Title
(EN) TUBE FOR HEAT-EXCHANGER
(JA) 熱交換器用チューブ
Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a tube for a heat-exchanger, capable of exhibiting a desired heat radiating capability while reducing the flow resistance of a circulation medium by optimizing the pitch between adjacent dimple parts in the longitudinal direction of the tube.

SOLUTION: The tube 1 has a plurality of pairs of dimple parts 6 and 7 in the longitudinal direction of the tube 1. The pair of dimple parts 6 and 7 are disposed in such a way that ends 8d on one side are disposed on the line Z1 parallel to the tube 1 in the longitudinal direction, and that the respective center axes 8e are inclined in opposite directions from each other with the line Z1 in-between. When the projected length of the line Z1 in each dimple part 6 or 7 in the tube 1 is L1 and the pitch between the adjacent dimple parts 6 or 7 in the longitudinal direction of the tube 1 is L2, the relation between L2 and L1 is; L2=L13 to 12.

【課題】 チューブの長手方向に隣接するディンプル部同士間のピッチを最適化することにより、流通媒体の通水抵抗を低くしつつ所望の放熱性能を発揮できる熱交換器用チューブの提供。
【解決手段】 それぞれの一方側端部8dをチューブ1の長手方向と平行な線Z1上に配置し、且つ、それぞれの中心軸8eを線Z1を挟んで互いに反対側に傾斜した状態で配置した一対のディンプル部6,7をチューブ1の長手方向に亘って複数形成したチューブ1において、各ディンプル部6,7における線Z1に対する投影長さをL1とし、チューブ1の長手方向に隣接するディンプル部6,7同士間のピッチをL2とした場合、L2=L1×3〜12とした。
