　図１では、冷却装置１は、本体１０１と、脚部２０１と、蓋部３０１とを含む。冷却装置１は、任意の設置面上に設置可能である。設置面は、屋外の地面であってもよいし、屋内の床等であってもよい。以下では、冷却装置１は、設置状態に係る構成が説明される。 In FIG. 1, the cooling device 1 includes a main body 101, legs 201, and a lid 301. The cooling device 1 can be installed on any installation surface. The installation surface may be the outdoor ground, an indoor floor, or the like. In the following, the configuration of the cooling device 1 according to the installation state will be described.
　本体１０１は、鉛直方向を中心軸として延在する円筒状の形態であり、上側及び下側がともに開口する。換言すると、冷却装置１は、本体１０１の中心軸が鉛直方向（重力方向）と略一致するように設置される。本体１０１は、金属製であってもよいし、樹脂製であってもよいし、他の材料により形成されてもよい。本体１０１は、内部に円筒状の空間を形成する。以下、冷却装置１の内部とは、本体１０１の内部（円筒状の空間）に対応するものとする。 The main body 101 has a cylindrical shape extending with the vertical direction as a central axis, and both the upper side and the lower side are open. In other words, the cooling device 1 is installed so that the central axis of the main body 101 substantially coincides with the vertical direction (gravitational direction). The main body 101 may be made of metal, resin, or may be made of another material. The main body 101 forms a cylindrical space inside. Hereinafter, the inside of the cooling device 1 corresponds to the inside of the main body 101 (cylindrical space).
　脚部２０１は、本体１０１の下部に接続される。脚部２０１は、複数個設けられる。例えば、脚部２０１は、本体１０１の周方向に沿って等間隔で複数個設けられる。脚部２０１は、本体１０１を設置面に対して支持する機能を有する。なお、本体１０１は、更に、ワイヤ等の他の手段で補助的に設置面に対して支持されてもよい。 The leg 201 is connected to the bottom of the main body 101. A plurality of legs 201 are provided. For example, the plurality of leg portions 201 are provided at equal intervals along the circumferential direction of the main body 101. The leg portion 201 has a function of supporting the main body 101 with respect to the installation surface. Note that the main body 101 may be supported by the other means such as a wire in a supplementary manner with respect to the installation surface.
　ここで、複数の脚部２０１は、図１に示すように、周方向で互いに離間して設けられる。周方向で隣接する各脚部２０１の間には、隙間があり、当該隙間が空気導入口１１を形成する。 Here, as shown in FIG. 1, the plurality of leg portions 201 are provided so as to be spaced apart from each other in the circumferential direction. There is a gap between the leg portions 201 adjacent to each other in the circumferential direction, and the gap forms the air introduction port 11.
　なお、脚部２０１は、設置面に対する接触面積を増大する部位（例えばフランジ部）を有してよい。これにより、支持安定性を高めることができる。また、脚部２０１は、車輪を有してもよい。この場合、冷却装置１の移動が容易となる。 The leg portion 201 may have a portion (for example, a flange portion) that increases the contact area with the installation surface. Thereby, the support stability can be improved. Further, the leg portion 201 may have wheels. In this case, the cooling device 1 can be easily moved.
　蓋部３０１は、本体１０１の上部の上側に設けられる。蓋部３０１は、野外に冷却装置１が設置される場合に好適であり、雨などを含む異物が冷却装置１の内部に入らないようにする機能（以下、「異物侵入防止機能」と称する）を有する。蓋部３０１は、上面視で、本体１０１の上側の開口の少なくとも一部と重なり、好ましくは、異物侵入防止機能を高めるために、本体１０１の上側の開口の全体と重なる。 The lid 301 is provided on the upper side of the upper part of the main body 101. The lid portion 301 is suitable when the cooling device 1 is installed outdoors, and has a function of preventing foreign matter including rain from entering the inside of the cooling device 1 (hereinafter, referred to as "foreign matter intrusion prevention function"). Have. The lid 301 overlaps at least a part of the upper opening of the main body 101 in a top view, and preferably overlaps the entire upper opening of the main body 101 in order to enhance the foreign substance intrusion prevention function.
