Abstract and Keywords

Abstract: Wind tunnel test was conducted to study on the air-side heat transfer and flow resistance performance for 22 types of ribbon-tubular radiators with rectangular corrugated fin under different structure parameters. By using multiple linear regression, the mathematical models of air-side heat transfer factor j and friction factor f of the radiator were constructed based on 361 experimental data for predicting the heat transfer and resistance characteristics. The result shows that in the Reynolds number range of 400 to 3 840, the maximum relative errors between the calculated and experimental values of air-side heat dissipation and pressure drop of the radiator are 9.14% and 10.05%, respectively, and the standard errors are 8.62% and 3.75%, respectively. Model predictions are in good agreement with the experimental results.

Keywords: ribbon-tubular radiator; rectangular corrugated fin; heat transfer factor; friction factor; wind tunnel test
