The present invention can ensure that the CPU with a superhigh basic frequency works within the safe temperature range, and can also ensure that other main heating components on a main board, a hard disc and a plug-in card work within the safe temperature range, and thereby, the heat radiating problem of a desk type computer host can be solved.
Description
[technical field]
The present invention relates to a kind of distinguished and admirable control system that is used for the desk computer heat radiation.
[background technology]
Along with the computer CPU dominant frequency rises higher and higher, its heating power also constantly increases, and the heating power of forming the utility appliance of system is also increasing high always, so heat dissipation problem restricts to soaring formation of high-performance more desktop computer.The life-span of electronic product, according to the statistics of USAF aviation electronics research institute, the hot stall of electronic product (comprising computer) accounted for the over half of total breakdown along with the rising meeting of temperature is shortened sharp.Heat dissipation design bad computer the lighter frequently crash, and weight person burns out parts.
The heat dissipation design of traditional desktop computer generally is that heating radiator is set on CPU, and cpu fan is set in cpu heat top, rely on metal pedestal and most heat radiator of cpu heat that the heat conduction that CPU sends is opened, blow off near the CPU by cpu fan then, via power supply or system fan heat is loose to the cabinet outside at last.
In addition, more existing passive heat radiation schemes have mainly been considered the heat radiation of CPU, and are fewer to the consideration of miscellaneous part in the system, do not carry out effective control to distinguished and admirable, make that actual radiating effect is not very desirable, so seldom adopted by system manufacturer.
The computer system producer that also has adopts the liquid cooling technology, the employing heat pipe technology that also has, but these technology cost height not only, and complex manufacturing technology, and reliability is not high is produced and maintenance all compare difficultly, and the possibility of through engineering approaches is lower.
[summary of the invention]
The object of the present invention is to provide the distinguished and admirable control system of a kind of solution based on the desk computer of the heat radiation of the desk computer of superelevation dominant frequency CPU, can guarantee that not only superelevation dominant frequency CPU is operated in safe temperature range, and can guarantee on the mainboard that other main heater elements and hard disk and plug-in card are operated in safe temperature range, thereby can really thoroughly solve the heat dissipation problem of desk computer.
In order to achieve the above object, the invention provides a kind of distinguished and admirable control system of desk computer, comprise cabinet and be installed in the system fan of air vent inboard set on the cabinet postnotum, it is characterized in that: in cabinet, be provided with wind guide tank, this wind guide tank has air inlet and at least two air outlets, this air inlet is set on the system fan, and this goes out the top that one's intention as revealed in what one says is located at installation CPU position in the cabinet, and another air outlet is towards the video card installation site.
Technical scheme of the present invention can also be replenished following technical characterictic:
The area of this wind guide tank air inlet is bigger, and the area of air outlet is less, and the air channel area of wind guide tank is to be to dwindle shape gradually from the air inlet to the air outlet, to improve wind speed.
Wind guide tank can be thin plastic sheet and makes by blow molding process, is fixed on the cabinet side board by double-sided tape.
This air vent is located at the postnotum middle part, also be provided with most louvres at this cabinet postnotum upside, correspondence is provided with power supply in the cabinet of this louvre inboard, on this postnotum, be fixed with air ducting, this air ducting comprises the lower baffle plate that is around in described air vent downside, be around in the side shield of this air vent side and surround arc cover plate around this louvre, is provided with thermovent at this cover plate upside.
This air ducting can be integrally moulded.
These fan board both sides are respectively equipped with grab, and are fixed on this air vent place of cabinet with this grab, and this fan board is provided with the side frame that system fan is surrounded, and this side frame engages with the air inlet periphery of this wind guide tank.
The distinguished and admirable control system of desk computer of the present invention has the advantage of the following stated:
It is that control is distinguished and admirable that wind guide tank of the present invention mainly acts on, and makes cold air directly blow to the main heat generating components of system.This wind guide tank structurally has two big characteristics: the one, and it has a plurality of air outlets, can cool off the bigger parts of a plurality of thermal values simultaneously; The 2nd, its each air channel area is to be to dwindle shape gradually from the air inlet to the air outlet, can play and quicken and concentrate distinguished and admirable effect.
The main effect of air ducting 40 of the present invention is to isolate cold air and hot-air, and the hot air reflow of avoiding extracting out from system forms distinguished and admirable short circuit in system.
As shown in Figure 3, the main effect of system fan frame 21 is that extraneous distinguished and admirable of guiding enters wind guide tank 30 and do not produce and disperse, secondly this structure can also separate system fan 20 and wind guide tank 30 and cabinet 1, in order to avoid the vibration that fan 20 high speed rotating cause passes to cabinet 1 or wind guide tank 30 and be exaggerated, the noise that causes complete machine raises or is unusual.
The main effect of system fan 20 is that extraneous cold air is blown in the cabinet 1.System fan frame 21 that native system adopts and system fan 20 so can select the fan 20 of different size as required, can also adopt temperature-controlled fan with further control intake owing to be independent structures, reduce the noise of complete machine.
The distinguished and admirable control system of desk computer of the present invention can solve following two to three years, even the system radiating demand based on the CPU desktop computer of superelevation dominant frequency of longer time.After tested, adopt behind the distinguished and admirable control system of desk computer of the present invention the Temperature Distribution of internal system very reasonable, do not have the too high dead band of temperature to exist, and, for the CPU that Intel will release later in 2 years, its maximum temperature has only 65 degree, is lower than the 70 degree upper limits, 5 degree of regulation.
Design proposal specific implementation of the present invention is versatile and flexible, can satisfy manufacturer and the user diversified demand to desktop computer.
This air ducting 40 can be integrally moulded.Wind guide tank 30 can be thin plastic sheet and makes by blow molding process, is fixed on the cabinet side board by double-sided tape.Installation and processing is all very convenient, low cost of manufacture.
