Technical Summary of Oil Cooler Specifications and Performance Parameters

1. Specific Heat Transfer (kW/°C)

The document provides specific heat transfer values for various oil coolers, indicating their thermal performance efficiency. These values are essential for selecting appropriate coolers based on heat dissipation requirements.

2. Oil Flow Rates (Qoil in L/min)

Oil flow rates are categorized into standard and "E" range oil coolers, with the following ranges:

• Standard range: 40 to 230 L/min
• "E" range: 20 to 140 L/min, 12 to 75 L/min, and 8 to 46 L/min depending on model

Specific models listed include E135-564-4, E135-411-4, E135-283-4, E110-564-4, E110-330-4, E110-241-4, E083-411-4, E083-283-4, E083-196-4, E065-411-4, E065-241-4, and E065-161-4.

3. Pressure Drop (DPoil)

The pressure drop across the oil cooler is specified at 250 mbar and 2000 mbar, measured with SAE-10 oil at 60°C. This parameter is critical for understanding the resistance to flow and ensuring system compatibility.

4. Water Flow Rate (Qw)

Water flow rates are indicated with ranges from 8 to 230 L/min, corresponding to different cooler models and configurations.

5. Temperature Parameters (Ptoil in - Tw in)

The document includes temperature-related parameters, likely representing oil inlet temperature (Ptoil) and water inlet temperature (Tw), with values ranging from 10°C to 300°C. These are important for thermal performance calculations.

6. Version and Notes

The data corresponds to Version 03.2018. It is noted that the guide values are subject to change without notice, and users are advised to contact the supplier to confirm selections based on thermal specifications.

Critical Information and Recommendations

• Selection of oil coolers should consider specific heat transfer rates and flow capacities to match system requirements.
• Pressure drop values must be accounted for to avoid excessive flow resistance.
• Temperature ranges should be verified to ensure compatibility with operating conditions.
• Consultation with the supplier is recommended to confirm the latest specifications and ensure optimal cooler selection.
