Latest Patents

One of her latest patents is a "Needle for pressing internally-finned pipes." This invention comprises a cylindrical portion and a portion with longitudinal profiled channels intended to form the internal fins of a pipe. The design features an intermediate portion that varies in diameter, decreasing and then increasing from the cylindrical portion to the profiled channels. This needle is specifically used for pressing pipes with internal fins whose height exceeds their thickness by more than four times.

Another notable patent is for a "Tubular heat exchanger." This heat exchanger includes ribs mounted transversely along the axis of the tube, with each rib featuring a plate that has corrugations oriented along the fluid flow. The innovative design of the ribs, which includes lateral slits, reduces the thickness of the boundary layer and enhances the effectiveness of heat exchange. Additionally, this heat exchanger is more compact and requires less metal for construction compared to traditional designs.
