Embodiment

[0022] See attached figure 1 , when testing some special products of the aerospace system, the test product 1 is fixed by the tooling 2, and the tooling 2 can be different according to the shape of the test product 1, and the infrared lamp array 3 is set outside the test product 1, and the infrared lamp The array 3 is arranged according to the shape of the test product 1, so that it is evenly arranged outside the surface of the test product. The infrared lamp array 3 is fixed by the upper support set on the tooling 2. The surface of the test product 1 was uniformly heated. The number and distribution density of infrared lamps in the infrared lamp array 3 are set according to the heating demand of the test product 1, which can provide more than 1500W / m 2 Heat flux density, up to 1700W / m 2 .

[0023] Continue to see attached figure 1 , the shape of the tooling 2 is set to surround the test product 1, and the infrared light array 3 is set between the tooling 2 and the test pr...

Abstract

The invention relates to an infrared lamp array heating system in the infrared lamp array heating application technical field. The infrared lamp array heating system comprises a test product and a tool, wherein the test product is fixed by the tool; an infrared lamp array is arranged out ofoutside the test product; one side of the infrared lamp array, which is back on the test product, is provided with a thermal-insulation lampshade; and the reflection layer of the thermal-insulation lampshade is used for transferring diffusion heat to the test product. According to the equipment disclosed by the invention, the problem of overlong temperature rise and reduction of a vacuum thermal test of a spacecraft assembly is solved, a product with a low absorptivity can effectively obtain an anticipative heating rate, and the pollution problem caused when the a spacecraft is heated with a traditional method is solved. Meanwhile, the thermal-insulation lampshade is arranged between the infrared lamp and the a frame to avoid thermal deformation due to the fact that the frame is heated, and the test precision is improved. Further, the test reliability is improved, and the test cost is greatly lowered.

Description

technical field [0001] The invention relates to the technical field of infrared lamp heating applications, in particular to an infrared lamp array heating system. Background technique [0002] Before the spacecraft is launched into space, it must conduct a vacuum thermal test simulating a cold and dark space environment in a special space environment simulator to test the rationality of its thermal design and assess the high and low temperature performance of its stand-alone. [0003] For some special products of aerospace systems, they are heated by solar radiation, earth infrared radiation, and solar radiation reflected by the earth in low-earth orbit, and at the same time, they are also heated by internal components of the product, which will cause the temperature of the product to rise to a higher temperature. When the product enters the shadow of the earth, due to the cold black background of 2-4K in the universe, under extreme working conditions, the internal heat sour...
