Heat-transfer unit

摘要

The heat-transfer unit contains an evaporation chamber (1) having a coaxially arranged evaporator (3) consisting of capillary material, which is in thermal contact with a heat source, and possesses an axial longitudinal channel (7) having a transverse partition wall (14) consisting of capillary material, a steam-jet pump (13) and a heat-exchange chamber (4). Two cavities (5 and 6) are provided on the end faces in the evaporation chamber (1). The partition wall (14) is adjacent to the end face of the evaporator (3) and has through-bores (16) and a diametral channel (11) which is connected to the nozzle (12) of the steam-jet pump and to a steam collector (10). The collector (10) is connected to steam derivation channels (9) which are formed on the outer surface of the evaporator (3) and which are located between cylindrical collars (22). The zone of the heat-exchange chamber (4) containing the heat-exchange medium of reduced heat content is connected to the suction space of the steam-jet pump (13) by means of a pipeline (20), whilst the zone containing the heat-exchange medium of increased heat content is connected to the delivery space (15) of the pump (13) by means of a pipeline (21). <IMAGE>
