Category description
Air-oil coolers and heat exchangers: types and operating principles
A hydraulic oil cooler is a device based on the principle of heat transfer from one fluid circulating within it to another fluid moving in the hydraulic system.
Operating Principle of a Heat Exchanger
In a hydraulic system, oil is subjected to heating in gear transmissions through the friction of moving elements of mechanisms. Cooling occurs in one of two ways: with water or air.
As a result, the following types of heat exchangers are identified::
- Air Heat Exchangers for Oil Cooling – used in stationary and mobile equipment. The operating principle of such devices is that the oil requiring cooling is pumped through a system of pipes, which are cooled by an airflow generated by a fan.
- Water Oil Coolers – used when it is necessary to cool the working fluid as effectively as possible.
- Autonomous Cooling Systems – used in the absence of a circulating cooling system.
- Chillers – devices for cooling fluid that use an absorption or vapor compression refrigeration cycle. After cooling in the chiller, the fluid is supplied to heat exchangers to reduce air temperature and remove heat from the equipment.
Heat Exchangers are Classified into Two Types Based on Purpose:
- Air-Oil Coolers. The oil entering them is cooled to a certain temperature level. Due to the temperature difference between the surrounding environment (air, water) and the oil, heat is transferred through the walls of the pipes from the fluid to the environment, leading to its cooling.
- Oil Heaters. Used in conditions where oil systems are employed and it is necessary to heat the working fluid above its initial temperature.
In Which Fields are Heat Exchangers Used?
In the agricultural sector, oil coolers are actively used in most equipment with hydraulic components. Heat exchangers are also employed in metal cutting, sheet bending, and other metalworking machines. Foundry installations, including high-temperature casting machines under high pressure, use such equipment.
Generally, any heavy machinery (road, construction, etc.) is equipped with a hydraulic heat exchanger. Since various excavators, cranes, and loaders almost always operate with overheated oil, they require its cooling.
Welcome to the website of Motorimpex! Here you can choose from air and water oil coolers, chillers and autonomous cooling systems. We provide complete information for technical specifications and detailed diagrams.
In our assortment you will find heat exchangers from such manufacturers as Hydac, Emmegi, OMT at affordable prices.