　蓋部３０１は、本体１０１の上部に固定されてもよいし、取り外し可能に取り付けられてもよい。 The lid 301 may be fixed to the upper portion of the main body 101 or may be detachably attached.
　蓋部３０１は、本体１０１の上部との間に隙間が形成される態様で、本体１０１に取り付けられ、当該隙間が空気排出口１２を形成する。なお、蓋部３０１は、空気排出口１２の一部を形成する穴を有してもよい。 The lid 301 is attached to the main body 101 so that a gap is formed between the lid 301 and the upper portion of the main body 101, and the gap forms the air outlet 12. The lid 301 may have a hole forming a part of the air outlet 12.
　なお、屋内に設置されることが予定される冷却装置１の場合等は、蓋部３０１は省略されてもよい。 Note that the lid 301 may be omitted in the case of the cooling device 1 that is planned to be installed indoors.
　図２は、冷却装置１の内部における冷却原理の説明図であり、冷却装置１の本体１０１の中心軸を通る概略断面図である。図２には、説明用に、空気の流れが矢印Ｒ１～Ｒ３で模式的に示される。 FIG. 2 is an explanatory view of the cooling principle inside the cooling device 1, and is a schematic cross-sectional view passing through the central axis of the main body 101 of the cooling device 1. In FIG. 2, the flow of air is schematically shown by arrows R1 to R3 for explanation.
　図２には、冷却装置１の内部に、冷却対象物８０が配置されている。図２に示す例では、冷却対象物８０は、冷却装置１と同じ設置面Ｇ上に設置されたテーブル７０上に載置されている。なお、テーブル７０は、冷却装置１とは別体であるが、変形例では、冷却対象物８０を載置可能な部材が冷却装置１と一体的に設けられてもよい。なお、テーブル７０の上面は、好ましくは、通風性のある構成であり、例えばメッシュ状の材料により形成されてよい。なお、冷却対象物８０は、テーブル７０上に載置される以外にも、蓋部３０１から吊り下げられてもよいし、内部に延在するネット（図６のネット７２）上に載置されてもよい。 In FIG. 2, a cooling target 80 is arranged inside the cooling device 1. In the example shown in FIG. 2, the cooling target object 80 is placed on the table 70 installed on the same installation surface G as the cooling device 1. Note that the table 70 is a separate body from the cooling device 1, but in a modification, a member on which the cooling target object 80 can be placed may be integrally provided with the cooling device 1. The upper surface of the table 70 preferably has a ventilation structure, and may be formed of, for example, a mesh material. The object 80 to be cooled may be hung from the lid 301 instead of being placed on the table 70, or placed on a net (net 72 in FIG. 6) extending inside. May be.
　冷却装置１の内部に、外気よりも高温な冷却対象物８０を配置した場合は、図２に示すように、煙突効果により上昇気流が発生する。すなわち、外気は、冷却装置１の内部に空気導入口１１から導入され（矢印Ｒ１参照）、冷却装置１の内部を上昇し（矢印Ｒ２参照）、空気排出口１２から冷却装置１の外部へと排出される（矢印Ｒ３参照）。このようにして発生する気流によって冷却対象物８０を効率的に冷却できる。 When a cooling target 80 having a temperature higher than that of the outside air is arranged inside the cooling device 1, ascending air current is generated by the stack effect as shown in FIG. That is, the outside air is introduced into the cooling device 1 from the air introduction port 11 (see arrow R1), rises inside the cooling device 1 (see arrow R2), and goes from the air discharge port 12 to the outside of the cooling device 1. It is discharged (see arrow R3). The cooling target 80 can be efficiently cooled by the airflow generated in this way.
