Method of manufacturing heating/cooling coil with nanometer silver coating layer

Abstract

Disclosed herein is a method of manufacturing a heating/cooling coil with a nanometer silver coating layer, in which vacuum deposition of nanometer silver is performed on the surface of a heating/cooling coil, thus preventing corrosion of aluminum, sterilizing heating/cooling gas and fluid, and maintaining high heat conductivity. The method includes feeding argon gas into a vacuum chamber at a pressure of 10−5-10−7 torr until the pressure in the vacuum chamber reaches 1002 torr, applying high negative voltage (−500˜−5000 V) to nanometer silver particles serving as a target material so that cations of argon gas induced by glow discharge collide with the surface of the nanometer silver particles electrically charged to a cathode, to eject the nanometer silver particles in the form of atoms in vapor phase, and forming the nanometer silver particles in vapor phase into a nanometer silver coating layer on the surface of the heating/cooling coil. In the current invention, ion sputtering is used to coat the surface of the heating/cooling coil with nanometer silver, thereby effectively increasing corrosion resistance for a long time and further enhancing surface sterilization effects.
