Seamless Steel Pipe Shell Water Cooled Heat Exchanger Industrial Refrigeration
The heat exchange tube uses copper pipe, nickel-copper alloy tubes, aluminum brass tube and stainless
steel tube as the material and the shell uses No.20 seamless steel tube and stainless steel tube.
Shell and tube heat exchanger materials are generally carbon steel, stainless steel and copper-based, in
which carbon steel tube plate as a cooler, the tube and tube pipe welds often appear corrosion leakage,
spill into The cooling water system pollutes the environment and causes material waste.
The heat transfer coefficient of the shell-and-tube chiller evaporator is larger in the liquid than in the gas,
in the flow state than in the stationary state.
Shell and tube chiller evaporator due to better heat transfer, compact structure, small footprint, easy
installation, so the application is very extensive. The structure of the shell and tube chiller evaporator is
the same as that of the horizontal shell and tube condenser. In order to control the proper flow rate, the
refrigerant enters from the lower part of the end cap, flows out from the upper part and flows back and
forth within the duct and the end cap, and becomes a multi-way flow. And the refrigerant flows outside the
tube, and the refrigerant liquid after the throttling enters from the bottom or the side of the evaporator,
and the gas after the fire is discharged from the upper part.
