What is a coaxial heat exchanger?

Essentially, a coaxial heat exchanger is a tube heat exchanger, commonly used as a condenser or evaporator in heat pumps, ship air conditioners, swimming pools, chillers, and other types of HVAC systems. It is designed as a "tube-in-tube" structure. The structure of the coaxial heat exchanger can be round, rectangular, spiral, double spiral, etc.

The working mode of the coaxial heat exchanger is that water mainly flows in the inner tube, and refrigerant flows between the outer tube and the inner tube (this is called a refrigeration circuit). And because the cooling temperature and water temperature are different, the heat will be transferred from one of the high temperature to the other. This is the counter-flow heat transfer principle, which allows extensive use of refrigerant vapor superheating and liquid refrigerant superheating.

Structure of coaxial heat exchanger

The coaxial heat exchanger is designed as a "tube in tube" structure. Usually, the outer tube is made of steel/copper. According to the requirements of working conditions, the inner tube can be titanium, copper, copper-nickel alloy. Because there are many spiral grooves on the surface of the inner tube, this will enlarge the connection surface and get more heat transfer.

How does the coaxial heat exchanger perform heat exchange?

The water flow in the inner tube is mainly the refrigerant flow (refrigeration circuit) between the outer tube and the inner tube. The cooling temperature is different from the water temperature, so the heat will be transferred from the high temperature one to the other. Mainly countercurrent.

The above is a coaxial heat exchanger model launched by YOJO as a coaxial heat exchanger provider. Water flows into the inner tube from the bottom and flows out from the top. The refrigerant gas will flow into the refrigeration loop from the larger diameter copper tube, and the refrigerant liquid will flow out from the smaller diameter copper tube.
