Document Type and Number:
Japanese Patent JP2022073134
Kind Code:
A
Abstract:
To provide a manufacturing method of a cooler component or the like for manufacturing inexpensively.SOLUTION: A plurality of protrusion parts protruding from a first surface are formed by pressurizing a second surface opposite to the first surface by a second die from a direction orthogonal to the second surface while the first surface of a flat plate-shaped material is supported by a first die. Portions on a second surface side are flattened so as to eliminate traces pressurized by the second die.SELECTED DRAWING: Figure 7
