Description

熱交換器および熱交換システムHeat exchanger and heat exchange system
　本発明は流体間の熱の交換を行う熱交換器および熱交換システム、特に、飲料用の高温液体を低温流体により冷却するのに好適な熱交換器および熱交換システムに関するものである。 The present invention relates to a heat exchanger and a heat exchange system for exchanging heat between fluids, and more particularly to a heat exchanger and a heat exchange system suitable for cooling a high-temperature liquid for beverage with a low-temperature fluid.
　近年、ＷＨＯ（世界保健機関：World Health Organization）とＦＡＯ（国連食糧農業機関：Food and Agriculture Organization of the United Nations）が共同作成した「乳児用調整粉乳の安全な調乳、保存及び取扱いに関するガイドライン」によれば、乳児用の粉ミルクでは、エンテロバクター・サカザキなどへの感染による乳児の重篤な疾患や死亡との関連が報告されている。さらに、上記感染への防止対策として、乳児に与える粉ミルク調乳用の飲料水は、７０℃以上に沸かして使用しなければならない、とされている。このため、乳児に粉ミルクを調乳して与えるためには、７０℃程度で調乳したミルクを４０℃程度にまで冷却する必要がある。 “Guidelines for Safe Formulation, Storage and Handling of Infant Formulad Milk” jointly created by WHO (World Health Organization: World Health Organization) and FAO (Food and Agriculture Organization: Food Organization: of the United Nations) in recent years According to the report, infant milk powder has been associated with serious illness and death of infants due to infection with Enterobacter Sakazaki and others. Furthermore, as a countermeasure against the above-mentioned infection, it is said that the powdered milk preparation drinking water given to the infant must be boiled to 70 ° C. or higher. For this reason, in order to prepare powdered milk for infants, it is necessary to cool the milk prepared at about 70 ° C. to about 40 ° C.
　このような乳児用のミルクを高温から適温に冷却する方法としては、哺乳瓶内の高温のミルクを、水道水等を用いて外部から冷やすことが一般的である。 As a method for cooling the infant milk from a high temperature to an appropriate temperature, it is common to cool the high temperature milk in the baby bottle from the outside using tap water or the like.
　この冷却方法に関し、冷却を簡便化する手段として、例えば特許文献１に示す冷却容器が知られている。具体的には、特許文献１には、冷却容器に哺乳瓶を揺動可能に保持する保持手段を設け、冷却容器を揺動することにより哺乳瓶を揺動させ、これによって哺乳瓶内のミルクを攪拌するとともに、哺乳瓶の揺動により冷却容器内の冷媒を攪拌するようになっている。 Regarding this cooling method, as a means for simplifying cooling, for example, a cooling container shown in Patent Document 1 is known. Specifically, Patent Document 1 includes holding means for swingably holding the baby bottle in the cooling container, and the baby bottle is swung by swinging the cooling container, whereby the milk in the baby bottle In addition, the refrigerant in the cooling container is agitated by swinging the baby bottle.
　一方、乳児用のミルクに限らず、液体の冷却については一般に熱交換を用いる方法が採用されている。例えば特許文献２には、沸騰温度近くまで加熱された水を冷却用の水タンクの中を通る配管内に導いて冷却させることにより、湯冷ましを作る装置が示されている。 On the other hand, not only milk for infants but also a method using heat exchange is generally adopted for cooling liquids. For example, Patent Document 2 discloses an apparatus that cools hot water by introducing water that has been heated to near the boiling temperature into a pipe that passes through a cooling water tank and cooling it.
　また、特許文献３には、「黄金分割」に従った少なくとも１つの対数曲線にほぼ一致する彎曲を呈する作用面上に流体を流し、この作用面と、流体との間で熱交換を行う熱交換器が記載されている。 Further, in Patent Document 3, a fluid is allowed to flow on a working surface that exhibits a curvature that substantially matches at least one logarithmic curve according to the “golden section”, and heat is exchanged between the working surface and the fluid. An exchanger is described.
日本国公開特許公報「特開２０１１－２２９５９４号公報（２０１１年１１月１７日公開）」Japanese Patent Publication “JP 2011-229594 A (published on November 17, 2011)” 日本国特許第３０２９７３２号明細書（２０００年４月４日発行）Japanese Patent No. 3029732 (issued April 4, 2000) 日本国公表特許公報「特表２００５－５１３４１０号公報（２００５年５月１２日公表）」Japanese Patent Gazette "Special Table 2005-513410 Publication (May 12, 2005)"
　しかしながら、特許文献１に示す構成では、冷却容器を用いても５分以上の長い冷却時間が必要となっている。これは、特許文献１に示す構成では、哺乳瓶等の容器に入っているミルク等の液体を冷却容器内の冷媒によって冷却するものであるから、冷媒と接触する冷却対象物の面積が哺乳瓶等の容器の表面積に限られているためである。 However, in the configuration shown in Patent Document 1, a long cooling time of 5 minutes or more is required even if a cooling container is used. This is because, in the configuration shown in Patent Document 1, a liquid such as milk contained in a container such as a baby bottle is cooled by the refrigerant in the cooling container, so that the area of the cooling object in contact with the refrigerant is the baby bottle. This is because the surface area of the container is limited.
　さらに、特許文献１に示す構成では、予め冷却容器を数時間冷蔵庫で冷やしておく必要がある等、利便性にも課題がある。特に生後間もない乳児に粉ミルクを調乳して与える場合では、数時間おきにミルクを与える必要があるうえ、夜間もミルクを与える必要がある。このため、冷却容器を冷やすといった煩わしい作業は極力なくすことが望ましい。 Furthermore, in the configuration shown in Patent Document 1, there is a problem in convenience, for example, the cooling container needs to be cooled in a refrigerator for several hours in advance. In particular, when formulating and feeding infant formula to infants that are shortly after birth, it is necessary to feed milk every few hours and also to feed milk at night. For this reason, it is desirable to eliminate the troublesome work of cooling the cooling container as much as possible.
　また、特許文献２に示す構成では、特許文献１に示す構成と比較して液体の冷却時間が短時間となる。しかしながら、液体が流れる配管を取外して配管内を洗浄することが困難なうえ、配管内の状態を目視で確認することも困難である。そのため、調乳後のミルクに限らず、コーヒーやお茶といった飲料を衛生に保つことが困難である。 Further, in the configuration shown in Patent Document 2, the liquid cooling time is shorter than that in the configuration shown in Patent Document 1. However, it is difficult to remove the pipe through which the liquid flows and clean the inside of the pipe, and it is also difficult to visually check the state in the pipe. Therefore, it is difficult to keep beverages such as coffee and tea, not just milk after conditioning.
　また、特許文献３に示す構成では、液体流路が複雑な形状であるため、流路の洗浄および流路の状態確認を容易に行うことができず、衛生管理が困難となる。 Further, in the configuration shown in Patent Document 3, since the liquid flow path has a complicated shape, it is difficult to clean the flow path and confirm the state of the flow path, which makes hygiene management difficult.
　本発明は、上記の問題点に鑑みてなされたものであり、熱交換効率が良好であり、かつ流体流路の洗浄、消毒および状態確認が容易である熱交換器および熱交換システムの提供を目的としている。 The present invention has been made in view of the above-described problems, and provides a heat exchanger and a heat exchange system that have good heat exchange efficiency and that are easy to clean, disinfect, and check the state of a fluid flow path. It is aimed.
　上記の課題を解決するために、本発明の一態様に係る熱交換器は、容器形状を有する第１の流路形成部材と、前記第１の流路形成部材の内側に前記第１の流路形成部材に対して取り外し可能に配置された第２の流路形部材とを備え、前記第１の流路形成部材は、容器形状の周壁部の内周面の径が上部から下部に向かって漸次小さくなり、かつ熱交換用液体を流す第１流路が前記周壁部内に形成され、前記第１の流路形成部材の前記内周面と前記第２の流路形成部材の外周面との間には、これら内周面と外周面とによって前記熱交換用液体と熱交換される被熱交換液体を流す螺旋状の第２流路が形成されていることを特徴としている。 In order to solve the above-described problem, a heat exchanger according to one aspect of the present invention includes a first flow path forming member having a container shape, and the first flow path inside the first flow path forming member. A second flow path-shaped member that is detachably disposed with respect to the path forming member, wherein the first flow path forming member has a diameter of the inner peripheral surface of the container-shaped peripheral wall portion from the upper part to the lower part. A first flow path that gradually decreases and flows the heat exchange liquid is formed in the peripheral wall, and the inner peripheral surface of the first flow path forming member and the outer peripheral surface of the second flow path forming member A spiral second flow path is formed between the inner peripheral surface and the outer peripheral surface to allow the heat exchange liquid to exchange heat with the heat exchange liquid.
　本発明の一態様によれば、熱交換効率が良好であり、かつ流体流路の洗浄、消毒および状態確認が容易である。 According to one aspect of the present invention, the heat exchange efficiency is good, and the fluid flow path can be easily cleaned, disinfected, and checked.

Embodiments of the present invention will be described below with reference to the drawings. In addition, below, the heat exchanger which cools the milk adjusted to 70 degreeC to suitable temperature (about 40 degree | times) with water as an example is demonstrated. In the following description, a liquid to be cooled, such as milk, is referred to as a heat exchange liquid, and a liquid for cooling the heat exchange liquid, such as water, is referred to as a heat exchange liquid (for heat exchange). Fluid).
