A cooling system includes an internal combustion engine, a coolant pump in fluid communication with the internal combustion engine, and a liquid-to-liquid heat exchanger configured to receive coolant from the internal combustion engine via the coolant pump. The cooling system also includes a bypass valve connected downstream of the coolant pump, the bypass valve configured to close a fluid path that connects the coolant pump and the liquid-to-liquid heat exchanger.

Models that employ both measurable engine parameters as well as predictable engine parameters may be used to determine when a thermostat is malfunctioning before the thermostat malfunction results in an engine breakdown. Particular models may be used to provide an estimated coolant temperature and an estimated thermostat position. The estimated coolant temperature can be compared to an actual measured engine coolant temperature. The estimated thermostat position can be evaluated with respect to what the thermostat position should be given a particular engine coolant temperature. In some cases, comparison between a healthy model and a faulty model may be used to ascertain thermostat health.

The warm-up method based on the temperature control module comprises: entering a cold start mode; obtaining current temperature control parameters, the temperature control parameters comprising a current water temperature value, a current engine speed, and a current engine load; obtaining working parameters of a temperature control module according to the temperature control parameters; controlling the temperature control module according to the working parameters to adjust the water temperature to warm an engine, and updating the current water temperature value; and after the updated current water temperature value does not exceed a warm-up threshold, returning to the step of obtaining the current temperature control parameters to enter the next cycle.

An Integrated thermal management valve (ITM) control apparatus of a vehicle includes a driving information generator that generates driving information of the vehicle, a refrigerant pressure measuring device that measures a refrigerant pressure of a vehicle air conditioner of the vehicle, and an ITM controller that is configured to control the ITM of the vehicle, according to the generated driving information and the measured refrigerant pressure.

A thermostatic valve includes a hollow body, two openings opening into the body and being hydraulically connected by a pass section, and a shut-off component arranged partially in the pass section and having a thermostatic actuator, a return component, a valve capable of opening the first opening when actuated by the thermostatic actuator and of closing the first opening when returned by the return component. The thermostatic actuator includes a cylinder containing an expansion material and a stem defining an axial direction. A relative movement between the cylinder and the stem along the axial direction occurs under the action of the expansion material. The stem bears at an ends against an abutment element, which is movable under the action of movement component in the direction of the cylinder to allow the opening of the first opening when the temperature of the expansion material is below the threshold temperature.

A device that includes a thermostatic element, with a piston and a body movable along an axis with respect to one another under the effect of the expansion of a thermodilatable material, and a stopper moved axially by the body with respect to a fixed seat so as to open and close a fluid circulation passage. The stopper includes a flexible seal which rests sealingly against the fixed seat in order to close the passage, and a rigid frame which fixedly supports the seal. The frame includes a central portion, mounted around the body to be driven by the body, and a peripheral part, folded towards the axis, partially crushing the seal. The seal is held in place on the frame by being pushed, radially to the axis, directly against the body of the thermostatic element under the effect of crushing the seal by the peripheral portion of the frame.

An exemplary thermal management system includes, among other things, a valve, a radiator loop configured to be connected to the valve, a power electronics loop configured to be connected to the valve, a heater loop configured to be connected to the valve, and a battery loop configured to be connected to the valve. The valve is configured to connect one or more of the radiator, power electronics, heater, and battery loops together and the valve is configured to isolate at least one of the radiator, power electronics, heater, and battery loops from any remaining loops of the radiator, power electronics, heater, and battery loops.

An engine system is provided, including an engine having a water jacket, a circulation system that circulates coolant through the water jacket, and a controller. The circulation system includes a radiator passage including a heat exchanger, a bypass passage bypassing the heat exchanger, a flow rate control device, and a thermally-actuated valve connected to the radiator passage and that opens to allow the coolant to pass through the heat exchanger. When an engine load is below a first load, the controller controls the flow rate control device to adjust the coolant flow rate flowing through the water jacket according to the load, by closing the radiator passage and adjusting the coolant flow rate flowing through the bypass passage. When the load is above the first load, the controller controls the flow rate control device so that the coolant flows through each of the radiator passage and the bypass passage.

The invention concerns a thermostatic valve (1) comprising a closed hollow body (2), a first opening leading into the hollow body (2), referred to as the inlet opening (4), a second opening leading into the hollow body (2), referred to as the main outlet (5), a third opening, substantially perpendicular to the second opening, leading into the hollow body (2), referred to as the bypass outlet (7), and a seal (11) allowing the inlet opening (4) to be alternately separated from the main outlet (5) or the bypass outlet (7). The seal (11) comprises a thermostatic actuator (12) and a skirt (13) which is made of plastic material and has at least one window (19) suitable for being traversed by a fluid, the skirt (13) being capable of sliding in the hollow body (2), along an axis that substantially coincides with the axis of the thermostatic actuator (12), between a first position in which the skirt (13) seals the main outlet (5), such that the fluid flows between the inlet opening (4) and the bypass outlet (7), and a second position in which the skirt (13) leaves the main outlet (5) open and seals the bypass outlet (7), such that the fluid from the inlet opening (4) can pass through the window (19) and flow through the main outlet (5).

A controller includes at least one processor coupled to a memory storing instructions that, when executed by the at least one processor, cause the at least one processor to: determine a target engine outlet coolant temperature for a coolant in an engine system; determine an adjustment to a temperature of the coolant based on a determined engine inlet coolant temperature and the target engine outlet coolant temperature; and, alter a flow of the coolant by controlling a coolant valve in response to the determination of the adjustment to the temperature of the coolant.