　本実施例によれば、上述のように、煙突効果を利用して、比較的簡易な構成で効率的に冷却対象物を冷却することが可能となる。すなわち、冷却装置１は、上述のように、本体１０１に脚部２０１を設けた比較的簡易な構成であり、電力を必要とすることなく動作できる。従って、電気が通っていない地域等でも利用できる。また、煙突効果を利用することで、内部の冷却対象物を効率的に冷却できる。また、脚部２０１を有することで、屋外でも安定して設置でき、空気導入口１１を地表付近に設定しやすくなる。これにより、地表付近の比較的低い温度の空気を空気導入口１１から導入しやすくなり、冷却効率を高めることができる。 According to the present embodiment, as described above, it is possible to efficiently cool the object to be cooled with a relatively simple structure by utilizing the stack effect. That is, the cooling device 1 has a relatively simple configuration in which the legs 201 are provided on the main body 101 as described above, and can operate without requiring electric power. Therefore, it can be used in areas where electricity is not available. Further, by utilizing the chimney effect, the object to be cooled inside can be efficiently cooled. Further, by having the leg portion 201, the leg portion 201 can be stably installed outdoors, and the air introduction port 11 can be easily set near the ground surface. As a result, it becomes easier to introduce the air having a relatively low temperature near the surface of the earth from the air introduction port 11, and the cooling efficiency can be improved.
　なお、本実施例では、本体１０１は、一定の内径であるが、これに限られない。例えば本体１０１は、上に向かうほど内径が小さくなる円筒状の形態であってもよい。また、本体１０１は、円筒状に限られず、上面視の外形が矩形や多角形である筒状の形態であってもよい。 In this embodiment, the main body 101 has a constant inner diameter, but it is not limited to this. For example, the main body 101 may have a cylindrical shape whose inner diameter becomes smaller as it goes upward. Further, the main body 101 is not limited to a cylindrical shape, and may have a tubular shape whose outer shape in a top view is a rectangle or a polygon.
　また、本実施例において、本体１０１は、窓やドア等が設けられていないが、窓やドア等の付属部材が設けられてもよい。 Further, in the present embodiment, the main body 101 is not provided with windows or doors, but may be provided with additional members such as windows or doors.
　［実施例２］
　実施例２による冷却装置２は、上述した実施例１による冷却装置１に対して、本体１０１が本体１０２で置換された点が異なる。実施例２に関して、上述した実施例１と同様であってよい構成要素については、同一の参照符号を付して説明を省略する場合がある。 [Example 2]
The cooling device 2 according to the second embodiment is different from the cooling device 1 according to the above-described first embodiment in that the main body 101 is replaced by the main body 102. With regard to the second embodiment, constituent elements that may be similar to those of the first embodiment described above may be denoted by the same reference numerals, and description thereof may be omitted.
　図３は、実施例２による冷却装置２を概略的に示す斜視図である。なお、図３には、上述した実施例１による冷却装置１が備える蓋部３０１が図示されていない。本実施例において、蓋部３０１は、同様に設けられてもよいし、設けられなくてもよい。 FIG. 3 is a perspective view schematically showing the cooling device 2 according to the second embodiment. Note that FIG. 3 does not show the lid portion 301 included in the cooling device 1 according to the first embodiment described above. In the present embodiment, the lid portion 301 may be similarly provided or may not be provided.
　本体１０２は、上半体１０２ａと、下半体１０２ｂと含み、下半体１０２ｂは上半体１０２ａよりも内径が大きい。すなわち、本体１０２は、下部の内径が上部の内径よりも大きい。これにより、下半体１０２ｂの内径が上半体１０２ａの内径以下の場合に比べて、空気導入口１１からの空気の導入量を増加でき、冷却効率を高めることができる。 The main body 102 includes an upper half body 102a and a lower half body 102b, and the lower half body 102b has a larger inner diameter than the upper half body 102a. That is, the main body 102 has a lower inner diameter larger than an upper inner diameter. As a result, compared with the case where the inner diameter of the lower half body 102b is less than or equal to the inner diameter of the upper half body 102a, the amount of air introduced from the air introduction port 11 can be increased, and the cooling efficiency can be improved.
　本実施例によれば、上述した実施例１と同様の効果が奏される。また、本実施例によれば、拡径した下半体１０２ｂを有することで、空気導入口１１からの空気の導入量を増加でき、冷却効率を高めることができる。 According to this embodiment, the same effect as that of the above-described Embodiment 1 can be obtained. Further, according to the present embodiment, by having the expanded lower half 102b, the amount of air introduced from the air inlet 11 can be increased and the cooling efficiency can be increased.
