Description

本発明は、例えばパソコン等の電子機器の放熱構造、及び、部材取付構造に関する。   The present invention relates to a heat dissipation structure and a member mounting structure of an electronic device such as a personal computer.

例えばパソコン等の電子機器には、その内部にＣＰＵ、チップ部品、ＨＤＤ、及びＤＶＤドライブ等といった電子部品や装置等が配置されている。これらの電子部品や装置等は、電源電圧が供給されると内部に熱が蓄積し時間の経過につれて発熱するようになる。このような発熱部材から熱が放出されると、電子機器筐体内は、極めて高温になる。電子機器筐体内が高温になると、電子部品や装置等が誤動作してしまう原因にもなるため、通常、電子機器では、種々の発熱対策が実施されている。一般的には、発熱部材の近傍にファンを配置して、ファンによって空気の流路を形成することによって、発熱部材に冷たい空気を供給し、発熱部材を放熱させる。   For example, an electronic device such as a personal computer has an electronic component such as a CPU, chip component, HDD, and DVD drive, a device, and the like disposed therein. These electronic components, devices, and the like accumulate heat when a power supply voltage is supplied, and generate heat as time passes. When heat is released from such a heat generating member, the inside of the electronic device casing becomes extremely hot. If the temperature inside the electronic device casing becomes high, it may cause malfunction of electronic components, devices, and the like. Usually, various measures against heat generation are implemented in electronic devices. Generally, a fan is disposed in the vicinity of the heat generating member, and an air flow path is formed by the fan, whereby cold air is supplied to the heat generating member and the heat generating member is dissipated.

しかしながら、従来の電子機器では、発熱部材の数に応じて、多数のファンを使用しているので、コストが高くなるという問題点がある。また、電子機器としてのパソコンが音楽等の視聴を重視した構成とされる場合、上記従来のパソコンでは、多数のファンが駆動されることになるため、静音性が阻害されることになる。   However, the conventional electronic apparatus uses a large number of fans according to the number of heat generating members, and thus has a problem that the cost increases. In addition, when a personal computer as an electronic device is configured to place importance on viewing of music or the like, the conventional personal computer drives a large number of fans, which impedes silence.

また、ＨＤＤが駆動することによってＨＤＤが振動するが、その振動が、ＨＤＤが取り付けられている筐体等にも伝達され、筐体等が振動することによって、不要な騒音が発生するという問題もある。   In addition, when the HDD is driven, the HDD vibrates. However, the vibration is transmitted to a housing or the like to which the HDD is attached, and the housing or the like vibrates to generate unnecessary noise. is there.

筐体１は、前面パネル１１と、下部シャーシ１２と、後面パネル１３と、前面ブラケット１４と、側面シャーシ１５と、前面シャーシ２４と、図示しない天板とを有し、これらが組み合わされて筐体１が形成される。前面パネル１１は、例えばアルミニウムからなる。筐体１の内部であって前面パネル１１の裏側には、前面ブラケット１４や前面シャーシ２４が取り付けられている。   The housing 1 includes a front panel 11, a lower chassis 12, a rear panel 13, a front bracket 14, a side chassis 15, a front chassis 24, and a top plate (not shown), which are combined to form a housing. A body 1 is formed. The front panel 11 is made of aluminum, for example. A front bracket 14 and a front chassis 24 are attached to the back of the front panel 11 inside the housing 1.

図１〜図４に示すように、下部シャーシ１２には、アンプ部２、電源トランス３、および、マザーボード４等が取り付けられている。   As shown in FIGS. 1 to 4, an amplifier unit 2, a power transformer 3, a motherboard 4, and the like are attached to the lower chassis 12.

アンプ部２は、発熱部材の１つであって、ＨＤＤ５に記録されている音楽ファイルに基づいて再生された音楽信号、または、後面パネル１３に設けられた音声入力端子から入力された音声信号を増幅するものである。アンプ部２によって増幅された音声信号は、後面パネル１３に設けられたスピーカー端子に接続される図示しないスピーカーに供給され、音声として出力される。アンプ部２は、図４に示すように、下部シャーシ１２の上面であって、前方左側の位置に取り付けられている。   The amplifier unit 2 is one of the heat generating members, and receives a music signal reproduced based on a music file recorded in the HDD 5 or an audio signal input from an audio input terminal provided on the rear panel 13. Amplify. The audio signal amplified by the amplifier unit 2 is supplied to a speaker (not shown) connected to a speaker terminal provided on the rear panel 13 and output as audio. As shown in FIG. 4, the amplifier unit 2 is attached to the front left side position on the upper surface of the lower chassis 12.

電源トランス３は、発熱部材の１つであって、供給される交流電源電圧を１次巻線と二次巻線の巻数比に応じて変圧するものである。電源トランス３は、図４に示すように、下部シャーシ１２の上面であって、前方右側の位置に取り付けられている。   The power transformer 3 is one of the heat generating members, and transforms the supplied AC power voltage in accordance with the turn ratio of the primary winding and the secondary winding. As shown in FIG. 4, the power transformer 3 is mounted on the upper surface of the lower chassis 12 and on the front right side.

マザーボード４は、略矩形平板状に形成されたプリント基板によって構成されている。マザーボード４は、発熱部材の１つであるＣＰＵ、チップ部品、ヒートシンク、サウンドカード、及び、電源回路部品（コンデンサや抵抗等）等を搭載するものである。マザーボード４は、下部シャーシ１２の上面であって、後方側の位置に取り付けられている。   The mother board 4 is constituted by a printed circuit board formed in a substantially rectangular flat plate shape. The motherboard 4 mounts a CPU, a chip component, a heat sink, a sound card, a power circuit component (capacitor, resistor, etc.), etc., which are one of the heat generating members. The mother board 4 is attached to the upper surface of the lower chassis 12 at a position on the rear side.

マザーボード４の上方には、図２に示すように、略Ｌ字状に折り曲げられたダクト部材１０が設けられている。ダクト部材１０のマザーボード４に対向する開口には排気用ファン９が下部シャーシ１２に対して水平になるように取り付けられている。また、後面パネル１３には、ダクト部材１０の他方の開口に対向する位置に複数の排気口１７が形成されている。排気用ファン９およびダクト部材１０によって、筐体１内の暖められた空気は、排気口１７を介して筐体１の外部に放出される。   A duct member 10 bent in a substantially L shape is provided above the mother board 4 as shown in FIG. An exhaust fan 9 is attached to the opening of the duct member 10 facing the mother board 4 so as to be horizontal with respect to the lower chassis 12. The rear panel 13 is formed with a plurality of exhaust ports 17 at positions facing the other opening of the duct member 10. The warmed air in the housing 1 by the exhaust fan 9 and the duct member 10 is discharged to the outside of the housing 1 through the exhaust port 17.

