Description

Technical Field

[0001] The present invention relates to the technical field of thermal management equipment for commercial vehicles, and in particular to a windshield device for a commercial vehicle intercooler, a control method, and a commercial vehicle. Background Art

[0002] To improve engine performance, supercharged engines are becoming increasingly common. In a supercharged engine, the air temperature rises significantly after passing through the supercharger. An intercooler is used to cool the supercharged air before it enters the engine for combustion.

[0003] In order to meet the cooling effect, the air-cooled intercooler in the related technology usually maximizes the cooling capacity. However, in a low temperature environment, such as the winter in the north, the intercooler has excessive cooling capacity, resulting in too low an intake temperature after the intercooler, affecting the fuel atomization effect, causing problems such as deteriorated combustion and oil dilution. When the intake temperature is lower than 0°C, there is also a risk of throttle and intake manifold freezing.

[0004] In the prior art, in order to solve the problem that commercial vehicle intercoolers are prone to icing in low temperature environments, which affects the intake efficiency and heat dissipation performance, the following protection solutions are mainly adopted: the first is to apply a hydrophobic coating on the surface. By spraying a layer of special hydrophobic coating on the surface of the intercooler, the micro-nano structure of the coating surface is used to greatly reduce the surface energy, making it difficult for water vapor to condense into ice on the surface; the second is to install a windshield at the air inlet. A baffle is set at the air inlet of the intercooler to block part of the cold air and reduce the amount of cold air directly flowing through the core surface, thereby slowing down the temperature drop rate. For example, the intercooler with patent number CN106150671A and the automobile having it include : An intercooler body, the intercooler body having an inlet, an outlet and an air-cooled heat dissipation surface located between the inlet and the outlet; a windshield, the windshield is arranged on one side of the air-cooled heat dissipation surface of the intercooler body and can move relative to the intercooler body; a driving device, the driving device is transmission-connected to the windshield, and the driving device drives the windshield to move to change the area of ​​the air-cooled heat dissipation surface blocked by the windshield; The third method is to use the waste heat of the engine coolant for heating, and a coil or a heating plate is set in the intercooler core, and the engine coolant is introduced through it, and part of the engine waste heat carried away by the coolant is used to heat the core and raise the surface temperature.

[0005] While applying a hydrophobic coating to a surface can delay frost formation, ice formation is still inevitable in harsh environments with extremely low temperatures and saturated humidity. Furthermore, long-term exposure to high-velocity cold airflow and erosion by particulate matter can cause the coating to gradually age, crack, and fall off, significantly reducing its anti-icing performance. Tests show that after 500 hours of use, the coating's hydrophobicity decreases by over 30%. Once ice forms, the coating actually aggravates ice adhesion, resulting in limited anti-icing effectiveness and the coating's aging and flaking. While adding a windshield to the air inlet can reduce the amount of cooling applied to the core surface, precisely adjusting the windshield's angle is difficult, making anti-icing effectiveness difficult to achieve under complex and variable operating conditions. Precisely adjusting the shielding area makes it difficult to guarantee effective anti-icing. While utilizing engine coolant waste heat for heating can increase surface temperature to some extent, it presents numerous challenges. Firstly, during idle and low-load conditions, the coolant temperature is low, resulting in insufficient waste heat and limited heating effectiveness. Secondly, the coolant temperature fluctuates widely, making thermal coupling difficult to control, easily leading to overcooling or overheating and poor temperature control accuracy. Furthermore, the complex coolant piping and seals, exposed to high temperatures, high pressures, and high-velocity airflow, lead to frequent leaks and blockages, resulting in low reliability and limited temperature control accuracy.

[0054] In this embodiment, by analyzing and mining a large amount of CFD simulation data and real vehicle collected data, a deep neural network is constructed with environmental parameters (temperature, humidity, atmospheric pressure), engine operating parameters (speed, intake air volume, coolant temperature), driving operating parameters (vehicle speed, gear position, braking status), etc. as input, and intercooler temperature field, frost amount, heat dissipation efficiency, engine fuel efficiency, emissions, etc. as output. Through offline training, a mapping relationship library of environment-operating condition-control parameters is formed, and a reinforcement learning algorithm is used for strategy iterative optimization. The anti-icing target temperature and the target deflection angle of the windshield 11 at this target temperature can be quickly obtained.

[0055] In this example, offline training of the thermal management coupling analysis model to form a library of mapping relationships between the environment, operating conditions, and control parameters of the windshield 11 also includes obtaining the corresponding relationships between the heating power of the heating mechanism 5 and the environment, operating conditions, and control parameters of the windshield 11.
