PRODUCT DETAIL
High-Brightness 80W LED Spotlight (Clover-Leaf Design) – Suitable for Motorcycles, EVs, Trucks, and Off-Road Use
NOTE :
This light cannot be turned on while stationary; it requires airflow for cooling.
# Ram-Air Cooling
Simply put: **Ram-air cooling** refers to the process of utilizing the oncoming airflow generated while the vehicle is in motion to blow directly onto the radiator and dissipate heat; it is the fundamental form of air cooling.
## Principle
As the vehicle moves forward, the relative airflow rushes in through the front air intake and **strikes the radiator** (whether it is a coolant radiator, intercooler, or oil cooler) directly; the air passes through the cooling fins, carrying the heat away.
The higher the vehicle speed, the greater the velocity of the oncoming air, and the more effective the ram-air cooling becomes. Conversely, when the vehicle is stationary and idling, there is virtually no ram-air, so an electric fan is required to provide the necessary airflow.
>
> Ram-air = Natural oncoming airflow generated by vehicle movement; **it is not air blown by a fan**.
