Description

本発明は電子部品冷却装置に関するものであり、特に、コンピュータ等の電子部品の水冷方式に適用して好適な電子部品冷却装置に関するものである。   The present invention relates to an electronic component cooling apparatus, and more particularly to an electronic component cooling apparatus suitable for application to a water cooling system for electronic components such as computers.

従来、電子機器の部品、例えばパソコンのＣＰＵに用いられる水冷方式を採用した冷却装置においては、冷却液タンクの冷却液をラジエータ側に圧送するため、冷却液タンクの内部又は外部に圧送ポンプが設けたものがある。図４は、此種の電子部品冷却装置１の一例を示す全体構成図である。   Conventionally, in a cooling device adopting a water cooling method used for electronic parts, for example, a CPU of a personal computer, a pump is provided inside or outside the coolant tank to pump the coolant in the coolant tank to the radiator side. There is something. FIG. 4 is an overall configuration diagram showing an example of this type of electronic component cooling apparatus 1.

図４において、２は空冷ファン３を備えたラジエータであり、４は圧送ポンプ５を備えた冷却液タンクである。該冷却液タンク４とラジエータ２とは流体流路６により接続されている。又、７は熱源たるＣＰＵ（電子部品）を冷却するための電子部品用ヒートシンクである。ヒートシンク７とラジエータ２は流体流路８により接続され、且つ、ヒートシンク７と冷却液タンク４は流体流路９により接続されている。   In FIG. 4, 2 is a radiator provided with an air cooling fan 3, and 4 is a coolant tank provided with a pressure feed pump 5. The coolant tank 4 and the radiator 2 are connected by a fluid flow path 6. Reference numeral 7 denotes a heat sink for electronic components for cooling a CPU (electronic component) as a heat source. The heat sink 7 and the radiator 2 are connected by a fluid flow path 8, and the heat sink 7 and the coolant tank 4 are connected by a fluid flow path 9.

前記の構成において、冷却液タンク４内の冷却液Ｃは、圧送ポンプ５によりラジエータ２を経てヒートシンク７に供給された後に、冷却液タンク４に戻されて、再び前記同様に冷却液Ｃが循環供給される。この電子部品冷却装置１では、空冷ファン３と圧送ポンプ５は、それぞれ別々の駆動モータにより駆動されている（例えば、特許文献１）。
特開２００４−３０４０７６号公報 In the above-described configuration, the coolant C in the coolant tank 4 is supplied to the heat sink 7 via the radiator 2 by the pressure feed pump 5 and then returned to the coolant tank 4 so that the coolant C circulates again in the same manner as described above.

JP 2004-304076 A

従来の上記冷却装置１は、冷却液用圧送ポンプ５を駆動する駆動モータと、空冷ファン３を駆動する駆動モータとが互いに独立別個に設けられているので、電子部品冷却装置全体として、圧送ポンプ５及び空冷ファン３に対する駆動効率が悪いという問題がある。また、駆動モータはポンプ用とファン用の２台を必要とするため、２台の駆動モータを設置するための場所（スペース）が広くなって、小型化が図れないと共にコスト高を招き、加えて、各々の駆動モータから発生する騒音も大きくなる。   Since the conventional cooling device 1 is provided with a drive motor for driving the coolant pump 5 and a drive motor for driving the air cooling fan 3 separately and independently from each other, the entire electronic component cooling device has a pressure pump. 5 and the air cooling fan 3 have a problem of poor driving efficiency. Moreover, since the drive motor requires two units for the pump and the fan, the space (space) for installing the two drive motors is widened, so that the size cannot be reduced and the cost is increased. Thus, the noise generated from each drive motor also increases.

そこで、駆動モータによる圧送ポンプ及び空冷ファンの駆動効率を向上させると共に騒音を抑制し、且つ、電子部品冷却装置の小型化を図るために解決すべき技術的課題が生じてくるのであり、本発明は該課題を解決することを目的とする。   Therefore, there is a technical problem to be solved in order to improve the driving efficiency of the pumping pump and the air cooling fan by the drive motor, to suppress noise, and to reduce the size of the electronic component cooling device.