　(熱交換システムの構成)
　図１は、本発明の一実施形態に係る熱交換システムの構成を示す模式図である。図１に示すように、熱交換システム１００は、熱交換器１、タンク（貯蔵部）２およびポンプ（供給部）３を含む。 (Configuration of heat exchange system)
FIG. 1 is a schematic diagram showing a configuration of a heat exchange system according to an embodiment of the present invention. As shown in FIG. 1, the heat exchange system 100 includes a heat exchanger 1, a tank (storage unit) 2, and a pump (supply unit) 3.
　熱交換器１は、熱交換用液体１３０と被熱交換液体１１０との間で熱交換を行うものである。熱交換器１は、タンク２およびポンプ３とそれぞれ接続されている。タンク２は、熱交換用液体１３０を貯蔵するものである。ポンプ３は、タンク２に貯蔵されている熱交換用液体１３０を熱交換器１へ送り出すものである。 The heat exchanger 1 performs heat exchange between the heat exchange liquid 130 and the heat exchange liquid 110. The heat exchanger 1 is connected to the tank 2 and the pump 3 respectively. The tank 2 stores the heat exchange liquid 130. The pump 3 sends out the heat exchange liquid 130 stored in the tank 2 to the heat exchanger 1.
　熱交換用液体１３０は、タンク２、ポンプ３および熱交換器１を循環する。具体的には、熱交換用液体１３０は、ポンプ３によってタンク２から熱交換器１に送られ、熱交換器１の中に配設されている流路内を通って被熱交換液体１１０と熱交換した後、タンク２に戻される。 The heat exchange liquid 130 circulates through the tank 2, the pump 3 and the heat exchanger 1. Specifically, the heat exchange liquid 130 is sent from the tank 2 to the heat exchanger 1 by the pump 3, passes through the flow path disposed in the heat exchanger 1, and the heat exchange liquid 110. After heat exchange, it is returned to the tank 2.
　熱交換器１の上部には被熱交換液体出口４が配置されており、被熱交換液体出口４から熱交換を受ける被熱交換液体１１０が熱交換器１に注がれる。熱交換器１は上方から注がれた被熱交換液体１１０を流す流路を有する。被熱交換液体１１０は熱交換器１の流路内を上から下に自重で流れ落ち、この間に熱交換用液体１３０と被熱交換液体１１０との熱交換が行われる。その後、被熱交換液体１１０は、熱交換器１から流出し、カップ５内に注がれる。被熱交換液体１１０が乳児用のミルクであれば、カップ５に代えて哺乳瓶を直接置いてもよい。 A heat exchange liquid outlet 4 is disposed at the top of the heat exchanger 1, and a heat exchange liquid 110 that receives heat exchange from the heat exchange liquid outlet 4 is poured into the heat exchanger 1. The heat exchanger 1 has a flow path for flowing the heat exchange liquid 110 poured from above. The heat exchange liquid 110 flows down from the top to the bottom in the flow path of the heat exchanger 1, and during this time, heat exchange between the heat exchange liquid 130 and the heat exchange liquid 110 is performed. Thereafter, the heat exchange liquid 110 flows out of the heat exchanger 1 and is poured into the cup 5. If the heat exchange liquid 110 is milk for infants, a baby bottle may be placed directly instead of the cup 5.
　また、ポンプ３にて熱交換器１への熱交換用液体１３０の送り流量を変化させることにより、熱交換器１での被熱交換液体１１０に対する熱交換量を変えることができる。これにより、熱交換器１から流出する被熱交換液体１１０の温度を調整することができる。この場合、流量を増やすと被熱交換液体１１０の温度は熱交換用液体１３０の温度に近づく方向に変化し、流量を減らすと遠ざかる方向に変化する。具体的には、例えば、低温の熱交換用液体１３０によって高温の被熱交換液体１１０を冷却するため、熱交換用液体１３０の送り流量を増加させると、熱交換器１から流出する被熱交換液体１１０の温度は低下する。一方、熱交換用液体１３０の送り流量を減少させると、熱交換器１から流出する被熱交換液体１１０の温度は上昇する。 Further, by changing the feed flow rate of the heat exchange liquid 130 to the heat exchanger 1 by the pump 3, the heat exchange amount with respect to the heat exchange liquid 110 in the heat exchanger 1 can be changed. Thereby, the temperature of the to-be-heated liquid 110 flowing out from the heat exchanger 1 can be adjusted. In this case, when the flow rate is increased, the temperature of the heat exchange liquid 110 changes in a direction approaching the temperature of the heat exchange liquid 130, and when the flow rate is reduced, the temperature changes in a direction away from the heat exchange liquid 110. Specifically, for example, in order to cool the high-temperature heat exchange liquid 110 with the low-temperature heat exchange liquid 130, when the feed flow rate of the heat exchange liquid 130 is increased, the heat exchange flowing out from the heat exchanger 1 is performed. The temperature of the liquid 110 decreases. On the other hand, when the feed flow rate of the heat exchange liquid 130 is decreased, the temperature of the heat exchange liquid 110 flowing out of the heat exchanger 1 increases.
　(熱交換器１の構成)
　次に、熱交換器１の構成について説明する。図２は熱交換器１の外観を示す斜視図である。図３は、図２に示した熱交換器１の分解斜視図である。図４は、図１に示した熱交換器１の縦断面を含む斜視図である。図５の(ａ)は図４に示したＡ部の拡大図であり、図５の(ｂ)は図４に示したＢ部の拡大図である。 (Configuration of heat exchanger 1)
Next, the configuration of the heat exchanger 1 will be described. FIG. 2 is a perspective view showing the appearance of the heat exchanger 1. FIG. 3 is an exploded perspective view of the heat exchanger 1 shown in FIG. FIG. 4 is a perspective view including a longitudinal section of the heat exchanger 1 shown in FIG. FIG. 5A is an enlarged view of a portion A shown in FIG. 4, and FIG. 5B is an enlarged view of a portion B shown in FIG.
　図３に示すように、熱交換器１は、主要部品として、流路形成第１部材（流路形成内側部材）１１、流路形成第２部材１２および流路形成第３部材（流路形成外側部材）１３を備え、その他、シール部材１４、締結第１部材１５および締結第２部材１６を備えている。 As shown in FIG. 3, the heat exchanger 1 includes, as main components, a flow path forming first member (flow path forming inner member) 11, a flow path forming second member 12, and a flow path forming third member (flow path forming). An outer member 13, and a seal member 14, a fastening first member 15, and a fastening second member 16.
　流路形成第１～第３部材１１～１３は、略円錐形を有し、円錐形の底面を上にして配置され、その底面が開放された容器形状を有する。この形状は、例えば漏斗の円錐部分とほぼ同じ形状である。流路形成第２部材１２は流路形成第１部材１１の内面（内側）に配置され、流路形成第３部材１３は流路形成第１部材１１の外面に配置されている。すなわち、熱交換器１は、流路形成第３部材１３の中に流路形成第１部材１１を配置し、流路形成第１部材１１の中に流路形成第２部材１２を配置し、これら流路形成第１～第３部材１１～１３を重ね合わせることにより形成されている。ここで、図２～図４では、円錐部分の中心軸をＺ軸とし、この円錐部分の中心軸（Ｚ軸）と直交する軸をそれぞれＸ軸、Ｙ軸として示している。 The flow path forming first to third members 11 to 13 have a substantially conical shape, are arranged with the bottom surface of the conical shape facing up, and have a container shape with the bottom surface opened. This shape is substantially the same as the conical portion of the funnel, for example. The flow path forming second member 12 is disposed on the inner surface (inside) of the flow path forming first member 11, and the flow path forming third member 13 is disposed on the outer surface of the flow path forming first member 11. That is, the heat exchanger 1 arranges the flow path forming first member 11 in the flow path forming third member 13, arranges the flow path forming second member 12 in the flow path forming first member 11, These flow path forming first to third members 11 to 13 are formed by overlapping them. Here, in FIGS. 2 to 4, the central axis of the conical portion is shown as the Z axis, and the axes orthogonal to the central axis (Z axis) of the conical portion are shown as the X axis and Y axis, respectively.
　流路形成第１部材１１は、本体部分である円錐部１１１、および鍔部１１２を有している。鍔部１１２は、円錐部１１１の上端部において、円錐部１１１の周りに水平（Ｚ軸に対して垂直）に形成されている。流路形成第１部材１１の下端部には、下端開口部１１３が形成されている。 The flow path forming first member 11 has a conical portion 111 and a flange portion 112 which are main body portions. The flange portion 112 is formed horizontally (perpendicular to the Z axis) around the conical portion 111 at the upper end portion of the conical portion 111. A lower end opening 113 is formed at the lower end of the flow path forming first member 11.
　流路形成第１部材１１は、例えば、薄板の金属板をプレス成型することによって形成されている。このようにして流路形成第１部材１１を形成する場合には、安価かつ耐食性のある金属、例えばＳＵＳを使用することができる。また、金属部材であるため、樹脂成型材と比べて熱伝導率が高く、被熱交換液体１１０と熱交換用液体１３０との熱交換効率を向上させることができる。 The flow path forming first member 11 is formed, for example, by press molding a thin metal plate. Thus, when forming the flow path formation 1st member 11, a cheap and corrosion-resistant metal, for example, SUS, can be used. Moreover, since it is a metal member, its heat conductivity is higher than that of the resin molding material, and the heat exchange efficiency between the heat exchange liquid 110 and the heat exchange liquid 130 can be improved.
