Abstract
A cooling system includes a housing having a compartment and an oil inlet. A transformer unit is disposed in the compartment and includes a plurality of large power transformers. A heat-dissipating unit is disposed in the compartment and includes a fluid inlet port member, a fluid outlet port member, a heat conductor, and a plurality of heat exchange pipes. The heat conductor is in thermal contact with the heat exchange pipes. The heat exchange pipes are arranged along a first direction. Each of the heat exchange pipes extends along a plane that is not parallel to the first direction. A cooling oil is introduced into the compartment through the oil inlet such that the transformer unit, the heat conductor, and the heat exchange pipes are immersed in the cooling oil.
