Abstract

The invention relates to electrohydrodynamic heat pipes and can be used as power source.The electrohydrodynamic heat pipe includes a casing (1) with an evaporation zone (2) in the lower part, a condensation zone (3) in the upper part and a channel (4). Between the condensation zone (3) and the channel (4) is placed a partition wall (9), to which are attached two steam lines (10), a central condensate line (16) and two lateral condensate lines (7), whose upper ends communicate with the condensation zone (3), at the same time the upper end of the central condensate line (16) is mounted above the upper ends of the lateral condensate lines (7), and its lower end is mounted inside a capillary structure (11), placed in the evaporation zone (2). The heat pipe further includes two cylindrical metal capacities (13), placed outside the casing (1), each of which is provided on the outside with a dielectric sheath (14). In the upper part the capacities (13) communicate with the opposite ends of the lateral condensate lines (7), fitted with nozzles (8), and the lower part of capacities (13) communicates through pipelines (17) with the capillary structure (11). The lateral condensate lines (7) and the pipelines (17) are provided with dielectric substrates (12). Inside the capacities (13), below the nozzles (8), is installed an ionizing electrode (5) and a charge collector (6), made in the form of grid, each of which is connected to the metal body of the capacity (13), at the same time each ionizing electrode (5) is connected through high-voltage connectors 15) to the metal body of the opposite capacity.
