Custom CNC Machining Aluminum Dense Fin Heat Sink For Power Electronic Equipment

Quick detail

Custom‑machined aluminum heat sink adopts dense fin structure for enlarged heat exchange area. Processed by high‑precision CNC milling, it keeps uniform fin spacing and avoids thin‑wall deformation. Suitable for new energy control modules and industrial power supply units. Supports prototype and batch production with full dimensional inspection.

Product description

This custom aluminum alloy heat sink is engineered for high‑power power electronic devices. Dense parallel‑arranged fins expand effective heat dissipation area, helping equipment maintain stable working temperature under continuous operation. Our CNC milling process strictly controls fin flatness and spacing consistency, reducing the risk of thin fin bending during production. Multiple surface finishing options are available to match different working environment requirements.
