Connection frame for fan

摘要

A connection frame for fastening a fan of a heat sink is provided. The connection frame has side walls for defining an upper area and for mounting the fan thereon and a lower area to be coupled with the heat sink. The connection frame has a plurality of support struts on the lower area to wedge into the gaps of the fins of the heat sink for mounting the connection frame onto the heat sink. The connection frame further includes guiding parts extending from the side walls to reduce the airflow outlet so as to enhance the heat-dissipating efficiency.
