1. A thermal module, comprising:
a radiating fin unit including radiating fin assemblies disposed in a stack, the radiating fin assemblies including a bottom radiating fin assembly, a top radiating fin assembly, and a middle radiating fin assembly, the middle radiating fin assembly being disposed between the bottom radiating fin assembly and the top radiating fin assembly, and each of the radiating fin assemblies being formed of a plurality of radiating fins sequentially fastened to one another in a horizontal direction to provide at least one contact surface thereon; and
a plurality of groups of heat pipes including a first group of heat pipes and a second group of heat pipes, each of the heat pipes including a heat absorbing section and a heat dissipating section formed at two ends thereof, the heat dissipating section of the first group of heat pipes being disposed between the bottom radiating fin assembly and the middle radiating fin assembly, and the heat dissipating section of the second group of heat pipes being disposed between the middle radiating fin assembly and the top radiating fin assembly, the heat absorbing sections of the heat pipes in each of the heat pipe groups being in contact with a heat source; and
the thermal module being characterized in that the heat dissipating sections of the heat pipes in each group are respectively horizontally extended from an outer side of one of two opposite shorter sides of one radiating fin assembly in the same direction as two opposite longer sides of the radiating fin assembly to another shorter side thereof, such that the heat dissipating sections are in full contact with the contact surfaces of corresponding radiating fin assemblies.
