摘要
The present invention is an apparatus for preventing corrosion of a cooling water channel of a blower (B) that supplies gaseous nitrogen at a predetermined temperature into a thermal vacuum chamber providing a space environment for a thermal vacuum test of an artificial satellite, and cooling water to the cooling water channel of the blower Cooling water supply pipe 10 for supplying; A cooling water discharge pipe 20 that discharges cooling water from the blower; A first opening / closing valve (15) for opening and closing the cooling water supply pipe; A second opening / closing valve (25) for opening and closing the cooling water discharge pipe; A gas supply pipe 30 having one end connected to the cooling water supply pipe 10 between the first opening / closing valve 15 and the blower to supply gas to the blower; And a third opening / closing valve (35) that opens and closes the gas supply pipe, and provides a corrosion protection device for a cooling water channel of a blower for a thermal vacuum chamber.
