    Patent number: 5542176
    Abstract: This invention is to provide a radiation plate which prevents a generation of resonance phenomenon and being suitable for automation. A plurality of groove are formed in parallel in a base, and a part of a fin consisting of a material having relatively low hardness such as a pure aluminum formed with an engaging portion with concave or convex portion is fitted to each of the grooves. The pressure is applied in perpendicular direction to the vicinity of the grooves of the base to form a pressure deformed portion, and the part of the fin is fixed to the wall surface of the groove of the base by the bonding force of the pressure deformed portion against the fin.