なお、排気用ダクト９が直接、後面パネル１３の排気口１７の位置に取り付けられる場合には、ダクト部材１０は不要である。   In addition, when the exhaust duct 9 is directly attached to the position of the exhaust port 17 of the rear panel 13, the duct member 10 is unnecessary.

図１のように、ＨＤＤ５およびファン８は、ケース部材６の中に収納されており、ケース部材６は、側面シャーシ１５および前面シャーシ２４の上面に配された後に、カバー部材７によって上部の開口が覆われて、カバー部材７と共に側面シャーシ１５にネジによって結合される（詳細後述、図５〜図７参照）。   As shown in FIG. 1, the HDD 5 and the fan 8 are housed in a case member 6, and the case member 6 is disposed on the upper surface of the side chassis 15 and the front chassis 24, and then opened by the cover member 7. Is covered and joined to the side chassis 15 together with the cover member 7 by screws (see details below, see FIGS. 5 to 7).

図１〜図４のように、下部シャーシ１２には、前方端部に左右方向に広がるようにして複数の吸入口１６が形成されている。吸入口１６は、ファン８の吸引力に基づいて、外部の空気を筐体１内に吸入するためのものである。吸入口１６の形状および数は外部から吸入する空気の量に応じて任意の適切な形状及び数が採用され得るが、本例では長円形状の吸入口１６が９つ形成されている。また、限定されないが、下部シャーシ１２の裏面には図示しない脚部（又は、その他の、下部シャーシ１２をパソコン１００の設置面から浮かす手段）が取り付けられており、吸入口１６が塞がれないようになっている。また、アンプ部２や電源トランス３は、吸入口１６を塞がないように、吸入口１６よりもやや後方に取り付けられている。   As shown in FIGS. 1 to 4, the lower chassis 12 is formed with a plurality of suction ports 16 extending in the left-right direction at the front end. The suction port 16 is for sucking outside air into the housing 1 based on the suction force of the fan 8. Although any appropriate shape and number can be adopted as the shape and number of the suction ports 16 according to the amount of air sucked from the outside, nine oval suction ports 16 are formed in this example. Although not limited, a leg (not shown) (or other means for floating the lower chassis 12 from the installation surface of the personal computer 100) is attached to the back surface of the lower chassis 12, and the suction port 16 is not blocked. It is like that. The amplifier unit 2 and the power transformer 3 are attached slightly behind the suction port 16 so as not to block the suction port 16.

ケース部材６は、ＨＤＤ５を交換可能にするために、ＨＤＤ５を着脱可能に収納し、筐体１の側面シャーシ１５に着脱可能に取り付けられるものである。さらに、ケース部材６は、図３のように、ＨＤＤ５を放熱するための第１流路Ａ、および、アンプ部２および電源トランス３を放熱するための第２流路Ｂを形成するものである。ケース部材６は、図８〜図１３に示すように、その外形が、ＨＤＤ５やファン８を挿入可能なように上面に開口が形成された略直方体の箱状に形成されている。ケース部材６は、ＨＤＤ５が収納される略直方体の箱状のＨＤＤ収納部６ａと、ＨＤＤ収納部６ａの後方に連通、延設され、ファン８が収納されるファン収納部６ｂとを有する。また、ケース部材６は、ファン収納部６ｂの前方に連通、延設された筒状部６ｃを有する。なお、図８の左側はケース部材６にＨＤＤ５及びファン８が取り付けられた状態を、右側は取り付けられていない状態を示す。   The case member 6 detachably houses the HDD 5 so that the HDD 5 can be replaced, and is detachably attached to the side chassis 15 of the housing 1. Furthermore, the case member 6 forms a first flow path A for radiating heat from the HDD 5 and a second flow path B for radiating heat from the amplifier unit 2 and the power transformer 3 as shown in FIG. . As shown in FIGS. 8 to 13, the outer shape of the case member 6 is formed in a substantially rectangular parallelepiped box shape in which an opening is formed on the upper surface so that the HDD 5 and the fan 8 can be inserted. The case member 6 has a substantially rectangular parallelepiped box-shaped HDD storage portion 6a in which the HDD 5 is stored, and a fan storage portion 6b that communicates and extends behind the HDD storage portion 6a and in which the fan 8 is stored. The case member 6 has a cylindrical portion 6c that communicates and extends in front of the fan housing portion 6b. 8 shows a state where the HDD 5 and the fan 8 are attached to the case member 6, and the right side shows a state where the case member 6 is not attached.

ＨＤＤ収納部６ａの前面の例えば下側部分には、ＨＤＤ収納部６ａ内に吸入口１６からの空気を取り込むための、長方形状の開口６ｄが形成されている。また、筒状部６ｃの前面側には、吸入口１６からの空気を、ＨＤＤ収納部６ａを介さずに、アンプ部２や電源トランス３が配された領域を介して、ファン収納部６ｂ内に取り込むための開口６ｅが形成されている。ファン収納部６ｂの後面側には、ＨＤＤ収納部６ａからファン収納部６ｂに移動される空気と、筒状部６ｃからファン収納部６ｂに移動される空気とを、ケース部材６の後方に放出するための開口（ケース部材における排気口）６ｆが形成されている。なお、ＨＤＤ５およびファン８が取り付けられた後に、ケース部材６の上面にカバー部材７が結合されることによって、ケース部材６の上面開口はカバー部材７によって塞がれる。従って、ＨＤＤ収納部６ａを移動する空気が上面開口からほぼ漏れることはない。   A rectangular opening 6d for taking in air from the suction port 16 into the HDD housing portion 6a is formed in, for example, the lower portion of the front surface of the HDD housing portion 6a. Further, on the front side of the cylindrical portion 6c, the air from the suction port 16 is not passed through the HDD storage portion 6a, but through the region where the amplifier unit 2 and the power transformer 3 are arranged. An opening 6e for taking in is formed. On the rear surface side of the fan housing portion 6b, air that is moved from the HDD housing portion 6a to the fan housing portion 6b and air that is moved from the cylindrical portion 6c to the fan housing portion 6b are released to the rear of the case member 6. An opening (exhaust port in the case member) 6f is formed. After the HDD 5 and the fan 8 are attached, the cover member 7 is coupled to the upper surface of the case member 6, so that the upper surface opening of the case member 6 is closed by the cover member 7. Therefore, the air moving through the HDD housing 6a hardly leaks from the upper surface opening.

