  • Patent number: 10982627
    Abstract: A system and method of controlling variable speed coolant pumps for vehicle cooling systems utilizes a controller that incorporates measured heat rejection and hydraulic system performance data of the cooling system. The controller calculates coolant flow and pressures at reduced coolant pump speeds. The controller then predicts coolant temperatures at the reduced water pump speeds, and establishes a maximum allowable heat flux to avoid boiling of the coolant. The controller then optimizes the speed of the variable speed coolant pump to prevent the coolant from exceeding the maximum allowable heat flux. The maximum allowable heat flux may be determined by keeping the heat flux within a region characterized by interface evaporation pure convection and/or within a region characterized by nucleate boiling bubbles condensing. The controller may also determine power savings created by optimizing the speed of the coolant pump.
