Car Radiator Design: Tips, Challenges & Solutions

Click For Summary
SUMMARY

The discussion focuses on the challenges of designing a car radiator, specifically addressing whether to treat it as a crossflow heat exchanger or utilize a specialized methodology. The user performed calculations assuming internal flow in tubes and external flow over a cylindrical body, resulting in an excessive heat transfer area of 1 sq. m for a 14kW radiator. Participants emphasize the importance of considering the surface area of the heat-conducting components and suggest researching suppliers like Giffin Radiator for further insights.

PREREQUISITES
  • Understanding of heat exchanger types, specifically crossflow heat exchangers.
  • Familiarity with thermal calculations related to fluid dynamics.
  • Knowledge of heat transfer principles, particularly in automotive applications.
  • Experience with radiator design and material selection.
NEXT STEPS
  • Research the design principles of crossflow heat exchangers.
  • Study the thermal performance calculations for automotive radiators.
  • Explore the specifications and offerings of Giffin Radiator and similar suppliers.
  • Learn about optimizing surface area for heat transfer in radiator designs.

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.
