Description

Technical Field

[0001] The invention relates to the technical field, in particular to an integrated variable frequency motor inverter provided with an alarm and automatic heat dissipation mechanism. Background Art

[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 working power frequency of the motor. There are many types of existing frequency converters, but there are still some shortcomings;

[0003] Publication No. CN210629341U discloses a frequency converter with an alarm function. During use, the device allows a gap between the frequency converter element and the inner bottom of the housing through a support frame structure, which facilitates the heat dissipation at the bottom of the frequency converter element. The temperature sensor and the current sensor transmit the detected temperature information and current information to the controller. When the temperature or current is not within the safe range, the controller controls the buzzer to work and sound an alarm, and at the same time the relay switch is closed to protect the frequency converter. The frequency converter can be stopped quickly, effectively protecting the frequency converter.

[0004] Publication number CN211880328U discloses a frequency converter with good heat dissipation performance. The device transfers the heat generated on the two side walls of the frequency converter body to the heat dissipation shell through the first heat dissipation plate, disperses the heat through the first heat dissipation net, and discharges the dispersed heat through the heat dissipation port, thereby completing the heat dissipation on both sides of the frequency converter body; the heat generated on the rear wall of the frequency converter body is transferred to the second heat dissipation net through the third heat dissipation plate, and the second heat dissipation net quickly transfers the heat to the second heat dissipation plate and the air. A plurality of ventilation holes are provided on the second heat dissipation plate. When the airflow passes through the second heat dissipation plate, due to the arc shape of the second heat dissipation plate, the airflow speeds on both sides of the second heat dissipation plate will be different, thereby forming a pressure difference, and the heat accumulated between the second heat dissipation plate and the rear wall of the frequency converter body is brought out, thereby completing the rapid heat dissipation of the frequency converter body.

[0005] However, there are still some shortcomings in the use of these two sets of inverters. During use, a certain high temperature will be generated inside, so a certain amount of heat dissipation is required. When external high temperature is required, the internal stability will be too high. The existing inverter cannot warn the staff well. After long-term use, the internal components will be damaged. At the same time, the existing inverter cannot clean its heat dissipation port well.

[0006] Therefore, we propose an integrated variable frequency motor inverter with alarm and automatic heat dissipation mechanism to solve the above problems. Summary of the invention

[0007] The object of the present invention is to provide an integrated variable frequency motor inverter with an alarm and automatic heat dissipation mechanism to solve the problem raised in the above background technology that the existing inverter will generate a certain high temperature inside during use, so it is necessary to perform a certain amount of heat dissipation inside.
