Description

Cryptocurrency mining system for electric vehicles

[0001] The present invention relates to a cryptocurrency mining system, and more specifically, to a system for mining cryptocurrency using an electric vehicle driven by a motor or the like that uses electric energy.

[0002] Cryptocurrency (or crypto money) refers to digital currency or electronic money used in electronic form in a virtual space connected to a network without physical assets such as banknotes or coins.

[0003] Among the terms used in this specification, cryptocurrency is also referred to as virtual currency or crypto currency, but in this specification, it is collectively referred to as cryptocurrency.

[0004] Unlike real-world currencies (coins and banknotes) that are actually traded, cryptocurrencies lack a physical presence in the virtual world. There are many types of cryptocurrencies, the most representative being Bitcoin, first developed in 2008. Other cryptocurrencies that are relatively actively traded include Ripple, Ethereum, and Dogecoin. Cryptocurrencies other than Bitcoin are sometimes referred to as altcoins.

[0005] Credit cards and other simple payments are essentially cash transactions, with the amount deducted from the payment account in the bank account and transferred through an account transfer. However, with cryptocurrency, you can buy and sell items using only cryptocurrency, without cash.

[0006] Cryptocurrency is not a structure in which the issuance and management of currency is done by a centralized organization, but rather a structure in which transactions are made through a distributed database based on P2P (Peer to Peer).

[0007] Cryptocurrencies such as Bitcoin automatically generate a certain amount of Bitcoin at regular intervals according to a set algorithm, and ownership of the generated cryptocurrency can be transferred by solving complex mathematical and cryptographic problems created through a specific algorithm.

[0008] Since the GPU equipped with a graphic card has superior computing power than the CPU equipped with the main mode of a computer in solving complex mathematical and cryptographic problems created through a specific algorithm, cryptocurrency mining is done by graphic cards or multiple hash boards equipped with multiple dedicated ASICs that only perform the calculations necessary for cryptocurrency mining.

[0009] Conventional cryptocurrency mining operations are typically conducted in building structures, commonly referred to as mining farms. However, these fixed cryptocurrency mining systems require additional cooling and ventilation systems to dissipate the large amounts of heat generated in these fixed locations. Furthermore, if effective heat dissipation is not achieved, there is a risk of fire. Furthermore, commercial power must be purchased to operate the mining system.

[0010] The inventor of the present invention proposed a solution to the above problem in the previous Korean Patent Registration No. 2581047, "Vehicle Cryptocurrency Mining System", but intends to propose a new solution for a system for mining cryptocurrency using an electric vehicle that can be driven using electric energy, which has recently appeared.

[0011] The present invention provides a cryptocurrency mining system for an electric vehicle that can mine cryptocurrency by utilizing electricity generated from a rotating wheel or drive axle of an electric vehicle while the vehicle is running.

[0012] As a means for solving the above-mentioned technical problem, the present invention provides a cryptocurrency mining system for an electric vehicle, including a driving battery that stores electric power for driving the electric vehicle, a motor that rotates wheels using the electric power stored in the driving battery, a generator that generates electric power using the rotational force of the wheels, a mining battery that stores electric power generated by the generator, and a mining device that mines cryptocurrency using the electric power stored in the mining battery.

[0013] According to one embodiment, the device may further include a first inverter that converts direct current power of the driving battery into alternating current power for providing the motor, and a second inverter that converts direct current power of the mining battery into alternating current power for providing the mining device.

[0014] In one embodiment, the generator is separated from or coupled to the driving axle of the wheel, and the cryptocurrency mining system for an electric vehicle further includes a control unit that generates a control command to separate or couple the generator to the driving axle based on a rotational speed of the wheel or the driving axle, wherein the control unit can separate the generator from the driving axle when the electric vehicle is not running.

[0015] According to one embodiment, the driving battery and the mining battery may be provided with a rectifier for rectifying the direction of current flow, and a switch for disconnecting the electrical connection according to a control command from the control unit.

