Abstract

A cooling module for a vehicle includes: a high temperature radiator including first and second header tanks into which a coolant flows and from which it is exhausted, and a plurality of tubes and heat radiating fins respectively interconnecting the first and second header tanks; a low temperature radiator including third and fourth header tanks into which a coolant flows and from which it is exhausted, and a plurality of tubes and heat radiating fins respectively interconnecting the third and fourth header tanks; and a condenser disposed at a side surface of the high temperature and low temperature radiators corresponding to the second and fourth header tanks to be respectively connected to the second and fourth header tanks and condensing a refrigerant flowing therein through heat exchange with a coolant supplied from the second and fourth header tanks.

First claim

What is claimed is:

1. A cooling module for a vehicle, comprising:
a high temperature radiator including: a first header tank into which a first coolant flows, a second header tank from which the first coolant is discharged, and a plurality of first tubes and a plurality of first heat radiating fins respectively interconnecting the first header tank and the second header tank;
a low temperature radiator including: a third header tank into which a second coolant flows, a fourth header tank from which the second coolant is discharged, and a plurality of second tubes and a plurality of second heat radiating fins respectively interconnecting the third header tank and the fourth header tank; and
a condenser disposed at a side surface of the high temperature and low temperature radiators corresponding to the second and fourth header tanks to be respectively connected to the second and fourth header tanks, the condenser configured to condense a refrigerant flowing therein through heat exchange with the first coolant and second coolant respectively discharged from the second and fourth header tanks.

2. The cooling module for the vehicle of claim 1 , wherein
the condenser includes:
a first heat radiating unit connected to the second header tank through a first inflow pipe and a first exhaust pipe, which are respectively provided at positions on a rear surface of the condenser and configured to circulate the first coolant supplied from the high temperature radiator; and
a second heat radiating unit integrally formed with the first heat radiating unit, connected to the fourth header tank through a second inflow pipe and a second exhaust pipe, which are respectively provided on a front surface of the condenser, and configured to circulate the second coolant supplied from the low temperature radiator,
the first heat radiating unit and the second heat radiating unit respectively include a plurality of plates configured to form a plurality of flow channels for the refrigerant, the first coolant, and the second coolant.

3. The cooling module for the vehicle of claim 2 , wherein,
a refrigerant inlet is formed at a rear upper surface of the condenser, and a refrigerant outlet is formed at a lower portion of the condenser and separated from the refrigerant inlet in a diagonal direction.

4. The cooling module for the vehicle of claim 3 , wherein
the condenser condenses a refrigerant flowing in through the refrigerant inlet through heat exchange with the first coolant and second coolant while sequentially passing through the first heat radiating unit and the second heat radiating unit, and the condenser exhausts the condensed refrigerant through the refrigerant outlet.

5. The cooling module for the vehicle of claim 2 , wherein
the first inflow pipe is disposed at an upper portion based on a length direction of the condenser,
the first exhaust pipe is disposed below the first inflow pipe, and
the second inflow pipe is disposed at a position lower than the second exhaust pipe in the length direction of the condenser.

6. The cooling module for the vehicle of claim 2 , wherein
the first heat radiating unit condenses the refrigerant of a gaseous state by using the first coolant supplied from the high temperature radiator.

7. The cooling module for the vehicle of claim 2 , wherein
the second heat radiating unit includes:
a main heat radiating unit secondarily condensing the refrigerant, which is first condensed while passing through the first heat radiating unit, into a gaseous and liquid mixed state; and
a sub-heat radiating unit disposed at a lower portion of the main heat radiating unit in a length direction of the condenser and configured to further condense the refrigerant that is secondarily condensed while passing through the main heat radiating unit.

8. The cooling module for the vehicle of claim 7 , wherein
the coolant supplied from the fourth header tank first passes through the sub-heat radiating unit and is exhausted to the fourth header tank after passing through the main heat radiating unit.

9. The cooling module for the vehicle of claim 7 , wherein
the main heat radiating unit is connected to the sub-heat radiating unit through a receiver drier, and the receiver drier separates moisture from the condensed refrigerant.

10. The cooling module for the vehicle of claim 9 , wherein
the receiver drier is disposed outside the second heat radiating unit.

11. The cooling module for the vehicle of claim 9 , wherein
the receiver drier is disposed between the main heat radiating unit and the sub-heat radiating unit.

12. The cooling module for the vehicle of claim 2 , wherein
the second heat radiating unit is disposed below the first heat radiating unit, and is partitioned from the first heat radiating unit to inhibit or prevent mixing of the first and second coolants inside the condenser.

13. The cooling module for the vehicle of claim 1 , wherein
the condenser is a water-cooled plate heat exchanger in which a plurality of plates are stacked on one another and formed.

14. The cooling module for the vehicle of claim 1 , wherein
a cooling fan is provided at a rear of the high temperature radiator.

15. The cooling module for the vehicle of claim 1 , wherein
the low temperature radiator is disposed at a front of the high temperature radiator.