There is no need to provide a gear between the shaft.

請求項３記載の発明は、上記圧送ポンプは、冷却液タンク内に回転自在に収容されたマグネットロータ部と、上記駆動モータの出力軸の端部に固設したロータ駆動部とを有し、該ロータ駆動部の回転によって前記マグネットロータ部が磁気的に回転駆動される請求項１又は２記載の電子部品冷却装置を提供する。   The invention according to claim 3 is characterized in that the pressure pump has a magnet rotor part rotatably accommodated in a coolant tank, and a rotor drive part fixed to the end of the output shaft of the drive motor, The electronic component cooling device according to claim 1 or 2, wherein the magnet rotor part is magnetically driven to rotate by the rotation of the rotor driving part.

この構成によれば、前記圧送ポンプの羽根部材を駆動モータの出力軸に直結したので、羽根部材が出力軸と一体に回転することにより、冷却液タンク内の冷却液がラジエータ側に圧送される。   According to this configuration, since the blade member of the pressure pump is directly connected to the output shaft of the drive motor, the blade member rotates integrally with the output shaft, so that the coolant in the coolant tank is pumped to the radiator side. .

請求項１記載の発明は、前記空冷ファン及び圧送ポンプを駆動するために、従来２台の駆動モータが必要であったのが、１台の駆動モータで済むので、従来に較べて該モータ動力の駆動伝達効率が大幅に向上すると共に、駆動モータの設置スペースを半減でき、空冷ファンと圧送ポンプの駆動部の小型化を実現することができる。さらに、本発明は、駆動モータ１台分のコストダウンが図れるばかりでなく、駆動モータから発生する騒音を半分に抑制することができる。   According to the first aspect of the present invention, two drive motors are conventionally required to drive the air-cooling fan and the pressure feed pump, but only one drive motor is required.

請求項３記載の発明は、冷却液タンク内に圧送ポンプのマグネットロータ部が収容され、且つ、該マグネットロータ部は回転軸受け部を有しないので、請求項１又は２記載の効果に加えて、一層の小型化が図られるだけでなく、軸受け用シール部材が不要になり、且つ、液漏れの心配がないという優れた効果を奏する。又、マグネットロータ部は回転時に軸摺動抵抗を受けないので、より円滑な回転を確保できるのみならず、回転駆動時に生じる騒音を一層効果的に抑制することができる。   In the invention according to claim 3, since the magnet rotor part of the pressure feed pump is accommodated in the coolant tank, and the magnet rotor part does not have the rotating bearing part, in addition to the effect according to claim 1 or 2, In addition to the further miniaturization, the bearing sealing member is unnecessary, and there is an excellent effect that there is no fear of liquid leakage.

請求項４記載の発明は、冷却液タンク内に圧送ポンプの羽根部材が収容され、且つ、該羽根部材が駆動モータの出力軸により直接駆動されるので、請求項１又は２記載の効果に加えて、一層の小型化が図られるだけでなく、構造が簡単で製作が容易であるうえに、駆動モータから圧送ポンプへの回転駆動力の伝達効率を更に高めることができる。   In the invention described in claim 4, since the blade member of the pressure feed pump is accommodated in the coolant tank, and the blade member is directly driven by the output shaft of the drive motor, the effect of claim 1 or 2 is added.

以下、本発明の一実施の形態を図１乃至図３に従って説明する。本実施例は、空冷ファン１５を備えたラジエータ２５と、電子部品用ヒートシンク１２と、冷却液強制循環用圧送ポンプ１８を備えた冷却液タンク１４とを循環経路１３，２４により冷却液再循環可能に接続した強制水冷方式のＣＰＵクーラー装置において、空冷ファン１５の駆動モータ２０の動力を使って、圧送ポンプ１８をも同時に回転駆動させるようにしたものである。なお、本実施例では、圧送ポンプ１８と冷却液タンク１４は、装置の更なる小型化を実現するために、一体構造に形成しているが、別体構造に形成することも勿論可能である。   Hereinafter, an embodiment of the present invention will be described with reference to FIGS. In this embodiment, a coolant 25 including an air cooling fan 15, a heat sink 12 for electronic components, and a coolant tank 14 provided with a pressure feed pump 18 for forced circulation of coolant can be recirculated with coolant through circulation paths 13 and 24. In the forced water cooling type CPU cooler device connected to, the pump pump 18 is also rotated at the same time using the power of the drive motor 20 of the air cooling fan 15. In the present embodiment, the pumping pump 18 and the coolant tank 14 are formed in an integral structure in order to realize further downsizing of the apparatus, but can of course be formed in a separate structure. .

