A temperature control apparatus of a vehicle of the invention flows a cooling medium in an engine circulation circuit and a battery circulation circuit and an activation of an engine heat exchanging system so as not to perform an engine heat exchanging when an engine temperature is lower than an engine warming end temperature and a battery temperature is lower than a predetermined battery temperature lower than a battery warming end temperature, and flows the cooling medium in the engine circulation circuit and the battery circulation circuit and the activation of the engine heat exchanging system so as to perform the engine heat exchanging when the engine temperature is lower than the engine warming end temperature, and the battery temperature is equal to or higher than the predetermined battery temperature.

A coolant reservoir tank includes a first compartment that is configured to receive and retain a first portion of a liquid coolant. The first compartment is configured to be in fluid communication with a first liquid cooling circuit. A second compartment is configured to receive and retain a second portion of the liquid coolant. The second compartment is configured to be in fluid communication with a second liquid cooling circuit. A dividing wall separates the first compartment from the second compartment. The coolant reservoir tank further includes a fill port.

A cooling circuit for a vehicle includes: an electronic device disposed on a sub-water-cooling line; an intercooler disposed in parallel with the electronic device on the sub-water-cooling line; and a sub-radiator disposed on the sub-water-cooling line and configured to cool cooling water which passes through the electronic device and the intercooler before passing through the sub-radiator.

Disclosed are two-valve, split-layout engine cooling systems, methods for making and method for operating such cooling systems, engine coolant valve assembly configurations, and vehicles equipped with an active thermal management system for cooling select powertrain components. A disclosed thermal management system includes a radiator for cooling coolant fluid, and a coolant pump for circulating coolant fluid received from the radiator. A set of conduits fluidly connect the coolant pump to an engine block, a cylinder head, and an exhaust manifold. Another set of conduits fluidly connect the engine block, cylinder head, and exhaust manifold to the radiator, coolant pump, and one or more oil heaters. A first valve assembly is operable to regulate coolant flow between the coolant pump and the radiator. A second valve assembly is operable to regulate coolant fluid flow, individually and jointly, between the engine block, cylinder head, exhaust manifold, radiator, coolant pump, and oil heater(s).

A liquid cooling circuit includes a liquid reservoir for coolant, a heat-generating module, a conduit fluidly coupling the heat-generating module with the liquid reservoir, and a pump configured to move the coolant through the conduit to cool the heat-generating module. The liquid cooling circuit is configured such that the movement of the coolant relative to the heat-generating module transfers heat from the heat-generating module to the coolant.

An under-hood mounting configuration for a work vehicle may generally include an air intake component positioned upstream of an engine of the work vehicle. The air intake component may include a wall having an exterior surface and an interior surface. The wall may define a cooling port extending between the exterior surface and the interior surface. In addition, the under-hood mounting configuration may include a control unit having a housing defining an upper surface and a lower surface opposite the upper surface. The housing may be mounted to the wall along the exterior surface such that the housing is positioned directly over at least a portion of the cooling port. When the airflow is directed through the air intake component, a portion of the airflow may flow through the cooling port and may be directed towards the lower surface of the housing.

The present invention relates to an integrated cooling system for a vehicle. The system includes an engine cooling loop having a first fluid configured for circulation through an engine of the vehicle and a power electronics cooling loop having a second fluid configured for circulation through at least one power electronics component of the vehicle. The engine cooling loop is fluidly isolated from, and in thermal communication with, the power electronics cooling loop.
