HEAT DISSIPATION STRUCTURE FOR HIGH-CAPACITY CIRCUIT BREAKER

原文（中国語）

The present disclosure discloses a heat dissipation structure for a high-capacity circuit breaker, which includes: a circuit breaker body, inner heat dissipating fins, outer heat dissipating fins, and chimney cover plates; wherein the inner heat dissipating fins are disposed on an inner side of a base plate on an upper surface of a housing of the circuit breaker body, the outer heat dissipating fins are disposed on an outer side of the base plate on the upper surface of the housing of the circuit breaker body, and the outer heat dissipating fins are topped with the chimney cover plates. The inner and outer heat dissipating fins are arranged parallel to each other, are equidistantly distributed, and are perpendicular to the base plate. The chimney cover plates are made of epoxy resin and abut the top of the outer heat dissipating fins and are in parallel with the base plate.
