本発明は、吸入口及び吐出口構造を改良したポンプ、並びにそれを用いた冷却装置及び電気機器とパーソナルコンピュータに関する。   The present invention relates to a pump having an improved inlet and outlet structure, a cooling device using the pump, an electric device, and a personal computer.

従来より、ポンプとしては、吸入口及び吐出口を有するケーシングの内部に形成されたポンプ室内に、流体（例えば液体）を運ぶためのポンプ溝を外周部に有する円盤状のインペラを回転可能に配設し、そのインペラを回転させることによって、前記ポンプ溝により、流体を前記吸入口から前記ポンプ室内に吸入して前記吐出口から吐出させるようにしたものが知られている。

上記従来のポンプを、例えば電気部品等の発熱部材を冷却する冷却装置に用いようとすると、図１１及び図１２に示す構成が考えられる。このものの場合、ポンプ１は、ケーシング２に、吸入口３及び吐出口４を同一方向に指向させて有する。又、その吸入口３及び吐出口４は、接近して配置される。
これに対して、放熱部５は、ケース主体６とケース蓋体７とで構成されるケース８の内部、特にはケース主体６の内部の上部に放熱器９を配置し、下部にファン１０を配置して構成される。 When the conventional pump is used in a cooling device that cools a heat generating member such as an electric component, for example, the configurations shown in FIGS. 11 and 12 can be considered. In this case, the pump 1 has a casing 2 with a suction port 3 and a discharge port 4 oriented in the same direction. The suction port 3 and the discharge port 4 are arranged close to each other.
On the other hand, the heat radiating portion 5 has a radiator 9 disposed in the inside of the case 8 constituted by the case main body 6 and the case lid 7, particularly in the upper portion of the case main body 6, and the fan 10 in the lower portion. Arranged and configured.

ケース８は、ケース主体６とケース蓋体７のそれぞれファン１０と対向する部分（下部）に、吸気口１１，１２を有し、ケース主体６の上面部に、吐気口１３を有する。
放熱器９は、横置きＵ字形のパイプ１４に多数のフィン１５を付設して構成され、パイプ１４の内部には冷却用の流体、この場合、液体が入れられる。
ファン１０は、内蔵したモータ（図示省略）により回転される。 The case 8 has air inlets 11 and 12 at portions (lower portions) of the case main body 6 and the case lid 7 that face the fan 10, and an air outlet 13 at the upper surface of the case main body 6.
The radiator 9 is configured by attaching a large number of fins 15 to a horizontal U-shaped pipe 14, and a cooling fluid, in this case, a liquid, is placed inside the pipe 14.
The fan 10 is rotated by a built-in motor (not shown).

そして、パイプ１４の入口部１６と出口部１７がポンプ１の吐出口４及び吸入口３の位置に合わせて折曲されており、この入口部１６と出口部１７にそれぞれ連結パイプ１８，１９によってポンプ１の吐出口４及び吸入口３が連結される。
この構成で、ポンプ１は、ケーシング２の図示しないインペラ（ポンプ溝）と対向した面２ａを電気部品等の発熱部材に密接させるようになっており、従って、その面２ａを有する部分が発熱部材から熱を受ける受熱部として機能する。 The inlet portion 16 and the outlet portion 17 of the pipe 14 are bent in accordance with the positions of the discharge port 4 and the suction port 3 of the pump 1, and are connected to the inlet portion 16 and the outlet portion 17 by connecting pipes 18 and 19, respectively. The discharge port 4 and the suction port 3 of the pump 1 are connected.
With this configuration, the pump 1 is configured so that a surface 2a of the casing 2 facing an impeller (pump groove) (not shown) is in close contact with a heat generating member such as an electric component. Therefore, a portion having the surface 2a is a heat generating member. It functions as a heat receiving part that receives heat from.

