Next, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows a first embodiment of the silent hard disk drive apparatus of the present invention. In this embodiment, an embodiment in which a 2.5 inch hard disk drive is used among 2.5 inch hard disk drives and 3.5 inch hard disk drives generally standardized in the market is shown. Reference numeral 101 denotes a mounting bracket for mounting the silent hard disk drive device to a personal computer or an image recording device. Both ends of the mounting bracket 101 are bent, and the rubber container member 131 is disposed with the bent portion as a wall. Next, the rubber bottom member 103 is disposed so that the bottom and top surfaces of the 2.5-inch hard disk drive are in close contact with each rubber member. Further, a side rubber member having a recording disk, a motor, a read / write head, and an electronic circuit board on the rubber bottom member 103 is provided in a metal container so that the side surface of the main part 109 of the 2.5 inch hard disk drive is in close contact with the rubber member 105 is arranged. A main part 109 of the hard disk drive is mounted in a recess formed by the rubber bottom member 103 and the side rubber member 105. The hard disk drive main part 109 is covered with a rubber top member 107 and the hard disk drive main part is completely covered with rubber so that the sound generated from the internal motor and disk can be cut off.

  Bonding between the rubber members is performed with an adhesive, and bonding between the mounting bracket 101 and the rubber member is performed with the nut 111 and the mounting bracket embedded in the rubber when the hard disk drive device is mounted on a personal computer or an image recording device. The bolt hole 113 of 101 is aligned, and the nut 111 is fixed by attaching the bolt 115. A long heat pipe 121 is disposed in close contact with the hard disk drive main part 109 between the rubber top member 107 and the hard disk drive main part 109. The long heat pipe 121 uses a heat conductive sheet having high adhesion even if there is a slight depression in the adhesion of the metal container of the main part 109 of the hard disk drive. Also, silicon grease can be used if the gap can be filled. The other end of the long heat pipe 121 protrudes outside the rubber member. On the opposite side of the hard disk drive main portion 109 of the rubber top member 107, a lid 123 made of a material having good thermal conductivity such as a copper plate is fixed by a bolt 125 and a nut 127 embedded in the rubber top member 107. A long heat pipe 121 protruding outside the rubber member is in close contact with the lid 123. As a result, the heat accumulated in the rubber member is transferred to the outside by the heat pipe 121 and propagated to the lid 123 to dissipate heat, thereby preventing the hard disk drive device from being destroyed by heat. Also, since the signal and power cables are made of soft rubber, the soft rubber member is deformed according to the shape of the cable and is in close contact with the cable even if it is connected from any contact portion between the soundproof rubber members. Therefore, the soundproofing effect hardly changes.

  In this embodiment, in order to provide soundproofing for a 2.5 inch hard disk drive standardized in the market, the soundproofing members 103 and 107 are added to the 3.5 inch hard disk drive standardized in the market. It can also be used for 5-inch hard disk drives. That is, the cost can be reduced by sharing the main parts for the 2.5-inch hard disk drive and the 3.5-inch hard disk drive.

  In this embodiment, a 2.5-inch hard disk drive and a 3.5-inch hard disk drive device that are made into common parts are shown. However, even if a soundproof member dedicated to a 2.5-inch hard disk is manufactured, the metal container itself of the hard disk drive is soundproofed. You may manufacture with a member.

FIG. 2 shows a second embodiment of the present invention.
201 is a hard disk drive device covered with a soundproof member, and 203 is a heat pipe for propagating heat from the inside of the soundproof member to the outside. Fins 205 are in close contact with the heat pipe, and the heat dissipation efficiency is improved.

FIG. 3 shows a third embodiment of the present invention.
Reference numeral 301 denotes a hard disk drive device covered with a soundproofing member, and reference numeral 307 denotes a heat pipe for transmitting heat from the inside of the soundproofing member to the outside. The heat pipe 307 is in close contact with the electric / electronic device casing 305 containing the hard disk drive device with another heat pipe 303 via a heat conductive sheet or silicon grease. The heat dissipation efficiency is increased by conducting the heat of the hard disk drive device.

4 and 5 show an embodiment of the heat pipe.
The fine hole tunnel plate type heat pipe according to this embodiment is constituted by a meandering fine hole tunnel plate type heat pipe or a parallel fine hole tunnel plate type heat pipe as shown in FIGS. The meandering pore tunnel plate type heat pipe or the parallel pore tunnel plate type heat pipe uses a porous flat tube of light metal such as aluminum or magnesium. The porous flat tube 51 (61) has a flat outer shape as a whole, and a large number of through-holes 57a and 57b (68a and 68b) arranged in parallel are formed by extrusion molding. The partition wall on the end face of the through-hole is cut by a predetermined depth, and the opposite end face is also cut. The pores communicate with each other at the end portion to form a heat medium passage, which becomes a meandering tunnel or a parallel pore tunnel, in which a working fluid is sealed.

Here, the meandering capillary heat pipe is a heat pipe having the following characteristics (refer to Japanese Patent Laid-Open No. 4-190090).
(1) Both ends of the narrow tube (heat medium passage) are connected and sealed so as to be able to flow with each other.
(2) The part with the thin tube is the heat receiving part, and the other part is the heat radiating part.
(3) The heat receiving portion and the heat radiating portion are alternately arranged, and a narrow tube meanders between the two portions.
(4) A two-phase condensable working fluid is sealed in the narrow tube.
(5) The inner wall of the narrow tube has a diameter equal to or smaller than the maximum fluid diameter that allows the working fluid to circulate or move while always closing the inside of the tube.
By using such a thin tube heat pipe, heat transport can be performed regardless of the attachment posture of the thin tube heat pipe to the heating element.

  By using the heat pipe, it is possible to configure a hard disk drive device that is hardly affected by the heat dissipation efficiency in the attitude of the hard disk drive device.

It is an assembly drawing of the first embodiment of the present invention. It is 2nd Example of this invention. It is an assembly drawing of the third embodiment of the present invention. This is a meandering capillary heat pipe used in the present invention. This is a parallel thin tube heat pipe used in the present invention. This is a conventional hard disk drive device.
