Description
Technical field
The utility model relates to a kind of frequency converter, relates in particular to a kind of radiating structure of frequency converter.
Background technology
Frequency converter is one of modern electrical machine speed regulating control and energy-conservation indispensable important devices, very extensive in the application of industrial circle.Main circuit of converter is comprised of rectification circuit, intermediate circuit, inverter circuit three parts; power device caloric value in these circuit is larger in the course of the work; if can not will make frequency converter shut down or damage because of excess Temperature to its efficiently radiates heat, can not normally move.
In please number be 200920316261.9 utility model patent " frequency converter built-in wind cooling radiator structure ", it discloses in the lower house of frequency converter fixedly fixedly aluminum alloy heat sink of radiator fan, middle part.But it is large that this technical scheme exists the radiator volume, the shortcoming that weight is large, this does not meet the development trend that product is light, little, sometimes because radiator causes greatly product cost, is difficult to reduce yet.
The utility model content
For the prior art above shortcomings, the purpose of this utility model just is to provide a kind of radiating structure of frequency converter, simple in structure, good heat dissipation effect, can effectively guarantee the stable operation of frequency converter, improve the reliability of frequency converter, thereby extend frequency converter useful life.
To achieve these goals, the technical solution adopted in the utility model is such: a kind of radiating structure of frequency converter, comprise upper shell, lower house, converter circuit plate, radiator and radiator fan, it is characterized in that: the both sides relative with lower house at upper shell are provided with ventilating opening, and described radiator comprises heat-conducting plate and some fin that is arranged at heat-conducting plate one side; Described converter circuit plate is arranged on lower house by radiator, and has gap between the both sides of the both sides of radiator and lower house, and this converter circuit plate and fin lay respectively in upper shell and lower house; Described fin be arranged in parallel, makes to form air channel between adjacent two fin, and the two ends in described air channel are corresponding with two ventilating openings on lower house respectively; Described radiator fan is installed on the ventilating opening place of lower house one side, and radiator fan overlaps at least partly with fin.
Further, described fin extends to the lower house bottom.
Further, described heat-conducting plate and fin are made by aluminum alloy materials.
Further, described upper shell and lower house are connected together by screw.
Compared with prior art, the utility model has the advantage of: simple in structure, good heat dissipation effect, can guarantee the stable operation of frequency converter effectively, improves the reliability of frequency converter, thereby extend frequency converter useful life.
The accompanying drawing explanation
The structural representation of Fig. 1 after to be the utility model vertically cut upper shell and lower house open.
In figure: 1-upper shell, 2-lower house, 3-converter circuit plate, 4-radiator fan, 5-heat-conducting plate, 6-fin, 7-ventilating opening.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment: referring to Fig. 1, a kind of radiating structure of frequency converter, comprise upper shell 1, lower house 2, converter circuit plate 3, radiator and radiator fan 4.Be integrated with frequency changer circuit on described converter circuit plate 3, and some power components, electric capacity, IGBT pipe etc. are installed.The both sides relative with lower house 2 at upper shell 1 are provided with ventilating opening 7.Described upper shell 1 is connected together by screw with lower house 2; Easy accessibility, the dismounting of the radiator fan 4 of being more convenient for, radiator and converter circuit plate 3.
Described radiator comprises heat-conducting plate 5 and some fin 6 that is arranged at heat-conducting plate 5 one sides; Described heat-conducting plate 5 is made by aluminum alloy materials with fin 6, and heat-conducting plate 5 is one-body molded, so not only easy to process with fin 6, and radiating effect is better.Described converter circuit plate 3 is arranged on lower house 2 by radiator, and has gap between the both sides of the both sides of radiator and lower house 2, and this converter circuit plate 3 and fin 6 lay respectively in upper shell 1 and lower house 2; Described fin 6 be arranged in parallel, makes to form air channel between adjacent two fin 6, and the two ends in described air channel are corresponding with two ventilating openings 7 on lower house 2 respectively; Described radiator fan 4 is installed on ventilating opening 7 places of lower house 2 one sides, and radiator fan 4 overlaps at least partly with fin 6.During concrete enforcement, described fin 6 extends to lower house 2 bottoms; Can further improve radiating efficiency.
The heat produced while by radiator, the components and parts on converter circuit plate 3 being worked guides and is dispersed in air, and by radiator fan 4, heat is discharged in frequency converter shell, due to radiator fan 4 between air channel and ventilating opening 7, therefore when fan work, air-flow can pass from lower house 2 smoothly and rapidly, thereby takes away heat rapidly.Simultaneously, there is gap between radiator and lower house 2, thereby make radiator fan 4 in the course of the work, the air-flow passed from lower house 2 forms negative pressure, thereby take away the heat in upper shell 1, thereby can improve further radiating effect, and then effectively guarantee the stable operation of frequency converter, improve the reliability of frequency converter, thereby extend frequency converter useful life.
Finally it should be noted that, above embodiment is only in order to the technical solution of the utility model to be described but not the restriction technologies scheme, those of ordinary skill in the art is to be understood that, those are modified to the technical solution of the utility model or are equal to replacement, and do not break away from aim and the scope of the technical program, all should be encompassed in the middle of claim scope of the present utility model.
