Abstract

PROBLEM TO BE SOLVED: To improve the cooling ability by letting air flow in a space provided between a drive part and a package part. SOLUTION: A spacer 106 has a function for forming a space between a drive part 102 and a package part 103 of a hard disk device and enlarging the areas of both the parts in contact with air. A screw 107 fixes the hard disk device and the base of an information processor 101 and fixes both the drive part 102 and the package part 103 through spacers 105 and 106. When a fan 104 for cooling is rotated, air is inhaled from an air inlet 101a of the information processor 101 and exhaled from an air outlet 101b. At such a time, inside the information processor 101, air flows through the routes of a space 108a between the upper surface of the information processor 101 and the drive part 102, a space 108b between the drive part 102 and the package part 103 and a space 108c between the base of the information processor 101 and the package part 103.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooling structure for a disk device such as a hard disk device used as an external storage device of an information processing device.

[0002]

2. Description of the Related Art A hard disk drive used as an external storage device of an information processing apparatus has a magnetic recording medium, a drive motor, and a voice coil motor, and has a standard box shape (3.5 inch type, 5 inch type). And the like, and a package unit (control unit) having a control circuit of the drive unit and a circuit for controlling an interface with the system device side. The package portion is in close contact with a relatively large surface of the drive portion.
Heat sources of the hard disk device include a motor rotation of a drive unit and electronic components of a package unit.

In such a hard disk drive, the heat generated by the hard disk drive prevents the electronic circuit of the hard disk drive itself from malfunctioning, or the installed magnetic recording medium, other mechanical components, electrical components, and electronic components. It is necessary to cool the hard disk drive in order to prevent components from deteriorating, reducing reliability, or shortening the service life.

As means for cooling the hard disk device, means for improving the cooling performance on the information processing device side, such as mounting a cooling fan on the information processing device on which the hard disk device is mounted, are widely known. In this case, installing a fan with a larger air volume increases the cooling efficiency.However, the cooling fan is a source of noise and increases power consumption. There is a limit to the pod rotation speed.

[0005] For these reasons, it is very important to provide a means for making the hard disk drive itself more easily cooled.

[0006] This method is disclosed in Japanese Patent Application Laid-Open No. 10-1196.
As shown in FIG. 0, there is a hard disk drive or the like having a propeller for cooling on a drive shaft of a drive motor.

As another method, as a conventionally known technique, there is a method in which the structure of the drive unit is made uneven so as to form a heat radiation fin so that the area of the hard disk device in contact with air is increased.

[0008]

As a technique for making a hard disk drive more easily cooled, the above-described method of providing a drive shaft with a propeller has a disadvantage that the structure becomes complicated and the manufacturing cost of the hard disk drive increases. is there. In addition, the method of forming the drive in the form of a radiation fin has a drawback that the size of the storage medium that can be built in is reduced due to the provision of the unevenness in the drive unit, which leads to a reduction in storage capacity.

An object of the present invention is to provide a hard disk drive cooling structure capable of improving the cooling performance of the hard disk drive while increasing the area in which the hard disk drive comes into contact with air while solving these problems. is there.

[0010]

In order to achieve the above object, a space is provided between a drive section and a package section of a conventionally integrated hard disk drive, and a hard disk drive which allows air to flow through the space. Cooling structure is used. According to this structure, both the drive section and the package section of the hard disk device have an increased contact area with air, and the hard disk device is more easily cooled.

Further, the package section and the drive section can be separated from each other, so that both the drive section and the package section of the hard disk drive have an increased contact area with air. Thus, a hard disk device that can be cooled more easily can be provided.

[0012]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram showing a first embodiment of the present invention.

In FIG. 1, reference numeral 101 denotes an information processing device having a built-in hard disk device; 102, a drive unit of the hard disk device; 103, a package unit of the hard disk device;
A spacer provided between the bottom surfaces of the information processing devices is shown. Reference numeral 106 denotes a spacer provided between the drive unit 102 and the package unit 103, which creates a space between the drive unit and the package unit of the hard disk drive. 107 is a screw for fixing the hard disk device and the bottom surface of the information processing device, and has a function of increasing the contact area with air.
Reference numeral 104 denotes a cooling fan that fixes both the drive unit 103 and the package unit 103.

When the cooling fan 104 rotates, air is sucked in from the air inlet 101a of the information processing apparatus 101 and discharged from the air outlet 101b. At this time, in the information processing device, the space (1) between the upper surface of the information processing device and the drive unit is set.
08a), the space between the drive section and the package section (10
8b), air flows through the path of the space (108c) between the bottom surface of the information processing device and the package unit, and the cooling efficiency of the hard disk device is improved.

In this figure, a space through which air flows is created by inserting a spacer between the drive section and the package section. This is because the drive section and / or the package section are provided with protrusions, and the space through which the air flows is provided. It may be provided. Further, in this figure, both the drive unit and the package unit are fixed with screws 107, but the method of fixing the drive unit and the package unit is not necessarily limited to this method. Although the hard disk device is fixed from the bottom in this figure, there is no problem if it is fixed from the side. Furthermore, in this figure, the package is mounted on the lower surface of the drive, but if air can flow between the drive and the package, the package may be mounted on the upper or side surface of the drive. No problem.

FIG. 2 shows a second embodiment of the present invention.
In this figure, the drive unit (20
2) and the package part (203) are mounted separately.
Reference numeral 208 denotes an interface cable between the drive unit and the package unit. Providing a space for air convection as in the embodiment of FIG. 1 is effective when the information processing apparatus does not have a sufficient height. In this figure, the package part (2
03) is shown in the horizontal direction, but may be mounted in another direction, for example, the vertical direction.

As described above, the structure of the hard disk drive has been described as an embodiment of the present invention. This is because the present invention is most suitable for application to a hard disk drive. -Needless to say, the present invention is suitably applied to a device having a drive unit that generates heat mechanically and a package unit that generates heat electrically, such as a ROM device and a DVD device.

[0019]

As described above, according to the present invention,
By improving the area where the drive unit and the package unit are in contact with air, it is possible to enhance the cooling performance of the hard disk device. As a result, there is an effect that a disk device that solves the heat generation problem can be mounted on the information processing device.
