Cooling radiator with automatic transmission cooling
The automatic transmission cooling radiator consists of two main components:
1. Engine radiator
* This is the main radiator of the vehicle that cools the engine coolant.
* It consists of a series of metal tubes passing through several rows of thin plates.
* Coolant circulates through the tubes and air passes over the fins, removing heat.
2. Automatic transmission heat exchanger
* This is a small radiator located inside the engine radiator.
* It consists of many small channels through which automatic transmission fluid circulates.
* Engine coolant flows around the passages to cool the automatic transmission fluid.
Operating principle
When the engine is running, coolant circulates through the engine radiator, where cool air removes heat from it. The cooled coolant then passes through the automatic transmission heat exchanger, where it cools the automatic transmission fluid, removing heat from the automatic transmission itself.
Peculiarities
* The heat exchanger is usually built into the top of the engine radiator. This allows you to use heat from the engine to warm up the automatic transmission fluid in cold weather.
* Some radiators have separate automatic transmission cooling pipes. This provides more efficient cooling for automatic transmissions operating under high loads.
* Automatic transmission cooler radiators are often larger and heavier than conventional radiators. This is due to the need to dissipate more heat.
Advantages
* Improved automatic transmission cooling, which extends its service life.
* More stable automatic transmission temperature, which ensures smooth gear shifting and protection against overheating.
* Higher performance of automatic transmission fluid, which leads to improved performance and fuel efficiency.
