Cooling module for vehicle

Abstract

A cooling module for a vehicle may include a main radiator, a sub-radiator, a water-cooled condenser and an air-cooled condenser. The main radiator may be disposed at a front region of an engine room and supplies cooled cooling water to an engine. The sub-radiator may be disposed substantially in parallel with the main radiator and in front of the main radiator, have header tanks at both sides and supply the cooled cooling water to an intercooler or electric components. The water-cooled condenser may be disposed in one of the header tanks and primarily condenses a refrigerant by using the cooling water as a heat exchange medium. The air-cooled condenser may be in fluidic communication with the water-cooled condenser to be introduced with the refrigerant condensed in the water-cooled condenser and may be disposed in front of the sub-radiator to secondarily condense the refrigerant.

Problems solved by technology

[0008] Here, in the cooling module for vehicles according to the related art, when the condenser is cooled with water, the cooling water and the refrigerant exchange heat, so the outlet refrigerant temperature of the condenser increases, thus increasing the required power

[0009] In addition, the water-cooled condenser has a larger cooling water heat capacity than the air-cooled type condenser, so that the water-cooled condenser has a low condensation pressure but reduces the temperature difference between the cooling water and the refrigerant and has a higher than The cooling water temperature of the outside air makes it difficult for the water-cooled condenser to form secondary cooling, thus reducing the overall cooling performance of the air conditioner system

[0010] To avoid this, large capacity cooling fans and radiators are required, which can adversely affect the layout of the narrow engine compartment and the overall weight and cost of the vehicle

[0011] In addition, in order to install the water-cooling condenser in a narrow engine compartment, the water-cooling condenser needs to be installed at the rear area of ​​the fender or at the rear area of ​​the engine compartment, so it is difficult to secure the space, so that the connecting pipes and arrangement layout may be complicated and Assembling performance and installation performance may be deteriorated, and thermal damage to the engine compartment may cause performance degradation, thus causing an increase in power consumption of the compressor due to an increase in the flow resistance of the refrigerant

[0012] Furthermore, in the case of an eco-friendly vehicle using a motor, an electric drive element, an exhaust stack, etc., cooling water cools each element and is then introduced into the condenser, so its temperature increases so that the condensation amount of the refrigerant may be greatly increased. reduce

[0013] In addition, it is difficult to secure space to install the cooling module between the narrow engine compartment and the bumper, and the heat capacity and operating temperature of the radiator and air conditioner condenser are different, so that when the cooling is uniformly performed by the cooling fan and the flowing wind, due to There is a problem that the cooling performance of the vehicle and the indoor cooling efficiency decrease due to a difference in cooling performance, and there may be a problem that the driving distance may decrease due to an increase in energy used by cooling fans and water pumps, etc.