　流路形成第２部材１２は、本体部分である円錐部１２１、および処理液体受入部１２３を有している。円錐部１２１の外周面（側面）には、外周面に対して例えばＶ字形に凹んだ形状の螺旋溝１２２が上部から下部に亘って形成されている。なお、Ｖ字形の螺旋溝１２２は、詳細には、第１の内面が溝の底（Ｖ字の谷底）から略水平に伸び、第２の内面が溝の底（Ｖ字の谷底）から第１の内面に対して９０度以上の角度で下向きに延びた形状である。この点は、以下の他の実施の形態においても同様である。 The flow path forming second member 12 has a conical part 121 which is a main body part, and a processing liquid receiving part 123. On the outer peripheral surface (side surface) of the conical portion 121, a spiral groove 122 having a V-shaped recess with respect to the outer peripheral surface is formed from the upper part to the lower part. In detail, the V-shaped spiral groove 122 has a first inner surface extending substantially horizontally from the groove bottom (V-shaped valley bottom) and a second inner surface extending from the groove bottom (V-shaped valley bottom). This is a shape extending downward at an angle of 90 degrees or more with respect to the inner surface of one. This also applies to the other embodiments described below.
　円錐部１２１の外周面に螺旋溝１２２が形成されていることにより、流路形成第１部材１１の内面に流路形成第２部材１２を配置した場合に、流路形成第１部材１１の内面と流路形成第２部材１２の外面との間に、螺旋状の第２流路１１４が形成される。この第２流路１１４は、被熱交換液体１１０が流れる流路である。 Since the spiral groove 122 is formed on the outer peripheral surface of the conical portion 121, the inner surface of the flow path forming first member 11 can be obtained when the flow path forming second member 12 is disposed on the inner surface of the flow path forming first member 11. And a second channel 114 having a spiral shape is formed between the outer surface of the channel-forming second member 12. The second flow path 114 is a flow path through which the heat exchange liquid 110 flows.
　流路形成第２部材１２の下端部は閉じた構造であり、流路形成第１部材１１の内面に流路形成第２部材１２を配置した状態において、流路形成第２部材１２の下端部の下面と流路形成第１部材１１の下端部の上面との間には、所定高さの隙間が形成されるようになっている。 The lower end of the flow path forming second member 12 has a closed structure, and the lower end of the flow path forming second member 12 in a state where the flow path forming second member 12 is disposed on the inner surface of the flow path forming first member 11. A gap having a predetermined height is formed between the lower surface of the first member 11 and the upper surface of the lower end of the flow path forming first member 11.
　処理液体受入部１２３は、円錐部１２１の上端部の外周部に、環状の溝状に形成されている。処理液体受入部１２３の底面には、液体流入口１２４が形成されている。これにより、被熱交換液体出口４から処理液体受入部１２３に注入された被熱交換液体１１０は、液体流入口１２４から流路形成第１部材１１と流路形成第２部材１２との間の第２流路１１４に流入する。 The treatment liquid receiving portion 123 is formed in an annular groove shape on the outer peripheral portion of the upper end portion of the conical portion 121. A liquid inlet 124 is formed on the bottom surface of the processing liquid receiving portion 123. As a result, the heat exchange liquid 110 injected from the heat exchange liquid outlet 4 into the treatment liquid receiving portion 123 is transferred between the flow path formation first member 11 and the flow path formation second member 12 from the liquid inlet 124. It flows into the second flow path 114.
　流路形成第２部材１２は、例えば金型を使用した樹脂の成型によって形成される。この場合、流路形成第２部材１２は、螺旋溝１２２を含め、ＸＹ平面に対して、鉛直方向（Ｚ軸方向）にアンダーカットが生じない、抜き勾配を付けやすい形状とされる。流路形成第２部材１２は、樹脂成型にて作製する場合、低コストかつ容易に作製することができる。 The flow path forming second member 12 is formed, for example, by resin molding using a mold. In this case, the flow path forming second member 12 includes the spiral groove 122 and has a shape in which an undercut is not generated in the vertical direction (Z-axis direction) with respect to the XY plane and a draft is easily provided. The flow path forming second member 12 can be easily manufactured at low cost when manufactured by resin molding.
　流路形成第３部材１３は、本体部分である円錐部１３６、および鍔部１３５を有している。鍔部１３５は、円錐部１３６の上端部において、円錐部１３６の周りに水平（Ｚ軸に対して垂直）に形成されている。流路形成第１部材１１の下端部には、下端開口部１３３が成されている。 The flow path forming third member 13 has a conical portion 136 and a flange portion 135 which are main body portions. The collar portion 135 is formed horizontally (perpendicular to the Z axis) around the conical portion 136 at the upper end portion of the conical portion 136. A lower end opening 133 is formed at the lower end of the flow path forming first member 11.
　流路形成第３部材１３を流路形成第１部材１１の外面に配置した状態において、流路形成第３部材１３の下端部の上面に、流路形成第１部材１１の下端部の下面が配置される。詳細には、流路形成第３部材１３の下端開口部１１３の周りには、図５の(ｂ)に示すように、Ｏリング１８が設けられており、流路形成第１部材１１の下端部の下面はＯリング１８上に配置される。 In the state where the flow path forming third member 13 is disposed on the outer surface of the flow path forming first member 11, the lower surface of the lower end portion of the flow path forming first member 11 is on the upper surface of the lower end portion of the flow path forming third member 13. Be placed. Specifically, as shown in FIG. 5B, an O-ring 18 is provided around the lower end opening 113 of the flow path forming third member 13, and the lower end of the flow path forming first member 11. The lower surface of the part is disposed on the O-ring 18.
　また、鍔部１３５の上に、シール部材１４を介して、流路形成第１部材１１の鍔部１１２が配置される。さらに、流路形成第３部材１３の円錐部１３６の内周面と流路形成第１部材１１の円錐部１１１の外周面との間に第１流路１３４が形成される。この第１流路１３４は、熱交換用液体１３０が流れる流路である。 Further, the flange portion 112 of the flow path forming first member 11 is disposed on the flange portion 135 via the seal member 14. Furthermore, a first flow path 134 is formed between the inner peripheral surface of the conical portion 136 of the flow path forming third member 13 and the outer peripheral surface of the conical portion 111 of the flow path forming first member 11. The first flow path 134 is a flow path through which the heat exchange liquid 130 flows.
　流路形成第３部材１３の円錐部１３６の外面には、第１流路１３４とつながっている液体入口１３１および液体出口１３２が形成されている。液体入口１３１は、ポンプ３によって供給される熱交換用液体１３０の第１流路１３４すなわち熱交換器１への流入口である。液体出口１３２は、第１流路１３４すなわち熱交換器１から排出される熱交換用液体１３０の流出口である。液体入口１３１は円錐部１３６の下端部付近に設けられ、液体出口１３２は円錐部１３６の上端部付近に設けられている。 A liquid inlet 131 and a liquid outlet 132 connected to the first flow path 134 are formed on the outer surface of the conical portion 136 of the flow path forming third member 13. The liquid inlet 131 is an inlet of the first flow path 134 of the heat exchange liquid 130 supplied by the pump 3, that is, the heat exchanger 1. The liquid outlet 132 is an outlet for the heat exchange liquid 130 discharged from the first flow path 134, that is, the heat exchanger 1. The liquid inlet 131 is provided near the lower end portion of the conical portion 136, and the liquid outlet 132 is provided near the upper end portion of the conical portion 136.
　シール部材１４は、薄い平板のリング形状であり、流路形成第３部材１３の鍔部１３５と流路形成第１部材１１の鍔部１１２との間に配置されている。鍔部１３５と鍔部１１２は固定部材（図示せず）により互いに固定されている。このような構成により、第１流路１３４における上端部の位置すなわち両鍔部１３５，１１２の位置がシールされている。 The seal member 14 has a thin flat ring shape, and is disposed between the flange 135 of the flow path forming third member 13 and the flange 112 of the flow path forming first member 11. The collar part 135 and the collar part 112 are fixed to each other by a fixing member (not shown). With such a configuration, the position of the upper end portion of the first flow path 134, that is, the positions of both flange portions 135 and 112 are sealed.
　締結第１部材１５は、図４に示すように、頭部を有する雄ねじ形状であり、中心部に上端部から下端部に達する貫通孔が形成されている。この貫通孔は、第２流路１１４からの被熱交換液体１１０の排出口１７となっている。 As shown in FIG. 4, the fastening first member 15 has a male screw shape having a head, and a through hole reaching the lower end from the upper end to the center is formed. This through hole serves as a discharge port 17 for the heat exchange liquid 110 from the second flow path 114.
　締結第１部材１５は、頭部が流路形成第１部材１１の下端部の上面に配置され、雄ねじ部が流路形成第１部材１１の下端開口部１１３および流路形成第３部材１３の下端開口部１３３を貫通して下方へ突出した状態に配置されている。 The fastening first member 15 has a head disposed on the upper surface of the lower end portion of the flow path forming first member 11, and a male screw portion of the lower end opening 113 of the flow path forming first member 11 and the flow path forming third member 13. It arrange | positions in the state which penetrated the lower end opening part 133 and protruded below.
　締結第２部材１６は雌ねじであり、流路形成第３部材１３の下端開口部１３３から突出している締結第１部材１５の雄ねじ部に締結されている。したがって、締結第１部材１５および締結第２部材１６により、流路形成第１部材１１および流路形成第３部材１３の下端部同士がＯリング１８を介して締結されている。これにより、第１流路１３４における下端部の位置、すなわち流路形成第１部材１１の下端部と流路形成第３部材１３の下端部との位置がシールされている。 The fastening second member 16 is a female screw, and is fastened to the male screw portion of the fastening first member 15 protruding from the lower end opening 133 of the flow path forming third member 13. Therefore, the lower ends of the flow path forming first member 11 and the flow path forming third member 13 are fastened together via the O-ring 18 by the fastening first member 15 and the fastening second member 16. Thereby, the position of the lower end part in the 1st flow path 134, ie, the position of the lower end part of the flow path formation 1st member 11, and the lower end part of the flow path formation 3rd member 13, is sealed.
