A fan controller causes a fan assembly to flow air through a computer system at a variable airflow rate to cool the computer system. The ambient air temperature to the computer system is detected, and the controller varies the airflow rate as a function of the ambient temperature within an ambient temperature range having an upper limit. The upper limit on the defined ambient temperature range that is used by a fan speed control algorithm may be selectively reduced from a default value in response to electronic input, such from a user or a software object. Correspondingly, the controller limits the air flow rate to a reduced value corresponding to the reduced upper limit. The reduction in stranded power that results from reducing the upper limit on the ambient temperature may be re-allocated, such as to other racks in the data center.

An RF shield is fabricated from a solid piece of metal or metal alloy. Holes are cut through the metal or metal alloy at fixed positions to form an array. The diameter of the holes is selected to be significantly smaller than the RF wavelength (e.g., ⅓) it is designed to prevent from passing through the holes. The thickness of the plate (length of the holes) establishes the attenuation of the shield. The number of holes establishes the air or other fluid throughput.

In a power supply unit disposed below a floor behind a seat, battery modules are disposed in a lower position, and a DC / DC converter and a motor driving inverter are disposed side by side in a vehicle width direction above the battery modules. Thus, cooling air flowing from the front side to the rear side of a vehicle body is divided into upper and lower portions to cool in parallel the DC / DC converter 41 and the motor driving inverter on the upper side and the battery modules on the lower side. Thus, it is possible to simplify a passage of the cooling air to reduce the size of the entire power supply unit, and improve mountability of the power supply unit on the vehicle body. Also, it is possible to apply cooling air at low temperature before heat exchange to all the battery module, the DC / DC converter, and the motor driving inverter, thereby enhancing cooling effect.
