An object of the present invention is to provide a vehicular air conditioning apparatus capable of varying the temperature of air that has passed through a heater core in the up-down direction of the heater core while achieving downsizing. The vehicular air conditioning apparatus includes an electric heater (43) that is provided in a flow channel defined by a housing on the downstream side of an evaporator, that includes heater circuits (48, 49), and that configures a heater core (17) that heats air cooled by the evaporator, and a control device (25) that separately controls the heater circuits (48, 49). The heater circuits (48, 49) are arranged in the up-down direction of the heater core (17).

An electrical heating apparatus for a motor vehicle includes a volume for receiving and conducting a liquid, a liquid inlet and a liquid outlet. The liquid can flow in through the liquid inlet into the volume and can flow out through the liquid outlet. At least one heating element is arranged in the volume. At least one deviating device is provided in such a way that the liquid flowing from the liquid inlet to the liquid outlet is deviated so that a flow path is increased.

Heat flow management device for motor vehicles has a refrigerant circulation, a power train coolant circulation and a heating line heat carrier circulation. The refrigerant circulation includes a compressor, an indirect condenser, an expansion element, an ambient heat exchanger, an evaporator and a chiller. The power train coolant circulation includes a coolant pump, the chiller, an electric motor heat exchanger and a power train coolant radiator, wherein the heating line heat carrier circulation comprises a coolant pump, the indirect condenser and a heating heat exchanger, wherein the refrigerant circulation and the power train coolant circulation are directly thermally coupled with one another across the chiller. Refrigerant circulation and heating line heat carrier circulation are directly thermally coupled with one another across the indirect condenser. Power train coolant circulation and the heating line heat carrier circulation are only indirectly thermally coupled with one another across the refrigerant circulation.

There is disclosed a vehicle air conditioner which is capable of achieving protection of an air flow passage without hindrance, even when a temperature sensor which detects a temperature of an electric heater fails. When a detected value of an electric heater temperature sensor detecting the highest temperature among a plurality of electric heater temperature sensors 61 to 64 is in excess of a predetermined threshold value, a controller executes a protecting operation of limiting energization to the electric heater or stopping the energization. The controller calculates an estimated value Thtrest of the temperature which is calculated back from a consumed power of the electric heater, and when one of the electric heater temperature sensors fails, the controller executes the protecting operation on the basis of the highest value among the detected values of the temperature sensors other than the electric heater temperature sensor and the estimated value.

Thus, a connection hose for connection components is removed or a length thereof is minimized, a fluid pump and a valve housing are reduced, thereby reducing costs.

A vehicular heat management system includes a refrigerant circulation line configured to cool or heat a passenger compartment by generating a hot air or a cold air depending on a flow direction of a refrigerant, a cooling water circulation line configured to heat the passenger compartment with waste heat of an engine by allowing cooling water of the engine to circulate through a heater core, a refrigerant-cooling water heat exchanger disposed in the cooling water circulation line to allow the refrigerant and the cooling water to exchange heat, and an engine cooling water independent circulation unit configured to allow the cooling water passed through the engine to bypass the heater core and the refrigerant-cooling water heat exchanger.

An interior lining element, for example for a passenger compartment of a vehicle, including a single-layer or multilayer decorative covering, the front side of which faces the passenger compartment and delimits the latter physically and, via the back side thereof, is in thermally conductive contact with a printed heater, where the heater has a plurality of flat resistance elements and at least two feed lines which are electrically highly conductive as compared with the resistance elements and via which the resistance elements can be looped into an electric circuit, and where in contact-making regions of the resistance elements and of the feed lines, one feed line and one resistance element are each printed overlapping each other.

A control system for a radiant heater device includes a radiant heater device, a heater ECU that controls an energization and a deenergization of a heat generation unit, and an integrated ECU that transmits an operation prohibition command for prohibiting the energization of the heat generation unit and an operation permission command for permitting the energization of the heat generation unit to the heater ECU. The integrated ECU transmits the operation prohibition command when receiving a collision signal indicative of a vehicle collision or a prediction of the vehicle collision, and transmits the operation permission command when not receiving the collision signal. The heater ECU performs the deenergization control when a non-reception state in which the operation permission command is not received from the integrated ECU is continued for a predetermined time or more. As a result, the energization can be interrupted before an occupant is adversely affected.
