Halogen lamp complex gradient thermal fatigue test device for test piece liquid cooling isolation layer

Abstract

The invention discloses a halogen lamp complex gradient thermal fatigue test device for a test piece liquid cooling isolation layer. The halogen lamp complex gradient thermal fatigue test device comprises a metal plate outer cover box body (1) with a hexagonal section, a box body upper cover (2) arranged at the top of the metal plate outer cover box body (1), a quartz lamp holder (3) arranged in the metal plate outer cover box body (1), a plurality of quartz lamp tubes (4), and a test piece quartz isolation hood (5) arranged on the quartz lamp holder (3). According to the invention, high-temperature-gradient heating can be carried out on a small-area sample to be measured, and salt mist and water mist cooling treatment can be carried out on the small-area sample; the quartz protective cover also has the effects of protecting the quartz glass lamp tube and prolonging the service life of the quartz glass lamp tube; and the gradient thermal shock test device is economical, safe, clean, quiet, flexible and efficient.

Description

technical field [0001] The invention relates to a complex gradient thermal fatigue heating device for a test piece liquid cooling isolation layer halogen lamp, which is suitable for thermal fatigue heating experiments of small-area complex curved surface structures, and can be used in extreme thermal environments such as aeroengine blades, small high-temperature thermal structural parts or thin flow Simulation of high temperature tests in the environment. Background technique [0002] Aeroengines are the "Pearl in the Crown of Modern Industry" and an important symbol to measure a country's comprehensive scientific and technological level, basic strength of science and technology industry and comprehensive national strength. With the improvement of the performance of aero-vehicles, the thrust-to-weight ratio required by aero-engines also has higher requirements. With the improvement of aero-engine performance, the gas temperature at the air inlet of the high-pressure turbine...

AI Technical Summary

Problems solved by technology

[0004] 1. The exposed quartz lamp heating tube, the back radiation of the lamp tube cannot be efficiently used in the heating process

[0005] 2. Single customized equipment does not have the adaptability to aerodynamic heating tests of different types and sizes of curved surfaces

[0006] 3. The temperature field distribution of aeroengine blades is complex, the temperature gradient is large, and the area of ​​the blades is small. For customized equipment, it is difficult to write the control system and the experiment period is long

[0007] 4. When cooling the test piece, the cooling liquid may splash on the quartz lamp tube, resulting in a large thermal stress on the surface of the quartz lamp tube and damage it

[0008] 5. It is impossible to simulate the high-altitude thin flow environment or even the vacuum environment, and it is also impossible to use protective gas to conduct experiments
