We believe that the cost-effective advantage of Antminer S9J is obvious, and its current market status and evaluation are underestimated. At present, the evaluation of the AntMiner S9J obtained on the market is that the AntMiner S9J is an upgraded version of the Antminer S9I and AntMiner S9. According to the long-term market response, the S9J has basically inherited and continued the previous generation in the aspect The design of the classic mining machine is not very different. The upgraded version of all miners is eventually reflected in low power consumption and high calculation power. Compared with Antminer S9I, Antminer S9J can be used as a version upgrade. Choose, there is an improvement in computing power.
Antminer S9J’s appearance
In terms of appearance, the Antminer S9J is not very different from the previous Antminer S9 series mining machines. The alloy shell and the side of the chassis retain the unique guide of the ant mining machine to improve the compact and firmness of the machine. The appearance size of the Antminer S9J is 345mm (L)*125mm (W)*155mm (H).
Although the design of the chassis is not the most important, compared to the difficulty and complexity of the upgrade chip, the design of the appearance is easy to distinguish from other mining machines, that is, a good mining machine is not only a good mining machine not only It is a breakthrough in computing power and power consumption, and the appearance will also be more conducive to the reasonable use of the space in the space.
The computing power board of Antminer S9j
After disassembling the air outlet fan of the Antminer S9J, it can be seen that the position of the three computing power boards is fixed by the internal card slot. After taking it out of the computing power board alone, you can see that each piece is calculated. The force plate carries 63 chips, and the surface of the line board is distributed with a piece of the heat sink, which is distributed on the two planes of the chip.
From the picture, it can be found that the level of the ups and downs of the chip and heat sink is different from the position of the upward discharge of the line board and the front and back of the heat sink. The height and thickness are different, and the design is obviously specially treated with special alienation.
In addition, at the air inlet, the layout of the heat sink shows a vacancy. This layout is to make the winding wind to the greatest extent to the computing power board space, especially input to the near behind the outlet. Chip part.
In fact, whether it is the number of heat sinks, materials, thickness, height, layout changes, or special design, the root cause of this design is to allow the wind and cold heat dissipation system to play the maximum heat dissipation effect.
Antminer S9J’s cooling fan
There are two heat dissipation fans in the front and after the Antminer S9J miner. You can only see the cooling fan of the yellow label surface of the air outlet directly from the appearance. The rated voltage is 12V and the rated current is 2.3A. 2.7A.
The speed of the fan will be automatically adjusted with the temperature of this mining machine. After the wind speed measurement at the stable runtime, the wind speed of the air inlet reaches 4.5m/s, and the wind speed of the outlet reaches 9m/s.
Fan design with different speeds can be combined with the temperature of the mining machine. The temperature on the side surface of the mining machine box at a stable runtime is about 43 ° C, the air inlet temperature is 40 ° C, and the temperature of the calculation board interface is about 48 ° C. The maximum measurement data of the air temperature of the air outlet has reached 62.5 ° C. Since the outlet needs to bear the main heat diffusion task, of course, there is a greater air output.
