针对当前 5G 通讯基站的散热需求，在一种印刷、滚压及吹胀工艺成形的铝质中空板壳基础上，采用真空、灌注、冷焊等工艺将其制造成一种吹胀型均热板，并研究该吹胀型铝质均热板在不同充注率、不同使用工况下的热阻及功率等传热性能参数。结果表明: 吹胀型铝质均热板在顺重力工况下的传热性能最优，在工质充注率 η = 10% 、传热功率 P = 60 W 时导热系数可达 19 900 W/( m·K) ，在 η = 5% 、P≥60 W 时烧干，在 η≥25% 、P≤10 W 时发生温度震荡现象; 在水平工况与逆重力工况下，该均热板的传热性能大幅下降，水平工况下的启动性能略差于逆重力工况，但在趋于稳定后传热性能略优。

Aiming at the urgent cooling demand of 5G base stations，a kind of Ｒoll bond Aluminum Vapor Chamber (RAVC) ，made from hollow aluminum substrate formed by printing，rolling，inflating，degassing，injecting and sealing processes，was prepared． The thermal performance of RAVC，such as thermal resistance and capacity，un- der different filling ratios and working conditions was investigated． The results indicate that RAVC shows best ther- mal performance under gravity working condition． The thermal conductivity can reach 19900 W/( m·K) when filling ratio is 10% and heating power is 60 W; RAVC reaches the heat transfer limit when filling ratio is 5% and heating power is over 60W; temperature oscillation occurs when filling ratio is over 25% and heating power is under 10W． Under horizontal and anti-gravity working conditions，RAVC's thermal performance becomes worse，and its start-up performance in horizontal state is better than that under anti-gravity working condition，but its thermal performance is not better until it becomes stable．
