Abstract
The automotive radiators are one of the most important ancillary equipment of the vehicle engines. This appliance cooling the engines with circulation of cooling fluid between the engine block and the radiator. The mass of the ancillary equipment is an important viewpoint, so every saved kilogram means performance growth and can help to achieve a cost-effective operation. Even though under-sizing of this thermal energy system cause life span decreasing.
The objective of the present numerical study is to investigate the thermal characteristics of various plate fins with various fin pitches. Computational fluid dynamics models of fin and tube heat exchanger with different fin patterns are developed to investigate the fin pattern behavior on the heat transfer. To validate these numerical results, measures have been made. To modeling an automotive radiator, a personal computer water cooling kit is used. The temperatures of the cooling fluid and the volume flow of the air and the cooling fluid can be measured. In case of identical values, with the computational fluid dynamics method the effect of the fin patterns can be investigated. This study demonstrates, contextualizes and communicates the advantages of structural and material efficient fin design in conjunction with energy efficiency from large-scale application.
