US Patent 11602075 Cooling apparatus providing immersion cooling

A cooling apparatus for cooling a to-be-cooled device is described. The cooling apparatus includes a cabinet body configured to contain a cooling medium for at least partially immersing the to-be-cooled device, a volumeter for detecting a volume of the cooling medium in the cabinet body, and a storage tank storing the cooling medium. The storage tank and the cabinet body are communicatively connected to each other. Further, when the volumeter detects that the volume of the cooling medium in the cabinet body is lower than a preset volume, the storage tank and the cabinet body come into mutual communication so that the cooling medium in the storage tank is transferred into the cabinet body.
