A coolant temperature control system, engine assembly and vehicle

Abstract

The invention discloses a cooling liquid temperature control system, an engine assembly and a vehicle. The cooling liquid temperature control system comprises a heat radiator (2) and a heater (8), wherein when the temperature of an engine cooling liquid is higher than the first threshold temperature, the engine cooling liquid flows through the heat radiator (2); when the temperature of the engine cooling liquid is lower than the second threshold temperature, the engine cooling liquid flows through the heater (8); the first threshold temperature is higher than the second threshold temperature; and a magnetic induction heater serves as the heater (8). The cooling liquid temperature control system disclosed by the invention has the advantages that the magnetic induction cooling liquid heater is utilized for heating the cooling liquid in the low-temperature working condition, so that the temperature of the cooling liquid can be well controlled, and an efficient and safe heating effect can be achieved; accordingly, the defects in a conventional cooling system can be comprehensively improved, the running reliability of an engine can be improved, and the service life of the engine can be prolonged; and meanwhile, the vehicle maintenance cost caused by such problems can be reduced.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a coolant temperature control system, an engine assembly and a vehicle. Background technique [0002] At present, trucks use diesel engines as the power source, and the fuel and lubricating oil inside the engine need to work at a suitable temperature. The main function of the cooling system is to keep the engine running in a suitable temperature range under all operating conditions, so that the engine can output power normally. It is an important system to ensure the normal operation, reliability, fuel consumption and service life of the engine. However, the cooling system in the prior art only has a heat dissipation function, and the ambient temperature is lower in cold and high altitude areas. Fuel oil and lubricating oil are affected by the ambient temperature, the combustion work and lubrication effect in the engine are greatly reduced, the efficiency is low, and the op...

AI Technical Summary

Problems solved by technology

However, the cooling system of the prior art only has the function of heat dissipation, and the ambient temperature is relatively low in cold and high-altitude areas

The fuel and lubricating oil are affected by the ambient temperature, the combustion work and lubrication effect in the engine are greatly reduced, the efficiency is low and the engine operation, life and reliability are affected

However, if the electric heating wire is used for heating, the direct contact between the electric heating wire and the liquid has poor reliability, and there is a great potential safety hazard. The resulting problems of engine reliability and life have also caused a burden on vehicle maintenance.
