用于机动车工作液罐的，具有PTC‑塑料体的加热装置
摘要：
本发明涉及一种用于特别是为了储存水状尿素溶液的机动车工作液罐的加热装置(10)，其中加热设备(10)具有：两个电导体(12，14)；一个设置在两个电导体(12，14)之间的和使所述两个电导体(12，14)电接触的，由PTC‑塑料构成的物体(16)；和一个至少局部地保护电导体和PTC‑塑料体(16)免受外部环境(22)的影响的护套(18，20)，该加热装置的特征在于：至少一个电导体(12，14)至少局部由金属箔(12，14)，特别是铝箔构成并且护套(18，20)是‑优选与金属箔连接的‑绝缘面，特别是塑料膜(18，20)。
摘要（英）：

A heating device (10) for a motor vehicle operating fluid tank, in particular for storing aqueous urea solution, wherein the heating device (10) has two electrical conductors (12, 14), an element (16) made from PTC plastic, which is electrically arranged between the two electrical conductors (12, 14) and is in electrical contact with the two electrical conductors (12, 14), and a shell (18, 20), which protects the electrical conductors and the PTC plastic element (16) from the outside environment (22) at least in some sections, which is characterized in that at least one electrical conductor (12, 14) is made at least in some sections from a metal foil (12, 14), in particular aluminum foil, and that the shell (18, 20) is an insulating surface, in particular a plastic film (18, 20) that is preferably bonded to the metal foil.
