The present invention ensures that the CPU with a superhigh basic frequency, other main heating components on the main board, the hard disc and the plug-in card work within the safe temperature range, and a powerful desk type computer host system with a small size can be designed.
Description
Technical field
The present invention relates to the Computer System Design field, relate more specifically to a kind of desk computer that adopts direct heat radiating layout system structure.
Technical background
At present, Intel and AMD have all released the CPU of dominant frequency more than 1.0GHz, but because the heating power of itself is very high, the heating power of the miscellaneous part that matches with it is also very high, so up to now, bulky superelevation dominant frequency desk computer also can only be provided on the market, manufacturer computer can't provide based on the CPU of superelevation dominant frequency, the powerful and small and exquisite host computer of volume, superelevation dominant frequency integral machine also can't be provided, can't satisfy people the diversified demand of desktop computer.
The appearance of this situation, relevant with traditional desk computer heat radiating layout system structure limitation.The design of traditional desktop computer system radiating generally is to rely on the metal pedestal of cpu heat that the heat conduction that CPU sends is opened, and blows off near the CPU by cpu fan then, via power supply or system fan heat is loose to the cabinet outside at last; The employing passive heat radiation scheme that also has directly blows to outside cold wind on the CPU radiating fin, and then is discharged to the outside through power supply or system fan.But in these processes, distinguished and admirable change direction through repeatedly produces a large amount of backflows inevitably, and the efficient of heat radiation is not high, so that the volume of total system is too huge.
In order to solve this limitation of traditional desktop computer system radiating design, the computer system producer that also has adopts the liquid cooling technology, the employing heat pipe technology that also has, but these technology are the cost height not only, complex manufacturing technology, and reliability is not high, produces and keeps in repair and all compare difficulty, and very be difficult to accomplish that volume is small and exquisite yet.
Summary of the invention
The object of the present invention is to provide a kind of desk computer that adopts single flow cooling system layout structure, it can guarantee on superelevation dominant frequency CPU, the mainboard that other main heater elements and hard disk and plug-in card are operated in safe temperature range.Utilize this system layout structure, can design varied large-scale production that is easy to, cost is low, and the reliability height meets the ergonomics requirement, and the small and exquisite desk computer system of volume.
For realizing the purpose of foregoing invention, a kind of desk computer that adopts direct heat radiating layout system structure is provided, include mainboard, central processing unit, memory bar, chipset, hard disk, outer plug-in card and system fan parts, it is characterized in that: at least one system fan is arranged at a side of mainframe box; Air outlet be arranged on mainframe box with system fan over against opposite side; And the extrapolation draw-in groove in this desk computer is parallel to the direction of the heat dissipation channel that forms between system fan and the air outlet in the direction that is provided with on the mainboard.
Preferably, this desk computer is provided with two system fan.
Preferably, system fan is arranged on the side of close central processing unit of mainframe box.
Preferably, the length of the heat dissipation channel that forms between this system fan and the air outlet equals the length of mainboard.
Preferably, the hard disk in this desk computer is set at mainboard top, near the air outlet of the rear end of the heat dissipation channel that forms between system fan and the air outlet.
The invention solves the CPU based on the superelevation dominant frequency, the heat dissipation problem of the desktop computer of small size of systems utilizes this technology, and it is less to design size, and the very powerful desk computer system of function.
By below in conjunction with the detailed description of accompanying drawing to specific embodiments of the invention, above and other purposes of the present invention and advantage will become obviously, in the accompanying drawing:
Description of drawings
Fig. 1 is the direct heat radiating layout system structure synoptic diagram according to the desk computer of embodiments of the invention 1;
Fig. 2 is the cfdrc sunykatuib analysis synoptic diagram to the P4 NorthWood-478FMB1 that adopts Intel of the present invention.
Embodiment
As shown in Figure 1, show direct heat radiating layout system structure according to the desk computer of embodiments of the invention 1.
As shown in Figure 1, one side of the installation central processing unit 5 of mainframe box is provided with two identical or different system fan 1 and 2, and mainframe box with these two system fan 1 and 2 over against opposite side be provided with air outlet 3, system fan 1 and 2 directly blows to the cold air of system outside on the heat radiator 6 of central processing unit 5 like this, is discharged to outside the cabinet by the air outlet 3 over against fan 1 and 2 then.The entire heat dissipation passage does not pass through any changed course, is the shortest path, so be referred to as the single flow heat radiation.
And as shown in Figure 1, the length of this heat dissipation channel equals the length of mainboard 4, thereby has reduced the size of desk computer greatly.
And as shown in Figure 1, system fan 1 and 2 is arranged on the side of installation central processing unit 5 of mainframe box, thereby makes the cooling effect of central processing unit better.
And, as shown in Figure 1, extrapolation draw-in groove in this desk computer the direction that is provided with on the mainboard 4 be parallel to system fan 1 and 2 with air outlet 3 between the direction of heat dissipation channel of formation, thereby make outer plug-in card can not form the obstruction that air-flow in the heat dissipation channel is advanced, further improve cooling effect.
And as shown in Figure 1, the hard disk 7 in this desk computer is set at mainboard 4 tops, system fan 1 and 2 and air outlet 3 between near the air outlet 3 of rear end of the heat dissipation channel that forms.Like this, the cold air top that system fan 1 and 2 is brought from the outside can directly arrive hard disk 7, makes the cooling of hard disk 7 reach best effect.
The single flow cooling system layout structure of present embodiment has solved the heat dissipation problem of the main heater element of system dexterously, and can make volume big or small the same with mainboard almost of system, and with low cost, the dirigibility height.
That shown in Figure 2 is the result who utilizes the computational fluid dynamics software sunykatuib analysis for the P4 NorthWood-478FMB1 (more than the dominant frequency 3G) that adopts Intel of the present invention.
As can see from Figure 2, the air-flow of system almost has no to have discharged outside the cabinet with hindering, and system's maximum temperature is the Tcase=67 degree of central processing unit, satisfies the requirement (70 degree) of Intel fully.
Be described in the mode of specific embodiment though should be appreciated that the present invention, be not limited to described specific embodiment, also comprise the possible modification and the change that are not separated with principle of the present invention and spirit.As applying the present invention to non-desk computer; As by adopting integral chip, can also design the littler desk computer system of volume based on this invention; As in conjunction with LCD, can design liquid crystal integral machine based on this invention; Also can change single system fan etc. into as double-system fans.
