A stamped fin (also known as a plate fin) refers to a type of heat transfer component used in heat exchangers. These fins are thin metal plates attached to a conductor (such as a heat sink or metal block) to dissipate heat from sensitive components or devices. Acting as a thermal bridge between the component and the ambient air, plate fins accelerate heat dissipation, typically featuring 1 to 2 fins per inch.

Common Applications of Stamped/Plate Fins
Stamped/plate fins are widely employed in various heat transfer systems, including:

  •  Air-cooled heat exchangers

  •  Oil coolers

  •  Radiators

  •  High-power electronics (e.g., computer processors, power amplifiers)

  •  Automotive and aerospace components (where weight and size are critical factors)

Construction and Design
In plate fin heat exchangers:

1.Tubes are arranged in parallel with uniform spacing to optimize fluid flow.

2.Plate fins are brazed to the tubes, forming a robust mechanical and thermal bond that ensures efficient heat transfer.

Key Advantages of Stamped/Plate Fins

1、Superior Heat Transfer Efficiency
The expanded surface area of plate fins maximizes heat exchange, that make them ideal for high-power applications with limited space.
2、Compact Design
They enable efficient heat dissipation in minimal footprints, crucial for aerospace and automotive industries where weight and size are constrained.
3、High Pressure Resistance
The brazed fin-tube structure allows higher working pressures compared to other heat exchanger types.
4、Cost-Effectiveness
Simple manufacturing processes (e.g., stamping and brazing) reduce production costs relative to complex fin designs.
5、Resilience in Harsh Environments
Plate fins are well-suited for sooting or fouling atmospheres due to:
A large surface area that balances heat transfer with fouling resistance.
A design that minimizes debris accumulation and is easier to clean than alternative exchangers.
 

Technical Note
The stamped/plate fin design combines thermal efficiency with structural durability, that make it a preferred choice for applications requiring reliable heat management in both clean and challenging operational environments.
