Dry Expansion Type Tube Heat Exchanger Seamless Steel Pipe Shell Long Life
Dry evaporators can be made of bare tubes, but also with
longitudinal fins of the finned tube made of
straight tube or u-shaped tube structure, but their overall
structure is basically the same.
The advantage of the dry evaporator is that the amount of the
refrigerant is small; when the temperature
is controlled by the temperature relay, it is sensitive to the load
change, the liquid supply is accurate; the
refrigerant flow rate is quick and the oil return is good; the
refrigerant is flowing outside the pipe, Flow
resistance loss is small; water for the refrigerant, the water in
the tube outside the constant mixing, rarely
icing phenomenon.
This evaporator when the aluminum core with the fin tube, the heat
transfer coefficient of up to 1000 ~
1200kcal / m2h ℃; with a small diameter dense tube, the heat
transfer coefficient of up to 900 ~ 1000kcal
/ m2h ℃.
The spiral baffle plate evaporator is the latest product designed and made by Qiaoxin and has obtained
the national technical patents, which can save 20% in copper consumption and 30% in ferrous metals,
reach the total energy saving rate 30% after test and satisfy the national economic policy of industrial
upgrading, saving energy and reducing consumption and environmental protection.
