Systems and methods for warming a battery and operator cab of an electric vehicle. A second thermal fluid is circulated in a second fluid circuit of a primary system, and is heated by an electric heater before being circulated to a first heat exchanger to heat a first thermal fluid in a fluid thermal tank. The heated first thermal fluid is circulated via a first fluid circuit of the primary system and to the battery, or selectively bypasses the battery and returns to the fluid thermal tank. Occasionally, an external system is coupled to a portion of a third fluid circuit residing in the primary system such that heated third thermal fluid from the external system flows to the first heat exchanger. Partially heated second or third thermal fluid can flow to a second heat exchanger such that the remaining heat entrained therein can heat the operator cab.

Systems and methods for managing the heating of thermal fluids

A two-phase cooling system of an electric work vehicle includes a compressor, a condenser, a thermal expansion valve, a heat exchanger, and an evaporator. The compressor compresses a refrigerant to increase the refrigerant pressure. The condenser is downstream of the compressor and discharges heat from the refrigerant flowing from the compressor to condense at least a portion of the refrigerant. The thermal expansion valve is downstream of the condenser and decreases the pressure of the refrigerant to vaporize the refrigerant to decrease the temperature of the refrigerant. The heat exchanger is coupled to an electrical component and is used to transfer heat from the electrical component to the refrigerant from the electrical component. The refrigerant then flows through the evaporator, where it absorbs more heat. The refrigerant passes back through the thermal expansion valve on its return to the compressor.

Two-phase cooling system

A method of removing debris from a screen cover has a first mode of operation which includes: activating first and second fans to move first and second portions of air through screen cover and into a plenum, and moving the first and second portions of air from the plenum into a heat exchanger. A second mode of operation includes: deactivating the first fan for a first time period, activating the second fan for the first time period to move a third portion of air into the plenum, moving a first part of the third portion of air from the plenum into the heat exchanger during the first time period, and moving a second part of the third portion of air from the plenum through the screen cover during the first time period such that the second part of the third portion of air removes debris from the screen cover.

Method of cleaning an air inlet screen of a work vehicle

A control system for controlling a work machine includes an engine for producing power to propel the work machine during a normal operating mode, a cooling system for cooling at least the engine during the normal operating mode, and a controller for controlling the cleaning system during the normal operating mode and a clean operating mode. During the normal operating mode, the engine is running and the controller operably controls a cooling fan of the cooling system to rotate in a first rotational direction to produce a first air flow in a first direction. During the clean operating mode, the engine is not running and the controller operably controls the cooling fan to rotate in a second rotational direction to produce a second air flow in a second direction. The first rotational direction is opposite the second rotational direction, and the first direction is opposite the second direction.

Method for cleaning cooling system of a work machine and system thereof

A work vehicle includes an engine, a compressor used to compress an air toward the engine, a charge air cooler, a sensor, and a control unit. The charge air cooler comprising or coupled to a fan. The fan can rotate in a first direction to remove a heat of the air and to rotate in a second direction reverse to the first direction so as to blow a debris. The control unit is electrically coupled to the engine and to the fan. The control unit predicts whether a temperature of the air exceeds a threshold based on a signal received from the sensor. When the temperature of the air is below the threshold, the fan can rotate in the second direction. When the temperature of the air is equal to or above the threshold, the fan is inhibited from rotating in the second direction.

Charge air cooler fan control

A multiplane fan cooling system and method is disclosed for a cooling system with first, second and intake planes; a first fan and heat exchanger on the first plane, a second fan and heat exchanger on the second plane, and a shared air cavity bounded at least partially by these three planes. Each fan pulls air into the shared air cavity through the intake plane and across its associated heat exchanger. The first fan cools the first heat exchanger, and counteracts the second fan from drawing air into the shared air cavity through the first heat exchanger. The second fan cools the second heat exchanger. The second fan can be activated to counteract the first fan from drawing air into the shared air cavity through the second heat exchanger. All the air in the shared air cavity can be available to each of the fans.

A heat exchanger system for use with heavy equipment including a heat exchanger rotatable about a horizontal axis out of a frame.

Stacked heat exchanger system with swing-out heat exchangers

A controlled engine shutdown method is disclosed that includes monitoring exhaust system temperature, monitoring operator shutdown commands, and delaying engine shutdown based on exhaust system temperature. The method can include inhibiting any process that affects exhaust temperatures, for example DPF regeneration. The method can use a shutdown timer, allow operator override of the shutdown delay, and display a delay notification message. The method can also include predicting when an engine shutdown is expected, and delaying or aborting any process that would affect exhaust temperatures when an engine shutdown is predicted. Predicting can include monitoring various machine states, determining an average activity interval for the machine, determining a geographic shutdown area, determining a shutdown time of day and/or monitoring a machine fluid level.

A vehicle includes a chassis; a plurality of ground-engaging members; and an engine that cooperates with the plurality of ground-engaging members to move the chassis of the vehicle. The engine is positioned within an engine compartment. The vehicle further includes a cooling system including a baffle having a first side and a second side; a battery positioned on the first side of the baffle; and a heat exchanger positioned on the second side of the baffle. The baffle defines a first air pathway to cool the battery and a second air pathway to cool the heat exchanger.

Use of fan shroud to ventilate engine compartment

A work machine comprises a baffle configured to divert air flow from a source of pressurized air laterally outwardly toward a peripheral edge of the baffle to create a flow-inducing region about the peripheral edge to ventilate the engine compartment.
