図１に示すように、本発明の一実施形態の中空成形品１は、第１樹脂シート３と第２樹脂シート４が部分的に溶着されてなる。樹脂シート３，４の境界に形成されるパーティングラインＰＬは、本実施形態では、中空成形品１の厚さ方向の略中央に設けられる。樹脂シート３，４の間には液体が流通可能な流路５ａ，５ｂ，５ｃが設けられている。 As shown in FIG. 1, a hollow molded product 1 according to an embodiment of the present invention is formed by partially welding a first resin sheet 3 and a second resin sheet 4. In this embodiment, the parting line PL formed at the boundary between the resin sheets 3 and 4 is provided at the approximate center in the thickness direction of the hollow molded product 1. Between the resin sheets 3 and 4, flow paths 5a, 5b, and 5c through which a liquid can flow are provided.
中空成形品１には、中空成形品１を折曲げ可能にするヒンジ部１３が２箇所設けられている。２つのヒンジ部１３は、近接して略平行に設けられている。中空成形品１は、２つのヒンジ部１３を挟む第１及び第２セクション１ａ，１ｂと、２つのヒンジ部１３によって挟まれる第３セクション１ｃに区分される。流路５ａ，５ｂは、第１セクション１ａに設けられ、流路５ｃは、第２セクション１ｂに設けられる。ヒンジ部１３は、ヒンジ部１３以外の部位よりも薄厚になっており、図５に示す金型１１，１２を用いて樹脂シート３，４を成形する際に、金型１１，１２の対向する突起間の距離をヒンジ部１３以外の部位よりも短く（好ましくは、成形前の樹脂シート３，４の合計厚さよりも短く）することによって形成することができる。ヒンジ部１３で中空成形品１を折り畳むことによって中空成形品１をコンパクトにすることができる。また、ヒーターなどの熱交換対象物を挟んで中空成形品１を折り畳むことによって、熱交換効率を向上させることができる。 The hollow molded product 1 is provided with two hinge portions 13 that allow the hollow molded product 1 to be bent. The two hinge portions 13 are provided close to each other in parallel. The hollow molded article 1 is divided into first and second sections 1 a and 1 b that sandwich the two hinge portions 13 and a third section 1 c that is sandwiched by the two hinge portions 13. The flow paths 5a and 5b are provided in the first section 1a, and the flow path 5c is provided in the second section 1b. The hinge portion 13 is thinner than the portion other than the hinge portion 13 and faces the molds 11 and 12 when the resin sheets 3 and 4 are molded using the molds 11 and 12 shown in FIG. It can be formed by making the distance between the protrusions shorter than the portion other than the hinge portion 13 (preferably shorter than the total thickness of the resin sheets 3 and 4 before molding). The hollow molded product 1 can be made compact by folding the hollow molded product 1 at the hinge portion 13. Moreover, the heat exchange efficiency can be improved by folding the hollow molded article 1 with a heat exchange object such as a heater interposed therebetween.
流路５ａは、中空成形品１の側面から突出する突出筒７ａ，７ｂに連通されている。突出筒７ａ，７ｂの先端には開口部が設けられている。このため、流路５ａ内への液体を供給するための供給チューブ（図示せず）と流路５ａから液体を排出するための排出チューブ（図示せず）を、突出筒７ａ，７ｂに連結させることによって、流路５ａ内に液体を流通させることができる。供給チューブ及び排出チューブは、突出筒７ａ，７ｂを供給チューブ及び排出チューブの開口内に挿入することによって、突出筒７ａ，７ｂに連結させることができる。供給チューブ及び排出チューブを精度良く突出筒７ａ，７ｂに連結して液漏れを防ぐには、突出筒７ａ，７ｂの外径の寸法精度を高くする必要があるところ、突出筒７ａ，７ｂは、図５に示す金型１１，１２を用いて樹脂シート３，４を成形して形成されるので、特別な操作を行うことなく、突出筒７ａ，７ｂの外径の寸法精度を高くすることができる。突出筒７ａ，７ｂの形状は、特に限定されず、供給チューブ及び排出チューブに連結可能な形状であればよい。一例では、図４（ｃ）に示すように、突出筒７ａは、円筒部７ａ１の略先端の外面に突起７ａ２が設けられた構成であり、この突起７ａ２によってチューブが突出筒７ａから抜けることが抑制される。また、図４（ｄ）に示すように、突出筒７ｂは、円筒部７ｂ１の略先端の外面に段状突起７ｂ２が設けられた構成である。段状突起７ｂ２の段の高さは、突出筒７ｂの先端から離れるにつれて高くなっている。このような構成によれば、突出筒７ｂの外径が突出筒７ｂの先端から離れるにつれて大きくなるので、突出筒７ｂを挿入するチューブの内径が変化しても、突出筒７ｂを確実にチューブに取り付けることができる。 