Small Heat Exchanger Internal Thread Aluminum Alloy Tubing ECR D7mm
Product Description:
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.
Applications:
condensator
evaporimeter
air conditioner external unit
Small heat exchanger
frigistor
packaged air conditioner
Dry wet machine,
etc.
