Abstract

Sealing members for vehicle radiator assemblies and vehicle radiator assemblies comprising sealing members are disclosed. In one embodiment, a sealing member for a radiator assembly includes a central panel, a mounting connector, and a flexible skirt element. The mounting connector may be formed in an upper edge of the central panel and extend across a width of the central panel. The mounting connector and the central panel are formed from a first polymeric material. The flexible skirt element may be formed in a lower edge of the central panel and extend across the width of the central panel. The flexible skirt element may be formed from a second polymeric material that is elastically deformable and recoverable. The first polymeric material may be relatively harder than the second polymeric material. The sealing member may be coupled to a radiator assembly installed in an engine compartment of a vehicle.

Claims

1. A sealing member for a radiator assembly, the sealing member comprising:

a central panel;

a mounting connector formed in an upper edge of the central panel and extending across a width of the central panel, wherein the mounting connector and the central panel are formed from a first polymeric material; and

a flexible skirt element formed in a lower edge of the central panel and extending across the width of the central panel, wherein the flexible skirt element is formed from a second polymeric material that is elastically deformable and recoverable, the first polymeric material being relatively harder than the second polymeric material.

2. The sealing member as claimed in claim 1, wherein the mounting connector comprises a plurality of forward sealing ribs and aft sealing ribs that extend in a direction of the width of the central panel.

3. The sealing member as claimed in claim 2, wherein the forward sealing ribs and the aft sealing ribs are elastically deformable with respect to the mounting connector.

4. The sealing member as claimed in claim 2, wherein at least one of the forward sealing ribs or the aft sealing ribs are formed from the second polymeric material.

5. The sealing member as claimed in claim 1, wherein at least one of the first polymeric material and the second polymeric material comprises ethylene propylene diene monomer.

6. The sealing member as claimed in claim 1, wherein the first polymeric material comprises ethylene propylene diene monomer and the second polymeric material comprises ethylene propylene diene monomer and polypropylene.

7. A radiator assembly comprising:

a radiator;

a lower flange member coupled with the radiator; and

a sealing member comprising a flexible skirt element, the flexible skirt element being deformable and recoverable, wherein;

the sealing member is coupled with the lower flange member; and

the flexible skirt element of the sealing member extends below a bottom of the radiator.

8. The radiator assembly as claimed in claim 7, further comprising a condenser coupled with a front of the radiator and the lower flange member is coupled with a bottom of the condenser.

9. The radiator assembly as claimed in claim 7, wherein the sealing member further comprises a mounting connector and a central panel having a width, an upper edge, and a lower edge, wherein the upper edge of the central panel is coupled with a mounting connector and extends across the width of the central panel and the flexible skirt element is coupled with the lower edge of the central panel and extends across the width of the central panel.

10. The radiator assembly as claimed in claim 9, wherein the sealing member further comprises a plurality of forward sealing ribs and aft sealing ribs formed that extend in a direction of the width of the central panel.

11. The radiator assembly as claimed in claim 9, wherein the mounting connector and the central panel of the sealing member are formed from a first polymeric material and the flexible skirt element of the sealing member is formed from a second polymeric material, the first polymeric material being relatively harder than the second polymeric material.

12. The radiator assembly as claimed in claim 11, wherein at least one of the first polymeric material and the second polymeric material comprises ethylene propylene diene monomer.

13. A vehicle comprising:

a radiator-support member extending across a width of an engine compartment of the vehicle; and

a radiator assembly positioned on the radiator-support member, the radiator assembly comprising;

a radiator;

a lower flange member coupled with the radiator; and

a sealing member coupled with the lower flange member, the sealing member comprising a flexible skirt element, the flexible skirt element being elastically deformable and recoverable, wherein the sealing member extends from the lower flange member and rests on the radiator-support member, the flexible skirt element of the sealing member conforming to a shape of the radiator-support member.

14. The vehicle as claimed in claim 13, wherein the radiator assembly further comprises a condenser coupled with a front of the radiator, wherein the lower flange member is coupled with a bottom of the condenser.

15. The vehicle as claimed in claim 13, wherein the radiator-support member comprises a contoured surface.

16. The vehicle as claimed in claim 13, wherein the sealing member further comprises:

a central panel comprising a width, an upper edge, and a lower edge; and

a mounting connector coupled with the upper edge of the central panel and extending across the width of the central panel, wherein;

the mounting connector and the central panel are formed from a first polymeric material; and

the flexible skirt element is coupled with the lower edge of the central panel and extends across the width of the central panel, the flexible skirt element being formed from a second polymeric material, the first polymeric material being relatively harder than the second polymeric material.

17. The vehicle as claimed in claim 16, wherein the mounting connector further comprises a plurality of forward sealing ribs and aft sealing ribs extending in a direction of the width of the central panel.

18. The vehicle as claimed in claim 17, wherein at least one of the forward sealing ribs and the aft sealing ribs of the sealing member are formed from the second polymeric material.

19. The vehicle as claimed in claim 16, wherein at least one of the first polymeric material or the second polymeric material comprise ethylene propylene diene monomer.

20. The vehicle as claimed in claim 13, further comprising a second sealing member, wherein the second sealing member is coupled with a side of the radiator assembly and the flexible skirt element of the second sealing member conforms to a shape of a wall of the engine compartment.
