Heat dissipating module

摘要

A heat dissipating module is adapted for dissipating thermal energy from an electronic element mounted on a circuit board, and includes a heat sink, a heat conductive board including a plurality of tube portions that extend through the circuit board, a heat conductive tube that interconnects the heat sink and the circuit board, and a plurality of fixing elements. Each fixing elements includes a first end part be secured to the heat conductive board, a second end part exposed from an end opening of a respective tube portion, and a pair of interference parts that extend resiliently, respectively and outwardly through lateral openings of the respective the tube portion for abutting against the circuit board. The heat dissipating module further includes a resilient unit disposed between and connected resiliently to the circuit board and the heat conductive board.

1. A heat dissipating module adapted for dissipating thermal energy from an electronic element mounted on a circuit board, the circuit board having a first board surface and a second board surface, the electronic element being mounted on the first board surface, said heat dissipating module comprising:
a heat sink; a heat conductive board including
a board body that has a third board surface adapted to confront the electronic element, anda plurality of tube portions that protrude from said third board surface of said board body and that are adapted to extend through the circuit board, each of said tube portions defining an end opening that is distal from said third board surface and having a pair of lateral openings; a heat conductive tube interconnecting said heat sink and said board body of said heat conductive board; a plurality of fixing elements extended respectively through said tube portions of said heat conductive board, each of said fixing elements including
a longitudinally extending part that is disposed in a respective one of said tube portions,a first end part that is connected to an end of said longitudinally extending part and that is adapted to be secured to said board body,a second end part that is connected to an opposite end of said longitudinally extending part and that is exposed from said end opening of the respective one of said tube portions, anda pair of interference parts that are connected to said longitudinally extending part between said first and second end parts, that extend resiliently, respectively and outwardly through said lateral openings of the respective one of said tube portions, and that are adapted for abutting against the second board surface of the circuit board; and a resilient unit adapted to be disposed between and connected resiliently to the first board surface of the circuit board and said third board surface of said heat conductive board.
