The S17+ mining machine is an integrated design of chassis power supply. Its bare metal size is 340×178×304.3mm. It can be placed horizontally or vertically according to the height space of the mine shelf; the mass is 11.3kg. The heat dissipation of the mining machine is designed with front and rear double-tube fans, and the outer surface of the fan is equipped with a mesh cover, which ensures that the mine operation and maintenance personnel avoid injury caused by accidental contact with the blades, and protects the safety of the operation and maintenance personnel; there is a grille on the back of the fan, which effectively prevents the External particles enter the high-speed rotating fan and hit the hash board. The voltage of a single fan is 12V, the current is 2.7A, the maximum speed is 6000rpm, and the maximum air volume is 195cfm. According to the change of the series-parallel characteristics of the fans, the parallel fan design on one side of the miner significantly increases the ventilation volume; the series design of the fans on both sides of the miner significantly enhances the resistance of the miner to environmental resistance, that is, the ventilation volume of the miner does not increase with the mine. The changes in the field environment fluctuated violently. A large number of heat sinks are laid on the internal hash board of the mining machine, and the area of a single heat sink gradually increases from the air inlet to the air outlet. This design loads heat transfer away, effectively transferring the heat generated by the chip to the air.
