A kind of regulator cubicle improving heat dispersion
Technical field
The utility model relates to a kind of regulator cubicle, especially a kind of regulator cubicle improving heat dispersion.
Background technology
Regulator cubicle processes by steel matter the cupboard normally worked for protection components and parts.Regulator cubicle makes material and is generally divided into hot rolled steel plate and cold-rolled steel sheet two kinds.The relative hot rolled steel plate of cold-rolled steel sheet more made of soft, is more suitable for the making of regulator cubicle.Regulator cubicle is of many uses is mainly used in chemical industry, environmental protection industry (epi), electric power system, metallurgical system, industry, nuclear power industry, and security against fire is monitored, transportation industry etc.
Its shape major part of existing regulator cubicle is rectangular-shaped cabinet; cabinet door is generally provided with in the front of cabinet; cabinet door can arrange the settings such as ammeter, voltmeter, console switch, button usually; there are in the inside of cabinet the parts such as mounting panel, bus bar, terminal board; for installing the electric components such as circuit breaker, transformer, Switching Power Supply, PLC, frequency converter; certainly be also provided with cable at cabinet, control the circuit such as electric wire, holding wire; some regulator cubicle bottoms are also provided with universal wheel, and regulator cubicle can be moved.
Crowd knows known, in the process that electric component uses, the electric energy conversion of a part is in order to heat energy, and along with the increase of service time, in regulator cubicle, air themperature obviously raises, which results in the instability of electric component work, therefore usually on electric component, be generally all provided with ventilating opening, the hot-air be gathered in regulator cubicle can be discharged by ventilating opening, and outside hot-air can enter from ventilating opening, to reduce the temperature in regulator cubicle, guarantee the normal operation of electric component.General ventilating opening all makes venetian blind type, to increase local ventilation face, in addition in order to improve ventilation effect, being also provided with fan and carrying out water conservancy diversion to air in partial electric cabinet, increases thermal diffusivity.
The website of State Intellectual Property Office discloses a lot of regulator cubicle, mainly contains No. 201420539188.2 patents " a kind of Novel electrical cabinet of ventilating heat-proof "; 201320781794.0 number patent " a kind of regulator cubicle "; 201320292063.X patent " a kind of regulator cubicle ", these regulator cubicles are all to improve air permeability, can as the immediate prior art of present patent application.
In addition, as the one of regulator cubicle, outdoor electric cabinet is usually disposed in the outdoor, and it can only be placed on due to the needs of position the outdoor that weather is comparatively severe, temperature mistress difference is larger, in use, various insect easily climbs into inside, therefore to outdoor electric cabinet, needing when designing to consider heat radiation, also needing to consider insect protected.Now commercially there is a collection of regulator cubicle, it is provided with a kind of outstanding knapsack at the cabinet back side, knapsack is provided with ventilation hole or shutter, the setting of knapsack increases ventilating surface, and radiating effect can improve, but can not insect protected, if improved the structure of knapsack, and insect preventing structure is set, the result of use of this regulator cubicle just has one and significantly promotes, and the purpose of this utility model is exactly to do such improvement.
Summary of the invention
The purpose of this utility model is deficiency in order to solve above-mentioned technology and a kind of regulator cubicle improving heat dispersion designed.
A kind of regulator cubicle improving heat dispersion designed by the utility model, comprise cabinet, cabinet is hinged with cabinet door, electric meter installing port and electric button installing hole is provided with on cabinet door top, the mounting panel for mounting electrical element is provided with in cabinet, a heat dissipating housing is provided with at the cabinet back side, the bottom of heat dissipating housing is communicated by opening with cabinet, the back side of heat dissipating housing is provided with shutter, the one side that the top of heat dissipating housing is relative with cabinet is open region, the position relative with described open region, the cabinet back side is covered with pore, the described cabinet back side is provided with two the card muscle in left and right, each card muscle is provided with the first draw-in groove, the region that described heat dissipating housing is relative with the first draw-in groove is provided with the second draw-in groove, fly net is fitted with between the first draw-in groove and the second draw-in groove, the top of two fly nets in left and right is all connected on a lid, this lid is positioned at card muscle and heat dissipating housing top, described pore is all between the fly net of two, left and right.
This principle improving the regulator cubicle of heat dispersion is: the electric component installed on a mounting board in use generates heat, air themperature in cabinet is raised, hot-air in cabinet enters heat dissipating housing from pore, and discharged by the shutter at the heat dissipating housing back side, also discharge by fly net simultaneously; On the other hand, the hot-air that in cabinet, position is lower enters heat dissipating housing from opening, and discharges from the shutter at the heat dissipating housing back side, also discharges by fly net simultaneously, and such radiating surface is comparatively large, and heat radiation gap is also large, can improve heat dispersion; The setting of two fly nets in left and right, seals the gap that the cabinet back side and heat dissipating housing are formed together with lid, can play radiating effect on the one hand, can prevent worm, foreign material etc. from directly entering open region on the other hand, can improve the fail safe of use.
Further scheme is: described fly net is made up of housing and the wire netting being positioned at housing, and described housing size matches with described first draw-in groove and the second draw-in groove.
The regulator cubicle of the improved heat dispersion designed by the utility model, its beneficial effect is: perfect heat-dissipating, is conducive to the normal operation of content electric component.
