The upper end of the first header tank is located above the lower end of the second header tank. The first header tank has a branching control section promoting a flow of liquid-phase refrigerant from the first header tank into the first heat exchange tubes of the fourth heat exchange path. The branching control section includes a space forming member which forms a closed refrigerant inflow space communicating with the first heat exchange tubes, and a liquid accumulation space. The space forming member has a communication portion for communication between a lower portion of the refrigerant inflow space and the liquid accumulation space.

Abstract: A condenser includes first and second header tanks provided at one end thereof such that the latter is located on the outer side of the former. First heat exchange tubes forming a first heat exchange path provided in a condensation part are connected to the first header tank. Second heat exchange tubes forming a second heat exchange path provided in a super-cooling part are connected to the second header tank. The first header tank has one communication section which communicates with the second header tank through a communication part and to which all the heat exchange tubes forming the first heat exchange path are connected. The communication part is provided at a height below the uppermost heat exchange tube among all the heat exchange tubes connected to the communication section. The upper end of the first header tank is located above the lower end of the second header tank.

Abstract: A condenser has, at one end, a first header tank to which first heat exchange tubes of third and fourth heat exchange paths are connected and a second header tank to which second heat exchange tubes of first and second heat exchange paths are connected. The upper end of the first header tank is located above the lower end of the second header tank. A plate member fixed to the circumferential wall of the first header tank serves as a partition portion for dividing the interior of the first header tank into a first region with which the first heat exchange tubes of the fourth heat exchange path (refrigerant super-cooling path), and a second region located above the first region. An internal volume reduction portion for reducing the internal volume of the first header tank is provided in the first region. The condenser is used for a car air conditioner.

Abstract: A double-wall-tube heat exchanger has an outer tube, and an inner tube disposed concentrically in and spaced apart from the outer tube. A clearance between the outer tube and the inner tube and the interior of the inner tube serve as respective refrigerant flow paths. The inner tube has a plurality of interior fins formed on its inner circumferential surface. The interior fins project radially inward; extend in a longitudinal direction of the inner tube; and are arranged at circumferential intervals. The inner tube has a plurality of elongated projections formed on its outer circumferential surface. The elongated projections project radially outward; extend in the longitudinal direction; and are arranged at circumferential intervals. The interior fins are greater in height than the elongated projections. The double-wall-tube heat exchanger exhibits excellent heat exchange performance.

Abstract: A multi-bored flat tube has outermost unit passages located at both ends of the tube and intermediate unit passages between the outermost unit passages. The outermost unit passage has a circular-based inner surface in cross-section, such as a circumferentially smooth curved shape in cross-section like a perfect circular shape or elliptical shape, or has a circular-based inner surface in cross-section having a plurality of inner fins extending in a longitudinal direction of the tube. The intermediate unit passage has a non-circular based cross-sectional shape, such as rectangular, triangular, trapezoidal, or circular based shape including a plurality of inner fins. The tube is strong against being hit by a stone and has a high heat exchanging performance.
