The tank body holds a coolant and an electronic device. The tank body defines an inlet and an outlet. The inlet and the outlet are respectively located at opposite ends of the electronic device for inputting and outputting the coolant. The coolant flows through the electronic device. The liquid flow tube includes at least one adjuster. The liquid flow tube is located inside the tank body and coupled to at least one of the inlet or the outlet. The at least one adjuster faces the electronic device for controlling an amount of the coolant flowing in or out of the tank body. ## Claims ### Claim 1 An immersion cooling tank comprising: a tank body configured to hold a coolant and an electronic device, the tank body defining an inlet and an outlet, the inlet and the outlet respectively located at opposite ends of the electronic device and being configured for inputting and outputting the coolant, a flow passage being formed for the coolant to circulate through the electronic device;
