Electrical heating device for motor car, has waving ribs arranged transverse to passage direction of medium, cooling body sealingly inserted into connector housing, and sealing element bridges gap between body and contours of housing

摘要

The device has a layer structure (46) arranged in a frame (44) and comprising layers of waving ribs and heat generating elements. One of the heat generating elements include positive temperature co-efficient (PTC) elements, which are arranged between parallel contact plates. Waving rib elements are arranged one behind the other in a passage direction of medium e.g. water. The ribs are arranged transverse to the passage direction of the medium. A cooling body (32) is sealingly inserted into a connector housing, and a sealing element bridges a gap between the body and contours of the housing. An independent claim is also included for a frame.
