摘要

为探究微肋与二次通道复合结构对微通道换热器流动换热性能增强的影响机理

采用数值方法

研究了不同雷诺数下6种带肋复合微通道换热器内的压降、流场结构、摩擦系数、基底温度、相对努赛尔数和综合流动换热性能

并与矩形光滑微通道和无肋二次通道微通道的流动换热性能进行了对比。研究表明:在流动特性方面

引入二次通道结构对微通道内的压降损失和相对摩擦系数没有影响

但引入微肋结构会产生节流效应并诱发漩涡结构

导致微通道内的压降损失增大3～10倍; 在传热特性方面

引入二次通道结构能够强化换热

在二次通道结构基础上增加微肋结构能进一步增强微通道换热器的传热性能; 相比于矩形光滑微通道和无肋二次通道微通道

复合微通道换热器的基底温度最高下降13.52 K

相对努塞尔数最高增大35.36%; 在综合性能方面

对于所研究的6种带肋复合微通道换热器

前三角肋复合微通道具有最优的流动传热综合性能

并具有高流速、低泵功率、低热阻等优点。

Abstract

To explore the effect of composite structure of micro-ribs and secondary channel on the enhancement of flow and heat transfer performance in micro-channel heat sinks

the numerical method is utilized to investigate the pressure drop

flow structure

friction factor

base temperature

relative Nusselt number

and comprehensive flow and heat transfer performance in the heat sinks of six different ribbed composite micro-channels at a range of Reynolds numbers. The flow and heat transfer performance in the composite micro-channel heat sinks are compared with those in the rectangular smooth micro-channel and the non-ribbed micro-channel with secondary channel. The results show that

with respect to the flow characteristic

the introduction of the secondary channel has no effect on the pressure drop penalty and the relative friction coefficient in the micro-channel. However

the introduction of the micro-ribs produces a throttling effect and induces vortex structures

resulting in an increase of 3—10 times in the pressure drop penalty in the micro-channel. For the heat transfer characteristic

the introduction of the secondary micro-channel enhances the heat transfer in the micro-channel

and the micro-ribs in addition to the secondary micro-channel can further improve the heat transfer. Compared with the rectangular smooth micro-channel and the non-ribbed micro-channel with secondary channel

the base temperature in the composite micro-channel heat sink is decreased by 13.52 K and the relative Nusselt number is increased by 35.36% at most. In terms of the comprehensive performance

among the six ribbed composite micro-channel heat sinks studied

the composite micro-channel with front triangular ribs has the best comprehensive flow and heat transfer performance

and the advantages such as the high flow velocity

low pump power consumption

and low heat resistance.
