Novel heat pipe heat exchanger

The utility model discloses a novel heat pipe heat exchanger which comprises a frame used for vertically supporting a plurality of heat pipes, a middle partition plate is arranged at the top end of the frame, and an upper collecting box and a lower collecting box are sequentially arranged above the middle partition plate from top to bottom. A plurality of heat pipes sequentially and vertically penetrate through the upper collecting box, the lower collecting box and the middle partition plate from top to bottom to enter the bottom end of the frame, each heat pipe is sleeved with a water sleeve, the two ends of each water sleeve are vertically connected between the upper collecting box and the lower collecting box, and a cooling water flow guide mechanism extending in the axis direction is arranged between the outer portion of each heat pipe and the inner wall of the corresponding water sleeve. The utility model can prevent the air column in the heat pipe from reducing the heat exchange effect, reduce the maint