[0016] According to one embodiment, when the mining device is started or in operation, if the remaining storage power of the mining battery is below a preset threshold value and the remaining storage power of the driving battery is above a preset lower limit value, the control unit may close the switch so as to charge the mining battery with the power of the driving battery according to a user input or a preset value.

[0017] According to one embodiment, the electric vehicle may include a slot door that is openable and closable on one side, a slot portion that is located on the inside of the slot door and forms a predetermined space, and at least one slot located on the slot portion and connected to the mining device, wherein a graphics card can be mounted or removed.

[0018] According to one embodiment, the control unit can check the power consumption of each of the graphics cards mounted in the plurality of slots, and select and operate the graphics card used by the mining device according to the remaining stored power of the mining battery.

[0019] According to one embodiment, the control unit can check the power consumption of each of the graphics cards mounted in the plurality of slots, and determine a failure for a graphics card whose power consumption is 0.

[0020] According to one embodiment, the slot door further includes a buffer member formed to protrude toward the slot on the inside, and when the slot door is closed, the buffer member can pressurize the graphics card mounted in the slot to prevent separation of the graphics card from the slot.

[0021] According to one embodiment, the device further includes a first temperature sensor for measuring the temperature within the slot portion, a second temperature sensor for measuring the temperature within a mining battery storage space in which the mining battery is accommodated, a first duct for guiding heat generated from the graphics card to the mining battery storage space, and a second duct for guiding air within the mining battery storage space to the slot portion, wherein the control unit may, when the temperature measured by the first temperature sensor is a high temperature equal to or higher than a preset first threshold temperature and the temperature measured by the second temperature sensor is a low temperature equal to or lower than a preset second threshold temperature, guide air within the slot portion to the mining battery storage space through the first duct and guide air within the mining battery storage space to the slot portion through the second duct.

[0022] The cryptocurrency mining system for an electric vehicle according to the present invention can mine cryptocurrency using electricity generated from the rotating wheels or driving axle of the electric vehicle while it is driving.

[0023] Additionally, users can conveniently remove and install the graphics card as needed, and the heat generated from the graphics card during mining can be used to control the vehicle's interior temperature, or conversely, the graphics card can be cooled using the vehicle's interior temperature.

[0037]

[0038] FIG. 1 is a configuration diagram of a cryptocurrency mining system for an electric vehicle according to one embodiment of the present invention.

[0039] As illustrated in FIG. 1, a cryptocurrency mining system for an electric vehicle according to one embodiment of the present invention may include a driving battery (13) that stores power for driving the electric vehicle, a motor (11) that rotates wheels using the power stored in the driving battery (13), a generator (20) that generates power using the rotational force of the wheels, a mining battery (21) that stores power generated by the generator (20), and a mining device (23) that mines cryptocurrency using the power stored in the mining battery (21).

[0040] An electric vehicle does not have an internal combustion engine such as an engine, but drives a motor (11) using electricity stored in a driving battery (13) and rotates wheels (1a, 1b) connected to a driving axle (2) to drive.

[0041] The motor (11) can convert electric energy into kinetic energy to rotate the wheels (1a, 1b), and the reducer (10) is a gear or transmission for efficiently transmitting the power of the motor (11) to the drive shaft (2) or the wheels (1a, 1b), and can obtain high torque by reducing the rotational speed of the motor (11).

[0042] The driving battery (13) is a device that stores electric energy, and the motor (11) can be driven using the power stored in the driving battery (13).

[0043] A first inverter (12) may be provided between the driving battery (13) and the motor (11), and the first inverter (12) may convert the direct current power output from the driving battery (13) into alternating current power for supplying to the motor (11). The first inverter (12) may increase or decrease the driving speed of the motor (11) by adjusting the frequency of the alternating current power supplied to the motor (11) according to a control command from the control unit.

[0044] The driving battery (13) can be controlled for charging and discharging by a battery management system (BMS) within the electric vehicle, and the electric vehicle can further include a voltage conversion device to convert the high voltage power output from the driving battery (13) into a low voltage of 12 V or 24 V, which is the commercial power source for various electrical devices within the electric vehicle.

