Thermal module for light-emitting diode

A thermal module for LED, comprising:

• a base having one of two sides in direct contact with an LED module;
• a first radiating fin assembly consisting of a plurality of parallelly arranged and spaced radiating fins, and being connected at one side to the other side of the base opposite to the LED module;
• at least one second radiating fin assembly consisting of a plurality of parallelly arranged and spaced radiating fins, so that an air passage is provided between any two adjacent radiating fins of the second radiating fin assembly;
• at least one heat pipe having a conducting section and at least one radiating section;
• the conducting section being extended through an interface between the base and the first radiating fin assembly to closely bear against the base and the first radiating fin assembly;
• and the at least one radiating section being outward extended from an end of the conducting section in a direction away from the base to extend through the second radiating fin assemblies;
• wherein the first radiating fin assembly is provided on the side contacting with the base with at least one groove;
• and
• wherein the base is correspondingly provided on the side contacting with the first radiating assembly with at least one groove, so that the groove on the base and the groove on the first radiating fin assembly together define a long hole for receiving the conducting section of the heat pipe therein.
