Abstract: The present disclosure provides an EGR cooler for a vehicle. The EGR cooler includes: a gas passage having a predetermined length, the gas passage including a linear part forming a linear section and extension parts extending from opposite ends of the linear part after being bent; a heat radiation fin having a shape formed by being folded several times, the heat radiation fin being placed in the linear section of the gas passage; and a base provided with an inlet hole at a first end and an outlet hole at a second end. In particular, the inlet hole and the outlet hole each has a shape corresponding to a cross-section of the gas passage, and the extension parts are inserted into the inlet hole and the outlet hole, respectively.

Abstract: A method for controlling a cooling system for a vehicle is provided. The system includes an engine, an EGR cooler, an oil cooler, a heater, a radiator, and a controller. The engine, the EGR cooler, the oil cooler, the heater, and the radiator are respectively connected through a coolant line and coolant circulates through the engine, the EGR cooler, the oil cooler, the heater, and the radiator by operation of a water pump. The controller receives the coolant from the engine and operates a control valve connected with the oil cooler, the heater, and the radiator. The method includes: sensing driving conditions and operating the control valve when a cooling mode is required to decrease the temperature within the vehicle based on the sensed driving conditions. The control valve is operated based on modes controlled depending on a coolant temperature, and among the plurality of modes, one is iteratively performed.

Abstract: An integrated exhaust gas recirculation (EGR) cooler includes a cooling core allowing an exhaust manifold and an intake manifold to be in communication with each other and an integrated housing having the cooling core inserted thereinto. The integrated housing is provided with a first exhaust port exhausting a coolant introduced thereinto only when a thermo-sensitive device mounted in the integrated housing is operated and a second exhaust port always exhausting the coolant introduced thereinto. An amount of the coolant introduced into an EGR cooler is maximized. Therefore, cooling efficiency may be maximized, and a size of the cooling core may be decreased.

Abstract: A method of controlling a cooling system for a hybrid electric vehicle can include measuring an outside air temperature, determining whether the measured outside air temperature is within a preset low-temperature environment temperature range, determining, in a case where a determination is made that the outside air temperature is within the low-temperature environment temperature range, whether a vehicle state corresponds to a preset heating mode, detecting, in a case where a determination is made that the vehicle state does not correspond to the heating mode, a coolant temperature, and controlling, in a case where a determination is made that the coolant temperature detected by a coolant temperature measurement unit is within a preset target temperature range, opening and closing of a control valve by the controller to selectively perform a coolant flow stop control in a low-temperature environment.
