Q235A Large Cavity Heat-Dissipation Base | Integrated Mount Base for High-Power Module

Large box-type base made of Q235A steel via gantry CNC milling, with deep inner cavity & dense stepped cooling ribs. Applied as carrier for power modules & electrical control components; rib structure improves heat dissipation while reducing weight, peripheral flange holes for full enclosure assembly.

Core Specs

Industries: New energy electric control, high-power power supply, industrial control cabinet, frequency conversion equipment

Process: Q235 thick plate cutting → gantry CNC cavity roughing & finish milling → flange drilling/tapping → R-corner rounding → deburr → black oxide/paint finish

Precision: Cavity depth ±0.03mm, hole position ≤0.04mm, flatness ≤0.05mm, inner surface Ra3.2

Equipment: Gantry machining center, large CNC mill, CNC drill

Material: Q235A carbon steel, rigid & cost-effective for heavy base production

Post-processing: Deburr, radius chamfer, black oxide, anti-rust painting

Lead time: Samples7-9d, bulk12-20d

Advantages

✅ Inner multi-step ribs expand heat exchange area for efficient component cooling

✅ Full surrounding flange holes for uniform clamping & tight cabinet assembly

✅ One-piece solid plate avoids splicing gap with excellent anti-deformation rigidity

✅ Cost-efficient Q235 ideal for mass production of large equipment base

Solid steel cabinet base, inner ribs for superior heat dissipation; monolithic rigid structure, reliable carrier for power control modules.
