FIELD: power industry. ^ SUBSTANCE: blower contains cylindrical housing 1 inside which there located is evaporation, working and condensing chambers 8, 10, 15. End walls 2, 3 are connected by means of central wick 4 covered with shell 5 so that gaps 6, 7 are formed at walls 2, 3 and passing along central axis. In evaporation and condensing chambers 8, 15 the inner surface of side wall and end walls 2, 3 are covered with grid 16 made from thin layer of porous material and connected in the centre of end walls 2, 3 with central wick 4. Inside working chamber 10 there are power turbines 11,12 which are coaxially located one after another, rigidly attached to inner surface of its wall and outer surface of shell. On outer surface of working chamber 10 there is impeller 13. Outer housing 17 covering impeller 13 is helical. ^ EFFECT: increasing efficiency of heat-pipe centrifugal blower. ^ 2 dwg |
