There have been various of set-ups for the filling of ammonia to heat pipes existing in the literature. In one of these set-ups , the anhydrous ammonia is evaporated from the ammonia tank and condensed inside an intermediate tank whose mass is measured. Then, the ammonia inside the intermediate tank is evaporated and sent to the heat pipe, which is cooled simultaneously. The necessity of extra tank, heating-cooling means and relatively long dwell time for the filling of the required ammonia are the disadvantages of this application. On the other hand, in another filling solution, ammonia is cooled in a tank (by means of liquid nitrogen most of the time) and turned into liquid phase. Then it is sent to the heat pipe in the form of liquid. In this application, the complexities arise due to the extra tank, liquid nitrogen tank and vacuum isolated pipes required for liquid nitrogen transport. Moreover, flowmeter and metering pump are needed to determine exact mass of the liquid ammonia inside the heat pipe.
