Description

Technical Field

[0001] The present invention relates to the technical field of containerized frequency converters, and particularly to a containerized frequency converter with an embedded heat dissipation device. Background Art

[0002] With the improvement of industrial automation, as a power control device, the frequency converter realizes energy saving and speed regulation by changing the working power frequency of the motor, and is widely used in electric drive equipment in energy industries such as petroleum and shale gas. However, the high integration of the core circuit module of the frequency converter and its characteristics of high-frequency, high-voltage and high-speed operation result in serious heat generation. The normal operating temperature range is -10°C to +50°C. Beyond this range, the performance of electronic components will be affected. Working at an over-temperature for a long time will even shorten the equipment life or cause serious consequences such as explosion and burning.

[0003] There are many problems with the traditional heat dissipation methods of frequency converters. Currently, it is common to cover the heat dissipation substrate on the rear side of the frequency converter body with heat dissipation fins, but the heat dissipation effect is not good, and the frequency converter is still likely to exceed the normal operating temperature. Moreover, when some frequency converters use radiators, they generally directly fix the radiator outside and connect it to the frequency converter through pipelines. This not only increases the site occupation, but also the drive cables and coolant pipelines between the radiator and the frequency converter are scattered outside, and there is also a risk of being damaged by falling objects. Therefore, the present application provides a containerized frequency converter with an embedded heat dissipation device to meet the needs. Summary of the Invention

The water cooling component 6 includes a water cooling box 601, a first side cooling pipeline 602, a second side cooling pipeline 603 and a third side cooling pipeline 604. The first side cooling pipeline 602, the second side cooling pipeline 603 and the third side cooling pipeline 604 are all formed by connecting a plurality of pipes in series. The first side cooling pipeline 602, the second side cooling pipeline 603 and the third side cooling pipeline 604 are all located in the installation inner cavity 107, and the first side cooling pipeline 602, the second side cooling pipeline 603 and the third side cooling pipeline 604 are interconnected. The water cooling box 601 is located on the upper surface of the partition board between the placement cavity 106 and the installation cavity 109. A circulation pump 606 is arranged on the upper surface of the partition board outside the water cooling box 601. The water outlet of the circulation pump 606 is connected to the first side cooling pipeline 602, and the water inlet of the circulation pump 606 is connected to the third side cooling pipeline 604. A water outlet pipe 615 and a water return pipe 614 are arranged between the circulation pump 606 and the water cooling box 601. The water outlet pipe 615 and the water return pipe 614 both pass through the water cooling box 601 and extend into the water cooling box 601. A water adding pipe 605 is arranged at the top of the water cooling box 601. One end of the water adding pipe 605 is located inside the water cooling box 601, and the other end of the water adding pipe 605 passes through the side wall of the frequency converter box body 101 and extends outside the frequency converter box body 101.

A plurality of water flowing holes 613 are formed on the surface of the heat conducting plate 612.

[0027] It should be further noted in this embodiment that, second, the cooling water in the water cooling box 601 is pumped out by the circulation pump 606 and enters the first side cooling pipeline 602 through the water outlet pipe 615 to adsorb the heat dissipated by the inverter core circuit module installed in the placement cavity 106. After the first side cooling pipeline 602 absorbs the heat, the cooling water is injected into the third side cooling pipeline 604 through a pipeline. The third side cooling pipeline 604 further adsorbs the heat dissipated by the inverter core circuit module installed in the placement cavity 106. After the adsorption is completed, the cooling water in the third side cooling pipeline 604 enters the second side cooling pipeline 603 through a pipeline and adsorbs the heat dissipated by the inverter core circuit module installed in the placement cavity 106 again. Through three times of adsorption, the heat dissipated by the inverter core circuit module installed in the placement cavity 106 is fully absorbed, improving the heat dissipation effect of the device. The cooling water after adsorbing the heat enters the water return pipe 614 through the circulation pump 606 and then enters the water cooling box 601, where it falls into the water return bin 607 inside the water cooling box 601. Then, the heat in the cooling water is guided by the heat conduction plate 612. The water flow flows out through the water flow holes 613 on the surface of the heat conduction plate 612 and enters the water injection bin 608 through the connection groove 610. The heat adsorbed by the heat conduction plate 612 is taken away by the air flow brought by the cooling fan 307, thereby reducing the heat of the cooling water and enabling the cooling water to circulate and adsorb the heat dissipated by the inverter core circuit module installed in the placement cavity 106, further improving the heat dissipation effect of the device.

[0028] Working principle By starting the cooling fan 307, a negative pressure is generated in the installation cavity 109. The outside air enters the housing through the air intake slots 402 on the surface of the housing and is filtered by the second filter screen 403 to prevent impurities in the outside air from entering the interior of the device. The filtered air enters the installation inner cavity 107, taking away the heat not absorbed by the side cooling pipeline, so that the hot air is discharged through the first filter screen 105, thereby improving the heat dissipation effect of the device. The second filter screen 403 can be pulled out of the housing through the handle 404 for replacement. The cooling water in the water cooling tank 601 is pumped out by the circulation pump 606 and enters the first side cooling pipeline 602 through the water outlet pipe 615 to adsorb the heat dissipated by the inverter core circuit module installed in the placement cavity 106. After the first side cooling pipeline 602 absorbs the heat, the cooling water is injected into the third side cooling pipeline 604 through a pipeline. The third side cooling pipeline 604 further adsorbs the heat dissipated by the inverter core circuit module installed in the placement cavity 106. After the adsorption is completed, the cooling water in the third side cooling pipeline 604 enters the second side cooling pipeline 603 through a pipeline and adsorbs the heat dissipated by the inverter core circuit module installed in the placement cavity 106 again. Through three times of adsorption, the heat dissipated by the inverter core circuit module installed in the placement cavity 106 is fully absorbed. The cooling water after adsorbing the heat enters the return water pipe 614 through the circulation pump 606 and then enters the water cooling tank 601, falling into the return water bin 607 inside the water cooling tank 601. Then, the heat in the cooling water is guided by the heat conducting plate 612. The water flows out through the water flow holes 613 on the surface of the heat conducting plate 612 and enters the water injection bin 608 through the connection slot 610. The heat adsorbed by the heat conducting plate 612 is taken away by the air flow brought by the cooling fan 307, thereby reducing the heat of the cooling water and enabling the cooling water to circulate to adsorb the heat dissipated by the inverter core circuit module installed in the placement cavity 106.

[0029] The technical solution provided by the present invention embeds the heat dissipation components into the box body of the inverter, without occupying additional site space.
