Abstract
Abstract A stack-fin radiator comprises a base and a fin set. One surface of the base is separated into a central first portion and two second portions on the two sides of the first portion. The fin set formed by a first fin unit and a second fin unit, the first and second fin units are formed by stacking a plurality of first fins and second fins. Connecting pieces being used to penetrate the first fins and the second fins so that the first fins and the second fins are connected in series, the first fins and second fins are also fixed on the respective first and second portions of the base. By the aforementioned structure, the stack-fin radiator with high heat dissipation efficiency, higher mold cost and of easily manufacturing are achieved.
