A heating, ventilation, and air conditioning (HVAC) system for a vehicle. The HVAC system includes an HVAC case. The HVAC case has a first inlet and a second inlet. The first inlet is in receipt of airflow from a front blower. The second inlet is in receipt of airflow from a rear blower. A front foot outlet directs airflow towards the feet of occupants at a front of the vehicle. A rear foot outlet directs airflow from the rear blower towards a rear of the vehicle. A rear-to-front airflow control door is movable to direct airflow generated by the rear blower and heated by a heater core through the rear foot outlet, through the front foot outlet, or simultaneously through both the rear foot outlet and the front foot outlet.

An HVAC system includes an evaporator housing having an evaporator disposed therein, and a heater housing having a heater disposed therein. The heater housing is configured to be removably coupled to and supported by the evaporator housing.

An air conditioning module, which can perform cooling and heating through a single module, which is capable of being compact-sized, which can prevent problems caused by condensate water because the condensate water can be easily discharged out, and which can control all of two doors for heating and cooling by a link member and an actuator.

A thermal management system for an electric vehicle having a drivetrain flow path coupling one or more motors and one or more inverters to an aerodynamic heat exchanger comprising one or more body panels disposed along an outer surface of the vehicle, the aerodynamic heat exchanger having one or more fluidic chambers or micro-channels. The drive flow path is decoupled from the vehicle's chiller and/or refrigeration cycle under all operating conditions. The drivetrain may be further characterized by the one or more motors being disposed proximate one or more wheels of the vehicle, such as within the wheel skirt or cowling, to capitalize on passive or free cooling via ambient airflow about the wheel. The thermal management system may further include a refrigeration cycle wherein the cabin and the battery pack are provided cooling in a parallel configuration or in a serial configuration.

A vehicle air conditioning apparatus includes an air conditioning case including a case body having a case opening that is open to an air conditioning opening, and a case cover that can open and close the case opening. The case cover can be attached/detached to/from the case body via the air conditioning opening outside of the vehicle interior. An evaporator and a heater can be attached/detached to/from the case body via the air conditioning opening outside of the vehicle interior, while the case cover is removed from the case body to open the case opening.

A method for servicing a heater core installed in a heating, ventilation, and air-conditioning (HVAC) assembly for a motor vehicle includes removing a sealing attachment from an interfacing connection interfacing with the heater core. The method includes sliding the heater core in a direction of insertion. The method includes disconnecting, from the heater core, the interfacing connection. The method includes removing the heater core in a direction of extraction, the direction of extraction being orthogonal to the direction of insertion.

A plate arrangement for fluid flow includes a support plate, and a plurality of channel plates detachably mounted on the support plate, wherein the plurality of channel plates are mounted to cover at least a portion of the support plate, each channel plate has a fluid channel, the plurality of channel plates are arranged along a fluid flow path of at least a portion of a predetermined fluid circulation loop so that the plurality of channel plates form at least the portion of the fluid circulation loop, and fluid channels of adjacent channel plates are fluidly connected to each other.

Cooling module including a housing configured to accept a tangential-flow turbomachine having a turbine with at least one stage of blades forming a hollow cylinder, the turbomachine also having a motor configured to drive the rotation of the turbine, the motor including a stator and a rotor mounted with the ability to rotate about the stator. The stator of the motor is secured to the housing in such a way that the blades of the turbine are arranged circumferentially around the rotor of the motor, and in that the at least one stage of blades of the turbine is mechanically connected to the rotor of the motor so as to be driven in rotation thereby.

An air-handling system for a vehicle includes a housing defining a first flow path through which a first flow of air is configured to selectively flow and a second flow path through which a second flow of air is configured to selectively flow. A heat exchange passageway provides fluid communication between the first flow path and the second flow path within the housing. A heat sink is disposed within the heat exchange passageway and is associated with cooling a linear power module of a blower assembly disposed within the housing. The heat sink is configured to exchange heat with air disposed within the heat exchange passageway to provide cooling of the linear power module regardless of a mode of operation of the blower assembly.

An electric vehicle air conditioning system includes: an outside air introduction portion that communicates an inside of a case configuring an outer shell of an air conditioning device with an outside of a vehicle; an air circulating portion that is disposed at the inside of the case, and that circulates air from an air circulating port provided at the case to an interior of a vehicle cabin, by being driven; and an air flow direction changing portion that is provided at the case, and that is moveable to direct a portion of air circulated from the air circulating portion to a heat generating device that is disposed at an inside of a power unit room.
