Embodiment
See Fig. 2, show the DVR cabinet 200 of the embodiment of the present invention.This DVR cabinet 200 comprises front panel 210 and box body 220.
As shown in figs.3 a and 3b, cabinet 200 inside is provided with hard disk array 230, mainboard 240, power supply 250 and case radiation fan 260.It is inner near front panel 210 that hard disk array 230 is arranged in cabinet 200, and this hard disk array 230 comprises multiple hard disk, such as 8.Mainboard 240 is arranged in cabinet 200 near cabinet rear portion.Mainboard 240 is connected with functional module and the interface circuits such as CPU, internal memory, video card.Power supply 250 provides required electric energy for DVR, and it is arranged in cabinet near rear portion.Usually, power supply 250 has independent power supply heat sinking fan, and this fan is positioned at cabinet 200 near cabinet back.
As shown in FIGURE 3 E, the side of cabinet 200 is provided with case radiation fan 260.This case radiation fan is low-speed big-diameter tubeaxial fan, and its operation noise is lower and air quantity is larger.In order to strengthen radiating effect further, multiple fan can be set, such as two fans.As Fig. 3 E, position corresponding to fan 260 on cabinet sidepiece can arrange corresponding air vent 2601.This air vent 2601 can be hexagonal honeycomb shape air vent array, to increase ventilation and to keep the electromagnetic screen in cabinet 200.
At this, a general employing high speed fan in prior art.But the operation noise of high speed fan is large, adopts two low-speed big-diameter tubeaxial fans to replace a high speed fan both can meet air quantity demand, can reduce noise again.
The heat dissipation wind channel of the power supply 250 in cabinet 200 is described below.
See Fig. 3 F, power supply 250 has self radiator fan 2501, and the air-flow suction in its cabinet is discharged.But on the other hand, the case radiation fan 260 that cabinet 200 sidepiece is arranged, it is operationally discharged air-flow suction.Therefore, in order to the two strands of air-flows preventing the radiator fan 2501 of power supply and case radiation fan 260 from causing disturb mutually, in one embodiment of this invention, power supply 250 has independently heat dissipation wind channel.As shown in Figure 3 B, two kinds of dissimilar arrows represent the running route of air-flow in the air channels of two isolation respectively.Arrow with triangle is the air-flow in the heat dissipation wind channel of power supply 250.
In one embodiment, be provided with deep bead 270 around power supply 250, this deep bead 270 is kept apart power supply 250 and is formed independently heat-dissipating space with the other parts of cabinet inside.In order to make air-flow enter this heat-dissipating space, cabinet sidepiece is provided with air vent 280 (Fig. 3 D), and this air vent 280 makes the independent heat-dissipating space of power supply 250 communicate with cabinet outside.In order to increase ventilation, keep electromagnetic screen good in cabinet, air vent 280 is preferably set to hexagonal honeycomb shape air vent array simultaneously.Air-flow, under the swabbing action of fan 2501, enters independent heat-dissipating space from air vent 280, is finally discharged to surrounding environment from the radiator fan 2501 of power supply 250, and in the process, power supply 250 is cooled.
In order to guide the air-flow in the independent heat-dissipating space of power supply 250, as shown in figs.3 a and 3b, deep bead 270 is two sections of slab constructions of bending, and the bottom surface perpendicular to cabinet 200 is arranged.One end of deep bead 270 be connected to there is air vent 280 case side wall on, the other end is connected to cabinet dorsal part.Thus, the spigot surface 2703 (Fig. 3 B) of deep bead 270 makes the air-flow entered from the air vent 280 of cabinet 200 sidepiece turn to the power supply 250 at cabinet 200 rear portion, and this deep bead 270 makes power supply 250 surrounding form the independently heat-dissipating space of isolating with cabinet inside other parts simultaneously.
In order to the connection of power supply 250 to the other parts in cabinet, deep bead 270 is provided with cable passage 2701.The top of this cable passage 2701 is set to opening mode, enters to facilitate cable.Usually, deep bead 270 is sheet metal part, and in order to prevent the sharp edges damage cable of cable passage 2701, the periphery of cable passage 2701 is provided with cable guard ring 2702, and this guard ring is such as caused by plastics.The upper opening part of cable guard ring 2702 can be provided with elasticity blend stop, so that cable is pressed into cable passage 2701 by elasticity blend stop or takes out from cable passage 2701, and does not need the threading in connection procedure to operate.
The heat dissipation wind channel of the hard disk array 230 and mainboard 240 etc. in cabinet 200 is described below.
The front panel 210 of cabinet 200 is provided with multiple ventilation slot 2101, and it is communicated with cabinet inside and ambient atmosphere.The set-up mode of this ventilation slot 2101 is, under the prerequisite not affecting other element on front panel, arranges the ventilation slot of greater number as much as possible, to increase ventilation.
See Fig. 3 B, the heat dissipation wind channel not having the arrow line of triangle to schematically illustrate hard disk array 230 and mainboard 240 flows to.
When case radiation fan 260 works, air-flow enters cabinet inside through ventilation slot 2101 on front panel, and moves towards fan 260.Hard disk array 230 on this gas channel and mainboard 240 etc. are cooled by air-flow successively.
Thus, the heat dissipation wind channel of power supply 250 and the heat dissipation wind channel of hard disk mainboard separate, avoid air-flow and mutually disturb the radiating efficiency that causes to reduce and noise increase.Meanwhile, when being provided with metal windshield 270, also avoid the electromagnetic interference (EMI) of other electronic unit in power supply 250 pairs of cabinets 200, enhancing the reliability of system.
As shown in Figure 4, CD writer 230 ' can be comprised in the position of hard disk array 230.This CD writer 230 ' is arranged on the anterior position near front panel 210 of cabinet 200 by the mode of Substitute For Partial hard disk.The heat radiation of this CD writer 230 ' is identical with the heat radiation of hard disk array 230, is not described in detail in this.
Above-described feature of the present invention can be used alone or in combination, and it is described with the form of embodiment, does not form the restriction to scope of the present invention.Any amendment done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
