Products Description
A coaxial heat exchanger is an essential component in a water source heat pump, providing an efficient way to transfer heat from the ground to the heat pump. It plays a crucial role in the overall functioning of the system and ensures a consistently high level of performance.
The water source heat pump is an eco-friendly and cost-effective way to heat or cool a building. It utilizes renewable energy sources, such as geothermal energy, to provide heating or cooling. The coaxial heat exchanger helps to achieve this by providing efficient heat transfer from groundwater to the heat pump. Its design ensures that the heat transfer process is both efficient and reliable, making it an ideal component for water source heat pumps.
Furthermore, the coaxial heat exchanger has a number of benefits, including a compact design that makes it easy to install in various locations. It is also highly durable, with a long lifespan and low maintenance requirements. This means that it is a cost-effective solution for both residential and commercial buildings.

The coaxial heat exchanger is designed as a "tube-in-tube" structure. The outer tube material is steel/copper, and the inner tube can be made of titanium, copper, or copper-nickel alloy according to the working conditions. Since there are many spiral grooves on the surface of the inner tube, the connection surface is expanded and more heat transfer is obtained.
Since the temperature of the refrigerator and the water are different, heat will be transferred from the higher temperature side to the other side. This is the counter-heat transfer principle, which allows extensive utilization of superheating of refrigerant vapor and subcooling of liquid refrigerant.
- Our tube's multi-channel inner groove effectively provides a water slide to prevent freezing and damage.
- We offer standard models in round, trombone, rectangular, double helix and spiral shapes. You can also send us your specifications and we can custom design to fit your dimensions.
- Our coaxial heat exchangers are ideal for heat pump water heaters, air/water source heat pumps and more. The inner tube can be lined with copper, white copper, stainless steel and titanium.
