Definitions

  • the invention relates to a heater, in particular for a motor vehicle, and a method for producing the same.
  • Electric heaters especially air heaters (especially those used in mobile applications) are often based on ceramic heating elements with a comparatively strong temperature-dependent electrical resistance, through which a self-regulation of the heat release is possible.
  • These resistors are usually PTC ceramic elements (PTC for Positive Temperature Coefficient). These are usually connected to heat exchanger surfaces made of aluminum sheet and are also contacted electrically.
  • a PTC element comprises a PTC resistor, ie a temperature-dependent resistor with a positive temperature coefficient, which conducts the electric current better at low temperatures than at high temperatures.
  • Disadvantages of conventional heaters, in particular air heaters with ceramic PTC elements include u.a. an elaborate production by a comparatively complicated heat exchanger production and the installation of the ceramic elements, a usually necessary sorting of the ceramic elements due to manufacturing tolerances, a comparatively unfavorable power density in a heating element heat exchanger composite by a local heat generation, a relatively strong restriction a maximum heating power through a thickness of the PTC material (due to a limited heat dissipation from the ceramic) and a comparatively high risk of short circuit, in particular due to a low geometric

Beschreibung description
Die Erfindung betrifft ein Heizgerät, insbesondere für ein Kraftfahrzeug, sowie ein Verfahren zur Herstellung desselben. The invention relates to a heater, in particular for a motor vehicle, and a method for producing the same.
Elektrische Heizgeräte, insbesondere Luftheizgeräte (insbesondere solche, die in mobilen Anwendungen eingesetzt werden) basieren oftmals auf keramischen Heiz-Elementen mit einem vergleichsweise stark temperaturabhängigen elektrischen Widerstand, durch den eine Selbstregelung der Wärmeabgabe ermöglicht wird . Bei diesen Widerständen handelt es sich üblicherweise um keramische PTC-Elemente (PTC für Positive Temperature Coefficient). Diese sind in der Regel mit Wärmeübertrager-Flächen aus Aluminiumblech verbunden und werden darüber auch elektrisch kontaktiert. Ein PTC-Element umfasst einen PTC- Widerstand, also einen temperaturabhängigen Widerstand mit einen positiven Temperaturkoeffizienten, der bei tiefen Temperaturen den elektrischen Strom besser leitet als bei hohen Temperaturen. Electric heaters, especially air heaters (especially those used in mobile applications) are often based on ceramic heating elements with a comparatively strong temperature-dependent electrical resistance, through which a self-regulation of the heat release is possible. These resistors are usually PTC ceramic elements (PTC for Positive Temperature Coefficient). These are usually connected to heat exchanger surfaces made of aluminum sheet and are also contacted electrically. A PTC element comprises a PTC resistor, ie a temperature-dependent resistor with a positive temperature coefficient, which conducts the electric current better at low temperatures than at high temperatures.
