Technical solution is used by the utility model solves its technical problem：A kind of heat radiation circuit breaker, including housing,
Several radiating grooves are offered on the two sides of the housing, the interior card of the radiating groove, which is set, is equipped with heat dissipation U-shaped board, the heat dissipation
Card slot is offered on the two relative side of slot, the outside of the two relative side of the heat dissipation U-shaped board is installed with strip,
The strip is fastened in the card slot, and the bottom of the heat dissipation U-shaped board is bonded with the bottom of radiating groove, the heat dissipation U-shaped board
Bottom be vertically installed with cooling fin.
The heat radiation circuit breaker of the utility model opens up radiating groove in the two sides of housing, reduces the wall thickness of housing, make
Heat in housing can pass to the heat dissipation U-shaped board being arranged in radiating groove faster, the heat absorbed in the U-shaped board that radiates,
A part is by the U-shaped board itself that radiates to external diffusion, and another part is by being arranged on the cooling fin of heat dissipation U-shaped board bottom to extending out
It dissipates, so as to play preferable cooling effect, the temperature in Shell of circuit breaker is made excessively not increase, protect breaker, no
The performance of breaker is influenced, extends the service life of breaker.
In order to accelerate the heat conductivility of heat dissipation U-shaped board, the heat dissipation effect for making the utility model breaker is preferable, the heat dissipation
The material of U-shaped board is metal material.
In order to make the heat dissipation of the breaker of the utility model more uniform, several radiating groove array settings.
In order to accelerate the heat dissipation of cooling fin, the cooling fin is corrugated plating.
Card slot is caught in and is detached from order to facilitate strip, and the cross-sectional shape of the card slot and the strip is semicircle.
The beneficial effects of the utility model are:The heat radiation circuit breaker of the utility model opens up scattered in the two sides of housing
Heat channel reduces the wall thickness of housing, the heat in housing is enable to pass to the heat dissipation being arranged in radiating groove faster U-shaped
Plate, the heat that absorbs in the U-shaped board that radiates, for a part by the U-shaped board itself that radiates to external diffusion, another part is scattered by being arranged on
The cooling fin of hot U-shaped board bottom, so as to play preferable cooling effect, makes the temperature in Shell of circuit breaker will not to external diffusion
Excessively raising, protects breaker, does not influence the performance of breaker, extend the service life of breaker.