ファン８がファン収納部６ｂに収納されることにより、図１０に示すように、ファン８の一部（上側部分、例えば、上半分）は、ＨＤＤ収納部６ａ（ＨＤＤ５や開口６ｄ）に対向し、ファン８の他の一部（下側部分、例えば、下半分）は筒状部６ｃ（開口６ｅ）に対向することになる。すなわち、ファン８の上半分は、ＨＤＤ収納部６ａ内の空気を開口６ｆを介して外部に放出するように機能し、ファン８の下半分は、開口６ｅからの空気を開口６ｆを介して外部に放出するように機能する。その結果、ファン８を駆動させることによって、図３のように、以下の２つの空気の流路Ａ、Ｂが形成されることになる。   When the fan 8 is housed in the fan housing 6b, as shown in FIG. 10, a part of the fan 8 (upper part, for example, the upper half) faces the HDD housing 6a (HDD 5 or opening 6d). The other part (lower part, for example, lower half) of the fan 8 faces the cylindrical part 6c (opening 6e). That is, the upper half of the fan 8 functions to release the air in the HDD housing portion 6a to the outside through the opening 6f, and the lower half of the fan 8 has the air from the opening 6e to the outside through the opening 6f. Function to release. As a result, by driving the fan 8, the following two air flow paths A and B are formed as shown in FIG.

流路Ａは、下部シャーシ１２の吸入口１６から筐体１内に取り込まれた空気が、（アンプ部２や電源トランス３の位置を介さずに）開口６ｄを介してＨＤＤ収納部６内に吸入され、ファン収納部６ｂを介して、開口６ｆからケース部材６の後方に放出される流路である。流路Ａを流れる空気によってＨＤＤ５が放熱される。流路Ｂは、下部シャーシ１２の吸入口１６から筐体１内に取り込まれた空気が、（ＨＤＤ収納部６ａを介さずに）アンプ部２や電源トランス３の位置を介して、開口６ｅから筒状部６ｃ内に吸入され、ファン収納部６ｂを介して、開口６ｆからケース部材６の後方に放出される流路である。流路Ｂを流れる空気によって、流路Ｂ上に配されているアンプ部２や電源トランス３が放熱される。このようなケース部材６の構造を採用することによって、互いに分離された２つの流路Ａ、Ｂを形成することが本発明の特徴の１つである。   In the flow path A, air taken into the housing 1 from the suction port 16 of the lower chassis 12 enters the HDD housing portion 6 through the opening 6d (not through the position of the amplifier portion 2 or the power transformer 3). This is a flow path that is sucked and discharged from the opening 6f to the rear of the case member 6 through the fan housing 6b. The HDD 5 is radiated by the air flowing through the flow path A. The flow path B is such that air taken into the housing 1 from the suction port 16 of the lower chassis 12 passes through the opening 6e via the position of the amplifier unit 2 and the power transformer 3 (not through the HDD housing unit 6a). This is a flow path that is sucked into the cylindrical portion 6c and discharged from the opening 6f to the rear of the case member 6 through the fan housing portion 6b. The air flowing through the flow path B radiates heat from the amplifier unit 2 and the power transformer 3 disposed on the flow path B. By adopting such a structure of the case member 6, it is one of the features of the present invention to form the two flow paths A and B separated from each other.

なお、筒状部６ｃが設けられることにより、開口部６ｆから放出された空気が、前方側に回り込んで、再び開口部６ｅからケース部材６内部に吸入されることを防止することができる。すなわち、筒状部６ｃを設けることで、開口部６ｆから放出された空気は、後方に設けられたダクト部材１０内に取り込まれるようになる。   In addition, by providing the cylindrical portion 6c, it is possible to prevent the air released from the opening 6f from flowing around to the front side and being sucked into the case member 6 from the opening 6e again. That is, by providing the cylindrical portion 6c, the air discharged from the opening 6f is taken into the duct member 10 provided at the rear.

好ましくは、ＨＤＤ５は、図８〜図１３のように、ＨＤＤブラケット１８を介してＨＤＤ収納部６ａ内に取り付けられる。ＨＤＤブラケット１８は、ＨＤＤ収納部６ａ内でＨＤＤ５を支持するものであり、後述する第１防振部材１９および第２防振部材２０を介してＨＤＤ５をケース部材６に取り付けるものである。ＨＤＤブラケット１８は、図１２のように（左側はＨＤＤブラケット１８にＨＤＤ５が取り付けられた状態を、右側は取り付けられて以内状態を示す）、ＨＤＤ５の底面の形状に対応する略長方形状の底板部１８ａと、底板部１８ａの長辺部分からＨＤＤ５の方向かつ短辺方向外側に向かって断面略Ｌ字状に折り曲げられて延設されたＨＤＤ設置部１８ｂとを含む。つまり、ＨＤＤブラケット１８は、平面視した場合に略長方形状に形成されている。底板部１８ａは、ケース部材６のＨＤＤ収納部６ａの底面に結合される部分である。ＨＤＤ設置部１８ｂは、ＨＤＤ５が設置される部分である。底板部１８ａからＨＤＤ５までの間隔が、ＨＤＤ設置部１８ｂからＨＤＤ５までの間隔よりも大きくなっている。ＨＤＤブラケット１８がこのような形状を有することにより、ＨＤＤ５はＨＤＤ収納部６ａの底面から所定の高さだけ持ち上げられた状態で、ＨＤＤ収納部６ａに収納される。その結果、ＨＤＤ収納部６ａ内で空気の流路がＨＤＤ５自身によって塞がれることなく、ＨＤＤ５の下側部分に十分な空気の流路を形成することができる。なお、これに限定されず、底板部１８ａとＨＤＤ設置部１８ｂとが同一平面上に設けられても良い。   Preferably, the HDD 5 is mounted in the HDD housing portion 6a via the HDD bracket 18 as shown in FIGS. The HDD bracket 18 supports the HDD 5 in the HDD housing 6a, and attaches the HDD 5 to the case member 6 via a first vibration isolation member 19 and a second vibration isolation member 20 described later. The HDD bracket 18 has a substantially rectangular bottom plate corresponding to the shape of the bottom surface of the HDD 5 as shown in FIG. 12 (the left side shows the HDD 5 attached to the HDD bracket 18 and the right side shows the attached state). 18 a and an HDD installation portion 18 b that is bent and extended in a substantially L-shaped cross section from the long side portion of the bottom plate portion 18 a toward the HDD 5 and outward in the short side direction. That is, the HDD bracket 18 is formed in a substantially rectangular shape when viewed from above. The bottom plate portion 18 a is a portion that is coupled to the bottom surface of the HDD housing portion 6 a of the case member 6. The HDD installation unit 18b is a part where the HDD 5 is installed. The interval from the bottom plate portion 18a to the HDD 5 is larger than the interval from the HDD installation portion 18b to the HDD 5. Since the HDD bracket 18 has such a shape, the HDD 5 is housed in the HDD housing section 6a in a state where it is lifted by a predetermined height from the bottom surface of the HDD housing section 6a. As a result, a sufficient air flow path can be formed in the lower portion of the HDD 5 without the air flow path being blocked by the HDD 5 itself in the HDD housing portion 6a. However, the present invention is not limited to this, and the bottom plate portion 18a and the HDD installation portion 18b may be provided on the same plane.

