摘要：
PURPOSE: A plastic multilayer pipe is provided to sufficiently endure the operating pressure of a coolant and to prevent the outflow of the coolant or the inflow of external air. CONSTITUTION: An internal layer(1) is contacted to a coolant and is formed by a low-reactive resin to chemically stabilize against the coolant. An intermediate layer(5) is formed by a resin to isolate gas for preventing the outflow of the coolant or the inflow of external air. An external layer(9) is formed by one among an LLDPE(Linear Low Density Polyethylene), an LDPE(Low Density Polyethylene), a polystyrene, a polypropylene, a polyurethane or a nylon to protect the intermediate layer and to stabilize against external oxygen or moisture. Adhesive layers(3,7) are formed by an adhesive resin to stick the internal layer to the intermediate layer and to stick the intermediate layer to the external layer. Thereby, the efficiency of a cooler is increased.
摘要（中）：
目的：提供塑料多层管，以充分承受冷却液的工作压力，并防止冷却液流出或外部空气流入。 构成：内部层（1）与冷却剂接触并由低反应性树脂形成，以化学稳定地抵抗冷却剂。 中间层（5）由树脂形成以隔离气体，以防止冷却剂流出或外部空气流入。 外部层（9）由LLDPE（线性低密度聚乙烯），LDPE（低密度聚乙烯），聚苯乙烯，聚丙烯，聚氨酯或尼龙之一形成，以保护中间层并稳定抵抗外部氧气 或水分。 粘合层（3,7）由粘合剂树脂形成，以将内层粘合到中间层并将中间层粘附到外层。 由此，冷却器的效率提高。
