The above interfaces are connected to the corresponding mounting holes through corresponding flow channels. In the block device of this scheme, each mounting hole can be used to connect with a valve unit or other units, and each flow channel is arranged in the block device without using pipeline connection. When applied to the system, after each interface is connected to the external component, the external component realizes communication between part or all of the flow channels through the flow channel inside the block 1. The degree of integration is high, and leakage caused by pipeline connection can be reduced.

[0030] The block device includes a first mounting hole 11, a second mounting hole 12 and a third mounting hole 13. In a further embodiment, the block 1 further includes a fourth mounting hole 14. The opening of the fourth mounting hole 14 is also located on the third wall surface C.

The fifth branch path 2071 extends from the seventh interface 107 into the block 1 until it intersects with the sixth branch path 2072 and is arranged parallel to the first branch path 2041. That is, the fifth branch path 2071 extends in the transverse direction of the block 1. The sixth branch path 2072 is arranged perpendicular to the fifth branch path 2071. The sixth branch path 2072 is arranged in the longitudinal direction of the block 1, and one end of the sixth branch path 2072 is connected to the fourth mounting hole 14. In the block 1, along the horizontal direction of the block 1, the sixth branch 2072 and the third branch 2042 are staggered, that is, the center lines of the two are not at equal distances from the third wall C, the sixth branch 2072 is closer to the third wall C than the third branch 2043, the eighth interface 108 is located on the fourth wall D like the fifth interface 105, the eighth flow channel 208 is arranged perpendicular to the first flow channel 201, the eighth flow channel 208 is a circular hole, and the eighth flow channel 208 extends from the eighth interface 108 into the block 1 to the first mounting hole 11.

[0032] The fourth mounting hole 14 can be connected to a valve unit or other units. The eighth interface 108 and the eighth flow channel 208 increase the application function of the block 1. When increasing the application function of the block 1, no pipelines or leakage points are added.

[0033] In a further solution, the block 1 also includes a fifth mounting hole 15, a ninth interface 109, and a ninth flow channel 209. The fifth mounting hole 15 is located between the first mounting hole 11 and the third mounting hole 13. The opening of the fifth mounting hole 15 is also located on the third wall C.

The sixth branch 2053 is a circular hole and is coaxially arranged with the fifth branch 2052, so that the second mounting hole is connected to the fifth interface 105, reducing flow resistance. The block 1 of this solution, when applied to a thermal management device, such as a vehicle thermal management system, can be combined with a corresponding valve unit to increase the working mode of the vehicle thermal management system without increasing the pipeline connection and the leakage points caused by the pipeline connection.

[0034] In a further embodiment, block 1 further includes a sixth mounting hole 16, with fourth mounting hole 14 located between second mounting hole 12 and sixth mounting hole 16. The opening of sixth mounting hole 16 is also located on third wall surface C. Second flow channel 202 further includes a seventh branch 2027 and an eighth branch 2028. Second mounting holes 12, fourth mounting hole 14, and third mounting hole 16 are arranged in a first row of units on block 1, while first mounting hole 11, fifth mounting hole 13, and third mounting hole 15 are arranged in a second row of units on block 1. The second flow channel is disposed in the space between the first and second rows of units, effectively utilizing the space within block 1 and making the flow channel arrangement within block 1 more compact and reducing the block size. Among them, one end of the seventh branch 2027 is connected to the sixth mounting hole 16, and the seventh branch 2027 extends from the sixth mounting hole along the horizontal direction of the block 1 into the block 1. The seventh branch 2027 is a circular hole, and its center line is parallel to the second branch 2022. The other end of the seventh branch 2027 intersects with the eighth branch 2028. The seventh flow channel 207 also includes a seventh branch 2073, which is coaxially arranged with the sixth branch 2072. One end of the seventh branch 2073 is connected to the fifth and sixth branches 2071 and the sixth branch 2072, and the other end is connected to the sixth mounting hole 16. That is, the fourth mounting hole 14 and the sixth mounting hole 16 are connected through the seventh flow channel 27.

[0035] The eighth branch 2028 is a circular hole, arranged parallel to the third branch 2043. One end intersects with the seventh branch 2027, and the other end intersects with the second branch 2022 and the third branch 2023, and is arranged coaxially with the first branch 2021. When applied to a thermal management device, such as a vehicle thermal management system, the block 1 of this solution, when combined with a corresponding valve unit, can increase the operating modes of the vehicle thermal management system without increasing the number of pipe connections and the leak points that come with them.

[0036] The openings of the first mounting hole 11, the second mounting hole 12, the third mounting hole 13, the fourth mounting hole 14, the fifth mounting hole 15 and the sixth mounting hole 16 are oriented in the same direction, which facilitates installation and is neatly arranged when connected to the valve unit or other units.

