A turbine blade cooling system according to an embodiment includes: a first turn (60, 160) for redirecting a first flow of gas flowing through a first channel (28) of a turbine blade (6) into a central plenum (44) of the turbine blade (6); and a second turn (70, 170) for redirecting a second flow of gas flowing through a second channel (38) of the turbine blade (6) into the central plenum (44); wherein the first turn (60, 160) is offset from the second turn (70, 170) to reduce impingement of the first flow of gas and the second flow of gas in the central plenum (44). 根据实施例的种涡轮叶片冷却系统包括：第转向部(60,160)，其用于将流动穿过涡轮叶片(6)的第通道(28)的第气体流再引导到涡轮叶片(6)的中心仓室(44)中；以及第二转向部(70,170)，其用于将流动穿过涡轮叶片(6)的第二通道(38)的第二气体流再引导到中心仓室(44)中；其中第转向部(60,160)与第二转向部(70,170)偏移，以减少中心仓室(44)中的第气体流和第二气体流的冲击。
