This алюминиевый радиатор для Seeed Studio XIAO covers 20 x 20 x 10 mm in 6061-T6 aluminium, with 22 mm fins at 2.0 mm pitch. Thermal performance is 0.35 K/W at ΔT = 60 K, confirmed by CMM 0.001 mm resolution, with zinc-nickel plating, trivalent passivation available.
Stamping gives a repeatable 1.0 mm fin profile that extrusion cannot hold: the die forms every fin in one stroke, so pitch stays within ±0.05 mm across a 120,000 pcs run.

Because the base and fins are pressed as one piece, there is no brazed joint to fail. 0.05 mm over 100 mm flatness on the mounting face is held directly from the tool, which keeps thermal interface contact uniform.
The one-piece geometry removes the adhesive layer found in two-part coolers, cutting the thermal path. Nothing sits between 6061-T6 aluminium and the airflow except the stamped surface itself.

Stamped construction tolerates batch variation better than extrusion: die wear shows up first as a measurable shift in fin pitch, which inspection catches at CMM 0.001 mm resolution rather than in the field.
One supplier now covers 1.0 mm to 1.0 mm fin gauges from the same 160 T press family, so a thermal redesign is a tooling change rather than a new vendor.

The standard material is 6061-T6 aluminium, supplied with zinc-nickel plating, trivalent passivation. For applications where EV and OBC charger exposure is a concern, we recommend the passivated route; where conductivity matters more than weight, copper C110 raises thermal performance and roughly doubles unit mass.

General dimensions run to ±0.10 mm, with critical features such as ±0.03 mm on fin pitch held separately. Formed geometry inherits tooling repeatability of ±0.05 mm, and hole position is held to ±0.10 mm. Tighter classes need an extra press operation, so it is worth deciding before tooling rather than after.
Flatness is checked on a granite surface plate, 20 °C against a 0.05 mm over 100 mm limit, and fin pitch is verified optically at ±0.05 mm. Reports go out with each lot.
Sampling is AQL 0.65 for critical dimensions and 1.5 for general, with CMM 0.001 mm resolution on every first article. Deviations beyond ±0.10 mm trigger a full-lot sort.
We inspect 1.0 mm fin tips for burr and crack after forming, because stamping can split a root without shifting any drawing dimension. Burr limit is set per part.
Final containment is PE bag + export carton, 20 kg per carton. Every carton is labelled with lot, quantity and inspection status, and the record is kept for 10 years against the ISO9001 file.
In EV and OBC charger, the 0.35 K/W rating determines how much airflow the enclosure still needs. At EV and OBC charger junction temperatures, 1.0 mm fins at 2.0 mm pitch keep the delta-T inside the sensor budget.

EV and OBC charger programs are the reason this geometry exists. Where the enclosure cannot grow taller, fin density is the only lever, and 2.0 mm pitch with 1.0 mm stock is the practical ceiling for aluminium.

In EV and OBC charger, the base usually doubles as the mounting interface. 1.5 mm with 0.05 mm over 100 mm flat gives a stable surface for the EV and OBC charger thermal pad.
EV and OBC charger designs often run a 2.0 m/s forced-air path. 0.35 K/W at ΔT = 60 K, natural convection means EV and OBC charger can hold its target with fan power below the acoustic limit.

MOQ is 50 pcs for a prototype run and 1000 pcs for production. Below the prototype quantity the tooling amortisation dominates the unit cost, so we quote the sample route instead: sample fee 30-80 USD.

On 6061-T6 aluminium at normal press tonnage, expect a tooling life of roughly . At 120,000 pcs that is 6 to 12 months. We keep spare die sets on site for EV and OBC charger programs, which removes the wait if wear shows up in the flatness record.
Standard packing is PE bag + export carton, 20 kg per carton. We quote FOB Shenzhen. Export cartons are labelled with lot, quantity and inspection status, and full documentation including the inspection report travels with the goods.
Yes. Send your enclosure airflow, inlet temperature and the heat load to be dissipated, and we will run a steady-state model and return a suggested 1.0 mm and 2.0 mm combination. That usually saves one tooling iteration.
Skived fins are milled, so you get thin, tall fins and higher density in a given height, but the cost scales directly with fin area. Stamping gives the same result in one stroke at a much lower unit cost below 120,000 pcs. For EV and OBC charger in a fixed-height enclosure, stamped is normally the right answer.
Tooling is built in-house, which is how ±0.05 mm is held across a 120,000 pcs programme rather than drifting part by part.
Production runs on 8 s cycles with in-line vision on 0.05 mm over 100 mm. That is what keeps a 120,000 pcs commitment credible in peak season.
Quality staff sit beside the press, not in a separate room. Deviations on 2.0 mm or 0.05 mm over 100 mm stop the run at the tool rather than at final inspection.
