The triangular spiral filler, Fenske spiral is made of wound wire, triangular spiral filler, Fenske spiral is similar to its shape and springs, also known as the triangle spring filler. It is the difference between the spring winding circle is not round but each triangle, circle and circle the triangle between the staggered certain angle, so triangular spiral filler, Fenske spiral packing direction from the end to see such a polygonal packing more efficient, but compared to the ring packing, the resistance slightly larger, mainly for the laboratory.
