Arctic Active Cooling DC Condensing Unit is directly in contact with the user’s evaporator or a cold plate. In fact, with no secondary coolant needed, the system only requires minimal parts. There is no necessary to circulate cool air or to circulate coolant with fans or pumps. Because these additional parts add complexity and inefficiency. The DC condensing unit’s major advantage is to get rid of most ductwork and piping, and their ease of integration into the user’s equipment.

 

The DC Condensing Unit is also named the direct expansion system. It typically offers the highest heat transfer rates. It is an ultra-compact chiller by assembling with a mini dc compressor. The direct expansion system use R134a or R290 refrigerant. And the mini compressor drives the refrigerant directly through the evaporator, so that the refrigerant absorbs heat directly at the heat source, minimizing the size and component count of the system.

 

This concept eliminates the need for a water cooling loop (water pump, reservoir, and associated tubing) resulting in a greatly simplified cooling system. Arctic Active Cooling dc condensing unit is the world’s smallest air direct cooling system, and it can integrate directly into a customer’s compact systems and provide very high heat fluxes at the heat source.
