Abstract

The utility model relates to a heat sink of the central processor of a computer system, comprising heat conducting fins, a cover plate and a fan. The heat conducting fins are U-shaped and superposed on the top surface of a central processing unit. The cover plate is fixedly arranged on the top surface of the heat conducting fins; an air duct whose circumference is closed is formed between the cover plate and the heat conducting fins. An air inlet and an air outlet are respectively formed on both sides of the air duct. The fan is fixedly arranged on the lateral sideof the air inlet of the air duct. The heat which is produced by the central processing unit is absorbed by using the heat conducting fins. When the cold air which is sucked by the fan enters the air duct, the cold air is exhausted outside a host computer from the air outlet. The utility model can prevent heat flow from circulating in a machine body.

Description

The heat abstractor of the central processing unit of computer system

The utility model relates to a kind of heat abstractor, particularly a kind of heat abstractor of central processing unit of computer system.

As shown in Figure 1, be generally used in the CPU (centralpro-cessingunit in the computer system, central processing unit) used heat abstractor 10, CPU22 is provided in a side of in the CPU seat 21 of host computer, this CPU22 end face is stacked with one and is the heat conduction fin 11 of square type and establishes a fan 12 at these heat conduction fin 11 end faces, utilize this heat conduction fin 11 to draw the heat temperature that CPU22 produced, and the cold wind that is produced by this fan 12 brushes this heat conduction fin 11, make this CPU22 cooling and keep normal operation.Though above-mentioned heat abstractor 10 can make this CPU22 reach radiating effect, but, still there is following shortcoming in use: first, because this fan 12 be by cold wind with the heat of CPU22 to around shed, through the hot-air that this CPU22 sheds and, can heat to these CPU heat abstractor 10 internal system and other elements.The second, the position of the setting of this fan 12 is to be close to this CPU22 surface, makes the high heat on this CPU22 surface be directly conducted to this fan 12 bodies, causes the influence of this fan 12 because of CPU22 high temperature, and reduces effective serviceable life.

The purpose of this utility model is to provide a kind of and can dispels the heat to CPU and system element, and the heat abstractor of central processing unit of the computer system of fan life can be provided again.

The purpose of this utility model is achieved in that a kind of heat abstractor of central processing unit of computer system, comprises the heat conduction fin and a fan that can be stacked in the U type of central processing unit end face, and it is characterized in that: this heat abstractor comprises a cover plate in addition; This cover plate is installed in this heat conduction fin end face, and forms the ventiduct that all side seals close between this cover plate and heat conduction fin, forms an air inlet and an air outlet respectively in this ventiduct both end sides; This fan position is at the air inlet side of this ventiduct.

Owing to adopt above-mentioned technical solution, make the heat abstractor of the central processing unit of computer system of the present utility model have the advantage of the following stated: first, because fan 50 of the present utility model is position air inlets 331 in these ventiduct 33 1 sides, therefore, this fan 50 is the state that is isolation with CPU63, so, directly draw the heat of CPU63 except utilizing this heat conduction fin 30, also can pump cold wind and brush this heat conduction fin 30 by this fan 50, can help this CPU63 and 30 heat radiations of heat conduction fin, make this CPU63 can obtain best radiating effect.Second, because the air outlet 332 of this ventiduct 33 is to be connected with the exhaust outlet 62 of this main frame 60, when cold wind with after hot blast in this ventiduct 33 mixes, can apace hot blast be discharged outside the main frame 60 by this exhaust outlet 62 because of the crowded effect of sending of this ventiduct 33, can avoid hot-air to return the internal system of this main frame 60, so, this fan 50 has also had the effect that the computer system internal heat is discharged concurrently except bearing the heat sinking function of CPU63, makes the running of computer system more stable.The 3rd because at this fan 50 under the situation of isolating with CPU63, can keep the comparatively state of low temperature by the air-flow of this fan 50, make this fan 50 low temperature running, and can increase the service life.

Be elaborated below by most preferred embodiment and accompanying drawing heat abstractor to the central processing unit of the utility model computer system, in the accompanying drawing:

Fig. 1 is the stereographic map of CPU heat abstractor in the past.

Fig. 2 is the three-dimensional exploded view for the utility model preferred embodiment.

Fig. 3 is the constitutional diagram for the above-mentioned preferred embodiment of the utility model.

Fig. 4 is the use synoptic diagram for above-mentioned preferred embodiment of the utility model and main frame.

Fig. 5 is the stereographic map for another preferred embodiment of the utility model.

Shown in Fig. 2,3, the heat abstractor of the central processing unit of computer system of the present utility model comprises a heat conduction fin 30, a cover plate 40 and a fan 50.

This heat conduction fin 30 is the U type, and it is provided with a chute 31 respectively near two inboard places, top, and both sides are respectively equipped with two perforation 32 endways.

This cover plate 40 is inverted L shape, this cover plate 40 is made with aluminium alloy in the present embodiment, it comprises a surface level 41 and a vertical plane 42, this surface level 41 is embedded in the chute 31 of this heat conduction fin 30, and and ventiduct 33 that all side seals close of 30 formation of this heat conduction fin, and make these ventiduct 33 both end sides form an air inlet 331 and an air outlet 332 respectively, and this vertical plane 42 is to be posted by on this air inlet 331, and these vertical plane 42 central authorities are provided with an air guide hole 421, and respectively are provided with a screw 422 at four limit ends.

This fan 50 abuts on the vertical plane 42 of this cover plate 40, it respectively is provided with a perforation 51 corresponding to these screw 422 places, can tie with screw 422 locks for four screws 52 pass this perforation 51 in regular turn, make this fan 50 be fixed on air inlet 331 sides of this ventiduct 33, form an air intake surface in the side.

Cooperate shown in Figure 4, during assembly, need only cooperate the perforation 32 of this heat conduction fin 30, CPU seat 61 end faces at a main frame 60, correspondence is provided with four screws (figure does not show), air outlet 332 places that should ventiduct 33 in 60 pairs in this main frame are provided with an exhaust outlet 62, then, just this heat conduction fin 30 can be stacked and placed on a CPU63 end face, with a screw 64 pass in regular turn this heat conduction fin 30 perforation 32 and with this screwhole spiro bonding of 61, just can make this heat conduction fin 30 be fixed on this CPU63 end face, with this
