The CAT 7W4245/2W36045 radiator is designed specifically for the 789 mining truck, ensuring stable and efficient cooling during ultra-large haul operations. This radiator utilizes a highly efficient heat exchange structure combining copper tubes and aluminum fins. Advanced mechanical expansion and precision brazing processes ensure a tight connection between the tubes and fins, providing excellent thermal conductivity and significantly improving heat dissipation efficiency. Its operating principle, based on forced convection combined with large fins, rapidly transfers coolant heat to the air, effectively maintaining a suitable engine temperature under extreme operating conditions.
Features
Designed for rugged mining environments, effectively resisting long-term, intense vibration.