図１は、一実施の形態に係る電子部品冷却装置１１の全体構成図である。電子部品冷却装置１１は、電子部品用金属製ヒートシンク１２として機能するＣＰＵ用水冷ヘッドを具備している。該ヒートシンク１２は、発熱源となるＣＰＵに接触して、ＣＰＵの発生熱を冷却液（冷却水又はグリコール系の不凍液）Ｃに移して放出させる。又、ヒートシンク１２の流入口には、流体流路１３を介して冷却液（リザーブ）タンク１４が接続され、冷却液タンク１４には冷却液Ｃが蓄えられている。   FIG. 1 is an overall configuration diagram of an electronic component cooling device 11 according to an embodiment. The electronic component cooling device 11 includes a CPU water-cooling head that functions as a metal heat sink 12 for electronic components. The heat sink 12 is in contact with the CPU serving as a heat generation source, and transfers the heat generated by the CPU to the cooling liquid (cooling water or glycol-based antifreezing liquid) C for release. A coolant tank 14 is connected to the inlet of the heat sink 12 via a fluid flow path 13, and the coolant C is stored in the coolant tank 14.

図２に示すように、冷却液タンク１４の一側壁、他側壁にはそれぞれ流入口１６、流出口１７が形成されている。更に、冷却液タンク１４には、冷却液Ｃをヒートシンク１２側に強制循環させるための回転式圧送ポンプ１８が具備されている。この圧送ポンプ１８は、円板型のマグネットロータ部１９と円板型のロータ駆動部２２とにより構成され、該ロータ駆動部２２は、駆動モータ２０の出力軸２１の一端部に固設されている。又、前記マグネットロータ部１９は、冷却液タンク１４内に回転自在に収容されている。   As shown in FIG. 2, an inlet 16 and an outlet 17 are formed on one side wall and the other side wall of the coolant tank 14, respectively. Further, the coolant tank 14 is provided with a rotary pressure feed pump 18 for forcibly circulating the coolant C to the heat sink 12 side. The pumping pump 18 includes a disc-shaped magnet rotor portion 19 and a disc-shaped rotor driving portion 22, and the rotor driving portion 22 is fixed to one end portion of the output shaft 21 of the driving motor 20. Yes. The magnet rotor portion 19 is rotatably accommodated in the coolant tank 14.

また、マグネットロータ部１９の表面には、複数枚の羽根２３が一体に形成され、該羽根２３は流入口１６側に突出している。更に、マグネットロータ部１９及びロータ駆動部２２は、冷却液タンク１４の壁面を介して、互いに同芯上にて対向して近接配置され、これら各対向面の周縁部には、複数のＮ極とＳ極が円周方向に交互に着磁されている。   A plurality of blades 23 are integrally formed on the surface of the magnet rotor portion 19, and the blades 23 protrude toward the inlet 16. Further, the magnet rotor unit 19 and the rotor driving unit 22 are arranged close to each other on the same core via the wall surface of the coolant tank 14, and a plurality of N poles are provided at the peripheral portions of these opposing surfaces. And S poles are alternately magnetized in the circumferential direction.

