Latest Patents

Hisashi Segawa holds 1 patent for a method of producing a heat exchanger. This patent describes a fin member for a heat exchanger that is produced by repeatedly folding a plate over itself into a corrugated shape to form corrugated fins. The folded sections are pressed and deformed into a recessed shape to create engagement recesses. A pipe member, through which fluid flows, is disposed at these engagement recesses. The pressing and deformation of the engagement recesses result in swollen sections that protrude on both sides of each folded section, forming flat butt surfaces at the tips. These adjacent butt surfaces are designed to be in surface contact with each other, ensuring efficient fluid flow through the pipe member.