　なお、上述した実施例１において説明した各種の変形例については、本実施例に対しても適用可能である。 The various modified examples described in the above-described first embodiment can be applied to this embodiment.
　［実施例３］
　実施例３による冷却装置３は、上述した実施例１による冷却装置１に対して、本体１０１が本体１０３で置換された点が異なる。実施例３に関して、上述した実施例１と同様であってよい構成要素については、同一の参照符号を付して説明を省略する場合がある。 [Example 3]
The cooling device 3 according to the third embodiment is different from the cooling device 1 according to the first embodiment described above in that the main body 101 is replaced by the main body 103. With regard to the third embodiment, constituent elements that may be the same as those in the above-described first embodiment may be assigned the same reference numerals and may not be described.
　図４は、実施例３による冷却装置３を概略的に示す斜視図である。なお、図４には、上述した実施例１による冷却装置１が備える蓋部３０１が図示されていない。本実施例において、蓋部３０１は、同様に設けられてもよいし、設けられなくてもよい。 FIG. 4 is a perspective view schematically showing the cooling device 3 according to the third embodiment. Note that FIG. 4 does not show the lid portion 301 included in the cooling device 1 according to the first embodiment described above. In the present embodiment, the lid portion 301 may be similarly provided or may not be provided.
　本体１０３は、上半体１０３ａと、下半体１０３ｂと含み、下半体１０３ｂは上半体１０２ａよりも内径が大きい。すなわち、本体１０３は、下部の内径が上部の内径よりも大きい。これにより、下半体１０２ｂの内径が上半体１０２ａの内径以下の場合に比べて、空気導入口１１からの空気の導入量を増加でき、冷却効率を高めることができる。ただし、変形例では、下半体１０２ｂの内径が上半体１０２ａの内径以下であってもよい。 The main body 103 includes an upper half body 103a and a lower half body 103b, and the lower half body 103b has a larger inner diameter than the upper half body 102a. That is, in the main body 103, the inner diameter of the lower portion is larger than the inner diameter of the upper portion. As a result, compared with the case where the inner diameter of the lower half body 102b is less than or equal to the inner diameter of the upper half body 102a, the amount of air introduced from the air introduction port 11 can be increased, and the cooling efficiency can be improved. However, in a modification, the inner diameter of the lower half body 102b may be equal to or smaller than the inner diameter of the upper half body 102a.
　本実施例では、下半体１０３ｂには、径方向に貫通する穴１０３１が形成される。穴１０３１は、空気導入口１１の一部を形成する。穴１０３１は、周方向に沿って複数個設けられてもよい。なお、図４では、穴１０３１は、周方向に沿って一列に設けられるが、穴１０３１は、上下方向にオフセットした複数列に設けられてもよい。 In this embodiment, a hole 1031 penetrating in the radial direction is formed in the lower half body 103b. The hole 1031 forms a part of the air introduction port 11. A plurality of holes 1031 may be provided along the circumferential direction. In FIG. 4, the holes 1031 are provided in one row along the circumferential direction, but the holes 1031 may be provided in a plurality of rows offset in the vertical direction.
　本実施例によれば、上述した実施例１と同様の効果が奏される。また、本実施例によれば、下半体１０３ｂに穴１０３１を有することで、空気導入口１１からの空気の導入量を増加でき、冷却効率を高めることができる。 According to this embodiment, the same effect as that of the above-described Embodiment 1 can be obtained. Further, according to the present embodiment, since the lower half body 103b has the hole 1031, the amount of air introduced from the air introduction port 11 can be increased and the cooling efficiency can be improved.
　なお、上述した実施例１において説明した各種の変形例については、本実施例に対しても適用可能である。 The various modified examples described in the above-described first embodiment can be applied to this embodiment.
