Cooling system for vehicle liq. cooled engine - has cooling fan driven by hydrodynamic motor with flow through thermostatically controlled

摘要

The cooling system is for liq. cooled engines, partic. vehicle IC engines, is conventionally arranged with a radiator, circulating pump and fan-assisted cooling. The fan is driven by a hydrodynamic motor (10) fitted in a loop (8) parallel to the hot coolant line to the radiator (4), with a thermostatically operated valve (9) at one end or the other and to regulate flow distribution between the two. There is also the usual thermostatically controlled radiator bypass line (12, 13). The line for the fan motor can alternatively be run between the coolant return line from the radiator and this.
