Description

Cooling module
Technical Field
The present invention relates to a cooling module, and particularly to a cooling module including an engine radiator for cooling an engine of a hybrid vehicle, an electric radiator for cooling a driving motor, and a condenser for cool air supply of the vehicle.
Background
In general, a hybrid vehicle is a vehicle that obtains driving force by mounting an engine and a motor and driving them simultaneously or selectively.
Such a hybrid vehicle is driven by a motor during constant speed running and initial driving, and is driven by an internal combustion engine during hill climbing or a battery discharge mode, thereby improving fuel economy.
Here, the motor and the electric components such as the battery for driving the motor generate heat during operation, and a cooling device for suppressing the temperature rise of the components is required to maintain the input and output characteristics of the components at the highest level. Therefore, heat generated during the operation of the motor and heat generated by the charge and discharge of the battery should be maintained at appropriate temperatures by the cooling device.
Therefore, the cooling system of the hybrid vehicle is configured to be able to cool both the cooling system of the engine and the electric cooling system, which are two power sources.
As shown in fig. 1, the hybrid cooling module 10 includes an engine radiator 20 and an electric radiator 30, and may include a condenser 40 of an air conditioning system for supplying cold air in a vehicle interior.
However, the cooling module of the hybrid vehicle to which the turbocharger is applied is configured by arranging a condenser, an electric radiator, and an engine radiator in 3 rows along a flow direction of cooling air, and arranging an intercooler for cooling high-temperature air compressed by the turbocharger below the heat exchangers of the 3 rows. In this case, when the condenser is disposed at the forefront in the cooling air flow direction and the electric radiator is disposed at the rear thereof, the cooling of the electric components is adversely affected, and conversely, when the electric radiator is disposed at the forefront in the cooling air flow direction and the condenser is disposed at the rear thereof, the performance of the air conditioner is adversely affected.
Therefore, it is necessary to optimize the arrangement and structure of the heat exchanger and to satisfy the structures of the two cooling modules at the same time.

As shown, the cooling module 1000 of an embodiment of the present invention may include: a condenser 100, comprising: a condensation region 100-1 in which the refrigerant flows and is cooled, and the gaseous refrigerant is converted into a liquid refrigerant in the condensation region 100-1; and a supercooling region 100-2 in which the liquid refrigerant liquefied by the condensation region 100-1 flows and is supercooled; and an electric radiator 200 disposed in front of the condenser 100 in a flow direction of the cooling air, on a side of the condensing region 100-1 of the condenser 100, so as not to overlap the supercooling region 100-2 of the condenser 100.
The condenser 100 is a heat exchanger as follows: in an air conditioning system for supplying cold air to a vehicle interior, a high-temperature and high-pressure refrigerant in a gas state flows into the system, and the heat of liquefaction is released to condense the refrigerant into a refrigerant in a liquid state, and then the refrigerant is discharged. The condenser 100 may be composed of a pair of header tanks 110, a plurality of tubes 120, a plurality of fins 130, and a gas-liquid separator 160. An inlet portion 140 into which the refrigerant flows and an outlet portion 150 from which the refrigerant is discharged may be formed in the header tank 110, and a partition plate dividing an internal space may be formed in the header tank 110. Thus, the condenser 100 may be formed as follows: the gaseous refrigerant flows in through the inlet part 140, is cooled by passing through the condensation area 100-1 partitioned by the partition, is converted into a liquid refrigerant, and then flows into the supercooling area 100-2 only with passing through the gas-liquid separator 160, and the inflowing liquid refrigerant is supercooled by passing through the supercooling area 100-2 and then discharged from the outlet part 150. At this time, as the liquid refrigerant is supercooled in the supercooling region 100-2, enthalpy (enthalpy) of the refrigerant can be further reduced, and cooling efficiency can be improved.
The electric radiator 200 is a heat exchanger that cools a heat exchange medium for cooling electric components such as a motor for a hybrid vehicle or an electric vehicle and a battery for driving the motor. The electric radiator 200 may be composed of a pair of header tanks 210, a plurality of tubes 220, and a plurality of fins 230. An inlet 240 through which the heat exchange medium flows in and an outlet 250 through which the heat exchange medium is discharged may be formed in the header tank 210, and a partition plate for partitioning an inner space may be formed in the header tank 210. Thus, the electric heat sink 200 may be formed in the following structure: the heat exchange medium flows in through the inlet portion 240, flows along a path of the heat exchange medium divided by the partition plates, is cooled, and is discharged through the outlet portion 250.
Here, the electric radiator 200 may be disposed in parallel in front of the condenser 100 in a flow direction of the cooling air, and the electric radiator 200 may be disposed within a range of the condensation area 100-1 in which the condenser 100 is formed in a height direction and a length direction, so that the electric radiator 200 is disposed not to overlap the supercooling area 100-2 of the condenser 100.
Thus, in cooling module 1000 according to an embodiment of the present invention, electric radiator 200 and condenser 100 are arranged along the flow direction of the cooling air, and the air that has passed through electric radiator 200 among the cooling air flowing in from the front of cooling module 1000 passes through condensation area 100-1 of condenser 100, and the air that has not passed through electric radiator 200 among the cooling air passes through supercooling area 100-2 of condenser 100.
The relatively cool cooling air before being heated by performing the heat exchange can directly pass through the electric radiator, thereby ensuring the cooling performance of the electric radiator, and the relatively cool cooling air before being heated by performing the heat exchange can directly pass through the supercooling region of the condenser, thereby ensuring the cooling performance of the condenser.
The condenser 100 may include a pair of header tanks 110 spaced apart in a height direction, a plurality of tubes 120 connected at both ends to the pair of header tanks 110 and through which a refrigerant flows, and a plurality of fins 130 interposed between the tubes 120, the condensing region 100-1 may be formed at one side in a length direction, and the supercooling region 100-2 may be formed at the other side in the length direction.
