双重反转式轴流送风机
摘要：
本发明提供一种双重反转式轴流送风机，其在结合第一及第二分割壳体单元时，能够防止第一及第二分割壳体单元损伤。与第一分割壳体单元(11)的第一凸缘部(19)一体地形成卡合构件(23A～23D)和第一止动部(25A～25D)。第一止动部(25A～25D)与卡合构件(23A～23D)邻接地配置。与第二分割壳体单元(13)的第二凸缘部(37)一体地形成被卡合构件(41A～41D)和第二止动部(43A～43D)。第二止动部(43A～43D)与被卡合构件(41A～41D)邻接地配置，并且具有在卡合构件(23A～23D)与被卡合构件(41A～41D)完全卡合的状态下与第一止动部(25A～25D)的前端部对接的前端部。
摘要（英）：

The invention provides a counter-rotating axial-flow fan which is able to prevent the first and second divided housing units from damaging when coopling with the first and second divided housing units. Engaging members (23A to 23D) and first stopper portions (25A to 25D) are integrally formed with a first flange portion (19) of the first divided housing unit (11). The first stopper portions (25A to 25D) are arranged adjacent to the engaging members (23A to 23D). Engaged members (41A to 41D) and second stopper portions (43A to 43D) are integrally formed with a second flange portion (37) of thesecond divided housing unit (13). The second stopper portions (43A to 43D) are arranged adjacent to the engaged members (41A to 41D). The second stopper portions have leading ends that are abutted onto leading ends of the first stopper portions (25A to 25D) when the engaging members (23A to 23D) are completely engaged with the engaged members (41A to 41D).
