Japanese Patent No. 3170669

解決しようとする課題は、被冷却物の全体を均一に且つ効率良く気化冷却することのできる気化冷却装置を提供することである。   The problem to be solved is to provide an evaporative cooling apparatus that can uniformly and efficiently evaporate and cool the entire object to be cooled.

本発明は、被冷却物を冷却する気化冷却室を形成して、当該気化冷却室に冷却流体を供給すると共に、気化冷却室を吸引手段と接続して被冷却物を気化冷却するものにおいて、気化冷却室内に冷却流体の流下する冷却流体管路を配置して、当該冷却流体管路に冷却流体を外部に噴射する冷却流体噴射口を複数個設けると共に、冷却流体管路に冷却流体を霧化又は液滴化する超音波振動子を取り付けたものである。   The present invention forms a vaporization cooling chamber for cooling an object to be cooled, supplies a cooling fluid to the vaporization cooling chamber, and vaporizes and cools the object to be cooled by connecting the vaporization cooling chamber to suction means. A cooling fluid pipe through which the cooling fluid flows is arranged in the vaporization cooling chamber, and a plurality of cooling fluid injection ports for injecting the cooling fluid to the outside are provided in the cooling fluid pipe, and the cooling fluid is fogged in the cooling fluid pipe. An ultrasonic transducer for forming or droplets is attached.

本発明の気化冷却装置は、気化冷却室に冷却流体の流下する冷却流体管路を配置して、この冷却流体管路に冷却流体を外部に噴射する冷却流体噴射口を複数個設けたことによって、複数の冷却流体噴射口から気化冷却室の全体に且つ直接に冷却流体を供給することができ、被冷却物の全体をムラなく気化冷却することができる。また、気化冷却室内で被冷却物の熱を奪って蒸発気化した冷却流体の気化蒸気を、冷却流体管路に取り付けた超音波振動子によって発生した霧化あるいは液滴化された冷却流体で冷却して凝縮させることによって、気化蒸気の気化冷却室内での対流を促進して冷却効率を向上させることができる。   The evaporative cooling device of the present invention includes a cooling fluid conduit in which a cooling fluid flows down in a vaporization cooling chamber, and a plurality of cooling fluid injection ports for injecting the cooling fluid to the outside are provided in the cooling fluid conduit. The cooling fluid can be supplied directly to the entire vaporization cooling chamber from the plurality of cooling fluid ejection ports, and the entire object to be cooled can be vaporized and cooled without unevenness. In addition, the vaporized vapor of the cooling fluid that evaporates by removing the heat of the object to be cooled in the vaporization cooling chamber is cooled by the atomized or dropletized cooling fluid generated by the ultrasonic vibrator attached to the cooling fluid conduit. By condensing the gas, the convection of the vaporized vapor in the vaporized cooling chamber can be promoted, and the cooling efficiency can be improved.

本発明は、冷却流体管路に冷却流体を外部へ噴射する冷却流体噴射口を設けたものであるが、冷却流体噴射口としては、冷却流体管路に切欠等の開口部を複数個設けることも、あるいは、冷却流体管路に噴射ノズル等を取り付けて冷却流体噴射口とすることもできる。   In the present invention, a cooling fluid injection port for injecting a cooling fluid to the outside is provided in the cooling fluid pipeline. As the cooling fluid injection port, a plurality of openings such as notches are provided in the cooling fluid pipeline. Alternatively, an injection nozzle or the like can be attached to the cooling fluid conduit to form a cooling fluid injection port.

本実施例においては、気化冷却室として反応釜1のジャケット部2を用いた例を示す。反応釜1の内部に入れた図示しない被冷却物を、ジャケット部2に供給する冷却源としての冷却流体によって冷却するものである。   In the present embodiment, an example in which the jacket portion 2 of the reaction kettle 1 is used as a vaporization cooling chamber is shown. An object to be cooled (not shown) placed inside the reaction kettle 1 is cooled by a cooling fluid as a cooling source supplied to the jacket portion 2.