　［実施例４］
　実施例４による冷却装置４は、上述した実施例１による冷却装置１に対して、液体噴出部４０を更に含む点が異なる。実施例４に関して、上述した実施例１と同様であってよい構成要素については、同一の参照符号を付して説明を省略する場合がある。 [Example 4]
The cooling device 4 according to the fourth embodiment is different from the cooling device 1 according to the above-described first embodiment in that the cooling device 4 further includes a liquid ejection portion 40. With regard to the fourth embodiment, constituent elements that may be the same as those in the above-described first embodiment may be denoted by the same reference numerals, and description thereof may be omitted.
　図５は、実施例４による冷却装置４を概略的に示す断面図である。 FIG. 5 is a sectional view schematically showing the cooling device 4 according to the fourth embodiment.
　冷却装置４は、冷却対象物８０に向けて液体を噴霧する液体噴出部４０を更に含む。液体噴出部４０は、図５に示すように、冷却対象物８０の上方に設けられ、下向きに液体を噴霧する。液体は、任意であるが、例えば、入手が容易な水である。 The cooling device 4 further includes a liquid ejection unit 40 that sprays a liquid toward the cooling target 80. As shown in FIG. 5, the liquid ejecting unit 40 is provided above the cooling target 80 and sprays the liquid downward. The liquid is optional, but is, for example, readily available water.
　図５では、液体噴出部４０は、本体１０４の内部まで延在する管路部材４１により形成され、冷却対象物８０の上方付近に噴霧穴４１ａを多数備える。なお、本体１０４は、上述した実施例１による本体１０１に対して、管路部材４１が通る点が異なる。管路部材４１は、図５に示すように、本体１０４の外部でホース４２に接続可能である。ホース４２は、例えば水道水の蛇口等に接続される。この場合、水道水を利用して、液体噴出部４０から水を噴霧できる。なお、変形例では、管路部材４１が水源に接続されてもよい。また、本実施例では、電気を利用しないためにポンプは利用しないが、ポンプ等により水が圧送されてもよい。 In FIG. 5, the liquid ejecting portion 40 is formed by the conduit member 41 extending to the inside of the main body 104, and has a large number of spray holes 41 a near the upper side of the cooling target 80. The main body 104 differs from the main body 101 according to the first embodiment described above in that the conduit member 41 passes through. As shown in FIG. 5, the conduit member 41 can be connected to the hose 42 outside the main body 104. The hose 42 is connected to, for example, a tap water tap. In this case, tap water can be used to spray water from the liquid ejecting section 40. In addition, in the modification, the conduit member 41 may be connected to a water source. Further, in the present embodiment, the pump is not used because electricity is not used, but water may be pumped by the pump or the like.
　噴霧穴４１ａから水が噴霧されると、気化熱により冷却対象物８０及びその周辺の熱が奪われるので、冷却対象物８０が冷却される。本実施例では、上述のように煙突効果により上昇気流が生じる。このため、冷却対象物８０により暖められた空気によって噴霧穴４１ａからの水が気化しやすくなり、気化熱の作用を効率的に利用できる。 When water is sprayed from the spray holes 41a, the heat of vaporization removes the heat of the cooling target 80 and its surroundings, so the cooling target 80 is cooled. In this embodiment, ascending airflow is generated by the chimney effect as described above. For this reason, the water warmed by the object to be cooled 80 easily vaporizes the water from the spray hole 41a, and the action of vaporization heat can be efficiently utilized.
　本実施例によれば、上述した実施例１と同様の効果が奏される。また、本実施例によれば、液体噴出部４０を有することで、気化熱を利用して冷却効率を高めることができる。 According to this embodiment, the same effect as that of the above-described Embodiment 1 can be obtained. Further, according to the present embodiment, since the liquid ejection portion 40 is provided, it is possible to enhance the cooling efficiency by utilizing the heat of vaporization.
　なお、上述した実施例１において説明した各種の変形例については、本実施例に対しても適用可能である。 The various modified examples described in the above-described first embodiment can be applied to this embodiment.

With regard to the fifth embodiment, components that may be the same as those of the first embodiment described above may be assigned the same reference numerals, and description thereof may be omitted.
　図６は、実施例５による冷却装置５を概略的に示す断面図である。 FIG. 6 is a sectional view schematically showing the cooling device 5 according to the fifth embodiment.
