BACKGROUND Technical Field The instant disclosure relates to an immersion cooling system, particularly an immersion cooling system having a baffle assembly. Related Art An immersion cooling system usually refers to a system capable of transmitting the heat generated by an electronic device to a heat transfer fluid by submerging the electronic device in a heat transfer fluid; therefore, the temperature of the electronic device can be reduced. Hence, the working temperature of the electronic device can be maintained within a proper range to reach desired working performance and service life of the electronic device. In the process of transferring the heats from the electronic device to the heat transfer fluid, the heat transfer fluid with a lower boiling point will be first boiled and vaporized, and thus bubbles in a large amount will be quickly generated at interfaces (as well as the proximity of the interfaces) between the electronic device and the heat transfer fluid. These bubbles will be widely dispersed in the heat transfer fluid.
