This sheet metal enclosure is stamped from SECC 1.0 mm with fins at pitch, giving a measured thermal resistance at ΔT = 60 K. The base holds tolerance verified on a granite plate, and the assembly runs at capacity per month from a single ISO9001 line in Dongguan. Stamping holds fin pitch within tolerance across a run, and the one-piece geometry removes the adhesive layer found in two-part coolers, cutting the thermal path.

Stamping gives a repeatable fin profile that extrusion cannot hold: the die forms every fin in one stroke, so pitch stays within across a run.
A single stroke forms the whole sheet metal enclosure, so part cost stops scaling with complexity. Tooling runs , and the cycle feeds a line.
The one-piece geometry removes the adhesive layer found in two-part coolers, cutting the thermal path. Nothing sits between SECC 1.0 mm and the airflow except the stamped surface itself.
Pressing SECC 1.0 mm keeps the sheet metal enclosure light, from depending on envelope, without sacrificing fin density, which matters where airflow path length is already fixed by the enclosure.
The powder coating RAL 9005 finish is applied after forming, so corrosion protection does not get cut through at the fin roots the way it does on machined alternatives.

The standard material is SECC 1.0 mm, supplied with powder coating RAL 9005. For applications where solar tracker 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 , with critical features such as held separately. Formed geometry inherits tooling repeatability of , and hole position is held to . Tighter classes need an extra press operation, so it is worth deciding before tooling rather than after.

Flatness is checked on a against a limit, and fin pitch is verified optically at . Reports go out with each lot.
Incoming SECC 1.0 mm is checked for thickness and hardness before it enters the press. After forming, confirms and against the drawing.
Sampling is AQL 0.65 for critical dimensions and 1.5 for general, with on every first article. Deviations beyond trigger a full-lot sort.
Final containment is . Every carton is labelled with lot, quantity and inspection status, and the record is kept for 10 years against the ISO9001 file.

solar tracker programs are the reason this geometry exists. Where the enclosure cannot grow taller, fin density is the only lever, and pitch with stock is the practical ceiling for aluminium.
For solar tracker builds, the mounting face matters as much as the thermal rating: it decides whether thermal interface material spreads evenly or pools at one end.
In solar tracker, the base usually doubles as the mounting interface. with flat gives a stable surface for the solar tracker thermal pad.
Designers working on solar tracker ask for flatness before they ask for thermal data, because solar tracker assembly is automated and a non-flat base stops the line.

General dimensions run to ; critical ones such as are held separately. Formed features inherit tooling repeatability of . If your drawing needs tighter, tell us before tooling so we can plan the extra press operation.
Yes, we ship as-pressed for customers who do their own finishing. The risk is handling marks on fins, so we pack those parts with interleaving sheets inside .
Standard packing is . We quote . Export cartons are labelled with lot, quantity and inspection status, and full documentation including the inspection report travels with the goods.
Yes. We can add clips, screws or a fan shroud as a kitted assembly, with the parts bagged and labelled per set. This is common in solar tracker programs and adds about 3 working days.
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 and combination. That usually saves one tooling iteration.
Our solar tracker experience runs back to the first tooling programme in 2015. That history is why the standard powder coating RAL 9005 and are conservative rather than optimistic.
Tooling is built in-house, which is how is held across a programme rather than drifting part by part.

The standard material is SECC 1.0 mm. This steel sheet is stamped in one stroke, so the fin profile stays repeatable and the pitch remains within tolerance across a production run. The SECC substrate also accepts the RAL 9005 powder coating applied after forming.
The die forms every fin in one stroke, so pitch stays within tolerance across a run. Stamping gives a repeatable fin profile that extrusion cannot hold. This means the thermal resistance at ΔT = 60 K remains consistent from part to part on the ISO9001 line in Dongguan.
The measured thermal resistance is at ΔT = 60 K. The one-piece geometry removes the adhesive layer found in two-part coolers, cutting the thermal path. Nothing sits between SECC 1.0 mm and the airflow except the stamped surface itself, which supports consistent heat transfer.

The powder coating RAL 9005 finish is applied after forming. This means corrosion protection does not get cut through at the fin roots the way it does on machined alternatives. The standard material is SECC 1.0 mm, and the coating is compatible with the stamped fin geometry.
The assembly runs at capacity per month from a single ISO9001 line in Dongguan. Tooling runs and the cycle feeds a line, so production scales with the stamping process. A single stroke forms the whole sheet metal enclosure, so part cost stops scaling with complexity.

It is stamped from SECC 1.0 mm steel. This material provides a balance of formability, strength, and cost for stamped fin geometries. The one-piece construction removes the adhesive layer found in two-part coolers, cutting the thermal path.
The article states a measured thermal resistance at ΔT = 60 K, but the exact value is not provided in the excerpt. For a specific figure, request the test report. The one-piece stamped design helps minimize the thermal path.
