12V Hydraulic Oil Cooler with Fan

When the hydraulic circuit of a mini-excavator runs hot, oil loses viscosity and movement precision drops. The 12V hydraulic oil cooler with fan addresses this by dissipating up to 720 kcal/h. Its aluminum alloy core uses a finned structure to increase the heat exchange surface without adding excessive weight.

Thermal Dissipation for Hydraulic Circuits

The integrated fan draws 48W at 12V and forces air through the core. The optimized air shroud boosts airflow, accelerating heat removal from the oil. Cooling is air-based, requiring no additional fluid in the existing system.

The mounting base features a reinforced weld. This design minimizes vibration transfer from the carrier machine and maintains radiator alignment over time. The aluminum alloy offers high thermal conductivity with a contained weight, a key factor for not overloading a mini-excavator under 2 tons.

Machine Integration Points

• Compatible oil flow: 10 L/min
• Fan supply: 12V, 48W
• Cooling capacity: 720 kcal/h
• Dimensions: 21 x 24 x 12.5 cm

The cooler connects to the hydraulic distributor return line, where oil is hottest before returning to the tank. This connection avoids routing the full pump flow through the cooler, which would reduce operating pressure.

For machines that heavily stress their hydraulic system, this part pairs well with other attachments like the hydraulic thumb or a 64 cm hydraulic crusher. On machines equipped with a hydraulic breaker, thermal stabilization becomes critical: the Norteck breaker generates heat spikes that this cooler helps contain.
