Cooling system for electric motor vehicle with electric drive motor - includes pump and cooling line for non-freezing coolant soln. which is force-circulated through pipeline for cooling heat produced by electric drive motor and cooled by radiator and fan.

摘要

The coolant soln. is recirculated by a pump (4). A control unit (1) is provided for controlling the electric drive motor (2). A cooling fan mounted at the radiator (3) is driven by a separate electric motor (6). The radiator is interposed in the pipeline (5) between the pump and the electric drive motor (2). The heat produced is recirculated through a battery, and a passage is provided for the heating of a heater (8). This passage is provided with a valve, which can be changed over to supply the coolant to the battery or to the heater. ADVANTAGES - Cooling system is resistant to freezing independent of time of year. Recirculates heat produced in motor and control unit which is available for auxiliary purposes.