好ましくは、図１２のように、ＨＤＤブラケット１８は、１又は複数の（本例では４つの）第１防振部材１９を介してケース部材６のＨＤＤ収納部６ａに取り付けられる。第１防振部材１９は、弾性を有しており、任意の適切な樹脂またはゴム等によって形成されている。第１防振部材１９は、径方向にやや肉厚の略円筒形状に形成され、その外周部において高さ方向の略中間位置に切り込み（図示せず）が形成されており、底板部１８ａの４隅に形成された円形の切り込み（図示せず）に挿入されて、底板部１８ａの４隅に取り付けられている。すなわち、第１防振部材１９が底板部１８ａを両側から挟み込むようにして、取り付けられている。第１防振部材１９の中空部内にケース部材６のＨＤＤ収納部６ａの底面から上方向に突出しているネジ止めボス６ｇ（図８参照）が挿入された後、ネジを上方向から螺合させることによって、ＨＤＤブラケット１８がケース部材６のＨＤＤ収納部６の底面に結合される。   Preferably, as shown in FIG. 12, the HDD bracket 18 is attached to the HDD housing portion 6 a of the case member 6 via one or a plurality of (four in this example) first vibration isolation members 19. The first vibration isolation member 19 has elasticity and is formed of any appropriate resin or rubber. The first vibration isolation member 19 is formed in a substantially cylindrical shape with a slight thickness in the radial direction, and a cut (not shown) is formed at a substantially intermediate position in the height direction on the outer peripheral portion thereof. It is inserted into circular cuts (not shown) formed at the four corners and attached to the four corners of the bottom plate portion 18a. That is, the first vibration isolation member 19 is attached so as to sandwich the bottom plate portion 18a from both sides. After the screwing boss 6g (see FIG. 8) protruding upward from the bottom surface of the HDD housing portion 6a of the case member 6 is inserted into the hollow portion of the first vibration isolation member 19, the screw is screwed from above. As a result, the HDD bracket 18 is coupled to the bottom surface of the HDD housing portion 6 of the case member 6.

ＨＤＤブラケット１８は、１又は複数の（本例では４つの）第２防振部材２０を介してＨＤＤ５が取り付けられる。第２防振部材２０は、弾性を有しており、任意の適切な樹脂またはゴム等によって形成されている。第２防振部材２０は、図１２のように、円筒形状（リング形状）に形成され、その外周部における高さ方向の略中間位置に切り込み（図示せず）が形成されており、ＨＤＤ設置部１８ｂの所定位置（ＨＤＤ５底面のネジ孔に対応する位置）に形成された円形の切り込み（図示せず）に挿入されて、ＨＤＤ設置部１８ｂの所定位置に取り付けられている。すなわち、第２防振部材２０がＨＤＤ設置部１８ｂを両側から挟み込むようにして、取り付けられている。ＨＤＤブラケット１８がケース部材６に結合されるとき、第２防振部材２０は、ＨＤＤ収納部６ａの底面から上方向に突出している略円筒のボス６ｈ（図８参照）の上に配されている。そして、ＨＤＤ５底面のネジ孔（図示せず）が第２防振部材２０の中空部上に位置するように、ＨＤＤ５が第２防振部材２０上に設置される。そして、ケース部材６のボス６ｈの下方向からネジを螺合させることによって、ＨＤＤブラケット１８にＨＤＤ５が結合される。   The HDD 5 is attached to the HDD bracket 18 via one or a plurality of (four in this example) second vibration isolation members 20. The second vibration isolation member 20 has elasticity and is formed of any appropriate resin, rubber, or the like. As shown in FIG. 12, the second vibration isolating member 20 is formed in a cylindrical shape (ring shape), and a notch (not shown) is formed at a substantially intermediate position in the height direction on the outer periphery thereof. It is inserted into a circular notch (not shown) formed at a predetermined position of the portion 18b (a position corresponding to the screw hole on the bottom surface of the HDD 5) and attached to a predetermined position of the HDD installation portion 18b. That is, the second vibration isolation member 20 is attached so as to sandwich the HDD installation portion 18b from both sides. When the HDD bracket 18 is coupled to the case member 6, the second vibration isolation member 20 is disposed on the substantially cylindrical boss 6 h (see FIG. 8) that protrudes upward from the bottom surface of the HDD housing portion 6 a. Yes. Then, the HDD 5 is installed on the second vibration isolation member 20 such that a screw hole (not shown) on the bottom surface of the HDD 5 is positioned on the hollow portion of the second vibration isolation member 20. Then, the HDD 5 is coupled to the HDD bracket 18 by screwing a screw from below the boss 6 h of the case member 6.

