The invention discloses a combined type structure of a plate heat pipe and a heat conducting device. The combined type structure comprises a pipe body, a sealed section, a heat insulating section and a heat conducting section. The pipe body comprises a metal shell plate and a containing cavity. The sealed section rolls the metal shell plate so that the two opposite inner walls of the pipe body can be tightly combined, and the containing cavity is divided into a first chamber and a second chamber. The heat insulating section is located on one side of the sealed section and is a hollow chamber comprising the first chamber. The heat conducting section is located on the other side of the sealed section and comprises the second chamber, capillary structures and working fluid. The heat conducting device comprises a heat dissipation shell, a heating assembly and the plate heat pipe. The plate heat pipe is arranged in the heat dissipation shell and connected with the heating assembly in a thermal conductance mode. In this way, heat of the heating assembly is prevented from being accumulated in the heat dissipation shell, and the situation that a user touches the high-temperature shell is avoided.
