Specification

Description

This heat exchanger core fits 3304 and 3306 series excavator engines with part number 9Y-3333 / 9Y3333, acting as a core replacement component for engine cooling systems. It is integrally welded with copper heat exchange tubes, stainless steel flanges and tube sheets. The tube bundles are fixed and supported in layers, with densely arranged through holes on both end sealing tube sheets. Featuring a neat and compact structure, it is specially designed for heat exchange between engine oil and coolant. It matches the assembly dimensions of original engineering machinery cooling assemblies and can directly replace damaged old cores.

Advantage

Copper heat exchange tubes feature high thermal conductivity, delivering far better heat exchange efficiency than ordinary iron tubes with stable temperature control.
Integral brazing sealing process eliminates leakage between tube sheets and copper tubes, resisting corrosion from engine oil and coolant to prevent fluid leaks.
Multi-layer metal support rings secure tube bundles, preventing tube deformation and fracture under intense vibration of construction vehicles for extended service life.
Mounting holes on flanges, overall tube length and hole layout strictly follow original standard sizes, allowing plug-and-play replacement without modification for easy installation and disassembly.
High temperature and pressure impact resistance, suitable for harsh working conditions of heavy-load and long-hour continuous excavator operation.
Integrated forming structure provides even heat dissipation channels, less prone to scaling and clogging for easier maintenance and cleaning.

Performance

Efficient Heat Conduction: Pure copper tube bundles offer outstanding heat transfer performance to rapidly dissipate excess heat from engine oil, stabilize operating oil temperature and avoid cylinder scoring caused by overheating.
Pressure Resistance & Tight Sealing: Standard industrial brazing withstands standard working pressure of engine cooling systems with zero leakage under cyclic high and low temperature environments.
Vibration Resistant & Durable: Segmented reinforced support adapts to bumpy construction sites and continuous vibration without loose tube bundles during long-term service.
Wide Compatibility: Precisely matches dimensional parameters of 9Y-3333, perfectly compatible with cooling systems of 3304 and 3306 excavator engines.
Anti-corrosion & Anti-oxidation: Anti-oxidation treatment on copper tubes resists chemical corrosion from coolant and engine oil to reduce internal scaling.
Reliable Heat Dissipation Range: Maintains safe oil temperature under full-load continuous engine operation, effectively extending the overall service life of the engine.
