WIPO Patent Application WO/2022/244570

A1

This cooling structure is provided with a press forming member which comprises groove parts and bank parts provided around the groove parts, a flow path upper lid which is a flat plate placed in a position covering the groove parts of the press forming member and which configures a flat cooling surface, and a laser welded parts which bond mutually facing surfaces of the flow path upper lid and the bank parts and which form flows path for flow of the cooling liquid. The press forming member and the flow path upper lid are plated steel plates comprising a base steel plate and Al-base plating, the flow paths comprise a parallel flow path area where multiple sub flow paths extending in a first direction are arranged in a second direction perpendicular to the first direction, and in the parallel flow path area, the interval between the mutually adjacent sub flow paths is less than or equal to 20 mm.
