Hydraulic Oil Cooler

High-Quality Oil Cooler for Optimum Performance

Off-road machinery owners know that keeping their engines and hydraulic oil running at their optimum temperature is an important factor for optimum performance. However, inevitably, the engine and hydraulic oil will exceed the optimum temperature, which can affect performance. To solve this problem, it is time to install a high-quality oil cooler for your construction or agriculture machine.

FridayParts offers a wide range of quality engine oil coolers and hydraulic oil coolers to fit your excavators, loaders, dozers, generators, and more, whether a nice Bobcat 763 hydraulic oil cooler or other nice items, they are popular among overseas customers. Our high-quality products will help maintain the correct temperature for your engine and hydraulic systems and also help limit damage to them.

What Is An Oil Cooler?

The oil cooler is an oil cooling equipment commonly used in hydraulic system and lubrication systems. It can exchange between two fluid media with a certain temperature difference, and ensure the normal operation of the system by keeping oil temperature low.

Engine oil coolers

Engine oil coolers are designed to keep the temperature of the engine oil correctly by cooling the engine oil, so that can ensure efficient engine operation and extend engine life.

Hydraulic oil coolers

They also named heat exchangers, are designed for cooling hydraulic oil in hydraulic systems. Also, it needs to ensure that the viscosity of hydraulic oil is reasonable to avoid damage to hydraulic components and maintain the hydraulic system operating efficiently.

Both of them are types of heat exchangers, with different designs and performances, and they complement each other. However, compared with engine oil coolers, hydraulic ones are larger in size and have better cooling ability.

Tips to Size Hydraulic Oil Cooler

• Flow

The higher the flow rate of the hydraulic oil flow through the cooler, the more heat the cooler needs to dissipate.

• Continuous input power of the system

Taking kilowatts as the working unit, assuming that the continuous input power is 80kW, the efficiency is 70%. The output power is then 56kW to do useful work and 24kW to be converted to heat. It means that the oil cooler has to dissipate 24kw of heat in order to maintain the ideal oil temperature.

• Specific heat capacity

Determine the specific heat capacity of your hydraulic fluid, different hydraulic fluids have different specific heat capacities.

• Heat load

Calculation method

Q = m x c x (T2 - T1)

In the formula, Q represents the heat load (kW); m represents the mass flow rate of hydraulic oil (kg/s); c represents the specific heat capacity of hydraulic oil J/(kg °C); T2 represents the temperature of hydraulic oil entering the cooler (°C); T1 represents the temperature (°C) of the hydraulic oil coming out of the cooler.

Assuming that you have obtained relevant data information, and substituting the above formula, the thermal load of the hydraulic system can be easily calculated. However, if you want to calculate a more accurate heat load, you need to consider more factors such as oil temperature, ambient temperature, etc.

• The heat transfer capacity of the cooler (cooling capacity)

It's one of the key factors in deciding the size of hydraulic oil coolers.
The heat transfer capacity of the cooler refers to the heat that can be dissipated per unit of time. The cooling capacity of a cooler is determined by its design and can be found in its specifications.

Finally, for reliability, you'd better buy a large one instead of a small one, and the specification can be increased to 20% of the calculated value.

Some Notable Bad Signs

Similarly, when bad signs happen, generally it has the following signs:

• Overheating
• Dirty oil
• Oil leak
• The slower operation and lower efficiency
• Corrosion in the hydraulic system
• Increased noise in the hydraulic system

There are many ways to check when the above warnings happen. In case of oil leakage or other situations, you'd better buy a new one from your reliable engine parts supplier.
