Title: Elmar Hoff: Innovator in Thermoplastic Tube Sheet Technology
Introduction
Elmar Hoff is a notable inventor based in Bochum, Germany. He has made significant contributions to the field of thermoplastic materials, particularly in the production of tube sheets used in heat and mass transfer applications. With a total of 3 patents to his name, Hoff's work exemplifies innovation and practical application in engineering.
Latest Patents
Hoff's latest patents include a process for producing a tube sheet and the tube sheet itself for apparatuses designed for transferring heat and/or mass. The first patent outlines a method for fabricating an injection-molded tube sheet made from thermoplastic material. This process involves distributing a melt in the injection mold over the entire cross-sectional area before pressing it into the mold region where the tube sheet is formed. Each hole in the tube sheet is created using a needle disposed within the mold. After cooling, the portion of the thermoplastic melt that overlays the needles is removed, resulting in the final tube sheet.
The second patent describes the characteristics of the injection-molded tube sheet, which features at least 25 through-holes for tube ends. The hydraulic diameter of these holes is at most 3 mm, and the minimum web width between neighboring holes is no more than 0.4 mm. The thickness of the tube sheet ranges from 3 to 10 mm, making it particularly suitable for compact arrangements of tube ends in heat and mass transfer apparatuses.
