CONTROL OF RADIATOR COOLING FANS
First Claim
1. A method, comprising:
- determining heat input to a cooling system from a heat source;
determining a ram air flow velocity through a radiator of the cooling system;
selecting one or more fans of a plurality of radiator cooling fans to remove at least a portion of the heat input, the selection of the one or more fans based at least in part upon the heat input from the heat source and the ram air flow velocity; and
adjusting operation of the plurality of radiator cooling fans in response to the selection of the one or more fans.

Abstract
Various methods and systems are provided for the control of radiator cooling fans. In one example, among others, a method includes determining heat input to a cooling system and a ram air flow velocity through a radiator of the cooling system, selecting one or more radiator cooling fans, and adjusting operation of the fans in response to the selection. The selection of the fans can be based at least in part upon the heat input from the heat source and the ram air flow velocity. In another example, a system includes a plurality of cooling fans distributed across a cooling surface of a radiator of a cooling system and a radiator fan control system. The radiator fan control system can determine the heat input to the cooling system and a ram air flow velocity through the radiator, select one or more fans, and adjust operation of the selected fans.
