What Are Coolant Temperature Control Devices?

Coolant Temperature Control Devices are components in both automotive and industrial applications that regulate the temperature of engines by managing coolant flow. They include thermostats, radiator fans, and electronic control units (ECUs) that maintain the required operating temperature.

Types of Coolant Temperature Control Devices

1. Thermostats

   • Function: Opens and closes to control coolant flow based on engine temperature.
   • Application: Typically found in cars to allow the engine to reach its optimal operating temperature before allowing excess coolant into the radiator.

2. Cooling Fans

   • Function: Expels heat from the radiator.
   • Application: Commonly used in both automotive and industrial settings to provide airflow over the radiator when the vehicle is not moving.

3. Electronic Control Units (ECUs)
