Abstract: A fluid control assembly and a thermal management system are provided. The fluid control assembly comprises valve parts, a connecting member, and a flow passage plate, portions of the valve parts are located in mounting chambers of the connecting member, the valve parts are connected to the connecting member, the connecting member is connected to the flow passage plate, the flow passage plate comprises a first plate and a second plate, the first plate and/or the second plate forms grooves or orifices of passages of the flow passage plate, the first plate and the second plate are fitted with each other to form at least some of the passages of the flow passage plate, and the valve parts can be communicated or not in communication with one, or two, or more of the passages of the flow passage plate.

Abstract: A fluid management device includes a control assembly, at least two block portions, and at least two valve core assemblies. The at least two block portions are hermetically connected to a same control assembly. The valve core assemblies are electrically connected to the control assembly. Each block portion includes a body portion. The body portion defines a mounting channel. A portion of the valve core assembly is located in an inner cavity of the control assembly, and another portion is located in the mounting channel. A gap is formed between two adjacent body portions for separating the body portions so as to reduce the possibility of heat transfer, thereby reducing harmful heat loss of the fluid management device.

Abstract: A fluid management apparatus and a thermal management system are provided. The fluid management apparatus includes a connector and a fluid control portion. The connector has a first accommodating cavity which accommodates the fluid control portion, an opening of the first accommodating cavity is located on a first side portion, at least part of the wall of the first side portion is perpendicular to a first surface, and projections of sub-channels located on the connector on the first surface do not overlap.
