Description

本発明はファンと噴霧ノズルを備えた冷却装置に関するものである。 The present invention relates to a cooling device including a fan and a spray nozzle.

従来、この種の冷却装置は、ファンが吹き出した気流をガイドケーシングで整流し、霧を搬送している。（例えば特許文献１）
図１は、特許文献１に記載された従来の冷却装置を示すものである。従来の冷却装置は、図１に示すように、送風機１０１と、送風機１０１の周囲に配置された筐体１０２と、筐体１０２下面に設けられた吹出口１０３および吸込口１０４と、送風機１０１と吹出口１０３を接続し、送風機１０１が吹き出した気流を整流するためのガイドケーシング１０６と、吹出口１０３から吹き出した気流にミストを噴霧するための噴霧ノズル１０５を有する。 Conventionally, in this type of cooling device, the airflow blown out by the fan is rectified by the guide casing to convey the mist. (For example, Patent Document 1)

しかしながら、従来の構成では送風機から出た気流と冷却装置の吸込口下方の空間との圧力差で生じる対流によって、ミストが巻き上がり筐体下面にミストが付着する課題を有していた。 However, in the conventional configuration, there is a problem that the mist winds up and adheres to the lower surface of the housing due to the convection generated by the pressure difference between the airflow emitted from the blower and the space below the suction port of the cooling device.

加えて、外乱によって筐体を横切るような気流が生じた場合も、噴霧ノズルから噴霧されたミストがその気流の流れに乗り筐体下面を流れるため、筐体下面にミストが付着して同様の課題が生じていた。 In addition, even when an air flow that crosses the housing is generated due to disturbance, the mist sprayed from the spray nozzle rides on the flow of the air flow and flows on the lower surface of the housing, so that the mist adheres to the lower surface of the housing and the same applies. There was a problem.

結果として、冷却装置からの液だれや冷却装置の筐体表面に水垢やスケールが発生し、不快感の増大や美観を損ねる等の問題が生じていた。 As a result, dripping from the cooling device and water stains and scales are generated on the surface of the housing of the cooling device, which causes problems such as increased discomfort and spoiling the aesthetic appearance.

本発明は、従来の課題を解決するもので、気流を生じさせることで筐体下面へのミストの付着を防止する冷却装置を提供することを目的とする。 The present invention solves the conventional problems, and an object of the present invention is to provide a cooling device that prevents mist from adhering to the lower surface of a housing by generating an air flow.

従来の課題を解決するために、本発明の冷却装置は、空気の流れを発生させる送風機と、下部に略円形の開口を設けた筐体と、筐体と送風機を連通する第一の吸込口と、筐体の内部空間に設けられ、開口内部に略同心円上に配置された略円筒状の内円筒部材と、内円筒部材に設けられ、筐体と内円筒部材を連通する第二の吸込口と、開口と内円筒部材の外周面で形成された環状の第一の吹出口と、内円筒部材に設けられた噴霧ノズルと、内円筒部材の下部に設けられた略円形の第一の底板と、第一の底板に設けられ、第一の底板の中心を原点として略円形に開口した底板開口と、第一の底板の下方の空間に設けられ、底板開口の略同心円上にあり、底板開口の直径よりも大きい外径を有する略円形の第二の底板と、第一の底板の下面と第二の底板の上面から形成された第二の吹出口としたものである。 In order to solve the conventional problems, the cooling device of the present invention includes a blower that generates an air flow, a housing provided with a substantially circular opening at the bottom, and a first suction port that communicates the housing and the blower. A second suction that is provided in the inner space of the housing and is provided in the inner cylindrical member and is provided in the inner cylindrical member and is arranged in a substantially concentric circle inside the opening. An annular first outlet formed on the mouth, an opening and the outer peripheral surface of the inner cylindrical member, a spray nozzle provided on the inner cylindrical member, and a substantially circular first first provided on the lower part of the inner cylindrical member. The bottom plate, the bottom plate opening provided on the first bottom plate and opened substantially circularly with the center of the first bottom plate as the origin, and the bottom plate opening provided in the space below the first bottom plate, located on substantially concentric circles of the bottom plate opening. It is a substantially circular second bottom plate having an outer diameter larger than the diameter of the bottom plate opening, and a second air outlet formed from the lower surface of the first bottom plate and the upper surface of the second bottom plate.

