1. A cold plate, comprising:
a housing provided with a chamber;
a base combined with the housing to form a working space separated from the chamber and connected to the chamber and the working space via an interconnecting opening to allow a working medium to flow in the chamber and the working space;
heat transfer fins disposed on an inner side of the base for transferring thermal energy created by a heat source in contact with an outer side of the base to the working medium in the working space;
a first pump disposed in the working space for partitioning the working space into a heat absorption space and a drainage space and for driving the working medium to flow from the heat absorption space to the drainage space; and
a second pump disposed in the chamber for driving the working medium to flow from the chamber to the heat absorption space via the interconnecting opening.
