Loop heat pipes (LHPs) are two phase heat transfer devices that use evaporation and condensation of a working fluid to transfer the heat and use the capillary force developed in fine porous wick to circulate the fluid. They possess all the main advantages of conventional heat pipes, but owing to the original design and special properties of the capillary structure are capable of transferring heat efficiency for distances up to several meters at any orientation in the gravity field, or to several tens of meters in a horizontal position. They do not require any electrical energy for heat transport because of the absence of any mechanical moving parts. The main objective of this project is to fabricate a 2m long loop heat pipe for efficient transfer of heat. The main parts include a wick, a heater block, an accumulator, 2m long copper wire and a condenser. An external fan was introduced to speed up the natural condensation process. The wick was made with copper with 0.3 mm micro drilled pores. The working fluid used is ethanol. After fabricating the model, the pipe was completely filled with ethanol and temperature readings were noted using a temperature sensor at two different positions. A good agreement was reached between the two values.
