Description

Electric appliance box with heat sinking function

Technical field:

The utility model relates to a kind of heat abstractor, is specially the electric appliance box with heat sinking function.

Background technology:

Along with the function of electronic devices and components increases gradually, performance is stable gradually, bring very great development for lighting industry product, lighting quality is improved, be widely used in Metal halogen lamp, sodium vapor lamp, fluorescent lamp, lightings such as electrodeless lamp, contrast with Inductive ballast, its light efficiency improves, the line power factor improves, operating efficiency improves, make the people unconsciously to stroboscopic, but the use of electronic devices and components requires relatively strictness, the particularly heat dissipation problem of power component to its operational environment, useful increase radiator is attached on the power device and dispels the heat with air, but be installed in the sealing electric appliance box, make it bulk temperature and improve, radiating effect is bad.

Practical content:

In order to solve deficiency of the prior art, the utility model provides the electric appliance box that a kind of radiating effect is better, heat radiation has heat sinking function faster.

The purpose of this utility model is to realize by following technical scheme:

Electric appliance box with heat sinking function, its primary structure comprises: loam cake, lower cover, base, top margin cover plate, power device, fixture, heat transfer device, heat sink strip etc.; Face is provided with heat sink strip in the left and right sides of loam cake, positive both sides at loam cake are provided with heat sink strip, central part in the loam cake front has one to be in the same labeling face highly of heat sink strip, respectively establish an external toothing button in the loam cake both side ends, the lower cover two sides are provided with heat sink strip, an interior joggle is respectively established in the end of lower cover both sides, the lower cover two side ends is equipped with heat transfer device near interior engagement buckle, power device is fixed on the heat transfer device with fixture, on the medial surface of lower cover both sides, establish holddown groove, on, lower cover is fixed between the top margin cover plate with screw by fixing hole, and the top margin cover plate is fixed on the end Cuo with screw.

Described upper and lower cover is equipped with a plurality of heat sink strips on its surface, helps scattering and disappearing of heat, and heat sink strip adopts lenticular, has increased area of dissipation greatly.

Described labeling face, the sign, printing or the paper that are used to install product paste.

Described heat sink strip is used to help the heat that produces in the electric appliance box outwards to transmit by aluminum hull and dispels the heat, and makes that heat is easier to be taken away by air.

Described heat transfer device, the heating power device with in the fixture fixed cap makes faster and better heat is dispelled the heat by heat sink strip of power device.

Described loam cake and lower cover both side ends respectively are provided with external toothing button and interior joggle respectively, and one recessed one protruding oblique catching groove well links together upper and lower cover on the joggle.

Described holddown groove is used for fixing the electronic devices and components wiring board is installed.

Owing to adopted above technical scheme, the utlity model has following beneficial effect:

1, simple in structure.

2, adopt the engagement draw-in groove fixedly connected, connect more reliable.

3, adopt heat transfer device, make faster and better heat is left of power device.

Description of drawings:

Fig. 1 is the structural representation after the upper and lower cover engagement of the present utility model.

Fig. 2 is the structural representation of the utility model loam cake.

Fig. 3 is the structural representation of the utility model lower cover.

Among the figure: 1 loam cake, 2 lower covers, 3 interior joggles, 4 external toothing buttons, 5 heat sink strips, 6 fixtures, 7 labeling faces, 8 holddown grooves, 9 heat transfer devices, 10, fixing hole, 11 power devices.

Embodiment:

Below in conjunction with accompanying drawing the utility model is described in further detail:
