“…Numerical investigations regarding the geometry of the porous wick have been reported in the past [8,9], but are related to axial grooves manufactured in the evaporator's body inner diameter and the random distribution of pores in the wick material. Important contributions related to improving capillary structures to result in better thermal performances for LHPs have also been reported [10,11] and are extensively applied by many researchers. Some features applied to improve LHPs thermal performance, such as microgrooves machined on the evaporator's inner diameter, have been reported earlier [12,13], which could be implemented in several other designs with a relative increase on the device's thermal performance [2].…”

“…However, they failed to consider the parameters of the manufacture of the wick. Kiseev et al [3] discussed the method of increasing the heat transfer performance by setting the manufacturing parameters of the wick use in the LHP. Kaya et al [4] examined the parameters in various experiment operational characteristics for an LHP.…”

This investigation studies the effect on pressure of the filling volume rate in a manufactured nickel powder capillary structure (wick) for a loop heat pipe (LHP). The filling volume ratio is an index of pressure from 1 to 1.3 to investigate the influence on filling weights of the internal parameters of a wick (permeability, effective pore radius and porosity) and heat transfer performance for LHP. The wick is manufactured, based on the standard and non-pressurized filling weights in the manufactured wick mold. The conversion of a pressure change to a weight change used to investigate the relationship between the change in filling volume of pressure to the internal parameters of the wick and the heat transfer performance. As the filling volume rate increases, the capacity of the wick increases, but an excessive filling volume rate makes the wick too dense, affecting its permeability and heat transfer performance in LHP. An experimental test demonstrates that the permeability and heat transfer performance are optimal at a filling volume ratio of 1.2.
