Best 5 Picks For Transmission Oil Cooler

Transmission Oil Cooler

When you run your car on the road it produces so much heat that it needs a specific cooling system to cool it down continuously to avoid any damage. If your engine does not run smoothly due to overheating you will not get the optimum performance from your motor vehicle. So it is important to know the cooling systems before you can decide which one you want to buy. There are mainly two types of cooling systems available based on the cooling method employed.

  • Engine Oil Cooler System: This system is also known as the transmission oil cooler. It uses engine oil as a coolant for cooling down the automobile’s internal combustion engine such as the crankshaft, connecting rod, pistons, bearings, etc.
  • Radiator Cooling System: Through this system, the heat around the combustion chamber, cylinders, and other internal manifolds are removed.

Engine oil cooling system also helps to maintain the lubrication of various engine parts. Nevertheless, when the temperature goes up to 220°F, the radiator coolant comes into play yet the oil cooling still serves its secondary purpose which is lubrication.

Types of Engine Oil Coolers

The engine oil coolers are arranged into two basic types described below.

Tube and Fin style Engine Oil Coolers

The Tube and Fin style oil coolers are arranged in a way that the oil has to circulate them through the cooler lines. Once the oil is released, the heat is taken up by the tubes and then gets released to the fins as they are located externally to be exposed to air that blows around and consumes the engine heat.

You will see in the other ordinary coolers that the oil is touching the walls of the tube that fastens the cooling process but also formulates an insulation layer. This insulation layer creates obstacles for the remaining oil that is not in contact with the tube’s walls. As a result, the cooling is not uniform and it remains at a high temperature which badly affects the efficiency of the system.

Although to increase the efficiency of the system some modifications are done like fitting the agitator in the tube that helps to prevent any insulation to form, as a result, the oil flow improves thus improving the efficiency.

Stacked-plate Engine Oil Coolers

The Stacked-plate engine cooling system is not considered as effective as the Tube-Fin types coolers that we just mentioned. In this system, a stack form is created with the plates so that the placed oil can undergo it thus removing the heat from the machine as the air voids these plates. The air moves slowly bit by bit making the process slow and comparatively inefficient.

But again to improve the efficiency some modifications are applied to the engine cooling systems that include:

  • Expanding the surface area of the tubes and lines like the Tube-Fin style coolers.
  • Using lightweight materials like aluminum
  • Trying different designs for oil coolers.

You can find various engine oil coolers available in the market. But before getting into any further discussion we would be happily informing you that we have eased up things for you. We, Best Oil Cooler team, would like to introduce you with our 5 best picks for transmission/engine oil cooler.
