Abstract
The utility model discloses a digital video recorder, which comprises a first fan (3) and a second fan (5), wherein the wind direction of the first fan (3) is from the outside to the inside of a chassis of the digital video recorder. The digital video recorder further comprises a wind board arranged around a power supply, wherein the power supply (1) and wind holes on the left side panel of a main tank are separated from a main board (2) and a hard disk (4) by the wind board (6). In the digital video recorder, the wind direction of the first fan is from the outside to the inside of the chassis of the digital video recorder with relatively large air inlet amount, and the power supply and the wind holes on the left side panel of the main tank are separated from the main board and the hard disk by the wind board; therefore, the wind incoming from the first fan is not discharged out from wind holes on the left side panel and a back side panel but is discharged out from wind holes at the front side panel close to the hard disk. Compared with the prior art, the digital video recorder has the advantages that the wind amount passing through the hard disk in the digital video recorder is relatively large, and the radiating effect of the hard disk is better.
Description
Technical field
The utility model relates to technical field of electronic equipment, relates in particular to a kind of digital hard disc video recorder.
Background technology
DVR (Digital Video Recorder), i.e. digital hard disc video recorder, it is the computer system that a cover carries out the image stores processor, have to image and voice record a video for a long time, the function of recording, telemonitoring and control.Generally, all to carry out heat dissipation design to digital hard disc video recorder for reliability that improves digital hard disc video recorder work and the serviceable life that prolongs digital hard disc video recorder.
For digital hard disc video recorder, mainly be to dispel the heat to its mainboard, hard disk and power supply.Shown in Fig. 1-4, generally on the sidewall around the cabinet of digital hard disc video recorder, wind hole A is set all, be provided with first fan near the cabinet sidewall of mainboard, the sidewall near hard disk of power supply is provided with second fan simultaneously.
In the prior art, the design of heat radiation generally has two kinds, and is as shown in Figure 5; Wherein a kind of is that the wind direction of first fan 03 is for blowing to the outside from the cabinet inside of digital hard disc video recorder; And the wind direction of second fan 05 is for being blown into power supply 01 back from power supply 01 front, this moment cabinet front panel and the left panel air intake of cabinet, the right panel of cabinet is near the position and the air-out of power supply place of mainboard 02; The distance of fresh air inlet distance first fan 03 and second fan 05 that front panel then is set like this is all far away; So the intake of the air inlet of front panel is less, less through the air quantity of hard disk 04, be unfavorable for heat radiation to hard disk 04.When dispelling the heat in this way, the temperature of hard disk 04 is analyzed, analysis result is that the maximum temperature rise of hard disk is about 12 ℃.
As shown in Figure 6, a kind of in addition be the wind direction of first fan 13 for blowing to inside from the cabinet outside of digital hard disc video recorder, and the wind direction of second fan 15 is for being blown into power supply 11 back from power supply 11 fronts; The left panel of cabinet and right panel are near mainboard 12 place's air intakes at this moment; Front panel and rear panel air-out are provided with the wind that then gets into from right panel like this and have part plate discharge from behind, thereby make through the wind of hard disk 14 less; Unfavorable to dispelling the heat equally; When dispelling the heat in this way, the temperature of hard disk 14 is analyzed, analysis result is that the maximum temperature rise of hard disk 14 is about 14.3 ℃.
In sum, how a kind of digital hard disc video recorder being provided, thereby making it solve the relatively poor problem of radiating effect of the inner hard disk of digital hard disc video recorder effectively, is present those skilled in the art's urgent problem.
The utility model content
In view of this, the purpose of the utility model is to provide a kind of digital hard disc video recorder, and the structural design of this digital hard disc video recorder can solve the relatively poor problem of radiating effect of the inner hard disk of digital hard disc video recorder effectively.
In order to achieve the above object, the utility model provides a kind of digital hard disc video recorder, comprises first fan and second fan, and the wind direction of said first fan blows to inside for the cabinet outside from digital hard disc video recorder;
Said digital hard disc video recorder also comprises the wind deflector that is arranged at around the power supply, and said wind deflector separates the wind hole on the Left-Hand Panel of power supply and main tank and mainboard and hard disk.
Preferably, in the above-mentioned digital hard disc video recorder, the wind direction of second fan is for blowing to the power supply back from the power supply front.
Preferably, in the above-mentioned digital hard disc video recorder, said first number of fans is specially two.
Preferably, in the above-mentioned digital hard disc video recorder, the wind hole on the right panel of said digital hard disc video recorder is specially a plurality of equally distributed regular hexagons hole.
Preferably, in the above-mentioned digital hard disc video recorder, said wind deflector is specially sheet metal.
The digital hard disc video recorder that the utility model provides comprises first fan and second fan, and the wind direction of first fan blows to inside for the cabinet outside from digital hard disc video recorder; Digital hard disc video recorder also comprises the wind deflector that is arranged at around the power supply, and wind deflector separates the wind hole on the Left-Hand Panel of power supply and main tank and mainboard and hard disk.
Because the wind direction of first fan blows to inside for the cabinet outside from digital hard disc video recorder; Intake is bigger, and owing to wind deflector has separated the wind hole on the Left-Hand Panel of power supply and main tank and mainboard and hard disk, so can not discharge from the wind hole of Left-Hand Panel and rear side panel again from the wind of first fan entering; And can only discharge from the wind hole near the front panel of hard disk; So compared with prior art, the air quantity through hard disk in this digital hard disc video recorder is bigger, and the radiating effect of hard disk is better.When dispelling the heat in this way, the temperature of hard disk is analyzed, analysis result is that the maximum temperature rise of hard disk is about 7 ℃.
In sum, the digital hard disc video recorder that the utility model provided can solve the relatively poor problem of radiating effect of the inner hard disk of digital hard disc video recorder effectively.
