ートシンク。[Claims for Utility Model Registration] (1) A flat serpentine tube formed by bending a flat rolled metal tube in the direction of the long axis of the flattened tube at multiple locations in the longitudinal direction, through the flat long side of the flattened serpentine tube. A heat sink characterized by being joined to a cooling plate. (2) The ratio of the length of the short side to the long side in the cross section of the flat serpentine tube is 0.5 to 0.25, and the minimum bending radius in the direction of the flat long axis is 1.5 to 1.5 of the length of the long side. 2
The heat sink according to claim 1, characterized in that the heat sink is twice or more.