好ましくは、第１防振部材１９は第２防振部材２０よりも柔らかい（弾性変形しやすい、弾性率が小さい）材料によって形成されている。ＨＤＤ５の長辺方向で見ると、第１防振部材１９は、第２防振部材２０よりもＨＤＤ５の中心（すなわち内部に存在する磁気ディスクの回転中心であって、ＨＤＤ５の振動中心）から遠い位置に配されている。すなわち、ＨＤＤ５の振動中心から第１防振部材１９までの距離は、ＨＤＤ５の振動中心から第２防振部材までの距離よりも大きくなっている。詳細には、ＨＤＤブラケット１８の短辺が第１防振部材１９を介してケース部材６に取り付けられ、ＨＤＤブラケット１８の長辺に第２防振部材２０を介してＨＤＤ５が取り付けられている。従って、振動中心から遠くなるほど振動の周波数が低くなる（振幅が大きくなる）ので、第１防振部材１９にはＨＤＤ５の振動のうち、特に低周波成分（振幅が大きい振動）が伝達されるが、第１防振部材１９に弾性変形しやすい柔らかい材料を用いることで、低周波数の振動を良好に減衰できる。弾性変形しやすいことにより、低周波数の振幅の大きい振動に応答して第１防振部材１９が十分に変形することができるからである。一方、第２防振部材２０にはＨＤＤ５の振動のうち、特に高周波成分（振幅が小さい振動）が伝達されるが、第２防振部材２０に弾性変形しにくい固い材料を用いることで、高周波数の振動を良好に減衰できる。弾性変形しにくいが、高周波数の振幅の小さい振動に応答して第２防振部材２０が十分に変形することができるからである。   Preferably, the first vibration isolation member 19 is made of a material softer (easily elastically deformed and has a lower elastic modulus) than the second vibration isolation member 20. When viewed in the long side direction of the HDD 5, the first vibration isolation member 19 is farther from the center of the HDD 5 than the second vibration isolation member 20 (that is, the center of rotation of the magnetic disk existing inside and the vibration center of the HDD 5). Arranged in position. That is, the distance from the vibration center of the HDD 5 to the first vibration isolation member 19 is larger than the distance from the vibration center of the HDD 5 to the second vibration isolation member. Specifically, the short side of the HDD bracket 18 is attached to the case member 6 via the first vibration isolation member 19, and the HDD 5 is attached to the long side of the HDD bracket 18 via the second vibration isolation member 20. Accordingly, since the frequency of vibration decreases (the amplitude increases) as the distance from the vibration center increases, a low frequency component (vibration with a large amplitude) among the vibrations of the HDD 5 is transmitted to the first vibration isolation member 19. By using a soft material that is easily elastically deformed for the first vibration isolation member 19, it is possible to satisfactorily attenuate low-frequency vibrations. This is because the first vibration isolation member 19 can be sufficiently deformed in response to vibration with a low frequency and large amplitude due to being easily elastically deformed. On the other hand, a high frequency component (vibration with a small amplitude) of the vibration of the HDD 5 is transmitted to the second vibration isolation member 20, but the second vibration isolation member 20 is made of a hard material that is not easily elastically deformed. The vibration of the frequency can be damped well. This is because the second vibration isolating member 20 can be sufficiently deformed in response to vibration with high frequency and small amplitude, although it is difficult to elastically deform.

また、第１防振部材１９は第２防振部材２０よりも厚みが厚く（厚みが厚いと弾性変形しやすい）形成されている。ＨＤＤ５の長辺方向で見ると、第１防振部材１９は、第２防振部材２０よりもＨＤＤ５の中心から遠い位置に配されている。従って、第１防振部材１９にはＨＤＤ５の振動のうち、特に低周波成分（振幅が大きい振動）が伝達されるが、第１防振部材１９に弾性変形しやすい厚いものを用いることで、振動を良好に減衰できる。一方、第２防振部材２０にはＨＤＤ５の振動のうち、特に高周波成分（振幅が小さい振動）が伝達されるが、第２防振部材２０に弾性変形しにくい薄いものを用いることで、振動を良好に減衰できる。   The first vibration isolation member 19 is formed to be thicker than the second vibration isolation member 20 (easily elastically deformed when the thickness is large). When viewed in the long side direction of the HDD 5, the first vibration isolation member 19 is disposed at a position farther from the center of the HDD 5 than the second vibration isolation member 20. Therefore, although the low frequency component (vibration with a large amplitude) of the vibration of the HDD 5 is transmitted to the first vibration isolation member 19, the first vibration isolation member 19 is thick and easily elastically deformed. Vibration can be damped well. On the other hand, a high frequency component (a vibration having a small amplitude) of the vibration of the HDD 5 is transmitted to the second vibration isolation member 20, but the second vibration isolation member 20 is vibrated by using a thin one that is not easily elastically deformed. Can be attenuated satisfactorily.

ＨＤＤ５が第２防振部材２０を介してＨＤＤブラケット１８に結合されるので、ＨＤＤ５で発生する振動はＨＤＤブラケット１８に伝達される際にその大半が第２防振部材２０によって吸収され減衰される。従って、ＨＤＤブラケット１８がＨＤＤ５から伝達される振動によって振動し、雑音を発生することを抑制できる。さらに、ＨＤＤブラケット１８が第１防振部材１９を介してケース部材６に結合されるので、ＨＤＤブラケット１８からケース部材６に伝達される振動の大半は、第１防振部材によって吸収され減衰される。従って、ケース部材６がＨＤＤブラケット１８から伝達される振動によって振動し、雑音を発生することを抑制できる。また、ＨＤＤブラケット１８が第１防振部材１９を介してケース部材６に結合されるので、ＨＤＤブラケット１８は、ＨＤＤ収納部６ａの底面から若干持ち上げられた（底面から所定の間隔が空けられた）状態で取り付けられる。なお、第１防振部材１９および第２防振部材２０が円筒形状（リング形状）に形成されているので、各第１防振部材１９および第２防振部材２０の全周に亘って略均一に振動を吸収することができる。   Since the HDD 5 is coupled to the HDD bracket 18 via the second vibration isolation member 20, most of the vibration generated in the HDD 5 is absorbed and attenuated by the second vibration isolation member 20 when transmitted to the HDD bracket 18. . Therefore, it can be suppressed that the HDD bracket 18 is vibrated by the vibration transmitted from the HDD 5 to generate noise. Further, since the HDD bracket 18 is coupled to the case member 6 via the first vibration isolation member 19, most of the vibration transmitted from the HDD bracket 18 to the case member 6 is absorbed and attenuated by the first vibration isolation member. The Therefore, it is possible to suppress the case member 6 from vibrating due to the vibration transmitted from the HDD bracket 18 and generating noise. Further, since the HDD bracket 18 is coupled to the case member 6 via the first vibration isolation member 19, the HDD bracket 18 is slightly lifted from the bottom surface of the HDD housing portion 6a (a predetermined interval is spaced from the bottom surface). ) Installed in the state. In addition, since the first vibration isolation member 19 and the second vibration isolation member 20 are formed in a cylindrical shape (ring shape), the entire circumference of each of the first vibration isolation member 19 and the second vibration isolation member 20 is substantially omitted. Vibrations can be absorbed uniformly.

