摘要：

为探究并行流道液冷板的散热性能，采用计算流体力学（CFD）数值计算方法对液冷板进行三维稳态分析，对比研究了液冷板在不同冷却液流量、流道宽度、流道深度和强化传热结构下的散热性能、均温性能以及能耗性能。结果表明：增加流量在一定程度上可以提升液冷板的散热性能，但持续增大流量不仅会增加系统能耗，而且改善效果十分受限。流道宽度从中心向两侧递减变化、流道深度减小、布置强化传热结构的设计都有利于提高液冷系统的散热和均温性能；相对于等宽（A₅）流道设计，整体布置强化传热结构（S₁）的流道设计可使液冷板的平均温度和最大温差分别降低8.9 ℃和9.06 ℃。本文研究成果可为电池热管理系统的结构设计提供理论指导。

Abstract:

In order to study the thermal dissipation performance of a liquid-cooled plate with parallel channels， the three-dimensional steady-state analysis was performed by using CFD method. The effects of coolant flow rate， channel width， depth and layout of enhanced heat transfer structure on the performances of a liquid-cooled plate were contrastively investigated， including the thermal dissipation， the uniform temperature and energy consumption. The results indicate that the thermal dissipation performance is improved by increasing the coolant flow rate， but excessive flow rate leads to increased energy consumption and limited improvement effect. Designs of decreasing channel width from the center to two sides， decreasing channel depth and adding enhanced heat transfer structure are all beneficial to the thermal dissipation and temperature uniformity of the liquid cooling system. In addition， the design of wholly added enhanced heat transfer structure （S1） reduces the average temperature and maximum temperature difference by 8.9 °C and 9.06 °C respectively， compared with the design of equivalent channels width （A5）. The conclusions provide a theoretical direction for structural design of battery thermal management system.

Key words: vehicle engineering, liquid cold plate, parallel channel, thermal dissipation performance, energy consumption, enhanced heat transfer structure
