Description

Technical Field

[0001] The utility model relates to the field of oil coolers, in particular to an independent circulation heat exchanger. Background Art

[0002] Coolers are key devices used to reduce or control the temperature of a system or equipment. They remove heat from industrial processes or mechanical equipment through a heat transfer process to ensure that the system operates within a safe temperature range. Coolers are generally divided into two main types, including return oil cooling and independent circulation cooling. Return oil coolers are directly installed on the return oil pipeline of the hydraulic system to reduce the temperature of the hydraulic oil as it flows back to the tank. They are suitable for general industrial applications.

[0003] The independent circulation cooler transfers the heat of the hydraulic oil to the cooling medium through a separate cooling circuit, and then discharges the heat out of the system. It is suitable for high temperature environments or long-term operation. The correct selection and design of the cooler can effectively extend the life of the hydraulic system and equipment, reduce maintenance costs, and ensure stable operation and performance optimization of the system.

[0004] Although some equipment is equipped with an oil return cooler, the equipment is in a standby state after startup for a long time.

In this case, the hydraulic system cannot be cooled in time, which is easy to cause damage. Therefore, an independent circulation heat exchanger is proposed to solve the above problem.
