  • Turbulator for a heat exchanger tube, and method of manufacture
    Publication number: 20090183857
    Abstract: A turbulator for a heat exchanger tube, and a method of manufacturing the heat exchanger tube. The turbulator comprises a mesh, ideally a woven mesh, of material, ideally metallic wires. The mesh is formed into corrugations of a size substantially to fill the heat exchanger tube. The method comprises the steps of: making a mesh of material; forming the mesh into corrugations; and fitting the corrugated mesh into the heat exchanger tube so that the corrugated mesh substantially fills the heat exchanger tube for some or all of its length. The turbulator and method are particularly suited to flat heat exchanger tubes.
