Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile engineering thermal management equipment, in particular to an air inflow control structure for automobile power assembly heat dissipation. BACKGROUND

[0002] In the field of new energy vehicles, efficient heat dissipation of power components (batteries, motors, and electronic control systems) is crucial for vehicle performance and safety. Existing air inflow control structures mainly achieve heat dissipation through active and passive technologies. Passive structures include air intake grilles and guide plates. Fixed grille designs rely on vehicle speed to introduce cooling air, and guide plates guide air to the battery pack or motor accurately. The chassis apron reduces turbulence interference by optimizing airflow paths. Active control technology focuses on active air intake grilles (AGS) and electronic cooling fans. AGS can automatically adjust the opening degree based on battery temperature, motor load, and other parameters, reducing wind resistance when closed and enhancing heat dissipation when opened. Electronic fans use PWM speed control in conjunction with temperature sensors to achieve on-demand cooling. Some models use zoned guide systems to divide the intake into separate channels to cool the battery and motor, improving heat dissipation specificity. These structures are based on fluid mechanics principles, optimized for airflow paths through CFD simulation, and combined with lightweight materials (such as carbon fiber guide plates) and low wind resistance designs to reduce energy consumption while ensuring heat dissipation efficiency, meeting the stringent requirements of new energy vehicles for thermal management systems.

[0003] The existing patent CN112644414B relates to a driving mechanism for achieving different timing movements of grille blades. It includes a frame and at least two grilles on the frame, connected to an electric motor through a crank and connecting rod mechanism. Each grille includes a driven blade with a drive shaft. The crank and connecting rod mechanism includes a drive rod with at least two sliding grooves. The drive shaft extends through the sliding grooves. The sliding grooves include a movement segment and a holding segment. The movement segment is at an angle to the direction of the drive rod, while the holding segment is parallel to the direction of the drive rod. When the drive shaft of the driven blade in one of the grilles is in the movement segment of its corresponding sliding groove, the drive shaft of the driven blade in the other grille is in the holding segment of its corresponding sliding groove. This invention can control the sequence of opening and closing of different grilles and achieve asynchronous driving of multiple grilles by a single motor.

[0004] However, in order to ensure that the battery is at the best working temperature during the charging process of the existing new energy vehicle, the battery pack often needs to be actively cooled. Although the air intake grilles of the power assembly and the battery are separated and controlled in most vehicle models, the battery air intake grille still relies on an electric actuator (such as a motor drive) to adjust the opening degree by receiving an electrical signal from the battery management system (BMS). This method has the problems of additional energy consumption and high system complexity. On the one hand, the electric control needs to continuously consume vehicle power, increasing the energy loss during the charging process. On the other hand, the complex electric control system is easily affected by high temperature and vibration, resulting in high failure rate and high maintenance cost. SUMMARY
