Heat Pipe Demonstrator

The apparatus enables the students to study the interesting phenomenon of heat pipe & to compare its performance with other pipes. The apparatus consists of a heat pipe made up of stainless steel, evacuated and partially filled with distilled water, a copper pipe and stainless steel pipe of same sizes. The pipes are heated at one end and water tank is provided at other end of pipes to take over heat. Thermocouples are provided along the length of pipes so that nearly isothermal operation of heat pipe as compared with other conductors can be demonstrated. Rapid rise of water temperature in tank around heat pipe demonstrates super conductivity of heat pipe as compared to copper and stainless steel pipe.

Specifications:

• Heat Pipe - Stainless steel pipe size 25 mm dia., 300 mm. long with both side closed,evacuated and filled with distilled water.
• Copper Pipe - 25 mm dia., 300 mm. long.
• Stainless Steel pipe - 25 mm dia., 300 mm. long.
• All pipes are positioned horizontal with one end heated by band heater and water tank at other side.
• Thermocouples are provided along the length to all pipes.
