A high temperature adaptable inverter

Abstract

The invention discloses a high temperature adaptable frequency converter, belonging to the field of frequency converters. A high temperature adaptable frequency converter comprises an adaptable frequency converter body. An air inlet baffle is fixedly connected to the left end of the adaptable frequency converter body, and the air intake temperature is sensed. The right inner wall of the groove is provided with a plurality of air inlet holes which are connected to the inside of the adaptable inverter body. Through the cooperation of the flexible diameter-adjusting hollow sleeve, the temperature-sensing outer sheath, the temperature-sensing heat-collecting strip and the heat-shrinkable mesh, the The air inlet hole of the adaptable inverter body is adjustable, so that it can maintain the dustproof and air intake function when the adaptable inverter body is normally dissipating heat, and can also increase the diameter by expanding the diameter when the adaptable inverter body is overheated. The air flow in the large adaptable inverter body can effectively improve the heat dissipation effect of the adaptable inverter body, and at the same time improve the adaptability of the adaptable inverter body to high temperature, it can also reduce the energy consumption of the inverter and improve its environmental protection and energy saving. nature.

Description

technical field [0001] The present invention relates to the field of frequency converters, and more particularly, to a high temperature adaptable frequency converter. Background technique [0002] The inverter is mainly composed of rectification (AC to DC), filtering, inverter (DC to AC), braking unit, drive unit, detection unit and micro-processing unit. The inverter adjusts the voltage and frequency of the output power supply by switching on and 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 inverter also has many protection functions. , such as overcurrent, overvoltage, overload protection, etc. With the continuous improvement of industrial automation, frequency converters have also been widely used. [0003] The energy saving of the frequency converter is mainly manifested in the application of fans and water pumps. A...

Problems solved by technology

[0004] When the inverter is overheated due to the influence of the external environment or high working intensity, the heat dissipation effect of the inverter will become poor, and because the size of the air inlet hole of the inverter is constant, the air exchange volume inside the inverter does not change much. Furthermore, the method of increasing the heat dissipation power of the above-mentioned heat dissipation means cannot achieve an effective heat dissipation effect, and will also increase the energy consumption of the frequency converter and reduce its environmental protection and energy saving properties.
