Product Overview
Custom aluminum radiator extrusions are Ruhai’s OEM service: your thermal layout becomes a single extruded profile with the exact fin geometry, bores and mounting features your product needs.
One extrusion replaces welded plate stacks and bolted heatsinks — fewer parts, lower contact resistance, cleaner look. We support from prototype die runs to mass production with stable annual pricing.
Key Features