[0037] In this embodiment, as a specific example, the block 21 is generally a rectangular parallelepiped structure. The openings of the first mounting hole 11, the second mounting hole 12, the third mounting hole 151, the fourth mounting hole 14, the fifth mounting hole 13, and the sixth mounting hole 16 are all located on the same side of the block 21, which helps to improve the space utilization of the block 1.

[0038] Of course, the block 1 is not limited to the rectangular parallelepiped structure shown in the figure. In addition, in the embodiment given in this text, the block 1 is an integrated structure (integrated in this article means not spliced ​​by welding, bonding, etc.), which can minimize the leakage points of the fluid control device. However, this does not exclude the possibility that the block 1 is composed of two or more parts combined by welding or other means, for example, two cubes or two rectangular parallelepipeds or a cube combined with a rectangular parallelepiped, or more than two regular or irregular parts, all of which should fall within the scope of the block of this application, because, compared with the design of multiple pipe connections, this can still reduce the leakage of the block device.

[0039] The above-mentioned interfaces, when block 1 is specifically applied to the system, some serve as inlets, some as outlets, or some can serve as both inlets and outlets when the fluid flows in the reverse direction. This scheme does not impose any specific restrictions. The block device of this scheme can select an interface as an outlet or an inlet according to the structure of the block device and the system requirements when applied.

[0040] In the above description, each flow channel is a circular hole, and the cross-sectional wall of the flow channel is circular, but this is not a limitation on the shape of each flow channel, but is only an example of a specific embodiment.

[0041] The block device of the present application has flow channels arranged inside and has a compact structure. The flow channels are not connected by pipelines, which not only reduces the use of pipelines but also improves the leakage risks caused by the use of pipelines.

[0042] When the block device of the present application can be applied to a vehicle thermal management system, the vehicle thermal management system used includes a compressor 30, a first heat exchanger 20, an intermediate heat exchanger 10, a second heat exchanger 50, a battery cooler 60 and a gas cooler 40. The first interface 101 is connected to the outlet of the compressor 30, and the third interface 103 is connected to the inlet of the intermediate heat exchanger 10. The second interface 102 is connected to the inlet of the first heat exchanger 20, the fourth interface 104 is connected to the outlet of the second heat exchanger 50, the fifth interface 105 is connected to the outlet of the intermediate heat exchanger, and the sixth interface 106 is connected to the inlet of the second heat exchanger 50. The seventh interface 107 is connected to the outlet of the gas cooler 40, the eighth interface 108 is connected to the inlet of the gas cooler 40, and the ninth interface 109 is connected to the inlet of the battery cooler 60. This vehicle thermal management system effectively reduces the pipe connections in the system, reduces the leakage points, and has a high degree of device and system integration. The vehicle thermal management system realizes the connectivity of multiple channels when the block 1 does not use pipelines, and can realize multiple working modes of the vehicle thermal management system after cooperating with corresponding valve units or other units.

[0043] It should be noted that the description of the refrigerant flow path in the above-mentioned various working modes does not mean that the vehicle thermal management system only includes the above-mentioned components.

[0044] The above-mentioned vehicle thermal management system, due to the application of the block device of the present application, can meet the multifunctional requirements of the system, reduce the number of pipe connections in the system, facilitate assembly, and reduce leakage points.

[0045] The manufacturing method of the above block device is as follows:

[0046] A block device is prepared, and the prepared block device includes a block 1, which is an integral structure. The block blank is processed by casting or forging, and the first interface 101, the second interface 102, the third interface 103, the fourth interface 104, the fourth interface 105, the sixth interface 106, the seventh interface 107, the eighth interface 108, and the ninth interface 109 are processed on the block blank. The first mounting hole 11, the second mounting hole 12, the third mounting hole 151, the fourth mounting hole 14, the fifth mounting hole 13, and the sixth mounting hole 16. The prepared block device also includes the aforementioned flow channels. In the process of preparing the block 1, a number of process holes will be formed on the block 1. After the flow channel processing is completed, the process holes are sealed. The processing method of the above-mentioned flow channels and mounting holes can be a mechanical manufacturing method such as boring.

[0047] The first, second, and third interfaces 101, 102, and 103 all face the same direction. The fourth and seventh interfaces 104, 107, and fifth, sixth, eighth, and ninth interfaces 105, 106, 108, and 109 all face the same direction. This facilitates connection of compressors and other components when used in a vehicle thermal management system.

[0048] The block device manufactured by the manufacturing method has fewer leakage points and improved sealing performance.

[0049] The block device of the present application has a high degree of integration, the entire device has a compact structure, and the flow channel is arranged inside the block device, which can reduce leakage caused by the flow channel being connected through pipelines.

Those skilled in the art should understand that those skilled in the art can still modify, combine or make equivalent substitutions to the present invention, and all technical solutions and improvements that do not depart from the spirit and scope of the present invention should be included within the scope of the claims of this solution.
