Cooling System Controller Assembly OE 3613520-TE850 for Dongfeng New Energy | Genuine Truck Part

This cooling system controller assembly OE 3613520-TE850 adopts Dongfeng New Energy original intelligent thermal control program, which can collect real-time temperature signals of battery, motor, electric control and heat exchanger, and intelligently adjust the operating speed of cooling fan, water pump and solenoid valve to achieve optimal temperature control. The product is equipped with original customized waterproof connectors, including high-voltage blue plugs, signal plugs and power plugs, with perfect anti-loosening and waterproof structure, supporting true plug-and-play without wire cutting, welding or modification. The wiring harness is wrapped with flame-retardant, high-temperature resistant and wear-resistant corrugated pipe, and the internal copper core has excellent conductivity and low resistance. The controller shell adopts integrated heat dissipation design, which quickly dissipates heat and ensures long-term stable operation of electronic components, providing safe and intelligent control for the new energy vehicle cooling system.

Fully compatible with all Dongfeng New Energy heavy-duty trucks equipped with an intelligent cooling system, this controller can be accurately matched via OE 3613520-TE850 to ensure complete protocol consistency. It solves a series of critical failures caused by inferior aftermarket controllers, including incompatible communication protocol leading to system mismatch, unstable chip leading to frequent fault codes, poor waterproof performance causing short circuit, and low-quality harness leading to poor contact and signal interruption. Once the cooling controller fails, the whole vehicle thermal management will be paralyzed, resulting in battery overheating, motor power attenuation, instrument alarm and even mandatory limited speed or shutdown, which seriously affects the safety and endurance of new energy vehicles. By using this genuine controller, users can completely eliminate cooling malfunction, overheating fault, communication error and poor contact problems, and restore the normal intelligent thermal management function of the vehicle.

As a core electronic control component of the new energy three-electric system, this cooling controller assembly meets Q/DFL 6020-2021 Dongfeng automotive electronic parts standards and has passed authoritative third-party tests for waterproof, shockproof, high and low temperature resistance, anti-electromagnetic interference and signal stability. Test data shows that the product passes IP67 waterproof and dustproof test, 24V voltage stabilization test, 1000-hour continuous high-temperature aging test, and maintains stable signal output and control function under vehicle vibration simulation. Each controller undergoes 100% communication matching detection, connector plugging test, harness continuity test and function debugging before leaving the factory, fully consistent with the original factory in protocol, performance, interface and service life. It adapts to plateau, high humidity, cold and high-temperature environments, with reliable quality and long service life.