[0045] In addition, a mining device (23) according to one embodiment of the present invention is a device capable of mining cryptocurrency by performing a computational function, and may be a computing device including at least one graphics card or hash board (collectively referred to as a “graphics card” in this specification).

[0046] In order for the mining device (23) to perform a computational function and solve complex mathematical or cryptographic problems, it must be supplied with power from an external source, and according to one embodiment of the present invention, the driving power of the mining device (23) can utilize the power stored in the mining battery (21).

[0047] The mining battery (21), like the driving battery (13), is a device that stores electric energy, and the mining device (23) can mine cryptocurrency using the electricity stored in the mining battery (21).

[0048] The mining battery (21) and the driving battery (13) can be physically separated from each other, and in this case, the charging method or discharge target, as well as the input / output voltage / current of each, can be different.

[0049] According to a specific embodiment, the driving battery (13) can be charged by receiving power from a commercial power source outside the electric vehicle, but the mining battery (21) can store at least a portion of the power generated by the generator (20) provided on the driving axle (2) to which the wheels (1a, 1b) are coupled.

[0050] That is, the mining device (23) can perform mining work to mine cryptocurrency by receiving power generated from the generator (12) according to the driving of the electric vehicle and using the power stored in the mining battery (21).

[0051] However, since the power supplied to the power supply device (e.g. SMPS; switched mode power supply) of the mining device (23) is usually AC power, and the power output from the mining battery (21) is DC power, a second inverter (22) may be provided between the mining battery (21) and the mining device (23) to convert the DC power output from the mining battery (21) into a sine wave AC power and provide it to the mining device (23).

[0052] At this time, in order to supply stable power to the mining device (23), it is preferable that the control unit of the second inverter (22) output 50 / 60 Hz of 220 V, which is the commercial power of the mining device (23), at a constant level, unlike the first inverter (12).

[0053] As described above, the generator (20) according to one embodiment of the present invention can be coupled to the drive shaft (2) to generate electricity, but according to a preferred embodiment of the present invention, the generator (20) and the drive shaft (2) are not directly connected, but are coupled via a clutch so that the generator (20) and the drive shaft (2) can be coupled or separated from each other according to a control command of the control unit.

[0054] The clutch can be coupled with the drive shaft (2) and the rotor of the generator (20), and the clutch can disconnect the connection between the drive shaft (2) and the generator (20) according to a control command from the control unit.

[0055] Meanwhile, according to one embodiment of the present invention, a cryptocurrency mining system for an electric vehicle including a mining device (23) may include a control unit as a means for controlling the overall operation thereof.

[0056] The control unit can execute various application programs and perform related operations by interfacing with each component of the electric vehicle cryptocurrency mining system, particularly the mining device (23), the second inverter (22), and the clutch. In other words, the control unit can perform cryptocurrency mining operations using the electric vehicle by processing signals or data input / output through the components of the electric vehicle cryptocurrency mining system or by executing application programs stored in the storage unit.

[0057] That is, the control unit can mine cryptocurrency by operating the mining device (23) according to a series of operation processes consisting of user input through an interface device or a predetermined step stored in a storage unit.

[0058] In addition, as described above, the control unit can generate a control command to disconnect the connection between the drive shaft (2) and the generator (20), and transmit the control command generated in this way to the clutch so that the drive shaft (2) and the generator (20) can be coupled or separated from each other through the clutch.

[0059] However, since the generator (20) according to one embodiment of the present invention can be coupled to the driving shaft (2), when the driving shaft (2) starts to rotate, the rotor of the generator (20) may interfere with the rotational motion of the driving shaft (2) due to inertia. This may ultimately affect the battery consumption of the driving battery (13), and therefore, it is preferable that the generator (20) according to one embodiment of the present invention be coupled to and detachable from the driving shaft (2).

