Product Description

Black Sprayed Split Double Circuit Multi Port Horizontal Fin Combined Cooling Radiator

Black Sprayed Split Double-Circuit Multi-Port Horizontal Fin Combined Cooling Radiator
Heavy-duty construction machinery cooling radiator with full specification support for large excavators, heavy loaders, and mining engineering vehicles.
Product Overview
This matte black electrostatic coated split double-layer integrated cooling radiator is specifically developed for large excavators, heavy loaders, and mining engineering vehicles. The unit integrates engine water cooling and hydraulic oil cooling circuits into a single assembly, featuring independent flow channels with upper water cooling core and lower hydraulic oil cooling core.
Four main large-caliber pipe joints are distributed on left and right side plates, complemented by multiple small auxiliary threaded ports for exhaust, pressure monitoring, and overflow. Two top hanging lugs facilitate overall hoisting installation. Horizontal louver turbulence fins are vacuum brazed separately for water and oil passages, with complete surface treatment using high-temperature black anti-rust coating to resist mud, dust, and acid-base corrosion on construction sites.
Core Feature Highlights
  • Split Double Independent Circuit Design: Upper engine water radiator + lower hydraulic oil cooler integrated with completely isolated flow channels, eliminating cross-leakage while solving both engine overheating and hydraulic high temperature problems
  • Multi-Port Asymmetric Joint Layout: Independent large pipe ports for water inlet/outlet and oil inlet/outlet, plus reserved auxiliary test and exhaust screw ports for convenient on-site maintenance and pipeline debugging
  • Integral Matte Black High-Temperature Anti-Corrosion Coating: Isolates aluminum substrate from construction site mud, rain, and corrosive dust, effectively preventing surface oxidation discoloration and scratch damage
  • Dual Top Hanging Lugs for Overall Hoisting: One-piece lifting installation eliminates separate disassembly of water and oil cooling cores, significantly improving assembly efficiency for engineering machinery OEM factories
  • High-Density Horizontal Interleaved Louver Fin Array: Layered heat exchange structure with large heat dissipation area ensures stable cooling performance under 24-hour continuous heavy-load mining and earthmoving construction

Applicable Working Environment
Item Requirement Standard
Ambient Temperature Range -50℃ ~ +85℃
Relative Humidity 2%–100% harsh mine & earthwork site environment with mud, gravel impact, cement dust, rainwater soaking and high-frequency violent vibration
Installation Position Overall hoisting fixed installation at the front of heavy construction machinery engine compartment
Working Condition Long-time uninterrupted full-load excavation, loading and mining operation, simultaneous heat generation of engine and hydraulic pump, frequent instantaneous pressure impact
Environmental Resistance Black coating provides dual anti-rust and anti-scratch protection, horizontal fin gaps can be directly flushed with high-pressure water gun to remove accumulated mud and dust
Product Competitive Advantages
  • Material Advantage: Thickened side plate and joint base with black coating provide strong anti-collision and anti-corrosion performance, adapting to long-term severe construction site working conditions and significantly extending service life compared to bare aluminum coolers
  • Process Advantage: Water and oil dual cores adopt independent vacuum brazing process with completely separate flow channels, double pressure tightness test before delivery eliminates hidden cross-leakage troubles
  • Layout Advantage: All-in-one combined cooling assembly reduces quantity of independent cooling accessories, shortening OEM production line assembly cycle; top hanging lugs enable fast disassembly and replacement during after-sales maintenance
  • Quality Control: Each radiator completes dual water-oil channel high-pressure tightness test; calibration of coating uniformity, joint concentricity and hanging lug position before factory delivery
  • Customization Advantage: Supports adjustment of upper/lower core proportion, joint thread specification, auxiliary port quantity and coating color as per drawings; factory direct batch supply with complete model specifications and formal VAT invoices; suitable for heavy construction machinery OEM supporting and large mine maintenance stations bulk procurement
Target Market & Customer Groups
Main sales regions: Domestic heavy mining & construction machinery OEM manufacturers, large engineering vehicle maintenance bases, construction machinery radiator supporting factories, cross-border heavy equipment spare parts merchants in Southeast Asia, Africa and Central Asia.
Core customers: Large excavator/mining loader complete vehicle manufacturers, integrated cooling system supporting manufacturers, mine engineering equipment after-sales maintenance enterprises.
