Abstract

Provided is a radiator and condenser assembly, and more particularly, a radiator and condenser assembly capable of forming a pair of protrusions for horizontally fixing the condenser at a lower portion of a header tank of the radiator and forming a fixed part in a ‘U’ shape for fixing the condenser in a front and back direction to directly fix a vapor-liquid separator of the condenser to the header tank of the radiator to remove a fixed bracket formed in the condenser, thereby saving component manufacturing costs and additional process and processing costs for forming the fixed bracket.

First claim

The invention claimed is:

1. A radiator and condenser assembly, comprising:
a radiator including a first header tank and a second header tank, a plurality of first tubes having a first end fixed to the first header tank and a second end fixed to the second header tank, first fins inserted between the first tubes, and a fixed part formed at a lower portion of the second header tank; and
a condenser including a third header tank and a fourth header tank, a plurality of second tubes having a first end fixed to the third header tank and a second end fixed to the fourth header tank to form a refrigerant passage, second fins inserted between the second tubes, and a vapor-liquid separator connected to the fourth header tank to separate a vapor refrigerant and a liquid refrigerant, wherein air flows through the radiator and the condenser in series while flowing in a first direction, wherein the fixed part of the radiator includes a pair of fixed protrusions protruding from the second header tank and a fixed bracket extending from the second header tank,
wherein the pair of fixed protrusions protrude from the second header tank in the first direction and are spaced apart from each other in a second direction arranged perpendicular to the first direction,
wherein the fixed bracket includes a horizontal part extending from the second header tank in the first direction and a vertical part extending from an end portion of the horizontal part in a third direction arranged perpendicular to the first direction and the second direction, the vertical part spaced apart from the pair of fixed protrusions and the second header tank with respect to the first direction,
wherein a lower portion of the vapor-liquid separator of the condenser is inserted into the fixed part of the radiator in the third direction to be coupled to the radiator,
wherein at least three positions on an outer circumferential surface of the vapor-liquid separator are in contact with the pair of fixed protrusions and the vertical part, respectively, thereby enabling the pair of fixed protrusions and the vertical part to fix movement of the vapor-liquid separator in the first direction and the second direction, and
wherein a lowermost surface of the vapor-liquid separator with respect to the third direction is supported on and contacts the horizontal part of the fixed bracket,
wherein the horizontal part of the fixed bracket is formed beneath the pair of fixed protrusions in the third direction, and the vertical part of the fixed bracket extends upwardly from the horizontal part in the third direction towards the pair of fixed protrusions,
wherein an upper portion of the second header tank is provided with an upper coupling part and, at a position corresponding to the upper coupling part, the condenser is provided with an upper bracket to allow the upper bracket to be inserted into the upper coupling part downwardly from the upper portion in the third direction, and
wherein a portion of the horizontal part that is in contact with the vapor-liquid separator is disposed between the end portion of the horizontal part and the second header tank.

2. The radiator and condenser assembly of claim 1 , wherein the vertical part of the fixed bracket includes a cut part in a ‘C’ shape and a support part that protrudes towards the second header tank.

3. The radiator and condenser assembly of claim 2 , wherein an upper end of an inside of the vertical part and the support part is provided with an inclined part.

4. The radiator and condenser assembly of claim 3 , wherein in the fixed part, a distance H from an upper side surface of one of the fixed protrusions of the pair of fixed protrusions to an upper end of the support part is within 30 mm.

5. The radiator and condenser assembly of claim 1 , wherein in the fixed bracket, an ‘L’-shaped inside or an outside is provided with a reinforcement rib.

6. The radiator and condenser assembly of claim 1 , wherein in the fixed part, a height of the pair of fixed protrusions is higher than that of an upper end of the vertical part.

7. The radiator and condenser assembly of claim 6 , wherein the fixed part is integrated with the second header tank by an injection molding.

8. The radiator and condenser assembly of claim 1 , wherein the first header tank, the second header tank, and the first tubes, the first fins, and the fixed part of the radiator are disposed on a first plane while the third header tank, the fourth header tank, the second tubes, the second fins, and the vapor-liquid separator of the condenser are located on a second plane, the first plane arranged parallel to the second plane and spaced from the second plane in the first direction.

9. The radiator and condenser assembly of claim 1 , wherein the first header tank, the second header tank, the third header tank, and the fourth header tank extend longitudinally in the third direction, and wherein the first tubes and the second tubes extend longitudinally in the second direction.

10. The radiator and condenser assembly of claim 1 , wherein the lowermost surface of the vapor-liquid separator rests on an uppermost surface of the horizontal part of the fixed bracket to prevent downward movement of the vapor-liquid separator in the third direction.

11. The radiator and condenser assembly of claim 1 , wherein each of the pair of fixed protrusions of the pair of fixed protrusions includes an arcuate surface corresponding in shape to a portion of the outer circumferential surface of the vapor-liquid separator.

12. The radiator and condenser assembly of claim 11 , wherein each of the arcuate surfaces curve around an axis extending in the third direction.

13. The radiator and condenser assembly of claim 2 , wherein the support part includes a base portion and a free end spaced from the base portion.

14. The radiator and condenser assembly of claim 13 , wherein the support part is inclined in the first direction towards the second header tank.

15. The radiator and condenser assembly of claim 13 , wherein the support part is configured to elastically pivot about the base portion, the pivoting of the support part causing the free end to move in the first direction.

16. The radiator and condenser assembly of claim 1 , wherein the upper coupling part includes a U-shaped portion configured to receive the upper bracket.
