SVALT Cooling Dock model DHCR 4th generation with new and updated noted cooling features New 4th Gen Cooling Features
The new 4th generation DHCR includes extensive improvements for a substantial increase in cooling efficiency with the latest Apple MacBook Pro and Air laptops, along with comprehensive optimization for the 2021+ MacBook Pro. The new and improved 4th gen DHCR cooling features are grouped into the following three categories as shown in the diagram above and described below: (1) conductive cooling, (2) heatsink cooling and (3) airflow cooling.

  • (1) Improved conductive cooling with increased heat transfer from flat-backed laptops like the 2021+ MacBook Pro and 2022+ MacBook Air. This is accomplished with a 6% larger thermally conductive interface for increased surface area, up to 68% thinner laptop coupling plate for increased heat distribution, and available for the first time with the 4th gen, direct metal-to-metal laptop coupling for reduced impedance and unrestricted conductive heat transfer.

  • (2) Improved heatsink cooling with increased heat transfer from heatsink to passive/active cooling airflows. This is accomplished with up to 185% deeper and 18% taller cooling fin air channels, up to 52% increased surface area, and up to 846% more continuous and interconnected cooling fin air channels for increased heat flow throughout the heatsink.

  • (3) Improved airflow cooling with increased airflow into the 2021+ MacBook Pro’s center air intake vent for direct internal processor cooling, as well as flushing out more hot air away from laptop exhaust vents. This is accomplished with 7x more through-hole openings, a 91% increase in total through-hole open area, and 151% increase in opening width. Available for the first time with the 4th gen, the through-holes become air channels that extend below the laptop’s bottom edge with a position and angle to guide cooling airflow into the 2021+ MacBook Pro’s center intake. A 22% smaller front horizontal air channel with 80% deeper curving sides concentrates cooling airflow along the laptop’s bottom edge vents.

SVALT Cooling Dock model DHCR 4th generation Fx Cooling Fan diagram Active Airflow Cooling Features
The Fx Cooling Fan accessory adds a boost of active airflow cooling to heatsink Cooling Dock DHCR, DHC and DH models. Compared to a built-in fan design, the separate Fx Cooling Fan design allows for more efficient airflow through the fan as well as through the heatsink, which results in moving more cooling air with less noise. The separate fan design also allows the heatsink to be as large as possible with the maximum thermal mass and cooling surface area for improved heatsink cooling performance.

The Fx accelerates DHCR cooling through the following methods:
  • Cooling the heatsink by driving airflow through cooling fin air channels.
  • Flushing out hot air from the laptop’s exhaust vents by driving airflow through numerous through-holes and then the front horizontal air channel.
  • Internally cooling laptop processors by driving air into a compatible laptop’s center intake vent, such as with the 2021+ MacBook Pro, 2012-2015 MacBook Pro (Intel Retina) and 2010-2017 MacBook Air (Intel non-Retina).

The 4th generation DHCR includes the following revisions to improve active airflow cooling with the Fx:
  • Increased heatsink surface area for improved heat transfer from heatsink to active cooling airflows.
  • Increased through-hole open area for more direct internal processor cooling through the laptop’s center intake vent and for flushing out more hot air from the laptop’s exhaust vents.
  • Increased concentration of airflow along the bottom screen-hinge edge of laptop for more direct internal processor cooling and flushing out more hot air.
  • Increased guided airflow towards laptop intake vent for more direct internal processor cooling.



SVALT Cooling Dock model DHCR 4th generation laptop compatibility diagram Laptop Compatibility Features
The DHCR has been specially designed, engineered and sculpted from solid aluminum to support and silently cool Apple's latest Apple Silicon laptop designs, such as the 2021+ MacBook Pro and 2022+ MacBook Air, while also working with all current and prior generation Apple laptops of the last decade.
  • Edge protection pads located around all four sides of the laptop coupling plate protect the laptop from edge and corner impacts during setup.
  • Leaning support for compatibility with a wide range of laptops, tablets and other devices.
  • Angled lower support shelf and non-slip padding for holding device in place.

  • The heatsink’s laptop coupling plate has rounded edges and corners to reduce scratching potential during setup with the direct metal-to-metal configuration.
  • More numerous through-holes spread over a wider area to match the 2021+ MacBook Pro center intake vent width for more direct internal processor cooling.
  • Smaller front horizontal air channel to concentrate cooling airflows along the 2021+ MacBook Pro bottom edge for more direct internal processor cooling and flushing out more hot air.
  • New air channels extend below the 2021+ MacBook Pro center intake vent for more direct internal processor cooling.
  • Up to a 227% increase in 2021+ MacBook Pro cooling surface area.
