Abstract: Abstract. - Conceptual design of flat-plate collector (FPC) with integrated solar-powered pump (SPP) has been carried out. SPP represents simple heat engine - membrane pump operating through alternating of processes of evaporation and condensation in its working chamber. It should provide circulation of water using part of absorbed by FPC heat returning it finally to the same heat carrier. Two basic versions of structural layout of FPC have been considered: the first - with flow-through absorber (with circulation of water through riser pipes welded to absorbing plate) and the second – with absorber with gravity-assisted heat pipes (GAHPs). Important role of proper organization of boiling heat transfer on downward-facing heating surface of working chamber, in terms of efficient operation of SPP, is stated. Thermo-hydrodynamic peculiarities of this process are considered. The ways of improvement of reliability and efficiency of SPP are outlined.
