HEAT-TRANSFER TWO-PHASE LOOP (VERSIONS) Russian patent published in 1998 - IPC

FIELD: cooling systems of heat-generating devices. SUBSTANCE: according to first version, loop includes evaporators and condenser interconnected by means of steam and condensate pipe lines and reservoir connected with condensate pipe line by means of individual pipe line. Cold junction of each thermoelectric microrefrigerator is connected with respective supply passages of capillary pumps by means of additional thermal pipes and hot junction is connected with heat supply zones of evaporator directly or by means of heat line, for example, thermal tube. According to second version, heat-transfer two-phase loop has two evaporators equipped with thermoelectric microrefrigerators whose hot junctions are connected with heat supply zone of evaporator and cold junctions are connected with part of condensate pipe line adjoining directly the capillary pump. This section of condensate pipe line is connected with supply passages with the aid of additional capillary structure. EFFECT: enhanced operational reliability of evaporators in case of change in condition in heat supply and or heat removal zones at irregular or inconstant distribution of thermal load on evaporators and in other transient when drainage of evaporators is likely to occur. 6 cl, 4 dwg
