Heat Pipe Performance Study: Heat Load and Tilt Angle

Approx. component budget: Rs. 7,000 - 12,000

Objective

Find the thermal resistance of a heat pipe at different heat loads and tilt angles and compare it with a solid copper rod.

What you will build

Ready-made copper heat pipes clamped to a heater block with an aluminium fin stack and a small fan, thermocouples along the pipe, and a plain copper rod of the same size as the reference.

Results you can expect

• Temperature profile along the pipe
• Thermal resistance vs heat load
• Effect of tilt angle
• Comparison with the copper rod

What you will learn

Two-phase heat transfer, thermal resistance, effect of orientation, and why heat pipes are used in laptops and LED lights.

Tools and notes

Arduino + thermocouples, heater with a dimmer or regulated supply, Excel. Insulate the heater block and use proper electrical protection.

Resume points from this project

• Built and tested Heat Pipe Performance Study: Heat Load and Tilt Angle; objective: find the thermal resistance of a heat pipe at different heat loads and tilt angles and compare it with a solid copper rod.
• Measured and analysed temperature profile along the pipe and thermal resistance vs heat load; 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.
