THE “PSEUDO SINGLE ROW” RADIATOR DESIGN

Radiator is a device used to cool internal combustion engine by radiating heat out via a fluid called coolant which is being circulated around the engine. Current generation radiators consist of two header tanks placed on bottom and top interlinked by a passage of tubes, which are flattened in order to maximize the surface area. It is made up of brass or copper soldered to brass headers, but to save money aluminum tubes with plastic headers may also be used. The coolant is circulated by a centrifugal pump, which forces cooled coolant around the engine block where it absorbs the engine heat. This results in the expansion of the fluid causing the pressure to increase in the system. A pressure valve is provided which in case of excess pressure will allow the out flow of some fluid in exchange of some air thus maintaining pressure. The size of radiator is determined by the need of heat dissipation during the peak heat generation periods keeping in account the heat dissipation during idle speed conditions.
