As shown in fig. 1 and 2, an embodiment of the present utility model discloses a frequency converter including a cabinet 300, a reactor 800, and a reactor mounting sheet metal 700. The reactor installation metal plate 700 is fixed on the back plate 307 of the cabinet 300, and a reactor installation cavity 701 is formed between the reactor installation metal plate 700 and the back plate 307 of the cabinet 300, and it should be noted that the reactor installation cavity 701 needs to be communicated with the cavity of the cabinet 300, so as to ensure free circulation of air, so as to take away heat in the reactor installation cavity 701. The reactor installation cavity 701 may not be communicated with the cavity of the cabinet 300, and an air inlet communicated with the outside of the cabinet 300 may be formed on the back plate 307 to form an effective heat dissipation air channel.
The reactor 800 is disposed in the reactor mounting cavity 701, specifically, the reactor 800 may be fixed on the reactor mounting sheet metal 700 or on the back plate 307 of the cabinet 300, and the fixing position of the reactor 800 is not limited in this embodiment, so long as the reactor is disposed in the reactor mounting cavity 701.
As shown in fig. 3 and fig. 307 of the cabinet 300 is provided with a reactor installation cavity air outlet 306 which is communicated with the reactor installation cavity 701, and a reactor installation cavity heat dissipation fan is provided at the reactor installation cavity air outlet 306, it should be noted that the position of the reactor installation cavity air outlet 306 may be at the same height as the reactor 800 or higher than the reactor 800. As will be appreciated by those skilled in the art, to achieve heat dissipation, the reactor installation cavity 701 is not a closed cavity, and with the provision of the reactor installation cavity air outlet 306, the reactor installation cavity 701 needs to have a corresponding installation cavity air inlet, at least one of which should be disposed on the underside of the reactor 800, so that heat dissipation air flows from the installation cavity air inlet into the reactor installation cavity 701 and through the reactor 800, and then is discharged from the reactor installation cavity air outlet 306 to the reactor installation cavity 701.
The cabinet 300 is provided with an air inlet communicated with the cavity of the cabinet 300, and the air flow entering the reactor installation cavity 701 from the installation cavity air inlet is derived from the cavity of the cabinet, so that the cabinet 300 is required to be provided with a corresponding air inlet, so that external air can enter the cabinet 300. Specifically, the air inlet at least includes a first air inlet 301 and a second air inlet 302 respectively disposed at two sides of the bottom of the cabinet 300.
According to the frequency converter provided by the utility model, the reactor installation metal plate 700 is fixed on the back plate 307 of the cabinet 300, so that the reactor installation cavity 701 is formed, and the reactor 800 is arranged in the reactor installation cavity 701. The back plate 307 of the cabinet 300 is provided with the reactor installation cavity air outlet 306, and the reactor installation cavity air outlet 306 is provided with the reactor installation cavity air-cooling fan, so that the reactor installation cavity 701 forms an independent air channel under the action of the reactor installation cavity air-cooling fan, heat generated by the reactor is discharged through the reactor installation cavity air outlet 306, heat generated by the reactor 800 is not diffused to other parts in the cabinet 300, and heat dissipation of other parts is not affected.
As shown in fig. 4, in this embodiment, the reactor installation sheet metal 700 has a box structure with an opening, and the opening side of the reactor installation sheet metal 700 is provided with a fixing flange 702 that is bent outwards, that is, the fixing flange 702 is bent towards the outer side of the cavity of the box, and the fixing flange 702 is attached to the back plate 307 of the cabinet 300 and is fixed by a fastener. The fixing flange 702 may be provided with fastening holes through which fasteners may pass to facilitate fixing with the back plate 307 of the cabinet 300. It should be noted that, a portion of the structure in the reactor mounting cavity 701 needs to extend to the outside of the reactor mounting cavity 701, and a notch 704 may be disposed at a corresponding position of the reactor mounting sheet metal 700, so that the structure having the overhanging requirement may extend out of the reactor mounting cavity 701.
