The annular sealing member 4 is configured to seal the outer peripheral edge of the flow channel body 3 and to have the inflow port 8 and the outflow port 9 so that the lid members 1 and 11 are brought into contact with both surfaces of the cylindrical body 2. A synthetic resin material is used so that the outer peripheral surface of the surface of the lid members 1 and 11 and the outer peripheral wall of the cylindrical body 2 including the inflow port 8 and the outflow port 9, that is, the outer peripheral edge of the flow channel body 3, are annularly covered with the molding die By integrally molding, the molded body has an inflow port 8 and an outflow port 9, and is formed as a ring-shaped molded body made of a synthetic resin material and having a U-shaped cross section.

There may be only a junction part with sealing member 4 without. Preferably, a thin film layer made of the chemical treatment agent may also be formed on the outer peripheral wall of the cylindrical body 2.

The annular sealing member 7 is an annular and U-shaped molded body formed by integrally molding with a molding die so as to annularly cover the outer peripheral edge of the flow path body 31 with a synthetic resin material. The outer peripheral edge of the flow path body 31 is hermetically sealed by the sealing member 7, the cylindrical body 6 has an inlet 8 and an outlet 9, and the lid member 5 closes the space 61 of the cylindrical body 6 to generate a heating element. A heat exchanger B having an H mounting portion is obtained. In this case, the sealing member 7 is a ring-shaped and U-shaped molded body formed integrally with a synthetic resin material so as to annularly cover the outer peripheral edge of the flow path body 31, and as the synthetic resin material, Is the same as in the first embodiment, and is a polyphenylene sulfide resin, polyethylene resin, polypropylene resin, polystyrene resin, polycarbonate resin, polyvinyl chloride resin, polyethylene terephthalate resin, polybutylene terephthalate resin, polyethylene naphthalate. Thermosetting resins such as thermoplastic resins such as phenolic resins, polybutylene naphthalate resins, fluorine resins, and polyether ether ketone resins, and phenolic resins can be exemplified.
また、流路本体31の外周縁を密閉させる封止部材7の形成においては、封止部材7を筒体6と密着接合させる必要があるので、実施形態1と同様に金属と樹脂との密着接合を成形型にて一体に成形により行っているが、好ましくは、板状の蓋材5の表面の外周面および筒体6が金属材でできている場合には筒体6の環状鍔部60の外周面に、予め、実施形態1のように、メルカプト基、チオカルボニル基、シアノ基、イソシアナート基、アミノ基、アンモニウム基、ピリジニウム基、アジニル基、カルボキシル基、ベンゾトリアゾール基、トリアジンチオール基等の何れかまたはこれらを組み合わせた化学的処理剤からなる薄膜層が形成されることにより、蓋材5の素材または筒体6の素材である金属材と封止部材7の素材である合成樹脂材の高分子との接合をしやすくした状態で、封止部材7となる合成樹脂材で蓋材5および筒体6を成形型にて一体に成形すれば、これらの密着接合がさらに強固となる。Further, in the formation of the sealing member 7 that seals the outer peripheral edge of the flow path body 31, the sealing member 7 needs to be tightly bonded to the cylindrical body 6, so that the metal and the resin are closely bonded as in the first embodiment. Joining is performed by molding integrally with a molding die. Preferably, when the outer peripheral surface of the surface of the plate-like lid member 5 and the cylindrical body 6 are made of a metal material, the annular flange portion of the cylindrical body 6 60, in advance, as in Embodiment 1, mercapto group, thiocarbonyl group, cyano group, isocyanate group, amino group, ammonium group, pyridinium group, azinyl group, carboxyl group, benzotriazole group, triazine thiol By forming a thin film layer made of a chemical treatment agent that is a group or a combination of these, a synthetic material that is a material of the lid member 5 or a material of the cylindrical body 6 and a material of the sealing member 7 resin If the lid member 5 and the cylindrical body 6 are integrally formed with a molding die using a synthetic resin material to be the sealing member 7 in a state in which the polymer can be easily joined to each other, these tight junctions are further strengthened. .
なお、筒体6が合成樹脂材でできている場合には、蓋材5の素材は金属材であるが、筒体6は合成樹脂材で成形されており、成形された筒体6を成形型にて封止部材7となる合成樹脂材で成形されて環状で断面コ字状の成形体となった封止部材7を得るに際して、特に筒体6の環状鍔部60と密着接合させる必要があるので、筒体6および封止部材7の合成樹脂材組み合わせを選定して成形することが好ましい。その好ましい成形方法のひとつとして、筒体6にはポリブチレンテレフタレート樹脂などのレーザ吸収性樹脂材を用い、封止部材7にはポリトリメチレンテレフタレート樹脂などのレーザ透過性樹脂材を用いて成形型にて一体に成形した後、筒体6(特に環状鍔部60)と封止部材7との接合部位にレーザ照射により溶かして接合加工を行って筒体6の環状鍔部60と封止部材7とを密着接合させる。また、他の成形方法として、筒体6には低密度ポリエチレン樹脂などの融点が低い素材とし、封止部材7には高密度ポリエチレン樹脂などの融点が高い素材とするように樹脂組成が殆ど同じで融点の異なる熱可塑性樹脂材を組み合わせて成形することにより、筒体6の環状鍔部60と封止部材7とを密着接合させる。In addition, when the cylinder 6 is made of a synthetic resin material, the material of the lid member 5 is a metal material, but the cylinder 6 is formed of a synthetic resin material, and the molded cylinder 6 is formed. When obtaining the sealing member 7 which is molded with a synthetic resin material which becomes the sealing member 7 in the mold and becomes a ring-shaped molded body having a U-shaped cross section, it is particularly necessary to closely bond with the annular flange 60 of the cylindrical body 6 Therefore, it is preferable to select and mold the synthetic resin material combination of the cylindrical body 6 and the sealing member 7. As one of the preferable molding methods, a mold using a laser-absorbing resin material such as polybutylene terephthalate resin for the cylindrical body 6 and a laser-transmitting resin material such as polytrimethylene terephthalate resin for the sealing member 7 is used. After being molded integrally with the tube 6, the joining portion between the tubular body 6 (particularly the annular flange 60) and the sealing member 7 is melted by laser irradiation to perform a joining process, and the annular flange 60 and the sealing member of the tubular body 6 are performed. 7 is tightly bonded. Further, as another molding method, the cylindrical body 6 is made of a material having a low melting point such as a low density polyethylene resin, and the sealing member 7 is made of a material having a high melting point such as a high density polyethylene resin so that the resin composition is almost the same. Then, the annular flange 60 of the cylindrical body 6 and the sealing member 7 are tightly joined by molding by combining thermoplastic resin materials having different melting points.

