2. a kind of screw pump power heat pipe according to claim 1 it is characterised in that screw pump power heat pipe worked
Cheng Shi：
The upper shell (14) of screw pump power heat pipe is condensation segment, and lower shell (2) is evaporator section, and middle shell (8) is adiabatic section；Heat
Pipe working media collects in lower shell (2) lower end and forms work liquid pool；Wick (1), throttling wick (5) are adsorbed with heat pipe work
Make medium；During the work of screw pump power heat pipe, evaporator section absorbs heat from heat source, and heat makes to be soaked in imbibition by lower shell (2)
Work medium for heat pipe evaporation in core (1), the stator winding of stator component (9) connects alternating current power supply, and stator component (9) produces rotation
Turn magnetic field, the magnetic line of force of the mouse cage sliver cutting stator rotating excitation field of the mouse cage (11) of rotor part produces induction torque, rotor
Part enters asynchronous operation state；During impeller (7) rotation, blade (32) lower edge is mutual with guide vane (22) upper end-face edge
The impeller inner chamber constituting between effect, and the impeller propeller boss (31) of impeller (7), blade (32), impeller duct (33) axially cuts
Face is gradually reduced from bottom to up, during impeller (7) rotation, the work medium for heat pipe steam of evaporator section inner chamber is delivered in condensation segment
Chamber；The work medium for heat pipe steam that impeller (7) conveys sequentially passes through pod apertures (18), Venturi tube (13) flows to condensation segment inner chamber
Upper end, work medium for heat pipe steam flows downward along upper shell (14) inner radial surface from condensation segment inner chamber upper end, cooling stream
Body, by the heat of upper shell (14) absorption condensation section inner chamber work medium for heat pipe steam, makes a part of work medium for heat pipe steam
It is condensed into liquid in upper shell (14) inner surface of condensation segment inner chamber, meanwhile, Venturi tube (13) induces in a part of condensation segment
The work medium for heat pipe steam of chamber lower end flows up through Venturi tube (13), and Venturi tube (13) makes in condensation segment inner chamber
Work medium for heat pipe steam circulation flows, and promotes the condensation of condensation segment inner chamber work medium for heat pipe steam, Venturi tube (13)
Increased the heat exchange area of condensation segment simultaneously；Condensed work medium for heat pipe flows downwardly in throttling wick (5), and throttling is inhaled
Wick-containing (5) makes condensation segment inner chamber relative closure, impeller duct (33) the lower end radial outside edge of impeller (7) and conduit (6)
Gap between catheter body (23) inner radial surface is little, also makes condensation segment inner chamber relative closure, maintains the steaming of condensation segment inner chamber
Steam pressure；The work medium for heat pipe steam of impeller (7) compression condensation section inner chamber, the work medium for heat pipe vapour pressure of condensation segment inner chamber
Power and temperature improve simultaneously, and the work medium for heat pipe steam pressure of evaporator section inner chamber reduces, and promote evaporator section inner chamber heat further
The evaporation of pipe working media；Under the promotion of condensation segment inner chamber steam pressure, it is attracted in throttling wick (5) pore
Work medium for heat pipe flows downwardly into evaporator section inner chamber, forms the cycle of operation of work medium for heat pipe.
