A device used to control an electric cooling fan based on engine temperature or air conditioning system demand. It consists of a relay, wiring, and necessary connectors, enabling the fan to be switched on and off automatically. For example, this assembly can be employed in automotive applications to prevent the cooling fan from running continuously, thereby reducing electrical load and increasing fuel efficiency.
Implementing such a system offers several advantages, including improved engine cooling management, reduced strain on the vehicle’s electrical system, and potentially prolonged fan motor life. Historically, manually controlled cooling fans were common, leading to inefficiencies and potential overheating issues. This automated approach provides a more reliable and efficient method for managing engine temperature.
