An Experimental Study on Thermal Performance of Thermosiphons under Vibration Conditions

Abstract

Use of thermosiphon for airborne applications depends upon heat transfer ability under vibration conditions. To verify thermal performance of themosiphons, experimental investigations are carried out by attaching them to an X-band Transmit Receive Multi Module(XTRMM). Surface temperatures are measured. Comparative analysis is made with and without attachment of thermosiphons. Thermal performance is measured for thermosiphon at various inclinations. Two phase thermosiphons, copper filled with acetone with a fill ratio of 35-40% are used for experimentation. Experimental set up is subjected to random vibrations ranging from 20-2000Hz. Thermal and functional performance of XTRMM is checked for the same inclinations.
