Abstract

The invention discloses a frequency converter heat dissipation structure and a heating furnace, wherein the frequency converter heat dissipation structure is used for frequency converter heat dissipation, and the heat dissipation structure includes a base for installing the frequency converter and a metal plate arranged on the base Cover; the metal cover and the base enclose to form an air duct, the frequency converter is arranged in the air duct, and a fan is provided at one end of the air duct. The present invention adopts the metal cover and the base to form an air duct, uses the fan to realize forced air cooling, and utilizes the air duct structure to realize the concentrated air flow to the frequency converter, which can improve the air cooling efficiency; due to the use of the metal cover structure, it can play a role in the frequency converter. The shielding effect prevents the frequency converter from interfering with other equipment, which helps to ensure the stability of the system. At the same time, it can also prevent other equipment from interfering with the frequency converter and ensure the normal operation of the frequency converter.

Description

Technical field [0001] The present invention relates to the field of kitchen appliances, and more particularly to a frequency converter heat dissipation structure and a heating furnace. Background technique [0002] The inverter is a product of the advancement of the inquiry technology in the field of electrical transmission in the 20th century. The failure rate of the inverter is rising index with the temperature, and the service life is decreased with the increase in temperature. The temperature increase is 10 degrees, and the use of the inverter Half of life. In order to achieve heat dissipation effect, the existing inverter is mounted directly on one airway, and the fan is used to flow in the air, forced air cooling. During the inverter operation, in the mounting method of the heat dissipation structure, the nonlinear equivalent load of the inverter of the inverter causes the inverter to interfere with the system, and destroy the stability of the system.
