Description

A SEAL FOR A CONDENSER

TECHNICAL FIELD

The present invention relates to a seal for a heat exchanger. In particular, the present invention relates to seal for a condenser for a motor vehicle.

BACKGROUND

Generally, a condenser comprises a plurality of tubes fluidically connected between two manifolds. Further, the condenser comprises an end tube from the plurality of tubes at each end acting as a blind tube. Since the condenser comprises the end tube unlike a radiator comprising a side plate, it is not possible to use a seal configured to connect to the side plate of the radiator for the condenser to block air bypassing the condenser. To overcome this, a foam seal is used for the condenser as the foam seal can be glued to the end tube of the condenser. However, the foam seal connected to the condenser deteriorates over time, leading to air bypassing the condenser. Therefore, it would be desired to provide a seal for the condenser that can be adapted to connect to the end tube of the condenser. Also, it would be desired to provide the seal for the condenser that can be durable and function reliably over time.
