Although the inverter is installed independently outside the HVLS Fans, as the control system of the ceiling fan, it can be said to control the start and stop actions of the entire ceiling fan, and its role cannot be ignored. Especially in hot weather, rainy days, and crowded places, Hvls Ceiling Fans will be used frequently and for a lot of time. Then the more times the inverter is used, the inverter may overheat, causing the HVLS Fans to fail and no longer be used. Regarding the heat dissipation and overheating of the frequency converter, how should we deal with it.
According to most research phenomena, a large part of the failure of the frequency converter is due to the increase in temperature, and its service life decreases with the increase in temperature. The causes of Hvls
Ceiling Fans failure due to overheating of the inverter are as follows:
1. The inverter is composed of countless electronic devices, which will generate a lot of heat when working. Especially when the IGBT works at high frequency, it will generate more heat. If the ambient temperature is too high, the temperature of the internal components of the frequency converter will also be too high. In order to protect the internal circuit of the frequency converter, the frequency converter will report a high temperature fault and stop the machine.
2. When the air duct of the frequency converter itself is blocked or the air duct of the control cabinet is blocked, it will affect the internal heat dissipation of the frequency converter, causing the frequency converter to overheat and alarm.
3. The Hvls Ceiling Fans of the inverter is broken, and a large amount of heat accumulates in the inverter and cannot be dissipated.
4. When the load carried by the frequency converter is too heavy, excessive current and a large amount of heat will be generated, and the frequency converter will overheat and alarm.
Understanding the overheating problem of HVLS Fans can directly prescribe the right medicine. "Solving the heat dissipation of the frequency converter is the key. The operating temperature of the frequency converter usually needs to be in the range of -10℃-+40℃, preferably around 25. Whether the frequency converter is overheated, you can Use an infrared thermometer to check whether the heat sink is overheated or smells strange, and check whether the inverter has an alarm display indicating a running failure.
The inverter has certain requirements for the surrounding temperature. Ventilation and heat dissipation of the installation site of the inverter should be strengthened to ensure that the surrounding air does not contain excessive dust, acid, salt, corrosive and explosive gases. All frequency converters should be installed vertically and at a certain distance from surrounding barriers.
In order to prevent foreign objects from falling on the air outlet of the frequency converter and blocking the air duct, it is necessary to install a protective mesh cover above the air outlet of the frequency converter, and clean the Hvls Ceiling Fans and air duct regularly to prevent clogging. The Hvls Ceiling Fans installed in the control box is inside the frequency converter. It is the main means of heat dissipation. It will ensure the normal operation of the control circuit. If the Hvls Ceiling Fans operates abnormally or is damaged, it should be replaced immediately, reduce the load or increase the capacity of the inverter. Regularly check the operating status of the inverter and whether the voltage and current values are within the normal range. within, and reduce the load of the inverter or increase the capacity of the inverter.
