Abstract
The invention provides a high heat dissipation outdoor electric cabinet which belongs to the field of power facilities. The high heat dissipation outdoor electric cabinet comprises a metal casing in a cuboid shape, heat dissipation areas are arranged on the two sides of the casing, a heat dissipation hole is formed in the center of a top plate of the casing, a cover plate is further arranged above the top plate, a ventilating area is formed between the top plate and the cover plate, the vertical size of the center of the ventilating area is small, and the vertical size of the periphery of the ventilating area is large, so that more gas flow can be collected on the outer side of the ventilating area to enter the center of the ventilating area, and the wind speed of the center of the ventilating area can be as large as possible. Compared with the existing power cabinet, the high heat dissipation outdoor electric cabinet improves heat dissipation efficiency to a large extent.
Description
Technical field
The present invention relates to the electric power facility field, especially, relate to a kind of outdoor electric cabinet.
Background technology
In the power infrastructures field, electric power cabinet is common device, for current electric power cabinet, mainly a metal shell that roughly is cuboid, consists of; Because inside is mounted with the power equipment of continuous firing, and there is large electric current, therefore the electric power cabinet internal calorific power is larger, need to offer radiating area on the surface of shell, and current radiating area to be all the strip shutters that are opened in electric power cabinet shell both sides by symmetry form; Due to its symmetry, inside and outside electric power cabinet, during heat-shift, can only carry out in the mode of natural convection air, therefore heat radiation slowly, is unfavorable for the high power operation of electric power cabinet.
Summary of the invention
For the problems referred to above, the object of the present invention is to provide a kind of high heat radiation outdoor electric cabinet, this electric power cabinet is compared with current electric power cabinet, has improved largely radiating efficiency.
The technical scheme that technical solution problem of the present invention adopts is: this height heat radiation outdoor electric cabinet comprises the metal shell that is rectangular-shaped, described shell both sides offer radiating area, the top board central authorities of described shell offer louvre, and described top board top also is provided with a cover plate, forms a plenum area between described top board and cover plate.
As preferably, the vertical size of described plenum area central authorities is little, and the vertical size of surrounding is large; Thereby make the plenum area more air-flow of can amassing wealth by heavy taxation in the outside enter plenum area central authorities, so that the wind speed of plenum area central authorities is large as far as possible.
As the further restriction of above-mentioned optimal way, described top board is an arch sheet upwards arched upward, and described cover plate is an arch sheet arched upward downwards, with this, forms described plenum area; Again further, a shield also is stamped in described cover plate top, and described shield is an arch sheet upwards arched upward, thereby makes rainwater rapidly to the surrounding landing on shield, avoid electric power cabinet top ponding.
As preferably, between described top board and described cover plate, by vertical shaped steel, through bolt pair, be connected or weld.
Beneficial effect of the present invention is: this height heat radiation outdoor electric cabinet in use, when the wind of any wind direction during through the top of electric power cabinet, the air velocity of electric power cabinet top board above and below differs greatly, according to bernoulli principle, cause the pressure of top board top to be significantly less than the electric power cabinet internal pressure, make the electric power cabinet inner air be extruded by force electric power cabinet, and from the plenum area air amount of shell both sides as a supplement, as can be seen here, this electric power cabinet can pass through convection current by force to realize heat radiation, has obviously high-strength radiating effect.
The accompanying drawing explanation
Fig. 1 is the schematic diagram of an embodiment of this height heat radiation outdoor electric cabinet.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further described:
In the embodiment shown in fig. 1, this height heat radiation outdoor electric cabinet comprises the metal shell 1 that is rectangular-shaped, and described shell 1 both sides offer radiating area 10, the arch sheet of top board 11 for upwards arching upward of described shell 1, and central authorities are high, and surrounding is low; And top board 11 central authorities offer louvre 110, and described top board 11 tops also are provided with a cover plate 21, and described cover plate 21 is an arch sheet arched upward downwards, and its central authorities are low, and surrounding is high, like this, form a plenum area 4 between described top board 11 and cover plate 21; The vertical size of these plenum area central authorities is little, and the vertical size of surrounding is large; From any one vertical section, it is horn-like that the two ends of this plenum area all are; Like this, when electric power cabinet top, to have an air stream out-of-date, and described plenum area 4 has just had building-up effect, makes air draught speed be strengthened further in the central authorities of plenum area 4, makes the central authorities of plenum area 4 have large as far as possible air velocity.
In the present embodiment, a shield 22 also is stamped in described cover plate 21 tops, and described shield 22 is an arch sheet upwards arched upward, thereby makes rainwater rapidly to the surrounding landing on shield 22, avoid electric power cabinet top ponding; Be connected or weld through bolt pair by vertical shaped steel 3 between described top board 11 and described cover plate 21; The quantity of described shaped steel 3 and distribution are comparatively random, as long as have enough holding strengths, and the formation of ventilating are not blocked and are got final product.
This height heat radiation outdoor electric cabinet in use, when the air-flow of any wind direction blows the top through electric power cabinet, as shown in the lateral arrows of Fig. 1 middle and upper part, this airflow limitation is in described plenum area 4, this makes the air velocity of electric power cabinet top board 11 above and belows differ greatly, according to bernoulli principle, cause the pressure of top board 11 tops to be significantly less than the electric power cabinet internal pressure, make the electric power cabinet inner air be extruded by force electric power cabinet, as shown in the arrow at 110 places of louvre in Fig. 1, and as shown in the arrow at 10 places of plenum area in Fig. 1, from plenum area 10 air amounts of shell 1 both sides as a supplement, as can be seen here, this electric power cabinet can pass through convection current by force to realize heat radiation, there is obviously high-strength radiating effect.
The foregoing is only preferred mode of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