従って、ロータ駆動部２２の回転によって、マグネットロータ部１９が磁気的に回転駆動され、流入口１６から冷却液タンク１４内に冷却液Ｃが流入すると同時に、流出口１７から冷却液Ｃが流出する。流出した冷却液Ｃは、流体流路１３を通ってヒートシンク１２側に供給される。   Accordingly, the rotation of the rotor drive unit 22 causes the magnet rotor unit 19 to be rotationally driven magnetically, so that the coolant C flows into the coolant tank 14 from the inlet 16 and at the same time the coolant C flows out from the outlet 17. . The coolant C that has flowed out is supplied to the heat sink 12 through the fluid flow path 13.

前記ヒートシンク１２の流出口は、流体流路２４を介して、ラジエータ２５の流入口２６に接続されている。これにより、ＣＰＵを冷却した後の冷却液Ｃは、流体流路２４を通ってラジエータ２５に供給される。このラジエータ２５は、冷却液Ｃから熱を奪って空気中に排出する。   An outlet of the heat sink 12 is connected to an inlet 26 of a radiator 25 through a fluid flow path 24. Thereby, the coolant C after cooling the CPU is supplied to the radiator 25 through the fluid flow path 24. The radiator 25 takes heat from the coolant C and discharges it into the air.

ラジエータ２５と冷却液タンク１４との間には、ポンプ・ファン駆動ユニット２７が配設されている。該ポンプ・ファン駆動ユニット２７は、１台の駆動モータ２０と、該駆動モータ２０の一側（図２における左側）に近接配置された空冷ファン１５と、前記駆動モータ２０の他側（図２における右側）に近接配置されたロータ駆動部２２とから成る。   A pump / fan drive unit 27 is disposed between the radiator 25 and the coolant tank 14. The pump / fan drive unit 27 includes one drive motor 20, an air cooling fan 15 disposed close to one side of the drive motor 20 (left side in FIG. 2), and the other side of the drive motor 20 (FIG. 2). And the rotor drive unit 22 disposed close to the right side.

駆動モータ２０の出力軸２１の一端部には、前述の如くロータ駆動部２２が固設直結されていると共に、出力軸２１の他端部には、空冷ファン１５が固設直結されている。   As described above, the rotor drive unit 22 is fixed and directly connected to one end portion of the output shaft 21 of the drive motor 20, and the air cooling fan 15 is fixed and directly connected to the other end portion of the output shaft 21.

上記構成からなる電子部品冷却装置１１は、駆動モータ２０の出力軸２１を回転させると、空冷ファン１５及びロータ駆動部２２の双方が同期して回転駆動される。そして、空冷ファン１５の回転によりラジエータ２５が空冷され、冷却液Ｃから熱を奪って空気中に排出する。   In the electronic component cooling device 11 having the above configuration, when the output shaft 21 of the drive motor 20 is rotated, both the air cooling fan 15 and the rotor drive unit 22 are rotationally driven in synchronization. Then, the radiator 25 is cooled by the rotation of the air cooling fan 15, takes heat from the coolant C and discharges it into the air.

又、ロータ駆動部２２の回転により、圧送ポンプ１８のマグネットロータ部１９も磁気的に一体回転する。そして、マグネットロータ部１９と共に回転する羽根２３の水流作用により、ラジエータ２５側の冷却液Ｃが流入口１６から冷却液タンク１４内に流入し、同時に、該冷却液タンク１４の流出口１７から冷却液Ｃが流出する。この流出した冷却液Ｃは、流体流路１３を経て、ヒートシンク１２側に強制的に供給される。   Further, due to the rotation of the rotor drive unit 22, the magnet rotor unit 19 of the pressure feed pump 18 is also magnetically rotated integrally. Then, the coolant C on the radiator 25 side flows into the coolant tank 14 from the inlet 16 by the water flow action of the blades 23 rotating together with the magnet rotor portion 19, and at the same time, the coolant C cools from the outlet 17 of the coolant tank 14. Liquid C flows out. The coolant C that has flowed out is forcibly supplied to the heat sink 12 side through the fluid flow path 13.

