Akasa are an old hand when it comes to CPU cooling. With a large range of coolers on the market and a reputation for cheap, quiet and efficient coolers they are quite often first choice for those wanting quiet computing at a good price point.
Today we're taking a look at the Akasa Revo Thermaldynamic Cooler from Akasa. With a press release mentioning the terms "CPU Cooler" and "bubble pump" we just had to take a look.
The Technology - in brief
Rather than just re-hash Akasa's press release I'll give you my own thoughts on what Akasa have said about their cooler.
Basically the cooler has a liquid coolant that runs from a small chamber in the case of the cooler next to the CPU cooler and up into a small reservoir at one side of the radiator. This then goes through an "up-pipe" as Akasa put it (heat pipe) and into the radiator. Akasa then say that the "specially designed dual-component liquid-coolant acts as a bubble-pump" and forces heat along the radiator. Hmm, well to me that sounds like the heat moves through the radiator by convection, aided by heat bubbles in the system. At this point the radiator and fan cool the liquid through heat dissipation on a large surface area (just like a water-cooling rad) and the cold air travels through the "down pipe" back into the reservoir.

Now most heatpipe coolers have an array of anything from 2 to 8 heatpipes to cool down todays egg-fryers, but the Revo only has one, interesting.
Additional Answer from Akasa
Akasa have said that the Bubble pump technology is a lot more like a water cooling loop than a heatpipe cool. With the Radiator on the cooler I am in partial agreement. However, as you will see later Akasa have yet to achieve the results that watercooling gets.
The packaging for the Revo is pretty attractive and shows a pretty industrial looking heatsink on the front with a nice blue Akasa fan on it. Plenty of information abounds on the box so you're good to go there.
The package with the cooler is a standard affair, albeit a little more tough looking than most.
