Abstract

A frequency converter with an automatic temperature control and heat radiation function comprises a control cabinet, a cooling device, a cooling device controller, a temperature sensor and an axial flow fan. Through temperature detection of the temperature sensor to the frequency converter, the temperature sensor transmits information to the cooling device controller. The cooling device controller starts the cooling device for cooling air which enters the frequency converter, thereby performing a better heat radiation function, ensuring normal operation of the frequency converter, preventing component damage in the frequency converter, and reducing fault rate.

Description

technical field [0001] The invention relates to a radiator, in particular to a frequency converter with automatic temperature control and heat dissipation. Background technique [0002] With the rapid development of modern electric power technology and computer control technology, the technical revolution of electric drive has been promoted. The frequency converter is one of the important electrical appliances widely used in the industrial field. The frequency converter is composed of a rectifier circuit, an intermediate circuit, an inverter and a control circuit. The frequency converter is a key component of the energy-saving control link and generates a large amount of heat. Therefore, the control cabinet of the frequency converter is equipped with ventilation and cooling channels and ventilation and cooling holes. [0003] However, long-term operation will lead to a great increase in heat. If the inverter is not cooled in time, it will easily lead to damage to electronic...
