Heat sink module

Abstract

A heat sink module includes at least one heat conduction base, at least one heat conduction pipe and a fin heat sink. The heat conduction base has a recess and at least one engaging protrusion on the recess. The heat conduction pipe has a heat absorption end and a heat dissipation end. The heat absorption end is attached to the recess of the heat conduction base and engaged with the engaging protrusion. The heat dissipation end is coupled to the fin heat sink. The fin heat sink is composed of a plurality of fins which are disposed side by side and connected by the heat dissipation end of the heat conduction pipe. The fin heat sink has an engaging groove for engagement of a curved section of a fixing plate of a heat dissipation fan. The heat dissipation fan can be quickly coupled to the fin heat sink, simplifying the assembly of the heat sink module.
