Finned heat exchanger GJ-CP100

The finned heat exchanger is a device that enhances heat transfer by adding fins. It is widely used in fields such as air conditioning, refrigeration, chemical engineering, and power generation. Its core structural components are as follows: 

Main heat transfer components 

The tube is the basic heat transfer element, and the fluid (liquid or gas) flows inside the tube. It is divided into smooth tubes or internal threaded tubes. 

Fin is a thin metal sheet that is welded or expanded onto the outer surface of the base pipe, significantly increasing the heat transfer area and facilitating the heat exchange of the fluid (usually gas) outside the pipe. It is divided into flat fins, corrugated fins, slotted fins, and helical fins. 

Structural Framework 

A tube bundle is a core heat transfer unit composed of multiple finned tubes arranged in a certain pattern. 

The tube sheet is a metal plate that fixes the ends of the tube bundle and ensures the spacing between the tubes as well as separating the fluids. 

The casing/shell is used to protect the internal structure and guide the flow of fluids. 

The baffles are installed in the shell side (the space outside the tubes) to change the flow path, increase the flow velocity and enhance the turbulence. 

Fluid Distribution Component 

The header is a collecting pipe used to distribute or gather the fluid within the pipes. It is usually located at both ends of the heat exchanger. It is divided into staged headers and collecting header boxes. 

The nozzle is used to connect the external pipeline and guide the flow of fluid into and out of the heat exchanger. 

Auxiliary Components 

The support frame is used to fix the overall structure and prevent vibration or deformation. 

Seals (gaskets/seals) are used to prevent fluid leakage (especially in multi-process or high-pressure situations). 

The guide vanes are used to optimize the airflow distribution and prevent dead zones.
