Now you need to remove the baffle located at the front side of the control board. You must also remove the connecting wire of the control board. You can pull and remove the control board easily from the machine now. The Antminer T19 88T Bitcoin miner machine makes use of a new design in the control board. The model of the control board is Ctrl_C55, and the version of the board is V2.2010.

Disassembling the Power supply of the Antminer T19 88T Bitcoin miner machine

You can see a new APW12 power supply module in the Antminer T19 88T Bitcoin miner machine. This power supply model comes with an adjustable voltage feature. You can vary the voltage from 12 V to 15 V. It takes two external AC lines to generate this voltage. You will be able to see the manufacturer’s identification label on the power supply unit. There is also a warning label that indicates a power failure. You need to ensure that both the power cables of the unit need to be disconnected at the same time.

There are three fans inside the APW12 power supply unit of the miner machine. These three fans help to remove the heat from the power supply, thereby protecting the internal electronic components. The fact that this miner makes use of two power supply cables helps to protect the power socket and the cables from getting overheated. In addition, it provides over-temperature, under-voltage, and over-current protection. Thus, it helps to enhance the overall reliability of the power supply unit.

The chassis of the Antminer T19 88T Bitcoin miner machine is made of aluminum alloy. It is prepared using the die-casting method. You can see slots for the hash board and control board in the chassis. There is also a connection gap between the power supply and the hash board.

Antminer T19 2

There are 3 hash boards in the Antminer T19 88T Bitcoin miner machine. You can see heat sinks on either side of these hash boards. The heat sink design in these hash boards is the same as the ones used in the Antminer S19 Pro 110T miner machines.

You will be able to see two heat sinks on the surface of the ASIC chip. It is provided to remove the heat from the chip. These heatsinks are designed in a streamlined fashion. It helps to reduce the wind resistance on the air inlet side. In addition, it provides an efficient method of circulation of the air inside the machine. Thus, the heat is removed from the system quickly without any dust accumulation.

You will be able to find one heat sink on the other side. If you move from the air inlet side towards the back, you can notice that the size of the heat sink is increasing gradually. This design helps to provide uniform heat dissipation for the complete hash board.

There are 76 ASIC chips on each hash board of the Antminer T19 88T Bitcoin miner machine. There are 3 hash boards in each miner machine. So, there are 228 ASIC chips on Antminer T19 88T Bitcoin miner machine. These are 7nm TSMC chips. They contain the SHA256 algorithm. The model number of the ASIC chip is BM1398.
