Oil Coolers

A reliable source for Oil Coolers information and leading Oil Coolers Companies & Manufacturers.

An oil cooler is a mechanical device that removes surplus heat energy from an internal combustion engine through a heat exchanger. This component is utilized for cooling many mechanical parts using oil. These parts include the transmission system, engine, and more. Read More…

Oil Coolers Oil coolers are tube heat exchangers that are specifically designed for the transfer of heat, or thermal energy, from heated oil by carrying the oil through cooling units in order to cool it, or using the oil to absorb heat. It can be used to cool items 100°C or higher; unlike water, which has a much lower boiling point. Particularly useful for automotive or mechanical applications, oil is an electrical insulator that is used inside of or in direct contact with electrical components.

Heat Exchangers

Heat Exchangers

Heat exchangers are pieces of equipment used to transfer heat between two or more fluids. This process usually involves abundant working or utility media such as water or air that rejects or absorbs heat from a more valuable fluid such as crude oil, petrochemical feedstocks, and fluidized products...

Shell and Tube Heat Exchangers

Shell and Tube Heat Exchangers

A shell and tube heat exchanger (STHE) is a type of heat exchanging device constructed using a large cylindrical enclosure, or shell, that has bundles of perfectly spaced tubing compacted in its interior. Heat exchanging is the transfer of heat from one substance or medium to a similar substance or medium...

Plate Heat Exchanger

Plate Heat Exchanger

A plate heat exchanger (PHE) is a compact type of heat exchanger that utilizes a series of thin metal plates to transfer heat from one fluid to the other. These fluids are typically at different temperatures...

What is an Oil Cooler?

Oil coolers are small radiators found in front of water-based radiator systems. Their primary purpose is to reduce the temperature of the vehicles while running; thus, the device works only while the vehicle is running.

Oil Cooler

The cooled oil adds a lot of purpose to the high-stress transmission oil—engines with cooling fans quickly cool oil and water-based radiators, which is why they offer additional advantages.

Because an oil cooler functions as an additional cooling component, its application to air cooled engines will intensely reduce high temperatures. Therefore, the lifespan of the engine will be significantly increased. Heavier vehicles make good use of oil coolers, which help put more stress on the drive train.

Efficient cooling keeps hot engine oil operating at cool temperatures and decreases the chance of untimely breakdown.

Types of Oil Coolers

Engine oil coolers can be generally categorized into two types like oil to water and oil to air.

Oil to Water Coolers

Oil to Water Cooler

In oil to water coolers, the coolants pass through heat exchanger elements of some parts. Then, the coolant is activated by either adding heat energy to cold oil or taking heat energy from excess hot oil.

Oil to Air Coolers

These coolers are small radiators that activate the engine oil to cool directly with ambient air from the cooling fans. Most oil to air coolers operate using a thermostatic bypass valve, which stops engine oil from flowing through the cooler before reaching its required operating temperature.

Oil to Air Cooler

Types of engine coolers include basic tube and fin style, where oil flows through one or multiple coolers. Other types might have many cooling rows or a stacked plate type. Finally, some oil coolers are header style, where end tanks are constructed like radiators.

Working Principle of Oil Coolers

Oil to air coolers are generally mounted in the radiator’s front, though they have the same shape. This gives engine oil fast access to cold fresh air from the cooling fan. In many cases, oil flows from the engine as a “sandwich” adapter.

This adapter is placed between the engine block and an oil filter since it permits hot oil to pass through the filter. It then flows through the cooler before flowing back to the engine as a recurring process. Other sandwich adaptors are made with thermostatic bypass, which disables oil from flowing until it reaches a certain temperature.

An inline thermostat provides the same bypass operation. In vehicles without space for mounting at the radiator’s front, manufacturers offer coolers in other places in the engine.

Advantages of Oil Coolers

Below are the advantages of oil coolers in internal combustion engines:

  • With a thermostat, an oil cooler cools down heated oil to an exact temperature.
  • It ensures appropriate cooling of oil before passing it.
  • The oil temperature is controlled in the oil to water cooler.
  • Installation of an oil cooler is quite easy.
  • Oil cooler improves the operation of an engine.
  • It reduces the usage of a water cooling system which can corrode the engine.
  • As oil significantly works as a coolant, additional coolant cylinders, radiators, and pumps are excluded from the engine design.
  • Oil circulation is effective and controlled.

Disadvantages of Oil Coolers

Despite the advantages of oil coolers, some drawbacks still occur. Below are the drawbacks of the engine part:

  • Oil can be flammable.
  • Extra oil is needed to operate an oil cooler.
  • Extra maintenance is required.
  • Thermostat failure stops oil circulation, specifically if permanently locked.
  • Over-cooling can happen if a valve stays open.

Oil Cooling Applications

Modern vehicles feature high-performance engines with hydraulic and transmission systems which utilize oil for cooling, cleaning, and lubrication purposes. The heat produced from these systems must be cooled for optimal functioning. Oil passing through these systems absorbs the heat and exchanges it with the ambient air. As the systems work under high pressure, an oil cooler must be robust for high working pressure.
