Air Cool Fan Views
The evaporative cooler was the subject of numerous U.S. patents in the twentieth century; many of these, starting in 1906,[2] suggested or assumed the use of excelsior (wood wool) pads as the elements to bring a large volume of water in contact with moving air to allow evaporation to occur. A typical design, as shown in a 1945 patent, includes a water reservoir (usually with level controlled by a float valve), a pump to circulate water over the excelsior pads and a squirrel-cage fan to draw air through the pads and into the house.[3] This design and this material remain dominant in evaporative coolers in the American Southwest, where they are also used to increase humidity.[4]
Typically, residential and industrial evaporative coolers use direct evaporation and can be described as an enclosed metal or plastic box with vented sides containing a centrifugal fan or 'blower', electric motor with pulleys (known as 'sheaves' in HVAC), (or a direct-driven axial fan), and a water pump to wet the evaporative cooling pads. The units can be mounted on the roof (down draft, or downflow), or exterior walls or windows (side draft, or horizontal flow) of buildings. To cool, the fan draws ambient air through vents on the unit's sides and through the damp pads. Heat in the air evaporates water from the pads which are constantly re-dampened to continue the cooling process. Thus cooled, moist air is then delivered to the building via a vent in the roof or wall.
Back in the prehistoric times (April 2009), we reviewed the Domino A.L.C, an all-in-one liquid CPU-cooling system with three different speeds and an LCD screen. It worked well and was easy to install, but the screen (and attendant fan control) was, in our opinion, poorly thought-out. To see the apparatus, your case needed a side window, and to use it, you’d need to remove your side panel entirely—in which case, why not just use air? But the Domino performed well, so we let it slide.
Like the Corsair H50, the Eco consists of a heat exchanger and pump that mount directly to the CPU socket, a radiator connected to the pump by a closed cooling loop, and a 12cm fan that connects to the radiator. The radiator and fan replace the rear 12cm or 14cm exhaust fan that’s standard in most ATX cases. The pump is powered by a 3-pin connector attached to any motherboard fan header, while the exhaust fan has a 4-pin PWM connector and attaches to the CPU_FAN header—just like with the H50.
