Abstract

The utility model relates to a computer without a fan. The utility model mainly uses a machine cabinet to conduct heat radiation, and a fan is canceled. High heating elements, such as a CPU, a power tube of a power supply and a display chip are attached to the machine cabinet, so the produced heat is transmitted to air by the machine cabinet. The computer of the utility model do not has noise produced by the fan, but has small size, high stability and good dedusting effect.

Description

No fan computing machine

The utility model relates to a kind of no fan computing machine, belongs to the computer hardware field.

Active computer particularly PC mostly uses Switching Power Supply, is one independently with the power supply box of heavy caliber fan.After 586 appearance, CPU mostly is with fan, and medium-to-high grade video card now also all uses fan to dispel the heat.Fan in the computing machine has certain effect for overclocking, raising thermal stability etc., but also brought a large amount of noises, certain electromagnetic radiation, and easily suck dust and cilium etc. in the air draft, influence the stability of computer-internal part, also easily make CD-ROM drive, floppy drive be infected with dust and break down.Fan moves easy break-down all the year round from as electromechanical structure.The heat radiator of band fan is all smaller and more exquisite, is difficult to reach original radiating effect after the fan stall, brings accident potential to complete machine.

The purpose of this utility model provides a kind of no fan computing machine, and the fan in the cancellation active computer utilizes computer cabinet to dispel the heat, and has also dwindled machine volume simultaneously.

The technical solution of the utility model is to take as the leading factor with the cancellation fan, at first power supply is moved on to the cabinet top, and all power tubes that need dispel the heat all invest the cabinet top board, suitably strengthen top plate thickness.Secondly CPU socket is moved to the bottom from mainboard top, make CPU be close to mainboard liner plate and cabinet side board, thereby make CPU that large-area heat radiation be arranged.Can suitably strengthen heat radiator for the common occasion of video card, need not use fan, the adopted heat-conducting plate that heat production is bigger links to each other the video card chip with cabinet side board, and heat is reached outside the cabinet.

Because adopt such scheme, computing machine can not contain fan, does not have the heat radiation noise, does not have the electromagnetic radiation of fan electromotor, can not be out of order because of the fan stall.Do not have air blast cooling, cabinet cleans relatively, and CD-ROM drive, floppy drive can be because of wind be stained with dust, and reliability strengthens, and the moistureproof dirt exclusion capabilities of complete machine increases, even use also Maintenance free in the relatively poor occasion of environment.Each heat producing components all has the large tracts of land heat sink behind the cancellation fan, further improves condition to thermal stability.Owing to cancelled original heat radiator and fan, machine volume is reduced, be beneficial to the development of portable machine.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is the common structural representation of active computer.

Fig. 2 is the main synoptic diagram of no fan computing machine, Fig. 3, Fig. 4 be respectively the A-A of Fig. 2 to, B-B to cut-open view, Fig. 5, Fig. 6, Fig. 7, Fig. 8 are the CPU position partial enlarged drawings of Fig. 3.

Fig. 9, Figure 10, Figure 11 are the hand-held computer synoptic diagram.

Sequence number and title explanation among the figure:

1, mainboard 2,4, three o'clock driver racks of 3, five o'clock driver racks of fan power supply

5, no fan power supply 6, CPU 7, cabinet top board 8, cabinet side board

13, CPU radiating fin and fan 14, CPU slot 15, panel 16, chassis lid

17, handle 18, panel cover

At first start with from power supply, active computer all has a Switching Power Supply, and Fig. 1 is a synoptic diagram, because the Power supply belt fan has the air draft effect, generally all designs the top at mainboard 1.Fig. 2 is a synoptic diagram of using no fan power supply instead, and no fan power supply 5 combines with cabinet top board 7, and the power pipe is close to the cabinet top board, strengthens the thickness of cabinet top board 7 simultaneously, and adopts dark colour, is beneficial to heat radiation.Because Switching Power Supply has bigger radiation, do not still have the lower panel sealing so there is fan power supply 5, power supply and cabinet inside are separated.

For the heat radiation of CPU, general thought is with the CPU underlying, just CPU is contained in below the mainboard, makes it to paste mutually with cabinet side board or base plate, utilizes case radiation.A-A cut-open view Fig. 3 from Fig. 2 discusses moving of CPU below, because the relative complete machine of CPU is less, we amplify the CPU place, and Fig. 5 to Fig. 8 is enlarged drawing, wherein Fig. 5, Fig. 6 are Slot1 or SlotA type CPU, and Fig. 7, Fig. 8 are CPU such as Socket series or 370 Celerons.For the purpose of clear, do not indicate parts among Fig. 5 to Fig. 8 fully, three vertical lines are represented mainboard 1, mainboard liner plate 9, cabinet side board 8 from left to right respectively among the figure.For Slot1 or SlotA type CPU, Fig. 5 is its conventional synoptic diagram, when we design mainboard, CPU slot 14 is placed in the below of mainboard, be illustrated right-hand, see Fig. 6, make CPU6 between mainboard liner plate 9 and cabinet side board 8, thereby make the CPU6 two sides all post the large-area metal plate, radiating effect is guaranteed.And for CPU such as Socket series or 370 Celerons, Fig. 7 is its conventional synoptic diagram, and after we moved to the mainboard opposite side with its slot, the CPU of insertion can directly paste with cabinet side board 8 mutually, sees Fig. 8, makes cabinet side board 8 become heat sink.For horizontal chassis, its mainboard directly is contained on the chassis backplane, and processing mode and above-mentioned form are similar.

It is the product of 3D processing requirements in recent years that video card uses fan, owing to will participate in a large amount of computings, the display chip temperature is higher, but non-fan also can be dealt with problems, Fig. 4 is that the B-B of Fig. 2 is to cut-open view, we use heat-conducting plate 10 that display chip 12 is linked to each other with cabinet side board, make the heat of display chip conduct to cabinet side board rapidly through heat-conducting plate, by large-area cabinet side board heat are dispersed in the air.Part is integrated mainboard video card is made on the mainboard, and its display chip can be moved to the mainboard another side, can reach radiating effect with processing as the Socket series CPU.

Because the measure of above-mentioned cancellation fan not only reaches radiating effect, and reduced space hold, and machine volume is dwindled greatly, Fig. 9 is the embodiment of an integrated application to hand-held computer shown in Figure 11.Fig. 9 is its panel, and Figure 10 is the vertical view of cabinet after opening wide, and mainboard uses integrated owing to adopt no fan structure, CPU and display chip all be contained in mainboard below, paste mutually with chassis backplane, duty is very little.Be equipped with 5

o'clock driver racks

3 and 3 o'clock driver racks 4 that desktop computer is used, make the main accessory of complete machine can be identical, change the shortcoming of portable computer accessory costliness with the desktop computer accessory.The complete machine side view is seen Figure 11, and is similar with notebook computer, and chassis lid 16 can be adorned LCDs, and keyboard can be adorned in cabinet top.After chassis lid 16 closed, panel cover 18 can cover panel 15, and the certain protection effect is arranged, and is portable when handle 17 is used to carry.
