Abstract

[Problem] The present invention addresses the problem of providing a fabric product cooling device which uses a hollow fiber membrane, and with which it is easy to eliminate clogging of the hollow fiber membrane. [Solution] The problem is solved by a fabric product cooling device comprising a hollow fiber membrane having one end opening and another end opening, and having fine pores in a wall surface. The hollow fiber membrane is provided with: a water first supply part for supplying water to the hollow fiber membrane; and a water absorbing part that has a band body which absorbs and diffuses water exuding from the fine pores in the wall surface of the hollow fiber membrane. By making the fine pores in the wall surface of the hollow fiber membrane serve as the water first supply part, it is possible to convert water supplied to the inside of the hollow fiber membrane into dust-free water. Furthermore, the water inside the hollow fiber membrane can be pushed out from the inside of the hollow fiber membrane through the fine pores in the wall surface, which makes it possible to eliminate clogging of the fine pores in the wall surface of the hollow fiber membrane.

　布製製品冷却装置は、布製製品を冷却する。また、布製製品冷却装置は装置周辺の空気も冷却する。装置周辺の空気を冷却することにより、装置周辺の人や物を冷却する。出願に係る冷却装置が冷却する対象の布製品には、衣類、ソファー、寝具、クッション、自動車の内装が含まれる。 The fabric product cooling device cools the fabric product. The fabric cooling system also cools the air around the system. By cooling the air around the device, people and things around the device are cooled. Fabric products to be cooled by the cooling device according to the application include clothing, sofas, bedding, cushions, and automobile interiors.
　布製製品冷却装置は、中空糸膜と第一貯水部を備える。中空糸膜は一端開口と他端開口を備え壁面に微細孔を備える。 The fabric product cooling device has a hollow fiber membrane and a first water reservoir. The hollow fiber membrane has an opening at one end and an opening at the other end, and has micropores on the wall surface.
　また、中空糸膜は水の第一供給部と水の被吸収部を備える。 In addition, the hollow fiber membrane has a first water supply portion and a water absorption portion.
　水の第一供給部は、中空糸膜の一端開口と他端開口の間に存する、中空糸膜の一部分である。水の第一供給部は中空糸膜に水を供給する。水の第一供給部は、中空糸膜の、一端と他端の間の部分であればどこでもよい。一端と他端の間の部分は中空糸膜であるので管状の形体で成り、壁面には微細孔を備える。水の第一供給部は第一貯水部に存し、中空糸膜の壁の微細孔から中空糸膜内に入る。中空糸膜の壁の微細孔の直径よりも小さなゴミは中空糸膜に入ることなく第一貯水部に残る。 The first water supply part is a part of the hollow fiber membrane that exists between one end opening and the other end opening of the hollow fiber membrane. A first supply of water supplies water to the hollow fiber membranes. The first supply of water may be anywhere between one end and the other end of the hollow fiber membrane. Since the portion between one end and the other end is a hollow fiber membrane, it has a tubular shape, and the wall surface is provided with micropores. A first supply of water resides in the first reservoir and enters the hollow fiber membrane through the pores in the wall of the hollow fiber membrane. Debris smaller than the diameter of the micropores in the wall of the hollow fiber membrane does not enter the hollow fiber membrane and remains in the first reservoir.
　水の被吸収部は水の第一供給部と一端開口の間部分の中空糸膜及び／又は水の第一供給部と他端開口の間部分の中空糸膜である。水の被吸収部は中空糸膜の壁面の微細孔から滲出する水を吸収し拡散する帯体を備える。冷却装置は、中空糸膜から滲出する水の気化熱を使用して周囲の空気を冷やす。水の被吸収部において吸水拡散性の高い素材で成る帯体が中空糸膜と接しており、帯体が中空糸膜から滲出する水を短時間で吸水拡散し、周囲の空気の冷却とを助ける。 The water absorbing portion is the hollow fiber membrane between the first water supply portion and the one end opening and/or the hollow fiber membrane between the first water supply portion and the other end opening. The water-absorbing portion has a strip that absorbs and diffuses water exuding from the micropores on the wall surface of the hollow fiber membrane. Coolers use the heat of vaporization of water exuding from the hollow fiber membranes to cool the surrounding air. A band made of a material with high water absorption and diffusion property is in contact with the hollow fiber membrane in the water absorbing part, and the band quickly absorbs and diffuses the water exuded from the hollow fiber membrane, thereby cooling the surrounding air. help.
