A thermal management system of a vehicle includes: a cooling circuit in which cooling water circulates; a heat accumulator storing the cooling water; a flow control valve adjusting a flow rate of the cooling water flowing to the heat accumulator; a radiator; a thermostatic valve adjusting the flow rate of the cooling water flowing to the radiator; a grille shutter adjusting amount of outside air introduced from a front grille into an engine room; a cooling water temperature sensor; a heat radiation control unit supplying the cooling water to the cooling circuit to warm up an engine when the engine is cold; and a heat storage control unit, by controlling opening degrees of the flow control valve and the grille shutter according to a cooling water temperature, supplying from the cooling circuit to the heat accumulator the cooling water whose temperature is raised by heat of the engine.

A surgical stapler including an anvil, a staple cartridge, and a buttress material removably retained to the anvil and/or staple cartridge. In various embodiments, the staple cartridge can include at least one staple removably stored therein which can, when deployed, or fired, therefrom, contact the buttress material and remove the buttress material from the anvil and/or staple cartridge. In at least one embodiment, the anvil can include at least one lip and/or groove configured to removably retain the buttress material to the anvil until deformable members extending from the surgical staple are bent by the anvil and are directed toward and contact the buttress material.

Provided is an engine cooling apparatus capable of preventing deterioration in reliability of a cylinder head of an engine during cold engine operation. The engine cooling apparatus comprises an engine cooling water path, a heater core cooling path, and a radiator cooling water path, and further comprises a switching valve for switching among these cooling water paths. The switching valve is operable, when the temperature of an area around an exhaust valve is raised to a value greater than, e.g., 150 C., even in a situation where the temperature of cooling water for cooling the engine is equal to or less than, e.g., 50 C., to switch from the in-engine cooling water path to the heater core cooling water path.

A method and apparatus for active coolant volume reduction management in a pressurized reservoir coolant diverter for automobile applications. Specifically, an apparatus and method for diverting coolant flow around a pressurized coolant reservoir until the engine has reached operating temperature by employing a coolant bypass chamber and bypass shutoff valve and the like.

A method for controlling a water pump for a vehicle includes: determining whether an engine is on; measuring a coolant temperature of the engine and an RPM of the engine when the engine is determined to be operated; determining whether the measured coolant temperature is equal to or greater than a predetermined coolant temperature; determining an RPM of a water pump, which adjusts a coolant flow rate, from the measured coolant temperature and the measured RPM of the engine, when the measured coolant temperature is determined to be equal to or greater than the predetermined coolant temperature; and controlling the water pump such that the water pump is operated according to the determined RPM of the water pump.

A vehicle thermal management system including an engine, a vehicle cabin, a transmission thermal loop, and a controller is provided. The transmission thermal loop may include a transmission assembly in operational communication with the engine and a cabin thermal loop. The controller may be programmed to, responsive to detection of an engine off condition, output to a shut-off valve an open command such that heat from the transmission thermal loop transfers to the cabin thermal loop to warm the vehicle cabin. The controller may be further programmed to, responsive to detection of a cabin heater core having a temperature above a predetermined threshold, output a command to a coolant heater of an engine thermal loop to direct warm or cold fluid to the transmission assembly based on a detected transmission thermal loop temperature.

An engine coolant temperature at an expected time of activation of a vehicle is predicted. Upon determining that the predicted engine coolant temperature is greater than an ambient air temperature by a temperature threshold, a vehicle component is actuated at a time determined based on the expected time of activation.

A coolant pump for a vehicle may include an impeller mounted at one side of a shaft and pumping a coolant, a pulley mounted at the other side of the shaft and receiving a torque, a pump housing of which an outlet for the coolant to flow out therethrough is formed thereto, an inflow portion including a first inlet and a second inlet configured for receiving coolant, a slider of which a first closing portion selectively closing or opening the outlet and a second closing portion selectively closing or opening the second inlet are formed thereto, and the slider disposed slidable along longitudinal direction of the shaft and a driver moving the slider.

The control apparatus includes a heater configured to generate heat to heat the internal combustion engine, a controller configured to control a heat exchange system in such a way as to transfer EV exhaust heat to the internal combustion engine, and an controller configured to let electrical power be supplied from a battery to the heater before the internal combustion engine is started if it is predicted that a specific warmed-up condition of the internal combustion engine will not be established before the start of the internal combustion engine and not to let electrical power be supplied from a battery to the heating if it is predicted that a specific warmed-up condition of the internal combustion engine will be established before the start of the internal combustion engine.

Methods and system are provided for a cooling arrangement of an engine. In one example, the cooling arrangement may include first and second cooling ducts, where the second cooling ducts are arranged in gaps formed between adjacent cylinders and the first ducts are arranged outside of the gaps of the adjacent cylinders.
