Abstract: A method of mounting a heat dissipation device to a bare die heat source using fixing elements is disclosed. The fixing elements respectively include a screw, which has a spring fitted thereon and is disposed in a sleeve. Limiting units are provided on the sleeve for holding the spring in the sleeve in a compressed state. To mount the heat dissipation device to the bare die heat source, first use the fixing elements to preliminarily screw the heat dissipation device to a top of the heat source. Then, the springs compressed in the sleeves of all the fixing elements are elastically released synchronously to apply evenly distributed downward forces that push the heat dissipation device toward the bare die heat source stably.

Abstract: A reworkable fixing element includes a screw having a spring fitted thereon, a screw head with two opposite cuts, and a retaining ring for stopping the screw from axially moving down any further; a sleeve disposed outside the screw and the spring, and including two opposite windows near an upper end thereof and a coupling zone located below the windows; a spring retaining ring fitted around the coupling zone and including two upward hooked arms extended through the windows to press the spring to a compressed state. The used fixing element has an elastically released spring but is reworkable using a reworking tool, which pushes the spring into the sleeve via the two cuts. Then, the hooked arms are allowed to extend through the windows to press on and hold the spring in the compressed state again, and the fixing element is ready for use a second time.

Abstract: A heat dissipation unit includes a heat sink having a heat receiving zone and a screw fixing structure extended through each of four holes on the heat sink outside the heat receiving zone. The screw fixing structure includes a locating screw having a shank and a spring fitted around the shank; a hollow sleeve located outside the shank and the spring; and a spring stopper including two parallel elastic arms connected at one end and elastically disposed in the hollow sleeve to hold the spring in a compressed state. The spring stopper may be pushed downward to laterally push the two elastic arms open to move away from the spring, allowing the spring to release its elastic force upwardly. The four locating screws can synchronously and evenly apply their elastic force to the through holes outside the heat receiving zone, preventing the heat sink from damaging a contacted heat source.

Abstract: A heat dissipation unit is connected to a bare die heat source by extending connecting elements through four predetermined corners on the heat dissipation unit. The connecting elements respectively include a screw having a spring fitted therearound; a sleeve defining a receiving space for receiving the screw and the spring therein, and having a window formed near an upper end thereof to radially communicate with the receiving space; and a turnable retaining ring fitted around the upper end of the sleeve and including a tongue curled toward a center of the turnable retaining ring and being extendable through the window into the receiving space to compress the spring. When all the turnable retaining rings are turned, the tongues can be moved away from the springs, allowing the springs to release their elastic force synchronously and push the heat dissipation unit toward the bare die heat source evenly for heat exchange.

Abstract: A heat dissipation unit includes a main body and a plurality of fixing elements. The main body has a heat receiving zone and a plurality of through holes formed at four corners outside the heat receiving zone. The fixing elements are mounted in the through holes and respectively include a screw having a spring fitted thereon; a sleeve disposed outside the screw and the spring and having a pair of windows formed near an upper end; and a spring retaining ring fitted around the sleeve and having a pair of upward extended hooked arms extended through the windows to compress the spring in the sleeve. When the fixing elements have been assembled to the main body, the springs can be released at the same time and can therefore apply even downward forces synchronously for the main body to closely and evenly contact with a bare die heat source.

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.

Abstract: A thermal module includes a base seat and multiple heat pipes. The base seat has a heat absorption side and a heat conduction side. Each heat pipe has a heat absorption end and a heat dissipation end. The heat absorption end has a pair of long sides and a pair of short sides. The long sides and the short sides are connected with each other in the form of a loop to form the heat absorption end. The heat pipes are assembled with each other with the long sides attached to each other. The heat pipes are assembled with the base seat with the short sides attached to the heat conduction side of the base seat. By means of the above arrangement, the number of the heat pipes disposed in a limited area or space can be greatly increased to enhance the heat conduction efficiency.
