Title: Alfred Joekel: Innovator in Heat Transfer Technology
Introduction
Alfred Joekel is a notable inventor based in Essen-Werden, Germany. He has made significant contributions to the field of heat transfer technology, holding a total of four patents. His innovative approaches have advanced the methods used in producing finned heat transfer tubing.
Latest Patents
One of Joekel's latest patents is a method and device for winding spiral fins onto oval tubing. This device is designed to produce finned heat transfer tubing of oval cross-section by winding continuous metal strips around the tubing in the form of spiral fins. The contact edge of the metal strip is shaped prior to winding to present a hook-shaped ledge with an acute enclosed angle. Additionally, the neutral axis for on-edge bending is shifted to the vicinity of the contact edge by applying tensile stress to the strip and additional transverse compression stress to its upper half, utilizing a stretch roller and a cooperating winding guide. Another significant patent is a device for the cold working of heat exchanger tubing for attachment. This device cold rolls narrow flat lands on the cylindrical surface of heat exchanger tubing just before winding metal strips for the production of finned tubing. It features pressure rollers on pressure levers carried by a journalled supporting spindle that rotates with the tubing, along with a control sleeve inside the hollow spindle that interrupts the rolling action as desired while the winding operation continues.
