摘要: Disclosed is a corrugated-fin type radiator (1), which comprises corrugated fins (10), and a support substrate (20) having a plurality of fixing grooves (23) defined by side walls (24) and a bottom (25). The bottom (25) has a ridge (26) at least in its portion, and the side walls (24) are formed of a vertical wall (24a), a tapered wall (24b) and a corner (24c). A fin fixing portion (14) is fixed along the side walls (24) and the bottom (25) of the fixing grooves (23). Also disclosed is a method for manufacturing the corrugated-fin type radiator (1), which comprises a substrate manufacturing step, a fin shaping step and a fixing step. Thus, it is possible to provide the corrugated-fin type radiator capable of improving a radiation efficiency, and a method for manufacturing the radiator.
