PURPOSE: A heat exchanger using a nano-silver pin having antibiotic and hydrophilic properties is provided to maintain antibiotic properties for a long time by forming a hydrophilic coating layer. CONSTITUTION: A heat exchanger using a nano-silver pin having antibiotic and hydrophilic properties comprises multiple aluminum pins. The aluminum pin is formed by forming corrosion-resisting coating layers(22) on an aluminum pin member(21) and forming hydrophilic coating layers(23) on the corrosion-resisting coating layers. The hydrophilic coating layer is formed using a hydrophilic coating solution having nano-silver.
