Custom Extruded Aluminum U Channel for Oil Cooler Lightweight High Thermal Conductivity
Product Overview
As a leading custom extruded aluminum U channel manufacturer, we engineer this extruded aluminum U channel specifically for the demanding environment of plate-fin oil coolers. Fabricated from premium 6061-T6 aluminum U channel alloys, this U-channel aluminum profile is precision-extruded to deliver an optimal balance of lightweight construction, high thermal conductivity, and long-term structural integrity. It functions as the essential framework and fluid pathway component within brazed heat exchanger assemblies.
Core Function
This structural aluminum U channel acts as both the flow channel frame and sealing bar in plate-fin oil coolers. It securely positions fins, defines independent oil and air passages, and forms the primary pressure-bearing architecture of the vacuum-brazed core.
Material Advantages
Crafted from 6xxx and 3xxx series aluminum U shaped channel alloys, this profile offers thermal transfer capabilities that significantly outperform steel or stainless steel alternatives. The material selection is fully optimized for vacuum brazing compatibility, providing superior corrosion resistance and ensuring leak-free operation throughout the product lifecycle.
Key Advantages
-
High Compatibility
Engineered for seamless integration with oil cooler brazing cycles. The alloy composition ensures excellent bonding with adjacent fins and partition plates, resulting in superior post-braze hermetic sealing.
-
Lightweight Construction
With a density roughly one-third that of steel, this aluminum U profile contributes to substantial weight reduction in finished oil coolers—a critical advantage for modern construction machinery and automotive thermal management systems.
-
Superior Thermal Efficiency
The inherent thermal conductivity of the aluminum channel profile ranges between 150 and 200 W/(m·K), driving a measurable increase in heat rejection and overall exchanger efficiency.
-
Flexible Customization
We accommodate full-process customization spanning cross-section geometry, alloy selection, and precision cut-to-length services. This agility allows for rapid response to unique oil cooler development specifications.
-
Integrated Raw Material Supply
Beyond the U-channel, we offer a comprehensive ecosystem of related aluminum materials, including fins, composite brazing sheets, and end caps, enabling a streamlined one-stop procurement experience.
