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.
