Two loops through one radiator

According to Alphacool, its Dual-Flow radiators were developed specifically for use in servers. It calls the ability to run two separate loops through one radiator unique. In a single loop there are also advantages to using them, as you can split the cooling surface and use it directly behind hotspots.

What does dual flow mean?

The water flow in a classic radiator is in a U-shape: water is introduced on one side and runs once through half of the radiator before turning around. Running back through the other half, it reaches an outlet that is on the same side as the inlet. In an X-Flow radiator the water flows once from left to right completely through the radiator, so the inlet and outlet are on opposite sides. With the Dual-Flow Radiator the water flows from one side to the other just like the X-Flow. However, this one is divided in the middle. You could also say it is nothing more than two small X-Flow Radiators in one.

What are the advantages?

Space is extremely limited in most server racks, and being able to do fancy loops is not usually an option. Due to this you can utilize the radiator to simplify the loop and reduce the amount of tubing needed. Alphacool reports that in some test scenarios it has even seen an increase in performance from the loop due to this method too.

What the loop needs

Each input and output in use takes one of our fittings, and the 8 screw plugs in the box close the other connections. The radiator takes three 120 mm fans. The box also holds 12 screws each in M3x8, M3x30 and M3x45 and a hexagon socket.

We also have the next thickness up in this design, the NexXxoS UT60 Full Copper Dual-Flow 360mm Radiator.
