Product information
For situations where there is no phase change medium on both sides, in gas-gas, liquid-liquid and gas-liquid heat exchange processes, Lanke High-tech has developed a spiral flat tube heat exchanger, which can simultaneously strengthen the media inside and outside the tube.
1. Strengthen heat transfer mechanism
Due to the unique structure of the spiral flat tube, the tube side and shell side are in spiral flow at the same time, which promotes the degree of turbulence. Longitudinal rotation and secondary swirl flow are formed on the tube side; the cross section of the shell-side fluid channel changes periodically along the longitudinal direction of the tube bundle, increasing the degree of turbulence, destroying the fluid boundary layer, and enhancing shell-side heat transfer.
2. Core components
The structural feature of the spiral flat tube is that any cross-section of the heat exchange section of the tube is an oval or ellipse. The manufacturing of the spiral flat tube is completed by two forming processes: flattening and heat twisting. There is no baffle on the shell side, and it relies on the point contact of the spiral line on the outer edge of the spiral flat tube for self-support.
3. Performance advantages
High heat exchange efficiency is 1/3 higher than traditional heat exchangers;
Strong resistance to fouling and corrosion;
The bundling structure does not require baffles, and the inside and outside are all spiral flow;
The outer edges of the heat exchange tubes are in close contact with the spiral lines, and the self-supporting structure overcomes fluid-induced vibrations. It has strong anti-vibration ability and saves 30 to 60% of materials;
There are no baffles on the shell side, there is no flow dead zone, and the resistance is small.
