The patent US12075599B2 describes an electronic apparatus featuring an immersion cooling system designed to manage heat generated by at least one component. The system includes a main tank that serves as a single compartment for a heat dissipation medium, where the heat-generating component is immersed. An auxiliary tank is positioned adjacent to the main tank and is part of a liquid amount adjusting module that includes a liquid level sensor, a pipeline, and a pump. The design ensures that the heat dissipation medium flows unidirectionally from the main tank to the auxiliary tank through a specific pathway, allowing for effective temperature regulation. The pump, located in the auxiliary tank, facilitates the return of the medium to the main tank, maintaining optimal liquid levels.

Additional features of the immersion cooling system include a condensation structure above the main tank, which allows vaporized heat dissipation medium to condense and return to the main tank by gravity. The auxiliary tank's capacity is designed to be smaller than that of the main tank, ensuring efficient operation. The system may also incorporate a guide rail for pump movement, a filter for medium purification, and a pressure gauge for monitoring. The claims emphasize the innovative design of the liquid level adjusting module, which is integral to the overall functionality of the cooling system, ensuring that the heat dissipation medium is effectively managed to enhance the performance and longevity of the electronic apparatus.
