Abstract: PURPOSE: A structure for assembling the radiating fins of an electronic chip cooling device is provided to minimize the bad on a manufacturing process due to a solid fixing state after assembling the radiating fins and largely reduce a working time for an assembling process by making the radiating fins in one body. CONSTITUTION: A terminal base(110) conducts the heat by directly contacting to a heating element such as a CPU. The first and the second heat pipes(120,130) are soldered to an upper part of the terminal base. The first and the second radiating blocks(140,150) are formed in a vertical/horizontal direction by soldering the radiating fins(141,151) to an end of the first and the second heat pipe. A fan motor(160) forcibly circulates cooling fluid to the radiating block. A base frame fixes the fan motor and the terminal base. A fan cover efficiently flows in/out the cooling fluid by isolating a large portion except an upper center of a fan motor installing part. The radiating block is formed as one body by an insert method injecting plastic after arranging the radiating fins on a metal mold.

The waste paper is inserted into the groove.
