The invention discloses a frequency converter heat-dissipation cooling system and a controlling method and a device of the frequency converter heat-dissipation cooling system. The controlling method of the frequency converter heat-dissipation cooling system comprises steps as below: detecting a first temperature, wherein the first temperature is the temperature of the inversion, and rectifying module heat dissipation piece of the frequency converter at a first moment; judging whether the first temperature is larger than a pre-set temperature; when the first temperature is larger than the pre-set temperature, a valve is controlled to be opened, otherwise the value is controlled to be closed, wherein when the valve is in an opened state, cooling media circulate inside the frequency converter heat-dissipation cooling system, when the valve is in an closed state, the cooling media are still inside the frequency converter heat-dissipation cooling system. The frequency converter heat-dissipation cooling system and the controlling device and the method of the frequency converter heat-dissipation cooling system are capable of detecting the temperature of the inversion and rectifying module heat dissipation piece, when the temperature exceeds the pre-set safe temperature, the cooling media are controlled to circulate inside the heat-dissipation cooling system, and therefore the frequency converter is enabled to be better in heat-dissipation cooling effect.
Description
technical field [0001] The invention relates to the field of frequency converters, in particular to a heat dissipation and cooling system for frequency converters and a control method and device thereof. Background technique [0002] The inverter and rectifier modules of the centrifuge frequency converter need real-time heat dissipation. At present, the air cooling and water cooling methods are often used to achieve the heat dissipation effect. However, the heat dissipation and cooling effects of air cooling and water cooling are not ideal, and it cannot guarantee that the inverter and rectifier modules work in a safe state all the time. [0003] Aiming at the problem of poor heat dissipation and cooling effect of the frequency converter in the related art, no effective solution has been proposed yet. Contents of the invention [0004] The main purpose of the present invention is to provide a frequency converter cooling system and its control method and device, so as to s...