That is, referring to fig. 3, the condenser 100 may be generally composed of a pair of header tanks 110, a plurality of tubes 120, a plurality of fins 130, and a gas-liquid separator 160, an inlet portion 140 into which a refrigerant flows and an outlet portion 150 from which the refrigerant is discharged may be formed in the header tank 110, and a partition plate dividing an internal space may be formed in the header tank 110. Here, the pair of header tanks 110 may be arranged in parallel with a vertical interval therebetween, and upper and lower ends of the pipe 120 are connected to the pair of header tanks 110. Thus, the condenser 100 may be formed in a down flow type in which the direction of the refrigerant passing through the tubes 120 is formed in a height direction, and the condensing region 100-1 may be formed at one side (left side) in a length direction and the supercooling region 100-2 may be formed at the other side (right side). In addition, electric radiator 200 may be disposed at a position corresponding to condensation area 100-1 of condenser 100 in the longitudinal direction so as not to shield supercooling area 100-2 of condenser 100. This can prevent the heat exchange area of the electric radiator 200 from decreasing in the height direction, and can realize more effective arrangement of the electric radiator.
Further, an engine radiator 300 disposed behind the condenser 100 may be further included in the flow direction of the cooling air.
That is, as shown in the drawing, cooling module 1000 according to the present invention may further include engine radiator 300 disposed behind condenser 100, and electric radiator 200, condenser 100, and engine radiator 300 may be arranged in this order in the width direction, which is the flow direction of the cooling air, and may be disposed in parallel to each other. Here, engine radiator 300 is a heat exchanger that cools cooling water, which is a heat exchange medium for cooling the engine. Engine radiator 300 may include a pair of header tanks 310 arranged at a distance in the longitudinal direction, a plurality of tubes 320 connected at both ends to the pair of header tanks 310 and through which a heat exchange medium flows, and a plurality of fins 330 interposed between tubes 320. An inlet 340 into which the heat exchange medium flows and an outlet 350 from which the heat exchange medium is discharged may be formed in the header tank 310, and a partition plate dividing an inner space may be formed in the header tank 310. Thus, engine radiator 300 may be formed as follows: the cooling water flows in through the inlet portion 340, flows along a flow path divided by the partition, is cooled, and is discharged through the outlet portion 350.
The condenser 100 may further include a gas-liquid separator 160 connected to the refrigerant outlet of the condensation area 100-1 and the refrigerant inlet of the supercooling area 100-2, and the gas-liquid separator 160 may be disposed on one side of the supercooling area 100-2 in the longitudinal direction and outside the area in which the engine radiator 300 is disposed in the height direction and the longitudinal direction.
That is, the gas-liquid separator 160 is a device that separates the gas refrigerant and the liquid refrigerant and allows only the liquid refrigerant to flow into the supercooling region 100-2, and an inlet of the gas-liquid separator 160 may be connected to a refrigerant outlet of the condensation region 100-1 and an outlet of the gas-liquid separator 160 may be connected to a refrigerant inlet of the supercooling region 100-2. Further, gas-liquid separator 160 is disposed on the left side of supercooling region 100-2 in the longitudinal direction and outside the region in the height direction and the longitudinal direction in which engine radiator 300 is disposed, whereby flow resistance to the cooling air flowing from the front to the rear and passing through engine radiator 300 can be reduced.
In the electric radiator 200, an inlet 240 into which the heat exchange medium flows and an outlet 250 from which the heat exchange medium is discharged are formed in a longitudinal direction on the opposite side of the supercooling region 100-2 in which the condenser 100 is disposed.
That is, as shown in the drawing, when the supercooling region 100-2 of the condenser 100 is disposed at the left side in the longitudinal direction, the inlet 240 and the outlet 250 of the electric radiator 200 are formed at the right side, and the tubes constituting the inlet 240 and the outlet 250 can be made not to block the front side of the supercooling region 100-2. This makes it possible to easily dispose inlet 240 and outlet 250 in electric radiator 200 without increasing the flow resistance of the cooling air.
In this case, the electric radiator 200 may include a pair of header tanks 210 spaced apart in a longitudinal direction, a plurality of tubes 220 connected at both ends to the pair of header tanks 210 and through which a refrigerant flows, and a plurality of fins 230 interposed between the tubes 220, and the inlet portion 240 and the outlet portion 250 may be formed at one side in the longitudinal direction.
That is, header tank 210 of electric radiator 200 is disposed on both sides in the longitudinal direction, inlet 240 and outlet 250 are easily formed in header tank 210, and the length of the pipe constituting inlet 240 and outlet 250 can be made short. At this time, the electric radiator 200 may be formed in a U-flow type in which the direction of the refrigerant passing through the tubes 220 is formed in a longitudinal direction, and the header tank 210 is divided by a partition plate, and the heat exchange medium flowing into the inlet portion 240 moves from the left side to the right side in the longitudinal direction by U-turning after flowing from the right side to the left side in the longitudinal direction, and is discharged through the outlet portion 250.
Further, an intercooler 400 may be further provided, and the intercooler 400 may be disposed in front of the engine radiator 300 in the flow direction of the cooling air.
The intercooler 400 is a heat exchanger that cools air compressed to high temperature and high pressure by a turbocharger, and the intercooler 400 may be disposed on the front side of the engine radiator 300. Here, the intercooler 400 may include a pair of header tanks 410 arranged to be spaced apart in the longitudinal direction, a plurality of tubes 420 having both ends connected to the pair of header tanks 410 and through which a heat exchange medium flows, and a plurality of fins 430 interposed between the tubes 420.