好ましくは、図１２のように、ＨＤＤブラケット１８の底板部１８ａには、１又は複数の開口１８ｃが形成されている。開口１８ｃの形状は、任意の適切な形状が採用され得るが、本例の場合、８つの円形の開口１８ｃが形成されている。円形以外では、長円径や楕円形など頂点を有しない形状が採用される。開口１８ｃが形成されることによって、ＨＤＤブラケット１８の下側を流れる空気は、開口１８ｃを介してＨＤＤ１８の上側に流入するので、ＨＤＤ５の放熱効果を高くすることができる。すなわち、ＨＤＤ５近傍の暖められた空気と、ＨＤＤブラケット１８下側の比較的冷たい空気とが開口１８ｃを介して相互に流入し合うことによって、ＨＤＤ５に冷たい空気を供給することができる。なお、開口１８ｃを形成する代わりに、ＨＤＤブラケット１８を左右２つに分割した形状にし、ＨＤＤブラケット１８上下で空気が移動できるようにしてもよい。   Preferably, as shown in FIG. 12, one or more openings 18 c are formed in the bottom plate portion 18 a of the HDD bracket 18. Any appropriate shape can be adopted as the shape of the opening 18c. In this example, eight circular openings 18c are formed. Other than the circular shape, a shape having no vertex such as an ellipse or an ellipse is adopted. By forming the opening 18c, the air flowing under the HDD bracket 18 flows into the upper side of the HDD 18 through the opening 18c, so that the heat dissipation effect of the HDD 5 can be enhanced. That is, the warm air in the vicinity of the HDD 5 and the relatively cool air below the HDD bracket 18 flow into each other through the opening 18c, so that cold air can be supplied to the HDD 5. Instead of forming the opening 18c, the HDD bracket 18 may be divided into two parts on the left and right sides so that the air can move above and below the HDD bracket 18.

また、開口１８ｃが形成されることによって、同一の厚みを有するＨＤＤブラケット１８を採用した場合に、ＨＤＤブラケット１８の重量を小さくすることができる。第１防振部材１９および第２防振部材２０には、ＨＤＤ５を支持すると共にＨＤＤ５の振動を正常に吸収するために、ＨＤＤ５とＨＤＤブラケット１８の総重量には制限が設けられている。ＨＤＤ５の重量を変更できない場合、ＨＤＤブラケット１８の重量を小さくする必要があるが、ＨＤＤブラケット１８を薄くして重量を小さくすると、ＨＤＤブラケット１８の強度が弱くなりＨＤＤブラケット１８から騒音が発生する可能性がある。しかし、本例では、開口１８ｃを形成することによってＨＤＤブラケット１８の重量を小さくしているので、このような問題が発生しない。また、開口１８ｃが円形であることにより例えば四角形の場合に比べてＨＤＤブラケット１８の強度を高くできる。   Further, by forming the opening 18c, when the HDD bracket 18 having the same thickness is employed, the weight of the HDD bracket 18 can be reduced. The first vibration isolation member 19 and the second vibration isolation member 20 are limited in the total weight of the HDD 5 and the HDD bracket 18 in order to support the HDD 5 and normally absorb vibrations of the HDD 5. When the weight of the HDD 5 cannot be changed, it is necessary to reduce the weight of the HDD bracket 18. However, if the HDD bracket 18 is thinned to reduce the weight, the strength of the HDD bracket 18 becomes weak and noise may be generated from the HDD bracket 18. There is sex. However, in this example, since the weight of the HDD bracket 18 is reduced by forming the opening 18c, such a problem does not occur. Further, since the opening 18c is circular, the strength of the HDD bracket 18 can be increased as compared with, for example, a rectangular shape.

ファン８は、図８のように、ファン収納部６ｂに収納された後、図示しない防振部材を取り付けて、ネジによってファン収納部６ｂに結合される。ファン８によって発生する振動も、上記同様に、第２防振部材２０、第１防振部材１９によって吸収され減衰される。   As shown in FIG. 8, the fan 8 is housed in the fan housing portion 6b, and then attached with an anti-vibration member (not shown) and coupled to the fan housing portion 6b by screws. Similarly to the above, the vibration generated by the fan 8 is absorbed and attenuated by the second vibration isolation member 20 and the first vibration isolation member 19.

カバー部材７は、ケース部材６にＨＤＤ５およびファン８が結合された後、ケース部材６の上面開口を覆うと共に、ケース部材６と共に筐体１の側面シャーシ１５にネジによって結合されるものである。カバー部材７は、ケース部材６の上面開口よりもやや大きい、略矩形上の薄い板状である。カバー部材７によって、ケース部材６の上面開口を完全に塞がれるので、ＨＤＤ５収納部６ａ内を流れる空気がケース部材６の上面方向に漏れることを防止できる。また、カバー部材７によって、ＨＤＤ５から発生する駆動音等の騒音が筐体１外部に漏れることを抑制することができる。   The cover member 7 covers the upper surface opening of the case member 6 after the HDD 5 and the fan 8 are coupled to the case member 6 and is coupled to the side chassis 15 of the housing 1 together with the case member 6 by screws. The cover member 7 has a substantially rectangular thin plate shape that is slightly larger than the upper surface opening of the case member 6. Since the upper surface opening of the case member 6 is completely closed by the cover member 7, it is possible to prevent the air flowing in the HDD 5 storage portion 6 a from leaking in the upper surface direction of the case member 6. Further, the cover member 7 can suppress noise such as driving sound generated from the HDD 5 from leaking outside the housing 1.

