ELECTRIC HEATING APPARATUS, HEAT SUPPLY, VENTILATION AND/OR AIR CONDITIONING APPARATUS AND MOTOR VEHICLE

摘要

An electric heating apparatus (1), a heat supply, ventilation and/or air conditioning apparatus comprising the electric heating apparatus (1), and a motor vehicle comprising the heat supply, ventilation and/or air conditioning apparatus. The electric heating apparatus (1) comprises a housing (2) and a control module contained in the housing (2); the housing (2) is block-shaped and the dimension thereof along a first direction (z) is larger than that in a second direction (y), the first direction (z) being perpendicular to the second direction (y); the control module comprises a busbar (3), and the busbar (3) comprises a positive busbar terminal (3A) and a negative busbar terminal (3B) that form an interface for a wire harness (4). The wire harness (4) is used for an input current and comprises a positive wire harness terminal (4A) and a negative wire harness terminal (4B), and the wire harness (4) extends along the first direction to the interface. At the interface, the positive wire harness terminal (4A) and the negative wire harness terminal (4B) are electrically connected to the corresponding positive busbar terminal (3A) and negative busbar terminal (3B). The housing (2) of the electric heating apparatus (1) has no additional thickness along the second direction (y), providing the electric heating apparatus (1) with good adaptability to a narrow installation environment along the second direction (y).