The flow path 5a communicates with the protruding cylinders 7a and 7b protruding from the side surface of the hollow molded article 1. Openings are provided at the ends of the protruding cylinders 7a and 7b. For this reason, a supply tube (not shown) for supplying the liquid into the flow path 5a and a discharge tube (not shown) for discharging the liquid from the flow path 5a are connected to the protruding cylinders 7a and 7b. Thus, the liquid can be circulated in the flow path 5a. The supply tube and the discharge tube can be connected to the protrusion cylinders 7a and 7b by inserting the protrusion cylinders 7a and 7b into the openings of the supply tube and the discharge tube. In order to connect the supply tube and the discharge tube with high accuracy to the protruding cylinders 7a and 7b to prevent liquid leakage, it is necessary to increase the dimensional accuracy of the outer diameter of the protruding cylinders 7a and 7b. Since the resin sheets 3 and 4 are formed by using the molds 11 and 12 shown in FIG. 5, the dimensional accuracy of the outer diameters of the projecting cylinders 7a and 7b can be increased without performing a special operation. it can. The shape of the protruding cylinders 7a and 7b is not particularly limited as long as it can be connected to the supply tube and the discharge tube. In one example, as shown in FIG. 4C, the protruding cylinder 7a has a configuration in which a projection 7a2 is provided on the outer surface of the substantially tip end of the cylindrical portion 7a1, and the projection 7a2 allows the tube to come out of the protruding cylinder 7a. It is suppressed. Further, as shown in FIG. 4D, the protruding cylinder 7b has a configuration in which a stepped protrusion 7b2 is provided on the outer surface of the substantially distal end of the cylindrical portion 7b1. The step height of the stepped protrusion 7b2 increases as the distance from the tip of the protruding cylinder 7b increases. According to such a configuration, the outer diameter of the protruding cylinder 7b increases as the distance from the tip of the protruding cylinder 7b increases. Can be attached.
流路５ａは、第１セクション１ａ内で蛇行しており、流路５ａの少なくとも一部には、流路５ａ内を流れる液体の撹拌を促進する撹拌促進部６が設けられる。撹拌促進部６は、大径部６ａと、大径部６ａよりも径が小さい小径部６ｂとが長手方向に沿って交互に設けられて構成されている。このような構成によって撹拌促進部６を流れる液体の流速が変動して撹拌が促進される。また、流路５ａの側縁に沿って薄厚溶着部５ｄが設けられる。薄厚溶着部５ｄは、図５に示す金型１１，１２を用いて樹脂シート３，４を成形する際に、金型１１，１２の対向する突起間の距離を、成形前の樹脂シート３，４の合計厚さよりも短くすることによって形成することができる。このような構成によって、樹脂シート３，４が確実に溶着され、流路５ａからの液漏れを防ぐことができる。 The flow path 5a meanders in the first section 1a, and at least a part of the flow path 5a is provided with an agitation promoting unit 6 that promotes stirring of the liquid flowing in the flow path 5a. The stirring promoting portion 6 is configured by alternately providing large diameter portions 6a and small diameter portions 6b having a diameter smaller than the large diameter portion 6a along the longitudinal direction. With such a configuration, the flow rate of the liquid flowing through the stirring promoting unit 6 varies and stirring is promoted. A thin welded portion 5d is provided along the side edge of the flow path 5a. When forming the resin sheets 3 and 4 using the molds 11 and 12 shown in FIG. 5, the thin welded portion 5 d is configured to set the distance between the opposing protrusions of the molds 11 and 12 to the resin sheet 3 before molding. It can be formed by making it shorter than the total thickness of 4. With such a configuration, the resin sheets 3 and 4 are reliably welded, and liquid leakage from the flow path 5a can be prevented.
