    摘要： To form a corrugated fin-type heat exchanger such that the direction in which louvers are cut and raised is inclined in one direction only, and improve the heat transfer performance above that of conventional fins.
    To satisfy the relationship To satisfy the relationship H > Qup / Qup − 1 × ΔH .
    H represents the core height of the heat exchanger,
    Qup represents the ratio of the amount of heat exchanged per mountain between one-directional louver fins and multi-directional louver fins in an airflow part,
    and ΔH represents the amount of increase in a heat transfer reduction region of a heat exchanger core as a result of changing from multi-directional louver fins to one-directional louver fins.

    摘要： Conditions are found for a heat sink having the highest heat exchange performance on the basis of mutual relationship among thickness of each plate, slit pitch, and horizontal rib, in a laminated heat sink core in which numerous parallel slits are punched in a plate, slender vertical ribs are disposed therebetween and the plate is laminated.
    At the laminated heat sink core in which a thickness T of each plate 4 is 0.8 mm to 1.6 mm, each horizontal rib 3 is disposed in a zigzag pattern in a horizontal cross-section orthogonal to the horizontal rib 3, and a refrigerant meanders in an extension direction of the vertical rib 2 in the lamination direction between each of horizontal ribs 3 of the laminated plates 4, the laminated heat sink core is configured so as to satisfy following formulae, where T is the thickness of each plate 4, P is a pitch between horizontal ribs 3 facing a circulation direction of the refrigerant, B is a length in the circulation direction of the horizontal rib 3, and A is a distance in the circulation direction between horizontal ribs 3 adjacent in the zigzag pattern. P/T = 3.0 to 6.0, and A/P = 0.15 to 0.37, where P = 2A + 2B.

    摘要： To provide a stacked plate heat exchanger having a structure that can be temporarily fixed by a simple structure in brazing, without using additional expensive parts. A stacked plate heat exchanger includes a top plate 2, a bottom plate 3 and a plurality of inner plates 4, wherein an upwardly bent tab part 10 is formed on at least one of the plates, a cutout part 11 is formed in plates other than the plate on which the tab part 10 is formed, and each plate is stacked and fixed to one another with the tab part 10 and the cutout part 11 in a fitted state.

    摘要： While a resin tank body 5 and a header plate 1 are positioned, a packing 7 is held between the tank body 5 and the header plate 1 to secure sealing performance. Therewith, the width in a longer axis direction of an opening of a flat tube 3 is set to be wider and the width of the tank body 5 is set to be relatively narrow, to thereby give a compact tank structure. The resin tank body 5 is caused to protrude a number of tooth parts 10 at a constant interval, a tube end release part 11 is formed between the tooth parts 10, and a side edge 3a in a longitudinal axis direction of an opening 3b of the flat tube 3 is positioned therein. Then, among the tooth part 10, a flange part 6, a seal face 1a of the header plate 1 and a peripheral wall 8, a packing accommodation part 12 is formed, and a tip edge 10b of the tooth part 10 is seated on an edge 4a of a convex part 4. Further, the packing 7 is arranged between the packing accommodation part 12 and the seal face 1a.

    摘要： Provided are corrugated fins that have high heat transfer performance and do not cause clogging even in a gaseous environment in which particulate matter such as dust is present. Each wall surface 3 of corrugated fins comprises alternating parallel ridges 4 and furrows 5 with an angle of inclination of 10-60°. Defining Wh as the height of the ridges and furrows, Wp as the pitch of the ridges and furrows, Pf as the pitch of the corrugated fins, and Tf as the thickness of the fins, the following conditions hold. Wh ≦ 0.3674 ⋅ Wp + 1.893 ⋅ Tf − 0.1584 , 0.088 Wh − Tf / Pf 0.342 , and a ⋅ Wp 2 + b ⋅ Wp + c Wh , where a = 0.004 ⋅ Pf 2 − 0.0696 ⋅ Pf + 0.3642 , b = − 0.0036 ⋅ Pf 2 + 0.0625 ⋅ Pf − 0.5752 , and c = 0.0007 ⋅ Pf 2 + 0.1041 ⋅ Pf + 0.2333.