反応釜1のほぼ全周にわたりジャケット部2を形成して、このジャケット部2に吸引手段としての組み合わせ真空ポンプ4、及び、冷却流体供給管5を接続する。冷却流体供給管5は、気化冷却室としてのジャケット部2内に配置した冷却流体管路6と接続する。   A jacket portion 2 is formed over substantially the entire circumference of the reaction kettle 1, and a combined vacuum pump 4 and a cooling fluid supply pipe 5 are connected to the jacket portion 2 as suction means. The cooling fluid supply pipe 5 is connected to a cooling fluid pipe 6 disposed in the jacket portion 2 as a vaporization cooling chamber.

冷却流体供給管5の下方部は、組み合わせ真空ポンプ4の循環路15の一部と接続すると共に、上方部を冷却流体管路6の一端部と接続する。冷却流体管路6は、ジャケット部2内に螺旋状に配置して、図示はしないが冷却流体管路6の反応釜1側に複数の冷却流体噴射口を設ける。   The lower part of the cooling fluid supply pipe 5 is connected to a part of the circulation path 15 of the combination vacuum pump 4 and the upper part is connected to one end part of the cooling fluid pipe 6. The cooling fluid pipe 6 is spirally disposed in the jacket portion 2 and a plurality of cooling fluid injection ports are provided on the reaction kettle 1 side of the cooling fluid pipe 6 (not shown).

冷却流体管路6の下部に、超音波振動子18を取り付ける。この超音波振動子18が発生する超音波振動によって、冷却流体管路6の冷却流体の一部を霧状あるいは液滴状にしてジャケット部2内へ飛散させ供給することができる。このように、ジャケット部2内へ冷却液を供給することによって、ジャケット部2内の気化蒸気を冷却して凝縮させることができ、ジャケット部2内での気化蒸気の対流が促進され、反応釜1の冷却効率を向上させることができる。 An ultrasonic transducer 18 is attached to the lower part of the cooling fluid conduit 6. By the ultrasonic vibration generated by the ultrasonic vibrator 18, a part of the cooling fluid in the cooling fluid conduit 6 can be sprayed into the jacket portion 2 in the form of a mist or a droplet. Thus, by supplying the cooling liquid into the jacket portion 2, the vaporized vapor in the jacket portion 2 can be cooled and condensed, and the convection of the vaporized vapor in the jacket portion 2 is promoted, and the reaction kettle 1 cooling efficiency can be improved.

ジャケット部2の左側上部には、流量調節弁7を介在した蒸気供給管8を接続する。この蒸気供給管8から、所定圧力すなわち温度の加熱用蒸気が、ジャケット部2へ供給されることによって、反応釜1内の被熱交換物を加熱することもできるものである。   A steam supply pipe 8 with a flow rate adjusting valve 7 interposed is connected to the upper left portion of the jacket part 2. By supplying steam for heating at a predetermined pressure, that is, temperature from the steam supply pipe 8 to the jacket portion 2, the heat exchanged material in the reaction kettle 1 can be heated.

ジャケット部2の右側下方に排出管9を接続して、組み合わせ真空ポンプ4のエゼクタ10と接続する。排出管9には、開閉弁11と気液分離器12をそれぞれ取り付ける。気液分離器12は、排出管9から流下してくる蒸気と液体をそれぞれ分離することができるものであり、分離された蒸気は蒸気エゼクタ3へ吸引され、一方、分離された液体は管路20を通って下方のエゼクタ10へ吸引される。   A discharge pipe 9 is connected to the lower right side of the jacket portion 2 and connected to the ejector 10 of the combination vacuum pump 4. An open / close valve 11 and a gas-liquid separator 12 are attached to the discharge pipe 9. The gas-liquid separator 12 can separate the vapor and the liquid flowing down from the discharge pipe 9, respectively, and the separated vapor is sucked into the vapor ejector 3, while the separated liquid is a pipe line. 20 is sucked through the lower ejector 10.