この場合、流路本体31’の外周縁を合成樹脂材で一体に成形して密閉する環状の封止部材7の形成においては、筒体6’の環状鍔部60’は金属材でできているので、蓋材5と環状鍔部60’との接合には、合成樹脂材と金属材との一体成形の作業で行えるので、ろう付けもしくは溶接の作業を必要としない。この場合、蓋材5と環状鍔部60’とが密着接合をさせる必要があるので、好ましくは、蓋材5と筒体6’の環状鍔部60’の外周面に、予め、メルカプト基、チオカルボニル基、シアノ基、イソシアナート基、アミノ基、アンモニウム基、ピリジニウム基、アジニル基、カルボキシル基、ベンゾトリアゾール基、トリアジンチオール基等の何れかまたはこれらを組み合わせた化学的処理剤からなる薄膜層が形成されることにより、蓋材5の素材または筒体6’の環状鍔部60’の素材である金属材と封止部材7の素材である合成樹脂材の高分子との接合をしやすくした状態で、封止部材7となる合成樹脂材で蓋材5および筒体6’を成形型にて一体に成形すれば、蓋材5および筒体6’と封止部材7との密着接合がさらに強固となる。In this case, in the formation of the annular sealing member 7 that integrally molds and seals the outer peripheral edge of the flow path body 31 ′ with a synthetic resin material, the annular flange portion 60 ′ of the cylindrical body 6 ′ is made of a metal material. Therefore, since the lid member 5 and the annular flange 60 'can be joined by an integral molding operation of the synthetic resin material and the metal material, brazing or welding is not required. In this case, since it is necessary for the lid 5 and the annular flange 60 'to be in close contact with each other, it is preferable that the outer periphery of the lid 5 and the annular flange 60' of the cylindrical body 6 'be preliminarily provided with a mercapto group, A thin film layer comprising a chemical treatment agent such as thiocarbonyl group, cyano group, isocyanate group, amino group, ammonium group, pyridinium group, azinyl group, carboxyl group, benzotriazole group, triazine thiol group, or a combination thereof. Is formed so that the metal material that is the material of the lid member 5 or the material of the annular flange 60 'of the cylindrical body 6' and the polymer of the synthetic resin material that is the material of the sealing member 7 can be easily joined. In this state, if the lid 5 and the cylinder 6 ′ are integrally formed with a molding die using a synthetic resin material to be the sealing member 7, the lid 5 and the cylinder 6 ′ and the sealing member 7 are closely bonded. Becomes even stronger.
