Microchannel Heat Exchanger OE 8136-04001-B for Dongfeng New Energy | Genuine Truck Part

This microchannel heat exchanger OE 8136-04001-B is manufactured in full compliance with Dongfeng New Energy three-electric system thermal design standards, adopting a full aluminum alloy parallel flow microchannel structure, with ultra-fine heat exchange tubes and high-density corrugated fins, greatly increasing the heat exchange area and improving cooling efficiency by more than 30% compared with traditional tube-fin condensers. The product adopts vacuum high-temperature brazing integrated forming process, with no welding gaps, no virtual welding, and strict pressure holding test to ensure zero refrigerant leakage and long-term sealing stability. The surface is treated with professional oxidation and anti-corrosion, which can resist moisture, salt spray and dust erosion in complex working conditions. The original mounting bracket and pipe interface design ensures perfect matching with the vehicle cooling system, no modification, no pipe bending, and quick installation, providing efficient and stable heat dissipation support for the new energy vehicle battery, motor and air conditioning system.

Fully compatible with all Dongfeng New Energy heavy-duty trucks equipped with microchannel cooling system, this heat exchanger can be accurately cross-checked via OE 8136-04001-B to ensure perfect interface and size matching. It solves a series of critical failures caused by inferior aftermarket heat exchangers, including poor aluminum material leading to easy corrosion and rupture, rough welding causing refrigerant leakage, low-efficiency fin structure resulting in poor heat dissipation, and mismatched interfaces leading to installation difficulty and pipeline stress. Insufficient heat dissipation will cause battery overheating, motor thermal attenuation, power reduction, air conditioning failure, and even trigger vehicle overheating protection and shutdown, seriously affecting the safety and endurance of new energy vehicles. By using this genuine heat exchanger, users can completely eliminate overheating, leakage, low efficiency and installation mismatch problems, restore the optimal working temperature of the three-electric system, and ensure the power performance and safety of the vehicle.

As a core component of the new energy vehicle thermal management system, this microchannel heat exchanger meets Q/DFL 6020-2021 Dongfeng automotive thermal parts standards and has passed authoritative third-party thermal efficiency, pressure resistance, salt spray corrosion and vibration fatigue tests. Test data shows that the product maintains stable heat exchange performance after 2.5MPa high-pressure holding test for 24 hours, no leakage, no deformation; after 500 hours of salt spray test, the aluminum surface has no obvious corrosion; after 10,000 hours of vehicle vibration simulation test, the welding part is intact. Each heat exchanger undergoes 100% full heat exchange efficiency detection, pressure leakage test and interface matching verification before leaving the factory, fully consistent with the original factory in material, structure, efficiency and installation performance. It adapts to plateau, high temperature, high humidity, coastal and other harsh operating environments, with reliable quality and long service life.
