Abstract: In an electric water pump for circulating cooling water of an engine mounted on a vehicle or similar, a time interval to switch energized phase of a pump motor is set to longer than a time interval during a normal flow rate control (during a flow rate control at a flow rate equal to or more than a flow rate where an electromotive force generated at a non-energized phase is detectable). In the case where a pump discharge pressure (or a water temperature of the cooling water) repeatedly increases and decreases in this extremely low flow rate state, it is determined that the electric water pump normally rotates as required. This allows providing the extremely low flow rate state between a water stop state and a water circulation state in a control for stop of water in an engine cooling system.

Abstract: A cooler apparatus includes: a coolant passageway; a water pump that circulates coolant in the coolant passageway; a thermostat that includes a heater that heats a temperature sensitive portion; and a controller. The controller is configured to drive the water pump and cause electric current to flow through the heater at a first energization amount when an operation in which the coolant is injected into the coolant passageway is started. The controller is also configured to stop electric current to flow through the heater if the water pump races when the electric current flows through the heater at the first energization amount.

Abstract: A cooling apparatus includes an electric water pump that circulates a coolant, a radiator that radiates heat of the coolant, an electric fan that cools the radiator, a control device, and first flow rate correction means. The control device controls the discharge flow rate of the electric water pump based on a target flow rate set based on an amount of heat generated in an engine, and controls operation of the electric fan based on a coolant temperature. When the coolant temperature is equal to or higher than a fan operation temperature at which the operation of the electric fan is started, the first flow rate correction means increases the discharge flow rate of the electric water pump in accordance with an increase in the coolant temperature.

Abstract: A cooling apparatus that cools with coolant a subject of cooling, which is a heat source. The cooling apparatus includes a cooling circuit, an electric pump, a switching section, and a control section. Through circulation of the coolant, air in the cooing circuit is caused to flow to an air bleeding portion and is discharged from the cooling circuit through the air bleeding portion. The switching section is capable of switching the operation mode of the electric pump between a normal mode and an air bleeding mode for collecting air in the cooling circuit to the air bleeding portion. During the air bleeding mode, the control section is capable of controlling the electric pump to change a coolant displacement from the electric pump according to a change pattern that allows stagnant air in sections of the cooling circuit to flow to the air bleeding portion.