[0060] Accordingly, the control unit can measure or confirm the current speed of the electric vehicle, or the current rotation speed of the wheels (1a, 1b) or the drive shaft (2), and when the electric vehicle, wheels (1a, 1b) or the drive shaft (2) is at a standstill or changes from a standstill to a moving state, it is preferable to separate the generator (20) from the drive shaft (2).

[0061] When an electric vehicle is in motion and the electric vehicle, wheels (1a, 1b) or drive axle (2) are moving at a predetermined speed or higher, the control unit can couple the generator (20) to the drive axle (2).

[0062] As a specific example, the control unit can measure or receive the current speed of the electric vehicle, and when the current speed is 0 or lower than a preset operating reference speed according to the current speed of the electric vehicle, the control unit can separate the generator (20) from the driving shaft (2) using a clutch, and when the current speed of the running electric vehicle exceeds the operating reference speed, the control unit can connect the generator (20) to the driving shaft (2) using a clutch.

[0063] In this way, by controlling the generator (20) and the driving axle (2) according to the control command of the control unit, the power consumption of the driving battery (13) can be minimized.

[0064] Of course, the generator (20) coupled to the driving axle (2) can generate power and store it in the mining battery (21), and after a certain level or more of power is stored in the mining battery (21), even if the electric vehicle is not running, the mining device (23) can perform cryptocurrency mining operations using the power stored in the mining battery (21).

[0065] Meanwhile, FIG. 2 is a connection diagram between a mining battery and a driving battery of a cryptocurrency mining system for an electric vehicle according to one embodiment of the present invention.

[0066] As shown in Fig. 2, a mining battery (21) according to one embodiment of the present invention can be electrically connected to a driving battery (13), and a control unit can charge the mining battery (21) by applying power stored in the driving battery (13) to the mining battery (21) by controlling the operation of a switch (32).

[0067] To this end, a rectifier (31) may be included between the mining battery (21) and the driving battery (13) so that current can flow only in one direction from the driving battery (13) to the mining battery (21), and in addition, a switch (32) may be provided between the mining battery (21) and the driving battery (13) so as to be able to interrupt the electrical connection according to a control command from the control unit.

[0068] In order to charge the stored power of the driving battery (13) to the mining battery (21), a power conversion element (not shown) for converting input / output voltage and / or current may be provided on the connecting line between the driving battery (13) and the mining battery (21), and when charging the mining battery (21) using the power stored in the driving battery (13), a battery charge / discharge control device (not shown) for controlling the charge / discharge state may be provided.

[0069] Hereinafter, a process of charging a mining battery (21) by applying power stored in a driving battery (13) according to one embodiment of the present invention will be examined.

[0070] FIG. 3 is a step-by-step flowchart of the operation process between a mining battery and a driving battery of a cryptocurrency mining system for an electric vehicle according to one embodiment of the present invention.

[0071] As illustrated in FIG. 3, a control unit according to one embodiment of the present invention can check (S2) whether power is generated from a generator (20) when the mining device (23) is started or in operation (S1).

[0072] At this time, if the generator (20) does not operate normally and does not generate power, but is in an abnormal state in which power is not generated by the generator (20) or the amount of power generated (or the amount of power per hour) does not reach a preset lower limit, if the remaining stored power of the mining battery (21) is below a preset threshold value (S3) and the remaining stored power of the driving battery (13) is above a preset lower limit value (S4), the mining battery (21) can be charged with the power of the driving battery (13).

[0073] That is, when the generator (20) is not operating normally, the power stored in the driving battery (13) is higher than the lower limit for minimum driving or normal driving (S4), but the power stored in the mining battery (21) is lower than the threshold value (S3), making it difficult to operate the mining device (23) normally, the power stored in the driving battery (13) can be used to charge the mining battery (21).

[0074] In order to charge the power stored in the driving battery (13) to the mining battery (21), the switch (32) provided between the driving battery (13) and the mining battery (21) can be closed, and if necessary, the battery charge / discharge control device can be used to control the battery charge / discharge between the driving battery (13) and the mining battery (21), thereby charging the power stored in the driving battery (13) by applying it to the mining battery (21).

