Abstract: A temperature control system. The temperature control system includes a plurality of liquid pipelines and a multi-port valve. The multi-port valve includes a valve body and a valve core. The valve body has a mounting cavity, and the valve core is mounted in the mounting cavity. The valve body includes a body and a block-shaped additional portion, the mounting cavity is located on the body, and the block-shaped additional portion is attached to at least a part of a side wall of the body. The valve body includes a plurality of vias, and each via penetrates the block-shaped additional portion and a corresponding side wall of the body. Each liquid pipeline is configured to communicate with one via, there is a battery pack on at least one liquid pipeline, and the temperature control system is configured to control a temperature of the battery pack.

Abstract: A bidirectional energy storage device for a joint includes: a sleeve comprising an open end and an opposite, closed end; an elastic member attached to the sleeve; a sliding member slidably arranged at the open end of the sleeve, wherein opposite ends of the elastic member are respectively in contact with the closed end of the sleeve and the sliding member; a first telescopic link comprising a first end pivotally connected to the sliding member and an opposite, second end; and a second telescopic link comprising a first end pivotally connected to the sliding member and a second end. The second ends of the first telescopic link and the second telescopic link are pivotally connected to a rotating member at an end of the joint, and the first telescopic link and the second telescopic link are to extend and retract to drive the sliding member to side along the sleeve.

Abstract: A cooling system includes a first circulation pipeline unit and a second circulation pipeline unit that are configured to circulate a cooling medium. The first circulation pipeline unit includes a first water supply pipe group and a first water return pipe group that are connected to each other. The second circulation pipeline unit includes a second water supply pipe group and a second water return pipe group that are connected to each other. A first end of the first water supply pipe group and a first end of the first water return pipe group each are provided with a first expansion interface.

Abstract: A heat exchange plate which includes: a base board, where the base board includes a first edge along a first direction and a second edge along a second direction, and the first direction and the second direction are different directions; first flow guiders, where the first flow guiders are disposed on the base board, and are configured to guide flowing of air flows, where a plurality of the first flow guiders are arranged along the first direction at intervals into one column, and a plurality of columns of the first flow guiders are arranged along the second direction at intervals; and supporting structures, where the supporting structures are disposed on the base board, the supporting structures extend along the first direction, and the supporting structures and each column of the first flow guiders are arranged alternately along the second direction at intervals.
