Abstract

Cold plates for liquid cooling systems, methods for the cold plates, and vehicles including the cold plates are provided. The methods include welding together a first substrate and a second substrate with weld lines, inflating portions of at least the second substrate between the weld lines to form a network of channels between the first substrate and the second substrate and thereby produce a cold plate, installing the cold plate to be in thermal contact with an apparatus that produces heat during operation thereof, wherein the apparatus includes a housing and the cold plate is welded to a portion of the housing or defines a portion of the housing, and coupling the cold plate to a liquid cooling system configured to supply a coolant to the network of channels to remove the heat from the apparatus.
