Embodiment Construction
[0030] The present invention will be further described below in conjunction with the embodiments of the present invention.
[0031] Please refer to Figure 1-8 , embodiment one:
[0032] The invention discloses a cooling system and method for adjusting a frequency converter, the steps of which are as follows:
[0033] Step 1: Set the minimum operating temperature limit and the maximum temperature limit of the cooling device, and also need to set the maximum and minimum operating frequency of the inverter's voltage ripple;
[0034] Step 2: Check the inside of the inverter through the sensor center. First, use the temperature sensor to monitor the internal temperature of the inverter, and upload the temperature data in time. At the same time, it is necessary to receive the voltage pulse frequency during the working process of the inverter, and Upload frequency results;
[0035] Step 3: Receive the result, and display the result data synchronously in the display module to faci...

The invention discloses an adjusting heat dissipation system and method of a frequency converter. The system comprises an adjusting center, a frequency converter, a wave frequency generation module and a temperature sampling module. The adjusting center is in bidirectional signal connection with the frequency converter through wireless optical fiber communication, and the output end of the frequency converter is connected with the input end of the wave frequency generation module and the input end of the temperature sampling module. According to the adjusting heat dissipation system and method of the frequency converter, firstly, the appearance of the frequency converter is limited, two installation fans are arranged at the rear end, the installation fans can be clamped in a protection shell as needed and run in time during operation of the system to improve the cooling efficiency of the system; the back of an adjustment and control backboard is hollowed out, so that the heat dissipation efficiency in the frequency converter is improved; a cooling air duct can tighten the hot air and then discharge the hot air from the other port in the use process, the temperature of the hot air can be reduced, and the heat dissipation efficiency is improved; and the shell of the whole frequency converter can be quickly disassembled and assembled.
Description
technical field [0001] The invention relates to the technical field of frequency converters, in particular to an adjustable cooling system and method for frequency converters. 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. The frequency converter is mainly composed of rectification (AC to DC), filter, inverter (DC to AC), braking unit, drive unit, detection unit, micro-processing unit, etc. The frequency converter adjusts the voltage and frequency of the output power supply by switching off the internal IGBT, and provides the required power supply voltage according to the actual needs of the motor, thereby achieving the purpose of energy saving and speed regulation. In addition, the frequency converter has many protection functions , such as overcurrent, overvoltage, overload protect...
