Abstract: A heat dissipation module includes a heat dissipation device, a resilient bracket and a cylindrically shaped nut. The heat dissipation device is attached to a heat generating component. The cylindrically shaped nut has an arc surface and two circular surfaces. A screw hole is formed on one of the two circular surfaces and an engraved slot is formed on the arc surface. The resilient bracket is secured to the heat dissipation device at an end and has a U-shaped cutout at an opposite end, wherein the U-shaped cutout has a constricted opening for receiving the cylindrically shaped nut. The U-shaped cutout engages with the engraved slot.