流路５ｂは、中空成形品１の側面から突出する一対の突出筒７ｅに連通されている。突出筒７ｅの先端には開口部が設けられている。突出筒７ｅは、突出筒７ａ，７ｂと同様に、供給チューブ及び排出チューブに連結させることができる。流路５ｂには、機能部品収容部９が設けられている。機能部品収容部９にはフィルタやスタティックミキサなどの機能部品を収容することができる。フィルタは、流路５ｂを流れる液体中の異物を除去することができ、スタティックミキサは、流路５ｂを流れる液体を撹拌することができる。機能部品は、図５（ｃ）に示すように金型１１，１２を閉じる前に、樹脂シート３，４の間の、機能部品収容部９に相当する部分に機能部品を配置することによって、中空成形品１内に内蔵させることができる。機能部品収容部９は嵩高いので、ヒンジ部１３で中空成形品１を折り畳んだ時に、機能部品収容部９が第２セクション１ｂに干渉しないように、第２セクション１ｂの、機能部品収容部９に対向する部位には開口部１１が設けられている。また、流路５ａと同様に、流路５ｂの側縁に沿って薄厚溶着部５ｄが設けられている。 The flow path 5b communicates with a pair of protruding cylinders 7e protruding from the side surface of the hollow molded product 1. An opening is provided at the tip of the protruding cylinder 7e. The protruding cylinder 7e can be connected to the supply tube and the discharge tube in the same manner as the protruding cylinders 7a and 7b. A functional component accommodating portion 9 is provided in the flow path 5b. The functional component storage unit 9 can store functional components such as filters and static mixers. The filter can remove foreign substances in the liquid flowing through the flow path 5b, and the static mixer can agitate the liquid flowing through the flow path 5b. As shown in FIG. 5 (c), the functional component is disposed in a portion corresponding to the functional component accommodating portion 9 between the resin sheets 3 and 4 before the molds 11 and 12 are closed, It can be incorporated in the hollow molded article 1. Since the functional component accommodating portion 9 is bulky, the functional component accommodating portion 9 of the second section 1b is prevented so that the functional component accommodating portion 9 does not interfere with the second section 1b when the hollow molded article 1 is folded by the hinge portion 13. An opening 11 is provided at a portion facing the. Similarly to the flow path 5a, a thin welded portion 5d is provided along the side edge of the flow path 5b.
流路５ｃは、中空成形品１の側面から突出する突出筒７ｃ，７ｄに連通されている。突出筒７ｃ，７ｄの先端には開口部が設けられている。突出筒７ｃ，７ｄは、突出筒７ａ，７ｂと同様に、供給チューブ及び排出チューブに連結させることができる。突出筒７ｃ，７ｄは、図４（ｅ）〜（ｆ）に示すように、略円筒状の挿入部７ｃ１，７ｄ１と、挿入部７ｃ１，７ｄ１が挿入されるチューブの先端に当接する当接部７ｃ２，７ｄ２を備える。このような構成によれば、当接部７ｃ２，７ｄ２がチューブの先端に当接するまで挿入部７ｃ１，７ｄ１をチューブ内に挿入することによって、突出筒７ｃ，７ｄの、チューブ内への挿入量を正確に規定することができる。流路５ｃは、第２セクション１ｂ内で蛇行している。また、流路５ａと同様に、流路５ｃの側縁に沿って薄厚溶着部５ｄが設けられている。 The flow path 5c communicates with the projecting cylinders 7c and 7d that project from the side surface of the hollow molded article 1. Openings are provided at the ends of the protruding cylinders 7c and 7d. The protruding cylinders 7c and 7d can be connected to the supply tube and the discharge tube in the same manner as the protruding cylinders 7a and 7b. As shown in FIGS. 4E to 4F, the protruding cylinders 7c and 7d are substantially cylindrical insertion portions 7c1 and 7d1 and contact portions that contact the distal ends of tubes into which the insertion portions 7c1 and 7d1 are inserted. 7c2 and 7d2. According to such a configuration, the insertion portions 7c1 and 7d1 are inserted into the tube until the contact portions 7c2 and 7d2 contact the tip of the tube, thereby reducing the insertion amount of the protruding cylinders 7c and 7d into the tube. Can be accurately defined. The flow path 5c meanders in the second section 1b. Similarly to the channel 5a, a thin welded portion 5d is provided along the side edge of the channel 5c.