　第一貯水部には水の第一供給部に水を供給する水が蓄えられており、水の第一供給部すなわち中空糸膜の一端開口と他端開口の間に存する、中空糸膜の一部分は、第一貯水部に配置されている。 Water for supplying water to the first water supply part is stored in the first water storage part. A portion is located in the first reservoir.
　中空糸膜は、さらに水の第二供給部を備えてもよい。水の第二供給部は中空糸膜の一端開口と他端開口である。第二貯水部には、水の第二供給部に供給する水が蓄えられており、水の第二供給部すなわち中空糸膜の一端開口と他端開口は第二貯水部に配置されている。水の第二供給部は、中空糸膜の一端開口と他端開口である。水の第二供給部では、水は、中空糸膜の一端開口と他端開口を介して中空糸膜内に入る。水の第二供給部を設けることによって他端開口と一端開口から出た水を貯めておくことができる。また、水の第二供給部から水の第一供給部に向けて水を押し出すことにより、水の第一供給部である中空糸膜の壁面の微細孔の詰まりを解消することができる。 The hollow fiber membrane may further include a second supply of water. The second supply of water is the opening at one end and the opening at the other end of the hollow fiber membrane. The second water reservoir stores water to be supplied to the second water supply part, and the second water supply part, that is, the one end opening and the other end opening of the hollow fiber membrane are arranged in the second water storage part. . The second supply of water is the opening at one end and the opening at the other end of the hollow fiber membrane. In the second supply of water, water enters the hollow fiber membrane through one end opening and the other end opening of the hollow fiber membrane. By providing a second supply of water, water from the other end opening and the one end opening can be stored. Further, by pushing out water from the second water supply portion toward the first water supply portion, clogging of the micropores on the wall surface of the hollow fiber membrane, which is the first water supply portion, can be eliminated.
　水の第二供給部から中空糸膜内に入った水は、中空糸膜内を通過して水の第一供給部に到達し、水の第一供給部である微細孔から第一貯水部に向けて流れ出る。その際、水の第一供給部の微細孔に詰まった微細なゴミが、第一貯水部に向けて放出される。 The water entering the hollow fiber membrane from the second water supply part passes through the hollow fiber membrane and reaches the first water supply part, and passes through the micropores that are the first water supply part to the first water storage part. flow towards. At that time, fine dust clogged in the fine holes of the first water supply section is discharged toward the first water reservoir.
　水の第一供給部として機能した一端開口と他端開口の間に存する中空糸膜の一部分は、中空糸膜の微細孔を塞ぐもの（例えば微細なゴミ）を水の圧力で押し出すためにも用いられてもよい。中空糸膜内の水を、壁面の微細孔を通じて中空糸膜の外部に押し出すことにより、微細孔を塞ぐものが外部に押し出される。その結果、中空糸膜のいわゆる目詰まりを解消できる。 A part of the hollow fiber membrane existing between the one end opening and the other end opening which functioned as the first supply part of water is also used to push out what clogs the micropores of the hollow fiber membrane (for example, fine dust) by the pressure of the water. may be used. By pushing out the water in the hollow fiber membrane to the outside of the hollow fiber membrane through the micropores in the wall surface, the substances blocking the micropores are pushed out. As a result, so-called clogging of the hollow fiber membrane can be eliminated.
　第一貯水部と第二貯水部の水は、両貯水部を往復する過程で、中空糸膜の壁の微細孔から滲出するため、冷却を継続するためには、水の補充が必要である。第一タンクはそのために用いられる。第一タンクは、水の注入口を備え、外部から水の補充ができる。第一タンクはフィルターを備え、第一貯水部に中空糸膜の内径よりも大きな粒子が流入することを防いでいる。 The water in the first water reservoir and the second water reservoir oozes out of the micropores in the walls of the hollow fiber membranes in the process of reciprocating between the two water reservoirs, so water must be replenished to continue cooling. . The first tank is used for that purpose. The first tank has a water inlet and can be replenished with water from the outside. The first tank is equipped with a filter to prevent particles larger than the inner diameter of the hollow fiber membrane from flowing into the first reservoir.
