Specific embodiment

With reference to the accompanying drawings to describe the present invention, wherein indicating similar or phase using being identically numbered in all the drawings Same element.Attached drawing is not necessarily drawn to scale and is only to illustrate the present invention.It is retouched referring to the exemplary application for explanation State several aspects of the invention.It should be understood that listing many details, relationship and mode to provide for of the invention Comprehensive understanding.It, can be in none or multiple details however, the ordinary skill of related fields will recognize immediately Or get off to realize the present invention using the case where other methods.In other cases, be not shown specifically well known structure or operation with Avoid confusion the present invention.The sequence of behavior or event the present invention is not limited to shown in, some behaviors may in a different order and/ Or occur simultaneously with other behaviors or event.In addition, and the not all behavior shown or event require side according to the present invention Method is implemented.

As shown in Fig. 1 (prior art), pipeline flowing may include conventional tube 10, receives and enters air (incoming Air) 12 and guide air to flow through server 18 the preceding memory 14 of front side 19 and the rear side of server 18 or downside 22 after Memory 16.Especially, pipeline 10 leads into air 12 first and flows through memory 14.Pipeline 10 collection flow through memory 14 with The air of the other parts of pipeline 10, to provide cooling air (cooling air) 20 to background storage 16.Pipeline 10 also makes Into the steering of air 12 far from any central processing unit (CPUs) in server 18, to avoid these central processing unit (CPUs) it is heated into air 12.The air that enters that adjacent pipeline (not shown) can be used to carry out leader flows through neighbouring deposit The central processing unit (CPUs) of reservoir 14 and memory 16.

When being used together when the memory element with lower-wattage, pipeline 10 allows access into air 12 and keeps enough cold to mention For effective cooling of memory 14 and memory 16.However, since new high-speed memory technology has higher power demand, The each of memory 14 and memory 16 consumes more high heat in which can dramatically.Memory power is up to 18 watts (Watt, W). This causes memory temperature to reach more than 85 degree Celsius (memory specifications).So into pipeline 10 enter air 12 can be Before flowing through memory 14 and reaching memory 16, it is preheated significantly.The preheating into air 12 in pipeline 10 causes Any cooling air 20 for reaching memory 16, which has, enters the higher temperature of air 12 compared with the cooling for entering pipeline 10.This Therefore preheating reduces the cooling efficiency for reaching the cooling air 20 of memory 16 into air 12.Then, this is reduced Therefore cooling efficiency may cause the temperature of memory 16 to be more than operations specifications, and may further result in the mistake of memory 16 Effect even goes back early failure than expected.

In view of the limitation for traditional cooling line configuration of new memory technology, the present invention considers new pipeline and sets Meter is illustrated in Fig. 2 and Fig. 3.Fig. 2 is painted the lateral sectional view of the server according to the present invention comprising pipeline flowing. Fig. 3 is painted perspective view, the partial sectional view of the server according to the present invention comprising pipeline flowing.

Although specification is directed to the realization of certain types of arithmetic unit (i.e. server), this is merely for convenience of solving It releases.So the present invention is suitable for inclusion in any operation device of heat emitting electronics, wherein heat emitting electronics are relative to air-flow And it is set in masking configuration.Therefore, the present invention considers the element that such arithmetic unit may include any kenel, such as center Processing unit (CPU), graphics processor (graphics processing unit, GPU), memory and similar electronics fill It sets.

As shown in Figure 2 and Figure 3, the pipeline flowing 25 of server 18 includes pipeline 32, pipeline 31 and pipeline 30.Respectively such as arrow Person indicated by first 26,27 and 28, pipeline 32, pipeline 31 and pipeline 30 divide will enter air 12 for three parts.Configure these Pipeline is to provide the cooling of the different piece of server 18.

With reference first to pipeline 30, this pipeline is mainly to provide the cooling of the rear CPU in server 18.Especially, such as Fig. 3 In arrow 28 ' shown in, the part as shown in arrow 28 is directed to flow across pipeline 30 and is then drawn first into air 12 It is directed at rear CPU 42.The inner surface of pipeline 30 not only provides the necessary guidance of air-flow, but also promotes to flow through the part of pipeline 30 Into 12 smooth flow of air.That is, the entrance air of this part follows not first, by preceding CPU 40, (its position is in figure Indicated in 3 with dotted line) path.So, because not by preceding CPU 40, suffering from into air 12 for this part is less Preheating or be not preheated.Correspondingly, it as shown in arrow 28 ', then guides to the part of rear CPU 42 and enters air 12 Colder air is provided for CPU 42 after cooling.

