The invention discloses a vertical heat pipe heat exchanging device, which is an A type vertical heat pipe heat exchanging device or a B type vertical heat pipe heat exchanging device. The A type vertical heat pipe heat exchanging device comprises a heat exchange bin, a flow guiding plate, a support and a heat exchange device; the B type vertical heat pipe heat exchanging device comprises a heat exchange bin, a support and a heat exchange device; the heat exchange device comprises heat pipes, heat conducting pipes, heat conducting media and fixing strips; the heat pipes comprise metal pipes, heat conducting working media, fins and M-shaped flow guiding devices; and the M-shaped flow guiding devices comprise V-shaped flow guiding plates and side plates, and fixed to the pipe inner walls ofthe metal pipes. The liquid heat conducting working media of the condensing sections of the heat pipes of the heat exchange device are subjected to multi-stage flow dividing through the V-shaped flowguiding plates of the M-shaped flow guiding devices, thus the conducting heat exchange speed for condensing of heat energy on the metal pipes is increased, the heat exchange efficiency of gas, liquidand particle materials in a drying bin is improved, the heat exchange speed of the heat energy is increased, and thus the heat energy can be conducted and exchanged well; and when one of the heat pipes is damaged and leaks, using of the whole vertical heat pipe heat exchanging device is not influenced.
