Heat transfer calculation for a 14kW car radiator design

[bilal_gikian]

Dear All,

I am facing a problem in radiator design as I was unable to get a full fledge design procedure about the topic. Do I need to consider it as a crossflow heat exchanger or there is a specialized methodology? I performed some calculations by considering the flow of hot fluid as internal flow in tubes and flow of air as flow over a cylindrical body of length L but my calculations are giving me a heat transfer are of 1 sq. m which is too much for a 14kW radiator.
So my question is that does anyone have the right process details to cope with the challenge?

I will be very thankful if you people come up with useful ideas.
Thanks in advance.

You need to consider the surface area of the heat conducting parts of the radiator!