この状態で、ポンプ１を作動させれば、インペラが図示しないモータの駆動力で回転されることにより、放熱器９のパイプ１４内にある液体を、矢印Ａで示すように、吸入口３からポンプ室内に吸入し、吐出口４から吐出する。これによって、放熱器９のパイプ１４内にある液体が、ポンプ１のポンプ室とパイプ１４を通じて循環され、その過程で、電気部品等の発熱部材が発した熱をポンプ１のケーシング２（受熱部）を介して奪う。   When the pump 1 is operated in this state, the impeller is rotated by a driving force of a motor (not shown), so that the liquid in the pipe 14 of the radiator 9 is discharged from the suction port 3 as indicated by an arrow A. The air is sucked into the pump chamber and discharged from the discharge port 4. As a result, the liquid in the pipe 14 of the radiator 9 is circulated through the pump chamber and the pipe 14 of the pump 1, and in the process, heat generated by a heating member such as an electrical component is transferred to the casing 2 (heat receiving portion) of the pump 1. Take away through).

又、このとき、放熱部５では、ファン１０が回転されることにより、ケース８外の空気を、矢印Ｂで示すように、吸気口１１，１２からケース８内に吸入し、放熱器９のフィン１５の各間を通して吐気口１３から吐出する。かくして、放熱器９が冷却され、該放熱器９のパイプ１４内を通る液体が冷却される。
そして、その冷却された液体が前記ポンプ１により吸入されるものであり、これを繰り返して、上記電気部品等の発熱部材が冷却される。 At this time, in the heat dissipating section 5, the fan 10 is rotated so that the air outside the case 8 is sucked into the case 8 from the air inlets 11 and 12 as indicated by the arrow B, and the radiator 9 The gas is discharged from the air outlet 13 through each of the fins 15. Thus, the radiator 9 is cooled, and the liquid passing through the pipe 14 of the radiator 9 is cooled.
Then, the cooled liquid is sucked by the pump 1, and the heat generating member such as the electric component is cooled by repeating this.

しかしながら、こうしたものの場合、ポンプ１と放熱部５との連結部分（図示例ではパイプ１４の入口部１６と出口部１７の部分）がそれぞれ２箇所で鋭角に曲がり、しかも、その配管が長くなることで、流路の圧力損失が増し、流体の流量及び流速が低下するために、冷却性能が充分に得られない。   However, in such a case, the connecting portion between the pump 1 and the heat radiating portion 5 (in the illustrated example, the portion of the inlet portion 16 and the outlet portion 17 of the pipe 14) bends at two acute angles, and the piping becomes longer. Thus, the pressure loss of the flow path increases and the flow rate and flow rate of the fluid decrease, so that sufficient cooling performance cannot be obtained.

ケーシング蓋体２４には、ケーシング主体２３側とは反対側に円形の凹陥部３７を形成し、ケーシング主体２３側に、図１に示すように、上記凹陥部３７を囲繞するリング状の凹陥部３８を形成している。更に、上記凹陥部３７の外底部（ケーシング主体２３側）の中心部には軸受部３９を形成しており、この軸受部３９によって前記インペラ２９の軸３２の残る片側（ケーシング蓋体２４側の部位）を支承するようにしている。   The casing lid 24 is formed with a circular recess 37 on the side opposite to the casing main body 23 side, and on the casing main body 23 side, as shown in FIG. 1, a ring-shaped recess that surrounds the recess 37. 38 is formed. Further, a bearing portion 39 is formed at the center of the outer bottom portion (casing main body 23 side) of the recessed portion 37, and by this bearing portion 39, the remaining one side (on the casing lid body 24 side) of the shaft 32 of the impeller 29. Part) is supported.

ケーシング蓋体２４の凹陥部３７には、固定子４０を装着している。この固定子４０は、複数の磁極４１ａを有する固定子鉄心４１と、その各磁極４１ａに巻回された固定子巻線４２とにより構成しており、ケーシング蓋体２４をケーシング主体２３に組み合わせることによって、図３に示すように、前記永久磁石３６がケーシング蓋体２４のケーシング主体２３側の凹陥部３８内に位置し、上記固定子４０の各磁極４１ａの外周面が、ケーシング蓋体２４のケーシング主体２３側とは反対側の凹陥部３７の周壁３７ａを間に置いて、前記永久磁石３６の内周面に径方向の内側より対向している。   A stator 40 is attached to the recessed portion 37 of the casing lid 24. The stator 40 includes a stator core 41 having a plurality of magnetic poles 41 a and a stator winding 42 wound around each of the magnetic poles 41 a, and the casing lid 24 is combined with the casing main body 23. 3, the permanent magnet 36 is positioned in the recessed portion 38 on the casing main body 23 side of the casing lid 24, and the outer peripheral surface of each magnetic pole 41 a of the stator 40 corresponds to the casing lid 24.

