技术领域
本发明涉及在机动车辆中用作温度控制管，特别是冷却剂管的管的使用，其中温度控制介质通过该管。这种温度控制管优选地应用于机动车辆的温度控制线路中，其中温度控制介质尤其是液体温度控制介质通过该温度控制管。在特别优选的方式中，温度控制管构造成冷却剂管并且作为机动车辆的冷却线路的一部分，冷却剂通过该冷却剂管。根据本发明的温度控制管的一种特别优选的应用是，用于电动车辆或者具有电动机和内燃机的混合动力机动车辆的温度控制系统中。根据本发明的温度控制管，特别是冷却剂管，特别用于电池系统的温度控制或冷却。
背景技术
从实际操作中，已知很多不同设计的温度控制管或冷却剂管。众所周知，温度控制管尤其还用于控制机动车辆部件的温度。然而迄今为止，管在其耐温性和/或其绝热性上经常遗留一些期待解决的方面。另一方面，如果具有足够的耐温性和满意的隔热性的管可以被制造，这通常伴随着大量的努力或材料消耗并因此具有高成本。同样，实际操作中已知的大量温度控制管不具有足够的机械阻力，即使在机动车辆中特别需要该机械阻力。
DE 60030161 T2公开了在机动车辆中用于输送冷却剂的管。其涉及多层管，包括：硫化弹性体的外层，聚酰胺的隔层或中间层，以及硫化弹性体的内层。外层和中间层以及中间层和内层通过粘合层彼此连接。这种机动车辆管本身未得到证实，特别是隔热性上遗留一些期待解决的方面。
发明内容
相应地，本发明的技术目的是提供管，该管可以有效地用作温度控制管并且满足所有要求，特别是有关其隔热性、耐温性以及机械强度方面，并且可以用少的花费和低成本持续生产。
为达到该目的，本发明公开了在机动车辆中用作温度控制管，特别是冷却剂管的管的使用，其中温度控制介质通过该管，该管从外至内包括如下层状结构：
至少一种，优选地一种聚烯烃(polyolefin)的外层；
第一粘合层；
至少一种，优选地一种聚酰胺(polyamide)的隔层；
第二粘合层；
至少一种，优选地一种聚烯烃的内层；
其中，管的总壁厚为0.5至3.5mm，优选地为0.5至3mm；
并且其中，外层由聚乙烯(polyethylene)或者基本上由聚乙烯组成，或者外层由聚丙烯(polypropylene)或者基本上由聚丙烯组成。
根据本发明的温度控制管可以用于具有内燃机的传统机动车辆的温度控制系统中。根据本发明的特别设计，根据本发明的温度控制管用于电动车辆的温度控制系统中或者具有电动机和内燃机的混合动力机动车辆的温度控制系统中。
根据本发明的一个优选设计，该管用作温度控制系统中的温度控制管，用于控制机动车辆的电池温度或者用于冷却机动车辆的电池。根据本发明的另一优选设计，管用作机动车辆的空调系统的温度控制管。
本发明的推荐设计的特征在于，该管用作温度控制管，用于电动机动车辆或者混合动力机动车辆的机动车辆电池的温度控制或者冷却。
在本发明的范围内，流体介质特别是液体介质用作温度控制介质或者用作冷却介质。出于实用的目的，温度控制介质或者冷却介质包括液体混合物，并且优选地包括醇-水(alcohol-water)混合物。强烈推荐的设计的特征在于，乙二醇-水(glycol-water)混合物用作温度控制介质或者冷却介质。
在本发明的范围内，根据本发明的温度控制管的外层由聚乙烯组成或者基本上由聚乙烯组成。优选地，外层因此由HDPE组成或者基本上由HDPE组成。根据本发明的另一设计，外层由聚丙烯组成或者基本上由聚丙烯组成，并且根据一种变型设计，所述外层由HDPP组成或者基本上由HDPP组成。
根据本发明，第一粘合层设置在外层和隔层之间。根据本发明的一个优选设计，第一粘合层是聚烯烃基或者聚酰胺基粘合剂层。本发明的一种推荐设计的特征在于，第一粘合层具有用羧酸诱导剂(carboxylic acid derivative)-特别是马来酸诱导剂(maleicacid derivative)-改性的聚烯烃，或由该改性的聚烯烃组成或基本上由该改性的聚烯烃组成。
根据本发明，聚酰胺的隔层设置在温度控制管的中间或者在温度控制管的第一粘合层和第二粘合层之间。本发明强烈推荐的设计的特征在于，隔层由聚酰胺6组成或者基本上由聚酰胺6组成。该设计尤其证明了其自身在本发明的范围内。在本发明的范围内，隔层由来自于或基本上由来自于“聚酰胺6，聚酰胺612，聚酰胺10，聚酰胺11，聚酰胺12，半芳族聚酰胺(semi-aromatic polyamide)，共聚酰胺(co-polyamide)”组中的至少一种物质组成。但是聚酰胺6优选地用于隔层。在本发明的范围内，隔层构造成比第一粘合层和/或第二粘合层厚。出于实用的目的，隔层比第一粘合层和/或第二粘合层厚至少1.2倍，优选地厚至少1.5倍，更优选地厚至少1.8倍。
根据本发明，第二粘合层设置在根据本发明的管或温度控制管的隔层和内层之间。根据本发明的一种优选设计，第二粘合层是聚烯烃基或聚酰胺基粘合层。根据本发明的设计变型，第二粘合层是用羧酸诱导剂改性的聚烯烃，特别是用马来酸诱导剂改性的聚烯烃。