　第一貯水部に第一タンクを設けたのとほぼ同様の要請により、第二貯水部に第二タンクを設ける。 A second tank will be installed in the second reservoir due to almost the same request as the first tank in the first reservoir.
　第一貯水部に水を供給する第一タンクを設け、第一タンクを第二貯水部ともつながるようにすることにより、水の循環ができる。すなわち、水は、第一タンク、第一貯水部、水の第一供給部、水の被供給部、水の第二供給部、第二貯水部、第一タンク、の順に中空糸膜内を介して巡る。このような構成にすると、ポンプが一つであるにも関わらず、高い冷却効果を維持できる。冷却装置を取り付ける製品の対象が大きい場合には、大きなタンクを用いることにより対応できる。 By providing a first tank that supplies water to the first water storage section and connecting the first tank to the second water storage section, water can be circulated. That is, water flows through the hollow fiber membrane in the order of the first tank, the first water storage section, the first water supply section, the water receiving section, the second water supply section, the second water storage section, and the first tank. go through. With such a configuration, a high cooling effect can be maintained even though there is only one pump. If the target of the product to which the cooling device is attached is large, it can be handled by using a large tank.

　本発明の好適な実施形態について、図面を参照し説明する。 A preferred embodiment of the present invention will be described with reference to the drawings.
　図１と図２を参照して実施例1を説明する。 The first embodiment will be described with reference to FIGS. 1 and 2.
　図１に示す通り、クリーンユニット１は、帯体２に取り付けた中空糸膜３を備える。 As shown in FIG. 1, the clean unit 1 is equipped with hollow fiber membranes 3 attached to a strip 2.
　中空糸膜３は、一端３ｂと、他端３ｃと、中央付近（３ａ）において、帯体２に取り付けられておらず、中空糸膜３は露出している。中空糸膜３は、一端３ｂと中央付近（３ａ）の間の箇所、及び他端３ｃと中央付近（３ａ）の間の箇所にあっては帯体２に取り付けられている。中空糸膜３は、帯体２に取り付けられている個所にあっては露出しておらず帯体２の幅方向中央部において帯体を構成する素材にくるまれている。 The hollow fiber membranes 3 are not attached to the strip 2 at one end 3b, the other end 3c, and the vicinity of the center (3a), and the hollow fiber membranes 3 are exposed. The hollow fiber membranes 3 are attached to the strip 2 at a location between one end 3b and the center (3a) and at a location between the other end 3c and the center (3a). The hollow fiber membranes 3 are not exposed where they are attached to the band 2, but are wrapped in the material forming the band at the central portion in the width direction of the band 2. As shown in FIG.
　中空糸膜３のうち、帯体２に取り付けられておらず露出している個所は、水中に置かれる。すなわち、中空糸膜の一端３ｂと他端３ｃはリザーブタンク１５に配置される。中空糸膜３の中央付近（３ａ）は浄水フィルター１０に配置される。 A portion of the hollow fiber membrane 3 that is not attached to the band 2 and is exposed is placed in water. That is, one end 3b and the other end 3c of the hollow fiber membrane are arranged in the reserve tank 15. As shown in FIG. The vicinity of the center ( 3 a ) of the hollow fiber membrane 3 is arranged in the water purification filter 10 .
　中空糸膜３のうち、帯体２に取り付けられた箇所、すなわち帯体を構成する素材にくるまれている箇所が、周囲を冷却する機能を果たす。帯体２は、幅方向中央部において長さ方向に延びる空所を備えている。中空糸膜３はその空所内に入れ込まれている。中空糸膜３は、帯体の空所内において、帯体の長さ方向に、帯体を構成する素材にくるまれるようにして延びている。帯体２を構成する素材にくるまれることにより、中空糸膜３から滲み出る水は帯体２に吸水されやすい。中空糸膜は直径０．３ｍから２ｍｍであり、外壁膜に直径１０ｎｍから１，５００ｎｍの微細孔を備える。中空糸膜は、吸水しやすく、かつ拡散しやすい素材で成る。中空糸膜は、例えば、ナイロン、ポリエステル、ポリフッ化ビニリデン、ポリスルホン、シリコン、フッ素系樹脂、ポリ塩化ビニル、等で成る。 The portion of the hollow fiber membrane 3 attached to the band 2, that is, the portion wrapped in the material forming the band functions to cool the surroundings. The strip 2 has a longitudinally extending cavity in its widthwise central portion. A hollow fiber membrane 3 is placed in the cavity. The hollow fiber membranes 3 extend in the lengthwise direction of the strip in the hollow space of the strip so as to be wrapped in the material forming the strip. Since the band 2 is wrapped in the material forming the band 2 , the water exuding from the hollow fiber membranes 3 is easily absorbed by the band 2 . The hollow fiber membrane has a diameter of 0.3 m to 2 mm, and the outer membrane has fine pores with a diameter of 10 nm to 1,500 nm. The hollow fiber membrane is made of a material that easily absorbs and diffuses water. Hollow fiber membranes are made of, for example, nylon, polyester, polyvinylidene fluoride, polysulfone, silicon, fluorine resin, polyvinyl chloride, and the like.
