This paper proposes a meters-class anti-gravity loop heat pipe with Shirasu Porous Glass(SPG) as a wick for the smart thermal management of house. SPG shows excellent capillary force against anti-gravity and high permeability based on submicron pore radius and porosity over 50 %. Furthermore, five layers PTFE filters which have low thermal conductivity were applied on the SPG wick to reduce the heat leak from the evaporator to the compensation chamber. The proposed anti-gravity LHP were designed and fabricated based on the one-dimensional steady-state numerical model. Experiments of heat load were conducted under 2 m and 4 m anti-gravity conditions and those results showed the stable operation. Finally, the LHP performance was evaluated by calculating the thermal resistance between the evaporator to the condenser.