　冷却装置５は、本体１０５の外側から本体１０５の内部に連通する液体供給部５０を備える。なお、本体１０５は、上述した実施例１による本体１０１に対して、液体供給部５０の管路部５１が通る点が異なる。 The cooling device 5 includes a liquid supply unit 50 that communicates with the inside of the main body 105 from the outside of the main body 105. The main body 105 is different from the main body 101 according to the first embodiment described above in that the conduit portion 51 of the liquid supply unit 50 passes through.
　液体供給部５０は、本体１０５の内部に配置可能な、液体を浸潤可能な材料５０１に、液体を供給可能である。液体は、任意であるが、例えば、入手が容易な水である。材料５０１は、布材や、繊維材料等であってよい。材料５０１は、毛細管現象によって液体供給部５０からの水を吸い取る機能を有する。材料５０１は、冷却対象物の近傍に設けられる。図６では、材料５０１は、冷却対象物８０の下方に設けられる。なお、図６では、冷却対象物８０は、ネット７２上に載置されているが、他の方法で設けられてもよい。ネット７２は、冷却装置５の内部の周面等に端部が引っ掛けられることで張れてもよい。 The liquid supply unit 50 can supply the liquid to the liquid-infiltrating material 501 that can be arranged inside the main body 105. The liquid is optional, but is, for example, readily available water. The material 501 may be a cloth material, a fiber material, or the like. The material 501 has a function of absorbing water from the liquid supply unit 50 by a capillary phenomenon. The material 501 is provided near the object to be cooled. In FIG. 6, the material 501 is provided below the cooling target object 80. Although the cooling object 80 is placed on the net 72 in FIG. 6, it may be provided by another method. The net 72 may be stretched by hooking the end portion on the inner peripheral surface of the cooling device 5 or the like.
　図６では、液体供給部５０は、管路部５１と、容器部５２とを含む。管路部５１は、材料５０１に一端が接続され、容器部５２に他端が接続される。容器部５２は、本体１０５の外側に設けられ、上部が開口する。容器部５２は、液体を貯留する。 In FIG. 6, the liquid supply unit 50 includes a conduit portion 51 and a container portion 52. The conduit portion 51 has one end connected to the material 501 and the other end connected to the container portion 52. The container portion 52 is provided outside the main body 105 and has an upper opening. The container portion 52 stores the liquid.
　液体供給部５０は、１つの冷却装置５に対して複数個設けられてもよい。例えば、液体供給部５０は、本体１０５の周方向に沿って複数個設けられてもよい。 A plurality of liquid supply units 50 may be provided for one cooling device 5. For example, a plurality of liquid supply units 50 may be provided along the circumferential direction of the main body 105.
　本実施例によれば、上述した実施例１と同様の効果が奏される。また、本実施例では、上述のように煙突効果により上昇気流が生じる。このため、上述のように材料５０１で液体が蒸発（気化）しやすくなる。容器部５２に液体が貯留している状態では、材料５０１に液体が供給され続けるので、常に気化熱による冷却を実現できる。 According to this embodiment, the same effect as that of the above-described Embodiment 1 can be obtained. In addition, in the present embodiment, ascending airflow occurs due to the chimney effect as described above. Therefore, as described above, the material 501 easily evaporates (vaporizes) the liquid. In the state where the liquid is stored in the container portion 52, the liquid is continuously supplied to the material 501, so that the cooling can be always realized by the heat of vaporization.
　なお、本実施例において、管路部５１には、上述した実施例４のようなホース４２を介して水源（例えば水道水の蛇口）が接続されてもよい。 In the present embodiment, the water source (for example, tap water tap) may be connected to the conduit portion 51 via the hose 42 as in the above-described fourth embodiment.

　実施例６による冷却装置６は、上述した実施例１による冷却装置１に対して、空気導入管９０を更に含む点が異なる。実施例６に関して、上述した実施例１と同様であってよい構成要素については、同一の参照符号を付して説明を省略する場合がある。 [Example 6]
The cooling device 6 according to the sixth embodiment is different from the cooling device 1 according to the above-described first embodiment in that an air introduction pipe 90 is further included. With regard to the sixth embodiment, the constituent elements that may be the same as those of the first embodiment described above will be denoted by the same reference numerals, and description thereof may be omitted.
