Zakharchenko O. The heat transfer characteristics of heat exchangers on the evaporative thermosyphons serpentine type base.

The dissertation is devoted to study the basic operation characteristics of heat exchangers on the evaporative thermosyphons serpentine type base. The experimental researches by definition maximal heat ability of the thermosyphon of the capillary type (din=2-4 mm) with the organized and unorganized circulation of the working liquid are resulted. The factors influencing on a critical heat flow are determined. The investigated modes of operations and thermodynamic phenomena in capillary thermosyphon are compared with the known data for the large sizes thermosyphon (din>6 mm). The designs of the heat exchangers of gas - gas type and the heat transfer device for temperature stabilization of the radioelectronic equipment on evaporative thermosyphons serpentine type base are developed and the experimental researches were provided. Based on results of experimental researches the basic heat transfer characteristic and thermal modes these devices are determined. The constructive - technology factors influencing for operating ability these devices are revealed.
