Description

Invisible heat dissipation comprehensive box

Technical Field

The utility model relates to an electrical equipment technical field, concretely relates to stealthy heat dissipation synthesizes case.

Background

The low-voltage distribution comprehensive box is a switch device which is assembled with switch equipment, a measuring instrument, protective electric equipment and auxiliary equipment in a closed or semi-closed cabinet body according to the electric wiring requirement, is usually installed at the outlet of the low-voltage side of a transformer of a distribution station area or the branch of a line, and is used for immediately cutting off a power supply in a short time after the line is in fault protection, so as to ensure the safe operation of a distribution line. Because the low-voltage comprehensive distribution box operates outdoors and is sealed too tightly, high temperature is generated by direct irradiation of sunlight, and heat is generated by the operation of an internal low-voltage electric appliance, so that the internal temperature of the box body is overhigh. In order to improve the heat dissipation effect of the integrated box in the prior art, air inlets or ventilation windows are often arranged on two sides of a box body, but the heat dissipation effect of the heat dissipation structure is still not ideal.

SUMMERY OF THE UTILITY MODEL

The utility model discloses it is providing stealthy heat dissipation synthesis case to anticipate, solves among the prior art the not good problem of synthesis case radiating effect.

Has the advantages that: the heat that the inside electrical equipment of case body produced is absorbed by the air and becomes the hot gas, and hot gas density is lower relatively, so can flow to the upper end of case body, and then can diffuse outside the box through clearance and louvre between roof and the bottom plate, and relative prior art side direction inflow outflow gas, this scheme complied with the flow trend of hot gas, and the hot gas outflow rate increases, has promoted the radiating effect. Meanwhile, the radiating holes face downwards, so that external dust and rainwater are prevented from entering.

Furthermore, a mounting plate is fixedly connected to the bottom plate. The mounting plate can be fixed with the side wall of the box body in a welding or screw mode, so that the cover plate and the box body can be conveniently mounted.

Further, an inverted cone is fixed on the lower surface of the top plate. The side face of the conical body has inclination relative to the horizontal top plate, so that the side face of the conical body enables hot gas rising below to flow to the heat dissipation holes around, the hot gas is discharged as soon as possible, the outflow rate of the hot gas from the heat dissipation holes is further improved, and the hot gas is prevented from being gathered on the lower surface of the top plate.

Further, the cone is a rectangular pyramid.

The side wall of box body is with four more, and every side of rectangular pyramid sets up like this corresponding the side wall of a box body, can promote the guide to the hot gas.

Furthermore, a cavity is formed between the conical body and the top plate, and air holes communicated with the cavity are formed in the top plate.

In rainy days, rainwater can enter the cavity through the air holes to be collected, and the rainwater can absorb heat in the box body through the conical body in the cavity; particularly, under the irradiation of sunlight, rainwater can be evaporated into water vapor to be diffused out of the air holes, so that the temperature in the box body is reduced.

Furthermore, a filter screen is fixed at the position of the top plate corresponding to the air holes. The entering amount of dust and other impurities in the chamber is reduced.

Further, the conical body is made of heat conducting materials. The heat absorption rate of rainwater in the chamber is improved.

Furthermore, the side wall of the box body is provided with an air inlet.

Under the windy condition in the external world, external wind passes through in the air intake entering case body for the internal gas pressure of case briefly risees, promotes the hot gas and flows out from the louvre.

Furthermore, a dust guard is fixed above the air inlet. And dust and rainwater are prevented from entering the box body from the air inlet.

Further, the conical body and the box body are fixed by screws.

Compared with the welding mode, the welding mode is fixed, and the corrosion of rainwater in the cavity to the joint can be reduced by adopting the screw fixing phase to fix the welding.

Detailed Description

The following is further detailed by way of specific embodiments:

reference numerals in the drawings of the specification include: the box comprises a box body 1, an air inlet 11, a dust guard 12, a cover plate 2, a top plate 21, a bottom plate 22, air holes 23, heat dissipation holes 24, a mounting plate 25, a conical body 3 and a cavity 31.

The first embodiment is basically as follows:

stealthy heat dissipation synthesis case, as shown in fig. 1 and fig. 2, including case body 1 and apron 2, apron 2 is connected in the upper end of case body 1, has seted up a plurality of air intakes 11 on the lateral wall of case body 1 left and right sides, and air intake 11 department is fixed with dust guard 12, avoids dust and rainwater to pass through air intake 11 and gets into in the case body 1. The box body 1 is also provided with a switch door, which is convenient for the operation and inspection of internal devices.

As shown in fig. 2 and 3, the cover plate 2 includes a top plate 21 and a bottom plate 22, a gap is left between the top plate 21 and the bottom plate 22, the bottom plate 22 is located at the outer side of the peripheral edge of the upper end of the box body 1, a plurality of heat dissipation holes 24 are formed around the bottom plate 22 corresponding to the box body 1, a mounting plate 25 is fixed at the edge of the bottom plate 22 close to the side wall of the box body 1, the mounting plate 25 is attached to the inner surface of the side wall of the box body 1, and the mounting plate 25 is fixed with the box body 1 by welding or screws. The top plate 21, the bottom plate 22 and the mounting plate 25 are integrally formed.

Since the heat radiating hole 24 is located on the bottom plate 22, the heat radiating hole 24 faces downward, and the heat radiating hole 24 communicates with the internal space of the box body 1 through the gap between the top plate 21 and the bottom plate 22. The heat generated by the electrical equipment inside the box body 1 is absorbed by the air to become hot gas, and the hot gas has relatively low density, so the hot gas flows to the upper end of the box body 1, and further flows to the heat dissipation holes 24 through the gap between the top plate 21 and the bottom plate 22 and is diffused to the outside of the box body. Under the condition that wind exists outside, the outside wind enters the box body 1 through the air inlet 11, so that the gas flowing in the box body 1 is increased, and the hot gas is promoted to flow out of the heat dissipation holes 24. Meanwhile, the heat dissipation holes 24 face downward, so that dust and rainwater are prevented from entering the box body 1 through the heat dissipation holes 24.

Example two:

the difference from the first embodiment is that, as shown in fig. 4 and 5, an inverted cone 3 is fixed to the lower surface of the top plate 21, and the fixing manner may be a welding manner or a screw manner, in this embodiment, the cone 3 is specifically a quadrangular pyramid. The inclined surface on the conical body 3 enables the hot gas rising from the lower part to flow to the periphery, further improves the outflow rate of the hot gas from the heat dissipation holes 24, and avoids the hot gas from being accumulated on the lower surface of the top plate 21.

A cavity 31 is formed between the conical body 3 and the top plate 21, a plurality of air holes 23 are formed in the position, corresponding to the conical body 3, of the top plate 21, the air holes 23 are communicated with the cavity 31, and a filter screen is fixed on the lower surface of the top plate 21 corresponding to the positions of the air holes 23.
