[0031] The flow channels are arranged in a staggered manner, making rational use of the internal space of the block 100. Each flow channel is designed as a straight hole, which is easy to process. Moreover, a fluid control device that meets the flow channel requirements can be manufactured without process holes.

[0032] Furthermore, in the embodiments described herein, the block 100 is an integral structure (integrated herein means not joined by welding, gluing, or the like), which can minimize leakage points in the fluid control device. However, this does not preclude the block 100 from being formed by welding or other means, such as combining two or more parts, for example, two cubes or two cuboids, or a cube and a cuboid, or two or more parts of regular or irregular shapes. All of these fall within the scope of the block of the present application, as, compared to designs with multiple pipe connections, this can still reduce leakage in the entire fluid control device.

[0033] In the fluid control device of this embodiment, the flow channel design of the block 100 eliminates the need for additional process holes, facilitates processing, and reduces leakage risks, that is, reduces leakage problems caused by process holes or pipe connections.

[0034] The vehicle thermal management system includes a compressor 30 , a first heat exchanger 20 , an intermediate heat exchanger 10 , a second heat exchanger 50 , a battery cooler 60 , a gas cooler 40 , and the fluid control device of the present application.

[0035] The fluid control device's first port 01 is connected to the outlet of the compressor 30, the second port 02 is connected to the inlet of the first heat exchanger 20, the third port 03 is connected to the inlet of the gas cooler 40, the fourth port 04 is connected to the outlet of the second heat exchanger 50, the fifth port 05 is connected to the outlet of the gas cooler 40, the sixth port 06 is connected to the inlet of the intermediate heat exchanger 10, the seventh port 07 is connected to the inlet of the second heat exchanger 50, the eighth port 08 is connected to the inlet of the battery cooler 60, and the ninth port is connected to the outlet of the intermediate heat exchanger 10. The vehicle thermal management system can achieve four operating modes.

[0036] The aforementioned fluid control device and vehicle thermal management system effectively reduce the number of pipe connections in the system, reduce leakage points, and have a high degree of device and system integration.

[0037] 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.

[0038] The vehicle thermal management system can achieve four different operating modes, meeting the system's multifunctional requirements. Furthermore, the application of the fluid control device of the present application reduces the number of piping connections in the system, facilitates assembly, and reduces leak points.

[0039] The fluid control device and vehicle thermal management system of the present application have a high degree of integration and a compact structure. They are not only easy to install, but also, compared with pipeline connections, the flow channels are arranged inside the block device, which can reduce leakage of the fluid control device.

[0040] It should be noted that the above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. 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.