これによって、第一の吹出口から送風されるミストを含んだ気流が対流により第一の底板近傍に流れても、気流に含まれるミストは、第二の吹出口からの送風で生じる第一の底
板の中心から外側に向かって流れる空気層により第一の底板に付着することなく第一の底板外縁に流れる。 As a result, even if the airflow containing the mist blown from the first outlet flows near the first bottom plate due to convection, the mist contained in the airflow is the first generated by the blowing from the second outlet. The air layer flowing from the center of the bottom plate to the outside flows to the outer edge of the first bottom plate without adhering to the first bottom plate.

また、本発明の冷却装置は、第二の吹出口の開口面積が第一の吹出口の開口面積よりも狭いことを特徴とする。 Further, the cooling device of the present invention is characterized in that the opening area of the second outlet is narrower than the opening area of the first outlet.

これによって、外乱による気流の流れが特に強く、冷却装置を横切る様に気流が生じたときでも、第二の吹出口からの吹出し気流の流速が速くなり外乱に対する抗力が増加するため、外乱に流されること無く第一の底板の中心から外側に向かって流れる空気層を形成する。 As a result, the flow of the airflow due to the disturbance is particularly strong, and even when the airflow is generated so as to cross the cooling device, the flow velocity of the airflow from the second outlet becomes faster and the drag against the disturbance increases, so that the airflow flows to the disturbance. It forms an air layer that flows outward from the center of the first bottom plate without being damaged.

底板全面に渡り、底板の下面に底板の中心方向から外縁に向かって流れる空気層を形成することで、第一の吹出口から吹き出した気流と第一の底板の下方空間との静圧差で生じた対流による底板へのミストの付着および外乱によって筐体下面にミストを含む気流が横切ったときに生じる底板へのミストの付着を防止することができる。 By forming an air layer that flows from the center direction of the bottom plate toward the outer edge on the lower surface of the bottom plate over the entire surface of the bottom plate, it is generated by the static pressure difference between the airflow blown out from the first outlet and the space below the first bottom plate. It is possible to prevent the mist from adhering to the bottom plate due to convection and the mist from adhering to the bottom plate that occurs when an air flow containing mist crosses the lower surface of the housing due to disturbance.

第１の発明は、空気の流れを発生させる送風機と、下部に略円形の開口を設けた筐体と前記筐体と前記送風機を連通する第一の吸込口と、前記筐体の内部空間に設けられ、前記開口内部に略同心円上に配置された略円筒状の内円筒部材と、前記内円筒部材に設けられ、前記筐体と前記内円筒部材を連通する第二の吸込口と、前記開口と前記内円筒部材の外周面で形成された環状の第一の吹出口と、前記内円筒部材に設けられた噴霧ノズルと、前記内円筒部材の下部に設けられた略円形の第一の底板と、前記第一の底板に設けられ、前記第一の底板の中心を原点として略円形に開口した底板開口と、前記第一の底板の下方の空間に設けられ、前記底板開口の略同心円上にあり、前記底板開口の直径よりも大きい外径を有する略円形の第二の底板と、前記第一の底板の下面と第二の底板の上面から形成された第二の吹出口とを備えたことを特徴とする。 The first invention relates to a blower that generates an air flow, a housing provided with a substantially circular opening at the bottom, a first suction port that communicates the housing with the blower, and an internal space of the housing. A substantially cylindrical inner cylindrical member provided and arranged substantially concentrically inside the opening, a second suction port provided in the inner cylindrical member and communicating the housing and the inner cylindrical member, and the said An annular first outlet formed on the opening and the outer peripheral surface of the inner cylindrical member, a spray nozzle provided on the inner cylindrical member, and a substantially circular first outlet provided on the lower portion of the inner cylindrical member. A bottom plate, a bottom plate opening provided on the first bottom plate and opened substantially circularly with the center of the first bottom plate as the origin, and a substantially concentric circle of the bottom plate opening provided in the space below the first bottom plate. A substantially circular second bottom plate that is above and has an outer diameter larger than the diameter of the bottom plate opening, and a second outlet formed from the lower surface of the first bottom plate and the upper surface of the second bottom plate. It is characterized by being prepared.

