Hybrid intercooler system and control method thereof

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.
