Abstract

The invention provides a performance testing apparatus and method for a flat-plate LHP capillary core. An evaporator of the apparatus comprises an evaporator main shell, an evaporator cover plate, a main sealing ring, a secondary sealing ring, a to-be-tested capillary core and a fastener. The method comprises the following steps: bonding of a heater with a measuring point; testing of heat transfer capability; and testing of inverse gravity capability. The performance testing apparatus provided by the invention can simulate an ideal combination state and maximally reduce influence of other non-relevant factors on result, is repeatedly usable, and adaptive to to-be-tested capillary cores of different sizes by changing the sizes of the main and secondary sealing rings, so test cost is decreased.

Description

technical field [0001] The invention relates to a performance testing device, in particular to a performance testing device and method of a flat-plate LHP capillary core, in particular to a flat-plate LHP capillary core performance testing device and method for a satellite. Background technique [0002] LHP is an ideal heat transfer element. It has the characteristics of strong heat transfer capacity, high heat flux resistance, reversible gravity operation, and flexible arrangement. It has important applications in the field of aerospace thermal control. Capillary core performance is the core component related to LHP, and its performance plays a decisive role in the performance of LHP. At present, most of the test methods for capillary core performance use to observe its water absorption speed, but this method cannot directly reflect the performance of capillary core. The test results Easily affected by many factors such as air. [0003] The flat-plate LHP capillary perform...
