• a front base board is a base body of a long board with its top plane disposed with a front base insert groove at an inclined angle for inserting and assembling the front insert piece;
• the rear side thereof is disposed with a cut groove provided for inserting and hooking a retaining tab so as to fasten the hot tube;
• a rear base board is a base body of a long board with the top plane thereof disposed with a rear base insert groove at an inclined angle for the inserting and assembling the rear insert piece;
• two hot tubes are pressed flatly and affixed to the bottom plane of the heat sink base by means of heat conducting sticker;
• two positioning clamps with a press-against portion disposed on the inner plane thereof for pressing against the hot tube;
• two lateral sides thereof corresponding to the retaining holes are disposed with retaining hooks for retaining and fastening with the retaining holes;