　図１に示す通り、クリーンユニット１は、浄水フィルター１０を備える。浄水フィルター１０には給水口２０から水が注入される。タンク２５の水は、ポンプ２３の働きで給水管２１と給水口２０を介して浄水フィルター１０に送られる。ポンプ２３と給水口２０の間にはフィルター２２が備わる。フィルター２２の穴は中空糸膜の内径よりも小さい。 As shown in FIG. 1, the clean unit 1 includes a water purification filter 10. Water is injected into the water purification filter 10 from the water supply port 20 . Water in the tank 25 is sent to the water purification filter 10 through the water supply pipe 21 and the water supply port 20 by the action of the pump 23 . A filter 22 is provided between the pump 23 and the water supply port 20 . The holes of the filter 22 are smaller than the inner diameter of the hollow fiber membrane.
　図１に示す通り、クリーンユニット１は、リザーブタンク１５を備える。リザーブタンク１５は可撓性を備えた素材で成る。 As shown in FIG. 1, the clean unit 1 includes a reserve tank 15. The reserve tank 15 is made of flexible material.
　図１及び図２に示す通り、封止部８が、中空糸膜を備えた帯体２の端部（２ａ，２ｂ）を挟み止め、浄水フィルター１０の水を封止している。中空糸膜の中央付近（３ａ）は浄水フィルター１０内に配置される。 As shown in FIGS. 1 and 2, the sealing portion 8 clamps the ends (2a, 2b) of the strip 2 provided with the hollow fiber membrane and seals the water in the water purification filter 10. The vicinity of the center (3a) of the hollow fiber membrane is placed inside the water purification filter 10. As shown in FIG.
　図１に示す通り、封止部９が、中空糸膜を備えた帯体２の端部（２ｃ，２ｄ）を挟み止め、リザーブタンク１５の水を封止している。中空糸膜の一端３ｂと他端３ｃはリザーブタンク１５内に配置される。 As shown in FIG. 1, the sealing portion 9 sandwiches the ends (2c, 2d) of the strip 2 provided with the hollow fiber membranes to seal the water in the reserve tank 15. One end 3 b and the other end 3 c of the hollow fiber membrane are arranged in the reserve tank 15 .
　浄水フィルター１０とリザーブタンク１５への中空糸膜３の取り付けを、帯体２を封止部（８，９）で挟み込むことにより行う結果、中空糸膜３は、切れたり外れたりすることなく、浄水フィルター１０とリザーブタンク１５に取り付けることができる。すなわち、中空糸膜３の直径は０．３ｍｍから２ｍｍと細い。このため、帯体２を介さずに中空糸膜３を直接封止部（８，９）で挟み込む場合、中空糸膜３は、引張りや曲げの力を直接受けることになり破損しやすい。数ｃｍの幅で成る帯体２を介して挟み込むことにより、中空糸膜３は、引張や曲げの力を受けることなく浄水フィルター１０とリザーブタンク１５に固定される。この結果、取り付け箇所における中空糸膜３の破損を防止できる。 The hollow fiber membranes 3 are attached to the water purification filter 10 and the reserve tank 15 by sandwiching the band 2 between the sealing portions (8, 9). It can be attached to the water purification filter 10 and the reserve tank 15. - 特許庁That is, the diameter of the hollow fiber membrane 3 is as thin as 0.3 mm to 2 mm. Therefore, when the hollow fiber membranes 3 are directly sandwiched between the sealing portions (8, 9) without the band 2 interposed therebetween, the hollow fiber membranes 3 are easily damaged because they are directly subjected to tensile and bending forces. The hollow fiber membrane 3 is fixed to the water purifying filter 10 and the reserve tank 15 without being subjected to tensile or bending forces by being sandwiched between the strips 2 having a width of several centimeters. As a result, it is possible to prevent the hollow fiber membrane 3 from being damaged at the mounting location.
