Problems solved by technology
Some materials, such as silicon, may contain beneficial properties regarding fluid tightness and coefficient of friction, but are only used in restricted cases due to legal regulations
The use of many other sealing materials, such as grease, leads to an unfavorably high complexity of the assembly process and thus increases manufacturing costs

Embodiment Construction
[0027] figure 1 An isometric view of an electric heater 1 according to an embodiment of the invention is shown. The electric heater 1 according to the invention can be used, for example, in a heating or air-conditioning system of a motor vehicle. In this case, the electric heater 1 is used to heat the air passing through the heat transfer surface of the electric heater 1 in order to supply warm air into the passenger compartment of the motor vehicle.
[0028] For this purpose, heating or air conditioning systems usually include a figure 1 housing shown in. The housing includes an air duct formed by the walls of the housing. A blower is used to generate an air flow in which air is sucked in from the environment of the motor vehicle or / and outside the passenger compartment and blown through the casing so that the air in the air flow is subsequently heated by the electric heater 1 . In the direction of air flow, after the electric heater 1 , the air is guided through the duct...
