Abstract
An intercooler cooling apparatus is provided. The apparatus cools an intercooler installed between a compressor of a turbocharger and an engine to adjust an oil temperature. The apparatus includes a water tank that surrounds a part of an outer side of the intercooler, in which cooling water discharged from the engine flows into a first side to exchange heat with the intercooler and the cooling water is discharged through a second side. An ATF warmer and an air conditioner refrigerant line are also installed in the water tank, in which oil of a transmission is circulated.
Claims19
An intercooler cooling apparatus cooling an intercooler installed between a compressor of a turbocharger and an engine, capable of adjusting an oil temperature, comprising:
- a water tank that surrounds a part of an outer side of the intercooler, in which cooling water discharged from the engine flows into a first side to exchange heat with the intercooler and the cooling water is discharged through a second side;
- and
- an automatic transmission fluid (ATF) warmer installed in the water tank, in which oil of a transmission is circulated.
A method for controlling an intercooler cooling apparatus capable of controlling an oil temperature, which includes a water tank that surrounds a part of an outer side of the intercooler, in which cooling water discharged from the engine flows into a first side to exchange heat with the intercooler and the cooling water is discharged through a second side, a fluid tank in which a heat exchange fluid filled in the fluid tank exchanges heat with air flowing through the intercooler while refrigerant of an air conditioner passes through the fluid tank at a location spaced apart from the water tank in the intercooler, and an automatic transmission fluid (ATF) warmer installed in the water tank, in which oil of a transmission is circulated, the method comprising:
- measuring, by a plurality of sensors, an oil temperature of the transmission, a temperature of the cooling water, and an outlet temperature of the intercooler;
- comparing, by the controller, whether the temperature of the oil of the transmission is greater than a preset oil heating reference temperature by which the transmission oil needs to be heated;
- operating, by the controller, a cooling water pump when the temperature of the oil of the transmission is greater than the oil heating reference temperature;
- comparing, by the controller, whether the outlet temperature of the intercooler is greater than a preset refrigerant circulation reference temperature by circulating the refrigerant of the air conditioner;
- and
- operating, by the controller, a refrigerant pump when the outlet temperature of the intercooler is greater than the refrigerant circulation reference temperature.
