Mini-LHP is a two phase heat transport device that is being considered both for terrestrial and space thermal management applications. Mini-LHPoperates on a closed cycle vaporization of a working fluid at the evaporator followed with heat rejection by condensation in the condenser. The fluid flow is sustained by the menisci formed in the porous wick of the evaporator where the heat dissipating device is mounted. The mini-LHP is designed and developed at ISRO Satellite centre, Bangalore. Thermal performance test at different heat loads has been conducted on mini-LHP. Thermal performance of the mini-LHP is satisfactory and results are presented in this paper.