以上の構成において、送風機からの送風は、第二の吸込口と第一の吹出口に分流される。第二の吸込口に流入した空気は第二の底板に衝突して第二の吹出口を通り第一の底板に沿って第一の底板外縁に向かって半径方向に流れる。 In the above configuration, the air blown from the blower is divided into the second suction port and the first air outlet. The air flowing into the second suction port collides with the second bottom plate, passes through the second outlet, and flows radially along the first bottom plate toward the outer edge of the first bottom plate.

これにより、第一の底板全面にわたって第一の底板の中心から外側に向かって流れる空気層が形成される。そのため、第一の吹出口からの吹出気流と第一の底板の下方空間との静圧差から生じる上方に巻き上がるような対流に乗り、内円筒部材下部を浮遊するミストは、第一の底板に付着せずに第一の底板外縁に向かって流される。 As a result, an air layer flowing outward from the center of the first bottom plate is formed over the entire surface of the first bottom plate. Therefore, the mist that floats on the lower part of the inner cylindrical member on the convection that winds up upward due to the static pressure difference between the airflow from the first outlet and the space below the first bottom plate is applied to the first bottom plate. It flows toward the outer edge of the first bottom plate without adhering.

また、第二の底板には第二の吹出口から流出する空気が第二の底板の下面近傍を浮遊するミストを引き込み第一の底板外縁に向かって流すためミストが付着することはない。 Further, since the air flowing out from the second air outlet draws in the mist floating near the lower surface of the second bottom plate and flows toward the outer edge of the first bottom plate, the mist does not adhere to the second bottom plate.

よって、底板全面に渡り、底板の下面に底板の中心方向から外縁に向かって流れる空気
層を形成することで、第一の吹出口から吹き出した気流と第一の底板の下方空間との静圧差から生じる対流による第一の底板へのミストの付着を防止することができる。 Therefore, by forming an air layer that flows from the center direction of the bottom plate toward the outer edge on the lower surface of the bottom plate over the entire surface of the bottom plate, the static pressure difference between the airflow blown out from the first outlet and the space below the first bottom plate. It is possible to prevent the mist from adhering to the first bottom plate due to the convection caused by the air flow.

第２の発明は、第二の吹出口の開口面積が第一の吹出口の開口面積よりも狭いことを特徴とする。 The second invention is characterized in that the opening area of the second outlet is smaller than the opening area of the first outlet.

以上の構成において、冷却装置を横切る様に気流が生じた場合、第一の吹出口から流れるミストを含む空気が第二の底板の下面を流れる。 In the above configuration, when an air flow is generated so as to cross the cooling device, air including mist flowing from the first air outlet flows on the lower surface of the second bottom plate.

この時、第二の吹出口の吹出し面積は小さいため、吹出される気流の速度は増加し、外乱に対する抗力が大きくなる。 At this time, since the blowout area of the second outlet is small, the velocity of the blown airflow increases and the drag against disturbance becomes large.

このため、第一の底板表面を底板中心から外縁へ流れる空気層は外乱に乱されることなく形成される。 Therefore, the air layer flowing from the center of the bottom plate to the outer edge on the surface of the first bottom plate is formed without being disturbed by disturbance.

よって、第一の底板を横切る様に流れる気流に含まれるミストは底板表面に形成された空気層によって底板に付着せずに流れる。 Therefore, the mist contained in the air flow that flows across the first bottom plate flows without adhering to the bottom plate due to the air layer formed on the surface of the bottom plate.

これにより、外乱による気流の流れが強く冷却装置を横切る様に気流が生じる場合でも、底板全面に渡り、底板の下面に底板の中心方向から外縁に向かって流れる空気層を形成することで、底板へのミストの付着を防止することができる。 As a result, even if the airflow is strong due to disturbance and the airflow is generated so as to cross the cooling device, an air layer that flows from the center direction of the bottom plate toward the outer edge is formed on the lower surface of the bottom plate over the entire surface of the bottom plate. It is possible to prevent the mist from adhering to the air.

以下、本発明の実施の形態について、図面を参照しながら説明する。なお、この実施の形態によって本発明が限定されるものではない。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited to this embodiment.

＜実施の形態１＞
図２を参照しながら、本発明の第１の実施の形態における冷却装置について説明する。 <Embodiment 1>
The cooling device according to the first embodiment of the present invention will be described with reference to FIG.

