow channels. Specifically, the first heat exchanger interface portion 41 is located on one side of the flow channel portion 100, the second heat exchanger interface portion 42 is located on the other side of the flow channel portion 100, and the second heat exchanger interface portion 2 is closer to the first interface portion 200 than the first heat exchanger interface portion 2.

[0034] In conjunction with any of the above embodiments, refer to Figure 5 、 Figure 6 、 Figure 9 and Figure 10 In order to facilitate the processing of the first flow channel 11 and the second flow channel 12 as well as the first channel 210 and the second channel 220, in this embodiment, the flow channel assembly includes a first plate body 71, a second plate body 72 and a third plate body 73. The second plate body 72 is specifically a flat plate with through holes and hollows. The first plate body 71 and the third plate body 73 are fixedly connected on both sides of the flat plate. Specifically, the second plate body 72 includes a first straight portion 721 and a second straight portion 722. The first straight portion 721 is opposite to the second straight portion 722. The first plate body 71 is fixedly connected to the first straight portion 721, and the third plate body 73 is fixedly connected to the second straight portion 722. The first interface portion 200 is located on the first plate body 71.

[0035] The walls forming the first flow channel 11 are located between the first plate 71 and the first straight portion 721. Specifically, the first plate 71 has a plurality of grooves and through-holes. The walls of the grooves are sealed to the first straight portion 721. The walls forming the first flow channel are located between the walls forming the grooves and the first straight portion. The walls of the first channel 210 and the second channel 220 are located between the walls forming the through-holes. The second flow channel 12 includes a first sub-segment 121 and a second sub-segment 122. The walls forming the first sub-segment 121 are located between the first plate 71 and the first straight portion 721. The walls forming the second sub-segment 122 are located between the third plate 73 and the second straight portion 722. The second plate 72 has a connecting hole 120. One end of the connecting hole 120 connects to the first sub-segment 121, and the other end connects to the second sub-segment 122. The second flow channel 12 is divided into two sections. Along the thickness direction of the flow channel portion 100, the first sub-segment 121 and the first flow channel 11 are at the same height, and the second sub-segment 122 and the first flow channel are at a different height. This arrangement can lengthen the distance between the second sub-segment 122 and the first flow channel 11, weaken the heat transfer between the second sub-segment 122 of the second flow channel 12 and the first flow channel 11, thereby weakening the harmful heat transfer in the flow channel assembly.

Specifically, in this embodiment, the third heat exchanger 53 serves as the condenser 02, the first heat exchanger 51 and the second heat exchanger 52 serve as the evaporator 03, the evaporator 03 has a first refrigerant channel 103 and a first coolant channel 203, the first refrigerant channel 103 can exchange heat with the first coolant channel 203, the condenser 02 has a second refrigerant channel 102 and a second coolant channel 202, the second refrigerant channel 102 can exchange heat with the second coolant channel 202; reference Figure 3 、 Figure 10 and Figure 11 In this embodiment, the first heat exchanger interface portion 41 also has a third heat exchange interface 411, and the second heat exchanger interface portion 42 also has a fourth heat exchange interface 421. The third heat exchange interface 411 is arranged in pairs, and is used to respectively connect the inlet and outlet of the first refrigerant channel 103 of the evaporator 03, and the fourth heat exchange interface 421 is arranged in pairs, and is used to respectively connect the inlet and outlet of the second refrigerant channel 102 of the condenser 02. In addition, the paired first heat exchange interfaces 410 are respectively connected to the inlet and outlet of the first coolant channel 203 of the evaporator 03, and the paired second heat exchange interfaces 420 are respectively connected to the inlet and outlet of the second coolant channel 202 of the condenser 02. It is understood that the first refrigerant channel 103 of the evaporator 03 circulates the low-temperature, low-pressure refrigerant after throttling in the thermal management system. Accordingly, the coolant temperature in the first coolant channel 203 that exchanges heat with it is relatively low, generally ranging from 2°C to 35°C. The second refrigerant channel 102 of the condenser 02 circulates the high-temperature, high-pressure refrigerant before throttling in the thermal management system. Accordingly, the coolant temperature in the second coolant channel 202 that exchanges heat with it is relatively high, generally ranging from 45°C to 70°C. In addition, it should be noted that Figure 11 The dotted lines in the middle represent the refrigerant channels and the coolant channels. They are only schematic diagrams, and the directions of the dotted lines do not represent the actual flow directions of the refrigerant and coolant.

[0037] The flow channel assembly 01 has a plurality of first flow channels 11 and a plurality of second flow channels 12. The first flow channels 11 communicate with one of the first coolant channel 203 and the second coolant channel 202, and the second flow channels 12 communicate with the other of the first coolant channel 203 and the second coolant channel 202. At least one first flow channel 11 is adjacent to at least one of the other first flow channels 11, that is, two or more first flow channels 11 are centrally arranged. Preferably, each first flow channel 11 is adjacent to at least one of the other first flow channels 11. In this embodiment, the first flow channel 11 communicates with the first coolant channel 203, and the second flow channel 12 communicates with the second coolant channel 202. Due to the large temperature difference between the fluid in the first coolant channel 203 and the fluid in the second coolant channel 202, strong heat exchange occurs between the first flow channel 11 and the second flow channel 12. This heat exchange affects the heat exchange efficiency of the heat exchange components (batteries, electric drives, etc.) in the thermal management system, resulting in harmful heat transfer. Therefore, arranging high-temperature or low-temperature coolant channels in a centralized manner can reduce heat exchange between channels with temperature differences, thereby reducing harmful heat transfer in the thermal management component.

[0038] In other embodiments, the thermal management component includes one of the evaporator 03 and the condenser 02, the first flow channel 11 connects the coolant channel of one of the evaporator 03 and the condenser 02, and the second flow channel 12 is used to connect the coolant channel of the other of the evaporator 03 and the condenser 02, wherein, used for connection means that the corresponding evaporator 03 or the condenser 02 is not directly located in the thermal management component of this embodiment, and the second flow channel 12 is only a section of the coolant inlet flow channel and the outlet flow channel of the heat exchanger. For example, the evaporator 03 is fixedly connected to the flow channel portion 100 of the flow channel component 01, and the condenser 02 is fixedly connected to other components on the vehicle. The coolant channel of the evaporator 03 is directly connected to the first flow channel 11, and the coolant channel of the condenser 02 is indirectly connected to the second flow channel 12.
