摘　　要：为了解决气泡泵效率低、不能有效利用低品位不稳定热源等缺点,提出了一种导流式气泡泵,并对其提升性能进行了实验研究。在给定运行条件下,研究不同加热功率和沉浸比对液体提升量的影响,给出了实验曲线,并与传统气泡泵进行了对比分析。实验结果表明:当提升管直径为16mm,沉浸比为0.4时,导流式气泡泵的启动功率可降低100W,提升效率最高可提高13%,证明导流式气泡泵具有启动功率低、效率高、节能等显著特点,分析结果对气泡泵效率的提升以及Einstein循环制冷机性能的提高具有重要的意义。In the light of such demerits of a bubble pump as low in efficiency and incapable of effectively utilizing low quality unsteady heat source etc.,presented was a flow guided bubble pump with its lifting performance being experimentally studied.Under a given operation condition,the influence of various heating powers and immersion ratios on the liquid lifting quantity was also investigated.The test curves were given and compared with those of the traditional bubble pumps.The test results show that when the diameter of the lifting tube is 16 mm and the immersion ratio is 0.4,the startup power of the flow guided bubble pump can decrease by 100 W and the lifting efficiency can increase by 13%,proving that flow guided bubble pumps are characterized by such remarkable features as a low startup power,high efficiency and energy-saving etc.The analytic results are of major significance for enhancing the efficiency of a bubble pump and the performance of an Einstein cycle refrigerator.
