Methods of Increase of the Evaporators Reliability for Loop Heat Pipes and Capillary Pumped Loops

In this paper there are considered some differences between the Loop Heat Pipes (LHPs) and the Capillary Pumped Loops (CPLs) performances. There offered the methods of the capillary evaporators reliability function increasing for two-phase systems of the LHP and the CPL type. The reliability increasing of above mentioned systems evaporators is proposed to be done by using of composite wicks and/or thermal electrical coolers. The recommended means could decrease the probability or except completely the “vapor blocade” of absorbing surface of evaporators capillary pumps.
