Abstract

This study handled a heater fabricated by silver screen printing for satellite applications. In the space environment, heat is transferred only by conduction and radiation. The designed heater for typical use is 152.4mm in width and 25.4mm in length, and the thickness does not exceed 2mm. It was manufactured according to the ESCC (European space components coordination) standard. When the experiment is conducted at room temperature, convection occurs on the surface, and thermal contact resistance occurs when the heater and CFRP (carbon fiber reinforced plastic) are bonded. A temperature measurement experiment was conducted for the heater, and the convective heat transfer coefficient and thermal contact resistance were found by comparing with the simulation value. Based on this simulation method, vacuum analysis is performed by applying a heater attached to CFRP. A performance curve of the heater was prepared, which enables the calculation of the power according to the operating environment temperature of the heater.
