Coaxial tube heat exchanger
Coaxial heat exchanger, also called "shell heat exchanger", consists of a spiral grooved inner tube and an outer tube, and the cold and hot fluids flow in the annular gaps of the inner tube and the outer tube respectively. The concentric shell is designed with different thread patterns to increase the heat exchange contact area and transmit different fluids, thereby achieving efficient heat transfer. Coaxial shell heat exchanger is a high-efficiency, compact, widely used, and easy to maintain heat exchanger.

Technical Features
Self-descaling
The cross-sectional size of the water side flow channel is large, and the fluid flows and flushes in a spiral, which is not easy to clog and scale.
High efficiency heat exchange
Spiral groove structure greatly improves the heat transfer coefficient
Fewer welding points and higher pressure bearing
Less welding in processing and manufacturing, reducing the risk of leakage in long-term use.
Long life
The spiral casing has a higher ability to resist pressure vibration and impact than the plate structure, adapts to complex working conditions, and has a longer service life.
Wide range of materials
Stainless steel, titanium, nickel white copper, etc.
How it works
The working principle of the coaxial heat exchanger is mainly based on its unique structural design and heat transfer principle: the coaxial heat exchanger consists of a concentric inner tube and outer tube, forming an annular space. The cold and hot fluids flow in the annular spaces of the inner tube and outer tube respectively, thereby realizing heat transfer. The refrigerant and the coolant exchange heat, the refrigerant flows in the interlayer between the inner and outer tubes, and the coolant flows in the inner tube.
