A heat radiating fin assembly is formed from alternately stacked first and second heat radiating fins. The first and the second heat radiating fins each are provided on at least one lateral side with a projected point and a receded point, respectively, to thereby define an airflow guiding section on at least one longitudinal side of the heat radiating fin assembly. The airflow guiding section includes a first and a second airflow inlet, and a middle airflow inlet located between the first and the second airflow inlet. The heat radiating fin assembly can be associated with at least one heat pipe and a base to form a thermal module. The airflow guiding section enables widened airflow inlets, shortened airflow paths, reduced airflow pressure drop and flowing resistance, and upgraded cooling air flowing efficiency, so that the heat radiating fin assembly and the thermal module can provide excellent heat dissipating effect.
