The structure comprises a bottom plate, two parallel slidinggrooves are symmetrically arranged on the bottom plate, each sliding groove is internally provided with one sliding block, one side, upwards leaving away from one sliding groove, of each sliding blockis provided with one transition plate, one side, far away from a body, of the bottom plate is provided with a first heat radiation plate, one side, symmetrical with the first heat radiation plate, ofthe bottom plate is provided with a second heat radiation plate, the bottom portion of the second heat radiation plate is provided with a connection plate, the connection plate is provided with a through hole, one side, close to the body, of the bottom plate is provided with a fixed plate, the fixed plate is provided with a screwing rod matching with the through hole, one end, far away from the body, of the screwing rod passes through the through hole and is provided with a push plate, one end of the transition plate is provided with a third heat radiation plate which is internally provided with mineral oil for heat radiation, and one side of the third heat radiation plate is provided with an auxiliary heat radiation plate. The frequency converter heat radiation structure can reduce the temperature of the frequency converter, can reduce noise, can reduce environmental pollution, can reduce potential safety hazards, can be convenient for maintenance operation of the frequency converter, and is convenient to use and good in effect.

Description

technical field [0001] The invention relates to the field of heat dissipation devices, in particular to a frequency converter heat dissipation structure. 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 the core component of the frequency conversion speed regulation system. As the degree of industrial automation is getting higher and higher, frequency converters are more and more widely used in the fields of industrial control and daily life. Since the core circuit module of the inverter has the characteristics of high integration, high frequency, high voltage, and high speed, the loss of power devices in the main circuit will generate heat, which will cause serious heat generation during operation and affect the working effect of the inverter. If it works under abnormal temperat...

Problems solved by technology

The air heat dissipation method has a slow heat dissipation speed, and the effect is not good when the temperature is high and needs to be cooled quickly; the air cooling heat dissipation method is slow in heat dissipation speed, and the greater the wind speed, the greater the noise, which will affect the environment; the water cooling method is adopted. The method of heat dissipation allows the water to take away the heat of the metal sealed box during the passage of the water channel, but it is necessary to completely eliminate the occurrence of water leakage during use, which has certain safety hazards; the method of oil cooling and heat dissipation will The inverter is soaked in mineral oil, and the heat dissipation effect is better, but because the inverter is soaked in oil, when it needs to be taken out for inspection and other operations, the oil will cover the inverter, which is inconvenient to operate, and the removal of oil will increase the workload and reduce work efficiency
