Electric heater with housing
First Claim
1. An electric heater, particularly as an auxiliary heating means for automotive vehicles, comprising a housing which is made open on the elongate housing faces, and a layered structure consisting of at least one PTC heating element, a radiator element, contact sheets for power supply and a resilient element, the layered structure being kept clamped in the housing by the resilient element, wherein an opening is provided laterally in the housing for inserting the resilient element.

Abstract
The present invention relates to a novel constructional principle for electric heaters, wherein the functions of frame and resilient means are separated from one another. As a frame for an electric heater, a housing is used that consists of two half-shells. Positioning aids for the PTC heating elements are arranged in the housing. The longitudinal sides of the housing are essentially made open to allow for air throughput through the heating register. A resilient device is additionally inserted into the housing, the resilient device compressing the layered structure of radiator elements, PTC heating elements and contact sheets. After the heater has been assembled, the resilient device can be inserted through a lateral opening into the heater.

32. A method for producing an electric heater, particularly as an auxiliary heating means for automotive vehicles, comprising a housing consisting of two half-shells and made open on the elongate faces of the housing, and a layered structure consisting of at least one PTC heating element, a radiator element, contact sheets for power supply and a resilient element, the layered structure being kept clamped by the resilient element in the housing, with the following mounting steps:
-
inserting the contact sheets, the radiator element, and the PTC heating element into a first half-shell of the housing, attaching the second half-shell of the housing to the first half-shell, and inserting the resilient element through an opening of the assembled housing to effect a clamping of the layered structure.
