Referring to accompanying drawing, the principle of work of heat abstractor provided by the utility model is described in detail.
Referring to Fig. 4, when utilizing heat abstractor provided by the utility model to dispel the heat, at the runner of three tangible wind of cabinet inside formation, wherein, the runner of first wind is:
Swabbing action by the radiator heat-dissipation fan, enter cold wind from second fresh air inlet suction of cabinet rear portion I/O interface top, swabbing action through radiator fan, after the cold wind that is aspirated dispels the heat to CPU through heat radiator, dispel the heat for north bridge, VRM and internal memory, these thermal components are realized becoming hot blast after the heat radiation, and a part of hot blast is discharged cabinet by second air outlet opening on cabinet right side; Wherein, at this cabinet is the horizontal-vertical double-purpose cabinet, and during vertical putting, the below of power supply one side of cabinet when to be that cabinet is vertical put, at this moment, because hot-air rises, the hot blast after CPU and VRM dispelled the heat is easy to discharge cabinet by second air outlet opening, thereby can make that the windage of heating radiator is very little, radiating effect is good;
The runner of second wind is:
Through another part air of heat radiator, under the swabbing action of cabinet left side power supply fan, flow to the cabinet left side, through the internal memory in the A district, internally deposit into the row heat radiation after, have power supply fan to pass through first air outlet opening discharge cabinet;
The runner of the 3rd wind is:
The circulation of this wind forms under the swabbing action of power supply fan, the air inlet of power supply fan is positioned at the front portion and the front portion, right side of power supply, owing to have video card to stop between power supply and power supply fan and the heating radiator, so hot blast some meeting through heat radiator is flowed to the cabinet left side, thereby, because the negative pressure that the swabbing action of power supply fan can be brought, this negative pressure can be compensated by the air of cabinet left side and cabinet front portion, thus, can make the cold wind that obtains from the external world by anterior first fresh air inlet of cabinet according to the flow direction shown in Figure 4 via hard disk, CD-ROM drive, floppy drive, and behind the thermal component such as video card, and power supply fan aspirates away, this cold wind is at the process hard disk, CD-ROM drive, floppy drive, and during thermal component such as video card, carry out heat interchange, thereby realize heat radiation to these parts, and after heat radiation, becoming hot blast, power supply fan is discharged cabinet with these hot blasts by first air outlet opening of cabinet back, thereby realizes heat radiation; The runner of this wind not only can be realized the heat radiation to hard disk, CD-ROM drive, floppy drive etc., can also realize by the cold wind video card of flowing through, and video card and other expansion card are realized thermolysis; Wherein, the runner of the 3rd wind makes outside cold wind earlier via hard disk, to hard disk dispel the heat the back power supply is being dispelled the heat, thereby after with respect to cold wind in the prior art CPU being dispelled the heat again to power supply this mode of dispelling the heat, can significantly reduce the EAT of power supply, thereby obtain great heat radiation effect power supply;
This shows, the runner of aforesaid first wind has been realized heat radiation to these core components of the CPU in the A district, VRM in the heat radiation process, the runner team of second wind has realized heat radiation to the internal memory in the A district, the runner of the 3rd wind has then been realized heat radiation to the peripheral components that comprises hard disk, CD-ROM drive, floppy drive and video card in the heat radiation process, utilize the runner of these three wind to can be good at realizing heat dissipation problem in the computer cabinet.
In other embodiment of the utility model, if because the needs of appearance design, the front of cabinet front portion can not be provided with first air vent, then first air vent can be arranged at the front portion of cabinet bottom surface, the space by between cabinet bottom and the desktop sucks cold wind from this bottom vents, can form the runner of aforesaid two wind equally, realize the heat radiation in the cabinet, therefore, the front portion that first air vent is arranged at the cabinet bottom surface does not influence realization of the present utility model.
