Abstract: A multi-port valve includes a valve housing and a valve core. The valve housing is provided with a plurality of outer ports, at least part of which is arranged at an axial end of the valve housing. The valve core is provided with a plurality of inner ports, at least part of which is arranged at an axial end of the valve core. A plurality of flow channels extends through the valve core, whereas the flow channels are fluidly separated from one another inside the valve core. The plurality of the flow channels includes at least two cross-channels intersecting with each other in a projection plane perpendicular to a rotation axis of the valve core. Each of the flow channels communicates with two of the inner ports. At least part of the inner ports is aligned and communicated with the corresponding outer ports in response to the valve core rotating to a desired position as regarded to the valve housing.

Abstract: An actuator for a cooling fan module includes a controller, a first motor and a second motor. The controller includes a controlling unit configured to receive control commands, and a motor driving unit electrically connected to the controlling unit and powered by a DC power supply. The first motor is electrically connected to the motor driving unit. The second motor is connected in parallel to the first motor. The first motor and the second motor are synchronously driven and controlled by the controller.

Abstract: 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.
