Water-cooled plate assembly, water cooling system, battery and its housing, and power-consuming device

Abstract

A water-cooled plate arrangement comprising: a accordion tube plate in which several cooling channels are formed extending along a longitudinal direction of the accordion tube plate and arranged parallel along a transverse direction of the accordion tube plate to allow the flow of coolant; a first flow collector arranged at a first end of the accordion tube plate in the longitudinal direction and forming a first flow collector chamber communicating with an end connection of several cooling channels, the first flow collector forming a first liquid inlet and a first liquid outlet on both sides of the accordion tube plate in the thickness direction, through which the coolant can flow into and out of the first flow collector chamber;and a second flow collector arranged at a second end of the accordion tube plate opposite the first end in the longitudinal direction, forming a second flow collector chamber which communicates with another end connection of several cooling channels, wherein the second flow collector forms a second liquid inlet and a second liquid outlet on both sides of the accordion tube plate in the thickness direction, through which the coolant can flow into and out of the second flow collector chamber.
