The invention discloses an engine
electric control auxiliary cooling
system freeing from an engine rotational speed influence. The engine
electric control auxiliary cooling
system comprises an electronic water pump which is sequentially connected in series with an engine, a thermolator, a heat radiator and an
air heating core and is connected in parallel with a mechanical water pump; the outlet of the electronic water pump and the inlet of the mechanical water pump are respectively provided with a one-way valve; the electronic water pump is provided with an electronic water pump controller; the
signal input end of the electronic water pump controller is respectively connected with an engine cooling
liquid temperature sensor on the water outlet of the engine and an engine controller; and the
signal output end of the electronic water pump controller is connected with the electronic water pump. According to the engine electronic control auxiliary cooling
system provided by the invention, the power requirement on the mechanical water pump from the cooling system is reduced, thereby the volume and
layout requirements of the mechanical water pump are reduced; the application of the engine cooling system provided by the invention adopts an
operation mode of mainly relying on the mechanical water pump supplemented by the electronic water pump, and has the advantages of convenience for operation, high reliability, low cost, good applicability and easiness for popularization.