　上記のように、流路形成第１部材１１と流路形成第３部材１３とを組み合わせて形成される第１流路１３４は、上端部および下端部において適切にシールされているので、第１流路１３４の中の熱交換用液体１３０が漏れる事態、あるいは熱交換用液体１３０が第２流路１１４の被熱交換液体１１０と混ざり合う事態が確実に防止されている。 As described above, the first flow path 134 formed by combining the flow path forming first member 11 and the flow path forming third member 13 is appropriately sealed at the upper end portion and the lower end portion. A situation in which the heat exchange liquid 130 in the flow path 134 leaks or a situation in which the heat exchange liquid 130 is mixed with the heat exchange liquid 110 in the second flow path 114 is reliably prevented.
　（熱交換器１の材質および製造）
　熱交換器１は、被熱交換液体１１０として、乳児用のミルクや飲料用の液体を処理するものであるから、衛生上に問題がないように扱われる。そのため、使用前あるいは使用後には、通常、洗剤等で洗浄した後、煮沸消毒や薬液による消毒がなされる。薬液として多く用いられるのは、次亜塩素酸ナトリウムを含有した消毒薬であり、通常は、０．０１２５％程度に薄めて使用される。 (Material and production of heat exchanger 1)
Since the heat exchanger 1 is for treating milk for infants or liquid for beverages as the heat exchange liquid 110, it is handled so that there is no problem in terms of hygiene. Therefore, before use or after use, it is usually washed with a detergent or the like and then boiled or disinfected with a chemical solution. Disinfectant containing sodium hypochlorite is often used as a chemical solution, and is usually used diluted to about 0.0125%.
　ここで、熱交換器１の材質は、熱伝導率の高いものが好ましく、金属、特に、アルミや銅系の材料が最適である。熱交換器１は、金属材料にて作製される場合、鋳造やダイカスト成形などにより型成型され、その後、表面がフッ素塗料等によりコーティングされ、耐食性が付与される。 Here, the material of the heat exchanger 1 is preferably a material having high thermal conductivity, and metal, particularly aluminum or copper-based material is optimal. When the heat exchanger 1 is made of a metal material, it is molded by casting, die casting, or the like, and then the surface is coated with a fluorine paint or the like to impart corrosion resistance.
　しかしながら、消毒薬に含まれる上記の次亜塩素酸ナトリウムは、金属に対して腐食性があるため、熱交換器１には特殊なコーティングを行う必要がある。これは、通常のコーティングでは気孔が生じ、その気孔から熱交換器１が浸食されてしまうためである。このように、熱交換器１に対して特殊なコーティングを行う場合、熱交換器１の製造コストは非常に高価になる。 However, the above-mentioned sodium hypochlorite contained in the disinfectant is corrosive to metals, and therefore it is necessary to perform a special coating on the heat exchanger 1. This is because pores are formed in the normal coating, and the heat exchanger 1 is eroded from the pores. Thus, when performing special coating with respect to the heat exchanger 1, the manufacturing cost of the heat exchanger 1 becomes very expensive.
　また、鋳造やダイカスト成形では、材料が完全に充填されない箇所が発生することが多い。このように材料が充填されずに空間が形成された場合、その熱伝導率が変わり、熱交換器１としての能力にバラツキを生じさせてしまう。そのため、歩留りの低下が発生し、高コストとなってしまうといった問題が生じる。 Also, in casting and die casting, there are many cases where the material is not completely filled. When the space is formed without being filled with the material in this way, the thermal conductivity is changed, and the ability as the heat exchanger 1 is varied. Therefore, there arises a problem that the yield is reduced and the cost is increased.
　一方、次亜塩素酸ナトリウムを含有した消毒薬に耐性を持つ金属としては、モリブデンが添加されているＳＵＳ３１６、ＳＵＳ３１７、ＳＵＳ４４４、ＳＵＳ４４７Ｊ１、ＳＵＳＸＭ２７、ＳＵＳ３２９Ｊ２Ｌ、あるいはクロム含有量の多いステンレスが知られている。このような金属を使用して熱交換器１を安価に作製するにはプレス成型が最も望ましい。 On the other hand, as a metal having resistance to a disinfectant containing sodium hypochlorite, SUS316, SUS317, SUS444, SUS447J1, SUSXM27, SUS329J2L to which molybdenum is added, or stainless steel having a high chromium content is known. . In order to manufacture the heat exchanger 1 at low cost using such a metal, press molding is most desirable.
　なお、流路形成第１～第３部材１１～１３のうち、流路形成第１部材１１は被熱交換液体１１０および熱交換用液体１３０と直接に接する。したがって、流路形成第１部材１１を金属で作製することは熱交換効率の向上において最も効率が良い。 Of the flow path forming first to third members 11 to 13, the flow path forming first member 11 is in direct contact with the heat exchange liquid 110 and the heat exchange liquid 130. Therefore, producing the flow path forming first member 11 with metal is most efficient in improving the heat exchange efficiency.
　また、熱交換器１において、被熱交換液体１１０と熱交換用液体１３０との熱交換効率を向上させるためには、被熱交換液体１１０と熱交換用液体１３０とが接する表面積を増加させることが好ましい。しかしながら、プレス成型では、流路形成第１～第３部材１１～１３を複雑な形状にした場合、金型が高額になることから、コスト増加につながる。 In the heat exchanger 1, in order to improve the heat exchange efficiency between the heat exchange liquid 110 and the heat exchange liquid 130, the surface area where the heat exchange liquid 110 and the heat exchange liquid 130 are in contact with each other is increased. Is preferred. However, in the press molding, if the flow path forming first to third members 11 to 13 are complicated, the mold becomes expensive, leading to an increase in cost.
　そこで、本実施の形態の熱交換器１では、被熱交換液体１１０と熱交換用液体１３０との熱交換効率を向上させるために、被熱交換液体１１０が流れる第２流路１１４の流路長を長くしている。具体的には、第２流路１１４を螺旋状とすることにより、被熱交換液体１１０の流路長を長くしている。 Therefore, in the heat exchanger 1 of the present embodiment, in order to improve the heat exchange efficiency between the heat exchange liquid 110 and the heat exchange liquid 130, the flow path of the second flow path 114 through which the heat exchange liquid 110 flows. The length is long. Specifically, the flow path length of the heat exchange liquid 110 is increased by making the second flow path 114 spiral.
　なお、本来、流路形成第２部材１２は、流路形成第１部材１１と同様、金属にて形成することが、熱交換効率向上の点から望ましい。しかしながら、前述のコスト増の点から、流路形成第２部材１２を金属にて形成することは困難である。一方、流路形成第２部材１２の主な役割は被熱交換液体１１０が流れる第２流路１１４を長くすることであるから、流路形成第２部材１２を熱伝導率の低い樹脂にて形成しても、熱交換器１の性能低下を少なくすることができる。 In addition, it is originally desirable that the flow path forming second member 12 is formed of metal, like the flow path forming first member 11, from the viewpoint of improving the heat exchange efficiency. However, it is difficult to form the flow path forming second member 12 from metal from the above-mentioned point of cost increase. On the other hand, since the main role of the flow path forming second member 12 is to lengthen the second flow path 114 through which the heat exchange liquid 110 flows, the flow path forming second member 12 is made of a resin having low thermal conductivity. Even if it forms, the performance fall of the heat exchanger 1 can be decreased.
　上記の構成において、熱交換器１の動作について以下に説明する。図６は、熱交換器１の使用状態を示す縦断面図である。 The operation of the heat exchanger 1 in the above configuration will be described below. FIG. 6 is a vertical cross-sectional view showing the usage state of the heat exchanger 1.
　被熱交換液体１１０が被熱交換液体出口４（図１参照）から熱交換器１の処理液体受入部１２３に注がれると、被熱交換液体１１０は、処理液体受入部１２３の液体流入口１２４を経て第２流路１１４に流入する。第２流路１１４に流入した被熱交換液体１１０は、螺旋状の第２流路１１４に沿って熱交換器１の上部から下部へ流れる。その後、被熱交換液体１１０は、熱交換器１の下端部の排出口１７から排出され、カップ５（図１参照）に注がれる。 When the heat exchange liquid 110 is poured from the heat exchange liquid outlet 4 (see FIG. 1) into the processing liquid receiving portion 123 of the heat exchanger 1, the heat exchange liquid 110 becomes a liquid inlet of the processing liquid receiving portion 123. It flows into the second flow path 114 via 124. The heat exchange liquid 110 flowing into the second flow path 114 flows from the upper part to the lower part of the heat exchanger 1 along the spiral second flow path 114. Thereafter, the heat exchange liquid 110 is discharged from the discharge port 17 at the lower end of the heat exchanger 1 and poured into the cup 5 (see FIG. 1).
　一方、熱交換用液体１３０は、タンク２からポンプ３によって熱交換器１に送られる。この場合、熱交換用液体１３０は、熱交換器１の下部の液体入口１３１から第１流路１３４内に流れ込み、熱交換器１の上部の液体出口１３２から第１流路１３４外へ排出され、タンク２に戻される。 On the other hand, the heat exchange liquid 130 is sent from the tank 2 to the heat exchanger 1 by the pump 3. In this case, the heat exchange liquid 130 flows into the first flow path 134 from the liquid inlet 131 at the bottom of the heat exchanger 1, and is discharged out of the first flow path 134 from the liquid outlet 132 at the top of the heat exchanger 1. , Returned to the tank 2.
