Adaptive cooling
The systems apply adaptive cooling based on customer environments to save energy.
Engines and DAEs access thermal data through components located within their
enclosures. Based on ambient temperature and internal activity, they set the cooling
fan speeds. As the inlet temperatures increase, the adaptive cooling increases the fan
speeds, with the resulting platform power increasing up to the maximum values shown
below. These values, along with the SPS recharge power consumption, contribute to
the maximum system power consumption values over 35°C shown in
25.
