Abstract

The invention belongs to the technical field of engine systems, and particularly relates to an engine thermal management system and a vehicle. The engine thermal management system comprises a water tank, a cooling unit, an engine body set and a gas path unit, the inlet end of the cooling unit communicates with the outlet end of the water tank, the inlet end of the engine body set communicates withthe outlet end of the cooling unit, the outlet end of the engine body set communicates with the inlet end of the water tank, an output pipeline of the gas path unit is provided with a gas pressure nozzle capable of outputting different gas pressures, and the gas pressure nozzle is used for spraying gas into a communicating pipeline between the cooling unit and the machine body set. By using the engine thermal management system in the technical scheme, thermal management operation can be efficiently completed under the warm-up working condition and the normal working condition, an air film canbe formed on the surface of the engine body set when high air pressure is input through the air pressure nozzle under the warm-up working condition, heat dissipation losses can be effectively reduced, and low air pressure is input through the air pressure nozzle under the normal operation working condition, turbulence disturbance can be formed in cooling liquid, and the heat dissipation efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of engine systems, and in particular relates to an engine thermal management system and a vehicle. Background technique [0002] With the upgrading of fuel consumption regulations and the improvement of engine strengthening, the role of engine thermal management has gradually become prominent. Advanced thermal management systems can not only improve the thermal efficiency of the engine, but also reduce engine emissions. In the prior art, structures such as an electronic water pump, a dual-temperature circulation system, and electronically controlled valves are used to realize thermal management operations of the engine, but the structure is complex and the management efficiency is low. Contents of the invention [0003] The purpose of the present invention is to at least solve the problem of the low thermal management efficiency of the prior art. This purpose is achieved through the following technical so...
