Water Cooled Evaporator Industrial Shell and Tube Heat Exchanger

Product Introduction

The water-cooled evaporator industrial shell-and-tube heat exchanger is a type of shell-and-tube heat exchanger that uses water as a cooling medium in industrial refrigeration or air conditioning systems, allowing the refrigerant to evaporate and absorb heat within the unit.

Core Structure

Shell: Made of corrosion-resistant, high-strength materials (carbon steel, stainless steel 304/316/316L), suitable for high-pressure and corrosive environments. The shell is highly sealed to prevent media leakage, extending the equipment's lifespan.
Tube Bundle: Composed of multiple heat exchange tubes, with hot and cold media flowing inside and outside the tubes, respectively. The compact layout maximizes the heat exchange area, improving heat exchange efficiency.
Tube Sheet: Uses a dual process of expansion and welding to connect the shell and tube bundle. It has strong pressure resistance and is suitable for high-pressure conditions.
End Caps and Connectors: Inlet and outlet connectors can be configured based on different media transport requirements. The end cap is detachable for easy inspection and cleaning.
Baffle Plate: Optimizes the flow path, preventing hot and cold media from short-circuiting, enhancing turbulence, further improving heat exchange efficiency, and supporting the tube bundle to prevent vibration.

Core Advantages

Liquid-Liquid Heat Exchange: The heat transfer coefficient can reach 1000–2000 W/m²·K, significantly improving heat efficiency.
Detachable Design: The tube bundle can be fully removed for easy cleaning and maintenance.
Low Filling Requirement: The dry evaporator only requires 40% of the tube volume to be filled with refrigerant.
Easy Control: The refrigerant level is monitored in real-time by intelligent sensors and automatically adjusted.
Anti-Freeze Capability: The pipeline will not rupture when the refrigerant freezes.

FAQ
Q: Can the evaporator's heat exchange tubes be enhanced with high-performance tubes? How effective are they?
A: Yes, we commonly use enhanced heat exchange tubes such as those with internal threads or external fins. These enhanced tubes can improve the heat transfer coefficient by 30% to 100%, significantly reducing the equipment's size.

Q: When customizing the water-cooled evaporator, what key data is required in addition to the cooling capacity?
A: In addition to the cooling capacity, the following data is required: refrigerant type, secondary coolant type, inlet and outlet temperatures of the secondary coolant, allowable pressure drop, and the condenser temperature on the refrigerant side.

Q: Does the production and inspection of custom evaporators need to comply with special refrigeration industry standards?
A: Yes, in addition to ASME or PED pressure vessel standards, we also follow performance testing and safety standards from the refrigeration industry, such as AHRI and ASHRAE.

Q: What is the lead time for replacing consumable parts (such as gaskets, O-rings) in an emergency?
A: Standard consumable parts are usually in stock and can be shipped within 1-3 days. Specially customized seals typically have a lead time of about 1-2 weeks.

Q: Does the after-sales service include training for refrigeration system operators?
A: Yes, we provide training on the operation, troubleshooting, and daily maintenance of the evaporator and refrigeration system.
