Liquid-immersion cooling device

A liquid-immersion cooling device comprising:

• a reservoir configured to contain coolant to immerse a plurality of electronic devices;
• at least one partition board;
• and at least one heat exchanger;
• wherein:
• the at least one partition board and the at least one heat exchanger are mounted within the reservoir;
• the at least one partition board is arranged parallel to the plurality of electronic devices;
• the at least one heat exchanger and the plurality of electronic devices are respectively arranged on opposite sides of the at least one partition board within the reservoir;
• the at least one partition board is configured to guide a flow of the coolant within the reservoir;
• when the coolant flows through the plurality of electronic devices and carries away heat generated by the plurality of electronic devices, the coolant is guided by the at least one partition board to flow through the at least one heat exchanger;
• after exchanging heat with the at least one heat exchanger, the coolant is guided by the at least one partition board to flow through the plurality of electronic devices;
• wherein:
• the at least one heat exchanger comprises a inflow port and an outflow port;
• the inflow port and the outflow port couple the at least one heat exchanger to an external supply device located outside of the reservoir;
• and further comprising at least two partition boards and at least two heat exchangers, wherein:
• the at least two partition boards are arranged parallel to each other;
• the plurality of electronic devices are arranged between the at least two partition boards;
• the at least two heat exchangers are respectively arranged on a side of the at least two partition boards facing away from the plurality of electronic devices.
