What is a Hydraulic Oil Cooler?

Just like the human body, if the hydraulic system is considered the body, then hydraulic oil is considered the blood source. Hydraulic oil circulates throughout the system, supplying control and actuator parts. Oil used for hydraulic systems has many types such as: 32, 46, or 68…

A hydraulic oil cooler, also known as a hydraulic oil heat exchanger, is a hydraulic device used to cool or lower the temperature of the entire hydraulic system during operation. Hydraulic oil coolers usually come in two forms: water-cooled hydraulic oil coolers and air-cooled (fan) hydraulic oil coolers.

When hydraulic systems or devices work for long periods and frequently, the temperature of the entire system will be very high. This affects the system quality, creating oil boiling, oil thinning, and oxidation phenomena, making parts like pistons and cylinders easily damaged and quickly wearing out the hydraulic system.

At this time, the hydraulic oil cooler (oil heat exchanger) will have the effect of lowering the system temperature, helping to stabilize the temperature, cooling the oil, balancing device operation, minimizing the possibility of fire and explosion, and extending the lifespan of the entire hydraulic system.

Hydraulic oil radiators are very suitable for installation with devices including hydraulic pumps, hydraulic power units, electrical regulators, hydraulic cylinders, hydraulic pumps and many other hydraulic systems, …

Normally, hydraulic oil will work stably at a temperature of 45°C – 65°C. If it exceeds this range, the hydraulic oil cooler (oil heat exchanger) will help stabilize and lower the temperature to the lowest working level.

Hydraulic oil coolers (oil heat exchangers) come in a variety of types imported by the company officially from many countries like China, Taiwan, South Korea, Japan, and Europe with the most competitive quality and prices in the current market.

Operating Mechanism of Hydraulic Oil Radiators

The hydraulic oil cooler has a simple operating principle: supplying power to the power unit makes the motor move, which in turn moves cooling parts like fan blades or the radiator, lowering the hydraulic system to the most suitable temperature. Air pushes the oil to heat through a component similar to a fan to reduce the temperature and uses surrounding air to cool the lubricating oil, without needing access to the electrical circuit.

For air oil coolers, there is a fan blade that sucks air on the side of the power line or motor. Therefore, no additional power source is needed for the oil radiator to operate. With optimal cooling capability, the oil cooler allows the electric motor to eliminate all excess heat and power loss that affects the machine’s operating efficiency. According to statistics, oil coolers can be used in many different production fields such as:

• Oil cooling for air compressor systems: Atlas Copco, Ingersoll Rand, Kobelco, etc.
• Oil heat dissipation for hydraulic pumps of various 500kg to 10-ton cargo lifts.
• Gasoline engines
• Reducing heat for furnaces
• Reducing heat for machinery, equipment, and the surrounding environment of the machine system

Structure of Hydraulic Oil Radiators

An air-cooled hydraulic oil cooler consists of parts such as:

• External housing of the hydraulic oil cooler
• Cooling fan blades
• Electric motor

A water-cooled hydraulic oil radiator structure:

• Hydraulic oil cooler cap
• Hydraulic oil cooler body
• Sealing gasket
• Shell and tube heat exchanger

Effects of Hydraulic Oil Radiators

Oil radiator or hydraulic oil heat exchanger, oil cooler, oil cooling unit, … is a device used with the function of lowering and stabilizing oil pressure to the allowed limit. Below are some main effects of hydraulic oil radiators:

• Oil cooling: The radiator helps regulate the temperature of hydraulic oil by reducing heat from the oil and exchanging heat with air or water. Thanks to this, the machine system will maintain the temperature within a safe range, avoiding overheated oil which can cause problems such as damage, loss of work capacity, and wear.
• Increased efficiency: Hydraulic oil at a stable temperature helps the system operate steadily and with higher efficiency. When the temperature rises, hydraulic oil can lose viscosity, causing pressure loss and system inefficiency.
• Protection of machine system components: Excessive heat can harm components in the hydraulic system, weakening the structure and increasing the risk of failure. The radiator helps protect these components from excessive temperatures.
• Increased lifespan of machine systems: Maintaining a stable temperature helps increase the lifespan of the hydraulic oil, the system, and internal components, including the hydraulic power unit. Stable temperature helps avoid weakening and failure due to deformation and loss of work capacity of components.
• Energy saving: When the radiator helps maintain a stable temperature, the system does not need to work in overheating conditions, thereby saving energy and reducing heat loss.

