図１に示すように、保冷庫１０は、冷凍機ユニット１１上に保冷庫本体１６が配置される。冷凍機ユニット１１の下面四隅には、自在キャスター２２が取り付けられており、保冷庫１０を容易に移動させることができる。 As shown in FIG. 1, the cool box 10 has a cool box body 16 disposed on a refrigerator unit 11. Free casters 22 are attached to the four corners of the lower surface of the refrigerator unit 11 so that the cool box 10 can be easily moved.

保冷庫本体１６は、断熱箱体によって囲まれた直方体の保冷室１６ｂを庫内に形成している。保冷室１６ｂは、天壁部１６ｃ、背壁部１６ｄ、左右の側壁部１６ｅ，１６ｅ、及び底壁部１６ｆによって画成されている。保冷室１６ｂは、壁部が設けられていない前面開口１６ａが開閉扉１８で開閉され、この前面開口１６ａから物品が出し入れされる。 The cool box main body 16 forms a rectangular parallelepiped cool box 16b surrounded by a heat insulating box. The cold insulation chamber 16b is defined by a top wall portion 16c, a back wall portion 16d, left and right side wall portions 16e and 16e, and a bottom wall portion 16f. In the cold insulation chamber 16b, a front opening 16a that is not provided with a wall portion is opened and closed by an opening / closing door 18, and articles are taken in and out from the front opening 16a.

図２に示すように、背壁部１６ｄには、庫外側（外側）から庫内側（内側）に向かって順に、断熱部材としての真空断熱材３４、断熱機能を有する発泡樹脂３３あるいは硬質の発砲樹脂であるスペーサ３２、押圧平板３１が配置される。押圧平板３１の内側に蓄冷部２０が配置される。 As shown in FIG. 2, the back wall portion 16 d has a vacuum heat insulating material 34 as a heat insulating member, a foamed resin 33 having a heat insulating function, or a hard foam in order from the outer side (outer side) to the inner side (inner side). A spacer 32 made of resin and a pressing plate 31 are arranged. The cold storage unit 20 is disposed inside the pressing flat plate 31.

蓄冷部２０は、押圧平板３１側で、伝熱シート１４を介して蒸発器配管１５が埋め込まれた蓄冷材１３が配置される。さらに蓄冷材１３の内側には、伝熱板１２が蓄冷材１３に密着して配置され、一面が保冷室１６ｂに露出している。 In the cold storage unit 20, the cold storage material 13 in which the evaporator pipe 15 is embedded via the heat transfer sheet 14 is arranged on the pressing plate 31 side. Furthermore, the heat transfer plate 12 is disposed in close contact with the cold storage material 13 inside the cold storage material 13, and one surface is exposed to the cold insulation chamber 16b.

背壁部１６ｄの端部には、伝熱板１２と真空断熱材３４とを固定する断熱部材３５が配置される。 A heat insulating member 35 that fixes the heat transfer plate 12 and the vacuum heat insulating material 34 is disposed at the end of the back wall portion 16d.

蒸発器配管１５は、冷凍機ユニット１１の冷凍回路に配管接続される。図示しない冷凍回路は、冷凍サイクルのうちの蒸発器以外のポンプ、凝縮器などを有するとともに、制御部を有する。制御部は、保冷室１６ｂ内に設けた図示しない温度センサが検出する温度をもとに、ポンプなどの冷凍回路を駆動して蓄冷材１３を冷却する保冷制御を行う。 The evaporator pipe 15 is connected by piping to the refrigeration circuit of the refrigerator unit 11. A refrigeration circuit (not shown) includes a pump, a condenser, and the like other than the evaporator in the refrigeration cycle, and a control unit. The control unit performs cold insulation control for driving the refrigeration circuit such as a pump to cool the cold storage material 13 based on a temperature detected by a temperature sensor (not shown) provided in the cold insulation chamber 16b.

すなわち、蒸発器配管１５内に冷却された冷媒が流れると、伝熱シート１４を介して蓄冷材１３が冷却される。そして、蓄冷材１３は、伝熱板１２を介して保冷室１６ｂを冷却する。なお、蓄冷材１３の外側は、断熱材で形成されているため、主として、蓄冷材１３の吸熱は保冷室１６ｂ側に対して行われることになる。 That is, when the cooled refrigerant flows into the evaporator pipe 15, the cool storage material 13 is cooled via the heat transfer sheet 14. The cold storage material 13 cools the cold insulation chamber 16 b through the heat transfer plate 12. In addition, since the outer side of the cool storage material 13 is formed with the heat insulating material, the heat absorption of the cool storage material 13 is mainly performed with respect to the cold storage chamber 16b side.

