Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of frequency converters, in particular to a frequency converter with moisture-proof and temperature-reducing functions. Background Art
[0002] The frequency converter is an electric power control device that applies frequency conversion technology and microelectronics technology to control AC motors by changing the frequency of the motor's working power supply. The frequency converter is mainly composed of rectification (AC to DC), filtering, inversion (DC to AC), braking unit, drive unit, detection unit, microprocessor unit, etc. The frequency converter adjusts the voltage and frequency of the output power supply by the internal IGBT's opening and closing, 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 protection, etc. With the continuous improvement of the degree of industrial automation, frequency converters have also been widely used. The frequency converters currently used cannot dissipate the heat generated by their own work during use, and the moisture accumulation on the surface will affect the use of the frequency converter.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0017] See also Figure 1-3 The utility model provides a frequency converter with moisture-proof and temperature-reducing functions, including a frequency converter body 1, a mounting plate 2 is fixedly installed on the rear side of the top of the frequency converter body 1, mounting holes 3 are opened on both sides of the front of the mounting plate 2, a protective shell 4 is sleeved on the back of the frequency converter body 1, inner heat dissipation holes 5 are opened on both sides of the frequency converter body 1, and outer heat dissipation holes 6 are opened on the outside of the protective shell 4, exhaust fans 7 are fixedly installed on both sides of the inner cavity of the protective shell 4, positioning plates 9 are fixedly installed on the back of both sides of the protective shell 4, and positioning holes 10 are opened on the upper and lower sides of the front of the positioning plate 9.
[0018] Through the above technical solution, by adding internal heat dissipation holes 5 on both sides of the inverter, the heat generated by the internal work can be dissipated outward, and it can also play a role in dissipating moisture. At the same time, the protective shell 4 outside the inverter can protect the outside and prevent dust and moisture. In addition, the external heat dissipation holes 6 and the exhaust fan 7 on the side can play a role in dissipating heat and moisture and ensure the normal operation of the inverter.
[0019] Front baffles 8 are fixedly mounted on both sides of the front side of the protective housing 4 , and the rear side of the inner end of the front baffle 8 is in contact with the surface of the inverter body 1 .
[0020] Through the above technical solution, the front baffle 8 can increase the firmness of the inverter body 1 after installation inside the protective shell 4, and can also limit the front end of the protective shell 4 to prevent the inverter from detaching from the inside of the protective shell 4.
[0021] Guide blocks 12 are fixedly mounted on both sides of the bottom of the inner cavity of the protective shell 4 , and the inner sides of the guide blocks 12 are in contact with the surface of the inverter body 1 .
[0022] Through the above technical solution, the guide block 12 can be used to limit and shield both sides of the lower end of the inverter body 1, and increase the firmness after installation inside the protective shell 4.
[0023] Rubber support pads 11 are fixedly installed in the middle of both sides of the inner cavity of the protective shell 4 , and the inner ends of the rubber support pads 11 are in contact with the outer side of the inverter body 1 .

[0027] The working principle of the utility model is: the frequency converter and the protective shell 4 can be installed and fixed in a suitable position by using the mounting plate 2 and the positioning plate 9. When the frequency converter generates heat when working for a long time, the internal heat will be discharged from the inner heat dissipation holes 5 on both sides, and the discharged heat will be accumulated inside the protective shell 4 and discharged through the outer heat dissipation holes 6, which can avoid excessive internal heat and moisture accumulation inside. At the same time, starting the exhaust fan 7 can discharge all the internal accumulated heat from the outer heat dissipation holes 6 and the front side, avoiding accumulation in the protective shell 4 and the inside of the frequency converter, thereby ensuring the normal use of the frequency converter.