　被服に取り付ける場合、タンク２５の容積は５ｃｃくらいが適している。水が５ｃｃの場合、約１５分で全ての水が蒸発し終える。タンクの水が蒸発し終えた場合、外部から水の補充ができる。 When attaching to clothing, the volume of the tank 25 is suitable to be about 5cc. In the case of 5 cc of water, all the water will finish evaporating in about 15 minutes. When the water in the tank has finished evaporating, it can be replenished with water from the outside.
　図１及び図２によって、実施例１の作用を説明する。タンク２５の水がポンプ２３によって浄水フィルター１０に送られると、浄水フィルター１０内の水が中空糸膜３ａの微細孔４を介してり中空糸膜３ａ内に入る。その際、微細孔４の直径よりも粒が大きい水の汚れ７は、浄水フィルター１０に残る。これにより、中空糸膜３ａ内には、汚れの濾過された水が入る。中空糸膜３ａ内に入った水は、矢印Ａ、矢印Ｂの方向に進み、帯体を備えた位置に至る。帯体２の周辺には水がなく、また帯体２は吸水し易い素材で成るため、中空糸膜内の水は矢印で示す方向に滲み出る。 The action of the first embodiment will be explained with reference to FIGS. 1 and 2. FIG. When the water in the tank 25 is sent to the water purification filter 10 by the pump 23, the water in the water purification filter 10 enters the hollow fiber membranes 3a through the micropores 4 of the hollow fiber membranes 3a. At that time, water stains 7 having particles larger than the diameter of the micropores 4 remain on the water purification filter 10.例文帳に追加As a result, contaminant-filtered water enters the hollow fiber membrane 3a. The water that has entered the hollow fiber membrane 3a proceeds in the directions of arrows A and B and reaches the position provided with the band. Since there is no water around the band 2 and the band 2 is made of a material that easily absorbs water, the water in the hollow fiber membrane seeps out in the direction indicated by the arrow.
　ポンプ２５の水は、浄水フィルター１０に入る前にフィルター２２を通過する。フィルター２２により中空糸膜３の内径よりも小さな汚れを取り除く。これにより、中空糸膜の内部に異物が侵入することを防止できる。 The water from the pump 25 passes through the filter 22 before entering the water purification filter 10. Dirt smaller than the inner diameter of the hollow fiber membrane 3 is removed by the filter 22. - 特許庁This can prevent foreign matter from entering the inside of the hollow fiber membrane.
　帯体２に滲み出た水は、気化熱により帯体２を取り付けた衣服等を冷却する。 The water oozing out of the belt 2 cools the clothes, etc. to which the belt 2 is attached by the heat of vaporization.
　中空糸膜３内を流れた水のうち、帯体２に滲み出ずに残った水は、中空糸膜の端部開口（３ｂ，３ｃ）から流れ出て、リザーブタンク１５に溜まる。リザーブタンクが可撓性の素材で成るため、手指でぎゅっぎゅっと摘まむと、リザーブタンク内の水は中空糸膜の端部開口（３ｂ，３ｃ）から中空糸膜内に入る。リザーブタンクから中空糸膜に流れ込んだ水は、帯体２に滲み出ると共に、浄水フィルター１０に到達し、中空糸膜３ａの微細孔４から浄水フィルター１０に流れる。このとき、中空糸膜３ａの微細孔４に詰まった汚れは取り除かれ浄水フィルター１０内に流れ出る。この結果、中空糸膜の微細孔は詰まることなく維持できる。 Of the water that has flowed through the hollow fiber membranes 3 , the remaining water that has not oozed out into the band 2 flows out from the end openings ( 3 b , 3 c ) of the hollow fiber membranes and accumulates in the reserve tank 15 . Since the reserve tank is made of a flexible material, the water in the reserve tank enters the hollow fiber membranes through the end openings (3b, 3c) of the hollow fiber membranes when it is tightly pinched with fingers. The water that has flowed into the hollow fiber membranes from the reserve tank oozes out into the strip 2, reaches the water purification filter 10, and flows into the water purification filter 10 through the micropores 4 of the hollow fiber membranes 3a. At this time, dirt clogging the micropores 4 of the hollow fiber membrane 3 a is removed and flows out into the water purification filter 10 . As a result, the micropores of the hollow fiber membrane can be maintained without clogging.
