The new Canaan miner is cooled natively by liquid immersion, which promises better performance.
Canaan, one of the first manufacturers of Bitcoin ASIC miners (BTC), launched the Avalon Immersion Cooling Miner A1066I, a device designed to be cooled by liquid.
Unlike traditional air-cooled devices and common types of liquid cooling for computer enthusiasts, the electrical components of the A1066I are immersed in a special dielectric fluid that removes heat directly from the computer plates.
The dielectric fluids are specially designed to insulate the components and prevent corrosion and short circuit damage that would occur with standard water or other types of fluids. They are also different from water block based liquid cooling, where a special heat exchanger isolates the water from the components.
The A1066I is a large containment device that can hold up to 90 immersion-cooled units. Canaan says that each unit produces 50 TH/s for an electrical consumption of 3400 watts, while each tank reaches up to 7200 TH/s and 306 kilowatts of electrical consumption when completely filled.
While Canaan says the A1066I performs better than its top-of-the-line air-cooled A1246, the latter has 90 TH/s of mining power and consumes the same amount of energy, making it more efficient on paper. Cointelegraph requested clarification on the figures but did not receive an immediate response.
However, the native liquid cooling feature may make the device more attractive to certain classes of miners, especially those operating in warmer regions. The more efficient cooling method also allows for more aggressive overclocking, potentially allowing for higher hash performance, although power consumption remains a major constraint when it comes to increasing the hash rate. The cooling method also benefits protection against dust and overheating.
Canaan is one of the original manufacturers of ASIC equipment and the first to launch a successful initial public offering on NASDAQ. Its performance has been mediocre since then, as claims and statements have surfaced that the company misled investors. Quarterly operating losses also weighed heavily on the share price.
Canaan’s main competitors are Bitmain, which is also having its share of problems, and MicroBT, a rising manufacturer that has steadily gained market share in recent months.