ケース部材６に形成されたネジ挿入孔６ｉ（図７、図８、図１３参照）が側面シャーシ１５に形成されたネジ孔１５ａ（図７、図１３参照）の位置に対応するように、ケース部材６は、筐体１内に収納され、側面シャーシ１５および前面シャーシ２４上に設置される。なお、図１３に示すように、ケース部材６のネジ挿入孔６ｉの周囲には位置決めリブ６ｊが形成されているので、ネジ挿入孔６ｉとネジ孔１５ａとを容易に位置決めすることができる。その後、カバー部材７に形成されたネジ挿入孔７ａ（図５参照）が側面シャーシ１５に形成されたネジ孔１５ａの位置に対応するように、カバー部材７をケース部材６の上部に配置し、ネジ止めすることによって、カバー部材７およびケース部材６が、側面シャーシ１５に結合される。   The case so that the screw insertion hole 6i (see FIGS. 7, 8, and 13) formed in the case member 6 corresponds to the position of the screw hole 15a (see FIGS. 7 and 13) formed in the side chassis 15. The member 6 is housed in the housing 1 and installed on the side chassis 15 and the front chassis 24. As shown in FIG. 13, since the positioning rib 6j is formed around the screw insertion hole 6i of the case member 6, the screw insertion hole 6i and the screw hole 15a can be easily positioned. After that, the cover member 7 is arranged on the upper portion of the case member 6 so that the screw insertion hole 7a (see FIG. 5) formed in the cover member 7 corresponds to the position of the screw hole 15a formed in the side chassis 15. The cover member 7 and the case member 6 are coupled to the side chassis 15 by screwing.

以上の構成を有するパソコン１００の放熱構造の作用について、図３を参照して、説明する。   The operation of the heat dissipation structure of the personal computer 100 having the above configuration will be described with reference to FIG.

ファン８が駆動されると、ファン８の吸引力によって、ケース部材６のＨＤＤ収納部６ａ内部のＨＤＤ５によって暖められた空気は、矢印Ａに示すように、ＨＤＤ収納部６ａ内を後方に移動し、ファン収納部６ｂおよび開口６ｆを介してケース部材６の外部に放出される。そして、矢印Ａに示すように、下部シャーシ１２の吸入口１６から筐体１外部の冷たい空気が筐体１内部に吸入されて、その冷たい空気が開口６ｄを介してＨＤＤ収納部６ａ内に取り込まれる。このように、ＨＤＤ収納部６ａ内では、ＨＤＤ５によって暖められた空気がケース部材６の外部に放出され、外部から吸入された冷たい空気が取り込まれることにより、ＨＤＤ収納部６ａに収納されたＨＤＤ５を放熱することができる。   When the fan 8 is driven, the air warmed by the HDD 5 inside the HDD housing portion 6a of the case member 6 moves backward in the HDD housing portion 6a as indicated by an arrow A by the suction force of the fan 8. Then, it is discharged to the outside of the case member 6 through the fan housing portion 6b and the opening 6f. As indicated by an arrow A, cold air outside the housing 1 is sucked into the housing 1 from the suction port 16 of the lower chassis 12, and the cold air is taken into the HDD housing 6a through the opening 6d. It is. As described above, in the HDD storage portion 6a, the air warmed by the HDD 5 is discharged to the outside of the case member 6, and the cold air sucked from the outside is taken in, whereby the HDD 5 stored in the HDD storage portion 6a is stored. It can dissipate heat.

また、ファン８が駆動されると、ファン８の吸引力によって、吸入口１６と開口１６ｅとを結ぶ略直線上の領域（流路Ｂ上）に配されているアンプ部２や電源トランス３周囲の暖められた空気は、矢印Ｂに示すように、開口６ｅを介して筒状部６ｃ内に取り込まれ、ファン収納部６ｂおよび開口６ｆを介してケース部材６の外部に放出される。そして、矢印Ｂに示すように、下部シャーシ１２の吸入口１６から筐体１外部の冷たい空気が筐体１内部に吸入されて、その冷たい空気がアンプ部２や電源トランス３の周囲に取り込まれる。このように、ケース部材６の下側では、アンプ部２および電源トランス３によって暖められた空気がケース部材６の筒状部６ｃを通ってケース部材６の後方に放出され、外部から吸入された冷たい空気が取り込まれることにより、ケース部材６の下方に配置されたアンプ部２や電源トランス３を放熱することができる。   Further, when the fan 8 is driven, the surroundings of the amplifier unit 2 and the power transformer 3 arranged in a substantially straight region (on the flow path B) connecting the suction port 16 and the opening 16e by the suction force of the fan 8 As shown by the arrow B, the warmed air is taken into the cylindrical portion 6c through the opening 6e and discharged to the outside of the case member 6 through the fan housing portion 6b and the opening 6f. Then, as shown by an arrow B, cold air outside the housing 1 is sucked into the housing 1 from the suction port 16 of the lower chassis 12, and the cold air is taken around the amplifier unit 2 and the power transformer 3. . As described above, on the lower side of the case member 6, the air heated by the amplifier unit 2 and the power transformer 3 is discharged to the rear of the case member 6 through the cylindrical portion 6c of the case member 6, and is sucked from the outside. By taking in cold air, it is possible to dissipate heat from the amplifier unit 2 and the power transformer 3 disposed below the case member 6.

また、排気用ファン９が駆動されることによって、ファン８によってケース部材６の後面から放出された暖かい空気は、排気用ファン９の吸引力によって、ダクト部材１０内に吸入される。ダクト部材１０の後部開口には後面パネル１３の排気口１７が位置しているので、ダクト部材１０に取り込まれた暖かい空気はダクト部材１０内を移動し、排気口１７を介して筐体１の外部に放出される。   Further, when the exhaust fan 9 is driven, warm air released from the rear surface of the case member 6 by the fan 8 is sucked into the duct member 10 by the suction force of the exhaust fan 9. Since the exhaust port 17 of the rear panel 13 is located at the rear opening of the duct member 10, the warm air taken into the duct member 10 moves through the duct member 10 and is connected to the housing 1 via the exhaust port 17. Released to the outside.

このように１つのファン８のみによって、筐体１の上方に配されるＨＤＤ５と、筐体１の下方に配されるアンプ部２、電源トランス３とを効果的に放熱することができる。したがって、従来のパソコンと比べ、ファンの数を削減することができ、コストの低減化を図ることができる。また、パソコンの静音化に寄与することができる。   Thus, only one fan 8 can effectively radiate heat from the HDD 5 disposed above the housing 1, the amplifier unit 2, and the power transformer 3 disposed below the housing 1. Therefore, the number of fans can be reduced and costs can be reduced as compared with a conventional personal computer. Moreover, it can contribute to noise reduction of a personal computer.

