Embodiment Construction

[0032] If certain words are used to refer to specific components in the specification and claims, those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect. The subsequent description of the specification is a preferred implementation mode for implementing the application, but the description is for the purpose of illustrating the general principle of the application, and is not intended to limit th...

Abstract

The invention discloses a temperature, pressure and air supply comprehensive testing device and method for aircraft electronic equipment. The device comprises: a box body, test space partition plates,a convection heat transfer system, a radiation heat transfer system, a vacuum system, an air supply system and a centralized control system, wherein the convection heat transfer system and the radiation heat transfer system cooperatively work to obtain the temperature required for the test; and when the pressure in the test space is low and the convection heat transfer system cannot exchange heatwell, the radiation heat transfer system can play the role of obtaining the required temperature. The device disclosed by the invention has the advantages that the realization is simple, the temperature of radiant panels can be rapidly changed and the temperature and the pressure can be simultaneously rapidly changed by cooperating with the convection heat transfer system and the vacuum system; and the sub-systems cooperatively work to ensure that the comprehensive testing requirements of temperature / pressure / air supply can be met and especially, the requirements for temperature changing andstabilizing can be met.

Description

technical field [0001] The invention relates to a temperature and pressure air supply comprehensive experiment device and method for aircraft electronic equipment. Background technique [0002] Whether the electronic equipment equipped on the aircraft can continue to work stably is directly related to the performance and reliability of the aircraft. For this reason, during the design, identification and acceptance process of aircraft electronic equipment, it is necessary to conduct a comprehensive inspection of these electronic equipment in the ground laboratory. The aircraft is equipped with an environmental control system. One of its main functions is to send air at a normal temperature of 15 to 35°C into the electronic equipment compartment to improve the stability of the electronic equipment. The functional block that simulates the function of the environmental control system in the experimental device is called product air supply, which is realized by the air supply sy...
