The improved radiator is simple in structure and convenient to manufacture. The heat radiation effect of the radiator is increased, the electric appliance installation board in the control cabinet looks more beautiful, and use safety is improved.
Description
Technical field
The utility model relates to electrostatic precipitator power supply control cubicle, and particularly a kind of radiator of electrostatic precipitator power supply control cubicle improves structure.
Background technology
Electrostatic precipitator has extensive use in large-scale filed of flue gas purification; Electrostatic precipitator comprises power supply control cubicle, rectifier transformer two big parts compositions; Wherein the power supply control cubicle is the core component of electrostatic precipitator; Its primary work loop principle is following: major loop comprises equipment major loop, operation control circuit and several sections such as auxiliary circuit such as cooling blower, exchanges the 380V power supply and connects through breaker of plastic casing, after the pressure regulation of reverse parallel connection SCR AC; It is elementary to deliver to rectifier transformer, again through boost, output direct current volt high pressure after the rectification.The signal that rectifier transformer high direct voltage side voltage sampling resistor and current sampling resistor take out is delivered to controller behind control cubicle gauge outfit, absorption interfered circuit; After via controller is handled; The control silicon controlled angle of flow after the modulation of pulse transformer, the control system of formation closed loop.
The size of electrostatic precipitator current/voltage output all is to open size by controllable silicon to realize, controllable silicon is the Primary Component of The whole control system, it reliable and stable be directly connected to that whole system moves normally whether.Because the electric current that controllable silicon passes through is all bigger, be a heat generating components, normal condition is all as shown in Figure 1 dispels the heat with the fan 03 that is contained in below the radiator through the radiator 02 that is installed in the control cubicle 01.But this radiator structure does not have independently air-supply passage; The air-flow that fan produces dispels easily; Radiating effect is not very desirable; In the abominable running environment of high temperature, be prone to cause and burn because of controllable silicon is overheated or out of service, exposed radiator is not only attractive in appearance but also cause potential safety hazard easily simultaneously.
The utility model content
The radiator that the utility model problem to be solved just provides a kind of electrostatic precipitator power supply control cubicle improves structure; Simple in structure, easy to make, not only increase the radiating effect of radiator; And make in the control cubicle appliance mounting panel back side more attractive in appearance, also improved safety in utilization.
In order to solve the problems of the technologies described above; The utility model adopts following technical scheme: the radiator of electrostatic precipitator power supply control cubicle improves structure; Comprise radiator that is located in the control cubicle and the fan that is located at the radiator below; It is characterized in that: the periphery of said radiator is provided with protective cover, and protective cover is fixed on the appliance mounting panel of control cubicle, the both ends open up and down of protective cover.
Further, the lower surface of said protective cover is lower than the installation site of fan.
Further, the upper surface of said protective cover is higher than the radiator upper surface.
Further, the cross section of said protective cover is corresponding with the shape of cross section of radiator.
Further, the cross section of said radiator is a rectangle, and the cross section of said protective cover is a rectangle frame.
Further, said radiator is fixed on the medial surface of protective cover, and the binding post of radiator passes protective cover from inside to outside, has the space between other parts of radiator and protective cover medial surface.
Further, be provided with insulation board between said radiator and the protective cover.
Further, said radiator comprises the last radiator and following radiator that distributes up and down, has the gap between last radiator and the following radiator.
After adopting technique scheme; The utlity model has following advantage: make the operating efficiency of fan be improved; The radiating effect of radiator is obviously promoted; And at a distance from relatively independent space, make in the control cubicle appliance mounting panel back side more attractive in appearance in radiator, also improved safety in utilization.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is the structural representation of the radiator of existing electrostatic precipitator power supply control cubicle;
Fig. 2 is the structural representation of a kind of embodiment of the utility model;
Fig. 3 be among Fig. 2 A-A to cutaway view;
Fig. 4 be among Fig. 2 B to view.
Embodiment
The structural representation of a kind of embodiment of the utility model shown in Fig. 2 to 4; The radiator of electrostatic precipitator power supply control cubicle improves structure; Comprise radiator 2 that is located in the control cubicle and the fan 3 that is located at the radiator below; The periphery of said radiator is provided with protective cover 4, and protective cover is fixed on the appliance mounting panel 11 of control cubicle, the both ends open up and down of protective cover.The cross section of protective cover is corresponding with the shape of cross section of radiator, and in the present embodiment, the cross section of radiator is a rectangle, and the cross section of said protective cover is a rectangle frame; Also can radiator be set to cylindrically, the protective cover relative set be a cylindrical shape.Requirement here, the lower surface of protective cover is lower than the installation site of fan; The upper surface of protective cover is higher than the radiator upper surface.The permeate gas stream whole protective roof that makes fan produce like this plays thermolysis to radiator, strengthens radiating effect.In the present embodiment, radiator comprises the last radiator 22 and following radiator 23 that distributes up and down, has the gap between last radiator and the following radiator, can further strengthen the radiating effect of radiator like this.
In the foregoing description, radiator is fixed on the medial surface of protective cover, and the binding post 21 of radiator passes protective cover from inside to outside, has the space between other parts of radiator and protective cover medial surface.Radiator directly is not fixed on the appliance mounting panel of control cubicle, reduces the influence of the heat of controllable silicon generation to other components and parts on the appliance mounting panel, and the air current flow that the space between radiator and the protective cover produces fan is more smooth and easy, improves radiating effect; Be provided with insulation board 5 in addition between radiator and the protective cover, protective cover can adopt metal to process like this, and specific heat capacity is low, heat conduction, rapid heat dissipation.
Except that above-mentioned preferred embodiment; The utility model also has other execution mode; Those skilled in the art can make various changes and distortion according to the utility model, only otherwise break away from the spirit of the utility model, all should belong to the defined scope of the utility model accompanying claims.
