Abstract: An immersion cooling system includes a pressure seal tank, an electronic apparatus, a pressure balance pipe and a relief valve. The pressure seal tank is configured to store coolant. A vapor space is formed in the pressure seal tank above the liquid level of the coolant. The electronic apparatus is completely immersed in the coolant. The pressure balance pipe has a gas collection length. The first port of the pressure balance pipe is disposed on the top surface of the pressure seal tank. The relief valve is disposed on the second port of the pressure balance pipe. The second port is farther away from the top surface of the pressure seal tank than the first port. The gas collection length of the pressure equalization tube allows the concentration of vaporized coolant at the first port to be greater than the concentration of vaporized coolant at the second port.