蒸気エゼクタ3は、蒸気供給管8を分岐した分岐管21に入口側を接続し、出口側を管路22によって再度、蒸気供給管8の流量調節弁7の手前側に接続したもので、排出管9から流下してくるジャケット部2内の一部の蒸気を、蒸気エゼクタ3で吸引して再度、蒸気供給管8からジャケット部2へ供給することによって、ジャケット部2内の蒸気を強制的に循環させることができるものである。   The steam ejector 3 has an inlet side connected to a branch pipe 21 branched from the steam supply pipe 8 and an outlet side connected again to the front side of the flow rate control valve 7 of the steam supply pipe 8 by a pipe line 22. A part of the steam in the jacket part 2 flowing down from the pipe 9 is sucked by the steam ejector 3 and supplied again from the steam supply pipe 8 to the jacket part 2, thereby forcing the steam in the jacket part 2. It can be circulated.

組み合わせ真空ポンプ4を、エゼクタ10とタンク13と循環ポンプ14を順次に循環路15で連通して形成する。タンク13の上部には、冷却流体としての冷却水を補給する冷却水補給管16を接続する。循環路15の一部を分岐して余剰水排出管17と、上述した冷却流体供給管5をそれぞれ接続する。冷却流体供給管5は、組み合わせ真空ポンプ4を循環する循環流体の一部を、ジャケット部2の冷却流体管路6へ供給することによって、反応釜1を気化冷却することができるものである。   The combination vacuum pump 4 is formed by sequentially communicating the ejector 10, the tank 13, and the circulation pump 14 through the circulation path 15. A cooling water supply pipe 16 for supplying cooling water as a cooling fluid is connected to the upper portion of the tank 13. A part of the circulation path 15 is branched to connect the excess water discharge pipe 17 and the above-described cooling fluid supply pipe 5. The cooling fluid supply pipe 5 can evaporate and cool the reaction kettle 1 by supplying a part of the circulating fluid circulating through the combination vacuum pump 4 to the cooling fluid pipe 6 of the jacket portion 2.

ジャケット部2の左側面に、管路23と開閉弁24を介在して組み合わせ真空ポンプ4のエゼクタ10と接続する。この管路23は、ジャケット部2内で発生した冷却流体の気化蒸気をエゼクタ10へ吸引するためのものである。 The left side surface of the jacket portion 2 is connected to the ejector 10 of the combination vacuum pump 4 via a pipe line 23 and an on-off valve 24. The conduit 23 is for sucking vaporized vapor of the cooling fluid generated in the jacket portion 2 to the ejector 10.

反応釜1内の被冷却物を冷却する場合は、冷却流体供給管5から冷却流体を冷却流体管路6内へ供給して、冷却流体管路6内を冷却流体で満たすと同時に、図示しない冷却流体管路6の反応釜1側に設けた複数の冷却流体噴射口から反応釜1の外表面全体へ冷却流体を噴射する。   When the object to be cooled in the reaction kettle 1 is cooled, the cooling fluid is supplied from the cooling fluid supply pipe 5 into the cooling fluid pipe 6 to fill the cooling fluid pipe 6 with the cooling fluid, and at the same time, not shown. Cooling fluid is ejected from the plurality of cooling fluid ejection ports provided on the reaction kettle 1 side of the cooling fluid pipe 6 to the entire outer surface of the reaction kettle 1.