なお、蓄冷部２０は、天壁部１６ｃ、背壁部１６ｄ、左右の側壁部１６ｅ，１６ｅの内側に設けられる。なお、蓄冷部２０は、天壁部１６ｃ、背壁部１６ｄのみに設けても良い。蓄冷部２０は、天壁部１６ｃ、背壁部１６ｄ、左右の側壁部１６ｅ，１６ｅの内の１以上の内側に設けてよい。なお、その他の底壁部１６ｆ、開閉扉１８は、蓄冷部２０の配置に替えて、真空断熱材を配置することが好ましい。 In addition, the cool storage part 20 is provided inside the top wall part 16c, the back wall part 16d, and the left and right side wall parts 16e and 16e. In addition, you may provide the cool storage part 20 only in the top wall part 16c and the back wall part 16d. The cold storage part 20 may be provided inside one or more of the top wall part 16c, the back wall part 16d, and the left and right side wall parts 16e, 16e. In addition, it is preferable to arrange | position a vacuum heat insulating material instead of arrangement | positioning of the cool storage part 20 for the other bottom wall part 16f and the door 18.

上述した伝熱板１２は、例えばアルミニウムで形成される。蓄冷材１３は、例えば、ポリエチレンの袋に水及びゲル化剤等を封入した公知のものを用いればよい。伝熱シート１４は、例えば、アクリル系熱伝導シートである。蒸発器配管１５は、例えば、銅管である。押圧平板３１は、例えば、プラスチック板であり、具体的には硬質のポリ塩化ビニル板である。スペーサ３２及び断熱部材３５は、例えば、硬質の発泡ポリエチレンである。真空断熱材３４は、例えば、芯材をラミネートフィルムによって被覆し、内部を真空状態に減圧して封止した公知のものを用いればよい。発泡樹脂３３は、例えば、発泡ウレタンである。 The heat transfer plate 12 described above is made of, for example, aluminum. As the cold storage material 13, for example, a known material in which water and a gelling agent are sealed in a polyethylene bag may be used. The heat transfer sheet 14 is, for example, an acrylic heat conductive sheet. The evaporator pipe 15 is, for example, a copper pipe. The pressing flat plate 31 is, for example, a plastic plate, specifically, a hard polyvinyl chloride plate. The spacer 32 and the heat insulating member 35 are, for example, hard foamed polyethylene. As the vacuum heat insulating material 34, for example, a known material in which a core material is covered with a laminate film and the inside is reduced in vacuum to be sealed may be used. The foamed resin 33 is, for example, foamed urethane.

［蓄冷部の製造］
ここで、図２及び図３を参照して蓄冷部２０の製造について説明する。図３に示すように、まず、伝熱板１２を断熱部材３５に取り付ける。その後、伝熱板１２の外側に蓄冷材１３を密着配置する。さらに、蓄冷材１３の外側を伝熱シート１４で覆い、伝熱シート１４の外側に蒸発器配管１５を配置する。 [Manufacture of cold storage unit]
Here, manufacture of the cool storage part 20 is demonstrated with reference to FIG.2 and FIG.3. As shown in FIG. 3, first, the heat transfer plate 12 is attached to the heat insulating member 35. Thereafter, the cold storage material 13 is disposed in close contact with the outside of the heat transfer plate 12. Further, the outside of the regenerator material 13 is covered with a heat transfer sheet 14, and an evaporator pipe 15 is disposed outside the heat transfer sheet 14.

その後、蒸発器配管１５の外側から押圧平板３１を押圧して伝熱シート１４とともに蒸発器配管１５を蓄冷材１３に食い込ませる。その後、押圧平板３１の外側に複数のスペーサ３２を介在させて、真空断熱材３４を断熱部材３５に取り付ける。 Thereafter, the pressing plate 31 is pressed from the outside of the evaporator pipe 15, and the evaporator pipe 15 is bitten into the cold storage material 13 together with the heat transfer sheet 14. Thereafter, the vacuum heat insulating material 34 is attached to the heat insulating member 35 with a plurality of spacers 32 interposed outside the pressing flat plate 31.

この状態では、図２に示すように、真空断熱材３４と断熱部材３５と押圧平板３１とによって囲まれた閉空間領域Ｅが形成される。そして、閉空間領域Ｅに発泡樹脂３３を充填する。発泡樹脂材３３を加熱することによって発泡樹脂材３３は膨張する。この膨張に伴って、発砲樹脂材３３は、真空断熱材３４と断熱部材３５とが形成する凹部を金型として押圧平板３１を内側に押圧する。すなわち、押圧平板３１は、均一かつ大きな押圧力で蒸発器配管１５をさらに内側に押圧し、蒸発器配管１５を蓄冷材１３内に埋め込む。この埋め込みに伴って、蓄冷材１３及び伝熱シート１４は、蒸発器配管１５の外側にも食い込み、蒸発器配管１５は、伝熱シート１４を介した蓄冷材１３との接触面積が大きくなるとともに、蒸発器配管１５と蓄冷材１３との間の空気を追い出す。 In this state, as shown in FIG. 2, a closed space region E surrounded by the vacuum heat insulating material 34, the heat insulating member 35, and the pressing flat plate 31 is formed. Then, the closed space region E is filled with the foamed resin 33. By heating the foamed resin material 33, the foamed resin material 33 expands. Along with this expansion, the foaming resin material 33 presses the pressing flat plate 31 inward using the recess formed by the vacuum heat insulating material 34 and the heat insulating member 35 as a mold. That is, the pressing flat plate 31 presses the evaporator pipe 15 further inward with a uniform and large pressing force, and embeds the evaporator pipe 15 in the regenerator material 13. With this embedding, the regenerator material 13 and the heat transfer sheet 14 also bite outside the evaporator pipe 15, and the evaporator pipe 15 has a large contact area with the regenerator material 13 via the heat transfer sheet 14. The air between the evaporator pipe 15 and the regenerator material 13 is expelled.

