Present weight reducing PC heat sink conception mainly contains two classes:
One class is the needs according to system radiating, adopts the mainboard of customization, makes being arranged with of weight reducing PC main frame internal part be beneficial to heat radiation, thereby makes distinguished and admirable being optimized of system improve the heat-sinking capability of entire system with this.The shortcoming of this method maximum is to have adopted too much custom component, can make the cost of complete machine significantly raise so on the one hand, and the complete machine development risk is very high on the other hand, because it can't tackle the frequent upgrading and the switching of platform structure.At present, the weight reducing PC of various all-in-ones and employing external power supply mostly adopts this system radiating scheme.
An other class is simply general desktop computer miniaturization.Its major technology means are to give up extendability, adopt notebook parts etc.The shortcoming of this heat dissipation design scheme maximum is that the life cycle of system is too short.Owing to there is not prospective system radiating scheme, when cpu power promoted suddenly significantly, these designs just had to abandon comprehensively, and thus, the serious consequence of bringing is to tackle the frequent upgrading and the switching of platform structure.
Particularly, in the prior art, as shown in Figure 2, the structure of tradition weight reducing computer comprises cabinet side panel 1, power supply 2, cpu heat 3, power supply air inlet 4, mainboard 5, CD-ROM drive 6, floppy drive 7, heat radiation air inlet 8, hard disk 9, memory bar 10 and expansion slot 11.Wherein, power supply 2 is sides that are placed near the CPU position.Why this structure places a side near CPU to power supply, is in order to utilize the power supply fan exhausting, directly the heat that CPU sends to be taken to outside the cabinet.A kind of good solution of can yet be regarded as when lower or system does not need frequently to upgrade at cpu power.But very big at cpu power, and system is when needing frequent upgrading, traditional placement scheme just is faced with a heat dissipation problem that is very difficult to solve, and that is exactly the demand that the ventilation of power supply is difficult to satisfy system radiating.In order to satisfy the demand of system radiating, prior art has only this solution of the power supply of raising ventilation.
But, owing under the situation that the system noise restriction can't improve, increase the ventilation of power supply, having only the volume that increases power supply at the power supply fan rotating speed, this must bring the volume of total system to increase, thereby loses the weight reducing characteristics of weight reducing PC.
Summary of the invention:
The object of the present invention is to provide a kind of thin desk computer that is beneficial to heat radiation, it has radiating effect well, and the PC that can guarantee to reduce weight has enough life cycles, with the frequent upgrading of reply CPU and the frequent switching of system architecture.
The objective of the invention is to be achieved through the following technical solutions: a kind of thin desk computer that is beneficial to heat radiation, which comprises at least cabinet and be arranged on cabinet interior power supply, CPU, expansion slot, radiator fan and driver, wherein power supply and CPU are provided with at interval, lay respectively at host computer cabinet both sides.
The position of corresponding CPU is provided with air inlet, and the air inlet place is provided with wind guide tank, sets out the air port on the cabinet panel of the heating radiator place correspondence of CPU, so that shorten heat dissipation channel.
Further, the present invention is at another heat radiation air inlet of the corresponding internal memory of cabinet, CD-ROM drive or hard disk position, and its position can be arranged on left plate, right plate, front panel, top panel or the lower panel place of cabinet front portion, thereby constitutes of the present invention pair of heat dissipation channel.
According to the technique scheme analysis as can be known, the present invention is rational in infrastructure, has following advantage:
Decentralized power s, the parts that the CPU thermal value is big make radiating effect even, can independently solve the heat dissipation problem of heat radiation object.
2, it is bigger to leave the space of power supply for, has further promoted the space of system upgrade, thereby has prolonged the life cycle of system.
3, the path of CPU heat radiation air intake and air-out is all very short, in the ordinary course of things, the blast that produces by cpu heat fan self just can directly be discharged to the cabinet outside to hot blast, do not need extra system fan that hot blast is discharged cabinet, can reduce system noise like this and save the heat radiation cost.
4, internal memory, CD-ROM drive or Hard disk heat radiation are by other passage, and the present invention just has two heat dissipation channel designs, so the integral heat sink effect is more good.
