Refrigerant condenser used for automotive air conditioner

摘要

A tube inside passage height (Tr) is set within a range of 0.35–0.8 mm. Thereby, sum of radiation performance reduction due to pressure loss inside tube and radiation performance reduction due to air flow resistance is reduced, thereby attaining high radiation performance. Especially, when the tube inside passage height (Tr) is set within a range of 0.5–0.7 mm, the radiation performance is further improved.
