[embodiment]
In order to make the technical solution of the utility model and technique effect clearly, be described in detail below in conjunction with the embodiment of drawings and Examples to this patent.
Embodiment one:
As Fig. 1 to Fig. 5, the convertible frequency air-conditioner electric-controlled box of the good heat dissipation effect in the present embodiment, comprises box body 1, radiator 2 and cover 3.
Box body 1 is rectangular, upper opening, suitable with the pcb board (not shown) profile of convertible frequency air-conditioner, and adjacent two sides are equipped with at least one ventilating window 11, and ventilating window 11 is made up of the ventilation hole 111 of multiple " Z " shape." Z " shape ventilation hole 111 two turnings are right angle, and the width of its two ends vent passages 1111 is greater than the width of stage casing vent passages 1112, and the width of stage casing vent passages 1112 is not more than 1mm.Ventilation hole 111 uniform intervals distributes, longitudinal extension, the demarcation strip 112 that the ventilation hole 111 of " Z " shape is " Z " shape by adjacent two horizontal cross-sections is formed, this ventilating window is for the ventilating window of direct perforate, two ends vent passages 1111 not only ensure that the radiating effect of pcb board, and stage casing vent passages 1112 and corner design can prevent insect, entering of the foreign matters such as dust, extend the working life of pcb board in electric-controlled box.Box bottom top surface edge is provided with the fixed leg 12 of fixing pcb board, bottom surface is provided with a hollow hole 13 at the high pressure heat radiation elements place of pcb board, this hollow hole 13 is suitable but overall dimension is slightly less than radiator 2 with the profile of radiator 2, and hollow hole 13 is just to a ventilating window of side.Box body side is corresponding in pcb board outlet position is provided with the wire hole 14 matched with wire external diameter, wire hole 14 the smooth of the edge, avoids the insulating barrier of damage electric wire and there is electric leakage risk.Box body side is provided with multiple groove 15 that caves in, and the bottom surface that the groove that caves in is corresponding is provided with fixing hole 16, and this hole is used for fixing of electric-controlled box and convertible frequency air-conditioner.
Radiator 2 is connected and composed by bottom surface 21 and multiple radiating fins 22 vertical with bottom surface 21.Box bottom outer surface is located at by radiator 2, radiator bottom surface 21 and being fixedly connected with by screw with box bottom, and seals hollow hole 13.Radiating fin 22 liang of outer surface undulates, effectively expand the area of dissipation of radiating fin; Radiating fin 22 is facing to the stepped gradually high setting of blower fan (not shown) of convertible frequency air-conditioner; When convertible frequency air-conditioner works, blower fan rotates, and air-flow blows to radiating fin 22, and the heat of radiating fin 22 is taken away by blower fan electric current; Again due to the structure of its gradually high setting, air-flow can not be stopped by from the radiating fin close to blower fan, and the heat of the impact radiating fin far away with blower fan distributes, and the heat of the components and parts of the high heat dissipation capacity on pcb board can distribute evenly and rapidly.And the existence of the ventilating window 11 due to box body adjacent side, define similar L shape heat dissipation channel in whole electric-controlled box, on pcb board, the heat of components and parts can effectively distribute.
Cover 3 is located on box body 1 opening, is fixedly connected with by screw with box body 1.Fixing for the ease of box body, cover 3 is provided with the breach 31 identical with the slot cross-section that caves at corresponding box body groove 15 place of caving in.In order to prevent the deformation and fracture of cover, cover lower surface is provided with lattice-shaped reinforcement 32.
Certainly, " Z " shape ventilation hole two turnings in the present embodiment can also be other angles, and ventilation hole can also be other shapes, such as serpentine.
The foregoing is only the preferred embodiment of this patent, be not limited to this patent, for a person skilled in the art, this patent can have various modifications and variations.Within all spirit at this patent and principle, any amendment done, equivalent replacement, improvement etc., within the protection range that all should be included in this patent.