The reactor installation sheet metal 700 is provided with at least one reactor installation cavity air inlet communicated with the reactor installation cavity 701, and the reactor 800 is arranged on a heat dissipation path between the reactor installation cavity air inlet and the reactor installation cavity air outlet 306. In order to give out a larger installation space for the reactor 800 to facilitate the arrangement of the reactor 800, at least one reactor installation cavity air inlet may be arranged on the lower side of the reactor installation sheet metal 700 in the height direction, while the reactor installation cavity air outlet 306 is arranged at a position slightly higher than the reactor installation cavity 701.
It should be noted that, the reactor installation cavity air inlet may be formed by a lower side wall plate without a box structure, or may be formed by a way of opening a hole in the lower side wall plate of the box structure, so long as the effective flow of the air current can be realized. In addition, the notch 704 can also realize effective air intake to improve heat exchange efficiency.
The wallboard opposite to the opening side of the reactor mounting sheet metal 700 is a reactor mounting backboard 703, the reactor mounting backboard 703 is of a rectangular structure, two sides extending along the height direction of the reactor mounting backboard 703 are connected with reactor mounting side plates 705, the side at the top of the reactor mounting backboard is connected with a reactor mounting top plate 706, and one sides, far away from the reactor mounting backboard 703, of the reactor mounting side plates 705 and the reactor mounting top plate 706 are bent to form a fixing folded edge 702. The reactor installation sheet metal 700 can be of an integral bending structure, and can also be formed by connecting and assembling a plurality of plate bodies.
The size of the reactor 800 is not large, and it does not occupy the entire size of the cabinet 300 in the front-rear direction, in this embodiment, in order to improve the space utilization, a first electronic component having a smaller influence on heat generation may be mounted on a side of the reactor mounting back plate 703 opposite to the reactor mounting cavity 701, and the heat generation amount of the first electronic component is smaller than that of the reactor 800. Since the heat generation amount of the first electronic component itself is smaller than that of the reactor 800, the heat dissipation of the reactor 800 is not affected by mounting the first electronic component on the reactor mounting back plate 703. In addition, the first electronic component has less influence on heat generation, and the reactor 800 with larger heat generation does not influence the effectiveness and safety of the first electronic component.
In this embodiment, the first electronic component may include at least one of the circuit breaker 600, the input copper bar 400, and the wire-in-ground copper bar 500. The heat productivity of the circuit breaker 600, the input copper bar 400 and the wire-incoming grounding copper bar 500 is smaller than that of the reactor 800, and the effective heat dissipation of the reactor 800 is not affected by fixing all the three on the reactor mounting backboard 703. The influence of the reactor 800 on the circuit breaker 600, the input copper bar 400 and the incoming line grounding copper bar 500 is small, and the circuit breaker 600 itself needs to be fixed, so that at least one of the circuit breaker 600, the input copper bar 400 and the incoming line grounding copper bar 500 is mounted on the reactor mounting backboard 703, and the space utilization rate of the cabinet 300 is improved on the premise that the normal use of each device is not affected.
In addition, a second electronic component with a larger heat productivity than the first electronic component can be further arranged in the reactor mounting cavity 701, the heat productivity of the second electronic component is smaller than that of the reactor 800, and the reactor 800 and the second electronic component are arranged from low heat productivity to high heat productivity along the heat dissipation path of the reactor mounting cavity 701. Since there is a reliable and independent heat dissipation air duct for the reactor mounting chamber 701 and the reactor mounting chamber 701 is not fully occupied by the reactor 800, in this embodiment, in order to effectively utilize the reactor mounting chamber 701, a second electronic component is disposed in the reactor mounting chamber 701 in addition to the reactor 800.
The heat productivity of the second electronic component is smaller than that of the reactor 800, and the reactor 800 can be arranged at the downstream of the second electronic component along the heat dissipation path, so that the reactor 800 with larger heat productivity is prevented from influencing the effective heat dissipation of the second electronic component. The second electronic component is arranged upstream of the reactor 800 such that heat generated by the reactor 800 does not flow through the second electronic component.