[0075] If the generator (20) is not operating normally, but the remaining stored power of the mining battery (21) exceeds a preset threshold, the control unit can use the remaining power of the mining battery (21) to enable the mining device (23) to safely perform a shutdown operation (S32). However, the control unit can enter a forced mode (S31) by a user input or the like, and when entering the forced mode, the control unit can use the remaining power of the mining battery (21) to enable the mining device (23) to continue cryptocurrency mining operation without shutting down the mining device (23) (S1).

[0076] Meanwhile, FIG. 4 is a drawing showing a slot section of a cryptocurrency mining system for an electric vehicle according to one embodiment of the present invention.

[0077] As illustrated in FIG. 4, a cryptocurrency mining system for an electric vehicle according to one embodiment of the present invention may include a slot door (41) that is provided to be openable and closable on one outer surface of the electric vehicle.

[0078] A slot door (41) exposed on the outer surface of an electric vehicle can open and close a slot portion (40), which is a predetermined space inside. Accordingly, when the slot door (41) is opened, the slot portion (40) can be exposed to the outside, and conversely, when the slot door (41) is closed, the slot portion (40) may not be exposed to the outside.

[0079] A slot portion (40) having a predetermined space may be provided on the inside of the slot door (41), and the slot portion (40) may include at least one slot (S1 to S4) (43) in which a graphic card can be mounted and removed, so that a user can conveniently insert and mount a graphic card in the slot (43) by opening the slot door (41).

[0080] The slot (43) provided in the slot section (40) is electrically connected to the mining device (23), so that the mining device (23) can check whether a graphics card is mounted in the slot (43) using a plug-and-play function, etc., and can also perform cryptocurrency mining using the graphics card mounted in the slot (43).

[0081] At this time, the present invention is not particularly limited, but it is preferable that there are multiple slots (43) in the slot section (40), and when at least one graphics card is mounted in multiple slots (43) by the user, the mining device (23) can perform cryptocurrency mining operations using the graphics card.

[0082] In this way, since the slot portion (40) provided with the slot (43) according to one embodiment of the present invention is provided adjacent to the outer side of the electric vehicle, similar to a charging terminal for charging a driving battery (13) in an electric vehicle, it is desirable to allow heat generated from the graphics card due to cryptocurrency mining operation to be easily cooled.

[0083] However, since the slot (43) is provided in a running electric vehicle, the graphics card mounted in the slot (43) may be separated from the slot (43) due to vibration or impact as the electric vehicle runs.

[0084] Therefore, in order to solve this problem, the slot door (41) according to one embodiment of the present invention may include a buffer member (45) formed to protrude toward the slot (43) on the inner surface, more specifically, the graphics card mounted in the slot (43).

[0085] The buffer member (45) is an elastic member formed to a predetermined height. When the slot door (41) is closed, the buffer member (45) pressurizes the graphic card mounted in the slot (43), thereby preventing the graphic card from being separated from the slot (43) even when vibration or shock occurs while the electric vehicle is running.

[0086] That is, the slot portion (40) formed within the slot door (41) may be a space of a predetermined size provided so that a graphic card can be mounted in at least one of the internal slots (43), and it is preferable that when the slot door (41) is closed, the antistatic sheet provided on the inner surface of the slot door (41) presses the graphic card mounted in the slot (43) toward the slot (43).

[0087] The buffer member (45) is made of a material that is elastic at least in the thickness direction, and when the slot door (41) is closed, the buffer member (45) can pressurize the graphic card having electronic components and come into contact with the graphic card. Therefore, the buffer member (45) according to a preferred embodiment is preferably an antistatic sheet so as not to generate static electricity and prevent leakage current from the graphic card from being applied.

[0088] The anti-static sheet is a material that does not transmit electricity, and can prevent the generation of electricity, i.e., electric charges, on the substrate of the graphic card, thereby preventing the graphic card in the slot (40) from being electrically shocked.

[0089] The unexplained drawing symbol 42 of FIG. 4 may indicate a hinge axis provided so that the slot door (41) can be opened and closed, and it is preferable that the slot portion (40) in which the graphic card is mounted is provided adjacent to the outer surface of the electric vehicle so that the graphic card in a heated state can be easily cooled.

