In Many Refrigeration Applications, the Evaporator Is a Plain-Fin-And-Tube Heat Exchanger, With A Fin Spacing Of 5-10 Mm. These Heat Exchangers Are Widely Used Because They Are Reliable, Inexpensive, and Relatively Tolerant to Frost Accumulation.Unfortunately, This Heat Exchanger Geometry Does Not Provide a Very High Air-Side Heat Transfer Coefficient. Enhancing the Air-Side Thermal-Hydraulic Performance Of Plain-Fin-And-Tube Heat Exchangers Can Lead to Smaller, Lighter, And More Energy Efficient Refrigeration Systems. In This Research We Examine the Use Of Vortex Generators As an Air-Side Enhancement Technique For Refrigeration Evaporators.
