A governing system of an engine coolant control system in which first and second portions of coolant are pumped from an engine to a regulator and back to the engine and from the engine to a radiator and back to the engine, respectively, is provided. The governing system includes a temperature sensor of the engine to sense coolant temperatures, an ambient temperature sensor of the radiator to sense ambient temperatures, a heating element disposed to heat the first portion of the coolant at one of a location upstream from the regulator and the regulator, a valve operably disposed along a section of piping through which the first portion of the coolant flows from the engine to the regulator and a controller which controls operations of the heating element and the valve in accordance with the readings of the temperature sensor of the engine and the ambient temperature sensor.

An agricultural system including an agricultural baler and a control unit. The baler includes a driveline including at least one heat generating component; a rotatable flywheel; a rotary input shaft connectable by the driveline to the rotatable flywheel; and at least one pump for supplying cooling fluid at a cooling fluid pressure to the at least one heat generating component. The control unit is configured to: receive baler-data indicative of one or more operating conditions of the agricultural baler; receive cooling-pressure-data indicative of a flow of the cooling fluid supplied by the at least one pump; set a threshold-condition based on the baler-data; and provide a control-signal to the agricultural baler based on a comparison between the cooling-pressure-data and the threshold-condition.

A vehicle heat transfer system includes a flow through heat exchanger, a surface heat exchanger, at least a first vehicle component, and a controller that is operable to selectively transfer heat to or from the first vehicle component with either or both of the flow through heat exchanger and the surface heat exchanger based on one or more operating conditions. In a further aspect, a vehicle heat transfer system includes, a vehicle component positioned on a vehicle that is heated or cooled by a fluid, and a surface heat exchanger positioned on the vehicle, the surface heat exchanger having an inlet that receives the fluid used to heat or cool the vehicle component, an outlet that returns the fluid to heat or cool the vehicle component, and a closed fluid path extending between the inlet and the outlet.

The invention relates to a heat exchanger comprising a first free space (7) for a first fluid (3), a thermally conductive wall (11) which, at least locally, delimits said first free space (7), in such a way that an exchange of heat can occur between the first fluid and the thermally conductive wall (11) which is hollow and encloses a material (13) for storing thermal energy by accumulation of latent heat, by heat exchange with at least the first fluid. The first free space (7) is divided into at least two separated channels (7a, 7b) in which two streams of the first fluid (3) can circulate at the same time but separately, the thermally conductive wall (11) which encloses the thermal energy storage material (13) being interposed between the two channels (7a, 7b).

A clutch device for a vehicle fan includes a drive-side clutch element and an output-side clutch element. The clutch device includes a locking mechanism configured between the drive-side clutch element and the output-side clutch element so that a rotary connection established between the drive-side clutch element and the output-side clutch element is released when a drive-side rotational speed reduces in comparison with an output-side rotational speed.

A system for controlling a fan in a vehicle having a heat exchanger may include defining first and second geographic areas and determining a geographic location of the vehicle. A processor may be programmed to send a signal to operate the fan in a first rotational direction to move air through the heat exchanger in a first direction, and to send a signal to the fan to operate it in a second rotational direction opposite the first rotational direction to move air through the heat exchanger in a second direction opposite the first direction when a plurality of conditions are met.
