DESC:TECHNICAL FIELD
[001] The embodiments herein generally relates to a condenser and more particularly, but not exclusively to a multi row and multi flow condenser with variable fin pitch for automotive vehicle air conditioning.
BACKGROUND
[002] Conventionally in automotive air conditioning system condenser is directly exposed to ambient air through front bumper and grill opening. But in recent automotive production, additional heat exchangers are used in front side of the automotives mainly for auto transmission, hybrid electronics cooling, fuel efficiency and improving emissions. All these extra heat exchangers located in front end of the automotive reduce the air flow to the condenser, which leads to increase in air temperature. Further, the aerodynamic consideration in the modern automotives to improve the fuel economy, drag reductions, stability and safety, narrows the front end and thus leads to reduced front end opening for air to pass to the condenser. Due to the reduced opening, the flow of ambient air to the condenser is reduced. These abovementioned factors affect the overall performance of the condenser.
[003] Therefore, there exists a need for a multi row and multi flow condenser with variable fin pitch for automotive vehicle air conditioning. Further, there exists a need for an optimized multi row and multi flow condenser design for automotive vehicle air conditioning which obviates the aforementioned drawbacks.
OBJECTS
[004] The principal object of the embodiments disclosed herein is to provide a multi row and multi flow condenser having variable fin pitch for automotive vehicle air conditioning.
[005] Another object of an embodiments disclosed herein is to provide an optimized multi row and multi flow condenser design for automotive vehicle air conditioning when additional heat exchangers are positioned in front end of the automotive vehicle.
[006] Yet another object of an embodiments disclosed herein is to provide an optimized multi row and multi flow condenser design for automotive vehicle air conditioning which is easy to assemble when there is a space constraint in the front end of the automotive vehicle.
[007] Still another object of an embodiments disclosed herein is to provide a method of providing a multi row and multi flow condenser having variable fin pitch for automotive vehicle air conditioning.
