Oil cooler

The Baode DOC Oil Cooler is a high-performance heat exchanger designed to efficiently transfer heat between oil and coolant. These compact units provide exceptional thermal performance, helping reduce operating costs by minimizing the amount of cooling water required. Their lightweight design and compact dimensions make them ideal for industries where space constraints and efficiency are paramount.

Manufactured from high-quality stainless steel AISI 316 (1.4401) and vacuum-brazed with copper or nickel, these oil coolers offer excellent mechanical strength and resistance to corrosion. With options for nickel and stainless brazing, the Baode DOC Oil Coolers can be adapted to meet the demanding requirements of various applications, including industrial cooling, automotive systems, and hydraulic circuits.

How the Baode DOC Oil Cooler Works

The oil cooler functions by transferring heat from hot oil to a cooling medium such as water glycol, water, or HFC operating fluids. As the hot oil flows through one set of channels and the coolant flows through adjacent channels in the brazed plate heat exchanger (BPHE), heat is transferred between the two fluids without mixing.

The corrugated plate design creates turbulence within the fluid streams, enhancing heat transfer efficiency. This turbulence improves mixing and prevents stagnant zones, ensuring consistent thermal performance. Thanks to the compact size and lightweight construction, these coolers are easy to install and integrate into various industrial and automotive systems.

Key Features of the Baode DOC Oil Cooler

1. High-Efficiency Thermal Transfer
   The turbulent flow paths within the exchanger’s plates ensure optimal heat transfer, reducing the amount of coolant needed. This efficiency helps lower operating costs by minimizing energy consumption and the demand for cooling water.

2. Compact and Lightweight Design
   The oil cooler’s small footprint makes it suitable for installations with space constraints. Despite its compact size, the oil cooler offers high mechanical strength, allowing it to perform reliably in demanding environments.

3. Durable Stainless-Steel Construction
   The plates and connections are made from AISI 316 stainless steel, which ensures high corrosion resistance and durability. This makes the oil cooler ideal for use in harsh environments, such as marine or industrial applications.

4. Nickel and Stainless Brazing Options
   For applications that require greater corrosion resistance, nickel or stainless brazing options are available, extending the life of the exchanger even in aggressive fluid environments.

5. Vacuum-Brazed Joints for Leak-Free Operation
   The brazing process creates leak-proof joints between the plates, ensuring reliable performance under high pressure and reducing the risk of cross-contamination between fluids.

Operating Conditions and Fluid Compatibility

The Baode DOC Oil Cooler is designed to operate across a wide range of temperatures and pressures, ensuring versatility and reliability in various industrial and commercial applications.

Operating Media

The oil cooler is compatible with several cooling and lubricating fluids, including:

• Water glycol mixtures (used in many industrial cooling systems)
• HFC operating fluids
• Water
• Oil

These media ensure optimal cooling for hydraulic circuits, automotive systems, and industrial processes.

Temperature Range

The heat exchanger can withstand temperatures ranging from 50°F to 437°F (10°C to 225°C). However, the freezing and boiling points of the fluids used must be carefully considered to prevent damage to the unit.

Pressure Ratings

• Maximum Design Pressure: 30 to 45 bar
• Test Pressure: 45 to 60 bar

These pressure ratings ensure the oil cooler can handle high-pressure systems, such as automotive engines and industrial equipment.

Fluid Contamination and Corrosion Limits

For optimal performance and longevity, it is important to maintain fluid purity and follow the recommended contamination limits:

• Suspended particles: <10 mg/l
• Maximum particle size: <0.6 mm (spherical)
• Thread-like particles: Should be avoided, as they can cause rapid increases in pressure drops.

Corrosion Resistance and Chemical Limits

To prevent corrosion and ensure the longevity of the oil cooler, the following chemical limits should be observed:

• Chlorine (CL₂): < 0.5 ppm
• Chloride Ions (CL⁻):
  • < 700 ppm at 20°C
  • < 200 ppm at 50°C
• Sulphate (SO₄²⁻): < 100 ppm
• Ammonia (NH₃): < 10 ppm
• Free CO: < 10 ppm

The unit is resistant to common ions like phosphate, nitrate, nitrite, iron, manganese, sodium, and potassium under normal conditions, ensuring safe and reliable operation in various environments. It is recommended to maintain a pH level between 7 and 10 to prevent chemical degradation of the materials.
