Abstract
Fixing units for connecting a heat dissipation device to a heat source are pre-mounted to four points on the former and respectively include a spring loaded screw having a spring fitted thereon and stopped by a retaining ring from moving down out of the spring loaded screw; a screw sleeve having the spring loaded screw received therein and being provided at an upper open end with two diametrically opposite notches; and a spring retainer fitted around the upper open end of the screw sleeve and having a pair of upward retaining plates, which are extended through the notches to abut on and compress the spring. To connect the heat dissipation device to the heat source, simply apply an external force or use a tool to release the retaining plates from the springs, and the released springs synchronously provide even forces to push the heat dissipation device against the heat source.
