【摘要】：為研究磁力泵驅(qū)動兩相冷卻環(huán)路的工作特性,特別是啟動特性和換熱性能隨溫差的變化規(guī)律,搭建了磁力泵驅(qū)動兩相冷卻環(huán)路的實驗裝置,并利用空氣焓差法對其進行測試。結(jié)果表明:磁力泵驅(qū)動兩相冷卻環(huán)路啟動迅速,在600 s內(nèi)達到穩(wěn)定狀態(tài),受蒸發(fā)器內(nèi)液體過熱的影響,啟動過程中系統(tǒng)的壓力和溫度分布會產(chǎn)生微小波動;制冷量隨溫差的增大而增大,隨制冷劑質(zhì)量流量的增加呈先增大后減小的趨勢。溫差10℃時,系統(tǒng)最大制冷量為3.429 k W,能效比(EER)為12.94;溫差25℃時,制冷量最大為9.241 k W,EER為29.7。
[Abstract]:In order to study the working characteristics of two-phase cooling loop driven by magnetic pump, especially the law of starting characteristic and heat transfer performance varying with temperature difference, an experimental device of magnetic pump driving two-phase cooling loop was set up and tested by air enthalpy difference method. The results show that the two-phase cooling loop driven by magnetic pump starts rapidly and reaches a stable state within 600 s. Under the influence of liquid overheating in the evaporator, the pressure and temperature distribution of the system will fluctuate slightly during the start-up process. The cooling capacity increases with the increase of temperature difference, and increases at first and then decreases with the increase of mass flow rate of refrigerant. When the temperature difference is 10 鈩，