[0090] Meanwhile, FIG. 5 is a step-by-step flowchart of a process for operating a graphics card according to priority in a cryptocurrency mining system for an electric vehicle according to one embodiment of the present invention.

[0091] As illustrated in FIG. 5, a slot unit (40) according to one embodiment of the present invention may be provided with a plurality of slots (43), and when a graphic card is mounted in at least some of the plurality of slots (43) by a user, the control unit may check the power consumption (or power consumption amount) of each graphic card mounted in the plurality of slots (43) (S10).

[0092] At this time, the control unit checks the power consumption of each graphic card mounted in a plurality of slots (43), compares it with the remaining storage power of the mining battery (21) (S30), and then, depending on the remaining storage power of the mining battery (21), the mining device (23) can selectively operate at least some of the graphic cards used during cryptocurrency mining operation (S41~S42).

[0093] According to a specific embodiment, the control unit can check the power consumption of the entire currently mounted graphic cards (S10), and then compare it with the remaining storage power of the current mining battery (21) (S30), and if the remaining storage power of the mining battery (21) is less than the power consumption of the entire graphic cards, a graphic card with lower power consumption among the graphic cards can be given priority and selected (S41).

[0094] That is, the stored power of the mining battery (21) can be charged by the operation of the generator (20) or charged with the power stored in the driving battery (13) in the forced mode, and when the mining battery (21) is not fully charged, one or more graphics cards with lower power consumption can be preferentially selected in order of the remaining stored power of the current mining battery (21) and the selected graphics card can be operated preferentially. Of course, here, it is preferable that the sum of the power consumption of at least one graphics card selected preferentially is lower than the remaining stored power of the current mining battery (21), and as the charge level of the mining battery (21) gradually increases, at least some of the remaining graphics cards, which are currently not in operation, can be selectively operated by giving priority to those with lower power consumption.

[0095] Conversely, the remaining storage power of the current mining battery (21) may be greater than the sum of the power consumption of all currently installed graphic cards, and in this case, the control unit may use all graphic cards to allow the mining device (23) to perform cryptocurrency mining operations.

[0096] Meanwhile, a control unit according to one embodiment of the present invention can check the power consumption of the graphics card for each slot (43) of the slot unit (40) (S10) and store the value in the storage unit.

[0097] Since the mounting and removal of the graphic card in the slot (43) of the slot section (40) may not occur frequently, it is possible to check (S20) whether there is a change in the mounting status of the graphic card in the slot (43) using the plug-and-play function, and if there is no change in the mounting status of the graphic card, the power consumption of the graphic card for each slot stored in the existing storage section is compared with the remaining storage power of the mining battery (21) (S30), and at least some of the multiple graphic cards can be selectively operated (S41).

[0098] In this case, when the control unit uses the power consumption value of the graphics card for each slot stored in the storage unit, there is no need to frequently check the power consumption of the graphics card for each slot at regular intervals (or in real time).

[0099] Of course, if there is a change in the mounting status of the graphic card in the slot (43), the power consumption of the graphic card in each slot (43) of the lot (40) can be re-checked (S10) and the value can be updated and stored in the storage unit.

[0100] Meanwhile, FIG. 6 is a step-by-step flowchart of a process for determining a failure of a graphics card of a cryptocurrency mining system for an electric vehicle according to one embodiment of the present invention.

[0101] As illustrated in FIG. 6, a control unit according to one embodiment of the present invention can check power consumption of each graphic card mounted in a plurality of slots (43) of a slot unit (40) (S110), and in the process of checking power consumption of each graphic card (S110), if the power consumption is 0 (S120), a failure of the corresponding graphic card can be determined (S130).

[0102] Accordingly, even if a graphics card is mounted in at least one of the plurality of slots (43) of the slot unit (40), if the power consumption of the graphics card is 0, the control unit can determine that the graphics card is faulty, and can notify the user of the determination result in a visual or auditory form through an alarm device or an external terminal, and the control unit can prevent the mining device (23) from performing a cryptocurrency mining operation or repeating a mining operation attempt using the faulty graphics card.

