摘要： A thermal management system and a method of operating thereof includes a housing body having a first broad surface and an opposing second broad surface and may extend between a first end and a second end. The housing body defines plural passages disposed between the first and second broad surfaces. The plural passages extend in one or more orthogonal directions between the first and second ends of the body. An inlet conduit is fluidly coupled with a first passage of the plural passages via an inlet structure that defines an inlet of the housing body, and directs a fluid into the first passage of the plural passages. An outlet conduit is fluidly coupled with a second passage of the plural passages via an outlet structure that defines an outlet of the housing body, and directs the fluid out of the second passage of the plural passages.

摘要： A battery that includes collectors with tabs that are wide with respect to the area of the collector. The wide tabs present a low electrical and thermal resistance to improve the flow of current and/or heat to and from the collector thereby improving electrical and thermal performance of the battery. The battery further includes terminals with a channel that supports the flow of medium (e.g., liquid) to heat and/or cool the battery. The terminals may include fins or pins to increase the surface area of the terminal to improve thermal transfer to and from the battery and collectors of the battery. The batteries may be formed into a battery module that includes a system for monitoring and regulating the temperature of the batteries of the module.

摘要： A valve includes a housing having a housing cavity and at least two housing openings. A valve body is rotatably provided in the housing cavity and includes a valve body top portion, a valve body bottom portion and a valve body sidewall. The valve body sidewall has an upper valve body sidewall and a lower valve body sidewall which are connected to each other. An outer surface of the upper valve body sidewall is a partial cylindrical surface, and an outer surface of the lower valve body sidewall is shaped to have a gradually decreasing diameter in a direction from top to bottom. A seal is provided on the valve body sidewall and the seal is configured to match with the housing to enable the valve body sidewall to close at least one of the housing openings.
