Claim:
1. A cooling device for a transformer, wherein the transformer includes a core formed with a magnetic material, and a primary winding and a second winding wound around a substantially center part of the core and separated from each other, comprising: a heat-dissipating panel disposed between the primary winding and the secondary winding and configured to release heat generated from the core, the primary winding, and the secondary winding to an exterior of the transformer using heat conductance and exposed edges of the primary winding and the secondary winding; and a heat sink contacting a bottom of the core and configured to absorb heat from the core and dissipate the absorbed heat to the exterior of the transformer, the heat sink including a plurality of coupling members with a predetermined height at an upper surface thereof, wherein the coupling members protrude upward from the heat sink, and wherein the heat-dissipating panel protrudes outward from the primary winding and the secondary winding, and the protruded portion of the heat-dissipating panel is heat-conductively coupled with the coupling member.
