Hydraulic systems generate a lot of heat due to the friction and resistance of moving parts, which can cause the hydraulic fluid to become too hot. If the hydraulic fluid becomes too hot, it can break down, lose its lubricating properties, and damage the hydraulic system components.
To prevent this from happening, hydraulic systems often use an oil cooler, which is a heat exchanger that removes excess heat from the hydraulic fluid. The oil cooler circulates cool air or coolant around the hydraulic fluid, which helps to reduce the temperature and maintain the fluid’s performance and lubricating properties.
An oil cooler is particularly important in hydraulic systems that operate under high loads, high pressures, or continuous operation, as these conditions can generate more heat and put more stress on the system. By using an oil cooler, hydraulic systems can operate more efficiently, last longer, and require less maintenance.
