Research output: Contribution to journalArticlepeer-review


A thermal analysis of loop heat pipe (LHP) ground experiment chamber was carried out by building a physical model under the conditions of natural heat convection and heat radiation. The computation purpose is to achieve the thermal boundary conditions of the LHP space orbital positions in the ground to further secure LHP ground experiment in the coldest and the hottest cases. The general thermal design was made by determining the thermal chamber temperature, insulation, and refrigerant system. Analysis results show that inner chamber wall temperature should vary in the range of -62. 1°C to -10. 9 °C in order to realize the LHP space thermal conditions on ground experiment.
