Abstract
The invention relates to the field of electrical equipment, in particular to an equipment cabinet and a guard plate thereof. The equipment cabinet comprises a skeleton and the guard plate fixedly arranged on the skeleton, wherein the guard plate has a heat dissipation surface, and the heat dissipation surface is a file surface; capillary grooves are arranged in the surface of the corresponding side of the guard plate to form the file surface, the heat dissipation efficiency is largely dependent on the surface area of a thermal convection surface, and can be improved by increasing the contact and convection surface areas; after the heat dissipation surface is set as the file surface, the thermal convection area is greatly increased, which is bound to increase the heat dissipation efficiency of the equipment cabinet; and in addition, the capillary grooves are arranged in the surface of the corresponding side of the guard plate to form the file surface without additional materials and devices, and the mechanics, structure and modal properties of the equipment cabinet can not be affected. Therefore, the heat dissipation efficiency of the equipment cabinet is improved under the premise of unaffecting the structure and efficacies of the equipment cabinet.
Description
Technical field
The present invention relates to the electric equipment field, especially a kind of equipment cabinet and backplate thereof.
Background technology
Along with high modularization and the integrated development of electric equipment, electronic equipment case has obtained using more and more widely.But, because after a plurality of electronic devices with heat generation characteristic concentrate in the equipment cabinet, what at first cause is exactly the violent intensification problem of equipment cabinet, and the rising of in-cabinet temperature will directly cause the decline of the performance of electronic device wherein, even causes the inefficacy of some equipment.Therefore at present common way is that related device by the outside cools off equipment cabinet, thereby guarantee that it moves under good state, wherein the most frequently used way is exactly to adopt the heat-delivery surface of cold air flush equipment cabinet, yet, present equipment cabinet or adopt common flat board as backplate, be exactly to increase corresponding material or device (such as radiating fin) at equipment cabinet, adopt dull and stereotyped as the next inefficiency of carrying out heat exchange with cold air of backplate, to the cooling effect of equipment cabinet and limited, this point is confirmed in actual production, although increase the heat exchanger effectiveness that corresponding material or device can improve equipment cabinet to a certain extent at equipment cabinet, but but can affect the original structure of equipment cabinet and effect, even can destroy its function.
Summary of the invention
The object of the present invention is to provide a kind of equipment cabinet, under the prerequisite of the structure that does not affect equipment cabinet itself and effect, to improve the radiating efficiency of equipment cabinet.
Simultaneously, the present invention also aims to provide the said equipment cabinet backplate.
In order to address the above problem, equipment cabinet of the present invention is by the following technical solutions: a kind of equipment cabinet, comprise skeleton and fixedly be assemblied in backplate on the described skeleton, backplate has heat-delivery surface, described heat-delivery surface is the file face, forms after capillary groove is set on the respective side surface of described file face by backplate.
Described capillary groove is straight flute parallel to each other.
The longitudinal groove that described capillary groove is divided into lateral trench and intersects with lateral trench.
The cross section of described groove is circular arc, rectangle, trapezoidal or inverted triangle.
Along equidirectional extend and adjacent two grooves between form every band, be triangle every the cross section of band.
Equipment cabinet backplate of the present invention is by the following technical solutions: the equipment cabinet backplate, and this backplate has heat-delivery surface, and described heat-delivery surface is the file face, forms after capillary groove is set on the respective side surface of described file face by backplate.
Described capillary groove is straight flute parallel to each other.
The longitudinal groove that described capillary groove is divided into lateral trench and intersects with lateral trench.
The cross section of described groove is circular arc, rectangle, trapezoidal or inverted triangle.
Along equidirectional extend and adjacent two grooves between form every band, be triangle every the cross section of band.
Because equipment cabinet of the present invention is made as the file face with the heat-delivery surface of its backplate, after being set, capillary groove forms on the respective side surface of described file face by backplate, and radiating efficiency depends on the surface area of heat convection surface to a great extent, increase contact and convective surface area and can improve its radiating efficiency, based on this principle as can be known, equipment cabinet of the present invention has increased its thermal convection area after its heat-delivery surface is made as the file face greatly, this certainly will will improve the radiating efficiency of equipment cabinet greatly, in addition, because described file face is to form after capillary groove is set on the respective side surface by backplate, the setting of capillary groove does not need to enter extra materials and devices, also can not ring the mechanics of equipment cabinet, structure, the performances such as mode, this shows, equipment cabinet of the present invention has improved the radiating efficiency of equipment cabinet under the prerequisite of the structure that does not affect equipment cabinet itself and effect.
Further, capillary groove is made as straight flute parallel to each other can makes in use the bearing of trend of capillary groove consistent with the flow direction of cold air, thereby accelerate flowing of cold air, and then increase the radiating efficiency of equipment cabinet; The longitudinal groove that capillary groove is divided into lateral trench and intersects with lateral trench, the capillary groove that then intersects can form granular one by one small embossment at the heat-delivery surface of backplate, thereby further increase the area of heat-delivery surface, accelerate radiating efficiency, in addition, according to the characteristic that heat is transmitted, the easier heat conduction of described small embossment also guides to its tip (top) with heat, and this has also increased the radiating efficiency of equipment cabinet from another point of view; To be made as every the cross section of band and be triangle, can make the ridge shape projection that forms a lot of on the heat-delivery surface of backplate, and a line is formed on the top of projection, this has utilized the characteristic of hot transmission equally, so that heat more easily arrives the top of projection, and then taken away by cold air.
