P 31 Pastukhov, V. G. Combined LHP and PHP based heat-transfer system / V. G. Pastukhov, Yu. F. Maydanik // International Journal of Thermal Science. - 2013. - Vol.74. - С. 81-85 Рубрики: ФИЗИКА Кл.слова (ненормированные): HEAT-TRANSFER SYSTEM -- LOOP HEAT PIPE -- PULSATING HEAT PIPE Аннотация: The paper presents the results of development and experimental investigation of a heat-transfer system consisting of a pulsating and a loop heat pipe. The pulsating heat pipe (PHP) was made of a copper capillary tube 2 mm in diameter and located on an aluminum plate measuring 260 × 200 × 1 mm, had a thermal contact with the evaporator interface of a loop heat pipe (LHP) 0.6 m long. The working fluid of the PHP was R141b. The LHP was filled with ammonia. A heat-load source measuring 200 × 200 mm was located on the PHP, and its heat was transferred to the LHP evaporator. Tests were conducted at different orientations in the gravity field at heat loads from 10 to 170 W and heat-sink temperatures from −20 to +20 °C. A minimum value of thermal resistance equal to 0.28 °C/W was achieved in the heat load range from 50 to 90 W. |
