Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a heat exchanger capable of improving heat transfer performance.SOLUTION: A heat exchanger has a structure such that intervals of gaps between adjacent tubes 211, 211 are not uniform. A tube 211 has a fin 220 cut and raised from its surface to be formed in one body. The fin 220 has a first fin piece 221 arranged in a gap between adjacent tubes 211, 211 and a second fin piece 222 arranged where the gap between the adjacent tubes 211, 211 is relatively wider than the first fin part 221. A cutting and raising height of the second fin piece 222 is relatively larger than a cutting and raising height of the first fin piece 221.SELECTED DRAWING: Figure 2
【課題】伝熱性能を向上させることのできる熱交換器を提供する。【解決手段】熱交換器は、隣り合うチューブ211,211間の隙間の間隔が不均一な構造を有する。チューブ211には、その表面から切り起こされるようにフィン220が一体的に形成されている。フィン220は、隣り合うチューブ211,211間の隙間に配置される第1フィン片221と、隣り合うチューブ211,211間の隙間が第1フィン部221よりも相対的に広い部分に配置される第2フィン片222とを有する。第2フィン片222の切り起こし高さは、第1フィン片221の切り起こし高さよりも相対的に高い。【選択図】図2 |
