That is, the battery cooling circuit and the motor cooling circuit radiate and cool the coolant through the cooler 8 and the radiator 5, respectively. Under this operating condition, the heat that battery 7 during operation produced is big, and the coolant liquid that circulates through radiator 5 can't satisfy the heat dissipation demand of battery 7, needs to start independent cooler 8 and carries out independent heat dissipation cooling to the battery return circuit and handle.

As shown in fig. 11 and 12, when the valve body 2 is rotated to the third operating position, that is, the valve body 2 can communicate the first through hole 11 and the fifth through hole 15 with the third flow passage 25, the second through hole 12 and the fourth through hole 14 with the second flow passage 24, and the third through hole 13 with the first flow passage 23.

The third flow channel 25 can communicate the first through hole 11 with the fifth through hole 15, so that the water outlet pipe of the battery 7 is directly communicated with the communication cavity 19; the second flow passage 24 is capable of communicating the second through hole 12 with the fourth through hole 14 so that the outlet pipe of the motor 4 communicates with the inlet pipe of the cooler 8. That is, when the battery cooling circuit is self-circulated through the communication chamber 19, the motor cooling circuit uses the cooler 8 to perform heat dissipation and temperature reduction.

As shown in fig. 13 and 14, when the valve body 2 is rotated to the fourth operating position, that is, the valve body 2 can communicate the first through hole 11 and the fifth through hole 15 with the first flow channel 23, the second through hole 12 and the third through hole 13 with the second flow channel 24, and the fourth through hole 14 with the third flow channel 25.

The first flow channel 23 can communicate the first through hole 11 with the fifth through hole 15, so that the water outlet pipe of the battery 7 is directly communicated with the communication cavity 19; the second flow passage 24 can communicate the second through hole 12 and the third through hole 13 to communicate the outlet pipe of the motor 4 with the inlet pipe of the radiator 5.

That is, in this state, the cooler 8 is not needed in the self-circulation circuit of the battery 7 for a while, which means that the temperature of the environment in which the battery 7 is used is low, and the heat pump heating mode needs to be started to ensure that the battery 7 can be in a good use state. The circuit of the motor 4 is independent of the battery self-circulation circuit, and the two circuits are in independent and mutually independent states.

As shown in fig. 15 and 16, when the valve body 2 is rotated to the fifth operating position, that is, the valve body 2 can communicate the first through hole 11, the second through hole 12, and the fourth through hole 14 with the second flow passage 24, the third through hole 13 with the third flow passage 25, and the fifth through hole 15 with the first flow passage 23.

The second flow channel 24 is communicated with the first through hole 11 and the fourth through hole 14, so that the water outlet pipe of the battery 7 is communicated with the water inlet pipe of the cooler 8; the second through hole 12 and the fourth through hole 14 are communicated so that the water outlet pipe of the motor 4 is communicated with the water inlet pipe of the cooler 8.

That is to say, the circulating water of the water outlet pipe of the motor 4 participates in the battery cooling circuit, and when the environment of the battery 7 is in a low temperature state, in order to ensure the normal working state of the battery 7, the water at the water outlet pipe of the motor 4 is directly led into the battery cooling circuit, so as to improve the temperature of the circulating water of the battery cooling circuit and ensure the normal working of the battery 7 in a low temperature environment.

As shown in fig. 17 and 18, when the valve body 2 is rotated to the sixth operating position, that is, the valve body 2 can communicate the first through hole 11, the second through hole 12, and the fifth through hole 15 with the first flow passage 23, the third through hole 13 with the second flow passage 24, and the fourth through hole 14 with the third flow passage 25.

The first flow channel 23 can communicate the first through hole 11 with the fifth through hole 15, so that the water outlet pipe of the battery 7 is communicated with the communication cavity 19; the second through hole 12 and the fifth through hole 15 are communicated so that the water outlet pipe of the motor 4 is communicated with the communication chamber 19. In this state, in the present invention, the working position is left set for extended use.

It should be noted that the working position of the valve core 2 is not limited to the above situation, and according to the actual situation, 6 or 7 through holes may be provided on the housing 1, or the valve core 2 is provided with more than 3 flow channels, so that more communication situations can be combined between the flow channels of the valve core 2 and the through holes to adapt to the constantly changing cooling system, and such adjustment and change of the number of the flow channels of the valve core 2 and the through holes of the housing 1 do not depart from the principle and scope of the present invention, and should be limited within the protection scope of the present invention.

Preferably, as shown in fig. 2 and 6, the communication chamber 19 is provided with a buffer chamber 191, which protrudes in a direction away from the second chamber 17, at a position communicating with the second chamber 17.

Illustratively, as shown in fig. 2 and 6, the communication chamber 19 is provided with two buffer chambers 191 on the housing 1 of the present invention, the two buffer chambers 191 are respectively opposite to the two second chambers 17, that is, the communication chamber 19 is at a position communicated with the second chambers 17, and the buffer chambers 191 are convexly provided in a direction away from the second chambers 17. It should be noted that, when the water pump rotates at a high speed, water flows to the cavity of the water pump through the water inlet at a high speed, at this time, a negative pressure of the water flow is formed at the position, the negative pressure of the water flow can deform the shell 1 communicated with the cavity 19, so that the water backflow speed is slowed, the water flow in the loop generates a higher negative pressure, the smoothness of water circulation is affected, and the safety and smoothness of the return water in the loop are ensured by the two buffer cavities 191.

Finally, the invention also provides a cooling system and a vehicle, comprising the valve device.

So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
