Thermal Management

Modern high-wattage GaN chargers and workstation power supplies generate significant heat during AC/DC conversion. How you mount them matters.

The Ambient Trap

Power adapters are designed to dissipate heat into ambient air via their casing. When multiple adapters are stacked together in a narrow wire tray or plastic channel, their localized ambient temperature rises drastically.

A 140W charger operating at 90% efficiency dissipates 14W as pure heat. Three such adapters piled together create a 42W thermal core in a confined space. This leads to component degradation and thermal throttling (where the charger reduces output to prevent melting).

SCB Thermal Strategy

  • 01
    Mandatory Spacing

    Grid mounting forces physical separation between heat sources, allowing natural convection to cool each brick individually.

  • 02
    Thermal Mass

    The aluminum PDU spine acts as a massive 3-pound heatsink for the integrated power circuitry.
