20100045421 | Electric Circuit With Thermal-Mechanical Fuse - 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. | 02-25-2010 |
20110051388 | PRINTED CIRCUIT BOARD WITH A FUSE AND METHOD FOR THE MANUFACTURE OF A FUSE - Some invention embodiments relate to a method for forming a fuse which electrically connects two metal surfaces ( | 03-03-2011 |
20110069943 | Apparatus for Heating Fluids - The invention relates to an apparatus for heating fluids, comprising a housing in which a duct runs, through which the fluid to be heated can flow and which leads from a housing opening for fluid to enter to a housing opening for fluid to exit. According to the invention, the duct extends in several convolutions along a housing wall carrying at least one heater housing, in which at least one electric heating element is arranged. | 03-24-2011 |
20130163971 | ELECTRIC HEATING DEVICE - The invention relates to an electric heating device for a motor vehicle, said electric heating device comprising a ceramic heating resistor and a metal cooling body, which has two mutually opposed primary sides, wherein one of the two primary sides forms an inflow side, against which a fluid stream to be heated flows. In accordance with this disclosure, the heating resistor is arranged in a groove, which is located in one of the two primary sides of the cooling body. | 06-27-2013 |
20140061174 | HEATING ROD AND METHOD FOR PRODUCTION THEREOF - 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. | 03-06-2014 |
20140217089 | 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. | 08-07-2014 |
20140355965 | VEHICLE HEATER - 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. | 12-04-2014 |
20150117848 | METHOD FOR MANUFACTURING AN ELECTRICAL HEATING DEVICE AND HEATING DEVICE - 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. | 04-30-2015 |
