Abstract:
1. A cooler module, comprising: a plurality of radiation fins; and a plurality of heat pipes fastened to said radiation fins to hold said radiation fins in parallel, each said heat pipe having a first end pipe section and a second end pipe section, the second end pipe section having a flat bottom surface portion exposed to the outside of said radiation fins for bonding to a semiconductor device for enabling said heat pipes to transport heat from said semiconductor device to said radiation fins for dissipation, wherein said radiation fins are arranged in a stack to form a horizontal block-like radiation fin module, each said radiation fin having a plurality of full through holes cut through two opposite sides thereof for the mounting of said heat pipes; said heat pipes are sealed hollow U-pipes with the first end pipe sections respectively and tightly fitted into the full through holes of said radiation fins, wherein each said radiation fin has a bottom side and a plurality of bottom notches formed on the bottom side; the second end pipe sections of said heat pipes are respectively tightly fastened to the bottom notches of said radiation fins and peripherally contacted with the bottom notches of said radiation fins with the flat bottom surface portions in flush with the bottom sides of said radiation fins, such that the bottom sides of said radiation fins and the flat bottom surface portions of the second end pipe sections together form a single flat surface as a bottom-most portion of the cooler module, wherein the bottom notches have a bottom opening narrower than immediately inside the bottom opening for keeping the second end pipe sections of said heat pipes tightly fastened to the bottom notches of said radiation fins.