　したがって、被熱交換液体１１０は、第２流路１１４を流れる間に、第１流路１３４を流れる熱交換用液体１３０と熱交換される。この場合、第２流路１１４は螺旋状に形成され、流路長が長くなっている。これにより、第２流路１１４の流量当たりにおいて、被熱交換液体１１０が流路形成第１部材１１と接触する面積が大きくなる。すなわち、第２流路１１４の流量当たりにおいて、被熱交換液体１１０が流路形成第１部材１１を介して２流路１３４の熱交換用液体１３０と接触する面積が大きくなる。この結果、被熱交換液体１１０と熱交換用液体１３０との熱交換の効率が向上する。 Therefore, the heat exchange liquid 110 is heat exchanged with the heat exchange liquid 130 flowing through the first flow path 134 while flowing through the second flow path 114. In this case, the second flow path 114 is formed in a spiral shape, and the flow path length is long. Thereby, the area where the heat exchange liquid 110 contacts the flow path forming first member 11 increases per flow rate of the second flow path 114. That is, the area where the heat exchange liquid 110 comes into contact with the heat exchange liquid 130 in the second flow path 134 via the flow path forming first member 11 increases per flow rate of the second flow path 114. As a result, the efficiency of heat exchange between the heat exchange liquid 110 and the heat exchange liquid 130 is improved.
　なお、液体入口１３１および液体出口１３２に、差し込み口のある固定台を別途設けておくことにより、熱交換器１と熱交換用液体を通る配管との抜き差しが簡便になる。また、液体入口１３１および液体出口１３２において、シリコーンチューブなどの配管をホースバンド等にて固定してもよい。 It should be noted that by separately providing a fixing base having an insertion port at the liquid inlet 131 and the liquid outlet 132, the heat exchanger 1 and the pipe passing through the heat exchange liquid can be easily inserted and removed. Further, at the liquid inlet 131 and the liquid outlet 132, piping such as a silicone tube may be fixed with a hose band or the like.
　熱交換器１では、流路形成第１部材１１と、流路形成第２部材１２と、流路形成第３部材１３とは容易に分解可能である。したがって、流路形成第２部材１２を流路形成第１部材１１から取りは外して、円錐部１１１の洗浄、消毒および状態確認（特に衛生上の問題の有無の確認）を容易に行うことができる。これにより、被熱交換液体１１０が流れる流路の衛生管理が容易である。また、流路形成第３部材１３を取り外すことにより、熱交換用液体１３０が流れる第１流路１３４の洗浄、および、第１流路１３４の状態確認を容易に行うことができる。 In the heat exchanger 1, the flow path forming first member 11, the flow path forming second member 12, and the flow path forming third member 13 can be easily disassembled. Therefore, the flow path forming second member 12 is removed from the flow path forming first member 11, and the conical portion 111 can be easily cleaned, disinfected, and checked for conditions (particularly, checking for sanitary problems). it can. Thereby, hygiene management of the flow path through which the heat exchange liquid 110 flows is easy. Further, by removing the flow path forming third member 13, it is possible to easily clean the first flow path 134 through which the heat exchange liquid 130 flows and to check the state of the first flow path 134.
　また、流路形成第１部材１１、流路形成第２部材１２および流路形成第３部材１３はプレス成型や型成型によって容易に作製することができるため、製造コストを低減することができる。 Moreover, since the flow path forming first member 11, the flow path forming second member 12, and the flow path forming third member 13 can be easily manufactured by press molding or mold molding, the manufacturing cost can be reduced.
　また、流路形成第３部材１３において、液体入口１３１は下部に設けられ、液体出口１３２は上部に設けられている。これにより、熱交換用液体１３０が流れる第１流路１３４内に存在する空気を追い出しやすくなり、熱交換用液体１３０と被熱交換液体１１０との熱交換効率の低下を防止することができる。なお、液体入口１３１と液体出口１３２との位置関係はこれに限定されず、液体入口１３１が上部に設けられ、液体出口１３２が下部に設けられていてもよい。 Further, in the flow path forming third member 13, the liquid inlet 131 is provided at the lower part, and the liquid outlet 132 is provided at the upper part. Thereby, it becomes easy to drive out the air existing in the first flow path 134 through which the heat exchange liquid 130 flows, and it is possible to prevent the heat exchange efficiency between the heat exchange liquid 130 and the heat exchange liquid 110 from being lowered. The positional relationship between the liquid inlet 131 and the liquid outlet 132 is not limited to this, and the liquid inlet 131 may be provided at the upper part and the liquid outlet 132 may be provided at the lower part.
　なお、熱交換器１において、第１流路１３４および第２流路１１４を形成する流路形成第１～第３部材１１～１３の形状は、円錐形に限定されない。例えば、第２流路１１４は、上部から下部に向かって径が漸次小さくなる螺旋状に形成されていればよく、流路形成第１部材１１および流路形成第２部材１２は、このような第２流路１１４を形成できるもの、流路形成第３部材１３は、流路形成第１部材１１に対応した形状を有するものであってもよい。上記の点は、後述する他の実施の形態の熱交換器においても同様である。 In the heat exchanger 1, the shape of the flow path forming first to third members 11 to 13 that form the first flow path 134 and the second flow path 114 is not limited to a conical shape. For example, the second flow path 114 only needs to be formed in a spiral shape whose diameter gradually decreases from the upper part toward the lower part, and the flow path forming first member 11 and the flow path forming second member 12 have such a shape. The channel forming third member 13 that can form the second channel 114 may have a shape corresponding to the channel forming first member 11. The same applies to the heat exchangers of other embodiments described later.
　また、被熱交換液体１１０はミルクに限るものではなく、飲料用の液体など、任意の液体であればよい。また、熱交換用液体１３０も水に限るものではなく、任意の液体であればよい。さらに、熱交換用液体１３０に代えて、熱交換用流体として任意の気体を用いてもよい。 Further, the heat exchange liquid 110 is not limited to milk, and may be any liquid such as a beverage liquid. Further, the heat exchange liquid 130 is not limited to water, and may be any liquid. Furthermore, instead of the heat exchange liquid 130, any gas may be used as the heat exchange fluid.
　また、熱交換用液体１３０には、飲用に適した水道水を用いることが好ましい。熱交換器１では、熱交換用液体１３０は、熱交換用液体１３０等の、人の口に直接触れるものと接触することがない。しかしながら、熱交換器１の洗浄時などに、熱交換用液体１３０の第１流路１３４から被熱交換液体１１０の第２流路１１４へと雑菌等が移動する可能性がある。したがって、熱交換用液体１３０は、衛生上に問題のないものを用いることが好ましい。 Moreover, it is preferable to use tap water suitable for drinking as the heat exchange liquid 130. In the heat exchanger 1, the heat exchange liquid 130 does not come into contact with anything that directly touches the human mouth, such as the heat exchange liquid 130. However, when the heat exchanger 1 is washed, miscellaneous bacteria and the like may move from the first flow path 134 of the heat exchange liquid 130 to the second flow path 114 of the heat exchange liquid 110. Therefore, it is preferable to use a heat exchange liquid 130 that does not have a sanitary problem.
　また、以上の例では、熱交換器１は、被熱交換液体１１０を熱交換用液体１３０にて冷却するものとして説明したが、熱交換用液体１３０によって被熱交換液体１１０を加熱するものであってもよい。 In the above example, the heat exchanger 1 is described as cooling the heat exchange liquid 110 with the heat exchange liquid 130, but the heat exchange liquid 110 is heated by the heat exchange liquid 130. There may be.
　〔実施の形態２〕
　本発明の他の実施の形態を図面に基づいて以下に説明する。図７は、本発明の実施の形態の熱交換器２０１の縦断面を含む斜視図である。 [Embodiment 2]
Another embodiment of the present invention will be described below with reference to the drawings. FIG. 7 is a perspective view including a longitudinal section of the heat exchanger 201 according to the embodiment of the present invention.
　熱交換器２０１は、図４に示した熱交換器１の流路形成第２部材１２に代えて、流路形成第２部材２１１を備えている。流路形成第２部材２１１は、流路形成第２部材１２と同様、円錐部１２１の外周面（側面）に断面が例えばＶ字形の螺旋溝２１２が上部から下部に形成されている。ただし、螺旋溝２１２は、上部から下部に向かって、漸次溝の幅が広くかつ溝の深さが深くなっている。 The heat exchanger 201 includes a flow path forming second member 211 instead of the flow path forming second member 12 of the heat exchanger 1 shown in FIG. Similar to the flow path forming second member 12, the flow path forming second member 211 has a spiral groove 212 having a V-shaped cross section formed on the outer peripheral surface (side surface) of the conical portion 121 from the upper part to the lower part. However, in the spiral groove 212, the width of the groove gradually increases and the depth of the groove increases from the top to the bottom.
　円錐部１２１の外周面に螺旋溝２１２が形成されていることにより、流路形成第１部材１１の内面に流路形成第２部材２１１を配置した場合に、流路形成第１部材１１の内面と流路形成第２部材２１１の外面との間に、被熱交換液体１１０が流れる螺旋状の第２流路２１３が形成される。ただし、第２流路２１３は、上記のように螺旋溝２１２が形成されていることにより、１周分の流路長が長い上流側（上部）から、１周分の流路長が漸次短くなる下流側（下部）に向かって、流路の大きさ（流路における被熱交換液体１１０の許容流量）が漸次大きくなっている。 By forming the spiral groove 212 on the outer peripheral surface of the conical part 121, the inner surface of the flow path forming first member 11 can be obtained when the flow path forming second member 211 is disposed on the inner surface of the flow path forming first member 11. And a spiral second channel 213 through which the heat exchange liquid 110 flows is formed between the second channel 211 and the outer surface of the channel forming second member 211. However, the second channel 213 has the spiral groove 212 formed as described above, so that the channel length for one round is gradually shorter from the upstream side (upper part) where the channel length for one cycle is long. The size of the flow path (allowable flow rate of the heat exchange liquid 110 in the flow path) gradually increases toward the downstream side (lower part).
