Product details
Ⅰ. Brief Introduction
The secondary refrigerant passes through the heat exchange tube, the refrigerant flows in the shell side and completely immerses the heat exchange tube, and evaporates outside the heat exchange tube after absorbing heat.
Ⅱ. Product Details
1. Shell and tube Evaporator are the efficient Shell and Tube Heat Exchanger developed in the air-conditioning and refrigeration industries.
2. There are many pin-shaped small holes on the surface of the heat exchange tube, and there are spiral protrusions on the inner surface of the tube to strengthen the heat transfer on the secondary refrigerant side. This high-efficiency heat transfer tube that simultaneously enhances boiling outside the tube and heat transfer inside the tube increases its heat transfer coefficient by about 3 to 5 times compared to the smooth tube.

Ⅳ. Advantages, Features and Application
1. Adopt 1.1mm thickness special heat exchange tube, T-shaped heat exchange tube greatly increases the heat transfer area.
2. The product has obtained many national patents.
3. The secondary refrigerant passes through the heat exchange tube, the refrigerant flows in the shell side. The heat transfer between the liquid refrigerant and liquid secondary refrigerant. The gaseous refrigerant generated directly enters the compressor, which greatly improves the heat exchange efficiency.
4. Adapt to compressors such as screw, centrifugal and magnetic type. The difference between the effluent temperature and the evaporation temperature approaches and low resistance.
Ⅴ. Company Service
WIELAND and the HTRI are used to calculate the heat transfer performance of the Shell and Tube Heat Exchanger, and the heat transfer performance test is performed on the product based on the H.Stars Group's independent test platform. The product strength calculation uses SW6-2011v4.0 software in the pressure vessel industry to calculate its strength, and has passed the inspection by the Guangzhou Municipal Quality and Technical Supervision Bureau. The company has passed ISO9001 quality management system certification, ISO14001 environmental management system certification, and obtained pressure vessel design license and D-level pressure vessel manufacturing license. Over 20 years of technical accumulation has accumulated rich design experience to keep our products continuously leading.
Ⅵ. Product Maintenance
1. The flow rate of the fluid in the tube side or the shell side not only affects the heat transfer efficiency, but also affects the thermal resistance of the dirt. Choosing the right flow rate is very important. Limiting the flow rate of feed water, when a series of heat exchangers are deactivated or the number of heat exchange tube blockages is large, the flow rate in the tubes will be significantly increased. At this time, some feed water should be bypassed to enter the unit or reduce the load of the unit.
Ⅶ. FAQ
1. How much liquid flow rate is appropriate in heat exchange tube?
A: The liquid flow rate inside heat exchange tube should be 1 ~ 3m/s.
