Abstract:
1. A cooling system for large power transformers, comprising: a housing having a compartment and an oil inlet being in fluid communication with said compartment; a transformer unit disposed in said compartment and including a plurality of large power transformers; a heat-dissipating unit disposed in said compartment and including a fluid inlet port member, a fluid outlet port member, a heat conductor, and a plurality of heat exchange pipes being fluid communication with said fluid inlet port member and said fluid outlet port member, said fluid inlet port member having an inlet disposed outwardly of said housing, said fluid outlet port member having an outlet disposed outwardly of said housing, said fluid inlet port member and said fluid outlet port member of said heat-dissipating unit configured as metal tubes that extend out of said housing along a first direction, said heat conductor being thermal contact with said heat exchange pipes, said heat exchange pipes being arranged along said first direction, each of said heat exchange pipes extending along a plane that is perpendicular to said first direction, said heat-dissipating unit including two clamps, said clamps being fixed in said housing for clamping said heat conductor therebetween, said heat exchange pipes extending through said clamps and said heat conductor, said heat exchange pipes being configured to extend along a snake-like route, each of said heat exchange pipes having a set of straight pipe portions extending along a second direction that is perpendicular to said first direction; and a cooling oil being introduced into said compartment of said housing through said oil inlet such that said transformer unit, said heat conductor, and said heat exchange pipes are immersed in said cooling oil.
