A combination structure of heat dissipation module includes a heat dissipation set and at least one heat pipe, which is extended through the heat dissipation set. The heat dissipation set includes a first, a second, and a third portion, which are located respectively corresponding to a heat-dissipation section, a curved section, and a heat-absorption section of the heat pipe. The second and the third portion of the heat dissipation set are respectively provided with a plurality of second and third slots, which are gradually extended according to a length of the curved section and a horizontal length of the heat-absorption section of the heat pipe, and the third portion internally defines a receiving opening communicable with the third slots, so as to effectively remove heat through using the curved section of the heat pipe.
