Product overview and where it fits
The SimtoLink finned die-cast aluminum enclosure uses die-cast aluminum fins to add convection area. It holds an edge AI accelerator, a power module, or a high-power communications unit, and it keeps junction temperature in check inside a closed or semi-outdoor cabinet.
The table also lists material and thermal-path options. The temperature rise depends on air speed, mounting orientation, and the gap to the next module. Use the thermal-resistance model and the measured curves in the hardware specification.
Reliability on site
Dust on the fins cuts cooling sharply. Outdoors, set a blow-off or wash procedure, and keep the electrical safety rules in that procedure.
Fit the thermal pad or phase-change material between the die-cast shell and the power devices to the stated torque. Creep otherwise raises the thermal resistance.
Key hardware parameters
The ratings below are the typical build of this enclosure, written so a specifier can cite them in a bid clause. For a wider range, redundant power, or an intrinsically safe variant, ask SimtoLink for the hardware specification and the installation and commissioning guide. Order codes in the same family can differ slightly; the nameplate and the documents in the box govern.

Typical applications
Four field patterns for this enclosure, useful when you are laying out a cabinet and checking payback:
Edge AI inference box
Heat from an NPU or GPU module leaves through the shell.
Cover for a high-power DC module
The rectifier or converter and the heatsink are one structure.
Outdoor small-cell auxiliary box
The RRU supply and the interface gear share one shell and one cooling path.
Hot-zone split in a cabinet
The hot subsystem sits apart from a PLC that cannot take the heat.
Installation, grounding, and maintenance
- Point the fins with the cabinet airflow, and do not let a harness cover them.
- Replace aged thermal-interface material on the cycle, and clean the contact faces when you take the unit apart.
- When the shell must be bonded, do not paint the fins or the earth terminal.
- A wash is done with the unit powered off, and it is fully dry before power returns.
- Watch shell temperature and the hot spot. Above the threshold, shed load or add a fan.
Ordering, documents, and support
SimtoLink supplies the hardware specification, dimension drawings, a wiring table, and sample projects for this enclosure. Volume orders can include a sample review and in-plant inspection. Warranty and calibration follow the contract and the documents shipped with the unit.