　流路形成第２部材２１１および熱交換器２０１の他の構成は、流路形成第２部材１２および熱交換器１と同様である。 Other configurations of the flow path forming second member 211 and the heat exchanger 201 are the same as those of the flow path forming second member 12 and the heat exchanger 1.
　上記の構成において、熱交換器２０１では、供給された被熱交換液体１１０の量が排出口１７から排出可能な量を超えた場合、超えた分の被熱交換液体１１０が熱交換器２０１の下部に溜っていくことになる。この点は前記熱交換器１においても同様である。 In the above configuration, in the heat exchanger 201, when the amount of the supplied heat exchange liquid 110 exceeds the amount that can be discharged from the discharge port 17, the excess heat exchange liquid 110 is stored in the heat exchanger 201. It will accumulate at the bottom. This also applies to the heat exchanger 1.
　ここで、第２流路２１３における熱交換器２０１の下方側の部分の大きさが小さいままであれば、被熱交換液体１１０の液面が第２流路２１３の上方側まで上がってくる事態が生じ易い。この場合、第２流路２１３の実質的な流路長が短くなって熱交換器２０１での熱交換効率が低下する。 Here, if the size of the lower portion of the heat exchanger 201 in the second flow path 213 remains small, the liquid level of the heat exchange liquid 110 rises to the upper side of the second flow path 213. Is likely to occur. In this case, the substantial flow path length of the 2nd flow path 213 becomes short, and the heat exchange efficiency in the heat exchanger 201 falls.
　これに対し、熱交換器２０１では、第２流路２１３の大きさ（流路における被熱交換液体１１０の許容流量）が上流側から下流側に向かってが漸次大きくなっている。したがって、第２流路２１３は、下流側において被熱交換液体１１０を保持できる量が増加するため、被熱交換液体１１０の液面が上昇し難くなる。この結果、第２流路２１３における被熱交換液体１１０の流路長を確保することができ、熱交換効率の低下を抑制することができる。 In contrast, in the heat exchanger 201, the size of the second flow path 213 (allowable flow rate of the heat exchange liquid 110 in the flow path) gradually increases from the upstream side toward the downstream side. Therefore, the amount of the second flow path 213 that can hold the heat exchange liquid 110 on the downstream side increases, and therefore the liquid level of the heat exchange liquid 110 is unlikely to rise. As a result, the channel length of the heat exchange liquid 110 in the second channel 213 can be ensured, and a decrease in heat exchange efficiency can be suppressed.
　〔実施の形態３〕
　本発明のさらに他の実施の形態を図面に基づいて以下に説明する。図８は、本発明の実施の形態の熱交換器２０２の縦断面を含む斜視図である。 [Embodiment 3]
Still another embodiment of the present invention will be described below with reference to the drawings. FIG. 8 is a perspective view including a longitudinal section of the heat exchanger 202 according to the embodiment of the present invention.
　熱交換器２０２は、図４に示した熱交換器１の流路形成第２部材１２に代えて、流路形成第２部材２２１を備えている。流路形成第２部材２２１は、下端部に下端開口部２２２が形成されている。 The heat exchanger 202 includes a flow path forming second member 221 instead of the flow path forming second member 12 of the heat exchanger 1 shown in FIG. The flow path forming second member 221 has a lower end opening 222 formed at the lower end.
　流路形成第２部材２２１および熱交換器２０２の他の構成は、流路形成第２部材１２および熱交換器１と同様である。 Other configurations of the flow path forming second member 221 and the heat exchanger 202 are the same as those of the flow path forming second member 12 and the heat exchanger 1.
　上記の構成において、熱交換器２０２では、供給された被熱交換液体１１０の量が排出口１７から排出可能な量を超えた場合、超えた分の被熱交換液体１１０が熱交換器２０２の下部に溜っていくことになる。この点は前記熱交換器１においても同様である。 In the above configuration, in the heat exchanger 202, when the amount of the supplied heat exchange liquid 110 exceeds the amount that can be discharged from the discharge port 17, the excess heat exchange liquid 110 is stored in the heat exchanger 202. It will accumulate at the bottom. This also applies to the heat exchanger 1.
　ここで、流路形成第２部材２２１に下端開口部２２２が形成されていない場合、被熱交換液体１１０の液面が第２流路１１４の上方側まで上がってくる事態が生じ易い。この場合、第２流路１１４の実質的な流路長が短くなって熱交換器２０２での熱交換効率が低下する。 Here, when the lower end opening 222 is not formed in the flow path forming second member 221, a situation in which the liquid level of the heat exchange liquid 110 rises to the upper side of the second flow path 114 is likely to occur. In this case, the substantial flow path length of the 2nd flow path 114 becomes short, and the heat exchange efficiency in the heat exchanger 202 falls.
　これに対し、熱交換器２０２では、流路形成第２部材２２１の下端部に下端開口部２２２が形成されている。したがって、排出口１７から排出可能な量を超えた分の被熱交換液体１１０は、下端開口部２２２から流路形成第２部材２２１の内側の領域に流入することができ、第２流路１１４では被熱交換液体１１０の液面が上昇し難くなる。この結果、第２流路１１４における被熱交換液体１１０の流路長を確保することができ、熱交換効率の低下を抑制することができる。 In contrast, in the heat exchanger 202, a lower end opening 222 is formed at the lower end of the flow path forming second member 221. Therefore, the amount of the heat exchange liquid 110 that exceeds the amount that can be discharged from the discharge port 17 can flow into the region inside the flow path forming second member 221 from the lower end opening 222, and the second flow path 114. Then, the liquid level of the heat exchange liquid 110 becomes difficult to rise. As a result, the channel length of the heat exchange liquid 110 in the second channel 114 can be ensured, and a decrease in heat exchange efficiency can be suppressed.
　なお、本実施の形態の構成は、熱交換器１（図４参照）だけでなく、熱交換器２０１（図７参照）に対しても当然に適用可能である。 Note that the configuration of the present embodiment is naturally applicable not only to the heat exchanger 1 (see FIG. 4) but also to the heat exchanger 201 (see FIG. 7).
　〔実施の形態４〕
　本発明のさらに他の実施の形態について以下に説明する。 [Embodiment 4]
Still another embodiment of the present invention will be described below.
　図４に示した熱交換器１では、流路形成第２部材１２は容器形状となっている。このような構成は、熱交換器１の軽量化、製造の容易化、材料費の低減において好ましい。しかしながら、流路形成第２部材１２は、容器形状に限定されない。 In the heat exchanger 1 shown in FIG. 4, the flow path forming second member 12 has a container shape. Such a configuration is preferable for reducing the weight of the heat exchanger 1, facilitating manufacturing, and reducing material costs. However, the flow path forming second member 12 is not limited to the container shape.
　例えば、流路形成第２部材１２は、円錐部１２１の上面が閉じた構造であってもよい。あるいは、流路形成第２部材１２は、円錐部１２１の内側に部材の詰まった構造（内側が空洞ではない構造）であってもよい。すなわち、流路形成第２部材１２は、流路形成第１部材１１と共に流路形成第１部材１１を形成し、かつ第２流路１１４の洗浄、消毒、および状態確認が容易であるように、流路形成第１部材１１に対して容易に取り外し可能なものであればよい。 For example, the flow path forming second member 12 may have a structure in which the upper surface of the conical portion 121 is closed. Alternatively, the flow path forming second member 12 may have a structure in which members are packed inside the conical portion 121 (a structure in which the inside is not a cavity). That is, the flow path forming second member 12 forms the flow path forming first member 11 together with the flow path forming first member 11, and the second flow path 114 can be easily cleaned, disinfected, and checked. Any material that can be easily removed from the flow path forming first member 11 may be used.
　上記の構成は、他の熱交換器２０１，２０２においても同様に適用可能である。なお、流路形成第２部材２２１の下端部に下端開口部２２２が形成されている熱交換器２０２については、流路形成第２部材２２１の円錐部１２１の内側上部のみが部材の詰まった構造（内側上部のみが空洞ではない構造）とするのが好ましい。 The above configuration can be similarly applied to the other heat exchangers 201 and 202. In addition, about the heat exchanger 202 in which the lower end opening part 222 is formed in the lower end part of the flow path formation 2nd member 221, only the inner upper part of the cone part 121 of the flow path formation 2nd member 221 is the structure where the member was clogged. (Structure in which only the inner upper part is not hollow) is preferable.
　〔実施の形態５〕
　本発明のさらに他の実施の形態について以下に説明する。 [Embodiment 5]
Still another embodiment of the present invention will be described below.
　図４に示した熱交換器１は、流路形成第１～第３部材１１～１３を備えた構成に限定されない。 The heat exchanger 1 shown in FIG. 4 is not limited to the configuration including the flow path forming first to third members 11 to 13.
　例えば、熱交換器１は、流路形成第１部材１１および流路形成第３部材１３に代えて、これら流路形成第１部材１１および流路形成第３部材１３が一体となった第１の流路形成部材を備えたものであってもよい。 For example, in the heat exchanger 1, instead of the flow path forming first member 11 and the flow path forming third member 13, the first flow path forming first member 11 and the flow path forming third member 13 are integrated. The flow path forming member may be provided.
