Hybrid intercooler system and control method thereof

1. A hybrid intercooler system, comprising:

an air cooler configured to exchange heat with exterior air passing through an outer wall of a plurality of compressed intake air paths to cool a compressed intake air passing through the inside of the compressed intake air paths;

a water cooler configured to exchange heat between a water cooler coolant enclosing the outer wall of the compressed intake air paths and the compressed intake air cooled in the air cooler, wherein the water cooler includes a water cooler coolant tank that encloses the compressed intake air paths; and

a bypass line configured to be branched from a receiver drier, pass through the water cooler coolant tank, and communicate with a condensation line that connects a compressor and an air-conditioner condenser.

2. The hybrid intercooler system of claim 1 , wherein the bypass line is disposed to penetrate through between the compressed intake air paths and an inner wall of the water cooler coolant tank.

3. The hybrid intercooler system of claim 2 , wherein the bypass line is branched into a plurality of lines in a section in which the bypass line penetrates through between the compressed intake air paths and the inner wall of the water cooler coolant tank.

4. The hybrid intercooler system of claim 1 , further comprising:

a bypass valve installed on the bypass line to open or close the bypass line.

5. The hybrid intercooler system of claim 4 , further comprising:

a water cooler coolant circulation pump installed on the bypass line at a back part of the bypass valve to exhaust an air-conditioner coolant in the bypass line to the condensation line.

6. The hybrid intercooler system of claim 1 , further comprising:

an expansion line configured to provide communication between the receiver drier and an expansion valve.

7. The hybrid intercooler system of claim 6 , further comprising:

an evaporation line configured to provide communication between the expansion valve and a heating core.

8. The hybrid intercooler system of claim 7 , further comprising:

a compression line configured to provide communication between the heating core and the compressor.

9. The hybrid intercooler system of claim 8 , further comprising:

a gas-liquid separation line configured to provide communication between the air-conditioner condenser and the receiver drier.

10. The hybrid intercooler system of claim 1 , wherein the water cooler coolant tank includes a water cooler coolant inlet that protrudes from an upper surface thereof.

11. The hybrid intercooler system of claim 10 , wherein the water cooler coolant tank further includes a water cooler coolant cap configured to open and close the water cooler coolant inlet.

12. A control method of a hybrid intercooler system, including an air cooler configured to exchange heat with exterior air passing through an outer wall of a plurality of compressed intake air paths to cool a compressed intake air passing through the inside of the compressed intake air paths; a water cooler configured to exchange heat between a water cooler coolant enclosing the outer wall of the compressed intake air paths and the compressed intake air cooled in the air cooler wherein the water cooler includes a water cooler coolant tank that encloses the compressed intake air paths; a bypass line configured to be branched from a receiver drier, pass through the water cooler coolant tank, and communicate with a condensation line that connects a compressor and an air-conditioner condenser; a bypass valve installed on the bypass line to open or close the bypass line; and a water cooler coolant circulation pump installed on the bypass line at a back part of the bypass valve to exhaust an air-conditioner coolant in the bypass line to the condensation line, the method comprising:

measuring, by a controller, a temperature of an intake air at an outlet of the hybrid intercooler system using a sensor;

determining, by the controller, whether the measured temperature of the intake air is greater than a preset reference temperature; and

opening, by the controller, the bypass valve and operating the water cooler coolant circulation pump when the measured temperature of the intake air is greater than the preset reference temperature.

13. The control method of claim 12 , further comprising:

closing, by the controller, the bypass valve and stopping the operation of the water cooler coolant circulation pump when the measured temperature of the intake air is less than the preset reference temperature.
