Quiet Active Airflow and Conductive Heatsink Cooling for Closed-Screen Laptops

The innovative first-of-kind DHCx is specially designed, engineered and sculpted from solid aluminum to support and quietly cool current and prior generation Apple laptops.

The DHCx’s heatsink is carved from solid 6061 aluminum to create five cooling fins with four air channels cut to an incredible two inch depth, which provides the heatsink with a large surface area for improved heat transfer. The DHCx’s heatsink is made from continuous material with deep cooling fins to improve heat transfer, as well as improving heat flow within the heatsink mass. Compared to typical low-cost bolted or cast heatsinks, creating the DHCx’s heatsink requires higher precision, longer CNC milling times and higher costs.

The machined heatsink is then painstakingly finished by hand with sanding, bead-blasting and anodize to create a non-glossy matte finish with extra course texture for increased surface area, greater heat transfer and improved heatsink cooling efficiency. The heatsink’s laptop coupling plate has a specially prepared finish to produce a flat surface for improved heat transfer through a thermally conductive interface that couples with the laptop to efficiently extract heat while protecting the laptop’s finish. Edge pads wrap around all four sides of the heatsink’s coupling plate to protect the laptop from impact without heat transfer interference. The coupling system and padding is installed by hand onto the heatsink, and is made from the highest-quality and best performing materials to simultaneously transfer heat and protect the laptop.

The DHCx not only achieves high levels of heatsink cooling efficiency, but has a design optimized for Apple laptops. The DHCx’s heatsink is positioned at the laptop processor location to extract heat at the heat source. The overall support cradle width, heatsink coupling plate width and air channel locations match the laptop’s processor and built-in cooling system layout. The heatsink’s extra large central through-hole connects to a horizontal air channel with curving ends to supply cool air to the laptop’s center intake vent and flush out hot exhaust air for more efficient operation of the laptop’s built-in cooling system. The extra large through hole creates an open air space below the five vertical air channels to generate a passive current of cool air that continuously rises up to cool the five vertical cooling fins.

The DHCx’s air channels support silent passive cooling airflow, while a built-in cooling fan boosts heatsink cooling performance. The vertical air channels send cooling airflow upward to cool the laptop enclosure, and the internal angle guides cooling airflow down through the central through hole and front horizontal channel to flush out hot air and internally cool processors on laptops with a center intake vent, such as the 2021-2023 MacBook Pros, 2012-2015 MacBook Pros (Intel Retina) and 2010-2017 MacBook Airs (Intel non-Retina).

The DHCx and all Cooling Dock models work with the laptop operating in closed-screen clamshell mode while connected to one or more external monitors, external keyboard/mouse and power supply. All Cooling Dock models also feature a unique and stable leaning support for easy clamshell setup while the laptop remains connected to cables and safely in a padded cradle with adjustable/replaceable laptop retention pads (extra pads included for future setups).

All SVALT cooling systems use modular bolted / snapped assemblies and ship with the tools required for right-to-repair servicing, exchanging, upgrading and extending product life span.

SVALT designs innovative patented and/or patent pending products made locally in the Pacific Northwest with a focus on sustainability, and use solid aluminum for enduring metal construction.
