Model No:HT-2462
The apparatus consists of three pipes, viz. A heat pipe, copper pipe and stainless steel pipe. Ail the pipes have same physical dimensions. Copper and stainless steel pipes serve the purpose of comparison of heat pipe performance. All pipes are mounted vertically with a band heater at lower end and water filled heat sink at upper end. Nearly isothermal operation of heat pipe is clearly seen from longitudinal temperature distribution of the pipe.
