Abstract

An air conditioning system of a high voltage battery for a vehicle and an air conditioning method using the same include a first heat exchanger arranged in a housing of the high-voltage battery and a first blower for blowing air around the first heat exchanger. A second heat exchanger is arranged on an external upper part of the housing of the high-voltage battery, and a second blower blows air around the second heat exchanger. A first surface of a Peltier cooler is in contact with the second heat exchanger. Cooling water circulates through a cooling line, and a first part of which is in contact with a second surface of the Peltier cooler extending downward, and a second part of the cooling line is connected to the first heat exchanger to exchange heat.

Claims

1. An air conditioning system of a high voltage battery for a vehicle, the system comprising:

a first heat exchanger arranged in a housing of the high-voltage battery and a first blower for blowing air around the first heat exchanger;

a second heat exchanger arranged on an external upper part of the housing of the high-voltage battery and a second blower for blowing air around the second heat exchanger;

a Peltier cooler a first surface of which is connected and in contact with the second heat exchanger; and

a cooling line through which cooling water circulates, the cooling line having a first part of which is connected and in contact with a second surface of the Peltier cooler extending downward, and a second part of which is connected to the first heat exchanger to exchange heat.

2. The air conditioning system of claim 1, wherein the housing of the high-voltage battery is arranged in a trunk room and the first blower discharges waste heat to the inside of the trunk room, and an air extractor is provided in the trunk room.

3. The air conditioning system of claim 1, wherein the housing of the high-voltage battery has a closed-structure and the first heat exchanger and the first blower are arranged inside the housing to air-condition internal air of the housing, and the second part of the cooling line is inserted through the housing to connect to the first heat exchanger.

4. The air conditioning system of claim 1, wherein the cooling line is a cooling water pipe without having a separate driver.

5. The air conditioning system of claim 1, wherein a plurality of radiation fins through which the heat is exchanged with the air are provided on the first heat exchanger and the second heat exchanger.

6. The air conditioning system of claim 1, further comprising a controller for controlling operations of the first blower, the second blower, and the Peltier cooler.

7. The air conditioning system of claim 6, wherein the controller operates the first blower and the second blower when a low level cooling of the high-voltage battery is required.

8. The air conditioning system of claim 6, wherein the controller operates all of the first blower, the second blower, and the Peltier cooler when a high level cooling of the high-voltage battery is required.

9. An air conditioning method of a high voltage battery for a vehicle using the air conditioning system of claim 1, the method comprising;

a mode determining step for determining an air conditioning mode that is required for the high voltage battery; and

a high level cooling step for operating the first blower and the second blower in the case of a high level cooling mode, and controlling the Peltier cooler to be cooled on the first surface thereof.

10. The air conditioning method of a high voltage battery for a vehicle of claim 9, further comprising a low level cooling step for operating only the first blower and the second blower in case of a low level cooling mode, after the mode determining step.