In the present embodiment, the second electronic component may include at least one of the contactor 900 and the charging resistor 1000, so as to further improve the space utilization. It should be noted that, the contactor 900 and the charging resistor 1000 may be disposed below the reactor 800, the air outlet 306 of the reactor installation cavity is located above the reactor 800, and the heat productivity of the contactor 900 and the charging resistor 1000 is smaller than that of the reactor 800, so that the contactor 900 and the charging resistor 1000 are disposed below the reactor 800, so that the reactor 800 with a larger heat productivity is located downstream of the heat dissipation air flow, and excessive heat is prevented from flowing through the contactor 900 and the charging resistor 1000, thereby affecting the performance and the service life of the contactor 900 and the charging resistor 1000.
The independent air duct enclosed by the reactor mounting sheet metal 700 not only realizes effective heat dissipation of the reactor 800 and prevents heat of the reactor 800 from flowing into other spaces to affect other devices, but also can fully utilize the reactor mounting sheet metal 700 and improve the space utilization rate.
As shown in fig. 1, in an embodiment of the present utility model, a third electronic component is disposed in the cabinet 300, and the reactor mounting sheet metal 700 and the third electronic component are sequentially disposed along the width direction of the cabinet 300. So that the cabinet 300 is configured as at least two installation spaces in the width direction. One of the installation spaces is at least used for arranging the reactor installation sheet metal 700, the reactor 800 and the second electronic component in the reactor installation cavity 701, and the like. The other installation space is used at least for arranging a third electronic component. By the arrangement, devices in the cabinet 300 can be more conveniently arranged, and the space utilization rate is improved.
It should be noted that the third electronic component at least includes at least one of the power module 200 and the dc bus capacitor module 100. The power module 200 may be disposed below the dc bus capacitor module 100.
It should be noted that, to increase the integration of the modules, the dc bus capacitor module 100 and the power module 200 may be integrally mounted on a riser (not shown in the drawings), and then the riser is integrally mounted in the cabinet 300. During maintenance, the vertical plate can be removed from the cabinet 300, and only the corresponding module on the vertical plate can be removed.
The cabinet 300 is provided with an air-out heat dissipation device and a third air inlet 303 for dissipating heat of a third electronic component (for example, the dc bus capacitor module 100) on a side wall (in the embodiment, the right side wall of the cabinet 300) on which the third electronic component is disposed (for example, the dc bus capacitor module 100), so as to form a heat dissipation path for dissipating heat of the third electronic component, and the third air inlet 303 may be disposed on a lower side of the air-out heat dissipation device.
Because the heat productivity of the dc bus capacitor module 100 is large, two air-out heat dissipation devices, namely the first air-out heat dissipation device 304 and the second air-out heat dissipation device 305, may be disposed here, and each air-out heat dissipation device includes an air outlet and a heat dissipation fan disposed at the air outlet. It should be noted that the number of the air-out heat dissipation devices is not limited to one or two, and those skilled in the art can design according to the requirements to ensure that the effective heat dissipation requirements can be provided for the dc bus capacitor module 100 and other devices in the cabinet 300.
The cabinet 300 provides a corresponding heat dissipation duct for the dc bus capacitor module 100, and dissipates heat through two air-out heat dissipation devices on the right side. Under the condition that the heat dissipation effect is not considered, the independent air duct of the reactor 800 can be combined with the air duct of the direct current bus capacitor module 100, namely, the right side of the reactor mounting cavity 701 is opened, and the heat dissipation of the reactor 800 is realized by means of the two air-out heat dissipation devices of the direct current bus capacitor module 100. It should be noted that, the heat generated by the reactor 800 is great, and the heat will affect the dc bus capacitor module 100 in the rear air duct, so as to affect the heat dissipation of the dc bus capacitor module 100, and shorten the life of the dc bus capacitor module 100, which is not beneficial to the reliability of the frequency converter, so that in the above embodiment of the utility model, an independent heat dissipation air duct is designed for the reactor 800.
