1. A two-phase cold plate, comprising:
a base;
an upper cover installed on the base;
a heat exchange cavity formed between the base and the upper cover; and
a cooling fin module installed in the heat exchange cavity, wherein the upper cover comprises:
at least one nozzle module; and
a plurality of two-phase fluid channels located on both sides of the at least one nozzle module, wherein the at least one nozzle module sprays a heat dissipating fluid to the cooling fin module, and the heat dissipating fluid flows along the cooling fin module to the two-phase fluid channels on the both sides of the at least one nozzle module to cool the cooling fin module, wherein the at least one nozzle module comprises:
a first nozzle module; and
a plurality of second nozzle modules respectively located on both sides of the first nozzle module, wherein an entrance hole of the first nozzle module is smaller than entrance holes of the second nozzle modules, wherein at least one of the first nozzle module and the second nozzle modules comprises:
a plurality of front nozzles;
at least one slotted nozzle; and
a plurality of rear nozzles, the front nozzles, the at least one slotted nozzle and the rear nozzles arranged in sequence.