かくして、インペラ２９と、磁性リング３５、及び永久磁石３６とで回転子４３を構成し、この回転子４３と固定子４０とでモータ４４を構成している。
なお、組み合わせたケーシング主体２３とケーシング蓋体２４は、図１及び図２に示す複数のねじ４５によって結合固定している。ポンプ２１は、以上の構成である。 Thus, the impeller 29, the magnetic ring 35, and the permanent magnet 36 constitute a rotor 43, and the rotor 43 and the stator 40 constitute a motor 44.
Note that the combined casing main body 23 and casing lid 24 are coupled and fixed by a plurality of screws 45 shown in FIGS. 1 and 2. The pump 21 has the above configuration.

図４及び図５は、以上のポンプ２１を使用した冷却装置５１を示している。この冷却装置５１は、基本的には、先の図１１及び図１２に示した冷却装置と同じ構成であり、従って、ポンプ２１のほか、放熱部５２を有している。この放熱部５２は、ケース主体５３とケース蓋体５４とで構成されるケース５５の内部、特にはケース主体５３の内部の上部に放熱器５６を配置し、下部にファン５７を配置している。   4 and 5 show a cooling device 51 using the pump 21 described above. The cooling device 51 basically has the same configuration as the cooling device shown in FIGS. 11 and 12, and therefore has a heat radiating portion 52 in addition to the pump 21. In the heat dissipating part 52, a heat radiator 56 is arranged inside a case 55 constituted by a case main body 53 and a case lid 54, in particular, an upper part inside the case main body 53, and a fan 57 is arranged below the case main body 53. .

ケース５５は、ケース主体５３とケース蓋体５４のそれぞれファン５７と対向する部分（下部）に、吸気口５８，５９を有し、ケース蓋体５４の上面部に、吐気口６０を有している。
放熱器５６は、横置きＵ字形のパイプ６１に多数のフィン６２を付設して構成しており、パイプ６１の内部には冷却用の流体、この場合、液体を入れている。
ファン５７は、内蔵したモータ（図示省略）により回転される。 The case 55 has air intakes 58 and 59 in portions (lower portions) of the case main body 53 and the case lid 54 that face the fan 57, respectively, and an air outlet 60 on the upper surface of the case lid 54. Yes.
The radiator 56 is configured by attaching a large number of fins 62 to a horizontally placed U-shaped pipe 61, and a cooling fluid, in this case, a liquid, is placed inside the pipe 61.
The fan 57 is rotated by a built-in motor (not shown).

ここで、パイプ６１は、その長さをできる限り大きくして放熱効果を高く得るべく、図中上下の間隔を離し、大形化している
そして、そのパイプ６１の入口部６３と出口部６４とを、ポンプ２１の吸入口２６及び吐出口２７の位置及び指向方向に合わせて少し（鈍角に）折曲しており、この入口部６３と出口部６４とに、それぞれ連結パイプ６５，６６によってポンプ２１の吐出口２７及び吸入口２６を連結している。従って、この場合、パイプ６１の入口部６３と出口部６４は、ポンプ２１と放熱器５６との連結部分であり、これらが鈍角を成している。 Here, the pipe 61 is enlarged by increasing the length of the pipe 61 as much as possible so as to obtain a high heat dissipation effect. Is slightly bent (obtuse angle) in accordance with the position and the direction of the suction port 26 and the discharge port 27 of the pump 21, and the inlet 63 and the outlet 64 are connected to the pump by connecting pipes 65 and 66, respectively. 21 discharge ports 27 and suction ports 26 are connected. Therefore, in this case, the inlet portion 63 and the outlet portion 64 of the pipe 61 are a connecting portion between the pump 21 and the radiator 56, and they form an obtuse angle.

