The present embodiments disclose a method of running an air inlet system upstream of one or more inlet air filters of a device protected by air filtration, wherein the method comprises: regulating the relative air humidity of the inlet air at the one or more inlet air filters in dependence of the inlet air filters differential pressure.

An engine fluid heating apparatus, preventing failure in heating fluid, is provided. A control device opens a sub switch during an initial opening period (IOP) after closing a main switch, and the control device closes the sub switch during an initial closing period (ICP) after the IOP. Circuit normality is displayed by turning on an indicator lamp when a heater feeding circuit is electrically conducted via a bypass electric circuit during the IOP. Heater feeding is displayed by turning off the indicator lamp when power is supplied to the electric heater via a trunk electric circuit during the ICP. Circuit abnormality is displayed by turning off the indicator lamp when the heater feeding circuit is not electrically conducted via the bypass electric circuit during the IOP, and the circuit abnormality display is held by keeping the indicator lamp off during the ICP immediately after the IOP.

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.

A coolant heating system includes: a coolant heater including: a housing including: an inlet configured to receive coolant; and an outlet configured to output coolant; an electrically resistive heating element that is disposed within the housing and that is configured to generate heat when power is applied to the heating element; and a temperature sensor configured to measure a temperature of coolant within the housing; and a heater control module configured to: receive the temperature from the temperature sensor; selectively control application of power to the heating element based on maintaining the temperature at or above a predetermined temperature; selectively detect the presence of a condition based on the temperature; and when the presence of the condition is detected, disconnect the heating element from power.

A modular integrated cooling system includes an enclosure, the enclosure including an outlet top opening and two or more inlet face openings. The modular integrated cooling system includes a fan positioned at the outlet top opening. The modular integrated cooling system includes two or more cooling cores positioned within the enclosure, each cooling core positioned at a corresponding inlet face opening.

The present embodiments disclose a system (100) for reducing inlet air temperature of a device, comprising: a fogging system that provides air cooling, wherein the fogging system comprises at least one low pressure atomiser (110).

A contact heater comprising a heating member and a contact surface, where the contact surface is adapted for abutment towards a portion of an engine, gearbox, or similar, which is to be heated. The heating member comprises at least one PTC element and connection means for electrical energy supply, and the contact surface constitutes a portion of a contact element which is releasably connected to the heating member by connection means. The contact heater is suitable for use on an engine, for example an automobile engine, an engine block, a sump, a gearbox or a part of the transmission system for a vehicle.

The invention relates to an electrical liquid heating device for a motor vehicle. The heating device comprises at least a first (7a) and a second (7b) heating module for heating the aforementioned liquid, defining at least one circuit (15) for guiding the liquid to be heated. The device is characterized in that the heating modules (7a, 7b) each have a generally cylindrical shape and are arranged side by side substantially in parallel. The invention also relates to a heating and/or air-conditioning unit for a motor vehicle, comprising such a heating device (5).

Methods and systems are provided for regulating coolant flow in a vehicle cooling system during an engine startup event. In one example, a method may include, during an engine startup event, controlling a flowpath of an engine coolant in a vehicle cooling system via a passive valve and an actively regulatable valve, and responsive to an engine coolant temperature below a threshold at the engine startup event, isolating the flowpath of engine coolant to a subsection of the cooling system to enable rapid warming of the engine coolant without stagnating the engine coolant at an engine. In this way, engine coolant may be rapidly warmed at an engine startup event, via coolant flow isolation, rather than coolant flow stagnation, which may decrease uneven heating of engine system components, and which may thus prolong a functional lifetime of the engine system.

A controller for a motor vehicle cooling system thermostatic valve assembly, the assembly having a radiator bypass coolant flow inlet, a radiator coolant flow inlet and a coolant outlet, the assembly being configured to allow flow of coolant from the bypass coolant flow inlet to the coolant outlet and from the radiator coolant flow inlet to the coolant outlet, the assembly comprising means for controlling a flow rate of fluid from the radiator coolant flow inlet to the coolant outlet, the controller being configured to receive an ambient temperature signal indicative of an ambient air temperature, the controller being configured to control flow of coolant from the radiator coolant flow inlet to the coolant outlet in dependence at least in part on the ambient temperature signal.