　すなわち、流路形成第１部材１１および流路形成第３部材１３に代えて、容器形状の第１の流路形成部材を備え、この第１の流路形成部材の周壁内に第１流路１３４が形成され、流路形成部材の内面に流路形成第２部材１２が取り外し可能に配置され、第１の流路形成部材と流路形成第２部材（第２の流路形成部材）１２との間に第２流路１１４が形成されている構成であってもよい。上記の構成は、他の熱交換器２０１，２０２においても同様に適用可能である。 That is, instead of the flow path forming first member 11 and the flow path forming third member 13, a container-shaped first flow path forming member is provided, and the first flow path is formed in the peripheral wall of the first flow path forming member. 134 is formed, the flow path forming second member 12 is detachably disposed on the inner surface of the flow path forming member, and the first flow path forming member and the flow path forming second member (second flow path forming member) 12 are disposed. The 2nd flow path 114 may be formed between these. The above configuration can be similarly applied to the other heat exchangers 201 and 202.
　〔変形例１〕
　上述した各実施の形態では、第２流路１１４を被熱交換液体１１０の流路とし、第１流路１３４を熱交換用液体１３０の流路としているが、これに限定されない。すなわち、第２流路１１４を熱交換用液体１３０の流路とし、第１流路を被熱交換液体１１０の流路としてもよい。 [Modification 1]
In each of the embodiments described above, the second flow path 114 is used as the flow path for the heat exchange liquid 110 and the first flow path 134 is used as the flow path for the heat exchange liquid 130. However, the present invention is not limited to this. That is, the second flow path 114 may be the flow path of the heat exchange liquid 130 and the first flow path may be the flow path of the heat exchange liquid 110.
　〔変形例２〕
　次に、図１に示した熱交換システムの変形例について説明する。図９は、熱交換システム１００の変形例に係る熱交換システム１０１の構成を示す模式図である。図９に示す熱交換システム１０１は、図１に示す熱交換システム１００とは異なり、タンク２に補助冷却機構６が設置されている。補助冷却機構６は、ファンによる空冷機構、ペルチェ素子による冷却機構、またはフィンを備えた放熱機構等である。 [Modification 2]
Next, a modification of the heat exchange system shown in FIG. 1 will be described. FIG. 9 is a schematic diagram illustrating a configuration of a heat exchange system 101 according to a modification of the heat exchange system 100. A heat exchange system 101 shown in FIG. 9 is different from the heat exchange system 100 shown in FIG. 1 in that an auxiliary cooling mechanism 6 is installed in the tank 2. The auxiliary cooling mechanism 6 is an air cooling mechanism using a fan, a cooling mechanism using a Peltier element, a heat dissipation mechanism including fins, or the like.
　熱交換用液体１３０によって被熱交換液体１１０を冷却する場合、熱交換用液体１３０は被熱交換液体１１０との熱交換によって温度が上昇していく。特に被熱交換液体１１０の量（熱交換用液体１３０に対する相対的な量）が多かったり、被熱交換液体１１０の温度が非常に高いものであったりした場合、熱交換用液体１３０の温度上昇は大きくなる。熱交換用液体１３０の温度が上昇すると、被熱交換液体１１０との温度差が小さくなり、熱交換量が低下する。 When the heat exchange liquid 110 is cooled by the heat exchange liquid 130, the temperature of the heat exchange liquid 130 increases due to heat exchange with the heat exchange liquid 110. In particular, when the amount of the heat exchange liquid 110 is large (relative to the heat exchange liquid 130) or the temperature of the heat exchange liquid 110 is very high, the temperature of the heat exchange liquid 130 increases. Will grow. When the temperature of the heat exchange liquid 130 rises, the temperature difference from the heat exchange liquid 110 becomes smaller, and the amount of heat exchange decreases.
　そこで、補助冷却機構６によりタンク２に貯蔵されている熱交換用液体１３０を冷却すれば、熱交換によって上昇した熱交換用液体１３０の温度を効率よく低下させることができる。これにより、熱交換用液体１３０の温度を低温に維持することができ、熱交換量の低下を抑制することができる。さらに、タンク２に貯蔵する冷却用水としての熱交換用液体１３０の量を少なくすることも可能となる。 Therefore, if the heat exchange liquid 130 stored in the tank 2 is cooled by the auxiliary cooling mechanism 6, the temperature of the heat exchange liquid 130 that has risen due to the heat exchange can be efficiently reduced. Thereby, the temperature of the heat exchange liquid 130 can be maintained at a low temperature, and a decrease in the heat exchange amount can be suppressed. Furthermore, the amount of the heat exchange liquid 130 as cooling water stored in the tank 2 can be reduced.
　〔変形例３〕
　次に、図１に示した熱交換システムの他の変形例について説明する。図１０は、熱交換システム１００の他の変形例に係る熱交換システム１０２の構成を示す模式図である。図１０に示す熱交換システム１０２は、図１に示す熱交換システム１００とは異なり、タンク２にヒーター７が設置されている。この場合の熱交換システム１０２は、高温の熱交換用液体１３０を用いて、低温の被熱交換液体１１０を温めるものである。 [Modification 3]
Next, another modification of the heat exchange system shown in FIG. 1 will be described. FIG. 10 is a schematic diagram illustrating a configuration of a heat exchange system 102 according to another modification of the heat exchange system 100. A heat exchanging system 102 shown in FIG. 10 is different from the heat exchanging system 100 shown in FIG. The heat exchange system 102 in this case warms the low-temperature heat exchange liquid 110 using the high-temperature heat exchange liquid 130.
　冷蔵庫等で保管され、冷えている飲料液体の加温方法としては電子レンジによる加熱が一般的である。しかしながら、電子レンジによる加熱は、不均一であり、局所的に熱いホットスポットができてしまうことが知られている。このようなホットスポットを避けたい場合、例えば、調乳後ミルクを再加温する場合などに、熱交換システム１０２による加温が適している。 Refrigerating liquid stored in a refrigerator or the like is generally heated by a microwave oven. However, it is known that heating by a microwave oven is non-uniform and a hot hot spot is locally generated. When it is desired to avoid such a hot spot, for example, when reheating the milk after milk preparation, heating by the heat exchange system 102 is suitable.
　以上のように、各例に示した熱交換器は、被熱交換液体の温度調整（特に調乳後のミルクの冷却）を、衛生的にかつ、短時間で適当な温度まで調整することができる。さらに、熱交換器が単純な構造であるため、安価に製造することもできる。また、衛生的な飲料の冷却および加温、特に、調乳後の高温ミルクの適温への冷却が可能となる。このため、調乳後に必要であった哺乳瓶を水道水等で冷却する煩わしい作業が不要となり、育児に対しての苦労を軽減することが可能となる。 As described above, the heat exchanger shown in each example can adjust the temperature of the heat exchange liquid (particularly cooling the milk after milk preparation) to an appropriate temperature in a sanitary manner in a short time. it can. Furthermore, since the heat exchanger has a simple structure, it can be manufactured at low cost. In addition, it is possible to cool and warm hygienic beverages, in particular, to cool hot milk after preparation to an appropriate temperature. For this reason, the troublesome operation | work which cools the baby bottle required after milk preparation with a tap water etc. becomes unnecessary, and it becomes possible to reduce the difficulty with respect to child care.
　〔まとめ〕
　本発明の態様１に係る熱交換器は、容器形状を有する第１の流路形成部材（流路形成第１部材１１、流路形成第３部材１３）と、前記第１の流路形成部材の内側に、前記第１の流路形成部材に対して取り外し可能に配置された第２の流路形部材（流路形成第２部材１２，２１１，２２１）とを備え、前記第１の流路形成部材は、容器形状の周壁部の内周面の径が上部から下部に向かって漸次小さくなり、かつ熱交換用液体１３０を流す第１流路１３４が前記周壁部内に形成され、前記第１の流路形成部材の前記内周面と前記第２の流路形成部材の外周面との間には、これら内周面と外周面とによって前記熱交換用液体１３０と熱交換される被熱交換液体１１０を流す螺旋状の第２流路１１４が形成されている。 [Summary]
The heat exchanger according to the first aspect of the present invention includes a first flow path forming member (a flow path forming first member 11 and a flow path forming third member 13) having a container shape, and the first flow path forming member. And a second flow path-shaped member (flow path forming second members 12, 211, 221) disposed detachably with respect to the first flow path forming member. The path forming member has a diameter of the inner peripheral surface of the container-shaped peripheral wall portion that gradually decreases from the top to the bottom, and a first flow path 134 through which the heat exchange liquid 130 flows is formed in the peripheral wall portion. Between the inner peripheral surface of the first flow path forming member and the outer peripheral surface of the second flow path forming member, the heat exchange liquid 130 is exchanged by the inner peripheral surface and the outer peripheral surface. A spiral second flow path 114 through which the heat exchange liquid 110 flows is formed.
　上記の構成によれば、第１の流路形成部材は容器形状の周壁部の内周面の径が上部から下部に向かって漸次小さくなっているので、第１の流路形成部材の内側に第２の流路形部材を配置することにより、第１の流路形成部材の内周面と第２の流路形成部材の外周面との間に螺旋状の第２流路１１４を容易に形成することができる。また、このようにして形成される第２流路１１４は、１周分の径が上部（上流側）から下部（下流側）に向かって漸次小さくなっている。 According to the above configuration, since the diameter of the inner peripheral surface of the container-shaped peripheral wall portion of the first flow path forming member gradually decreases from the upper part toward the lower part, the first flow path forming member is disposed inside the first flow path forming member. By arranging the second flow path shape member, the spiral second flow path 114 can be easily formed between the inner peripheral surface of the first flow path forming member and the outer peripheral surface of the second flow path forming member. Can be formed. In addition, the second flow path 114 formed in this way has a diameter that gradually decreases from the upper part (upstream side) to the lower part (downstream side).