その後、発砲樹脂材３３が固まることによって、蒸発器配管１５と蓄冷材１３との接触状態は維持される。 Thereafter, the foamed resin material 33 is solidified to maintain the contact state between the evaporator pipe 15 and the regenerator material 13.

本実施の形態では、蓄冷部２０の製造に際し、アルミテープや両面テープを用いた密着作業を行うことがなく、容易に熱交換効率が高い蓄冷部２０を製造することができる。また、蓄冷材１３は、伝熱シート１４を用いて蒸発器配管１５と密着するので、アルミパック製でなくてもよく、例えばポリエチレン製の袋に収容された安価なものを用いることができる。 In the present embodiment, when the cold storage unit 20 is manufactured, the cold storage unit 20 with high heat exchange efficiency can be easily manufactured without performing an adhesion work using an aluminum tape or a double-sided tape. Moreover, since the cool storage material 13 adhere | attaches the evaporator piping 15 using the heat-transfer sheet | seat 14, it does not need to be made from an aluminum pack, For example, the cheap thing accommodated in the bag made from polyethylene can be used.

［蓄冷部の変形例］
なお、上述した蓄冷材１３に替えてアルミパック製の蓄冷材１３を用いてもよい。図４に示すように、アルミパック製の蓄冷材１３は、アルミパック自体が伝熱シート１４に対応する伝熱シート４４として機能する。したがって、アルミパック製の蓄冷材１３を外側から直接、蒸発器配管１５を押圧平板３１によって押圧すればよい。 [Modification of cool storage unit]
In addition, it may replace with the cool storage material 13 mentioned above, and may use the cool storage material 13 made from an aluminum pack. As shown in FIG. 4, the regenerator material 13 made of an aluminum pack functions as a heat transfer sheet 44 corresponding to the heat transfer sheet 14. Therefore, what is necessary is just to press the evaporator piping 15 with the press flat plate 31 directly from the outer side with the cool storage material 13 made from an aluminum pack.

上述した実施の形態において、ＧＰＳセンサや通信機能を設け、外部の管理サーバに接続して保冷庫１０の流通管理、温度管理を行うようにしてもよい。 In the above-described embodiment, a GPS sensor and a communication function may be provided and connected to an external management server to perform distribution management and temperature management of the cold storage 10.

また、保冷庫１０は、蒸発器配管１５を配置せず、蓄冷材１３のみでもよい。すなわち、蓄冷材１３は、蒸発器配管１５と一体化しておらず、外部で冷却される交換可能なものであってもよい。 Further, the cool box 10 may be provided with only the cold storage material 13 without arranging the evaporator pipe 15. That is, the cool storage material 13 may not be integrated with the evaporator pipe 15 but may be exchangeable that is cooled externally.

さらに、冷凍機ユニット１１は、保冷庫本体１６と一体化せず、外部に設けてもよい。この場合、蓄冷材１３の冷却時には、外部の冷凍機ユニットに配管接続され、外部の冷凍機ユニットから冷媒を循環させる。 Furthermore, the refrigerator unit 11 may not be integrated with the cool box main body 16 and may be provided outside. In this case, when the regenerator material 13 is cooled, the refrigerant is circulated from the external refrigerator unit by pipe connection to the external refrigerator unit.

また、保冷室１６ｂ内に保冷室１６ｂを上下方向に区画する区画板を配置するための係止部やガイドを設けるようにしてもよい。 Moreover, you may make it provide the latching | locking part and guide for arrange | positioning the partition plate which divides the cold insulation chamber 16b into an up-down direction in the cold insulation chamber 16b.

なお、上述した実施の形態では、庫内を冷却する保冷庫を例に挙げたが、加熱を含めて庫内を一定温度状態に保つ蓄熱庫であってもよい。 In addition, in embodiment mentioned above, although the cold storage which cools the inside of a store | warehouse | chamber was mentioned as an example, the heat storage store | warehouse | chamber which keeps the inside of a store | warehouse in a constant temperature state including heating may be sufficient.
