Quartz lamp radiant heating equipment and reflectors

Abstract

The present application discloses a quartz lamp radiation heating device and a reflector suitable for use in a low pressure environment. An electrode cover (3) is designed for insulating and protecting the electrode (1). A set of insulating ring assemblies is designed to insulate and protect the exposed live parts, reduce the area of ​​the live exposed parts of the heating surface of the quartz lamp (2), and solve the problem of arc discharge in a low pressure environment. A novel reflector (19) structure is provided, which can meet the requirements of strength, rigidity, pressure resistance and sealing performance in a low-pressure environment. The first conduit (9) and the second conduit (12) with end face sealing are also proposed, which greatly enhances the sealing performance at the joint of the water pipe and can well meet the needs of use in a low-pressure environment. The invention promotes the development of the low-pressure environment thermal test technology in the aerospace field, has wide application prospects, and has good military and economic benefits.

Description

technical field [0001] This application relates to the field of thermal testing of aerospace structures, in particular to a quartz lamp radiation heating device and a reflector. Background technique [0002] The aircraft has the problem of aerodynamic heat generation during high-speed flight, and it is necessary to conduct simulated heating tests on the ground to evaluate the performance of its structure such as heat insulation, heat resistance, and thermal matching. In recent years, the demand for aircraft structural thermal tests in low-pressure environments has become increasingly prominent. The test objects and heating equipment are placed in a closed, low-pressure space for testing to simulate the low-pressure or vacuum thermal environment after the aircraft flies out of the atmosphere. [0003] Quartz lamp radiation heating equipment is a commonly used heating equipment in the field of ground thermal testing. Compared with the normal pressure open environment, the low...