Types of Hydraulic Oil Radiators

Air-Cooled Hydraulic Oil Cooler

An air-cooled hydraulic oil cooler is a device used quite commonly in light to medium hydraulic systems, where oil pressure does not rise above 60°C.

The device also has many other names including: Air hydraulic cooling fan, air hydraulic oil heat exchanger.

The cooling fan will rotate when power is supplied. The fans rotate to push air through a metal radiator grid. The generated cool air will make the boiling oil be led back to the tank through a port. After the oil has shifted to a normal temperature, it will be led to the tank to start working.

The structure of an air hydraulic oil radiator is relatively similar to a normal civil fan. However, the air oil cooler has one unique difference: the radiator grid is made entirely of metal.

The device has one oil inlet and one oil outlet connected to the piping system. The discharge oil line of the air cooling system is the oil exit of the engine, hydraulic valve, or the oil exit from the system. After being cooled, the oil returns to the oil tank and prepares to start a completely new working cycle.

Advantages of air-cooled hydraulic oil coolers

• When using an air fan cooling system, the working reliability of the device is improved.
• Rectangular tank design, simple parts and components help with quick assembly and convenient transportation.
• The efficiency of hydraulic oil after being cooled will be higher.
• When installing oil radiators for mechanical devices and power stations, it helps with stable operation, avoiding machine shutdown or interruption.
• This device has few failures, so it limits expensive regular maintenance or repair costs.
• Eliminates coolants that cause dust buildup or corrosion from inside the device.
• The hydraulic oil temperature is maintained within certain limits by the cooling system, contributing to increasing the working efficiency of hydraulic dock leveler systems or industrial cargo lifts.

Water-Cooled Hydraulic Oil Cooler

For working environments where hydraulic oil is overheated and has a temperature above 60°C, using a water-cooled hydraulic oil cooler is a safe and high-efficiency measure.

Other names for water hydraulic oil coolers are: tube-type heat generator, hydraulic oil cooler, tube cooler, or tube radiator. Regardless of the name, this is a product that uses a cold water stream to reduce the temperature of hydraulic oil.

The function of a water-cooled hydraulic oil radiator is to lower the heat of hot oil before it returns to the engine to start a new working cycle.Regarding structure, oil coolers come in two basic forms: Tube type and plate type.

Normally, most customers will choose the tube type because the radiator has a relatively sleek and neat design. The structure of a tube-type hydraulic oil radiator is simply as follows:

• 2 oil lines: A line leading hydraulic oil back to the tank, a return oil line from the hydraulic valve before the oil goes to the tank.
• 2 water lines: One water line from the pump sucking from the tank, one outlet water line to return to the storage tank.
• The shell is made of stainless steel or alloy, copper to withstand pressure as well as oxidation and corrosion.
• The core of this device will be designed with many small copper tubes. They are arranged parallel to each other.

Advantages of water-cooled hydraulic oil radiators

• When choosing to buy, customers can choose many different water sources for cooling: hot water, stream water, filtered water.
• The product is very suitable for the tropical climate in Vietnam. When used, it does not cause much annoying noise, it is very smooth, and the machine operates gently.
• Thanks to the shell-and-tube design, users will minimize corrosion or shell cracking during use.
• Water-cooled hydraulic oil radiators are light in weight, not heavy, so they are very convenient to install and use for hydraulic devices and machines.
• Quick installation and high efficiency, easily lowering the temperature of industrial lubricants for systems and workshops operating at high capacity.
