The invention belongs to the technical field of engines, and in particular relates to a low-temperature cooling system, a vehicle and a control method for the low-temperature cooling system. The low-temperature cooling system in the present invention includes a low-temperature circulating radiator, an electronically controlled water pump, an electronically controlled proportional valve, an intercooler group, and an expansion tank. The liquid outlet of the water control pump is connected with the liquid inlet of the electric control proportional valve, the liquid outlet of the electric control proportional valve is connected with the liquid inlet of the intercooler group, the liquid inlet of the expansion tank is connected with the intercooler group The liquid outlet is connected, and the liquid outlet of the expansion tank is connected with the liquid inlet of the low-temperature circulating radiator. By using the low-temperature cooling system in this technical solution, the electronically controlled proportional valve is used to intelligently distribute the intercooler group, which reduces the waste of cooling intensity. At the same time, the electronically controlled water pump is used to control the flow of the coolant, saving the overall Energy consumption of the cryogenic cooling system.
Description
technical field [0001] The invention belongs to the technical field of engines, and in particular relates to a low-temperature cooling system, a vehicle and a control method for the low-temperature cooling system. Background technique [0002] The traditional inter-stage intercooler adopts air-to-air cooling, which has low cooling efficiency, and the cooling intensity is affected by the speed of the vehicle and cannot be controlled. In addition, the cooling intensity required by the two-stage intercoolers is different. If only a single cooling pipeline is used for cooling, it is easy to There is a problem with overcooling or overheating. However, if the LP-EGR (low pressure exhaust gas recirculation) system is cooled by engine cooling water, the temperature after cooling cannot meet the demand for low fuel consumption, and the waterway layout is complicated. - The control ability of EGR is weak, and the cooling water flow of each cooling component cannot be intelligently di...
