Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to electrical equipment technical field, concretely is a kind of energy-saving electric control cabinet. BACKGROUND
[0002] During the long-time operation of traditional electric control cabinet, the internal components of the electric control cabinet, especially the frequency converter with power of more than 90kw installed alone, will generate a large amount of heat. The existing heat dissipation scheme often relies on a single fan for exhaust, which is difficult to effectively control the temperature inside the cabinet and has high energy consumption. Some electric control cabinets are installed with air conditioners, but the air outlet of the air conditioner directly enters the inner cavity of the cabinet body of the electric control cabinet, which can only dissipate heat on the outer surface of the frequency converter. When the frequency converter is overloaded, the internal temperature of the frequency converter will be too high. The heat generated by the frequency converter and the cold air blown by the air conditioner cannot completely offset each other, resulting in that the heat of the frequency converter cannot be effectively dissipated, thereby affecting the performance and service life of the frequency converter. SUMMARY
[0003] The utility model aims at overcoming the defects of prior art, and provides an energy-saving electric control cabinet. By arranging an air inlet and an air outlet duct in the cabinet body, the air of the air conditioner is introduced into the frequency converter, so that efficient heat dissipation of the frequency converter is realized, and energy-saving effect is achieved.
[0004] The utility model is implemented by the following technical solutions:
[0005] An energy-saving electric control cabinet includes a cabinet body with a frequency converter arranged therein, and an air conditioner arranged outside the cabinet body. The frequency converter includes a frequency converter shell. A heat dissipation air inlet is arranged at a position close to the bottom of one side of the frequency converter shell. A heat dissipation air outlet is arranged at the top of the frequency converter shell. An air outlet fan is arranged at the air outlet of the top of the cabinet body. The heat dissipation air inlet of the frequency converter shell is connected in communication with the air outlet of the air conditioner through an air inlet duct. The heat dissipation air outlet of the frequency converter shell is connected in communication with the air outlet of the top of the cabinet body through an air outlet duct.
[0006] As a preferred scheme of the above-mentioned energy-saving electric control cabinet, a first filter screen is arranged at the air outlet of the top of the cabinet body, and the first filter screen is arranged below the air outlet fan.
[0007] As a preferred scheme of the above-mentioned energy-saving electric control cabinet, a perforation is arranged on one side of the cabinet body. The air inlet duct extends out of the cabinet body through the perforation and is connected in communication with the air outlet of the air conditioner. A second filter screen is arranged at the air outlet of the air conditioner.
[0008] Compared with the prior art, the utility model has the following advantages:
[0009] This utility model provides an energy-saving electrical control cabinet. By opening a heat dissipation air inlet and a heat dissipation air outlet on the inverter housing, and connecting the heat dissipation air inlet to the air conditioner outlet through an air inlet duct, and leading the hot air discharged from the heat dissipation air outlet out of the cabinet through an air outlet duct, the heat inside the inverter is efficiently discharged in conjunction with the exhaust fan, reducing unnecessary energy consumption.

[0013] The embodiments of this utility model are described in detail below. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific operation processes. However, the protection scope of this utility model is not limited to the following embodiments.
[0014] See Figure 1 and Figure 2 This embodiment discloses an energy-saving electrical control cabinet, including a cabinet 1 housing an internal frequency converter, an externally mounted air conditioner 2 on the outside of the cabinet 1, and a frequency converter housing 3. A cooling air inlet 4 is located near the bottom of one side of the frequency converter housing 3, and a cooling air outlet 5 is located at the top of the frequency converter housing 3. A first filter 8 and an exhaust fan 7 are located at the air outlet 6 at the top of the cabinet 1, with the first filter 8 positioned below the exhaust fan 7. The cooling air inlet 4 of the frequency converter housing 3 is connected to the air outlet of the air conditioner 2 via an air inlet duct 9, and the cooling air outlet 5 of the frequency converter housing 3 is connected to the air outlet 6 at the top of the cabinet 1 via an air outlet duct 10. A perforation is provided on one side of the cabinet 1, through which the air inlet duct 9 extends outside the cabinet 1 and connects to the air outlet of the air conditioner 2. A second filter is located at the air outlet of the air conditioner 2. The first filter 8 and the second filter filter filter external dust, protecting the components inside the cabinet 1.
[0015] When the electric control cabinet works, the externally hung air conditioner 2 is started, the cold air generated by the air conditioner 2 is directly introduced into the inside of the frequency converter shell 3 through the air inlet air duct 9, and the inside of the frequency converter is effectively cooled. The heat generated by the frequency converter when the frequency converter runs is discharged from the top heat dissipation air outlet 5 by the self-provided axial flow fan, then is introduced into the air outlet fan 7 through the air outlet air duct 10, and finally is discharged out of the cabinet body 1 of the electric control cabinet. Since the cold air of the air conditioner 2 is directly introduced into the inside of the frequency converter and directly cools and dissipates heat in the inside of the frequency converter, the efficient discharge of the heat in the inside of the frequency converter is ensured, and unnecessary energy consumption is reduced, compared with the traditional heat dissipation structure, the energy use efficiency is significantly improved in this structure form.
[0016] The above is only a preferred embodiment of the present application, and is not intended to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
