翻转角度对雷达阵面翻转式插箱空调热管理影响的实验研究

To cnsure that the thermal management System functions effectively during changcs in gravitational flipping angle during the work process of the radar antenna array, a rotatable plug-in box-typc air conditioning experimental rig is developcd. Through the Simulation of the working process of the radar antenna array, the dynamic operating characteristics of the rotatable plug-in box-type air conditioners arc analyzed. Variations in System Performance under different tilt angles are determined, and the dynamic distribution of refrigerant and its impact on electronic device thermal management is investigated. The rcsults demonstrated that the air conditioning System remains highly rcliablc under tilted conditions. Compared to the non-tilted State, the System showed minor Performance decreases but maintained stable Operation under the flipping working condition. The maximum reduetions in cooling capacity for forward and backward tilts of 90° wcrc 0. 29% and 6. 48% > respectively, while the maximum reductions in the coefficient of Performance wcrc 4. 11% and 6. 02%, respectively. Furthermorc, the refrigerant distribution is highly affected by gravity; forward and backward tilts of 90° rcsultcd in uncvcn refrigerant distribution within the evaporator, whereas left and right tilts of 90° had ncgligiblc effects. These findings offer theoretical and practical reference for the design and application of plug-in box-type air conditioning Systems for radar arrays.
