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.

A vehicular air conditioner includes a casing, a blower fan, and a heating heat exchanger that is disposed in the casing. The heating heat exchanger is disposed downstream of the blower fan. The blower fan is disposed to extend over a first outside air space, a second outside air space, a first inside air space, and a second inside air space. The rotational direction of the blower fan is set so that each of the plurality of blades of the blower fan passes through the first inside air space, the first outside air space, the second outside air space, and the second inside air space in this order when the plurality of blade are rotating.

Disclosed is an air conditioner for a vehicle. The air conditioner includes a blower unit having an air blower which is erect, wherein the blower unit is arranged between an evaporator unit having an evaporator and a heater unit having a heater core in order to remarkably reduce the width of the air conditioner and maximize an internal space of the vehicle.

An air-conditioning unit for a vehicle has a case, a blower, a cooling heat exchanger and a heating heat exchanger. The cooling heat exchanger is located upstream of the blower inside the case. The heating heat exchanger is located downstream of the blower inside the case. The ventilation passage includes a before-heating passage extending from an air discharge port of the blower toward an air inlet of the heating heat exchanger. The before-heating passage includes, as a part of the before-heating passage, a flow-changing path that is curved to change a flow direction of the air discharged from the blower.

In the application, since the flow of air outside the vehicle compartment flowing through the upstream heat exchange part and the flow of air outside the vehicle compartment flowing through the downstream heat exchange part are opposite flows, a second heat exchanger through which the air outside the vehicle compartment flowing from the first fan through the downstream heat exchange part flows, a first heat exchanger is an orthogonal heat exchanger, the second heat exchanger that is a component of a refrigeration cycle execution system, the air in the vehicle compartment, which flows in from the inside air inlet by the rotation of the second fan and is discharged from the outlet outside the vehicle through the first heat exchanger, and the air outside the vehicle compartment, are exchanged with the first heat exchanger, it can be miniaturized along with the improvement of electricity cost.

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.

A valve manifold integration module for a thermal management system is provided. The thermal management system has multiple preset thermal management modes. The valve manifold integration module includes: multiple flow channels, disposed inside the valve manifold integration module; and a valve manifold, including multiple valves. The valves are disposed on the valve manifold integration module. The valves communicate with the flow channels. The multiple flow channels are communicated with each other via the valves to form fluid channels, to realize at least one of the thermal management modes.

Disclosed herein is a heat pump system for a vehicle which includes an evaporator mounted on a cold air passageway inside an air-conditioning case, a condenser mounted on a warm air passageway, a first blower mounted at an inlet side of the cold air passageway of the air-conditioning case, a second blower mounted at an inlet side of the warm air passageway and an intake duct mounted between the first blower and the second blower to supply indoor air and outdoor air to the first blower and the second blower respectively, thereby maximizing space efficiency because using just one intake duct for the two blowers, and reducing the size and manufacturing costs of the heat pump system.

An HVAC system includes an evaporator, a heater, a plurality of outlets, and a sliding control door downstream of the evaporator, which is configured to allow air to flow across one or both of a heated path across the heater and a bypass path bypassing the heater. A sliding stratification door is downstream of the temperature control door and positionable to, in an intermediate position, direct air flowing through the bypass path to be mixed with air that flowed across the heated path before flowing out of the plurality of outlets.

An electric vehicle having a heat exchanger formed in an aerodynamic airfoil shape comprising one or more body panels disposed along an outer surface of the vehicle having one or more fluidic chambers or micro-channels. The heat exchanger is adapted to provide effective and highly efficient heat transfer, and also to provide substantially reduced or negligible contribution to the aerodynamic drag. The heat exchanger includes a supplemental heat exchange system wherein at least a portion of the heat exchange capacity is provided by an inner heat exchange surface of the heat exchanger exposed to an interstitial space within the vehicle. Airflow is forced, via a fan for example, from an aerodynamically-efficient inlet, over the inner heat exchange surface, and exhausted through an aerodynamically-efficient outlet, thereby providing a supplemental heat exchange system including substantially reduced or negligible contribution to the aerodynamic drag.
