绝热段阻力对CO2、R134a和R410A分离式热管传热性能的影响OA北大核心CSTPCD
Effect of Flow Resistance in Adiabatic Part on the Thermal Performance of CO2,R134a,and R410A Two-phase Thermosyphon Loops
通过实验研究了上升管和下降管阻力对CO2、R134a和R410A分离式热管传热性能的影响,分析了热管传热极限和传热热阻的变化规律.研究发现阻力变化对不同工质热管的影响不同,对于CO2热管,上升管阻力和下降管阻力对其传热性能的影响程度接近,当上升管或下降管阀门开度从90°降至30°时,CO2热管的传热极限均由1 200 W降为700 W.对于R134a和R410A热管而言,上升管阻力对其传热性能的影响更大,当上升管阀门开度从90°降至30°时,R4…查看全部>>
This study experimentally investigates the impact of flow resistance in risers and downcomers on the heat transfer performance of two-phase thermosyphon loops(TPTLs)with CO2,R134a,and R410A refrigerants.Variations in the heat transfer limit and thermal resistance of the TPTLs were analyzed.The results show that the three TPTLs respond differently to changes in flow resistance.For the CO2 TPTL,the effects of the riser and condenser resistances on thermal perf…查看全部>>
