Pin-Fin Heat Sink Test Rig for Electronics Cooling

Approx. component budget: Rs. 6,000 - 10,000

Objective

Compare fin patterns for heat transfer and thermal resistance at different airflow speeds.

What you will build

Aluminium plates with different fin patterns, an electric heater block, a duct with a fan and temperature sensors.

Results you can expect

• Thermal resistance vs airflow
• Effect of fin pattern
• Fan power vs cooling benefit

What you will learn

Convection and heat sink design, needed in EV and electronics industries.

Tools and notes

Arduino, thermocouples, anemometer. Fin samples can be cut or bought ready-made.

Resume points from this project

• Built and tested Pin-Fin Heat Sink Test Rig for Electronics Cooling; objective: compare fin patterns for heat transfer and thermal resistance at different airflow speeds.
• Measured and analysed thermal resistance vs airflow and Effect of fin pattern; wrote the report and presented the results in a viva. Add your own numbers: [x].

Replace [x] with your own measured results. Write only what you really did.
