For fuel vehicles, functional areas such as engine blocks, turbochargers, transmissions and passenger compartments also have a clear need for temperature and active management. A thermal management module formed by integrating a water valve or a plurality of water valves is arranged between the circulation loops as a device for controlling the flow direction or the flow rate of a medium.
At present, because the areas of the vehicle needing heat management are numerous, a plurality of water valves and actuators are usually needed to be matched to complete the control purpose, and the water valves are connected through pipelines, so that the pipelines are complex, the number of interfaces is large, the occupied space is large, the cost is high, and the like. If integrate a plurality of water valves into thermal management module (partial design also with synchronous integration such as water pump, fluid infusion kettle, liquid temperature sensor), can save auxiliary part such as partial pipeline, joint to make whole collaborative management ability stronger, nevertheless there are some not enoughly in current thermal management module:
1. a plurality of water valves are assembled in an integral shell in a structural form, but actuators for driving the water valves to operate still operate independently and drive a water valve core independently, and management logic is also designed independently aiming at each actuator and a water valve core flow passage;
2. a plurality of water valve cores are axially integrated by a part of thermal management modules (the shape is similar to a gourd string), so that one actuator and the same rotating shaft can be used for integrally rotating, but the angle positions of two groups of valve cores are strongly correlated, the flexibility of circulation control is greatly reduced, and only the flow channel form of a specific working condition and structure can be met.
3. The partial heat management module arranges a plurality of water valve cores on the same plane, gears are arranged on the valve cores to be meshed with each other, when one actuator is used for driving one valve core, other valve cores driven by meshing rotate synchronously in a linkage manner, but because the meshing state of the gears among the valve cores is fixed, the combination mode which can be realized by a flow passage in the valve core is less, and the medium flowing mode which can be realized is also less.

If the actuator drives the driving valve core 4 to rotate 90 degrees in the counterclockwise direction, namely, the driving valve core reaches the position of 180 degrees absolutely, in the process of rotation, because a gap exists between the driving step groups of the driving valve core 3 and the driven valve core 3 in the counterclockwise direction, the driving step groups are disengaged, the driven valve core 3 can keep still at the position of 270 degrees absolutely, when the driving valve core 4 completes 90 degrees rotation and reaches the position of 180 degrees absolutely, the driving step groups just contact in the counterclockwise direction, and the clockwise side is disengaged to form a gap, at this time, the driven valve core 3 and the driven valve core 3 complete the integral angle dislocation, as shown in fig. 12 and 13. At the moment, the first pipeline and the second pipeline are communicated through a flow passage B of the active valve core 4, the third pipeline and the fourth pipeline are communicated through a flow passage A of the active valve core 4, the sixth pipeline and the seventh pipeline are communicated through a flow passage C of the driven valve core 3, and other pipelines are closed, so that a fifth working condition is realized.

At the moment, the first pipeline and the fourth pipeline are communicated through a flow passage A of the active valve core 4, the second pipeline and the third pipeline are communicated through a flow passage B of the active valve core 4, the seventh pipeline and the eighth pipeline are communicated through a flow passage C of the driven valve core 3, and other pipelines are closed, so that the sixth working condition is realized.
