摘要

受望天树叶脉结构启发，在普通二级分支（MHE-SS）基础上设计了仿生二级分支（MHE-BS）、完全五级分支（MHE-CVB）和不完全五级分支（MHE-IVB）3种不同结构的微通道换热器。采用ANSYS FLUENT软件模拟20 ℃的冷却水在不同入口雷诺数（

=660.07、990.10、1 320.13）下进入施加恒定热流密度50 kW/m

的4种换热器结构，对比分析了不同工况下的流动特性、温度特性和综合传热性能。研究表明：多级仿生通道结构能够显著提高换热器综合传热性能，在不同工况下MHE-CVB相比于MHE-SS进出口压降下降均超过35%、传热面温度下降均超过2 ℃、综合传热性能强化因子均大于1.2。

Abstract

Microchannel heat exchangers

including a bionic secondary branch (MHE-BS)

complete vein bionic branch (MHE-CVB)

and incomplete vein bionic branch (MHE-IVB)

were designed based on the straight secondary branch (MHE-SS) inspired by the leaf vein structure of

Parashorea chinensis

. ANSYS FLUENT software was utilized to simulate the flow and temperature characteristics of 20 ℃ cooling water entering these heat exchanger structures under a constant heat flux of 50 kW/m

at different inlet Reynolds numbers (

=660.07

990.10 and 1 320.13). The research findings indicate that multistage bionic channel structure can significantly enhance the overall heat transfer performance of the heat exchanger

with MHE-CVB showing more than a 35% reduction in inlet and outlet pressure drop compared to MHE-SS under different working conditions. In addition

it showed an decrease in surface temperature by over 2 ℃ and a strengthening factor for comprehensive heat transfer performance exceeding 1.2.
