Description

The heat abstractor combination

[technical field]

The utility model is about a kind of heat abstractor combination, particularly about a kind of heat abstractor combination that can evenly dispel the heat rapidly.

[background technology]

Along with electronic industry constantly develops, the microprocessor speed of service constantly promotes.But the heat that high-frequency high-speed produces microprocessor is more and more, and the performance and the stability of microprocessor operation in serious threat, is a large amount of heats of guaranteeing the normal operation of microprocessor energy, must use heat abstractor in time to get rid of microprocessor to be produced.

Common heat abstractor combination, as No. the 89214786th, 89213022, Taiwan patent application etc., these patents include a radiator, and this radiator comprises a heat dissipation base and is welded in radiating fin on this base, this heat dissipation base is the entity metal and does not have the heat pipe cooperation that radiating rate is slow.Industry is for promoting radiating effect, heat pipe is added in the radiator, these heat abstractors comprise a heat dissipation metal base, radiating fin, heat pipe and fan, as No. the 089205047th, Taiwan patent application, by the effect of heat pipe quickened heat dissipation base and radiating fin between heat transferred, but, lean on the conduction heat conduction of metal between this heat dissipation base and CPU, and directly do not contact between radiating fin and heat dissipation base, its heat concentrates on the heating tape place of CPU, it is inhomogeneous easily to cause dispelling the heat, thereby influences the integral heat sink effect, and then influences the normal operation of central processing unit.

[summary of the invention]

The purpose of this utility model is to provide a kind of heat abstractor combination that can evenly dispel the heat rapidly.

The purpose of this utility model realizes by following technical proposal: the utility model heat abstractor combination comprises a heat dissipation base, a radiating bottom plate and is located at radiating fin, plurality of U-shaped heat pipe, a fan holder and a fan on the radiating bottom plate.Be provided with in this heat dissipation base a chamber and in be filled with hydraulic fluid, the affixed plurality of U-shaped heat pipe of this heat dissipation base one side, this heat dissipation base ccontaining radiating bottom plate in top and be located at radiating fin on this radiating bottom plate, these radiating fins are provided with through hole and plug for the opposite side of U-shaped heat pipe; This fan can by the fan holder be fixed in this radiating seat, radiating bottom plate and be located at radiating fin on this base plate and the combination of these heat pipes on.The heat that this heat abstractor combination can make CPU shed evenly distributes, and has improved radiating rate, thereby reaches the effect of evenly dispelling the heat rapidly.

Compared with prior art, the utility model heat abstractor combination has adopted heat pipe to combine with heat dissipation base and radiating fin, and the mode that also is connected with heat dissipation base of radiating fin, reaches the effect of evenly dispelling the heat rapidly.

[embodiment]

See also Fig. 1 and Fig. 2, the combination of this creation heat abstractor comprises a heat dissipation base 12, a radiating bottom plate 16 and is located at the radiating fin 18 on this radiating bottom plate, some heat pipes 14, a fan holder 30 and a fan 50.This heat dissipation base 12, radiating bottom plate 16 and radiating fin 18 one-tenth cooling bases 17 capable of being combined, this cooling base 17 can be combined into radiator 10 with heat pipe 14.

This heat dissipation base 12 is provided with a chamber 122, is filled with first hydraulic fluid (figure does not show) of tool good heat exchange performance in this chamber 122, and is provided with first capillary structure (figure does not show) in these chamber 122 internal faces.One sidewall of this heat dissipation base 12 is provided with some coupling holes 121, this heat dissipation base 12 both sides identical with these coupling hole 121 bearing of trends have buckle slot (not label), this heat abstractor are made up (figure does not show) on the microprocessor surface that is fastened on the circuit board for fastener (figure does not show).This heat pipe 14 is the short U-shaped of a side, its short side is fixed in the coupling hole 121 of heat dissipation base 12, be filled with second hydraulic fluid (figure does not show) of tool good heat exchange performance in this heat pipe 14, and be provided with second capillary structure (figure does not show) in inner wall surface thereof.When the shorter lateral sides of such of this heat pipe 14 stretches into certain-length and is fixed in the coupling hole 121, radiating bottom plate 16 lids place heat dissipation base 12 radiating bottom plates 16 lids to place chamber 122 tops of heat dissipation base 12, and make these radiating bottom plate 16 airtight first hydraulic fluids and heat pipe 14 1 ends in the chamber 122 of heat dissipation base 12, and the L shaped radiating fin 18 that is arranged in parallel on this radiating bottom plate 16, this heat dissipation base 12, radiating bottom plate 16 and radiating fin 18 form cooling base 17.In addition, all be provided with a circular hole on each radiating fin 18,, plug than long side with another of heating tube 14 with corresponding formation one lengthwise through hole 20.Stretching in the fixed via 20 of heat pipe 14 than long side; Thereby heat pipe 14 is formed this radiator 10 with this cooling base 17.

The appropriate location that the framework of this fan 50 is four jiaos is provided with perforation 52, wears for screw (figure does not show).

This fan holder 30 comprises a matrix 32, these matrix 32 central authorities set out a circular hole 34, this matrix 32 offers locking hole 36 in end appropriate position, the angle of circular hole 34, the both sides of this matrix 32 are extended side plate 38 respectively downward vertically, this side plate 38 bottoms setpoint distance at interval are provided with some straight joints 42, and these side plate 38 bottoms are located respectively level near two ends and extended inwardly and fix sheet 40.
