Tube And Fin Oil Cooler for Excavator

Tube And Fin Oil Cooler for Excavator

Widely used in excavators of various types and tonnages, including small, medium and large excavators, such as Komatsu PC series, Hitachi EX series, Volvo EC series, Kobelco SK series and many other brands of excavators often use tube-fin oil coolers.

When the excavator is working, the high-temperature engine oil enters the heat pipe through the oil pipe, contacts the surface of the heat pipe, and transfers the heat to the heat pipe. At the same time, the fins absorb the heat of the heat pipe through heat conduction and dissipate it to the surrounding air. If it is a water-cooled tube-fin oil cooler, the cooling water in the water tank will also flow around the heat pipe under the action of the water pump, further remove the heat through convection and conduction, and finally discharge the hot water to achieve the cooling of the engine oil.

Advantages

Efficient heat dissipation: The presence of the fins greatly increases the heat dissipation area and improves the heat dissipation efficiency. It can effectively dissipate the heat of the engine oil and ensure that the excavator can operate normally under high temperature conditions.

Simple structure: Compared with some other complex cooler structures, the structure of the tube-fin oil cooler is relatively simple, easy to manufacture, easy to realize assembly line production, and has low wind resistance, which is easy to arrange and install.

Easy to clean: The tube-fin structure makes the external surface area of the cooler larger, easy to clean, and can effectively prevent the accumulation of dust, debris, etc. from affecting the heat dissipation performance.

High reliability: Using high-quality pipe and fin materials, through reasonable design and manufacturing process, it can withstand the vibration, impact, high temperature, high pressure and other harsh conditions during the operation of the excavator, and has high reliability and stability.
