| Abstract: | In order to meet the demand for wide range external heat flow simulations in the vacuum thermal test, a “random form” filament heating device is designed and developed in this paper. With armored heating wires, the device can be processed according to different shapes and surface states of products for simulating heat flux from 20 W/m2 to 1500 W/m2 technically. The experimental results under vacuum cryogenic conditions show that the filament heating device can provide heat flow with a temperature control accuracy within ±0.35 ℃, a temperature stability within ±0.7 ℃, and a heat flux non-uniformity of better than 2.5%. |
