The left and right sides inside the radiating shell is equipped with the heat insulating strip being arranged in a linear, and the region between two heat insulating strips
Waist shaped heat dispersing hole is opened up, the inner bottom surface of the radiating shell is equipped with the filler strip of the rectangular shape to raise upward, the filler strip
It is prepared by heat-insulated organic silicon rubber, the front of the radiating shell opens up two for installing the fan of heat loss through convection
Round mouth is installed, and the outer ledge of fan installation round mouth is equipped with the bulge loop being arranged with its concentric, the outer stationary plates
Four right angles on the inside of be equipped with bolt hole, and the outer stationary plates be equipped with power supply string holes.
Further, the front top of the radiating shell is equipped with the U-shaped groove being recessed vertically downward, and described U-shaped
Groove is located at the middle position at radiating shell front top.
Further, the outer stationary plates upper face is equipped with the heat dissipation square hole of equidistant arrangement.
Further, the heat insulating strip and the radiating shell are by being integrally formed preparation, and the heat insulating strip
Cross section be isosceles trapezoid shape.
Working principle of the utility model is: the left and right sides inside radiating shell is equipped with the heat insulating strip being arranged in a linear, and
And the region between two heat insulating strips opens up waist shaped heat dispersing hole, heat insulating strip not only strengthens the intensity of radiating shell wall surface, reduces
Since fan in the process of running vibrate by bring, and the contact area to power supply can be reduced, increase heat-dissipating space；It dissipates
The front of hot shell opens up two fans for installing heat loss through convection and installs round mouth, it is not necessary that the mounting plate of fan is separately provided,
Production cost is reduced, and the dust stratification generated can be accumulated in the region between filler strip, be convenient to clean.
(2) the utility model has the advantages that
The utility model has the beneficial effects that compared with the prior art, the utility model reduces since fan was being run
Bring is vibrated in journey, and can reduce the contact area to power supply, increases heat-dissipating space；And it is not necessary that fan is separately provided
Mounting plate, reduce production cost, the dust stratification of generation can be accumulated in the region between filler strip, be convenient to clean, and solve existing skill
Dust stratification of the radiator of the switch power module of art in bottom does not allow easy-clear, and due to the shell wall of heat dissipation main casing compared with
Thin, fan open-type noise is larger, due to being Full connected shell wall, the undesirable technical problem of heat dissipation effect.
