The cooling radiator with an automatic transmission (automatic transmission) works as follows:
1. Transmission fluid circulation:
* The automatic transmission continuously pumps transmission fluid through the radiator.
* Transmission fluid absorbs the heat generated by the automatic transmission during operation.
2. Heat transfer:
* The radiator consists of thin metal tubes or channels that are surrounded by cooling fins.
* As transmission fluid passes through the tubes, it comes into contact with the surface of the cooling fins.
* Heat from the transmission fluid is transferred through the surface of the fins to the outside air or engine coolant.
3. Coolant cooling:
*In some systems, the automatic transmission cooler is also used to cool the engine coolant.
* Engine coolant passes through a separate section of the radiator, where it also dissipates heat to the outside air.
4. Airflow:
* Air flow over the radiator helps remove heat from the fins.
* Air can circulate through the radiator passively (natural flow) or actively (using a fan).
5. Temperature adjustment:
* The thermostat located in the automatic transmission regulates the flow of transmission fluid through the radiator.
*When the transmission fluid reaches a certain temperature, the thermostat opens, allowing more fluid to circulate through the radiator for cooling.
Thus, the automatic transmission cooler helps maintain optimal operating temperatures for both the transmission fluid and the engine coolant.
