## Abstract

The present invention provides an air conditioning system for a vehicle, which includes an evaporator mounted in a cold air passageway and a condenser mounted in a warm air passageway inside an air-conditioning case to perform cooling and heating, and protecting means for surrounding a plurality of electronic units mounted on the outer surfaces of the air-conditioning case and blowers, thereby preventing breakdowns and malfunctions by preventing foreign matters or water from entering into the electronic units.

## Claims

### Claim 1

An air conditioning system for a vehicle comprising:
a blower unit mounted at an inlet of an air-conditioning case and including a first blower and a second blower in coaxial alignment with one another, an air inlet positioned axially between the first and second blowers, and indoor and outdoor air converting doors for selectively allowing the blower unit to blow indoor or outdoor air;
the blower unit having a first outer surface and a second outer surface extending generally perpendicularly to one another;
the first blower having a motor installed on the first outer surface of the blower unit to operate the first blower;
cable connectors coupled with and extending from the at least one motor;
at least one actuator installed on the second outer surface of the blower unit to operate the indoor and outdoor air converting doors;
a protecting cover mounted on the first and second outer surfaces of the blower unit, the protecting cover being a single integral cover having a first cover part surrounding the cable connectors and overlying the first outer surface of the blower unit, and a second cover part extending generally perpendicularly to the first cover part and from the first cover part and surrounding the actuator and overlying the second outer surface of the blower unit.

### Claim 2 (depends on 1)

The air conditioning system according to claim 1, wherein the protective cover is formed to surround the at least one actuator and sensor connectors that connect to a sensor installed inside the blower unit.

### Claim 3 (depends on 1)

The air conditioning system according to claim 1, wherein a seal is mounted between the outer surface of the blower unit and the protective cover.

### Claim 4 (depends on 1)

The air conditioning system according to claim 1, wherein the protective cover has a receiving part for receiving the cable connectors, and
wherein a through hole, through which cables of the cable connectors pass, is formed at one side of the protective cover.

### Claim 5 (depends on 1)

The air conditioning system according to claim 1, wherein a screw connecting part is formed on the protective cover to connect the protective cover to the outer surface of the blower unit by a screw.

### Claim 6 (depends on 1)

The air conditioning system according to claim 1, wherein the air-conditioning case and the blower unit are arranged in an engine room of the vehicle.

### Claim 7 (depends on 1)

The air conditioning system according to claim 1, wherein the air-conditioning case comprises a cold air passageway on which an evaporator is mounted, and a warm air passageway on which a condenser is mounted.

### Claim 8

An air conditioning system for a vehicle comprising:
a blower nit mounted at an inlet of an air-conditioning case and including a first blower and a second blower in coaxial alignment with one another and an air inlet positioned axially between the first and second blowers, and indoor and outdoor air converting doors for selectively allowing the blower unit to blow indoor or outdoor air;
the first blower having a first motor and the second blower having a second motor with the first and second blower motors axially aligned with one another;
first cable connectors extending from the first blower and second cable connectors extending from the second motor;
a first actuator and a second actuator each overlying the air inlet axially between the first and second motors, the first and second actuators for operating the indoor and outdoor air converting doors; and
a first protecting cover generally having an L-shape and having a first cover part overlying and surrounding the first cable connectors and a second cover part extending from the first cover part and perpendicularly to the first cover part and overlying and surrounding the first actuator, and a second protecting cover generally having an L-shape and having a third cover part overlying and surrounding the second cable connectors and a fourth cover part extending from the third cover part and extending perpendicularly to the third cover part and overlying and surrounding the second actuator.