Referring next to pipeline 32, the mainly cooling to memory 14 before providing of this pipeline.In addition, this pipeline is also to mention It is cooling for the part of rear CPU 42.As shown in Figure 2 and Figure 3, as shown in arrow 26, the air 12 that enters of part is guided to flow first By the road 32.For cooling preceding memory 14, pipeline 32 is to guide the air 12 that enters of this part to flow through preceding memory 14.It Afterwards, as shown in the arrow 26 ' in Fig. 3, the air 12 that enters of this part is directed to rear CPU 42 also by exhaust outlet 33.Pipe The inner surface on road 32 can be configured to that the part for flowing through pipeline 32 is promoted to enter 12 smooth flow of air.

Although the air being discharged through exhaust outlet 33 can be heated by memory 14, heated by memory 14 The amount for the air that CPU 40 is heated before the amount of air is usually less than.So the air being discharged through exhaust outlet 33 can still have foot Enough abilities cool down hotter element, for example, after CPU 42.Then, as shown in arrow 26 ', part that exhaust outlet 33 is discharged Into air 12 for CPU 42 after cooling.

As shown in figure 3, opening portion 38 of its at least part for showing pipeline 30 with CPU 40 forward, and pipeline 32 It not comprising such opening portion (in addition to exhaust outlet 33), that is, include wall 37.In pipeline 32, wall 37 is designed to holding part Memory 14 is directed to flow across without being heated by CPU 40 into air 12.However, the present invention considers in some structures, pipe Road 32 can also have opening portion or even seem that pipeline 30 in Fig. 3 fully opens like that.Similarly, pipeline 30 can be optionally It is designed to similar to pipeline 32.That is, it is colder in order to maintain to flow through the entrance air of the part of pipeline 30, it also can provide wall 36 (being indicated with dotted line) separate the inside of pipeline 30 and CPU 40.

Other than pipeline 30 and pipeline 32, as shown in Figure 2 and Figure 3, pipeline flowing 25 also may include be located at pipeline 30 with Pipeline 31 between pipeline 32.This pipeline is to provide the cooling of background storage 16.As depicted in Fig. 2 and Fig. 3, such as arrow Shown in 27, configuration pipeline 31 makes the air 12 that enters of part be directed to background storage 16, without being stored by 14 or appointing One CPU 40 or CPU 42 are preheated.Therefore, the air 12 that enters for reaching the part of memory 16 keeps cooling, deposits to provide Effective cooling of reservoir 16.Such as pipeline 30 and pipeline 32, the inner surface of pipeline 31 can be configured to smoothly guide air.

Although Fig. 2 and Fig. 3 show the specific configuration and size of pipeline 30, pipeline 31 and pipeline 32, the present invention considers The other configurations of these pipelines can also use without restriction.Therefore, the configuration of pipeline can be each based on what is be cooled with size The size of kind of element, the configuration in server 18, the available space in server 18 and various elements cooling requirement and Change.For example, although pipeline 30, pipeline 31 and pipeline 32 are shown to include common wall in Fig. 2 and Fig. 3, In other embodiments, these pipelines may include different walls.In other examples, although pipeline 30, pipeline 31 and pipeline 32 It is illustrated as providing substantial parallel and adjacent to each other air path in Fig. 2 and Fig. 3, but in other embodiments, this A little pipelines do not need adjacent to each other or parallel to each other.

In some embodiments, pipeline 30, pipeline 31 and pipeline 32 can be by the motherboards 24 that configured in server 18 On single shell 35 and define, support memory 14, memory 16 and CPU 42.However, the present invention considers pipeline 30, pipe Road 31 any number of element can be used to define with pipeline 32.

The material of the construction of pipeline described in this specification can be low thermal conductivity material, to minimize between shared Wall (such as separate the wall 34 of pipeline 30 and pipeline 31 and separate the shared wall 37 of pipeline 31 and pipeline 32) between appoint What heat transfer.Suitable material for pipeline includes polymer and ceramics.However, in other implementations, can be used With the 0.55 watt/any materials of (meter Du) (W/ (mK)) or lower pyroconductivity under 25 degree Celsius.
