摘要：
A theoretical model of few‐turn heat pipes is suggested. The equation for boiling liquid flow in a capillary of the pipe, which allows for the pressure difference of saturated vapor and for gravity and viscosity forces, is written. The parameters at which self‐oscillations of the liquid occur have been estimated. It is shown that the period of self‐oscillations is determined by the characteristic time of heat exchange between the liquid in the capillary and the surrounding medium. The time of self‐oscillations obtained theoretically is in good agreement with the experimental one.
