How Hubei Chemical Machinery Strengthens the Heat Transfer Performance of Fin Tube Heat Exchangers

The thermal storage heat exchanger relies on a thermal storage medium composed of solid fillers to transfer heat, with hot and cold fluids alternately flowing through the channels made up of the thermal storage medium. When the hot fluid flows through, it stores heat in the thermal storage medium, causing its temperature to gradually rise. When the cold fluid flows through, the thermal storage medium releases heat, causing its temperature to gradually decrease, and this process repeats.

Enhanced heat transfer technology for shell and tube heat exchangers in Hubei chemical machinery

Change the shape of the heat transfer surface and set various shapes of inserts on the heat transfer surface or within the heat transfer flow path. There are many ways to change the shape of the heat transfer surface, among which those used to enhance heat transfer in the tube side include: spiral groove tubes, corrugated tubes, threaded tubes, scaled tubes, swirling tubes, and spiral flat tubes, etc. Additionally, flow disturbance elements can be used, such as filling the tube with twisted iron, spiral rings, or metal sheets, which can also enhance turbulence and disrupt the laminar boundary layer.

The general types of methods for enhancing heat transfer in Hubei chemical machinery shell courses.

One is to change the form of the shell-side baffle or tube support to reduce or eliminate the stagnant dead zones in the shell-side flow and heat transfer, so that the heat transfer area can be fully utilized. Examples include baffle heat exchangers, hollow ring heat exchangers, spiral baffle heat exchangers, etc.
