Abstract:
1. A refrigerant condenser comprising: a plurality of tubes including refrigerant passages therein, said tubes being laminated; a fin disposed in an air flow passage defined between each of the adjacent tubes; and header tanks disposed at both longitudinal ends of said tubes and communicating with said refrigerant passage, wherein said refrigerant passage defines a height thereof in a tube lamination direction as a tube inside passage height (Tr), and the tube inside passage height (Tr) is set within a range of 0.5-0.7 mm; wherein a dimension between an outer surface of said tube and a top of said refrigerant passage in the tube lamination direction is defined as a tube outer periphery thickness Td, the tube outer periphery thickness Td is set no greater than 0.3 mm, a height of said tubs in the tube lamination direction is defined as tube height Th, an interval between each of the adjacent tubes is defined as tube pitch Tp, a ratio of the tube height Th to the tube pitch Tp (Th/Tp) is defined as air flow opening ratio (Pr), and the air flow opening ratio (Pr) is set in accordance with following formula expression,
