Water Cooled Evaporator Shell and Tube Heat Exchanger

A water-cooled evaporator shell and tube heat exchanger is a shell-and-tube evaporator that uses water as the cooling medium. It cools process fluids or systems by absorbing heat through the evaporation of refrigerant inside the tubes or in the shell. It is widely used in industrial refrigeration, central air conditioning, chemical and energy systems.

High heat exchange efficiency: Utilizes a multi-pass shell-and-tube structure with high thermal conductivity heat exchange tubes, resulting in a large heat transfer area and stable flow.

Mature structure: The shell-and-tube structure conforms to TEMA/ASME design principles, offering strong pressure resistance and good adaptability to water quality fluctuations.

Easy maintenance: Heat exchange tubes can be mechanically or chemically cleaned, and single tube or tube bundle replacement is supported.

Corrosion Protection, Scale Control, and Special Operating Condition Design

Shell：Cylindrical carbon steel or stainless steel pressure vessel for refrigerant containment.

Tube Bundle：High-efficiency heat transfer tubes fixed to tube sheets; baffles guide shell-side flow to enhance heat transfer.

Flow Arrangement：Water flows through tubes, refrigerant on the shell side (flooded or dry), allowing easy cleaning and stable evaporation.

End Caps (Water Chambers)：Removable water chambers for flow distribution and mechanical cleaning; single-, two-, or multi-pass options.

Auxiliary Components：Safety valve, sight glass, drains, and temperature/pressure connections.

Installation：Level the foundation, allow maintenance clearance, and avoid external stress on nozzles during piping connection.

Water Treatment：Cooling water must be softened, filtered, and treated to prevent scaling, corrosion, and biofouling.

Maintenance：Monitor water quality regularly.Periodically remove end caps and clean tube interiors.Check for refrigerant leaks and insulation damage.

Safety：This is a pressure vessel. Design, manufacture, and operation must comply with applicable standards (e.g., ASME, PED, GB 150). Personnel must be trained.
