Natural air cooling

A cooling method that does not use external power sources such as a fan to dissipate heat generated by electrical and electronic devices to the outside. Heat is released through natural air convection, radiation, or thermal conduction. To enhance natural cooling, a heatsink specifically designed for passive cooling can be installed to increase the surface area for cooling or to facilitate convection. If heat dissipation is insufficient with natural cooling, forced cooling using devices such as a fan is applied.
