Abstract: | Development in the design and thermal performance of the loop heat pipes (LHPs) demands the corresponding improvement in the
theoretical modeling capabilities of these devices. In this paper, mathematical model for assessing the thermal performance
of the miniature LHPs (mLHPs) on the basis of the operating temperature and thermal resistance of the loop has been discussed
in detail. In order to validate the theoretical model, a mLHP with the flat disk shaped evaporator, 30 mm in diameter and
10 mm thick, was developed and tested with nickel and copper wick structure. By comparison with experimental results, it was
found that the theoretical model was able to predict the evaporator temperature and loop thermal resistance very well and
within the uncertainties imposed by the underlying assumptions. The mathematical model can be used to validate the design
of the mLHP and verify whether the proposed design is consistent with the maximum heat load capacity required for the intended
application. In addition to this, the model can assists in understanding and refining the outcomes of the experimental studies. |
