Clip and heat dissipation assembly using the same

A heat dissipation assembly comprising:

• a heat sink;
• a mounting seat comprising a frame and two engaging units formed at two opposite sides of the frame;
• and
• a clip comprising a spring arm and an ear, the spring arm comprising two wires, a hook formed at one end of the spring arm to connect ends of the wires and two barbs each formed at another end of each of the wires, a central portion of each of the wires projecting downwardly, the ear comprising a main body, two notches in an upside of the main body and a clamping unit at a downside of the main body, each of the notches comprising from above to below an insertion slot, an elongated sliding slot and a retaining slot;
• wherein the heat sink is received in the frame, the spring arm of the clip abuts against the heat sink, the hook of the spring arm engages with one of the engaging units of the frame, the clamping unit of the ear engages with the other one of the two engaging units, the spring arm engages with the ear with the barbs extending into the insertion slots, and the wires are slideable downwardly along the sliding slots to be fixed in the retaining slots to cause the wires to exert a downward force on the heat sink towards the mounting seat.

A heat dissipation assembly for dissipating heat from a heat-generating component comprising:

• a heat sink;
• and
• a clip attached to the heat sink adapted for mounting the heat sink to the heat-generating component, the clip including:
• a spring arm comprising at least one linear wire attached to the heat sink and a locking unit formed at a first end of the at least one linear wire;
• and
• an ear attached to a second end of the least one linear wire and defined with at least one notch therein, the at least one notch including an insertion slot and a retaining slot respectively at top and bottom ends of the at least one notch, and a sliding slot between the insertion slot and the retaining slot, said second end of the least one linear wire inserted into the insertion slot and moveable downwardly from the insertion slot along the sliding slot to be fixed in the retaining slot.
