A brief introduction to the oil cooler

Oil coolers can be classified into air-cooled oil coolers and water-cooled oil coolers depending on the medium of heat exchange, and are mainly used to cool hydraulic oil and lubricating oil. Oil coolers are widely used in plastic machinery, engineering machinery, mining machinery, automobiless, steel, wind power, aerospace and other industries.

There are many types of oil coolers. The water-cooled oil coolers are divided into tubular oil coolers and plate oil coolers. The plate oil coolers are further divided into detachable plate oil coolers (removable plate heat exchangers) and brazing. Welded plate oil cooler (brazing plate heat exchanger); air-cooled oil cooler is divided into tube type and plate fin type.

Hydraulic systems and lubrication systems are an important part of every machine. The hydraulic system needs to maintain a high pressure continuously while working, which generates a large amount of heat, and the oil temperature rises after a long period of work. If the heat is not released in time, the sealing components of the system will be deteriorated and damaged, and the viscosity of the oil will become lower as the oil temperature rises, and the oil pressure will not meet the requirements of the work. To ensure safe and reliable operation of the unit. The oil temperature must be controlled within the specified range. Although the main reason for the increase in the oil temperature of the lubrication system is different from that of the hydraulic system, it is also necessary to control the oil temperature within the specified range.

Characteristics of the oil cooler (introduction):
1. Water-cooled oil cooler uses water as medium and oil for heat exchange. The advantage is that the cooling effect is better, which can meet the requirements of lower oil temperature (the oil temperature can be reduced to about 40 °C. The disadvantage is that there must be water source) The place can be used.

2. The air-cooled oil cooler uses air as the medium and oil for heat exchange. The advantage is that air is used as the cooling source, which is basically not restricted to use. It is also environmentally friendly. The disadvantage is that it is affected by the ambient temperature and the temperature is higher. When the temperature of the oil can not be lowered to the desired temperature (it is difficult to reduce the temperature of the oil to only 5~10 °C above the ambient temperature).
