In an air conditioner for an automobile, restriction on arrangement of electric apparatus is removed, small-sized and light-weighted formation is achieved by promoting cooling capacity of the electric apparatus by a cooling fluid by an inexpensive constitution and firm defrosting is enabled by closing an air flow path of an exterior heat exchanger. For that purpose, there are provided a refrigeration cycle having an electrically driven compressor and an exterior heat exchanger and a radiator used in an electric automobile having a driving motor for driving the automobile and a motor driving power source for driving the driving motor and connected to cool a heat generating electric apparatus such as the driving motor or the motor driving power source via the cooling fluid, the radiator is arranged in the air flow path of exterior fan and an opening and closing apparatus for opening and closing the air flow path of the exterior heat exchanger is provided.
