Combined radiator structure

The invention discloses a combined radiator structure which is at least composed of two fins, chamfering areas are arranged on the two sides of each fin, a backflow area is arranged between every two adjacent fins, and the backflow areas and the chamfering areas on the fins on the two sides form a bowl-shaped flow channel. A plurality of hemispherical pits connected with the backflow area are evenly formed in the bottom of the bowl-shaped flow channel, and the opening direction of the hemispherical pits is consistent with that of the bowl-shaped flow channel. According to the combined radiator, the heat dissipation area of the heat dissipation fins can be increased to a large extent under the condition that the number of the heat dissipation fins is limited, meanwhile, flow is guided to the backflow area in the middle of the bowl-shaped flow channel through the chamfering areas on the two sides, vortexes are generated at the hemispherical pits, internal disturbance is intensified, and the heat dissipation eff
