Embodiment Construction

[0028] In the drawings, the same reference numerals designate the same or similar parts, which are at least partially not explained more than once to avoid repetition.

[0029] figure 1 A schematic partial perspective view of a first embodiment of vehicle heater 10 is shown and at the same time process steps for producing said vehicle heater 10 are shown.

[0030] exist figure 1 The vehicle heater 10 shown in and all vehicle heaters described hereinafter may be air heaters and so-called water heaters, such as, but not limited to, for electric or hybrid vehicles. Air heaters differ from so-called water heaters in that in an air heater the air flow to be heated is led directly through the heat exchanger of the air heating device, whereas in a so-called water heater first a liquid, usually water (hence the name water heater) and antifreeze (such as ethylene glycol) mixture is directed through the water heater's heat exchanger to transfer heat to the desired location with the ai...

Abstract

A vehicle heater (10) has a main body (12) which supports a non-intrinsically safe heat conductor layer (14), and a sensor device (16, 18, 20) assigned to the heat conductor layer (14) and provided to detect if a temperature threshold is exceeded. The sensor device (16, 18, 20) comprises a sensor layer (16) which is arranged on the side of the heat conductor layer (14) facing away from the main body (12) and which is monitored with respect to current flows that may occur substantially in the direction of the surface normal (42) of the sensor layer. In a method for producing a vehicle heater (10), a main body (12) of the vehicle heater (10) is equipped with a non-intrinsically safe heat conductor layer (14) and a sensor device (16, 18, 20) for detecting if the temperature threshold is exceeded. A sensor layer (16) is assigned to the heat conductor layer (14) on the side of the layer facing away from the main body (12) to form the sensor device (16, 18, 20) and is provided to monitor current flows which may occur substantially in the direction of the surface normal (42) of the sensor layer (16).

Description

technical field [0001] The invention relates to a vehicle heater comprising a body carrying a non-intrinsically safe heat-conducting layer and a sensor device assigned to the heat-conducting layer, the sensor device being arranged to detect an exceeding of a temperature threshold. [0002] The invention also relates to a method of manufacturing a vehicle heater, in particular a vehicle heater as described herein. According to said method, it is intended that the body of the vehicle heater is equipped with a non-intrinsically safe heat-conducting layer and sensor means for detecting exceeding of a temperature threshold. [0003] The body can in both cases be, for example, a heat exchanger, in particular of the metal / air and / or metal / liquid type. Background technique [0004] In contrast to intrinsically safe heat-conducting layers, such as PTC heat-conducting layers, which are able to independently prevent excessive temperature rises by limiting the current, all types of hea...
