Mechanism of efficient heat transfer performance of internally ribbed tubes:
During evaporation, the heat transfer area on the inner surface is increased. Due to the capillary effect, the wetted area increases; and the ribs inside the threaded pipe are spiral, thus increasing the turbulence intensity of the fluid inside the pipe.
Efficiency:
The use of internally threaded tubes can improve the efficiency of heat exchangers. Tubes with threaded tube grooves on the inner wall have higher heat transfer coefficients than normal smooth-walled tubes. The internal threaded tube was developed abroad from 1978. Currently in Japan, it has rapidly replaced the traditional smooth tube. At present, the use of internal threaded pipe in domestic air conditioners is more than 40%, and in commercial air conditioners has exceeded 50%.
Cost:
The use of internally threaded tubes can reduce the amount of aluminum tubes, aluminum heat sinks, and frame construction materials needed for the refrigeration system; reduce the refrigerant charge; reduce the power of the compressor and fan; and also increase the energy-efficiency ratio, which reduces the amount of electricity consumed; and improve the heat transfer performance of the transverse ribbed coil.