この構成で、ポンプ２１は、ケーシング２２のインペラ２９（ポンプ溝３０）と対向したケーシング主体２３の表面２３ａを電気部品等の発熱部材に密接させるようになっており、従って、その表面２３ａを有するケーシング主体２３が発熱部材から熱を受ける受熱部として機能するもので、要するに、冷却装置５１は、上記放熱部５２のほかに、受熱部を有し、その受熱部をポンプ２１が一体的に有している。又、この関係上、ポンプ２１は、ケーシング主体２３を熱伝導性の良い部材、特には金属で構成している。   With this configuration, the pump 21 is configured to bring the surface 23a of the casing main body 23 facing the impeller 29 (pump groove 30) of the casing 22 into close contact with a heat generating member such as an electrical component, and thus has the surface 23a. The casing main body 23 functions as a heat receiving portion that receives heat from the heat generating member. In short, the cooling device 51 has a heat receiving portion in addition to the heat radiating portion 52, and the pump 21 integrally has the heat receiving portion. doing. Further, in this relation, the pump 21 includes the casing main body 23 made of a member having good thermal conductivity, particularly metal.

この状態で、ポンプ２１におけるモータ４４の固定子巻線４２に通電すれば、インペラ２９を含む回転子４３が回転し、そのインペラ２９の回転によるポンプ溝３０の送液作用により、ポンプ２１が、放熱器５６のパイプ６１内にある液体を、矢印Ｃで示すように、連結パイプ６６を通じて吸入口２６からポンプ室２５内に吸入し、吐出口２７から連結パイプ６５を通じて吐出する。これによって、放熱器５６のパイプ６１内にある液体が、ポンプ２１のポンプ室２５とパイプ６１を通じて循環され、その過程で、電気部品等の発熱部材が発した熱をポンプ２１のケーシング主体２３（受熱部）を介して奪う。   In this state, if the stator winding 42 of the motor 44 in the pump 21 is energized, the rotor 43 including the impeller 29 rotates, and the pump 21 is fed by the liquid feeding action of the pump groove 30 by the rotation of the impeller 29. As indicated by an arrow C, the liquid in the pipe 61 of the radiator 56 is sucked into the pump chamber 25 from the suction port 26 through the connection pipe 66 and discharged through the connection pipe 65 from the discharge port 27. As a result, the liquid in the pipe 61 of the radiator 56 is circulated through the pump chamber 25 and the pipe 61 of the pump 21, and in the process, the heat generated by the heat generating member such as an electrical component is transferred to the casing main body 23 ( Take away via the heat receiving part).

又、このとき、放熱部５２では、ファン５７が回転されることにより、ケース５５外の空気を、矢印Ｄで示すように、吸気口５８，５９からケース５５内に吸入し、放熱器５６のフィン６２の各間を通して吐気口６０から吐出する。かくして、放熱器５６が冷却され、該放熱器５６のパイプ６１内を通る液体が冷却される。
そして、その冷却された液体が前記ポンプ２１により吸入されるものであり、これを繰り返して、上記電気部品等の発熱部材が冷却される。 At this time, in the heat dissipating section 52, the fan 57 is rotated to suck the air outside the case 55 into the case 55 through the intake ports 58 and 59 as indicated by the arrow D. The air is discharged from the air outlet 60 through each of the fins 62. Thus, the radiator 56 is cooled, and the liquid passing through the pipe 61 of the radiator 56 is cooled.
Then, the cooled liquid is sucked by the pump 21, and this is repeated to cool the heat generating member such as the electric component.

なお、ポンプ２１による送液の量は、モータ４４の回転子４３の回転速度を変化させることによって変化させることが可能であり、それによって、上記電気部品等の発熱部材を冷却する性能も変化させることができる。   Note that the amount of liquid fed by the pump 21 can be changed by changing the rotation speed of the rotor 43 of the motor 44, thereby changing the performance of cooling the heat generating member such as the electric component. be able to.

