Excavator Radiator

A heat exchanger critical for cooling the engine of an excavator by dissipating heat from the engine's coolant to the ambient air, preventing overheating and ensuring optimal engine performance.

Types of Excavator Radiator

Copper/Brass Radiators: Traditional construction, good heat transfer, repairable.

Aluminum Radiators: Lighter, often more efficient due to fin design, widely used in modern excavators.

Bar & Plate Radiators: More robust and durable for heavy-duty applications, common in construction and off-highway equipment.

Tube & Fin Radiators: Lighter and more common for general-purpose cooling.

Applications in Various Industries:

Construction: Primary application in excavators, bulldozers, loaders, and other heavy equipment.

Mining: Used in mining excavators and machinery operating in harsh environments.

Agriculture: In large agricultural machinery like tractors.

Marine: In marine engines, though designs may differ.

Technology: 

Advanced fin designs for increased surface area and heat dissipation, durable core constructions to withstand vibration and impacts, often integrated with hydraulic oil coolers and charge air coolers (CAC) within the same assembly, pressure caps, overflow tanks, corrosion-resistant coatings.

Material Selection Considerations:

Core Material:

• Aluminum Alloys: Lightweight, excellent heat transfer, good corrosion resistance.
• Copper/Brass Alloys: Good heat transfer, good corrosion resistance, traditional choice.

• Tanks/Headers: Aluminum or plastic (fiberglass reinforced nylon) for lightweight and corrosion resistance.
• Fins: Thin aluminum or copper sheets for maximizing surface area.
• Tubes: Aluminum or copper for coolant flow.
• Gaskets/Seals: EPDM, silicone, or other temperature-resistant elastomers.
• Mounting Brackets: Steel for strength and vibration dampening.
• Protective Coatings: For corrosion and abrasion resistance in harsh environments.
