Latest Patents

One of Haecheon Choi's latest patents is an innovative air conditioner designed to suppress the generation of leakage vortices between a fan and a shroud. This air conditioner features an axial fan that blows air, a shroud that partially surrounds the fan to guide the airflow, and a fence ring that protrudes from the inner surface of the shroud. The fence ring is strategically placed between the downstream end of the axial fan and the downstream end of the shroud, improving the overall efficiency of the air conditioning system.

Another notable patent is a wake disturbing apparatus and method for reducing drag. This invention aims to significantly decrease drag caused by a sharp drop in pressure behind objects with blunt trailing edges, such as vehicles traveling at high speeds. The apparatus consists of multiple disrupters arranged at regular intervals along the trailing edge of the object. These disrupters protrude to a predetermined height, reducing the vortical strength of the wake and recovering pressure at the base surface. This innovative solution allows for considerable drag reduction without altering the vehicle's structure or requiring additional energy, thereby maximizing energy consumption efficiency.