本構成のポンプ２１は、このように、例えば電気部品等の発熱部材を冷却する冷却装置５１に使用されるものであるが、吸入口２６及び吐出口２７が互いに異なる方向に指向するようにしている。これにより、連結相手部材である放熱部５２の放熱器５６におけるパイプ６１の入口部６３及び出口部６４と、連結部分を鋭角に曲げず（それぞれ１箇所で鈍角に曲げるに留めて）、且つ、配管を長くすることなく連結できる。よって、流路の圧力損失を少なく留め、流体の流量及び流速を低下させることのないようにできる。   The pump 21 of this configuration is used in the cooling device 51 that cools a heat generating member such as an electrical component in this way, but the suction port 26 and the discharge port 27 are directed in different directions. Yes. Thereby, the inlet part 63 and the outlet part 64 of the pipe 61 in the radiator 56 of the heat radiating part 52, which is a connection partner member, and the connection part are not bent at an acute angle (only bend at an obtuse angle at one place), and Can be connected without lengthening the piping. Therefore, the pressure loss of the flow path can be kept small, and the flow rate and flow rate of the fluid can be prevented from being reduced.

又、本構成の冷却装置５１によれば、上述のポンプ２１を使用して構成しているので、流体を冷却用として、圧力損失少なく、流量及び流速も低下させることなく、受熱部及び放熱部を流通させ得ることになり、よって、冷却性能を充分に得ることができる。
更に、本構成の冷却装置５１によれば、受熱部をポンプ２１と一体的に有するものであり、その分、冷却装置５１をコンパクトに実現できる。なお、このように受熱部をポンプ２１と一体的に有する構成としては、ポンプ２１のケーシング２２に熱伝導性の良い部材を別途装着して、それを発熱部材に密接させるようにしても良い。 Further, according to the cooling device 51 of this configuration, since the above-described pump 21 is used, the heat receiving portion and the heat radiating portion are used for cooling the fluid, with little pressure loss, and without reducing the flow rate and flow velocity. Therefore, the cooling performance can be sufficiently obtained.
Furthermore, according to the cooling device 51 of this structure, it has a heat receiving part integrally with the pump 21, and the cooling device 51 is realizable compactly. In addition, as a structure which has a heat receiving part integrally with the pump 21 in this way, you may make it attach the member with good heat conductivity to the casing 22 of the pump 21, and make it closely_contact | adhere to a heat generating member.

［第６実施例］
図１０に示す第６実施例においては、ポンプ２１を電気機器、中でも、パーソナルコンピュータ１１１に使用している。詳細には、パーソナルコンピュータ１１１の本体部１１２がキーボード（図示省略）を具え、本体部１１２に開閉回動可能に設けられた蓋部１１３が液晶による表示部（これも図示省略）を具えた一般的構成に対し、その本体部１１２の内部（キーボードの下側）に設けられた発熱部材としてのＣＰＵ１１４に、ポンプ２１の前記ケーシング本体２３（受熱部）を密接させている。 [Sixth embodiment]
In the sixth embodiment shown in FIG. 10, the pump 21 is used for an electric device, particularly for the personal computer 111. More specifically, the main body 112 of the personal computer 111 has a keyboard (not shown), and the lid 113 provided on the main body 112 so as to be capable of opening and closing is generally provided with a liquid crystal display (also not shown). In contrast to the general configuration, the casing main body 23 (heat receiving portion) of the pump 21 is brought into close contact with the CPU 114 as a heat generating member provided inside the main body portion 112 (under the keyboard).

そして、冷却装置１１５としては、蓋部１１３の内部（表示部の裏側）に、放熱部１１６を設けており、これの入口部１１７と上記ポンプ２１の吐出口２７とを連結パイプ１１８により接続し、放熱部１１６の出口部１１９とポンプ２１の吸入口２６とを連結パイプ１２０により接続している。   As the cooling device 115, a heat radiating portion 116 is provided inside the lid portion 113 (on the back side of the display portion), and the inlet portion 117 thereof and the discharge port 27 of the pump 21 are connected by a connecting pipe 118. The outlet portion 119 of the heat radiating portion 116 and the suction port 26 of the pump 21 are connected by a connecting pipe 120.

