1results about How to "Improve flow field structure" patented technology

This application relates to a subcooler for distillate from a distillation column, belonging to the field of subcooler technology. To address the problem of unreasonable flow channel structure in subcoolers, it includes a vertical cylindrical body. A first sealing plate and a second sealing plate are disposed within the vertical cylindrical body, with a plurality of subcooling tubes running through the space between the first and second sealing plates. One end of the vertical cylindrical body has a cooling medium inlet and a distillate inlet, while the other end has a cooling medium outlet and a distillate outlet. A circumferentially extending spiral guide groove is formed on the inner wall of the vertical cylindrical body, and a plurality of arc-shaped guide plates are staggered within the vertical cylindrical body. Each arc-shaped guide plate has stepped protrusions on its surface. This application has the effect of optimizing the flow field structure, significantly reducing flow resistance, and improving heat exchange efficiency.
