Abstract

The utility model provides a structure improvement of an outdoor electric appliance box, comprising a ventilating fan and a plurality of exhaust fine barrels shaped on the wall of the box relative to the ventilating fan, wherein the wall of each exhaust fine barrel is inclined downward, from inner to outer, a chamber is arranged between the ventilating fan and the exhaust fine barrels, and an opening is arranged under the outer wall of the chamber. The utility model can improve exhaust efficiency and automatically realize rain shield function.

Description

A kind of structural improvement of outdoor electric appliance box

Technical field:

The utility model relates to the case radiation technology, refers in particular to a kind of structural improvement of outdoor electric appliance box.

Background technology:

The electric appliance box of a large amount of electronic components is housed now, owing to can produce a large amount of heat energy in the electronic component course of work, make the internal temperature of casing more and more higher, in order to address this problem, the engineering staff has designed multiple heat dissipating method, water-cooled and air-cooled for example, even the electric appliance box side plate dismantled, water-cooled is somewhat expensive in these methods, and the box side of dismantling can make electronic component be subjected to the influence of external factor easily, so it is air-cooled using maximum methods at present, just utilize ventilating fan that the hot blast of electric appliance box inside is discharged outside the casing, its structure has installing hole as shown in Figure 1 on the electric appliance box wall body, on this installing hole ventilating fan is housed, in addition in order to prevent that rainwater from infiltrating, be equipped with at the casing lateral wall on the position of ventilating fan the rain cover that is bent into 90 ° is installed, air is subjected to stopping of rain cover during air draft like this, ventilation efficiency is low, influences cooling-down effect.

Summary of the invention:

The purpose of this utility model is in order to solve the shortcoming of above-mentioned prior art, provide a kind of simple in structure, air draft rapidly, effective rainproof outdoor electric appliance box.

For achieving the above object, the technical scheme that the utility model provides is: a kind of structural improvement of outdoor electric appliance box, this electric appliance box includes ventilating fan and the thin tube of a plurality of air-out of moulding on position corresponding with ventilating fan on the casing wall body, the barrel of the thin tube of each air-out all is shaped to from-inner-to-outer and is tilted to down, be provided with cavity between ventilating fan and the thin tube of air-out, the wall body below, the outside of this cavity has air inlet.

The utility model has been cancelled rain cover than original structure, the ventilating fan installing hole changes the thin tube of a plurality of air-out into, the barrel of the thin tube of each air-out all is processed into from-inner-to-outer and is tilted to down, the function that automatic realization is kept off the rain, in addition because the existence of cavity makes generation negative pressure in the air draft process cavity, in order to eliminate negative pressure, on the wall body of the outside of cavity, have air inlet, the utlity model has simple in structure, heat radiation fast.

Description of drawings:

Fig. 1 is an electric appliance box air discharging and radiating structure prior art constructions schematic diagram;

Fig. 2 is the schematic diagram of the electric appliance box air discharging and radiating structure of the utility model preferred embodiment;

Fig. 3 is the utility model perspective view.

Embodiment:

As accompanying drawing 2, shown in the accompanying drawing 3, the electric appliance box of this preferred embodiment, this electric appliance box includes ventilating fan 1 and the thin tube 2 of a plurality of air-out of moulding on position corresponding with ventilating fan 1 on the casing wall body, the barrel 4 of the thin tube of each air-out all is shaped to from-inner-to-outer and is tilted to down, because the existence of barrel 4 just can realize keeping off the rain automatically, cancel original rain cover, save cost, for ventilating fan 1 is installed, being provided with in casing provides the wall body 6 that ventilating fan 1 usefulness is installed, and forms cavity 3 between this wall body 6 and the wall box, but can produce negative pressure in the cavity 3 during air draft, in order to offset negative pressure, below the wall body of the outside of this cavity 3, have air inlet 5.

Also can all be processed into the integral body that the casing lateral wall is positioned at the cavity scope the thin tube of air-out in addition, can realize the purpose of this utility model equally.Certainly the existence of cavity is because the needs that ventilating fan is installed are provided with one wall body is installed is produced, if installation wall body of the present utility model changes frame structure into, can remove cavity equally, also just can not have the influence of negative pressure to air draft.

Claims