而して、該ヒートシンク１２は、ＣＰＵの発生熱を冷却液Ｃに移動させて、ＣＰＵの冷却を行う。該冷却後の冷却液Ｃは、流体流路２４及びラジエータ２５を経て、冷却液タンク１４に戻されたあと、前記同様に、圧送ポンプ１８によりヒートシンク１２側に強制循環される。   Thus, the heat sink 12 cools the CPU by transferring the heat generated by the CPU to the coolant C. The cooled cooling liquid C is returned to the cooling liquid tank 14 through the fluid flow path 24 and the radiator 25, and then forcibly circulated to the heat sink 12 side by the pumping pump 18 as described above.

ここで、圧送ポンプ１８のマグネットロータ部１９は、ベアリングレスで磁気的に回転するので、ロータ回転時に軸受け摺動抵抗が生ぜず、液漏れの恐れがなくシール部材を必要としない。   Here, since the magnet rotor portion 19 of the pumping pump 18 is magnetically rotated without bearings, no bearing sliding resistance is generated when the rotor rotates, there is no risk of liquid leakage, and no seal member is required.

又、空冷ファン１５及び圧送ポンプ１８は、単一の駆動モータ２０により直動されるので、１台の駆動モータ２０で空冷ファン１５及び圧送ポンプ１８が駆動され、ラジエータ２５に対する空冷と、冷却液Ｃに対する強制循環とが同時に実施される。   Further, since the air cooling fan 15 and the pressure pump 18 are directly moved by a single drive motor 20, the air cooling fan 15 and the pressure pump 18 are driven by a single drive motor 20, and the air cooling for the radiator 25 and the cooling liquid are performed. The forced circulation for C is performed simultaneously.

従って、モータ動力の駆動伝達効率が向上すると共に、ポンプ・ファン駆動ユニット２７の設置空間が縮小して、その分だけ装置の小型化が可能になる。さらに、従来２台必要であったモータの数が１台で済むので、駆動モータ２０から生ずる騒音が小さくなる。又、空冷ファン１５及び圧送ポンプ１８と出力軸２１との間にギアを設ける必要がないので、構造がシンプルであり部品点数を低減できる。   Therefore, the drive transmission efficiency of the motor power is improved and the installation space of the pump / fan drive unit 27 is reduced, and the apparatus can be downsized accordingly. Furthermore, since the number of motors conventionally required is two, noise generated from the drive motor 20 is reduced. Further, since it is not necessary to provide a gear between the air cooling fan 15 and the pressure feed pump 18 and the output shaft 21, the structure is simple and the number of parts can be reduced.

本実施例に係るポンプは、マグネット回転駆動式のものに限らず、他のタイプのポンプも採用できる。例えば、図３に示すように、冷却液タンク１４内に回転自在に収容された羽根部材２９を有し、この羽根部材２９の軸部が、駆動モータ２０の出力軸２１の一端部に直結されてなる圧送ポンプ２８も採用できる。   The pump according to the present embodiment is not limited to a magnet rotation drive type, and other types of pumps may be employed. For example, as shown in FIG. 3, the blade member 29 is rotatably accommodated in the coolant tank 14, and the shaft portion of the blade member 29 is directly connected to one end portion of the output shaft 21 of the drive motor 20. It is also possible to adopt a pressure feed pump 28 formed as follows.

このように構成しても、圧送ポンプ２８と空冷ファン１５の駆動効率が向上し、電子部品冷却装置の小型化が可能になる。更に、構造がシンプルであるのみならず、モータ駆動の静音性が増大する。なお、図３中の符号３０は、出力軸２１のタンク貫通箇所に装着したシール部材３０である。   Even if comprised in this way, the drive efficiency of the pumping pump 28 and the air cooling fan 15 improves, and the electronic component cooling device can be reduced in size. Furthermore, not only is the structure simple, but the quietness of the motor drive increases. In addition, the code | symbol 30 in FIG. 3 is the sealing member 30 with which the tank penetration part of the output shaft 21 was mounted | worn.

尚、本発明は、本発明の精神を逸脱しない限り種々の改変を為すことができ、そして、本発明が該改変されたものに及ぶことは当然である。   It should be noted that the present invention can be variously modified without departing from the spirit of the present invention, and the present invention naturally extends to the modified ones.
