HEAT TRANSFER DEVICE Russian patent published in 2021 - IPC F28D15/04 

FIELD: heat engineering.

SUBSTANCE: invention relates to heat engineering and can be used in heat transfer devices. Heat transfer device, including a two-phase loop thermosyphon, consisting of an evaporator and a heat exchanger filled with a working fluid, made in the form of separate chambers, the upper parts of which are communicated by means of a steam line, the lower ones - by means of a condensate line. The evaporator is completely filled with the working fluid, the hydraulic accumulator is partially filled with the working fluid, the hydraulic seal is completely filled with the working fluid. The heat exchanger is located above the evaporator at a distance that ensures the transport of vapor of the working liquid along the steam line from the evaporator to the heat exchanger, in which the internal volume is greater than the liquid volume of the condensing vapor of the working liquid. The level of the working fluid in the accumulator is in the range from 1/3 to 2/3 of the height of the accumulator, moreover, the working fluid in the evaporator and the accumulator at the beginning of work are at the same level, and during operation the level of the working fluid in the evaporator fluctuates within the limits of the change in the level of the working fluid in the accumulator. The hydraulic seal is located below the evaporator and is made in the form of pipe coils similar to the steam pipe of the working fluid vapor, while the number of bends in the hydraulic seal pipe must exceed the number of bends in the steam pipe of the working fluid.

EFFECT: increasing the reliability and service life.
