The utility model relates to a reinforced uniform-temperature composite heat dissipation device. The heat dissipation device comprises a heat dissipation main body, a heat dissipation liner and a plurality of V-shaped heat pipes, the evaporation sections of the V-shaped heat pipes are distributed in an annular gap between the outer wall of the heat dissipation inner container and the inner wall of the heat transfer cavity of the heat dissipation body, the condensation sections extend outwards in the oblique upward direction, and the included angle alpha between the evaporation sections and the condensation sections ranges from 20 degrees to 70 degrees. The V-shaped heat pipes are adopted, so that heat is subjected to phase change heat transfer on the side face of the heat dissipation inner container and in all directions of the fins, the V-shaped heat pipes are matched with the heat dissipation inner container, the overall performance of the radiator can be improved, the heat conductivity coefficient in all d
