Abstract
In order to get understand the process of the heat exchanging and flow field and design heat exchangers with more flexibility, computational fluid dynamics was used to design the heat exchanger of 4kW fast axial flow CO2 laser. The flow resistance of the heat exchanger is 154.5Pa and its heat transfer is 8888.5W. The heat exchanger can ensure the long-term stability of fast axial flow CO2 laser. The research proves that computational fluid dynamics theory can make the design process of heat exchanger more efficient and accurate.
