Heat</strong> <strong>pipes</strong> <strong>are</strong> <strong>widely</strong> <strong>used</strong> <strong>as</strong> <strong>devices</strong> <strong>that</strong> <strong>allow</strong> <strong>the</strong> <strong>transfer</strong> <strong>of</strong> <strong>significant</strong> <strong>heat</strong> <strong>flows</strong> <strong>to</strong> <strong>solve</strong> <strong>various</strong> <strong>problems</strong> <strong>in</strong> <strong>power</strong> <strong>plants. Equipment</strong> <strong>using</strong> <strong>heat</strong> <strong>pipes</strong> <strong>can</strong> <strong>be</strong> <strong>found</strong> <strong>in</strong> <strong>the</strong> <strong>thermal</strong> <strong>power</strong> <strong>complex, metallurgy, aviation</strong> <strong>and</strong> <strong>rocket</strong> <strong>and</strong> <strong>space</strong> <strong>technology.</strong> <strong>Complex</strong> <strong>heat-mass</strong> <strong>exchange</strong> <strong>processes</strong> <strong>of</strong> <strong>boiling, evaporation, condensation, movement</strong> <strong>of</strong> <strong>the</strong> <strong>liquid</strong> <strong>phase</strong> <strong>in</strong> <strong>porous</strong> <strong>or</strong> <strong>capillary</strong> <strong>structure</strong> <strong>stake</strong> <strong>place</strong> <strong>inside</strong> <strong>the</strong> <strong>heat</strong> <strong>pipe. Existing</strong> <strong>methods</strong> <strong>of</strong> <strong>calculation</strong> <strong>and</strong> <strong>design</strong> <strong>are</strong> <strong>often</strong> <strong>of a recommendatory</strong> <strong>nature. The</strong> <strong>complexity</strong> <strong>of</strong> <strong>heat</strong> <strong>pipe</strong> <strong>work</strong> <strong>processes</strong> <strong>prompts</strong> <strong>scientists</strong> <strong>in</strong> <strong>the</strong> <strong>field</strong> <strong>of</strong> <strong>heat</strong> <strong>and</strong> <strong>mass</strong> <strong>transfer</strong> <strong>to</strong> <strong>further</strong> <strong>scientific</strong> <strong>research. In</strong> <strong>this</strong> <strong>work, a series</strong> <strong>of</strong> <strong>experimental</strong> <strong>studies</strong> <strong>is</strong> <strong>conducted</strong> <strong>on</strong> <strong>the</strong> <strong>modeling</strong> <strong>of</strong> <strong>work</strong> <strong>processes</strong> <strong>in</strong> <strong>the</strong> <strong>middle</strong> <strong>of</strong> <strong>heat</strong> <strong>pipes, namely</strong> <strong>the</strong> <strong>influence</strong> <strong>of</strong> <strong>vibrations</strong> <strong>and</strong> <strong>the</strong> <strong>angle</strong> <strong>of</strong> <strong>inclination</strong> <strong>on</strong> <strong>the</strong> <strong>intensity</strong> <strong>of</strong> <strong>heat</strong> <strong>exchange.</strong> <strong>This</strong> <strong>work</strong> <strong>is a generalization</strong> <strong>of</strong> <strong>experimental</strong> <strong>data</strong> <strong>on</strong> <strong>the</strong> <strong>study</strong> <strong>of</strong> <strong>the</strong> <strong>influence</strong> <strong>of</strong> <strong>vibrations</strong> <strong>and</strong> <strong>the</strong> <strong>angle</strong> <strong>of</strong> <strong>inclination</strong> <strong>on</strong> <strong>the</strong> <strong>characteristics</strong> <strong>of</strong> <strong>heat</strong> <strong>pipes.</strong></p> ER -
