  • In order to gain a deeper understanding of the convective heat transfer capability of spiral curled fin heat exchanger, this paper conducts a study on the convective heat transfer characteristics of spiral curled fin heat exchanger in air from two aspects: heat transfer flow and the compactness of the heat exchanger, using numerical simulation methods. The effects of dimensionless tube spacing (T/D), dimensionless fin height (H/D), and dimensionless fin spacing (S/D) on the heat transfer and flow characteristics of spiral curled fins were studied. The research results indicate that a smaller T/D will increase the flow capacity of the finned tube bundle, thereby increasing convective heat transfer. With the increase of H/D, the heat transfer area of the spiral curled fin tube bundle increases, and the total heat transfer increases. However, the heat dissipation is not sufficient, which affects the efficiency of the spiral curled fins. When the S/D is large, the compactness of the spiral curled fins decreases, the resistance of the tube bundle decreases, and the average volume heat transfer density also decreases. The research results of this article have obtained the influence of different parameters on the heat transfer and flow characteristics of spiral curled fins, which has good guiding significance for the design of spiral curled fins.