In sum, the invention solves the heat dissipation problem of long-term puzzlement weight reducing PC, weight reducing PC of the present invention can reach the same with common PC, even surpasses the system radiating demand of common PC life cycle.

Embodiment
Describe implementation result of the present invention in detail below in conjunction with accompanying drawing and by specific embodiment.
Basic thought of the present invention is that the thermal source production part that each is main separates, and dispel the heat respectively, thereby the difficulty of reduction system radiating improves the effect of heat radiation.
The present invention is included in the known host computers of parts such as power supply, CPU, expansion slot, radiator fan and driver that are provided with in the cabinet at least, and wherein power supply and CPU are provided with at interval, lay respectively at host computer cabinet both sides.CPU and power supply are arranged on an end of cabinet, and driver, internal memory, hard disk parts are arranged on the other end of cabinet, and expansion slot is set in the middle of CPU and the power supply.
Specific embodiment can be as shown in Figure 1.CPU of the present invention is arranged on an end of cabinet, power supply 2 at the other end of cabinet away from CPU.Mainboard 5 is set near expansion slot 11 in the middle of power supply and the CPU.Because power supply places the other end away from the big CPU of thermal value, the heat radiation of power supply is just played an auxiliary effect for the heat radiation of CPU, the load of its heat radiation has only thermal values such as outer plug-in card on himself and hard disk 9, the expansion slot 11 and memory bar 10 less, and upgrading is not very frequent parts.So, the design difficulty of power supply reduces greatly, and owing to the component no longer of removing mainboard 5 outer volume maximums in power supply and CD-ROM drive 6 these two systems is constrained each other, the space of leaving power supply for is bigger, can further promote the space of system upgrade, thereby prolong the life cycle of system.
Cpu heat of the present invention 3 directly from the air inlet on the cabinet side panel 1 at heating radiator top 12 by wind guide tank 14 exhausting, then by with the nearest cabinet panel of heating radiator on air outlet 13 heat is discharged outside the cabinet.What therefore heating radiator of the present invention was drawn into cabinet from the outside is the cold air that does not pass through any preheating, and the Ta value of cpu heat 3 is very low, is equal to the temperature of outside air basically.So, the cpu heat 3 of same performance can give thermal value higher CPU heat radiation.Have again, because the path of air intake and air-out is all very short, in the ordinary course of things, the blast that produces by cpu heat fan self just can directly be discharged to the cabinet outside to hot blast, do not need extra system fan that hot blast is discharged cabinet, can reduce system noise like this and save the heat radiation cost.
The present invention's upgrading space in the future is very big, and is easy to upgrading.Because this layout makes the heat radiation of CPU be totally independent of the heat radiation of system, when cpu power constantly raises in the future, only need the upgrading cpu heat, therefore, the weight reducing computer of this layout has just obtained life cycle the same with the big system of ATX and the performance that is easy to upgrade.
Further, the present invention also has the air inlet 8 that independently dispels the heat at memory bar 10, floppy drive 7, CD-ROM drive 6 or hard disk 9 designs, forms dual channel system heat dissipation channel of the present invention.This air inlet has enough ventilation rates to get final product.Memory bar 10, floppy drive 7, CD-ROM drive 6 or hard disk 9 dispel the heat by this passage, and each parts heat in the computer is no longer transmitted mutually, can distribute effectively respectively.
The Temperature Distribution of internal system of the present invention is very reasonable, does not have the too high dead band of temperature to exist.And the efficient of cpu heat improves greatly.For example, CPU for a 75W, traditional product Ta is 45 degree, and Ta is 35 degree in the placement scheme of the present invention, the ceiling value of supposing cpu temperature is 70 degree, and the thermal resistance of traditional heat-dissipating device need reach 0.33 and could satisfy radiating requirements so, and in the solution of the present invention, heat radiator thermal resistance only need reach 0.47 and can satisfy the demands, and the radiating efficiency that is equivalent to cpu heat 3 has improved 40%.
It should be noted last that, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not breaking away from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
