摘　　要：为分析粉末烧结型铝制均温板在旋转离心力作用下传热性能的变化,文中设计了旋转试验测试平台,用以模拟不同转速过载条件,测试均温板在静止、低转速、高转速等状态下的传热温差,并进一步研究记录转速变化时均温板传热温差随时间的变化情况。试验结果表明,均温板传热温差在低转速下(7.5 r/min)与静止状态下变化不明显,传热温差随着转速增加而逐渐增大。停止旋转后,传热温差快速下降。在高转速(30 r/min和45 r/min)下,传热温差增加值最大约10℃,最小约4℃。In order to analyze the variation of the heat transfer performance of powder sintered aluminum vapor chamber under rotational centrifugal force, a rotation test platform is built in this paper to simulate different conditions of different rotation speeds and test the heat transfer temperature differences of the vapor chamber under stationary state, low-speed rotation state and high-speed rotation state. The variation of heat transfer temperature difference of the vapor chamber with time is studied and recorded when the rotation speed changes. The experiment shows that the heat transfer temperature difference does not change significantly under low-speed rotation(7.5 r/min) state and stationary state, but will increase as the rotation speed increases.After the rotation stops, the heat transfer temperature difference decreases rapidly. At high rotation speeds(30 r/min and 45 r/min), the increment of the heat transfer temperature difference is about 10℃ at most and about 4℃ at least.
