Forced air cooling

As a heat countermeasure for electrical and electronic equipment, when natural cooling such as convection is insufficient, heat is forcibly expelled using a blower such as a fan. Many devices that generate a large amount of heat and are installed inside enclosures adopt a forced cooling method. There are methods in which the fan operates continuously regardless of temperature, and methods in which a heat sensor or similar device is used to operate the fan when a specified temperature is exceeded.
