Problems solved by technology
[0003] Since the rectifier, smoothing circuit and inverter inside the frequency converter contain a large number of heating elements, the frequency converter will emit a lot of heat when it is working, and the normal operating temperature of the frequency converter is -10℃~+50℃. Once the heat cannot be discharged in time, it will easily affect the stability of the inverter and reduce the service life of the internal electronic components
The heat dissipation structure of the frequency converter in the prior art mostly adopts air-cooled heat dissipation, but the air-cooled heat dissipation can only dissipate heat from the front of the heating element, and the large amount of heat accumulated on the back of the heating element cannot be dissipated quickly, resulting in the heat dissipation of the entire heat dissipation structure. no significant effect

The invention discloses a self-heat-dissipation type frequency converter cabinet which comprises a cabinet body, a controller, a liquid pump and a radiator, an inner cavity of the cabinet body is filled with insulation type liquid heat exchange filler, and the feeding end and the discharging end of the radiator are connected with the discharging end and the feeding end of the cabinet body throughliquid pipes respectively; the liquid pump is located on a pipeline of one of the liquid pipes and electrically connected with the controller, the insulation type liquid heat exchange filler is transformation oil, the radiator comprises liquid collecting pipes and radiating pipes, a plurality of radiating connectors are arranged on one sides of the liquid collecting pipes, collecting covers are arranged on the other sides of the liquid collecting pipes, and collecting connectors are arranged in the middle of the collecting covers; the two ends of each heat dissipation pipe are detachably connected with the radiating connectors of the two adjacent liquid collecting pipes respectively, the collecting connectors of the two liquid collecting pipes are connected with the discharging end and thefeeding end of the cabinet body through the liquid pipes respectively, and it can be guaranteed that the frequency converter body is always located in a proper temperature range.
Description
【Technical field】 [0001] The invention relates to the technical field of frequency converters, in particular to the technical field of a self-radiating frequency converter cabinet. 【Background technique】 [0002] The frequency converter is a power control device that uses frequency conversion technology and microelectronics technology to control the AC motor by changing the frequency of the motor's working power supply. It is mainly composed of rectification, filtering, inverter, braking, driving, detection and micro-processing units. The core component of the frequency conversion speed regulation system. With the increasing degree of industrial automation, frequency converters are more and more widely used in industrial control and daily life. [0003] Since the rectifier, smoothing circuit and inverter inside the frequency converter contain a large number of heating elements, the frequency converter will emit a lot of heat when it is working, and the normal operating temp...
