Abstract
The utility model discloses a middle-mounted mainboard desktop computer host which mounts a mainboard at the middle part of a cabinet. An internal structure of a cabinet of the prior desktop computer is improved; a mainboard is divided into two parts (namely a big mainboard and a small mainboard), wherein, the small mainboard is arranged on the bottom of a cabinet, the big mainboard is arranged on the middle part of the cabinet, thus the mainboard is smartly arranged on the middle part of the cabinet and causes the cabinet to be divided into two parts, thereby obtaining higher extension performance and lower noise in a smaller cabinet.
Description
Technical field:
Computing machine
Background technology:
Existing desktop computer case structure has ATX and BTX, though BTX is being improved than ATX aspect arrangement of parts and the heat radiation, mainboard all is mounted in a side of cabinet, has caused the very big space waste of opposite side.And this design (especially ATX) can cause adverse effect to the video card heat radiation of high heat if do not use very many fans.Also have, existing minihose all is based upon under any sacrifice in performance and the extended capability, and space availability ratio is low equally.The mainboard that so mid-mainboard desk computer places the two sides in the middle of the cabinet all to adorn part can solve the low and bad problem of dispelling the heat of desktop computer cabinet inside space availability ratio.
Summary of the invention:
The installation of the two-sided mainboard of mid-mainboard desk computer is a very large problem, need the intensity of mainboard must be very big, the mainboard that but cooperates mid-mainboard desk computer is two-part, all respectively there is an aluminum alloy bar on the both sides that big mainboard contacts with cabinet, and the centre also has two horizontal stiffeners to play the effect of reinforcing mainboard.The mainboard of mid-mainboard desk computer does not need to reinforce with screw, only need be inserted into big mainboard slave box top in the groove of cabinet front and back during installation, and the Rubber washer in the groove can play fixing effect to mainboard.Little mainboard places below the cabinet, also only needs to insert the corresponding slot from the cabinet back just passable.In the central authorities of little mainboard, a slot is arranged, this slot is a data slot between little mainboard and the big mainboard for preceding half section, the second half section is the electric power output of power supply to mainboard.[Fig. 1-3]
There is the CPU slot in big mainboard front (left side), 4-8 memory bank, and north and south bridge chip and electric power system, the back side (right side) has other chip.What installed on the expansion slot left side between little mainboard and the big mainboard is the bar shaped power supply that directly is inserted on the little mainboard, and the right is the expansion slot of 4 standards, supports the expansion card of overall height, can use two top video cards of double flute of supporting SLi or Crossfire technology.The CPU of mid-mainboard desk computer, video card and power supply and north and south bridge chip do not need independent radiator fan, only need heat pipe, rely on 4 fans of cabinet front just can satisfy the heat radiation requirement.Because the mainboard separated into two parts, and mainboard is two-sided greatly, so the area of mainboard can reduce a lot.[Fig. 4-5]
The cabinet inside of mid-mainboard desk computer is without any cable, and what all adopt is hard connection, to reduce the fault that causes because of cable, has also eliminated the influence of cable to heat radiation.Because the power supply of mid-mainboard desk computer is directly to be connected with mainboard, so cabinet inside does not have power lead, all equipment all directly is connected with mainboard, obtains the electric energy of relevant voltage.Hard disk is to obtain electric energy and transmission data by the connector below the little mainboard, two CD-ROM drives at whole cabinet top are to lean on the slot at mainboard top to be connected with mainboard, two independent SATA interfaces and 4 pin D shape power interfaces are all arranged at the top of each CD-ROM drive in the mid-mainboard desk computer, interface on the other side is all arranged at the bottom, connects very convenient.The mainboard and the cabinet of mid-mainboard desk computer all are complementary, and being connected of the button on mainboard and the cabinet and USB, audio interface and card reader all is that interface by little mainboard side connects, and do not need cable equally.
The all hardware of mid-mainboard desk computer is the instrument of exempting from and installs, two mainboards all are direct-insert, expansion card is all fixing with clamp, each case fan is to install with the mounting means of the fan of similar Socket478CPU, and the mounting means of hard disk is similar to the hot plug hard disk support bracket.
The mainboard I/O interface of mid-mainboard desk computer is positioned at the back side of big mainboard, the middle part of whole back plate.Also reserved the installation site of 28 cm diameter fans on the backboard, to satisfy the heat radiation of higher demand.[Fig. 6]
Compare with common desk-top machine enclosure, under equal extended capability, (all support 8 internal memories, 2 CD-ROM drives, 4 expansion slot, 3 hard disks), mid-mainboard desk computer volume-diminished nearly 50%, and only need the radiator fan of 48 cm diameters just can satisfy the heat radiation requirement of top hardware.
If mid-mainboard desk computer is applied to server, and server do not need independent video card, and so big mainboard two sides can be used for CPU and internal memory are installed, and great extended capability is arranged.The server of having used mid-mainboard desk computer can reduce volume and weight effectively, is applicable to the demand of high-density deployment more.

Embodiment:
The critical piece of mid-mainboard desk computer such as CPU, internal memory, hard disk, various expansion card and existing desktop computer are basic identical, and just the heating radiator of CPU and video card needs to improve, and removes fan.The cabinet of mid-mainboard desk computer, mainboard and power supply are that prior art can be made fully, without any technical matters.The cost of mid-mainboard desk computer is compared much at one with existing desktop computer, and the extendability of the advantage that has more than the existing desktop computer of same volume arranged, desktop computer than same performance and extended capability has littler volume and lower noise, definitely can occupy windward in intense market competition.
