VACUUM THERMAL PERFORMANCE TEST DEVICE FOR TWO-PHASE FLUID LOOP, AND METHOD

摘要

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.