図２は本発明の第１の実施の形態における冷却装置の側面断面図を示すものである。
図２において、冷却装置は、空気の流れを発生させる送風機１１と、下部に略円形の開口を設けた筐体４と、筐体４と送風機１１を連通する第一の吸込口６と、筐体４の内部空間に設けられ、開口内部に略同心円上に配置された略円筒状の内円筒部材５と、内円筒部材５に設けられ、筐体４と内円筒部材５を連通する第二の吸込口７と、開口と内円筒部材５の外周面で形成された環状の第一の吹出口２と、内円筒部材５に設けられた噴霧ノズル１と、内円筒部材５の下部に設けられた略円形の第一の底板８と、第一の底板８に設けられ、第一の底板８の中心を原点として略円形に開口した底板開口１０と、第一の底板８の下方の空間に設けられ、底板開口１０の略同心円上にあり、底板開口１０の直径よりも大きい外径を有する略円形の第二の底板９と、第一の底板８の下面と第二の底板９の上面から形成された第二の吹出口３を備えている。 FIG. 2 shows a side sectional view of the cooling device according to the first embodiment of the present invention.
In FIG. 2, the cooling device includes a blower 11 for generating an air flow, a housing 4 having a substantially circular opening at the bottom, a first suction port 6 for communicating the housing 4 and the blower 11, and a housing. A second inner cylindrical member 5 provided in the internal space of the body 4 and arranged substantially concentrically inside the opening, and a second inner cylindrical member 5 provided in the inner cylindrical member 5 that communicates the housing 4 and the inner cylindrical member 5. Suction port 7, an annular first outlet 2 formed on the opening and the outer peripheral surface of the inner cylindrical member 5, a spray nozzle 1 provided on the inner cylindrical member 5, and a lower portion of the inner cylindrical member 5. A substantially circular first bottom plate 8 and a bottom plate opening 10 provided on the first bottom plate 8 and opened substantially circularly with the center of the first bottom plate 8 as the origin, and a space below the first bottom plate 8. A substantially circular second bottom plate 9 which is provided on a substantially concentric circle of the bottom plate opening 10 and has an outer diameter larger than the diameter of the bottom plate opening 10, and a lower surface of the first bottom plate 8 and a second bottom plate 9. It is provided with a second outlet 3 formed from the upper surface.

以上の構成において、送風機１１からの送風は、第二の吸込口７と第一の吹出口２に分流される。第二の吸込口７に流入した空気は第二の底板９に衝突して第二の吹出口３を通り第一の底板８に沿って第一の底板８外縁に向かって半径方向に流れる。 In the above configuration, the air blown from the blower 11 is divided into the second suction port 7 and the first air outlet 2. The air flowing into the second suction port 7 collides with the second bottom plate 9, passes through the second outlet 3, and flows along the first bottom plate 8 toward the outer edge of the first bottom plate 8 in the radial direction.

これにより、第一の底板８全面にわたって第一の底板８の中心から外側に向かって流れる空気層が形成される。そのため、第一の吹出口２からの吹出気流と第一の底板８の下方空間との静圧差から生じる上方に巻き上がるような対流に乗り、内円筒部材５下部を浮遊するミストは、第一の底板８に付着せずに底板外縁に向かって流される。 As a result, an air layer that flows outward from the center of the first bottom plate 8 is formed over the entire surface of the first bottom plate 8. Therefore, the mist floating in the lower part of the inner cylindrical member 5 on the convection that winds up upward due to the static pressure difference between the airflow from the first outlet 2 and the space below the first bottom plate 8 is the first. It is flown toward the outer edge of the bottom plate without adhering to the bottom plate 8.

また、第二の底板９には第二の吹出口３から流出する空気が第二の底板９の下面近傍を
浮遊するミストを引き込み第一の底板８外縁に向かって流すためミストが付着することはない。 Further, the air flowing out from the second outlet 3 draws the mist floating near the lower surface of the second bottom plate 9 into the second bottom plate 9 and flows toward the outer edge of the first bottom plate 8, so that the mist adheres to the second bottom plate 9. There is no.

よって、底板全面に渡り、底板の下面に底板の中心方向から外縁に向かって流れる空気層を形成することで、第一の吹出口２から吹き出した気流と第一の底板８の下方空間との静圧差から生じる対流による底板へのミストの付着を防止することができる。 Therefore, by forming an air layer flowing from the center direction of the bottom plate toward the outer edge on the lower surface of the bottom plate over the entire surface of the bottom plate, the airflow blown out from the first air outlet 2 and the space below the first bottom plate 8 are formed. It is possible to prevent mist from adhering to the bottom plate due to convection caused by the static pressure difference.

