摘要

采用实验方法

研究了3种水力直径、2种工质(去离子水

连续相为去离子水、分散相体积分数为1%的FC-72/水乳液)、3种质量流量、不同壁面有效热流密度条件下微通道内的流动沸腾传热和压降特性

获得了不同条件下微通道内的归一化流动传热性能因子

并对典型流动沸腾工况下的流态进行了可视化测量。结果表明:向微通道内添加FC-72乳液分散相后

分散相的沸腾扰动使得气泡更容易脱离壁面

导致核态沸腾提前、换热强化

但换热强化效果随着壁温的增加而减弱。当微通道高度分别为217、433 μm时

相对于去离子水工质

添加FC-72乳液分散相

可使微通道内的换热系数分别增加63.8%、103.5%

但微通道内压降略有增加。随着壁温的增加

压降先减后增、换热因子先增后减。当微通道内连续相产生核态沸腾时

换热因子达到极大值

微通道高度分别为217、433 μm时

其流动换热因子极值分别为1.41和1.91。

Abstract

The flow boiling heat transfer and pressure drop characteristics in a micro-channel heat sink were studied through experimental tests at three hydraulic diameters

on two different fluids(pure deionized water and 1% FC-72/water emulsion)

at three mass flow rates and a range of effective wall heat flux. The normalized flow and heat transfer performance factors of the micro-channel heat sink with different fluids were obtained under various conditions. The flow patterns on the heated wall of the micro-channel under typical flow boiling conditions were visualized. The results show that the introduction of FC-72/water emulsion dispersive phase into the micro-channel makes the bubbles more easily escape from the wall due to the disturbance of dispersive phase boiling

which makes nuclear boiling occur in advance and enhances heat transfer on the heated wall. However

the heat transfer enhancement on the targeted wall decreased as wall temperature increases. For micro-channels with 217 μm and 433 μm in heights

compared with the cases of pure deionized water

the heat transfer coefficient increased by 63.8% and 103.5% respectively if 1% FC-72/water emulsion was adopted. But the pressure drop in the micro-channel increased slightly. As the wall temperature increased

the pressure drop in the micro-channel decreased at first and then increased

while the normalized flow-heat transfer factor increased at first and then decreased. If the continuous phase of FC-72/water emulsion achieves the nuclear boiling

the normalized flow and heat transfer performance factor would reach the maximum value. In this study

the measured maximum values of the normalized flow-heat transfer factor equal to 1.41 and 1.91 for the 217 μm and 433 μm micro-channel

respectively.
