    • Provided are a vacuum thermal performance test device for a two-phase fluid loop, and a test method, for testing and evaluating the heat transfer capability and the blocking performance of a two-phase fluid loop at different operating temperatures. The test device comprises a heat dissipation plate (11), a temperature control heater, a multi-layer heat insulation assembly, a temperature sensor, a simulation heat source (15) and a loop support (17). The operating temperature of a two-phase fluid loop is altered by controlling the temperature of an evaporator (1) and the temperature of the heat dissipation plate (11). The test method tests the heat transfer and blocking capabilities of the vacuum thermal performance of a gravity-driven two-phase fluid loop. The arrangement of the temperature sensor is beneficial for the observation of the state of an ammonia working medium within the two-phase fluid loop, each component within the two-phase fluid loop is examined as to whether a temperature requirement is satisfied, and the two-phase fluid loop is also examined as to whether balance is achieved.
    • 提供了用于两相流体回路的真空热性能测试装置以及用于测试和评估在不同操作温度下的两相流体回路的传热能力和阻塞性能的测试方法。 该测试装置包括散热板(11),温度控制加热器,多层隔热组件,温度传感器,模拟热源(15)和环形支撑件(17)。 通过控制蒸发器(1)的温度和散热板(11)的温度来改变两相流体回路的工作温度。 该测试方法测试重力驱动两相流体回路的真空热性能的传热和阻塞能力。 温度传感器的设置有利于观察两相流体回路内的氨工作介质的状态,检查两相流体回路内的每个部件是否满足温度要求,并且两个流体回路 还检查了相流体回路是否达到平衡。