尚、図３の様に第二の底板上面を略円錐形状にすることで、第二の吸込口７から内円筒部材５内部に流入した鉛直下向きに流れる空気は底板上面に形成された略円錐の子午面に沿って流れ、流れに乱れが生じることなく第一の底板８の外縁へ向かう流れとなる。 By forming the upper surface of the second bottom plate into a substantially conical shape as shown in FIG. 3, the air flowing vertically downward from the second suction port 7 into the inner cylindrical member 5 is formed into a substantially conical shape on the upper surface of the bottom plate. It flows along the meridional surface of the first bottom plate 8 and flows toward the outer edge of the first bottom plate 8 without causing turbulence in the flow.

これによって、形成される空気層の強度が増すため、底板へのミストの付着をより防ぐことができる。 As a result, the strength of the formed air layer is increased, so that the mist can be further prevented from adhering to the bottom plate.

尚、図４の様に第一の底板の底板開口１０上部に第二の送風機１２を設け、かつ内円筒部材５の上面に設けられ筐体４を貫通するような第三の吸込口１３を設けることで、第二の吹出口３から流出する空気の量を増加することができるため強固な空気層を形成できる。 As shown in FIG. 4, a second blower 12 is provided above the bottom plate opening 10 of the first bottom plate, and a third suction port 13 is provided on the upper surface of the inner cylindrical member 5 and penetrates the housing 4. By providing the air, the amount of air flowing out from the second air outlet 3 can be increased, so that a strong air layer can be formed.

これによって、より強い外乱に対しても空気層を形成することができ、底板へのミストの付着を防止することができる。 As a result, an air layer can be formed even against stronger disturbances, and mist can be prevented from adhering to the bottom plate.

＜実施の形態２＞
実施の形態２の冷却装置は、第二の吹出口３の開口面積が第一の吹出口２の開口面積よりも狭いことを特徴とする。 <Embodiment 2>
The cooling device of the second embodiment is characterized in that the opening area of the second outlet 3 is smaller than the opening area of the first outlet 2.

以上の構成において、冷却装置を横切る様に気流が生じた場合、第一の吹出口２から流れるミストを含む空気が第二の底板９の下面を流れる。 In the above configuration, when an air flow is generated so as to cross the cooling device, air including mist flowing from the first outlet 2 flows on the lower surface of the second bottom plate 9.

この時、第二の吹出口３の吹出し面積は小さいため、吹出される気流の速度は増加し、外乱に対する抗力が大きくなる。 At this time, since the blowout area of the second outlet 3 is small, the velocity of the blown airflow increases and the drag against disturbance becomes large.

このため、第一の底板８表面を底板中心から外縁へ流れる空気層は外乱に乱されることなく形成される。 Therefore, the air layer flowing from the center of the bottom plate to the outer edge on the surface of the first bottom plate 8 is formed without being disturbed by disturbance.

よって、第一の底板８を横切る様に流れる気流に含まれるミストは底板表面に形成された空気層によって底板に付着せずに流れる。 Therefore, the mist contained in the air flow that flows across the first bottom plate 8 flows without adhering to the bottom plate due to the air layer formed on the surface of the bottom plate.

これにより、外乱による気流の流れが強く冷却装置を横切る様に気流が生じた場合でも、第一の底板８全面に渡り、底板の下面に底板の中心方向から外縁に向かって流れる空気層を形成することで、第一の底板８へのミストの付着を防止することができる。 As a result, even if the airflow is strong due to the disturbance and the airflow is generated so as to cross the cooling device, an air layer is formed on the lower surface of the first bottom plate 8 from the center direction of the bottom plate toward the outer edge. By doing so, it is possible to prevent the mist from adhering to the first bottom plate 8.

以上のように、本発明にかかる冷却装置は、筐体へのミストの付着を防ぐことが可能となるので、工場やサーバー室の閉空間の調湿に用いる噴霧装置にも適用できる。 As described above, since the cooling device according to the present invention can prevent mist from adhering to the housing, it can also be applied to a spraying device used for humidity control in a closed space of a factory or a server room.