[0103] Meanwhile, as described above, when at least one graphic card is mounted in the slot (40) and the mining device (23) mines cryptocurrency using the graphic card mounted in the slot (40), the ambient temperature of the slot (40) or the graphic card may rise due to heat generation from the graphic card, and a graphic card in a high temperature state may not only reduce the cryptocurrency mining effect but also shorten the lifespan of the graphic card.

[0104] To address these issues, a temperature sensor (44) may be provided within the slot (40) to measure the temperature surrounding the graphics card mounted in the slot (43) (see Fig. 4). Furthermore, as described below, a temperature sensor (not shown) may be provided within the storage space (3) housing the mining battery (21) to measure the temperature.

[0105] The control unit can use the temperature value measured by the temperature sensor (44) provided in the slot unit (40) to induce the high temperature air in the slot unit (40) to the mining battery (21) through the duct when the temperature value is higher than the preset threshold temperature.

[0106] Since the charging capacity of the mining battery (21) decreases and the charging speed slows down at low temperatures, especially in winter, the charging efficiency is low, so when a high temperature atmosphere is formed in the slot (40) due to the operation of the graphics card, it is desirable to increase the charging efficiency of the mining battery (21) by applying the high temperature air in the slot (40) to the mining battery (21), specifically, to the storage space (3) containing the mining battery (21) inside.

[0107] FIG. 7 is a duct connection diagram between a slot portion and a storage space for a mining battery of an electric vehicle cryptocurrency mining system according to one embodiment of the present invention.

[0108] As shown in Fig. 7, a duct may be provided as a passage through which air can flow between the slot portion (40) and the storage space (3) in which the mining battery (21) is accommodated. In this case, according to a preferred embodiment, the duct may be a plurality of first ducts (5a, 5b) and second ducts (6a, 6b).

[0109] Accordingly, when the temperature within the slot portion (40) is higher than the preset first critical temperature and the temperature within the storage space (3) is lower than the preset second critical temperature, the control unit can guide the high-temperature air within the slot portion (40) to the mining battery (21) through the first duct (5a, 5b), and in conjunction therewith, guide the low-temperature air within the storage space (3) to the slot portion (40) through the second duct (6a, 6b). Of course, here, the first critical temperature and the second critical temperature are different from each other, but the first critical temperature may be higher than the second critical temperature.

[0110] Here, the present invention is not particularly limited, but in this specification, for easy explanation of the present invention, the first duct (5a, 5b) may refer to a passage through which air flows from the slot portion (40) to the storage space (3) containing the mining battery (21), and the second duct (6a, 6b) may refer to a passage through which air flows from the storage space (3) containing the mining battery (21) to the slot portion (40).

[0111] According to a preferred embodiment of the present invention, it is preferable that high temperature air in the slot portion (40) is guided to the storage space (3) along the first duct (5a, 5b), and low temperature air in the storage space (3) is guided back to the slot portion (40) along the second duct (6a, 6b), so that the air circulates.

[0112] The airflow control device (4) is a device provided on the first duct (5a, 5b) and the second duct (6a, 6b) so that air can flow smoothly along the first duct (5a, 5b) and along the second duct (6a, 6b), and may include at least one opening / closing device that operates to open / close the flow of the first duct (5a, 5b) and / or the second duct (6a, 6b) according to a control command from a control unit, and may also include at least one fan that operates to force the flow of the first duct (5a, 5b) and / or the second duct (6a, 6b) according to a control command from the control unit.

[0113] Ultimately, the high temperature air in the slot (40) can be supplied to the mining battery (21) in the storage space (3) to increase the charging efficiency of the battery, and in conjunction with this, the low temperature air (especially in winter) in the storage space (3) can be supplied to the slot (40) to cool the graphics card that generates heat, thereby preventing a decline in the performance of the graphics card.
