摘要
针对算力服务器GPU模块功率突破1 kW级别的热管理难题，本文基于高效浸没液冷方案，开展了GPU模块的液冷结构设计。通过构建三种不同浸没液冷结构下的三维稳态流动与传热模型，数值分析了GPU芯片的温度响应特性及流场分布规律。研究结果表明：集成三维均热板与射流结构的方案展现出最优的散热性能。在相同工况条件下，该方案相较于传统冷板方案，可使GPU芯片最高温度降低约48.68 ℃；相较于未集成射流结构的浸没方案，则可进一步降低约3.85 ℃，同时有效改善了模块内部的温度场与流场分布。
Abstract
To address the thermal management challenge of computing server GPU modules whose power exceeds the 1 kW level, this paper develops a liquid cooling structure design for GPU modules based on an efficient immersion liquid cooling scheme. By constructing three-dimensional steady-state flow and heat transfer models for three different immersion liquid cooling configurations, the temperature response characteristics of the GPU chip and the flow field distribution are numerically analyzed. The results show that the configuration integrating a three-dimensional vapor chamber with a jet structure exhibits the optimal heat dissipation performance. Under the same operating conditions, this configuration reduces the maximum temperature of the GPU chip by approximately 48.68? C compared with the traditional cold plate scheme, and by about 3.85? C compared with the immersion scheme without the integrated jet structure. Furthermore, it effectively impStructural design of immersion liquid cooling for the gpu module of a computing serverroves the temperature field and flow field distribution inside the module.关键词
