Abstract
A method for controlling a cooling system based on a heat dissipation of an electronic module and an ambient air temperature includes determining a combination of individual controls on components of the cooling system that achieve a specific amount of cooling based on a cooling power relationship for the plurality of components, the heat dissipation of the electronic module and the ambient air temperature, and applying the individual controls to the plurality of components.
Claims27
A method for controlling a cooling system based on a heat dissipation of an electronic module and an ambient air temperature, said method comprising:
- determining a combination of individual controls on a plurality of components of said cooling system that achieve a specific amount of cooling based on a cooling power relationship for said plurality of components, said heat dissipation of said electronic module and said ambient air temperature;
- and
- applying said individual controls to said plurality of components.
A method for controlling a cooling system comprising:
- determining a relationship between a delta temperature and a power usage for each of a plurality of cooling components of said cooling system;
- determining a low power setting from a combination of said relationships for said plurality of cooling components to maintain a temperature of interest at or below a target temperature;
- and
- generating a control signal to said plurality of cooling components according to said low power setting.
A computer program product for controlling a cooling system, the computer program product comprising:
- a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising:
- computer readable program code configured to determine a relationship between a delta temperature and a power usage for each of a plurality of cooling components of said cooling system;
- computer readable program code configured to determine a low power setting from a combination of said relationships for said plurality of cooling components to maintain a temperature of interest at or below a target temperature;
- and
- computer readable program code configured to generate a control signal to said plurality of cooling components according to said low power setting.
A control system cooling at least one electronic module, said control system comprising:
- a pump for pumping a coolant;
- a fan disposed at a heat rejection unit;
- and
- a controller controlling said pump and said fan individually based on a cooling power relationship, a heat dissipation of said electronic module and an ambient air temperature, wherein said cooling power relationship is a combination of a first relationship between a delta temperature and a power usage determined for said pump and a second relationship between a delta temperature and a power usage determined for said fan.
