  • FIG. 4 is a cross-sectional view corresponding to the BB cross section of FIG. 2 of one piece of the plate fin shown in FIG. 3. It is a relationship graph of the flat part length F of the step direction peak part of the plate fin shown in FIG. 2, and the air side heat transfer coefficient (alpha) ratio.
  • the heat transfer coefficient at the collision surface is high and the heat transfer coefficient at the separation surface is low.
  • the heat transfer coefficient at the separation surface is low.
  • the heat transfer coefficient can be improved as an average value.
  • the heat transfer area can be increased by the mountain portion 5, the heat transfer performance can be improved also by this. If only the heat transfer coefficient improvement on the fin side is considered, all the heights of the ridges 5 in the row direction need only be increased. Since the input to is increased, it is not preferable for energy saving.

Abstract

L'invention concerne un échangeur de chaleur du type à ailettes et tubes ayant un rendement plus élevé réalisé par l'amélioration du coefficient de transmission de chaleur des ailettes sans augmentation de la résistance à l'écoulement de l'air (perte de pression). L'échangeur de chaleur du type à ailettes et tubes (1) a un grand nombre d'ailettes-plaques (2) arrangées de manière parallèle selon un pas prédéterminé et permettant à l'air de s'écouler entre les ailettes-plaques, et a également des tubes de transfert de chaleur (4) insérés en contact étroit dans des trous de tubes (3) mis en œuvre sur les ailettes-plaques (2) selon un pas entre-rangs prédéterminé et selon un pas entre-colonnes prédéterminé et permettant au fluide de s'écouler dans les tubes de transfert de chaleur. Une ailette-plaque (2) a une section conique (6) se trouvant entre les trous de tubes (3) de manière adjacente dans la direction des colonnes et s'étendant dans la direction des colonnes. Sur la partie supérieure de la section conique (6) se trouve une section plate (7).