　冷却装置１は、例えば、図７に示す通り、複数の帯体２を並列に並べ、浄水フィルター１０とリザーブタンク１５と共に布に取り付けてユニット状にして用いる。帯体と浄水フィルターとリザーブタンクを布に取り付ける手段は、縫製でもよいし、接着剤を用いてもよい。帯体が冷却機能を備えるので、製品の冷却したいに箇所に帯体が来るよう、製品にユニットを配置して取り付ける。ポンプは水の補給等の操作ができる位置に配置する。 For example, as shown in FIG. 7, the cooling device 1 is used as a unit by arranging a plurality of strips 2 in parallel and attaching them to cloth together with the water purification filter 10 and the reserve tank 15 . Means for attaching the strip, the water purification filter, and the reserve tank to the cloth may be sewn or an adhesive may be used. Since the strip has a cooling function, the unit is arranged and attached to the product so that the strip comes to the part of the product that is desired to be cooled. The pump should be placed in a position where it can be operated for water replenishment, etc.
　実施例１ポンプにより水の補充ができるため高い冷却効果が必要な場合に適している。一方、ポンプが衣類のデザイン性を妨げる場合がある。よって衣類の場合には作業着に用いるのに適している。 　Embodiment 1 Since water can be replenished with a pump, it is suitable when a high cooling effect is required. On the other hand, pumps can interfere with the design of clothing. Therefore, in the case of clothing, it is suitable for use as work clothes.
　図３を参照して実施例２を説明する。 Example 2 will be described with reference to FIG.
　実施例２の冷却装置では、浄水フィルターに給水した後、給水口２０を閉じて、給水管２１からタンク２５に至る給水のための装置を取り外す。給水口２０を閉じ、給水のための装置を取り外すことにより、冷却装置の軽量化が図られる。またポンプがないことによりデザインの自由度が得られる。従って、Ｔシャツ等、一般衣類に用いることができる。 In the cooling device of Example 2, after water is supplied to the water purification filter, the water supply port 20 is closed and the device for supplying water from the water supply pipe 21 to the tank 25 is removed. By closing the water supply port 20 and removing the device for supplying water, the weight of the cooling device can be reduced. In addition, freedom of design is obtained by not having a pump. Therefore, it can be used for general clothing such as T-shirts.
　浄水フィルター１０の水は中空糸膜３ａの微細孔から中空糸膜内に入り、一部の水は帯体２に浸み込む。浸み込まずに中空糸膜の端部開口（３ｂ，３ｃ）に至った水は、端部開口から排出され、リザーブタンク１５に溜まる。 The water of the water purification filter 10 enters the hollow fiber membrane through the micropores of the hollow fiber membrane 3a, and part of the water permeates the band 2. Water that reaches the end openings (3b, 3c) of the hollow fiber membranes without permeating is discharged from the end openings and accumulated in the reserve tank 15. As shown in FIG.
　図４を参照して実施例３を説明する。実施例３の冷却装置では、浄水タンク１０とリザーブタンク１５の両方にタンクがそなわる。 Example 3 will be described with reference to FIG. In the cooling device of Example 3, both the purified water tank 10 and the reserve tank 15 are provided with tanks.
　実施例３の冷却装置ではポンプを二つ備えるため、例えば衣類に用いた場合、暑い中屋外で労働するケース等、継続して冷却する必要がある場合に適している。ポンプ２３を利用してリザーブタンク側から浄水タンク側に水を流して中空糸膜内を自動的に洗浄することもできる。 Since the cooling device of Example 3 has two pumps, it is suitable for cases in which continuous cooling is required, such as when used for clothing or when working outdoors in the heat. It is also possible to use the pump 23 to flow water from the reserve tank side to the clean water tank side to automatically wash the inside of the hollow fiber membranes.
