Shallow talk embedded labour accuses box structure design

IPC (Industry Personal Computer) abbreviation labour accuses machine, or hard disk videocorder, DVR (Digital Video Recording) . Labour controls computer is use below harsh environment, protect a gender to the Yi Wei of the product, medicinal powder cycle of hot, dustproof, product, even measure respect is having firm demand. When because this is in,design and choice labour accuse machine platform, more is an orgnaization designs of the consideration, just be the consideration that waits to function next. Labour accuses machine be being used below a lot of circumstances is to apply at a certain system in, because this often is placed,be in a certain equipment or go up frame. Because this has firmer demand to dimension. According to the use circumstance of the user, cent to go up posture is mixed wall hung two kinds of designs. Go up posture: High: ? Word Zhui?U (44MM*430MM*XX) , 2U (88*430*XX) , 3U, 4U (178MM*430MM * XX) , 5U, 6U, 7U, 8U, the height of a 1U is 44MM, other height is ordinal analogize. If the place below the graph shows: 4U labour accuses machine length: The length of international standard has two kinds of 450MM and 505MM, the specific requirement according to the client is OK still enlarge divides other length, for instance: 480MM, 500MM, 520MM, 530MM, 600MM; Among them the 90% above that the dimension box of 450MM~~520MM takes market demand; The action of lengthen box basically is to have the following 3: One is to install double CPU to come strong 12 " * 13 " advocate board, the length ability that must want 520MM is installed such big board; Another is to install industrial CPU to grow get stuck or the patulous space with the enough need such as the video wedge with long 300MM; The last it is to come loose the consideration of hot space, because some of monitoring user needs to install multichannel video,get stuck with many hard disk, for instance 64, 128 wait, 10 hard disk come loose very well with respect to need hot effect. Generally speaking, it is above the orgnaization design of 1U or 2U. Because box volume is limited, but the power comsumption of CPU is increased increasingly (newest P4CPU power comsumption already exceeded 100W) , because this interior comes loose,hot tasteful design turned a manufacturer into the biggest problem that face. And the orgnaization comes loose the technical actual strength that heated up the work force of the design to reflect a firm greatly. To 1U labour accuses machine, multi-purpose at taller to bulk requirement telegraphic domain, cooperate to go up mostly frame use, labour accuses aircraft manufacturer to pass PICMG1.

The bulk advantage that the CPU of 0 frameworks blocks, those who cooperate 1U height butterfly model motherboard, supportable highest 2 PCI get stuck endlong. Satisfy thereby certain the user requirement that wants card of compositive in 1U box certain and special norms. To 4U, the orgnaization of 7U is designed, because the bulk of box greatens, be faced with in narrow box medicinal powder hot element already was not main consideration element. Because how this uses box space reasonably to offer more driver bracket inside limited space, how to offer many patulous card chamfer, how to support double CPU card, how to resist vibration, how to safeguard the main consideration that waits for an element to turn an orgnaization into the design easily the element is wall hung: In addition, because certain equipment manufacturer needs a control center (IPC) place in its equipment. Because this controls the bulk of machine to labour,have relatively firm demand. Go up traditionally casing of 19 inches of engine accumulates posture to satisfy a requirement very hard basically, because this is aimed at demand of this kind of client, rolled out wall hung box. Grind for example China IPC - series of 6606/6608 hanging box. This kind of box because volume is minor, and apply an environment be in some equipment is interior, because this designs a concept,also coming loose again on heat and patulous function. Next graphs are IPC - the status of machine cabinet interior that 6806 application check platform in some. This we discussed labour simply to accuse the design above the dimension of machine, it is OK that labour accuses machine basis to apply demand whole to go up cent to go up big kinds two posture labour accuses machine and wall hung labour accuses machine, we will design from the orgnaization from the back medicinal powder hot, fight brace up, dustproof, safeguard easily, prevent EMC isogon to spend will discuss labour to accuse the unique character of machine together with everybody slowly. Wall hung box labour accuses hard disk of box interior structure to wear, does CD driver wear: ? Zhui of word of ability carbon Kou owes extensive of Zhi Ejian  to pledge cent of be good at F inspects eggplant band ㄊ character to extensive of street Zheng  word of Huang of  of act of to bang Lan is stupefied namely  of Lu of  fish hawk evil spirit dam of dark blue of word of Sao of the δ that strap Er just drips? of muddleheaded of  earnestly word, ; Motherboard: The norms of motherboard has a variety of; Main with advocate board standards will differentiate. Common advocate board can install commonly; Among them the box of length was to be not installed under 520MM 12 " *13 " Shuang Zhijiang is big board advocate board, the box ability that must want 520MM length is installed. Press check: Basically have fixed effect. The installation video that how prevents monitoring grows card, or when industrial CPU grows card, must want to secure long wedge, rock appears in using a process at the same time, not firm wait for a phenomenon. Hind of groove patulous: Have 7 chamfer or 14 chamfer two kinds; The use with the main backboard of 14 chamfer is clip of installation multichannel video, have some of large supervisory system for instance, want 64, or 128 when, must want to change the backboard of 14 chamfer; Labour accuses the heat conduction of box: Medicinal powder the rationality of hot structure is to matter to computational function to deny the main factor of steady work. At present the most effective box comes loose hot solution is to use interactive medicinal powder hot passageway structure comes loose hot: Air of exterior low temperature by fan of ball of high speed of box forehead 120mm and box two side come loose hot aperture is inspiratory enter box, through chip of bridge of all sorts of chip of bridge of hard disk wearing, north and south, board card, north, arrive at CPU finally around, after passing CPU radiator, hot air one part from the ball of two 80mm high speed with hind box exhaust fan takes out box, additionally one part carries box of eduction of power source fan. Box fan uses ball fan, its advantage is wind force big, rotate speed is tall, calorific little, life long, noise is low, had avoided big noise, came true truly " green " medicinal powder hot. What labour accuses box is aseismatic: Labour accuses box when working, when because the many fan in the CD driver of box interior, hard disk, box are in,high speed runs, metropolis generation shakes, and shake to bring about CD misread and down to of attaint of hard disk track very easily to lose data, a structure that so the aseismatic sex of box also is our box key devises plan. Fight because of what consider box corrode, electric, heat conduction the internal demand that wait, our box damping system uses metallic stuff to be made entirely, this does damping to be able to not achieve afore-mentioned requirements solely than reinstate balata material, still can rise to fight ageing, the action such as heat-resisting. We the solution of this damping system got domestic and international client reputably. Labour accuses industry of box interior construction to dominate the electromagnetism screen of box: When our lead plane is working, advocate board, CPU, memory can produce many electromagnetism radiation with all sorts of board card, if be not added,also can cause certain harm in order to be on guard to human body. This moment box became screen electromagnetism radiate, protect our healthy main defense line. The box with good screen cuts off effectively exterior radiate interference, make sure computer interior fittings does not suffer exterior radiate effect. Labour accuses box to come loose to increase hot effect, the essential part on box is met starting a hole, include fan of aperture of casing side panel, bleed to enter wind aperture and aperture of wind of exhaust fan platoon to wait a moment, so the appearance of aperture must be accorded with can resist radiant technology demand. The starting a hole on box wants as far as possible small, and should use as far as possible cut off the round hole with radiant energy more powerful force. Next, want to notice the electromagnetism screen of all sorts of indicator light and switch wiring. Than longer jumper need designs skeining thread, line of two end solder barely metallic part needs the collar for a horse that use gum is wrapped, also avoided the electromagnetism radiation that produces with electrical wiring road inside box so.
