FAN CONTROL UNIT AND POWER CONDITIONER |
| 摘要 |
A fan control unit includes: an internal fan that is provided inside a casing, in which an inverter containing a switching element is disposed, and generates an air current for air-cooling inside the casing; a heat sink which is exposed inside a duct provided on the casing and to which the switching element is attached, the duct being provided with an air-intake port and an air-exhaust port; an air-intake fan disposed at the air-intake port of the duct; an air-exhaust fan disposed at the air-exhaust port of the duct; and a control section performing a control such that the air-exhaust fan is turned on earlier than the air-intake fan and the internal fan as output power increases, and that the internal fan and the air-intake fan are turned off earlier than the air-exhaust fan as output power decreases from a state in which all the fans are kept turned on. |

1. A fan control unit comprising:
an internal fan that is provided inside a casing, in which an inverter containing a switching element is disposed, and generates an air current for air-cooling inside the casing; a heat sink which is exposed inside a duct and to which the switching element is attached, the duct being provided on an outer periphery of the casing, the duct being provided with an air-intake port and an air-exhaust port; an air-intake fan disposed at the air-intake port of the duct; an air-exhaust fan disposed at the air-exhaust port of the duct; and a control section for controlling the internal fan, the air-intake fan and the air-exhaust fan depending on output power of the inverter, wherein the control section causes the air-exhaust fan to be turned on earlier than causing the air-intake fan and the internal fan to be turned on as the output power increases, and causes the internal fan and the air-intake fan to be turned off earlier than causing the air-exhaust fan to be turned off as the output power decreases from a state in which all of the internal fan, the air-intake fan and the air-exhaust fan are kept turned on. |
