said heat pipes each have a mounting part tightly fitted into said bottom open grooves of said base block and a flat wall portion formed on said mounting part and kept in flush with the bottom wall of said base block; and said thermal pad is a thin sheet of metal fixedly fastened to the bottom wall of said base block to hold down said heat pipes in said bottom open grooves and kept in close contact with the bottom wall of said base block. ### Claim 2 (depends on 1) The cooler module as claimed in claim 1, wherein said radiation fins of said heat sink each have a bottom notch fitting over the top wall of said base block. ### Claim 3 (depends on 1) The cooler module as claimed in claim 1, wherein the mounting part of each of said heat pipes is an extension arm disposed at one end of the respective heat pipe. ### Claim 4 (depends on 1) The cooler module as claimed in claim 1, wherein the mounting part of each of said heat pipes is a U-turn. ### Claim 5 (depends on 1) The cooler module as claimed in claim 1, wherein said base block is made out of copper or aluminum. ### Claim 6 (depends on 1) The cooler module as claimed in claim 1, wherein said thermal pad is made out of copper. ### Claim 7 (depends on 1) The cooler module as claimed in claim 1, wherein said thermal pad is affixed to the bottom wall of said base block by means of riveting or compression-bonding. ### Claim 8 (depends on 1) The cooler module as claimed in claim 1, wherein said base block has a plurality of upright fins perpendicularly protruded from the top wall. ### Claim 9 (depends on 1) The cooler module as claimed in claim 1, wherein said base block has a longitudinal cut in each of two distal ends of each of said bottom open grooves. ### Claim 10 (depends on 1) The cooler module as claimed in claim 1, wherein said heat pipes each have a first extension arm disposed at one end thereof and tightly inserted through the radiation fins of said heat sink, and a second extension arm disposed at an opposite end thereof and respectively fitted into the bottom open grooves of said base block; and the flat wall portion of each of said heat pipes is formed on the second extension arm of the respective heat pipe. ### Claim 11 (depends on 1) The cooler module as claimed in claim 1, wherein said heat pipes each have two extension arms respectively and tightly inserted through the radiation fins of said heat sink, and a U-turn connected between said two extension arms; and the flat wall portion of each of said heat pipes is formed on the U-turn of the respective heat pipe. ### Claim 12 (depends on 9) The cooler module as claimed in claim 9, wherein said heat pipes each have two extension arms respectively and tightly inserted through the longitudinal cuts of the bottom open grooves and through the radiation fins of said heat sink, and a U-turn connected between said two extension arms; and the flat wall portion of each of said heat pipes is formed on the U-turn of the respective heat pipe. ### Claim 13 (depends on 12) The cooler module as claimed in claim 12, wherein said base block has a plurality of upright fins perpendicularly protruded from the top wall.