一方、組み合わせ真空ポンプ4の循環ポンプ14を駆動して、エゼクタ10の発生する吸引力で排出管9または管路23を介してジャケット部2内を所定の圧力状態、例えば、大気圧以下の真空状態、とすることにより、反応釜1の外表面へ噴射される冷却流体が反応釜1内の被冷却物の熱を奪って蒸発気化することにより、その蒸発潜熱によって被冷却物を気化冷却することができる。 On the other hand, the circulation pump 14 of the combination vacuum pump 4 is driven, and the inside of the jacket portion 2 is evacuated to a predetermined pressure state, for example, a vacuum below atmospheric pressure, through the discharge pipe 9 or the pipe line 23 by the suction force generated by the ejector 10. By setting the state, the cooling fluid injected to the outer surface of the reaction kettle 1 takes the heat of the object to be cooled in the reaction kettle 1 and evaporates and vaporizes and cools the object to be cooled by the latent heat of vaporization. be able to.

このように反応釜1を冷却する場合に、冷却流体管路6の複数の冷却流体噴射口から反応釜1の外表面の全体に且つ均一に冷却流体を供給することができ、反応釜1の全体をムラなく気化冷却することができる。また、ジャケット部2内に発生した気化蒸気の一部を、超音波振動子18により発生した霧化あるいは液滴化された冷却流体で冷却して凝縮することによって、ジャケット部2内での気化蒸気の対流が促進され、被冷却物の冷却効率を向上させることができる。 When the reaction kettle 1 is cooled in this way, the cooling fluid can be uniformly and uniformly supplied to the entire outer surface of the reaction kettle 1 from the plurality of cooling fluid injection ports of the cooling fluid conduit 6. The whole can be vaporized and cooled evenly. Further, a part of the vaporized vapor generated in the jacket part 2 is cooled and condensed with the atomized or dropletized cooling fluid generated by the ultrasonic vibrator 18, thereby vaporizing in the jacket part 2. Steam convection is promoted, and the cooling efficiency of the object to be cooled can be improved.

ジャケット部2で被冷却物を冷却した冷却流体の気化蒸気及び気化しきれなかった冷却流体の一部は、排出管9または管路23を通ってエゼクタ10に吸引されタンク13に至る。   The vaporized vapor of the cooling fluid that has cooled the object to be cooled by the jacket portion 2 and a part of the cooling fluid that could not be vaporized are sucked into the ejector 10 through the discharge pipe 9 or the pipe line 23 and reach the tank 13.

エゼクタ10で発生することのできる吸引力は、エゼクタ10を流下する流体の温度によって決まるために、冷却水補給管16から適宜所定温度の冷却水をタンク13へ補給することによって、エゼクタ10を流下する流体温度を調節して、エゼクタ10の吸引力をコントロールすることができる。   Since the suction force that can be generated by the ejector 10 is determined by the temperature of the fluid flowing down the ejector 10, the cooling water supply pipe 16 appropriately supplies cooling water to the tank 13 by appropriately supplying the cooling water to the tank 13. The suction force of the ejector 10 can be controlled by adjusting the fluid temperature.

一方、反応釜1内の被加熱物を加熱する場合は、蒸気供給管8から加熱に適した温度の蒸気をジャケット部2へ供給することによって、蒸気が反応釜1内の被加熱物に熱を与えて加熱する。加熱により蒸気の凝縮した復水と一部の蒸気は、排出管9と気液分離器12を通って、蒸気の分離された復水だけが管路20からエゼクタ10に吸引されタンク13に至ると共に、復水の分離された蒸気は、蒸気エゼクタ3に吸引され、管路22と蒸気供給管8から再度ジャケット部2へ供給される。   On the other hand, when the object to be heated in the reaction kettle 1 is heated, the steam is heated to the object to be heated in the reaction kettle 1 by supplying steam at a temperature suitable for heating from the steam supply pipe 8 to the jacket portion 2. Give and heat. Condensate condensed with steam by heating and a part of the steam pass through the discharge pipe 9 and the gas-liquid separator 12, and only the condensate from which the steam has been separated is sucked into the ejector 10 from the pipe line 20 and reaches the tank 13. At the same time, the steam separated from the condensate is sucked into the steam ejector 3 and supplied to the jacket portion 2 again from the conduit 22 and the steam supply pipe 8.
