In one embodiment, the immersion cooling system further includes an external cooling unit coupled to the condenser unit, the external cooling unit includes an air blower that blows an airflow through one or more condensing coils of the condenser unit and a cooling nozzle to spray one or more condensing coils of the condenser unit using a cooling liquid medium (e.g., water) from an ambient source. In one embodiment, the heat exchange core is situated above the immersion tank but below the condenser unit.

In one embodiment, the heat exchange core includes a set of pipes or tubes, wherein vapor of the first phase change liquid circulates at an interior to the set of pipes, wherein the second phase change liquid in contact with an exterior to the set of pipes extracts heat from the vapor causing the vapor to condense to liquid phase. In one embodiment, boiling point of the second phase change liquid is lower than boiling point of the first phase change liquid.

In one embodiment, the condenser unit comprises a riser compartment and a down comer compartment, wherein second phase change liquid in vapor phase rises in the riser compartment and second phase change liquid in liquid phase falls down in the down comer compartment. In one embodiment, the boiling point of the second phase change liquid is adjustable and controlled based on a negative pressure applied at the condenser unit.
