Description
本発明に係る空気調和機の熱交換器は、空気通過方向に空気が通過するように間隔を空けて積層された複数のフィンと、複数のフィンに直交するように挿入され、内部を冷媒が通過し、空気通過方向に対して垂直方向の段方向へ複数段設けられた複数の扁平管とを備えた熱交換部を備え、熱交換部が積層方向に曲げ部を有し、扁平管は、その断面の長軸方向が空気通過方向となるように、フィンの風下側端部に設けられた管挿入部に挿入され、フィンにおいて隣接する扁平管の間の部分である伝熱部は、風上側と風下側とのそれぞれにフィンピッチ調整用の切り起こしを備え、少なくとも風上側の切り起こしは、その切り起こし面が空気通過方向に沿うようにフィンに配置され、フィンは、扁平管の端よりも突出して段方向に連続する排水部を形成し、フィンの排水部の突出長さをX、扁平管の長軸方向の長さをYとしたとき、0.05≦X/Y≦0.4としたものである。 The heat exchanger of the air conditioner according to the present invention includes a plurality of fins stacked at intervals so that air passes in the air passing direction, and is inserted so as to be orthogonal to the plurality of fins, and a refrigerant is contained inside. A heat exchanging section that includes a plurality of flat tubes that pass through and are provided in a plurality of stages in a step direction perpendicular to the air passage direction, the heat exchanging section has a bent portion in the stacking direction, The heat transfer part, which is a part between the flat tubes adjacent to each other in the fin, is inserted into the tube insertion part provided at the leeward side end of the fin so that the major axis direction of the cross section is the air passage direction. comprising a raised each cut for full Inpitchi adjust the windward side and the leeward side, the cut and raised at least windward side, cut-and-raised surface thereof is disposed in the fin along the air passage direction, full fin is flat drainage portion continuous in the column direction to protrude from the end of the tube Formed, when the protruding length of the drainage portion of the full fin X, the longitudinal length of the flat tubes and the Y, is obtained by a 0.05 ≦ X / Y ≦ 0.4.
図11は、角度α=0°とし、風下側の切り起こし27の空気通過方向に対する角度βを変えたときの圧損[Pa]と角度β[゜]との関係を示す図である。この場合も角度β=0°のとき、通風抵抗は最小となり圧損が最小となる。しかし、角度βによる圧損の変化は角度αによる圧損の変化に比べて小さい。これは切り起こし27の風上側にあるリブ25が通風抵抗であるため、リブ25の後流で渦が発生し、切り起こし27に流入するためである。α=0°のとき、リブ25が排水路を流れる凝縮水にとって流路抵抗となる場合は、図3のABを扁平管31の左端よりも右側に配置してもよい。 FIG. 11 is a diagram showing the relationship between the pressure loss [Pa] and the angle β [°] when the angle α = 0 ° and the angle β of the leeward cut and raised 27 with respect to the air passage direction is changed. Also in this case, when the angle β = 0 °, the ventilation resistance is minimized and the pressure loss is minimized. However, the change in pressure loss due to the angle β is smaller than the change in pressure loss due to the angle α. This is because the rib 25 on the windward side of the cut-and-raised 27 has ventilation resistance, so that a vortex is generated behind the rib 25 and flows into the cut-and-raised 27. When α = 0 °, the rib 25 may provide flow path resistance for the condensed water flowing through the drainage channel, and AB in FIG. 3 may be arranged on the right side of the left end of the flat tube 31.
