Problems solved by technology

[0003] With the progress of the technical level, due to serious aerodynamic heating, the supersonic and hypersonic models use heat insulation materials on a large scale on the projectile body, and the product sealing is relatively good. During the heating and cooling process of the comprehensive environmental stress test, the external The heat conduction rate in the cabin is slow, which leads to a long time for the temperature balance of the equipment in the cabin, which makes the entire comprehensive stress test take a long time, with low efficiency and increased cost

Abstract

The invention relates to a forced convection heat transfer test device for a comprehensive environmental stress test. The forced convection heat transfer test device for the comprehensive stress testprovided by the invention comprises a test box, an air supply system, an air supply pipeline and a ventilation cover; the air supply system is arranged on the top of the test box; the ventilation cover is installed on the opening of the cabin of a tested product; the ventilation cover is connected with the air supply system through the air supply pipeline; the air supply system feeds an airflow, the temperature and the humidity of which are same as that in the test box, into the cabin of the tested product; the temperature equilibrium time in a test process is accelerated; the test time is shortened; the test efficiency is increased; and the cost is reduced.

Description

technical field [0001] The invention relates to the field of comprehensive environmental stress tests, in particular to a forced convection heat transfer test device for comprehensive environmental stress tests. Background technique [0002] The comprehensive environmental stress test is a test for quality assessment of the product and its internal equipment, and plays a key role in the process of product development and production. The test simulates the real environment of the product task profile by applying temperature, humidity, and vibration stress, and exposes the faults of the product in a short period of time, and makes improvements to improve the quality and reliability of the product. [0003] With the progress of the technical level, due to serious aerodynamic heating, the supersonic and hypersonic models use heat insulation materials on a large scale on the projectile body, and the product sealing is relatively good. During the heating and cooling process of the...
