Coaxial Heat Exchanger

Coaxial heat exchanger consist of one spiral grooves inner tube and a outer tube. Cold liquid and heat liquid flow in the gap that between inner and outer tube or in inner tube separately.

Structure Feature

High efficiency
Spiral groove structure can enhance heat transfer on both sides. The axial flow and spiral rotation flow of the fluid in the tube will intensify the mixing of the fluid near the tube wall, thus enhancing the turbulence intensity and increasing the heat transfer coefficient

Self-cleaning ability
The coaxial heat exchanger has self-cleaning ability because the fluid spiral flow washes the surface. Coaxial heat exchanger has stable performance and low attenuation. The cross-section area of the waterway is large, allowing sediment and large diameter fibers to pass through without blocking. The water passage is clean because the inner tube of the spiral groove keeps the flow turbulent and cleans the surface

Effective prevention of freezing
Water is not easy to freeze because it is turbulent when it flows at a low speed in a spiral groove. The special spiral groove structure of the inner tube makes the inner tube flexible to a certain extent and does not produce the risk of frost cracking.

Less risk of leakage
Heat exchangers are very worried about leakage due to long-term vibration, pressure fluctuation, alternation of heat and cold, and so on. The risk of leakage of coaxial exchangers is seldom due to fewer welding points, simple processing and easy control of welding quality

Adapt to all kinds working conditions
In the actual operation of refrigeration system, the internal pressure is often in an alternate state due to temperature fluctuation, start-stop cycle, heat pump defrosting, expansion valve regulation and other factors. Spiral coaxial heat exchanger is more resistant to pressure shock and pressure shock than plate heat exchanger under constant vibration and pressure change, and can adapt to the complexity of actual working conditions

Kinds of coaxial heat exchanger that APT design and produce

1 Based on shape
Circle ,Rectangle,Double helix,Spiral,Trombone

2 Based on system No.
Single system,Double helix type 3 systems,Trombone interspersed 2 systems,Trombone type 6 systems,Spiral type 9 systems