　また、第２流路１１４は螺旋状に形成されて流路長が長くなっているので、第２流路１１４を流れる被熱交換液体１１０と第１流路１３４を流れる熱交換用液体１３０との熱交換効率が良好となる。 Further, since the second flow path 114 is formed in a spiral shape and has a long flow path length, the heat exchange liquid 110 that flows through the second flow path 114 and the heat exchange liquid 130 that flows through the first flow path 134 The heat exchange efficiency is improved.
　また、第２の流路形部材は、第１の流路形成部材に対して取り外し可能に配置されているので、第２の流路形部材を取り外すことにより、第２流路１１４の洗浄、消毒および状態確認を容易に行うことができる。 In addition, since the second flow path member is detachably disposed with respect to the first flow path forming member, the second flow path member can be removed by washing the second flow path 114, Disinfection and status check can be easily performed.
　本発明の態様２に係る熱交換器は、上記態様１において、前記第１の流路形成部材（流路形成第１部材１１、流路形成第３部材１３）は、前記第２流路１１４から前記被熱交換液体１１０を排出する排出口１７が下端部に形成され、前記第２の流路形成部材（流路形成第２部材１２）は、容器形状を有し、下端部に開口部（下端開口部２２２）が形成されている。 In the heat exchanger according to aspect 2 of the present invention, in the above aspect 1, the first flow path forming member (the flow path forming first member 11 and the flow path forming third member 13) is the second flow path 114. A discharge port 17 for discharging the heat exchange liquid 110 from the bottom is formed at the lower end, and the second flow path forming member (flow path forming second member 12) has a container shape and has an opening at the lower end. (Lower end opening 222) is formed.
　上記の構成によれば、熱交換器２０２では、供給された被熱交換液体１１０の量が排出口１７から排出可能な量を超えた場合、超えた分の被熱交換液体１１０が熱交換器２０２の下部に溜っていくことになる。 According to the above configuration, in the heat exchanger 202, when the amount of the supplied heat exchange liquid 110 exceeds the amount that can be discharged from the discharge port 17, the excess heat exchange liquid 110 is transferred to the heat exchanger. It will accumulate in the lower part of 202.
　ここで、第２の流路形成部材の下端部に開口部が形成されていない場合、被熱交換液体１１０の液面が第２流路１１４の上部側（上流側）まで上がってくる事態が生じ易い。この場合、第２流路１１４の実質的な流路長が短くなって熱交換器２０２での熱交換効率が低下する。 Here, when the opening is not formed at the lower end of the second flow path forming member, the liquid level of the heat exchange liquid 110 may rise to the upper side (upstream side) of the second flow path 114. It is likely to occur. In this case, the substantial flow path length of the 2nd flow path 114 becomes short, and the heat exchange efficiency in the heat exchanger 202 falls.
　これに対し、熱交換器２０２では、第２の流路形成部材の下端部に開口部が形成されている。したがって、排出口１７から排出可能な量を超えた分の被熱交換液体１１０は、第２の流路形成部材の開口部から第２の流路形成部材の内側の領域に流入することができ、第２流路１１４では被熱交換液体１１０の液面が上昇し難くなる。この結果、第２流路１１４における被熱交換液体１１０の流路長を確保することができ、熱交換効率の低下を抑制することができる。 In contrast, in the heat exchanger 202, an opening is formed at the lower end of the second flow path forming member. Therefore, the heat exchange liquid 110 that exceeds the amount that can be discharged from the discharge port 17 can flow into the region inside the second flow path forming member from the opening of the second flow path forming member. In the second flow path 114, the liquid level of the heat exchange liquid 110 is difficult to rise. As a result, the channel length of the heat exchange liquid 110 in the second channel 114 can be ensured, and a decrease in heat exchange efficiency can be suppressed.
　本発明の態様３に係る熱交換器は、上記態様１または２において、前記第１の流路形成部材は、流路形成内側部材（流路形成第１部材１１）と流路形成外側部材（流路形成第３部材１３）とを備え、前記流路形成内側部材の外周面と前記流路形成外側部材の内周面との間には、これら内周面と外周面とによって前記第１流路１３４が形成され、前記流路形成内側部材の内周面と前記第２の流路形成部材（流路形成第２部材１２）の外周面との間には、これら内周面と外周面とによって前記第２流路１１４が形成されている。 In the heat exchanger according to aspect 3 of the present invention, in the above aspect 1 or 2, the first flow path forming member includes a flow path forming inner member (flow path forming first member 11) and a flow path forming outer member ( A flow path forming third member 13) between the outer peripheral surface of the flow path forming inner member and the inner peripheral surface of the flow path forming outer member by the inner peripheral surface and the outer peripheral surface. A flow path 134 is formed, and between the inner peripheral surface of the flow path forming inner member and the outer peripheral surface of the second flow path forming member (flow path forming second member 12), these inner peripheral surface and outer periphery The second flow path 114 is formed by the surface.
　上記の構成によれば、第１の流路形成部材は、第２流路１１４を形成する流路形成内側部材と流路形成外側部材とを備えているので、流路形成内側部材を、例えば熱伝導率の高い薄板の金属板をプレス成型することにより形成することができる。この場合には、流路形成内側部材の材料として、安価かつ第２流路１１４の消毒薬に対して耐食性のある金属材料を使用することができる。また、この場合には、第２流路１１４の被熱交換液体１１０と第１流路１３４の熱交換用液体１３０との熱交換効率を向上させることができる。 According to the above configuration, the first flow path forming member includes the flow path forming inner member and the flow path forming outer member that form the second flow path 114. It can be formed by press molding a thin metal plate having high thermal conductivity. In this case, a metal material that is inexpensive and has corrosion resistance to the disinfectant in the second flow path 114 can be used as the material for the flow path forming inner member. In this case, the heat exchange efficiency between the heat exchange liquid 110 in the second flow path 114 and the heat exchange liquid 130 in the first flow path 134 can be improved.
　本発明の態様４に係る熱交換器は、上記態様１から３のいずれかの態様において、前記第１の流路形成部材（流路形成第１部材１１、流路形成第３部材１３）は、前記第２流路２１３から前記被熱交換液体１１０を排出する排出口１７が下端部に形成され、前記第２流路２１３は、上部から下部に向かって流路の大きさが漸次大きくなっている。 The heat exchanger according to aspect 4 of the present invention is the heat exchanger according to any one of the aspects 1 to 3, wherein the first flow path forming member (the flow path forming first member 11 and the flow path forming third member 13) is A discharge port 17 for discharging the heat exchange liquid 110 from the second channel 213 is formed at the lower end, and the size of the channel of the second channel 213 gradually increases from the top to the bottom. ing.
　上記の構成によれば、熱交換器２０１では、第２流路２１３に供給された被熱交換液体１１０の量が排出口１７から排出可能な量を超えた場合、超えた分の被熱交換液体１１０が熱交換器の下部に溜っていくことになる。 According to the above configuration, in the heat exchanger 201, when the amount of the heat exchange liquid 110 supplied to the second flow path 213 exceeds the amount that can be discharged from the discharge port 17, the excess heat exchange is performed. The liquid 110 accumulates in the lower part of the heat exchanger.
　ここで、第２流路２１３における熱交換器２０１の下部側（下流側）の部分の大きさいが小さいままであれば、被熱交換液体１１０の液面が第２流路２１３の上部側（上流側）まで上がってくる事態が生じ易い。この場合、第２流路２１３の実質的な流路長が短くなって熱交換器での熱交換効率が低下する。 Here, if the size of the lower side (downstream side) of the heat exchanger 201 in the second flow path 213 remains small, the liquid surface of the heat exchange liquid 110 is on the upper side of the second flow path 213 ( It is easy to get up to the upstream). In this case, the substantial flow path length of the 2nd flow path 213 becomes short, and the heat exchange efficiency in a heat exchanger falls.
　これに対し、熱交換器２０１では、第２流路２１３の大きさが上部（上流側）から下部（下流側）に向かってが漸次大きくなっている。したがって、第２流路２１３は、下流側において被熱交換液体１１０を保持できる量が増加するため、被熱交換液体１１０の液面が上昇し難くなる。この結果、第２流路２１３における被熱交換液体１１０の流路長を確保することができ、熱交換効率の低下を抑制することができる。 In contrast, in the heat exchanger 201, the size of the second flow path 213 gradually increases from the upper part (upstream side) to the lower part (downstream side). Therefore, the amount of the second flow path 213 that can hold the heat exchange liquid 110 on the downstream side increases, and therefore the liquid level of the heat exchange liquid 110 is unlikely to rise. As a result, the channel length of the heat exchange liquid 110 in the second channel 213 can be ensured, and a decrease in heat exchange efficiency can be suppressed.
　本発明の態様５に係る熱交換器は、態様１から４のいずれかの態様の熱交換器１，２０１，２０２と、前記熱交換用液体１３０を貯蔵する貯蔵部（タンク２）と、前記熱交換用液体１３０を前記貯蔵部から前記熱交換器１，２０１，２０２に供給する供給部（ポンプ３）とを備えている。 A heat exchanger according to Aspect 5 of the present invention is a heat exchanger 1, 201, 202 according to any one of Aspects 1 to 4, a storage unit (tank 2) for storing the heat exchange liquid 130, and A supply unit (pump 3) for supplying the heat exchange liquid 130 from the storage unit to the heat exchangers 1, 201, 202;
　上記の構成によれば、熱交換効率が良好であり、熱交換器１，２０１，２０２の第２流路１１４，２１３の洗浄、消毒および状態確認が容易である熱交換システムを提供することができる。 According to the above configuration, it is possible to provide a heat exchange system that has good heat exchange efficiency and that can easily clean, disinfect, and check the state of the second flow paths 114, 213 of the heat exchangers 1, 201, 202. it can.
