Because the temperature sensing component is influenced by the temperature and changes, when the temperature sensing component senses that the temperature of the battery pack is small and the amplitude is high, but the temperature of the battery pack is not required to be reduced immediately, if the controlled valve is opened, unnecessary occupation of cooling liquid can exist, and the cooling speed of other battery packs needing to be cooled is reduced. Therefore, the design of a system for cooling only the battery pack with large temperature difference is very necessary.
In this embodiment, as shown in fig. 5, the wedge-shaped member is a right-angled triangular sheet metal, and the wedge-shaped member has a first right-angled side, a second right-angled side, and a hypotenuse; wherein the first right-angle edge is parallel to a first plane; the second right-angle side and the first fan-shaped piece do not generate acting force, and the oblique side and the second fan-shaped piece can contact and generate relative displacement; and satisfy, when the hypotenuse contacted with the second fan-shaped piece, the hypotenuse had the extrusion force with the second fan-shaped piece. When the battery package temperature is normal, the connecting block is located the one end that is close to liquid outlet channel, and when the temperature of battery package risees gradually, connecting block and connecting rod slowly move to the valve body direction at the spacing inslot, when connecting block 1232 removed to the valve body direction and pastes tight valve body, the connecting rod bore the pressure promotion wedge component of expansion end and moves to the valve body direction, and the card slot that reaches the wedge component is fixed with the edge buckle of second fan-shaped piece. When the connecting rod bears the pulling force that the movable end kept away from the valve body, the connecting piece takes place the displacement in spacing groove 1232 earlier, when the connecting piece contacted closely with the wedge component, the wedge component moved to keeping away from the valve body direction until not contacting with the second fan-shaped piece, under the effect of the power of torsional spring, the second fan-shaped piece got back to initial position.
In one embodiment, the distance from the locking slot 122 to the first right-angle edge is 1/4D-1/3D; and D is the length of the wedge-shaped component in the Y direction, and the maximum flow of the controlled valve can be controlled by controlling the position of the clamping groove.

The included angle between the two stress ends of the torsion spring and the circle center of the fixed disk is 360 degrees/n-160 degrees.
Because the fixed separation blade and the movable separation blade have certain thickness, when the wedge-shaped component directly moves towards the valve body direction, the valve body can be directly extruded with a high probability, and therefore the service life of the valve body is influenced.
In this embodiment, as shown in fig. 6, the second fan blade has a projection 3322 at the pushing position, which is located at the side of the second fan blade facing the outlet passage and the pushing position can be in contact with the wedge-shaped member; the convex block is triangular prism-shaped, the section of the convex block perpendicular to the side edges is acute-angled triangle-shaped, one side edge of the convex block is coincided with the edge of the second fan-shaped sheet, and one side face of the convex block is in contact with the second fan-shaped sheet. The wedge-shaped member is contacted with the convex block to generate extrusion force by arranging the convex block matched with the wedge-shaped member on the second fan-shaped piece, so that the movable blocking piece rotates, and the size of a gap between the second fan-shaped piece and the first fan-shaped piece is changed.
