Abstract
A heat sink module includes a heat dissipation pad. The heat dissipation pad is flexible and has a cambered shape, and is pressed to become a flat plate when disposed between the heat sink module and a CPU. The heat dissipation pad restores to its original cumbered shape and lifts the heat sink module away from a CPU when a fixing device that fixes the heat sink module to the CPU is disabled. Therefore, one can easily removes the heat sink module without any additional tools or processes.
Claims13
A heat sink module, comprising:
- a base;
- a heat dissipation pad being flexible and biased to a cambered shape, the heat dissipation pad having a fixing portion coupled to the base and a flexible portion extending deflectively therefrom to terminate at a free end, wherein the flexible portion of the heat dissipation pad deflectable to a substantially flat configuration when captured between a heat conducting plate and a CPU;
- and
- a heat pipe, which one end connects the heat conducting plate to bring away heat accumulated at the heat conducting plate.
1 more element
A heat sink module for a heat generating device comprising:
- a frame for supporting the heat generating device;
- a base detachably coupled to the frame;
- a heat dissipation pad releasably captured against the heat generating device by the base when the base is coupled to the frame, the heat dissipation pad having a fixing portion coupled to the base and a flexible portion extending deflectively therefrom to terminate at a free end, the flexible portion being biased to a cambered shape, the flexible portion being deflectable to a substantially flat configuration when captured by the base against the heat generating device, wherein the base includes a heat conducting plate, the flexible portion extending substantially over the heat conducting plate.