　図７は、実施例６による冷却装置６を概略的に示す斜視図である。 FIG. 7 is a perspective view schematically showing the cooling device 6 according to the sixth embodiment.
　冷却装置６は、本体１０６に螺旋状に接続される複数の空気導入管９０を含む。なお、本体１０６は、上述した実施例１による本体１０１に対して、複数の空気導入管９０が接続される点が異なる。また、本体１０６は、上述した実施例１による本体１０１に対して、比較的背が高く、上方に向かうほど小径になっているが、背の高さ等は本体１０１と同様であってもよい。 The cooling device 6 includes a plurality of air introduction pipes 90 spirally connected to the main body 106. The main body 106 is different from the main body 101 according to the first embodiment described above in that a plurality of air introduction tubes 90 are connected. Further, the main body 106 is relatively taller than the main body 101 according to the above-described first embodiment and has a smaller diameter toward the upper side, but the height of the back and the like may be the same as that of the main body 101. ..
　複数の空気導入管９０は、煙突効果により冷却装置６の内部に生じる上昇気流に対して回転を付与する機能を有する。すなわち、複数の空気導入管９０から冷却装置６の内部には外気が導入される。複数の空気導入管９０は螺旋状に本体１０６に接続されているので、空気導入口１１から導入された空気は、本体１０６の内部に周方向に回転しながら上昇する。 The plurality of air introduction pipes 90 have a function of imparting rotation to the rising airflow generated inside the cooling device 6 due to the chimney effect. That is, the outside air is introduced into the cooling device 6 from the plurality of air introduction pipes 90. Since the plurality of air introduction pipes 90 are spirally connected to the main body 106, the air introduced from the air introduction port 11 rises inside the main body 106 while rotating in the circumferential direction.
　本実施例によれば、上述した実施例１と同様の効果が奏される。また、本実施例では、上述のように煙突効果による上昇気流に回転成分を付与できる。これにより、冷却対象物８０の全体が均一的に冷却されることを期待できる。 According to this embodiment, the same effect as that of the above-described Embodiment 1 can be obtained. Further, in this embodiment, as described above, the rotation component can be added to the ascending airflow due to the stack effect.

　図８に示す例では、図８に矢印Ｒ１０～Ｒ１２で模式的に示すように、煙突効果により、空気導入口１１から内部に流入した空気（矢印Ｒ１０参照）は、上昇し（矢印Ｒ１１参照）、空気排出口１２Ａから斜め下向きに排出される（矢印Ｒ１２参照）。 As shown in FIG. 8, the upper portion of the main body 101A is bent so that the air outlet 12A is opened obliquely downward. In this case, since the air outlet 12A is opened obliquely downward, it is possible to prevent foreign matter including rain from entering the inside of the cooling device. In this case, the lid portion 301 described in the first embodiment is not necessary and may be omitted.
In the example shown in FIG. 8, as schematically shown by arrows R10 to R12 in FIG. 8, the air (see arrow R10) flowing in from the air introduction port 11 rises (see arrow R11) due to the stack effect. , Is discharged obliquely downward from the air discharge port 12A (see arrow R12).
　なお、図８では、空気排出口１２Ａが斜め下向きに開口するが、空気排出口１２Ａが水平方向に開口してもよい。この場合も、雨などを含む異物が冷却装置の内部に入らないようにすることができる。 In FIG. 8, the air outlet 12A opens obliquely downward, but the air outlet 12A may open horizontally. Also in this case, it is possible to prevent foreign matter including rain from entering the inside of the cooling device.
　以上、各実施例について詳述したが、特定の実施例に限定されるものではなく、特許請求の範囲に記載された範囲内において、種々の変形及び変更が可能である。また、前述した実施例の構成要素を全部又は複数を組み合わせることも可能である。 Although the respective embodiments have been described in detail above, the present invention is not limited to the specific embodiments, and various modifications and changes can be made within the scope of the claims. Further, it is possible to combine all or a plurality of the constituent elements of the above-described embodiments.
