Description
FIELD OF THE INVENTION

The present invention relates to a thermal dissipation device, especially to a thermal dissipation device used on the heating electrical components for thermal dissipation performance.

BACKGROUND OF THE INVENTION

Thermal dissipation devices are very popular in the electrical devices, such as a computer, which CPU has one thermal dissipation device (i.e. cooler) with a fan for increasing the heat conduction performance. If the performance of the thermal dissipation device is not good, CPU will be over heating and the processing speed of CPU will also be affected, or even forces this CPU burning out. Therefore, a good thermal dissipation device is a very important component for high efficiency electronic devices (such as a computer). FIG. 1 is the block diagram of the traditional thermal dissipation device. The upper side 11 of the thermal dissipation device usually connects with one fan, and the down side 12 usually connects with the heating electronic components (such as a CPU). The heat of the thermal dissipation device will be conducted outside when the fan runs. The kernel part of this thermal dissipation device is solid, the surface of this thermal dissipation device is implemented by several heat sink fins; when the fan runs, the thermal dissipation performance of these heat sink fins will be better, but the thermal of this thermal dissipation device is distributed from the solid kernel to the surface. At this situation, this solid kernel connects with the electronic components with most heat, but the thermal dissipated by the fan is the least. That is, the fan cannot conduct the thermal effectively for this design of heat sink fins.

FIG. 2 is a block diagram of another conventional thermal dissipation device. This thermal dissipation device is assembled with several heat sink fins 22, several heat pipe 21 and base site 23. It is not easy to implement this thermal dissipation device because heat pipe 21 has to be passed through every heat sink fin 22 with high cost; and takes larger space and inefficient thermal conduction.

SUMMARY OF THE INVENTION

An objective of the present invention is to provide a new thermal dissipation device able to conduct thermal efficiently, increase thermal dissipation area, enhance the thermal dissipation performance, decrease space and optimize the heat sink performance of the fan.
