摘要

为研究磁力泵驱动两相冷却环路的工作特性

特别是启动特性和换热性能随温差的变化规律

搭建了磁力泵驱动两相冷却环路的实验装置

并利用空气焓差法对其进行测试。结果表明:磁力泵驱动两相冷却环路启动迅速

在600 s内达到稳定状态

受蒸发器内液体过热的影响

启动过程中系统的压力和温度分布会产生微小波动;制冷量随温差的增大而增大

随制冷剂质量流量的增加呈先增大后减小的趋势。温差10℃时

系统最大制冷量为3.429 kW

能效比(EER)为12.94;温差25℃时

制冷量最大为9.241 kW

EER为29.7。

Abstract

An experimental setup of two-phase cooling loop driven by magnetic pump was built. The performance and start-up characteristics of the two-phase cooling loop are evaluated by the air enthalpy difference method. Experimental results show that the two-phase cooling loop driven by magnetic pump presents excellent performance for energy saving. Its start-up is quick and the system reaches a steady state after 600 s. The fluctuations of pressure and temperature in the system are caused by the superheat of the liquid refrigerant in the evaporator during the start-up. The cooling capacity of the system increases with the temperature difference

and increases rapidly with the mass flow rate and then decreases slowly. When the temperature difference is 10℃

the maximum cooling capacity is 3.429 kW and the energy efficiency ratio is 12.94. When the temperature difference is 25℃

they reach 9.241 kW and 29.7

respectively.
