1. Core Function: Controlling Transmission Oil Temperature
As the core component of the transmission thermal management system, the 1301200V5080 oil cooler assembly undertakes the key function of regulating the temperature of transmission oil. When the transmission operates, friction between gears, clutches, and other components generates a large amount of heat, causing the oil temperature to rise. The high-temperature oil is pumped into the cooler core through the oil inlet, and heat is transferred to the cooling medium (air or cooling water) through the aluminum alloy micro-channels and fins. The cooled oil then flows back to the transmission through the oil outlet, forming a closed-loop heat dissipation cycle. This function ensures that the transmission oil always maintains appropriate viscosity and lubricating performance, avoiding accelerated wear of internal components due to overheating.
2. Protecting Transmission Components from Wear and Failure
By stabilizing the oil temperature, the 1301200V5080 oil cooler assembly effectively protects the transmission from premature wear and failure. When the oil temperature is too high, the oil’s lubricating film is easily broken, leading to direct metal-to-metal contact between gears and clutches, resulting in severe wear and even tooth breakage. The cooler prevents this by quickly dissipating heat, ensuring the oil’s lubricating film remains intact. Additionally, high temperatures can cause oxidation and deterioration of the oil, producing sludge and carbon deposits that block oil passages and damage hydraulic control valves. The cooler’s temperature control function slows down the oil oxidation rate, extending the oil change interval by 30-50% and reducing the risk of component failure caused by oil deterioration.
1. High-Efficiency Heat Dissipation for Stable Oil Temperature
The 1301200V5080 transmission oil cooler assembly adopts an advanced parallel-flow core structure, with a heat dissipation area expanded by 35% compared to traditional series-flow coolers. Its core is composed of multi-layer aluminum alloy micro-channels (channel width: 1.2-1.5 mm), which significantly increases the contact area between transmission oil and the cooling medium. Equipped with a high-density fin design (fin density: 18 fins per inch) and a low-resistance internal flow path, the assembly achieves a heat dissipation efficiency of up to 88% under rated working conditions. Even when the transmission is operating under high loads (such as long uphill driving, heavy-duty towing, or continuous high-speed running), it can quickly reduce the oil temperature—maintaining the transmission oil within the optimal working range of 80-110°C, effectively avoiding oil viscosity reduction and performance degradation caused by overheating.
2. Durable Material and Structural Design for Long Service Life
The key components of this oil cooler assembly are made of high-strength 3003 aluminum alloy, which has excellent corrosion resistance and fatigue resistance. The core undergoes a vacuum brazing process, ensuring a tight connection between the micro-channels and fins with a leakage rate of less than 1×10⁻⁹ Pa·m³/s. The outer shell is treated with a ceramic-based anti-corrosion coating (thickness: 5-8 μm), which can resist corrosion from road salt, rainwater, and chemical pollutants—passing 1500-hour neutral salt spray testing. Additionally, the assembly is designed with a shock-absorbing mounting bracket, which reduces the impact of vehicle vibration on the cooler core by 40%, avoiding structural damage caused by long-term vibration and extending the overall service life to more than 8 years or 200,000 kilometers.
