Radiating fin structure and heat sink thereof

Abstract

A radiating fin structure and a heat sink thereof. The radiating fin structure includes a main body. At least one input section and at least one output section extend from two ends of the main body respectively. The input section and the main body contain a first angle. The output section and the main body contain a second angle. The heat sink is composed of multiple radiating fins, at least one heat pipe and at least one chassis. The heat pipe penetrates through and strings the radiating fins to form one or more radiating fin assemblies. The input sections of the radiating fins of one radiating fin assembly are adjacent to the output sections of the radiating fins of another radiating fin assembly to together define a central heat dissipation section and multiple spiral heat dissipation flow ways as multiple flow guide structures to achieve better heat dissipation effect.
