How to Optimize the Design of Finned Tube Phase Change Heat Storage
Finned tube structure Finned tubes are widely used in power, chemical and other industries. Many spiral heat transfer surfaces or threaded tubes can be regarded as finned tubes. It has a significant effect on expanding the heat transfer area and promoting turbulence, and it has a great effect on both single-phase-convection heat transfer and phase-change convective heat transfer. The structure of the finned tube heat exchanger is basically the same as the general shell and tube heat exchanger. Just use finned tubes instead of light tubes as the heat transfer surface. Finned tube heat exchangers are also often used to heat or cool the gas outside the tube, and steam or water is passed through the tube, such as air coolers, boiler economizers, radiators, etc. Finned tube material The finned tube has a wide range of materials, including stainless steel, carbon steel, titanium and copper alloys, etc. The corrosion resistance of the industry has greatly increased.
