ELECTRIC HEATING DEVICE AND VEHICLE AIR CONDITIONER

摘要

[Problem to be Solved] An object is to provide an electric heating device that can heat fluid efficiently at a time of intermediate output, and a vehicle air conditioner including the electric heating device. [Solution] To include a plurality of flow paths in which fluid flows and a plurality of heating modules arranged adjacent to the flow path and including heating elements that generate heat by energization. At the time of intermediate output, the heating element in the heating module provided adjacent to a flow path among the plurality of flow paths having a relatively large flow rate of fluid is energized.
