COOLANT FLOW MANIFOLDS AND METHODS OF USE THEREOF

Methods, apparatuses, and vehicles are provided for liquid cooling a high voltage apparatus. The apparatuses include a body, a channel that defines a coiled flow path through the body, wherein the flow path is configured to receive a flow of coolant therethrough, wherein walls of the channel are formed of a low conductivity material having a high electrical resistivity in directions perpendicular to directions of the flow of the coolant through the flow path, an inlet at a first end of the channel that provides access to the flow path, and an outlet at a second end of the channel that provides access to the flow path.