　図５を参照して実施例４を説明する。実施例４の冷却装置では、リザーブタンク１５の水を集めて、タンク２５に送り返す。これにより、水は循環する。水が循環することにより、帯２の部分では気化熱により中空糸膜３の内部の水の温度が下がり、これに加えて給水管２１とタンク２５を経由する過程で水の温度が下がる。従って、水の循環を繰り返すことにより、冷却効果を重ねて得ることができる。 Example 4 will be described with reference to FIG. In the cooling device of Example 4, the water in the reserve tank 15 is collected and sent back to the tank 25 . This allows the water to circulate. As the water circulates, the temperature of the water inside the hollow fiber membranes 3 drops due to the heat of vaporization in the zone 2, and the temperature of the water drops as it passes through the water supply pipe 21 and the tank 25. Therefore, by repeating the circulation of water, the cooling effect can be obtained repeatedly.
　実施例４の冷却装置は、ポンプを一つで済ませており、実施例３の簡易版ということができる。冷却するべき対象の面積が大きい製品に用いる場合には、ポンプを大きくする。 The cooling device of Example 4 uses only one pump, and can be said to be a simplified version of Example 3. If the product is to be cooled over a large area, the pump should be larger.
　図６を参照して実施例５を説明する。実施例５の冷却装置はリザーブタンク１５を備えない。実施例５の冷却装置では中空糸膜に水を供給するのは浄水フィルター１０のみである。水は、浄水フィルター１０に配置された中空糸膜の中央付近（３ａ）の微細孔４から中空糸膜に入る。 Example 5 will be described with reference to FIG. The cooling device of Example 5 does not include the reserve tank 15 . In the cooling device of Example 5, only the water purification filter 10 supplies water to the hollow fiber membranes. Water enters the hollow fiber membrane through the micropores 4 near the center (3a) of the hollow fiber membrane arranged in the water purification filter 10 .
　実施例５では、冷却装置を構成する部品数が少ないため、生産が容易でコストが安価で済む、というメリットがある。また、中空糸膜内には、中空糸膜の壁面の微細孔を介した水が供給されるため、中空糸膜内の水は異物を含んでおらず、中空糸膜を詰まらせることがない。また、帯体２において、周囲を冷却することができる。 　In the fifth embodiment, since the number of parts constituting the cooling device is small, there is an advantage that the production is easy and the cost is low. In addition, since water is supplied to the inside of the hollow fiber membranes through fine pores in the wall surface of the hollow fiber membranes, the water inside the hollow fiber membranes does not contain foreign matter, and the hollow fiber membranes are not clogged. . Moreover, in the strip 2, the surroundings can be cooled.
　実施例６（図示しない）では、実施例１から実施例５で用いた中空糸膜に代えて、内径が１ｍｍ～２ｍｍ、外径が２ｍｍ～４ｍｍの管を用いる。管は硬度４５度～５５度のシリコーンゴムで成る。管には０．１ｍｍ～０．３ｍｍの小孔が穿ってあり、管内の水が小孔から、管の外部に滲み出る。実施例６は、実施例１から実施例５で用いた中空糸膜がこのような管に代わるのみで、その他の構成は実施例１から実施例５と同様である。 In Example 6 (not shown), a tube with an inner diameter of 1 mm to 2 mm and an outer diameter of 2 mm to 4 mm is used instead of the hollow fiber membranes used in Examples 1 to 5. The tube is made of silicone rubber with a hardness of 45-55 degrees. A small hole of 0.1 mm to 0.3 mm is drilled in the tube, and the water in the tube seeps out from the small hole to the outside of the tube. In Example 6, the hollow fiber membranes used in Examples 1 to 5 are replaced with such a tube, and other configurations are the same as those in Examples 1 to 5.
　硬度４５度～５５度のシリコーンゴムは伸縮性が高いため、小孔から滲み出る水を吸収する帯体や、帯体を取り付けた冷却装置や冷却対象の伸縮に自在に追従する。 　Since silicone rubber with a hardness of 45 to 55 degrees is highly elastic, it freely follows the expansion and contraction of the belt that absorbs the water seeping out from the small holes, the cooling device that has the belt attached, and the object to be cooled.
