DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a file slot structure of a personal computer, and more particularly to a structure for mounting files on a file chassis.

[0002]

2. Description of the Related Art Conventionally, personal computers (hereinafter, referred to as personal computers).
A personal computer) is equipped with a high-speed CPU (central processing unit), and a large-capacity memory is added to enable high-speed data processing. In addition, this personal computer is a high-speed PCI (Peripheral Component).
A high-resolution display is realized by installing a window accelerator board as a standard in an nt interconnect slot.

Some of the above-mentioned personal computers use a tower-type housing. Among the units housed in the tower-type housing, units having a large capacity include a motherboard, a file chassis, an expansion slot, a power supply and the like. is there. Of these, the file chassis is an important component occupying a lot of space.

The file chassis is directly fixed to the housing, and files are directly fixed to the file chassis by screws. The cooling fan maintains the rotation speed required for the maximum configuration regardless of the number of files installed.

As the configuration of the personal computer described above, there is a configuration disclosed in Japanese Patent Application Laid-Open No. 7-37376.
According to the technique described in this publication, a head disk assembly unit (hereinafter, referred to as HDU) is mounted on a head disk assembly unit box (hereinafter, referred to as HDU-BOX) that forms a rectangular tubular tunnel structure in units of four units. The HDU-BOX is attached to the apparatus in a configuration of two rows on the left and right and four rows on the top and bottom.

A power supply corresponding to the HDU-BOX is provided downstream of the cooling air flow path of the HDU, and shares a cooling fan. The HDU-BOX is a pair (hereinafter, referred to as a pair).
This is referred to as an additional DKU), and an arbitrary number of 1 to 8 units can be mounted. Cables including power supply cables to the additional DKU are arranged vertically and are unitized by cable ducts.

The HDU is mounted on the HDU-BOX via a leaf spring, and has a collective mounting structure for fixing the HDU-BOX to a frame. A part of the interface cable is taken into the HDU-BOX, and the housing mounting cable is deleted.

A power supply is mounted downstream of an HDU cooling air passage generated in the HDU-BOX, and a small diameter hole for cooling is provided on an outer wall of the power supply to cool the power supply using the HDU cooling air.

[0009]

In the above-mentioned conventional file chassis, since it is directly fixed to the housing, the CP
U and SIMM (Single Inline Memo)
In this case, an area for performing replacement or extension of a new module is closed, making it difficult to replace or extend the module.

Further, since the file chassis is directly fixed to the housing, when the housing is installed on the floor, the working position is lowered, and it becomes difficult to exchange or add files. Sometimes. Furthermore, the main purpose is to fix the file slot, and the noise, the temperature, and the EMC (Electro Magnetic Com.
(patibility) is not taken into account.

On the other hand, in the technology described in the publication, one cooling fan is always mounted on one HDU, and the number of mounted HDUs increases, so that the number of cooling fans increases. The power consumption and the noise generated from the cooling fan increase proportionally, and at the same time, the cooling fan is mounted on the front side of the device, so that when the operator performs the operation, the generated noise is in a short distance, There is a problem that the loud noise gives an uncomfortable feeling to the operator.

Accordingly, an object of the present invention is to solve the above-mentioned problems, shorten the work time for exchanging and adding files, improve the maintainability, and
An object of the present invention is to provide a file slot structure of a personal computer capable of taking measures against noise, temperature, and EMC.

[0013]

cessing Equipment and Ele
(Ctronic Office Machines).

In the present invention, in order to solve the conventional problem,
In the file chassis structure and cooling method, the file chassis structure allows box-shaped units to be connected and separable, allowing replacement or removal of only expansion points, and expansion of signal and power cable connections. It can be done only by.

As a cooling method, all units are cooled by one cooling fan. Each unit is provided with a door, and when no file slot is added, the door remains closed. In addition to blocking the flow of the wind, when the expansion is performed, the tobira rotates and opens to secure the optimal flow path of the wind, and more air flows to the added file chassis side, so the cooling effect can be improved. It becomes possible.

By opening and closing the tobira depending on the presence or absence of a file slot and turning on / off (ON / OFF) a control switch attached to the housing side, the number of revolutions of the cooling fan is changed through the control unit to obtain an optimum air volume. And power consumption can be minimized. Therefore, the noise generated from the cooling fan can be reduced. This door also prevents electromagnetic waves from leaking,
It is also possible to achieve the CCI standard.

Further, in order to solve the problem of the conventional personal computer, a frame for receiving a file chassis is prepared in a housing, the file chassis is provided with a shape capable of mounting a plurality of files, and the entire file chassis is taken out from the housing. , And a space for adding or replacing CPUs and SIMMs.

When files are added or replaced by the user, the file chassis is taken out of the housing, and the file chassis is placed on an easy-to-work table so that the files can be added or replaced, thereby improving work efficiency. It is possible to do.
