In order to achieve the above creative purpose, the technical means used in this creation is to design a cooling device for transformers and capacitors on the motherboard, which has a main cooling fin, a primary cooling fin, a heat pipe, at least one fixing piece, and two positioning fins. fin and a fan, one end of the main heat dissipation fin is formed with accommodating grooves, concave card edges are respectively formed on both sides of the main heat dissipation fins and at positions away from the accommodating grooves, and one end of the secondary heat dissipation fins is formed There are accommodating grooves, and concave card edges are respectively formed on both sides of the secondary heat dissipation fins and at positions away from the accommodating grooves. One end of the heat pipe is passed through and fixed on the main heat dissipation fins, and the other end is passed through and fixed on the main heat dissipation fins. At the secondary heat dissipation fins, clips are respectively fixed at both ends of the fixing piece, inner flanges are formed on both sides of each positioning piece, and a connecting piece is provided at one end of each positioning piece.

As in the above-mentioned structure, when the distribution area of the transformer and capacitor on the motherboard is small, one end of the fan is arranged at the position of the accommodating groove of the secondary heat dissipation fin, and several screws penetrate the fan, and are screwed with the main heat dissipation fin. and the other end of the secondary heat dissipation fin is placed above the fixed piece, and the inner flange of the positioning piece and the concave card edge of the secondary heat dissipation fin are fastened to each other, and then the connecting piece of the positioning piece is clamped to the fixed piece. the clip of the film;

If, when the distribution area of transformers and capacitors on the motherboard is large, one end of the fan is set at the position of the accommodating groove of the main heat dissipation fin, and several screws pass through the fan and are screwed together with the secondary heat dissipation fin. And the other end of the main cooling fin is placed on the top of the fixing piece, and the inner flange of the positioning piece and the concave card edge of the main cooling fin are mutually clamped, and then the connecting piece of the positioning piece is clamped and fixed on the fixing piece. At the clip.

The user can choose the one he needs to use according to the above two combinations, and fix the cooling device on the motherboard, so that the high temperature generated by the transformer and the capacitor can be dissipated into the air.

Since the user can choose to use the main heat dissipation fins or the secondary heat dissipation fins, this creation can be used on motherboards of various specifications. In addition, the manufacturer only needs to produce a heat dissipation device of a single specification, and it can provide various specifications. The mainboard of this invention is used, and the cooling device of this creation has the convenience of its use and manufacture.
