Heat exchanger for motor vehicle air conditioning has tubes containing electrical resistances spaced by separators

摘要

The heat exchanger for motor vehicle air conditioning has heating bars (10) seated in tubes (18) of conductive material and each having an electrode (14) extending along the tube. An electrical insulation (12) is positioned between the electrode and the tube and electrical resistances (16) are seated in the tubes. The resistances are mutually spaced longitudinally in the tubes using separators (15).
