CNC Double-layer Heat Dissipation Plate

Product Overview

The CNC Double-layer Heat Dissipation Plate is a precision-engineered thermal management component designed for high-efficiency cooling in power electronics, industrial automation systems, and electronic control modules. Featuring a dual-layer structural design, it enhances heat transfer efficiency by increasing thermal conduction paths and expanding effective dissipation surface area. Manufactured using advanced CNC machining technology, it ensures excellent dimensional accuracy, stable mechanical strength, and reliable thermal performance.

Features

Manufactured with high-precision CNC milling, drilling, slotting, and surface finishing processes, the double-layer heat dissipation plate provides consistent structural alignment between upper and lower layers. The multi-layer architecture improves heat spreading efficiency and reduces localized thermal concentration in high-power applications. Reinforced bonding and integrated structural design ensure stability under continuous thermal cycling and mechanical vibration. Precision-machined mounting holes, thermal contact surfaces, and alignment features enable accurate assembly with electronic modules and cooling systems. Custom configurations are available for layer spacing, fin design, thickness, and mounting layout.

Materials & Manufacturing

Our CNC double-layer heat dissipation plates are manufactured from high-grade aluminum alloy and copper-based materials depending on thermal performance requirements. Aluminum alloys are widely used for their excellent balance of thermal conductivity, weight reduction, and machinability, while copper variants provide superior heat transfer capability for high-power systems. The production process includes CNC precision machining, multi-axis milling, surface leveling, deburring, and full dimensional inspection.

To enhance thermal efficiency and durability, we offer multiple surface treatments, including anodizing, hard anodizing, nickel plating, anti-oxidation coating, and thermal conductive finishes, ensuring long-term stability in demanding operating environments.
