Non-uniform channel array micro-column flat plate heat pipe

The invention relates to a non-uniform channel array micro-column flat plate heat pipe which comprises a bottom plate and a cover plate, ribs are machined on the bottom plate to form a plurality of parallel axial channels at unequal intervals, and a transverse channel with a certain width is reserved at one end of the bottom plate. The heat pipe is divided into an evaporation section and a condensation section, the evaporation section is an axial channel, and the condensation section is provided with transverse grooves on the basis of ribs to form spaced cube array micro-columns. The cover plate and the bottom plate are welded and sealed to form a closed cavity, and the cavity is filled with a liquid working medium to form the non-uniform channel array micro-column flat plate heat pipe. The non-uniform channels of the flat heat pipe reduce the liquid backflow resistance and improve the backflow efficiency of a working medium, and the condensation section array micro-columns increase the contact heat exchange