従って、この構成でも、ポンプ２１を作動させれば、放熱部１１６内の流体（この場合も、例えば液体）が、連結パイプ１２０を通じてポンプ２１の吸入口２６からポンプ室２５内に吸入され、吐出口２７から連結パイプ１１８を通じて吐出されることにより、放熱部１１６内の流体が循環され、その過程で、ＣＰＵ１１４が発した熱をポンプ２１のケーシング主体２３（受熱部）を介して奪う。
又、このとき、放熱部１１６では、そこを通る液体が冷却され、この冷却された液体が前記ポンプ２１により吸入されるものであり、これを繰り返して、上記ＣＰＵ１１４（発熱部材）が冷却される。 Accordingly, even in this configuration, when the pump 21 is operated, the fluid (for example, liquid in this case) in the heat radiating portion 116 is sucked into the pump chamber 25 from the suction port 26 of the pump 21 through the connection pipe 120 and discharged. By being discharged from the outlet 27 through the connecting pipe 118, the fluid in the heat radiating section 116 is circulated, and in the process, the heat generated by the CPU 114 is taken through the casing main body 23 (heat receiving section) of the pump 21.
At this time, in the heat radiating section 116, the liquid passing therethrough is cooled, and the cooled liquid is sucked by the pump 21, and this is repeated to cool the CPU 114 (heat generating member). .

このものによれば、ポンプ２１の吸入口２６及び吐出口２７の指向方向が互いに異なることに応じて、パーソナルコンピュータ１１１の蓋部１１３に設けた放熱部１１６の入口部１１７及び出口部１１９と、ポンプ２１の吸入口２６及び吐出口２７との間を、連結パイプ１１８、１２０により、極力鋭角に曲げず、且つ、配管を極力長くすることなく連結できるので、流体を、圧力損失少なく、流量及び流速も低下させることなく流通させることができる。よって、ＣＰＵ１１４（発熱部材）の冷却性能を充分に得ることができる。   According to this, according to the directivity directions of the suction port 26 and the discharge port 27 of the pump 21 being different from each other, the inlet portion 117 and the outlet portion 119 of the heat radiating portion 116 provided in the lid portion 113 of the personal computer 111, The connection between the suction port 26 and the discharge port 27 of the pump 21 can be achieved by connecting pipes 118 and 120 without bending as sharply as possible and without making the pipe as long as possible. It is possible to circulate without reducing the flow rate. Therefore, sufficient cooling performance of the CPU 114 (heat generating member) can be obtained.

なお、この場合も、ポンプ２１は、受熱部を別体で有していても良い。又、ポンプ２１の吸入口２６と吐出口２７の指向方向は、パーソナルコンピュータ１１１の本体部１１２内における連結パイプ１１８、１２０の配管事情に合わせて、それらを逆に、又は第１実施例と同じ形態で異ならせるようにしても良い。更に、この場合も、ポンプ２１（吸入口２６）と放熱部１１６の出口部１１９との連結部分である連結パイプ１２０に鈍角の部分が存しているが、ポンプ２１の吸入口２６と吐出口２７の指向方向を逆にした場合には、ポンプ２１（吐出口２７）と放熱部１１６の入口部１１７との連結部分である連結パイプ１１８に鈍角の部分が存することになる。   Also in this case, the pump 21 may have a heat receiving part as a separate body. Further, the directing directions of the suction port 26 and the discharge port 27 of the pump 21 are reversed in accordance with the piping circumstances of the connection pipes 118 and 120 in the main body 112 of the personal computer 111, or the same as those in the first embodiment. You may make it vary with a form. Further, in this case as well, an obtuse angle portion exists in the connection pipe 120 which is a connection portion between the pump 21 (suction port 26) and the outlet portion 119 of the heat radiating unit 116, but the suction port 26 and the discharge port of the pump 21 When the directivity direction of 27 is reversed, an obtuse angle portion exists in the connection pipe 118, which is a connection portion between the pump 21 (discharge port 27) and the inlet portion 117 of the heat radiating portion 116.

このほか、本発明は上記し且つ図面に示した実施例にのみ限定されるものではなく、例えば、発熱部材の温度又は流体の温度を検知して、モータ４４の回転子４３の回転速度を変化させることにより、ポンプ２１による送液の量を変化させるようにしても良いなど、
