摘要:
A highly reliable electronic apparatus free from condensation in the cabinet of the apparatus. The electronic apparatus has printed circuit boards on which heat emitting semiconductor devices are mounted and a fan. The electronic apparatus further comprises a hygrometer for measuring the relative humidity and dew-point temperature of the cooling air that is introduced into the cabinet through an opening, a surface temperature sensor for sensing the temperature of the surface of the semiconductor devices, an internal temperature sensor for sensing the internal temperature of the semiconductor device, dehumidifier and heater means made up of a heat pump and an outdoor unit, and a controller for controlling the dehumidifier means and the heater means so that the relative humidity is less than 100% and the dew-point temperature is less than the surface temperature of the semiconductor devices.