また、上記のようなケース部材６の構造によって、吸入口１６から吸入された空気がＨＤＤ収納部６ａを移動してケース部材６の後方に放出される流路Ａと、吸入口１６から吸入された空気がアンプ部２や電源トランス３の位置を介してケース部材６の後方に放出される流路Ｂとが分離されている（すなわち、流路Ａ上にはアンプ部２や電源トランス３が配されず、流路Ｂ上にはＨＤＤ５が配されない）ので、１つのファン８のみでＨＤＤ５、アンプ部２、電源トランス３を放熱しているにも関わらず、アンプ部２や電源トランス３で熱せられた空気がＨＤＤ５に移動して、ＨＤＤ５の放熱を妨げることを防止でき、逆にＨＤＤ５で熱せられた空気がアンプ部２や電源トランス３に移動して、アンプ部２や電源トランス３の放熱を妨げることを防止できる。   Further, due to the structure of the case member 6 as described above, the air sucked from the suction port 16 moves through the HDD housing portion 6 a and is discharged to the rear of the case member 6, and is sucked from the suction port 16. The flow path B through which the air is discharged to the rear of the case member 6 through the position of the amplifier section 2 and the power transformer 3 is separated (that is, the amplifier section 2 and the power transformer 3 are disposed on the flow path A. The HDD 5 is not arranged on the flow path B), so that the amplifier 5, the power transformer 3, and the power transformer 3 are radiated by only one fan 8 even though the HDD 5, the amplifier 2, and the power transformer 3 are dissipated. It is possible to prevent the heated air from moving to the HDD 5 and hindering the heat dissipation of the HDD 5, and conversely, the air heated by the HDD 5 moves to the amplifier unit 2 and the power transformer 3. Hinder heat dissipation It can be prevented.

次に、パソコン１００における、ＨＤＤ５の交換方法について説明する。
まず、図示しない天板を筐体１から取り外した後、図５に示すように、カバー部材７に螺合されているネジを取り外し、カバー部材７とケース部材６と側面シャーシ１５との結合を解除する。次に、図６に示すように、カバー部材７をケース部材６の上面から取り外す。次に、図７に示すように、（ファン８の図示しないケーブルを取り外した後）ケース部材６を持ち上げて、ケース部材６を筐体１内部から取り出す。続いて、ケース部材６の底面から第２防振部材２０を介してＨＤＤ５に螺合されているネジを取り外すことによって、ＨＤＤ５とＨＤＤブラケット１８との結合を解除する。ＨＤＤ５をケース部材６の中から取りだして、別のＨＤＤ５をケース部材６の中に収納し、ケース部材６の底面から第２防振部材２０を介してＨＤＤ５に螺合することによって、ＨＤＤブラケット１８にＨＤＤ５を結合する。以降は、カバー部材７やケース部材６を側面シャーシ１５から取り外した時とは逆の手順で、ケース部材６およびカバー部材７を側面シャーシ１５に結合することによって、ＨＤＤ５の交換が終了する。 Next, a method for replacing the HDD 5 in the personal computer 100 will be described.
First, after removing a top plate (not shown) from the housing 1, as shown in FIG. 5, a screw screwed to the cover member 7 is removed, and the cover member 7, the case member 6, and the side chassis 15 are joined. To release. Next, as shown in FIG. 6, the cover member 7 is removed from the upper surface of the case member 6. Next, as shown in FIG. 7, the case member 6 is lifted (after the cable (not shown) of the fan 8 is removed), and the case member 6 is taken out of the housing 1. Subsequently, the screw between the HDD 5 and the HDD bracket 18 is released by removing a screw screwed into the HDD 5 from the bottom surface of the case member 6 via the second vibration isolation member 20. The HDD 5 is taken out from the case member 6, and another HDD 5 is accommodated in the case member 6, and is screwed into the HDD 5 from the bottom surface of the case member 6 via the second vibration isolation member 20. HDD 5 is coupled to the. Thereafter, the replacement of the HDD 5 is completed by coupling the case member 6 and the cover member 7 to the side chassis 15 in the reverse procedure to the case where the cover member 7 and the case member 6 are removed from the side chassis 15.

以上のように、パソコン１００においては、ＨＤＤ５がケース部材６内に着脱可能に結合されて、ケース部材６が筐体１に着脱可能に結合されているので、ケース部材６を筐体１から取り出すことによって、きわめて容易にＨＤＤ５を交換することができる。ケース部材６が筐体１の上方に配置されていることによって、ＨＤＤ５の交換がされに容易になる。   As described above, in the personal computer 100, the HDD 5 is detachably coupled to the case member 6, and the case member 6 is detachably coupled to the housing 1, so that the case member 6 is removed from the housing 1. Thus, the HDD 5 can be replaced very easily. Since the case member 6 is disposed above the housing 1, the HDD 5 can be easily replaced.

以上、本発明の好ましい実施形態を説明したが、本発明はこれらの実施形態には限定されない。例えば、ケース部材６、アンプ部２、電源トランス３等を設置する位置は、上記の実施形態に限定されない。ケース部材６の後面（つまり、ファン８）を後面パネル１３の排気口１７の近傍に設置する場合には、排気用ファン９やダクト部材１０は不要である。カバー部材７を設ける代わりに、天板や側面シャーシなどでケース部材６の上面開口を覆うようにしてもよい。ケース部材６に形成される各開口や、吸入口１６の位置も上記の実施形態には限定されない。例えば、開口６ｄ、６ｅはファン８に対向していなくてもよく、下向きに形成されていてもよい。また、ケース部材６にＨＤＤ５以外の他の発熱部材（アンプ部２、ＣＰＵ、ＤＶＤドライブ等）が収納されてもよく、流路Ｂ上にアンプ部２や電源トランス３以外の発熱部材（ＨＤＤ５、ＣＰＵ、ＤＶＤドライブ等）が配置されてもよい。また、本発明は、ＨＤＤレコーダ等のパソコン以外の電子機器に適用されてもよい。   As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these embodiment. For example, the positions where the case member 6, the amplifier unit 2, the power transformer 3, etc. are installed are not limited to the above embodiment. When the rear surface of the case member 6 (that is, the fan 8) is installed in the vicinity of the exhaust port 17 of the rear panel 13, the exhaust fan 9 and the duct member 10 are unnecessary. Instead of providing the cover member 7, the upper surface opening of the case member 6 may be covered with a top plate, a side chassis or the like. Each opening formed in the case member 6 and the position of the suction port 16 are not limited to the above embodiment. For example, the openings 6d and 6e do not have to face the fan 8 and may be formed downward. The case member 6 may contain other heat generating members (amplifier unit 2, CPU, DVD drive, etc.) other than the HDD 5, and the heat generating members other than the amplifier unit 2 and the power transformer 3 (HDD 5, CPU, DVD drive, etc.) may be arranged. The present invention may also be applied to electronic devices other than personal computers such as HDD recorders.
