The invention relates to the field of machinery, in particular to a plate type heat pipe and a novel pipeline. The plate type heat pipe comprises a body which comprises a bottom wall. The upper side of the bottom wall is provided with one or more heat transfer channels. The inner walls of the heat transfer channels are provided with capillary grooves. Heat transfer media are arranged in the heat transfer channels. The capillary grooves are convex strip-shaped objects. The plate type heat pipe and the novel pipeline have the beneficial effects of being easy to manufacture, beneficial to batch production and extremely high in flexibility. The body is provided with heat conductors, and connectors are arranged between the heat conductors. The connectors are made of aluminum which is a good heat conducting material and has good toughness. In order to meet the requirement that the heat conductors make contact with various heat sources, the heat conductors different in width can be obtained freely in a cutting manner and other manners. The difficulty that as for copper pipes and common flat plate heat pipes, heat dissipation of the outer circles and the inner circles of circular or semicircular heat conductors cannot be achieved is overcome. The plate type heat pipe and the novel pipeline are worthy of being popularized on a large scale.
