Patent number: 10136474Abstract: A heat generating element for an electrical heating device of a motor vehicle, including at least one PTC element and two contact plates which are in contact with opposite sides of the PTC element and are provided on their outer side facing away from the PTC element with an insulating layer. Shielding is provided, comprising a first shell-like shielding plate and a second shell-like shielding plate which are each provided on the outer side of the insulating layer and are connected thereto in a thermally conductive manner. The longitudinal wall sections, directed towards one another, of the first and second shielding plate form an overlapping region. In order to reduce EMC problems, two shielding plates are sealed by way of an adhesive which is received in one of the two shielding plates and into which the end of a rim of the other shielding plate dips.Type: GrantFiled: July 10, 2013Date of Patent: November 20, 2018Assignee: Eberspacher catem GmbH & Co. KGInventors: Franz Bohlender, Holger Reiss, Michael Niederer, Christian Morgen

Publication number: 20110233181Abstract: The present invention relates to an electrical heating device for motor vehicles, in particular with electrical propulsion. Through a readjustment based on a comparison of set and actual values, the power is adapted to a specified power demand under continuously changing operating conditions. For this purpose, the total current passing through the heating device is measured, for example with a Hall sensor, and the momentary power consumption (actual value) determined by multiplication with the specified on-board electrical voltage.Type: ApplicationFiled: March 3, 2011Publication date: September 29, 2011Applicant: Eberspacher catem GmbH & Co. KGInventors: Holger Reiss, Benjamin Pannier

Publication number: 20110233189Abstract: The present disclosure relates to an electrical heating device for motor vehicles, in particular with electrical propulsion. The heating device uses a PWM based control concept which can be used for heating elements with any non-linear characteristics. In this respect, activation times in a cycle frame are assigned to power stages to be controlled and are stored in a table in a non-volatile memory.Type: ApplicationFiled: March 3, 2011Publication date: September 29, 2011Applicant: Eberspacher catem GmbH & Co.
