A multi-port valve includes a valve housing and a valve core. The valve housing comprises a cylindrical main body defining an inner cavity to rotatably accommodate the valve core and a plurality of ports in fluid communication with the inner cavity. The valve core defines a plurality of flow channels, each extending through a sidewall of the valve core to form two opposite open ends. The valve housing is provided with a guider passage, and the plurality of flow channels include a first flow channel, a second flow channel and a third flow channel. The multi-port valve is operable to be switched between a plurality of work modes in response to the valve core rotating to different positions relative to the valve housing. The first flow channel is connected in series with the second flow channel via the guider passage in response to a first work mode of the plurality of work modes. The first flow channel is connected in series with the third flow channel via the guider passage in response to a second work mode of the plurality of work modes.

Multi-port valve and thermal management system having multi-port valve

The patent discloses a thermal management system and a valve thereof. The valve comprises a valve house and a valve core that can be rotatably mounted in the valve house. A plurality of inner valve ports and a plurality of outer valve ports are defined in an axial end of the valve house. The inner valve ports and the outer valve ports are arranged at intervals along the circumference of valve house. the valve core defines a plurality of inner flow channels and a plurality of outer flow channels extending through one of axial ends of the valve core. the inner flow channels are located at a radial inner side of the outer flow channels and are not in communication with each other inside the valve core. The inner flow channels are corresponding to the inner valve ports. The outer flow channels are corresponding to the outer valve ports. In response to the valve core rotating to different positions relative to the valve house, the inner flow channels selectively communicate with different inner valve ports, and the outer flow channel selectively communicate with different outer valve ports.

Thermal management system and valve thereof

A multi-port valve includes a valve housing and a valve core. The valve housing includes a plurality of ports arranged in a circumferential direction. All the ports are grouped into at least two port groups. Each of the port groups includes a main port and a plurality of sub-ports. The valve core is rotatably mounted to the valve housing and defines at least two flow channels. The multi-port valve has a plurality of work modes in response to the valve core rotated as regard to the valve housing to different positions. In different work modes, each of said at least two flow channels is configured to selectively communicate one of the main ports with one of the sub-ports.
