摘要
均热板的主要性能参数包括均温性和传热功率,这两大参数指标直接反映均热板性能的优劣。基于实际均热板测试需要,设计了一种均热板测试系统,具有携带方便、自动化程度高等特点。测试系统主要由加热与冷却模块、控制模块、数据采集与分析模块三大部分组成,合理地运用了浮动支撑、滑动副、球关节浮动接头等机械结构减小了测试过程中可能出现的误差,运用Lab VIEW设计的数据采集分析系统确保了测试精度和可靠性,并运用了传热与传质基本原理分析计算了系统板翅热沉的热阻,其值为0.0871(℃/W),为进一步理论分析提供了依据。
The main parameters of the vapor chamber are the average temperature and the power of heat transfer, those two are directly response to the vapor chamber performance whither good or bad. Based on the vapor chamber actual test requires, the design of the vapor chamber test system is portable and with a high degree of antomatior~ The test system consists of heating and cooling module, control module, data acquisition and analysis module. The floating support, the sliding friction pairs, the floating ball joints and other structures are rational designed to reduce the errors that may occur during the test. And use the LabVIEW to design a data acquisition and analysis system to ensure the accuracy and reliability of the test device. Apply the.fundamentals of heat and mass transfer to analysis and calculation the thermal resistance of the system plate fin sink, the value is 0.0871 （ ℃/W ） , and to lay the foundation for further theoretical analysis.
