The DHCR Cooling Dock is now available as a new 3rd generation model. The innovative first-of-kind DHCR is specially designed, engineered and sculpted from solid aluminum to support and silently cool Apple's latest Apple Silicon laptop designs, such as the 2021-2023 MacBook Pro (M2/M1 Pro/Max), 2022-2023 MacBook Air (M2) and future flat-backed Mac laptops, while also working with prior generation Apple laptops.
The DHCR brings best-in-class design to create the ultimate in silent heatsink cooling. The DHCR's heatsink is carved from solid 6061 aluminum to create 12 thin cooling fins with 11 air channels cut to an incredible two inch depth by a narrow 1/4 inch diameter end mill, which provides the heatsink with an exceptionally large 137 square inches of cooling fin surface area for optimal heatsink cooling. The DHCR’s 2.6 pound heatsink is made from continuous material with thin and extra 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 DHCR’s heatsink requires higher precision, longer CNC milling times and much 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 interrupting heat transfer. 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 DHCR not only achieves high levels of heatsink cooling efficiency, but has a design tailor made for optimal performance with the latest generation of Apple laptops, such as the 2021-2023 MacBook Pro. The DHCR’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 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 backside’s lower horizontal air channel creates an open air space below the eleven vertical air channels to generate a passive current of cool air that continuously rises up to cool the twelve vertical cooling fins.
The DHCR’s air channels support silent passive cooling airflow as well as active airflow from the optional Fx Cooling Fan. Angled vertical and horizontal air channels in the DHCR’s heatsink guide cooling airflow through the central hole and front horizontal channel to boost heatsink cooling performance, flush out hot air, and internally cool processors on laptops with a center intake vent, such as the 2021-2023 MacBook Pros (M2/M1 Pro/Max), 2012-2015 MacBook Pros (Intel Retina) and 2010-2017 MacBook Airs (Intel non-Retina). The DHCR Cooling Dock and Fx Cooling Fan utilize a separated fan design instead of using a built-in fan as this allows the fan to generate more airflow with less noise, while also allowing the heatsink to be as large as possible with the most thermal mass and cooling surface area for best heatsink cooling performance.
The DHCR 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 configuration for easy clamshell setup while the laptop remains connected to cables and safely in a padded cradle with adjustable/replaceable laptop support pads. All SVALT cooling systems use modular bolted / snapped cooling system assemblies and ship with the tools required for right-to-repair servicing, exchanging, upgrading and extending product life span. All SVALT products are made locally in the Pacific Northwest with a focus on sustainability, and use solid aluminum for enduring metal construction.
