Thermal module

Abstract

A thermal module includes a radiating fin assembly having first heat conducting sections located at a lower middle portion thereof, second heat conducting sections located adjacent to outer sides of the first heat conducting sections, first heat dissipating sections located closer to upper outer portions of the radiating fin assembly, and second heat dissipating sections located adjacent to inner sides of the first heat dissipating sections; first heat pipes each having two ends separately inserted into the first heat conducting and dissipating sections; and second heat pipes each having two ends separately inserted into the second heat conducting and dissipating sections. Therefore, heat source can be transmitted by the first heat pipes from the high-temperature lower middle portion of the radiating fin assembly to the low-temperature upper outer portions of the radiating fin assembly and quickly dissipated into ambient air without stagnating in the middle of the radiating fin assembly.
