The invention relates to a vehicle heater, comprising at least one pipe, which has a plurality of chambers, ceramic heating elements, which are arranged in the chambers, and contact plates, which rest against the heating elements in the chambers via a front side and face an upper side or underside of the chamber via a rear side, wherein at least two chambers of the pipe are separated by an intermediate wall, which runs from the upper side to the underside of these two chambers. The contact plates have a slit, in which the intermediate wall is arranged.

Vehicle heater

What is described is a method for manufacturing an electrical heating device, wherein electrical heating resistors are disposed in tubes of an extruded profile, and openings are cut into a plate of the extruded profile connecting the tubes. According to this disclosure, fastening sections of the extruded profile are plastically deformed and, by means thereof, heat sinks are fastened on the extruded profile. A corresponding electrical heating device is also described.

Method for manufacturing an electrical heating device and heating device

This disclosure relates to a method for producing a heating rod for a vehicle heating apparatus, said method comprising the following steps: arranging at least one PTC element and at least one contact element in a tube, which is formed from sheet metal and is open along a longitudinal side; welding portions of the sheet metal that bear against one another by means of a weld seam running in the longitudinal direction of the tube. This disclosure also relates to such a heating rod.

Method for producing a heating rod

The invention relates to a heating rod, comprising a housing made of metal, a heating element disposed in the housing, and a contact plate, which is seated against the heating element with a front and which protrudes from the housing. It is provided according to this disclosure that the contact plate is an aluminum sheet having an anodized back and the contact plate comprises projections for positioning the heating element.

Heating rod

The invention describes a heating apparatus comprising at least one heater () in which one or more electric heating elements () are arranged, and at least one heat transmitter (), which is connected with the at least one heater (), comprises heat transmitter surfaces and is formed from an extruded profile () in which the at least one heater () is fitted, in which at least part of the walls () of the extruded profile (), which are not in contact with a heating element (), is provided with openings through which a gaseous or liquid medium can flow through the extruded profile () in transverse direction to the direction of extrusion ().

Electric heating apparatus, especially for motor vehicles

The invention relates to a heating device comprising at least one tube housing in which at least one PTC heating element is arranged, and heat exchangers which are secured on the tube housing. According to the invention, it is provided that the heat exchangers are secured on the tube housing by stamping.

Electric heating device

Some invention embodiments relate to a method for forming a fuse which electrically connects two metal surfaces () that are arranged on a printed circuit board () next to each other and spaced apart from each other. It is provided according to the invention that the two metal surfaces () are each partially covered with a protective coating (), wherein a partial region forming a contact region () remains uncovered, liquid soft solder material () which bridges the gap between the two metal surfaces () is applied onto the two uncovered partial regions (), and the protective coating () in a surrounding area of the solder material () is removed after the soft solder material () has solidified, in order to form receiving regions () which are wetted by the solder material () when the latter fuses, with the result that the solder material () flows off from a printed circuit board region () between the two metal surfaces () and the electrical contact formed by the solder material () is interrupted. Furthermore, other invention embodiments relate to a printed circuit board with such a fuse.

Method for manufacture of a fuse for a printed circuit board

An electric heating system, in particular an auxiliary heating system in automobiles, in which the heating system has several heating rods (), arranged side-by-side; the heating rods () are connected to each other by means of alike metal plates () that are slid onto the heating rods (); the heating rods () have for this purpose a series of slotted holes () that extend in the longitudinal direction () of the metal plates (); the slotted holes () have longitudinal edges, facing each other, that clamp the heating rods () between them; and at least one part of the slotted holes () in each metal plate () is longer by more than the manufacturing tolerance, than the width of the heating rods () measured in the longitudinal direction () of the metal plates ().

Electric heating system, in particular for use as an auxiliary heating system for automobiles

A tire pressure control system includes a tire valve and wheel electronics including a pressure measuring device and a transmission device in a housing, wherein the housing has two base elements on a bottom for attaching the same to a rim well of a wheel, and a contact surface seated on a valve spud of the tire valve in the mounted state. The surface has an elongated hole through which the tire valve projects in the mounted state. The invention provides that the contact surface can be linearly displaced in the direction of the elongated hole on the valve spud during installation.

Tire pressure control system

A electric circuit includes a connection to a current source, an electric load, and a thermal-mechanical fuse which, in the case of failure at an excessive heat emission, interrupts the current supply to the load, which is effectuated by a feeder in which is arranged a spring having two ends, at least one end is soldered to a solder point provided in the feed line. The one solder point is under a mechanical pretension caused by the restoring force of a spring, that separates the solder joint between the spring and the solder point in the feed line, when the solder melts at the solder point.
