Cooling principle and precautions for industrial oil cooler

- Jul 06, 2019-

Industrial oil coolers are an oil cooling device commonly used in hydraulic systems and lubrication systems. The device can realize heat exchange between two fluid media with a certain temperature difference, thereby achieving the purpose of reducing oil temperature and ensuring normal operation of the system.


The water-cooled industrial oil cooler uses water as a medium and oil for heat exchange. In use, the heat medium is imported from the nozzle on the cylinder, and sequentially flows through the baffle passages to the outlet of the nozzle. The cold medium enters the half cooler tube through the water inlet cover through the water inlet cover, and then flows from the return water cover into the other half of the cooler tube to enter the other side water separation cover and the outlet water pipe. During the double-tube flow of the cold medium, the residual heat released by the absorbing heat medium is discharged from the water outlet, so that the working medium maintains the rated working temperature.


When the industrial oil cooler is used, the venting valve of the cooling line should be opened and closed after seeing the water to prevent the air resistance from affecting the cooling effect. When the line is stopped, stop the cooling water and open the cooling water vent valve to avoid damage to the equipment. When adjusting the temperature of the oil after cooling, the cooling water outlet valve should be controlled first.
